mysql gitd主从同步配置
GTID原理
配置环境
- 已关闭防火墙、selinux；
- MySQL安装步骤请参照MySQL二进制包安装；
- 所用IP地址如下：
| IP地址 | 角色 | 安装项目 |
|---|---|---|
| 192.168.91.133 | master | MySQL |
| 192.168.91.134 | slave | MySQL |
配置步骤
- 编辑主（master）/etc/my.cnf配置文件
[root@localhost ~]# vim /etc/my.cnf
......
##bin log
server-id=1
log-bin=master-bin
binlog-format=row
log-slave-updates=1
##gtid
gtid-mode=on
enforce-gtid-consistency=on
##relay log
skip-slave-start=1

- 编辑从（salve）/etc/my.cnf配置文件
[root@localhost ~]# vim /etc/my.cnf
......
## bin log
server-id=2
log-bin=slave-bin
binlog-format=row
log-slave-updates=1
##gtid
gtid-mode=on
enforce-gtid-consistency=on
##relay log

- 登录主（master）和从（slave）服务器，创建同步用户并授权
mysql> grant replication slave on *.* to 'repl'@'192.168.91.%' identified by '123456';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

- 重新启动主服务器，并查看主的master状态
[root@localhost ~]# mysql -e "show master status"
+-------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
