- 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。
