yum list installed | grep maxscale 查看是否安装过maxscale yum remove -y maxscale.x86_64 卸载之前的版本 yum install -y maxscale-2.1.3-1.centos.7.x86_64.rpm 安装rpm包

3，mysql增加用户
添加maxscale监控以及获取user表信息的用户
create user 'maxscale'@'%' identified by 'maxscale';
grant select on mysql.user to 'maxscale'@'%';
grant select on mysql.db to 'maxscale'@'%';
grant select on mysql.tables_priv to 'maxscale'@'%';
grant show databases on . to 'maxscale'@'%';
grant replication client on . to 'maxscale'@'%';
(重点)添加连接maxscale代理的客户端用户。(机器多个ip，都要进行添加， 包括内网ip)
client用户，并增加代理访问db的权限。
grant all privileges on . to 'scaleclient'@'192.168.0.62' identified by 'scaleclient';
grant all privileges on . to 'scaleclient'@'192.168.0.63' identified by 'scaleclient';
登录代理若连不上代理，查看log或者是mysql用户权限配置不正确
