Mysql主从复制
主库:192.168.114.11
备库:192.168.114.12
(1)首先确保主从服务器上的Mysql版本相同
(2)在主服务器上,设置一个从数据库的账户,使用REPLICATIONSLAVE赋予权限
1.主从安装mysql
安装
启动
删除匿名用户
2.master节点设置
修改my.cnf
说明:
server-id=11中的11可以任定义,但要唯一。
建立帐户并授权salve
说明: IP192.168.114.12为从节点IP。
锁定数据库以防止写入数据
mysql>flush tables with read lock;
导出数据库并传送到备库
重启服务
查看binlog
解锁数据表:
mysql>unlock tables;
QueryOK, 0 rows affected (0.00 sec)
3.slaver节点设置
导入主库数据
[root@rhel65-mysql02~]# mysql -u root -ptan < /tmp/all.sql
配置my.cnf
重启mysql服务
[root@rhel65-mysql02 ~]# /etc/init.d/mysqldrestart
配置从服务
说明:
master_host是主从服务器IP
master_log_file和master_log_pos是前面master用show master status查出来的。
启动slave进程
mysql>start slave;
查看复制状态
注意:
Read_Master_Log_Pos: 384
Slave_IO_Running:Yes
Slave_SQL_Running:Yes
查看日志:
[root@rhel65-mysql02~]# more /var/log/mysqld.log
4.简单测试
主库操作:
备库查看:

1.主从安装mysql
安装
[root@rhel65-mysql01 ~]# yum install mysqlmysql-server
启动
[root@rhel65-mysql01 ~]# /etc/init.d/mysqldstart [root@rhel65-mysql01 ~]# mysql mysql>select version(); +-----------+ |version() | +-----------+ |5.1.71 | +-----------+ 1row in set (0.00 sec) mysql>show databases; +--------------------+ |Database | +--------------------+ |information_schema | |mysql | |test | +--------------------+ 3rows in set (0.00 sec)
删除匿名用户
mysql>use mysql Databasechanged mysql>delete from user where user=''; QueryOK, 2 rows affected (0.00 sec)
2.master节点设置
修改my.cnf
[root@rhel65-mysql01~]# vi /etc/my.cnf [mysqld] log-bin=mysql-bin server-id=11 binlog_ignore_db=mysql
说明:
server-id=11中的11可以任定义,但要唯一。
建立帐户并授权salve
[root@rhel65-mysql01~]# mysql -u root -ptan mysql>create user 'standby'@'192.168.114.12' identified by '123456'; mysql>grant replication salve on *.* to 'standby'@'192.168.114.12' identified by'123456';
说明: IP192.168.114.12为从节点IP。
锁定数据库以防止写入数据
mysql>flush tables with read lock;
导出数据库并传送到备库
[root@rhel65-mysql01~]# mysqldump -u root -ptan --all-database --lock-tables=false -->/tmp/all.sql [root@rhel65-mysql01~]# scp /tmp/all.sql root@192.168.114.12:/tmp
重启服务
[root@rhel65-mysql01~]# /etc/init.d/mysqld restart
查看binlog
mysql>show master status; +------------------+----------+--------------+------------------+ |File | Position |Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ |mysql-bin.000002 | 384 | | mysql | +------------------+----------+--------------+------------------+ 1row in set (0.00 sec)

[root@rhel65-mysql02~]# mysql -u root -ptan < /tmp/all.sql
配置my.cnf
[root@rhel65-mysql02~]# vi /etc/my.cnf [mysqld] log-bin=mysql-bin server-id=12
重启mysql服务
[root@rhel65-mysql02 ~]# /etc/init.d/mysqldrestart
配置从服务
mysql>change master to master_host='192.168.114.11',master_user='standby', master_password='123456',master_port=3306, master_log_file='mysql-bin.000002',master_log_pos=384, master_connect_retry=10;
说明:
master_host是主从服务器IP
master_log_file和master_log_pos是前面master用show master status查出来的。
启动slave进程
mysql>start slave;
查看复制状态
