CentOS 6.8搭建mysql-proxy实现读写分离：

下载网址： http://ftp.ntu.edu.tw/MySQL/Downloads/MySQL-Proxy

注： 1、10.0.1.2为mysql-proxy服务器ip 2、效果是1个写，2个读

tar zxfv mysql-proxy-0.8.5-linux-el6-x86-64bit.tar.gz -C /space

mv /space/mysql-proxy-0.8.5-linux-el6-x86-64bit /space/mysql-proxy

mkdir /space/mysql-proxy/logs

cp -rv /space/mysql-proxy/share/doc/mysql-proxy/rw-splitting.lua /space/mysql-proxy/

vi /space/mysql-proxy/rw-splitting.lua

if not proxy.global.config.rwsplit then proxy.global.config.rwsplit = { min_idle_connections = 1, （默认为4，即超过4个才会进行读写分离） max_idle_connections = 1, （默认为8）

            is_debug = false
    }

end

：wq

vi /space/mysql-proxy/mysql-proxy.cnf

[mysql-proxy]

proxy-address=10.0.1.2:4040 proxy-backend-addresses=10.0.1.3 proxy-read-only-backend-addresses=10.0.1.4 proxy-read-only-backend-addresses=10.0.1.5 proxy-lua-script=/space/mysql-proxy/rw-splitting.lua log-file=/space/mysql-proxy/logs/mysql-proxy.log log-level=info daemon=true

:wq

chmod 0660 /space/mysql-proxy/mysql-proxy.cnf

/space/mysql-proxy/bin/mysql-proxy --defaults-file=/space/mysql-proxy/mysql-proxy.cnf

ps -ef | grep mysql-proxy

netstat -nplt | grep 4040

关服务可通过kill -9 进程号

客户端访问：

mysql -h 10.0.1.2 -P 4040 -u aa -p'xxxx'
