2、proxysql 安装和配置

cat <

3、docker 启动容器

[root@12c proxysql]# docker run -p 3306:3306 --name mysqlmaster -e MYSQL_ROOT_PASSWORD=123456 -d docker.io/centos/mysql-57-centos7
5dd187415052bc46d8daa8b8045f1337c2e1fe4f139d5e6ef6a29be1e408547d
[root@12c proxysql]# docker run -p 3307:3306 --name mysqlslave -e MYSQL_ROOT_PASSWORD=123456 -d docker.io/centos/mysql-57-centos7

4、增加主从必要配置

[root@12c proxysql]# docker exec -it --user root 5 bash

11、配置读写分离组,proxysql会按照规则自动修改server的hostgroup_id

13、配置读写分离路由规则,配置路由前都是用用户的默认规则

[root@12c proxysql]#  mysql -urootuser -p123456 -h292.168.56.11  -P6033 -e "SELECT @@server_id;"
