1. 安装Mysql-proxy关联系统包

    libevent

    libevent-devel

    glib2

    glib2-devel

    lua 5.1.x

    lua-devel-5.1.x

    pkg-config

    mysql-devel

    openssl

    openssl-devel

    gcc*

2安装MySQL-proxy 0.8.5

下载源码包并解压

在源码包路径下安装

./configure –prefix=/u01/mysql-proxy
make
make install

3.配置mysql-proxy.cnf

    内容如下：

[mysql-proxy]
admin-username=root
admin-password=oracle
daemon=true
keepalive= true
proxy-backend-addresses= 10.8.13.207:3307
proxy-read-only-backend-addresses= 10.8.13.178:3306
proxy-lua-script= /u01/mysql-proxy/share/doc/mysql-proxy/rw-splitting.lua
admin-lua-script= /u01/mysql-proxy/share/doc/mysql-proxy/admin.lua
log-file= /var/log/mysql-proxy.log
log-level= debug

4.配置rw-splitting.lua

-- *build a connection pool of min_idle_connections for each backend and maintain
--   its size
-- *
--
--
 
localcommands    =require("proxy.commands")
localtokenizer   =require("proxy.tokenizer")
locallb          =require("proxy.balance")
localauto_config = require("proxy.auto-config")
 
---config
--
--connection pool
if notproxy.global.config.rwsplit then
        proxy.global.config.rwsplit = {
                min_idle_connections = 1,
                max_idle_connections = 2,
 
                is_debug = false
        }
end
 
---
--read/write splitting sends all non-transactional SELECTs to the slaves
--
--is_in_transaction tracks the state of the transactions
localis_in_transaction       = false
 
-- ifthis was a SELECT SQL_CALC_FOUND_ROWS ... stay on the same connections
localis_in_select_calc_found_rows = false
 
---
-- get aconnection to a backend
--
-- as long as we don't have enough connections in the pool,create new connections

视情况配置

5.启动mysql-proxy

/u01/mysql-proxy/bin/mysql-proxy  --defaults-file=/etc/mysql.cnf

6.测试

mysql-proxy 服务器ip为10.8.13.251

 

mysql –utest  -p###### -h10.8.13.251 –P4040

 

在多个mysql客户端连接代理做dml及select操作，可以暂停主从库，看数据查询情况，从而确定mysql-proxy读写分离是否成功。
