MySQL主从复制--MySQL5.6基于GTID及多线程复制

大纲
一、系统环境
二、MySQL初始化安装过程
三、基于GTID的主从模式配置过程

一、系统环境系统环境CentOS5.8 x86_64master.network.com master 172.16.1.101slave.network.com slave 172.16.1.105软件包mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz(二进制通用安装包)

拓扑图



二、MySQL初始化安装过程1、时间同步

[root@master ~]# ntpdate s2c.time.edu.cn
[root@slave ~]# ntpdate s2c.time.edu.cn

可根据需要在每个节点上定义crontab任务
[root@master ~]# which ntpdate
/sbin/ntpdate
[root@master ~]# echo "*/5 * * * * /sbin/ntpdate s2c.time.edu.cn &> /dev/null" >> /var/spool/cron/root
[root@master ~]# crontab -l
*/5 * * * * /sbin/ntpdate s2c.time.edu.cn &> /dev/null

2、主机名称要与uname -n保持一致，并通过/etc/hosts解析

master
[root@master ~]# hostname master.network.com
[root@master ~]# uname -n
master.network.com
[root@master ~]# sed -i 's@\(HOSTNAME=\).*@\1master.network.com@g'  /etc/sysconfig/network

slave
[root@slave ~]# hostname slave.network.com
[root@slave ~]# uname -n
slave.network.com
[root@slave ~]# sed -i 's@\(HOSTNAME=\).*@\1slave.network.com@g'  /etc/sysconfig/network

master添加hosts解析
[root@master ~]# vim /etc/hosts
[root@master ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1		CentOS5.8 CentOS5 localhost.localdomain localhost
::1		localhost6.localdomain6 localhost6
172.16.1.101	master.network.com 	master
172.16.1.105	slave.network.com 	slave

拷贝此hosts文件至slave
[root@master ~]# scp /etc/hosts slave:/etc/
root@slave's password:
hosts                  100%  233     0.2KB/s   00:00

3、关闭iptables和selinux

master
[root@master ~]# service iptables stop
[root@master ~]# vim /etc/sysconfig/selinux
[root@master ~]# cat /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#	enforcing - SELinux security policy is enforced.
#	permissive - SELinux prints warnings instead of enforcing.
#	disabled - SELinux is fully disabled.
#SELINUX=permissive
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
#	targeted - Only targeted network daemons are protected.
#	strict - Full SELinux protection.
SELINUXTYPE=targeted

slave
[root@slave ~]# service iptables stop
[root@slave ~]# vim /etc/sysconfig/selinux
[root@slave ~]# cat /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#	enforcing - SELinux security policy is enforced.
#	permissive - SELinux prints warnings instead of enforcing.
#	disabled - SELinux is fully disabled.
#SELINUX=permissive
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
#	targeted - Only targeted network daemons are protected.
#	strict - Full SELinux protection.
SELINUXTYPE=targeted

4、Master安装并配置MySQL

数据目录底层最好是个逻辑卷，我这里就不再演示逻辑卷的创建了，我的博文中有，此处没有使用逻辑卷

准备数据目录并添加mysql用户
[root@Master ~]# mkdir -pv /mydata/data
mkdir: created directory `/mydata'
mkdir: created directory `/mydata/data'
[root@Master ~]# groupadd -g 3306 mysql
[root@Master ~]# useradd -u 3306 -g mysql -M -s /sbin/nologin -d /mydata/data/ mysql
[root@Master ~]# chown -R mysql.mysql /mydata/data/

解压并初始化mysql
[root@Master ~]# cd /tmp/
[root@Master tmp]# tar xf mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz -C /usr/local/
[root@Master tmp]# cd /usr/local/
[root@master local]# ln -sv mysql-5.6.26-linux-glibc2.5-x86_64  mysql
create symbolic link `mysql' to `mysql-5.6.26-linux-glibc2.5-x86_64'
[root@Master local]# cd mysql
[root@Master mysql]# chown -R root.mysql ./*
[root@master mysql]# ll

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h master.network.com password 'new-password'

Alternatively you can run:

./bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/

WARNING: Found existing config file ./my.cnf on the system.
Because this file might be in use, it was not replaced,
but was used in bootstrap (unless you used --defaults-file)
and when you later start the server.
The new default config file was created as ./my-new.cnf,
please compare it with your file and take the changes you need.

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

复制服务启动脚本
[root@Master mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
[root@Master mysql]# chkconfig --add mysqld

增加PATH环境变量并使之生效
[root@master mysql]# echo 'export PATH=$PATH:/usr/local/mysql/bin/mysql' > /etc/profile.d/mysql.sh
[root@master mysql]# . /etc/profile.d/mysql.sh

将mysql5.6.26的安装包复制到slave节点上

5、Slave安装并配置MySQL

准备数据目录并添加mysql用户
[root@slave ~]# mkdir -pv /mydata/data
mkdir: created directory `/mydata'
mkdir: created directory `/mydata/data'
[root@slave ~]# groupadd -g 3306 mysql
[root@slave ~]# useradd -u 3306 -g mysql -M -s /sbin/nologin -d /mydata/data/ mysql
[root@slave ~]# chown -R mysql.mysql /mydata/data/

解压并初始化mysql
[root@slave ~]# cd /tmp/
[root@slave tmp]# tar xf mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz -C /usr/local/
[root@slave tmp]# cd /usr/local/
[root@slave local]# ln -sv mysql-5.6.26-linux-glibc2.5-x86_64  mysql
create symbolic link `mysql' to `mysql-5.6.26-linux-glibc2.5-x86_64'

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

./bin/mysqladmin -u root password 'new-password'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/

Support MySQL by buying support/licenses at http://shop.mysql.com 
New default config file was created as ./my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

复制服务启动脚本
[root@slave mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
[root@slave mysql]# chkconfig --add mysqld

三、基于GTID的主从模式配置过程
1、编辑master的配置文件

编辑配置文件，就在当前目录下(/usr/local/mysql)
[root@master mysql]# vim my.cnf
[mysqld]
binlog-format=ROW
log-bin=master-bin
log-slave-updates=true
gtid-mode=on
enforce-gtid-consistency=true
master-info-repository=TABLE
relay-log-info-repository=TABLE
sync-master-info=1
slave-parallel-workers=2
binlog-checksum=CRC32
master-verify-checksum=1
slave-sql-verify-checksum=1
binlog-rows-query-log_events=1
server-id=1
report-port=3306
port=3306
datadir=/mydata/data
innodb_file_per_table = ON
socket=/tmp/mysql.sock
report-host=172.16.1.101

补充
binlog-format：二进制日志的格式，有row、statement和mixed几种类型；
需要注意的是：当设置隔离级别为READ-COMMITED必须设置二进制日志格式为ROW
现在MySQL官方认为STATEMENT这个已经不再适合继续使用；
但mixed类型在默认的事务隔离级别下，可能会导致主从数据不一致；
log-slave-updates、gtid-mode、enforce-gtid-consistency、report-port和report-host：用于启动GTID及满足附属的其它需求；
master-info-repository和relay-log-info-repository：启用此两项，可用于实现在崩溃时保证二进制及从服务器安全的功能；
sync-master-info：启用之可确保无信息丢失；
slave-paralles-workers：设定从服务器的SQL线程数；0表示关闭多线程复制功能；
binlog-checksum、master-verify-checksum和slave-sql-verify-checksum：启用复制有关的所有校验功能；
binlog-rows-query-log-events：启用之可用于在二进制日志记录事件相关的信息，可降低故障排除的复杂度；
log-bin：启用二进制日志，这是保证复制功能的基本前提；
server-id：同一个复制拓扑中的所有服务器的id号必须惟一；

启动服务并查看gtid是否生效
[root@master mysql]# service mysqld start

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)

4、启动从节点的复制线程

mysql> CHANGE MASTER TO MASTER_HOST='master.network.com', MASTER_USER='repuser', MASTER_PASSWORD='reppass', MASTER_AUTO_POSITION=1;
Query OK, 0 rows affected, 2 warnings (0.30 sec)

显示警告信息
mysql> SHOW WARNINGS\G
*************************** 1. row ***************************
Level: Note
Code: 1759
Message: Sending passwords in plain text without SSL/TLS is extremely insecure.
*************************** 2. row ***************************

5、测试复制功能

在master上创建一个测试库
mysql> CREATE DATABASE mydb;
Query OK, 1 row affected (0.08 sec)

mysql> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mydb               |
| mysql              |
| performance_schema |
| test               |
+--------------------+
5 rows in set (0.01 sec)

然后在slave上查看是否有此库
mysql> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mydb               |                 # 可以看到复制功能已然实现
| mysql              |
| performance_schema |
| test               |
+--------------------+
5 rows in set (0.00 sec)

此时master上可以查看到slave的相关信息
mysql> SHOW SLAVE HOSTS;
+-----------+--------------+------+-----------+--------------------------------------+
| Server_id | Host         | Port | Master_id | Slave_UUID                           |
+-----------+--------------+------+-----------+--------------------------------------+
|        11 | 172.16.1.105 | 3306 |         1 | ec8230c2-bc18-11e5-9813-000c296634d1 |
+-----------+--------------+------+-----------+--------------------------------------+
1 row in set (0.03 sec)
