安装需要的基础组件,基本系统都可以满足lua的组件版本要求 安装lua(确定是否需要安装) yum -y install gcc* gcc-c++* autoconf* automake* zlib* libxml* ncurses-devel* libmc rypt* libtool* flex* pkgconfig glib* readline-devel libevent-devel

vim /etc/profile LUA_PATH="/usr/local/mysql-proxy/share/doc/mysql-proxy/?.lua" export LUA_PATH export PATH=$PATH:/usr/local/mysql-proxy/bin 保存并退出后执行下面命令 source /etc/profile // 使变量立即生效
修改mysql proxy的读写分离脚本的配置 vim /usr/local/mysql-proxy/share/doc/mysql-proxy/rw-splitting.lua 默认最小4个(最大8个)以上的客户端连接才会实现读写分离, 现改为最小1个最大2个,便于读写分离的测试 -- connection pool if not proxy.global.config.rwsplit then proxy.global.config.rwsplit = { min_idle_connections = 1, // 改为1 max_idle_connections = 2, // 改为2 is_debug = false } end 这是因为mysql-proxy会检测客户端连接, 当连接没有超过min_idle_connections预设值时, 不会进行读写分离, 即查询操作会发生到Master上.

--daemon 采用daemon方式启动 --admin-address=:4401 指定mysql proxy的管理端口,不加参数,默认4041 --proxy-address=:3307 指定mysql proxy的监听端口,不加默认4040 也可以用 127.0.0.1:3307 表示 --proxy-backend-addresses=192.168.1.3:3306 指定master 写的mysql主机的端口 --proxy-read-only-backend-addresses=192.168.1.1:3306 指定只读的mysql主机端口 --proxy-read-only-backend-addresses=192.168.1.2:3306 指定另一个只读的mysql主机端口 --proxy-lua-script=/usr/local/share/mysql-proxy/rw-splitting.lua 指定lua脚本,在这里,使用的是rw-splitting脚本,用于读写分离 --keepalive :在mysql-proxy崩溃时尝试重启之; --plugins=plugin:在mysql-proxy启动时加载的插件; --user=user_name :运行mysql-proxy进程的用户; --defaults-file=/path/to/conf_file_name : 默认使用的配置文件路径;其配置段使用[mysql-proxy]标识; --proxy-skip-profiling : 禁用profile; --pid-file=/path/to/pid_file_name :进程文件名; --plugins=proxy -b 192.168.1.219:3306 -r 192.168.1.177:3306
