Preface

金沙棋牌app手机下载, 

    I've implemented ProxySQL on PXC yesterday but got some errors when configured query rules.I'm gonna do it again in my master-slave environment again.Let's see the procedure.

 

Procedure

 

Start ProxySQL.

1 [root@zlm1 17:22:46 /var/lib]
2 #service proxysql start
3 Starting ProxySQL: ProxySQL is already running.
4 
5 [root@zlm1 17:23:16 /var/lib]
6 #ps aux|grep proxysql
7 root       666  0.0  0.5  58180  5180 ?        S    15:06   0:00 proxysql -c /etc/proxysql.cnf -D /var/lib/proxysql
8 root       667  0.0  2.0 104152 21068 ?        Sl   15:06   0:02 proxysql -c /etc/proxysql.cnf -D /var/lib/proxysql
9 root      5523  0.0  0.0 112640   960 pts/1    R+   15:55   0:00 grep --color=auto proxysql

 

Login ProxySQL configure the hostgroups.
