mysql基于GTID的复制方式
Mysql的复制方法一共有四种：基于sql语句、基于行、混合部署、基于GTIDS
GTIDS的使用环境一般在一主多从下使用
GTIDS的环境：
|
角色 |
IP |
|
Master |
192.168.200.101 |
|
Slave |
192.168.200.102 |
实验步骤：
如果不是新安装的mysql，那么我们需要将主节点上的数据导入从节点，达到数据同步。
- 修改MySQL的配置文件
[root@master ~]# vim /etc/my.cnf
[mysqld]
gtid_mode=on
enforce_gtid_consistency=on
server_id=1
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
#binlog
log-bin=mysql-binlog
log-slave-updates=1
binlog_format=row
#relay log
skip_slave_start=1
- 登录mysql进行配置
[root@master ~]# mysql -u root -p
mysql> grant replication slave on *.* to ‘myslave’@’192.168.200.%’ identified by ‘123123’;
Query OK, 0 rows affected, 1 warning (0.01 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
3． 修改从节点mysql配置文件
[root@slave ~]# vim /etc/my.cnf
[mysqld]
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
server-id = 2
log_bin=on
gtid-mode=on
enforce-gtid-consistency=on
read_only=on
#保证从节点的安全性
master_info_repository=TABLE
relay_log_info_repository=TABLE
登录从节点mysql进行配置
[root@slave ~]# mysql -uroot -p
mysql> stop slave;
Query OK, 0 rows affected (0.01 sec)
mysql> change master to master_host=’192.168.200.101′,
-> master_user=’myslave’,
-> master_password=’123123′,
-> master_auto_position=1;
Query OK, 0 rows affected, 2 warnings (0.04 sec)
mysql> start slave;
Query OK, 0 rows affected (0.01 sec)
mysql>show slave status\G’;

- 测试
在主节点上创建数据
mysql> create database test;
Query OK, 1 row affected (0.01 sec)
然后在从节点上查看
mysql> show databases;
