基于GTID环境搭建主从复制
1.环境
----------------------------------------------------------|
|mysql版本 | 5.7.14 | 5.7.14 |
|----------|----------------------------------------------|
|ip |192.168.26.233(master) | 192.168.26.75 (slave)|
|port | 3306 | 3306 |
|---------------------------------------------------------|
1. 主库上必须启用两个参数
gtid-mode = on
enforce-gtid-consistency = 1
log-bin = /data/mysql/mysql_3306/logs/mysql-bin
server-id = 3306100
binlog_format = mixed
skip_slave_start=1 数据库起来后不能直接开启复制
2. 查看master库的状态
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000020 | 154 | | | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
Executed_Gtid_Set 是空的
3. insert一条数据
mysql> use zw
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> show tables;
+--------------+
| Tables_in_zw |
+--------------+
| mycode |
| t1 |
+--------------+
2 rows in set (0.00 sec)
mysql> insert into t1 values(2);
Query OK, 1 row affected (0.00 sec)
mysql> show global variables like '%server%';
+---------------------------------+--------------------------------------+
| Variable_name | Value |
+---------------------------------+--------------------------------------+
| character_set_server | utf8 |
| collation_server | utf8_general_ci |
| innodb_ft_server_stopword_table | |
| server_id | 3306100 |
| server_id_bits | 32 |
| server_uuid | 7e354a2c-6f5f-11e6-997d-005056a36f08 |
+---------------------------------+--------------------------------------+
6 rows in set (0.00 sec)
server_uuid : 是 instance的唯一标识
3.创建一个表，插入测试数据
mysql> create table t2 (id int(6));
Query OK, 0 rows affected (0.20 sec)
mysql> insert into t2 values(1);
Query OK, 1 row affected (0.00 sec)
mysql> show master status;
+------------------+----------+--------------+------------------+------------------------------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set
|
+------------------+----------+--------------+------------------+------------------------------------------+
| mysql-bin.000020 | 814 | | | 7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 |
+------------------+----------+--------------+------------------+------------------------------------------+
1 row in set (0.00 sec)
Executed_Gtid_Set 有gtid的信息了
7e354a2c-6f5f-11e6-997d-005056a36f08
7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 后面多了个1-3,1-3就是gtid的事物信息
4.master端备库全库
[root@zw-test-db tmp]# mysqldump -S /tmp/mysql3306.sock -uroot -p --single-transaction --master-data=2 -A >/tmp/full_backup.sql
Enter password:
Warning: A partial dump from a server that has GTIDs will by default include the GTIDs of all transactions, even those that changed
suppressed parts of the database.
If you don't want to restore GTIDs, pass --set-gtid-purged=OFF. To make a complete dump, pass --all-databases --triggers --routines
--events.
会有一个警告: 大概意思是说备份里有GTID的信息，如果不需要GTID的信息，可以加上后面提示的参数过滤掉，这个警告不用管
备份里有gtid的信息
SET @@GLOBAL.GTID_PURGED='7e354a2c-6f5f-11e6-997d-005056a36f08:1-3';
1-3，做同步后，第4个事物会直接传过去
5.将master端的备份到scp到 slave端
[root@zw-test-db tmp]# scp full_backup.sql root@192.168.26.108:/tmp
二 、slave操作：
1.slave端的参数文件
gtid-mode = on
enforce-gtid-consistency = 1
log-bin = /data/mysql/mysql_3306/logs/mysql-bin
relay_log = /usr/local/mysql/log/relay_log
server-id = 3306101
binlog_format =mixed
log-slave-updates = ON
skip_slave_start=1 数据库起来后不能直接开启复制
master_info_repository = table #建议
relay_log_info_repository = table #建议
read_only = on #建议
注意：server-id不能一样
2.重启mysql数据库
[root@llmj-svn-26-81 mysql_3306]# mysqladmin -S /tmp/mysql3306.sock -uroot -p shutdown
Enter password:
[root@llmj-svn-26-81 mysql_3306]# ps -ef|grep mysql
root 9756 9701 0 11:31 pts/2 00:00:00 grep mysq
[root@llmj-svn-26-81 mysql_3306]# mysqld --defaults-file=/data/mysql/mysql_3306/my3306.cnf &
[1] 9762
[root@llmj-svn-26-81 mysql_3306]# mysqld --defaults-file=/data/mysql/mysql_3306/my3306.cnf &
[1] 9762
3.恢复到 slave端
[root@llmj-svn-26-81 tmp]# mysql -S /tmp/mysql3306.sock -uroot -p < /tmp/full_backup.sql
Enter password:
[root@llmj-svn-26-81 tmp]# mysql -S /tmp/mysql3306.sock -uroot -p < /tmp/full_backup.sql
Enter password:
ERROR 1840 (HY000) at line 24: @@GLOBAL.GTID_PURGED can only be set when @@GLOBAL.GTID_EXECUTED is empty.
注意：多次恢复会报错，因为里面已经有gtid的信息了。
如果你还想继续强制恢复，可以在从库上 reset master ;
4.在slave端查看master状态
mysql> show master status;
+------------------+----------+--------------+------------------+------------------------------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+------------------------------------------+
| mysql-bin.000004 | 154 | | | 7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 |
+------------------+----------+--------------+------------------+------------------------------------------+
1 row in set (0.00 sec)
mysql> show global variables like '%gtid%';
+----------------------------------+------------------------------------------+
| Variable_name | Value |
+----------------------------------+------------------------------------------+
| binlog_gtid_simple_recovery | ON |
| enforce_gtid_consistency | ON |
| gtid_executed | 7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 |
| gtid_executed_compression_period | 1000 |
| gtid_mode | ON |
| gtid_owned | |
| gtid_purged | 7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 |
| session_track_gtids | OFF |
+----------------------------------+------------------------------------------+
8 rows in set (0.00 sec)
5.reset master信息
mysql> reset master;
Query OK, 0 rows affected (0.11 sec)
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000001 | 154 | | | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
mysql> show global variables like '%gtid%';
+----------------------------------+-------+
| Variable_name | Value |
+----------------------------------+-------+
| binlog_gtid_simple_recovery | ON |
| enforce_gtid_consistency | ON |
| gtid_executed | |
| gtid_executed_compression_period | 1000 |
| gtid_mode | ON |
| gtid_owned | |
| gtid_purged | |
| session_track_gtids | OFF |
+----------------------------------+-------+
8 rows in set (0.01 sec)
可以看到 gtid_executed 和 gtid_purged 已经没有gtid的信息了
6.然后再重新恢复：
[root@llmj-svn-26-81 tmp]# mysql -S /tmp/mysql3306.sock -uroot -p < /tmp/full_backup.sql
Enter password:
然后就没有报错了，恢复成功！
7.然后 change master to ，这时候跟 binlog+position 有点变化
mysql> change master to master_host='192.168.26.233', master_port=3306, master_user='repl',master_password='repl', master_auto_position=1;
Query OK, 0 rows affected, 2 warnings (0.23 sec)
master_log_file='mysql-bin.000016',master_log_pos=154 这两个参数替换成了 master_auto_position=1
8.启动slave
mysql> start slave;
Query OK, 0 rows affected (0.01 sec)
mysql> show slave status\G;
*************************** 1. row ***************************

三、测试
1. 从库操作：
mysql> show master status;
+------------------+----------+--------------+------------------+------------------------------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+------------------------------------------+
| mysql-bin.000001 | 154 | | | 7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 |
+------------------+----------+--------------+------------------+------------------------------------------+
1 row in set (0.00 sec)
2. 从库上操作，create table ,然后 show master status;
mysql> create table t3(id int(6));
Query OK, 0 rows affected (0.26 sec)
mysql> insert into t3 values (1);
Query OK, 1 row affected (0.00 sec)
mysql> show master status;
+-----------------+--------+-------------+----------------+---------------------------------------------------------------------------------+
| File |Position|Binlog_Do_DB |Binlog_Ignore_DB|Executed_Gtid_Set |
+-----------------+--------+-------------+----------------+---------------------------------------------------------------------------------+
| mysql-bin.000001| 564| | |7e354a2c-6f5f-11e6-997d-005056a36f08:1-3,ba0d5587-74d6-11e6-ab5c-005056a3f46e:1-2|
+-----------------+--------+-------------+----------------+---------------------------------------------------------------------------------+
1 row in set (0.00 sec)
可以看到从库的gtid的信息，也就是说从库的操作可以查出来；1-3是是主库操作的gtid,后面1-2是从库的操作的gtid
四、测试同步情况
1.主库操作：
mysql> use zw;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select * from mycode;
+----+---------+
| id | content |
+----+---------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
| 4 | ddd |
| 5 | eee |
| 7 | ggg |
+----+---------+
6 rows in set (0.00 sec)
2.从库查看mycode表
mysql> select * from mycode;
+----+---------+
| id | content |
+----+---------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
| 4 | ddd |
| 5 | eee |
| 7 | ggg |
+----+---------+
6 rows in set (0.00 sec)
3.主库insert 一条数据
mysql> insert into mycode values(6,'fff');
Query OK, 1 row affected (0.00 sec)
mysql> select * from mycode;
+----+---------+
| id | content |
+----+---------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
| 4 | ddd |
| 5 | eee |
| 6 | fff |
| 7 | ggg |
+----+---------+
7 rows in set (0.00 sec)
4.查看从库
mysql> select * from mycode;
+----+---------+
| id | content |
+----+---------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
| 4 | ddd |
| 5 | eee |
| 6 | fff |
| 7 | ggg |
+----+---------+
7 rows in set (0.00 sec)
从库数据也同步过来啦！
五、MySQL主从同步如何配置数据过滤
主服务器配置：
Binlog-do-db //指定要记录二进制日志的数据库
Binlog-ignore-db //指定要忽略记录二进制日志的数据库
从服务器配置：
Replicate-do-table= //指定要记录二进制日志的表
Replicate-ignore-table= //指定要忽略记录二进制日志的表
Replicate-do-db= //指定要记录二进制日志的数据库
Replicate-ignore-db= //指定要忽略记录二进制日志的数据库
Replicate-wild-do-table= //指定要记录二进制日志的表（支持通配符）
Replicate-wild-ignore-table= //指定要忽略记录二进制日志的表（支持通配符）
1.环境
----------------------------------------------------------|
|mysql版本 | 5.7.14 | 5.7.14 |
|----------|----------------------------------------------|
|ip |192.168.26.233(master) | 192.168.26.75 (slave)|
|port | 3306 | 3306 |
|---------------------------------------------------------|
1. 主库上必须启用两个参数
gtid-mode = on
enforce-gtid-consistency = 1
log-bin = /data/mysql/mysql_3306/logs/mysql-bin
server-id = 3306100
binlog_format = mixed
skip_slave_start=1 数据库起来后不能直接开启复制
2. 查看master库的状态
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000020 | 154 | | | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
Executed_Gtid_Set 是空的
3. insert一条数据
mysql> use zw
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> show tables;
+--------------+
| Tables_in_zw |
+--------------+
| mycode |
| t1 |
+--------------+
2 rows in set (0.00 sec)
mysql> insert into t1 values(2);
Query OK, 1 row affected (0.00 sec)
mysql> show global variables like '%server%';
+---------------------------------+--------------------------------------+
| Variable_name | Value |
+---------------------------------+--------------------------------------+
| character_set_server | utf8 |
| collation_server | utf8_general_ci |
| innodb_ft_server_stopword_table | |
| server_id | 3306100 |
| server_id_bits | 32 |
| server_uuid | 7e354a2c-6f5f-11e6-997d-005056a36f08 |
+---------------------------------+--------------------------------------+
6 rows in set (0.00 sec)
server_uuid : 是 instance的唯一标识
3.创建一个表，插入测试数据
mysql> create table t2 (id int(6));
Query OK, 0 rows affected (0.20 sec)
mysql> insert into t2 values(1);
Query OK, 1 row affected (0.00 sec)
mysql> show master status;
+------------------+----------+--------------+------------------+------------------------------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set
|
+------------------+----------+--------------+------------------+------------------------------------------+
| mysql-bin.000020 | 814 | | | 7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 |
+------------------+----------+--------------+------------------+------------------------------------------+
1 row in set (0.00 sec)
Executed_Gtid_Set 有gtid的信息了
7e354a2c-6f5f-11e6-997d-005056a36f08
7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 后面多了个1-3,1-3就是gtid的事物信息
4.master端备库全库
[root@zw-test-db tmp]# mysqldump -S /tmp/mysql3306.sock -uroot -p --single-transaction --master-data=2 -A >/tmp/full_backup.sql
Enter password:
Warning: A partial dump from a server that has GTIDs will by default include the GTIDs of all transactions, even those that changed
suppressed parts of the database.
If you don't want to restore GTIDs, pass --set-gtid-purged=OFF. To make a complete dump, pass --all-databases --triggers --routines
--events.
会有一个警告: 大概意思是说备份里有GTID的信息，如果不需要GTID的信息，可以加上后面提示的参数过滤掉，这个警告不用管
备份里有gtid的信息
SET @@GLOBAL.GTID_PURGED='7e354a2c-6f5f-11e6-997d-005056a36f08:1-3';
1-3，做同步后，第4个事物会直接传过去
5.将master端的备份到scp到 slave端
[root@zw-test-db tmp]# scp full_backup.sql root@192.168.26.108:/tmp
二 、slave操作：
1.slave端的参数文件
gtid-mode = on
enforce-gtid-consistency = 1
log-bin = /data/mysql/mysql_3306/logs/mysql-bin
relay_log = /usr/local/mysql/log/relay_log
server-id = 3306101
binlog_format =mixed
log-slave-updates = ON
skip_slave_start=1 数据库起来后不能直接开启复制
master_info_repository = table #建议
relay_log_info_repository = table #建议
read_only = on #建议
注意：server-id不能一样
2.重启mysql数据库
[root@llmj-svn-26-81 mysql_3306]# mysqladmin -S /tmp/mysql3306.sock -uroot -p shutdown
Enter password:
[root@llmj-svn-26-81 mysql_3306]# ps -ef|grep mysql
root 9756 9701 0 11:31 pts/2 00:00:00 grep mysq
[root@llmj-svn-26-81 mysql_3306]# mysqld --defaults-file=/data/mysql/mysql_3306/my3306.cnf &
[1] 9762
[root@llmj-svn-26-81 mysql_3306]# mysqld --defaults-file=/data/mysql/mysql_3306/my3306.cnf &
[1] 9762
3.恢复到 slave端
[root@llmj-svn-26-81 tmp]# mysql -S /tmp/mysql3306.sock -uroot -p < /tmp/full_backup.sql
Enter password:
[root@llmj-svn-26-81 tmp]# mysql -S /tmp/mysql3306.sock -uroot -p < /tmp/full_backup.sql
Enter password:
ERROR 1840 (HY000) at line 24: @@GLOBAL.GTID_PURGED can only be set when @@GLOBAL.GTID_EXECUTED is empty.
注意：多次恢复会报错，因为里面已经有gtid的信息了。
如果你还想继续强制恢复，可以在从库上 reset master ;
4.在slave端查看master状态
mysql> show master status;
+------------------+----------+--------------+------------------+------------------------------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+------------------------------------------+
| mysql-bin.000004 | 154 | | | 7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 |
+------------------+----------+--------------+------------------+------------------------------------------+
1 row in set (0.00 sec)
mysql> show global variables like '%gtid%';
+----------------------------------+------------------------------------------+
| Variable_name | Value |
+----------------------------------+------------------------------------------+
| binlog_gtid_simple_recovery | ON |
| enforce_gtid_consistency | ON |
| gtid_executed | 7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 |
| gtid_executed_compression_period | 1000 |
| gtid_mode | ON |
| gtid_owned | |
| gtid_purged | 7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 |
| session_track_gtids | OFF |
+----------------------------------+------------------------------------------+
8 rows in set (0.00 sec)
5.reset master信息
mysql> reset master;
Query OK, 0 rows affected (0.11 sec)
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000001 | 154 | | | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
mysql> show global variables like '%gtid%';
+----------------------------------+-------+
| Variable_name | Value |
+----------------------------------+-------+
| binlog_gtid_simple_recovery | ON |
| enforce_gtid_consistency | ON |
| gtid_executed | |
| gtid_executed_compression_period | 1000 |
| gtid_mode | ON |
| gtid_owned | |
| gtid_purged | |
| session_track_gtids | OFF |
+----------------------------------+-------+
8 rows in set (0.01 sec)
可以看到 gtid_executed 和 gtid_purged 已经没有gtid的信息了
6.然后再重新恢复：
[root@llmj-svn-26-81 tmp]# mysql -S /tmp/mysql3306.sock -uroot -p < /tmp/full_backup.sql
Enter password:
然后就没有报错了，恢复成功！
7.然后 change master to ，这时候跟 binlog+position 有点变化
mysql> change master to master_host='192.168.26.233', master_port=3306, master_user='repl',master_password='repl', master_auto_position=1;
Query OK, 0 rows affected, 2 warnings (0.23 sec)
master_log_file='mysql-bin.000016',master_log_pos=154 这两个参数替换成了 master_auto_position=1
8.启动slave
mysql> start slave;
Query OK, 0 rows affected (0.01 sec)
mysql> show slave status\G;

状态正常！
三、测试
1. 从库操作：
mysql> show master status;
+------------------+----------+--------------+------------------+------------------------------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+------------------------------------------+
| mysql-bin.000001 | 154 | | | 7e354a2c-6f5f-11e6-997d-005056a36f08:1-3 |
+------------------+----------+--------------+------------------+------------------------------------------+
1 row in set (0.00 sec)
2. 从库上操作，create table ,然后 show master status;
mysql> create table t3(id int(6));
Query OK, 0 rows affected (0.26 sec)
mysql> insert into t3 values (1);
Query OK, 1 row affected (0.00 sec)
mysql> show master status;
+-----------------+--------+-------------+----------------+---------------------------------------------------------------------------------+
| File |Position|Binlog_Do_DB |Binlog_Ignore_DB|Executed_Gtid_Set |
+-----------------+--------+-------------+----------------+---------------------------------------------------------------------------------+
| mysql-bin.000001| 564| | |7e354a2c-6f5f-11e6-997d-005056a36f08:1-3,ba0d5587-74d6-11e6-ab5c-005056a3f46e:1-2|
+-----------------+--------+-------------+----------------+---------------------------------------------------------------------------------+
1 row in set (0.00 sec)
可以看到从库的gtid的信息，也就是说从库的操作可以查出来；1-3是是主库操作的gtid,后面1-2是从库的操作的gtid
四、测试同步情况
1.主库操作：
mysql> use zw;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select * from mycode;
+----+---------+
| id | content |
+----+---------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
| 4 | ddd |
| 5 | eee |
| 7 | ggg |
+----+---------+
6 rows in set (0.00 sec)
2.从库查看mycode表
mysql> select * from mycode;
+----+---------+
| id | content |
+----+---------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
| 4 | ddd |
| 5 | eee |
| 7 | ggg |
+----+---------+
6 rows in set (0.00 sec)
3.主库insert 一条数据
mysql> insert into mycode values(6,'fff');
Query OK, 1 row affected (0.00 sec)
mysql> select * from mycode;
+----+---------+
| id | content |
+----+---------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
| 4 | ddd |
| 5 | eee |
| 6 | fff |
| 7 | ggg |
+----+---------+
7 rows in set (0.00 sec)
4.查看从库
mysql> select * from mycode;
+----+---------+
| id | content |
+----+---------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
| 4 | ddd |
| 5 | eee |
| 6 | fff |
| 7 | ggg |
+----+---------+
7 rows in set (0.00 sec)
从库数据也同步过来啦！
五、MySQL主从同步如何配置数据过滤
主服务器配置：
Binlog-do-db //指定要记录二进制日志的数据库
Binlog-ignore-db //指定要忽略记录二进制日志的数据库
从服务器配置：
Replicate-do-table= //指定要记录二进制日志的表
Replicate-ignore-table= //指定要忽略记录二进制日志的表
Replicate-do-db= //指定要记录二进制日志的数据库
Replicate-ignore-db= //指定要忽略记录二进制日志的数据库
Replicate-wild-do-table= //指定要记录二进制日志的表（支持通配符）
Replicate-wild-ignore-table= //指定要忽略记录二进制日志的表（支持通配符）
