1.环境说明
| ip | 主机 | 服务 |
|---|---|---|
| 192.168.69.134 | 读写分离解析主机 | proxysql |
| 192.168.69.130 | mysql-master | mysql |
| 192.168.69.132 | mysql-master2 | mysql |
| 192.168.69.5 | mysql-slave | mysql |
| 192.168.69.6 | mysql-slave2 | mysql |
把所有主机关闭防火墙和setLinux
[root@proxysql ~]# setenforce 0
[root@proxysql ~]# systemctl stop firewalld
2.安装proxysql和安装mysql和配置主从

2.2.1配置mysql-master和mysql-master2
[root@mysql-master ~]# mysql

2.2.2登录proxysql管理端
[root@proxysql ~]# export MYSQL_PS1="(\u@\h:\p) [\d]> "
[root@proxysql ~]# mysql -uadmin -padmin -h127.0.0.1 -P6032

Query OK, 97 rows affected (0.01 sec)
添加读写分离的路由规则
需求：
将 select 查询语句全部路由至 hostgroup_id=2 的组(也就是读组)
但是 select * from tb for update 这样的语句是会修改数据的，所以需要单独定义，将它路由至 hostgroup_id=1 的组(也就是写组)
其他没有被规则匹配到的组将会被路由至用户默认的组(mysql_users 表中的 default_hostgroup)
(admin@127.0.0.1:6032) [(none)]> insert into mysql_query_rules(rule_id,active,match_digest,destination_hostgroup,apply)values(1,1,'^SELECT.*FOR UPDATE$',1,1);
Query OK, 1 row affected (0.00 sec)(admin@127.0.0.1:6032) [(none)]> insert into mysql_query_rules(rule_id,active,match_digest,destination_hostgroup,apply)values(2,1,'^SELECT',2,1);

3.验证读写分离
