OneProxy读写分离配置操作手册

1.确保已配置好主备集群

　　A）配置

　　　　可参考MySQL官方文档（https://dev.mysql.com/doc/refman/5.6/en/replication-howto.html）

　　　　或者我的博客（http://www.cnblogs.com/youge-OneSQL/p/4579833.html ）

　　B）创建用户

　　　　在主备集群上的MySQL分别执行如下命令：

　　　 mysql -e "grant all privileges on *.* to test@'%' identified by 'test' "

2.下载最新版本OneProxy

　　http://www.onexsoft.cn/software/oneproxy-rhel6-linux64-v5.7-ga.tar.gz

3.解压到指定目录

　　mv oneproxy-rhel6-linux64* /usr/local/

　　tar zxvf oneproxy-rhel6-linux64*

4）更改启动文件

　　cd oneproxy

　　cat demo.sh

#!/bin/bash export ONEPROXY_HOME=/data/oneproxy if [ -f ${ONEPROXY_HOME}/oneproxy.pid ]; then kill -9 `cat ${ONEPROXY_HOME}/oneproxy.pid` fi sleep 2 # valgrind --leak-check=full --show-reachable=yes \ ${ONEPROXY_HOME}/oneproxy --proxy-address=:3307 --proxy-extra-address=:3308 \ --proxy-master-addresses=192.168.1.119:3306@default \ --proxy-user-list=test/1378F6CC3A8E8A43CA388193FBED5405982FBBD3@test \ --proxy-part-tables=${ONEPROXY_HOME}/part.txt \ --proxy-charset=gbk_chinese_ci --proxy-found-rows \ --proxy-group-policy=default:master-only \ --event-threads=6 --proxy-group-security=default:0 \ --log-file=${ONEPROXY_HOME}/oneproxy.log \ --pid-file=${ONEPROXY_HOME}/oneproxy.pid

更改后

#/bin/bash # export ONEPROXY_HOME=/usr/local/oneproxy if [ -f ${ONEPROXY_HOME}/oneproxy.pid ]; then kill -9 `cat ${ONEPROXY_HOME}/oneproxy.pid` fi sleep 2 # valgrind --leak-check=full --show-reachable=yes \ ${ONEPROXY_HOME}/oneproxy --proxy-address=:3307 --proxy-extra-address=:3308 \ --proxy-master-addresses=<IP1>:3306@data1 \ --proxy-slave-addresses=<IP2>:3306@data1 \ --proxy-user-list=test/1378F6CC3A8E8A43CA388193FBED5405982FBBD3@test \ --proxy-part-tables=${ONEPROXY_HOME}/part.txt \ --proxy-charset=utf8_bin --proxy-found-rows \ --proxy-group-policy=data1:read-balance \ --event-threads=6 \ --keepalive \ --log-file=${ONEPROXY_HOME}/oneproxy.log \ --pid-file=${ONEPROXY_HOME}/oneproxy.pid

注释：

A) --proxy-user-list=test/1378F6CC3A8E8A43CA388193FBED5405982FBBD3@test 其中第一个test为连接proxy的用户名，该用户名也是用来连接后端数据库的用户名；1378F6CC3A8E8A43CA388193FBED5405982FBBD3为test用户的加密口令；最后一个test为各个数据库节点中的test数据库。

B) 口令加密。

　　此时可以启动oneproxy

　　cd /usr/local/oneproxy

sh ./demo.sh

进入管理端口,然后键入passwd <string>。

mysql -uadmin -pOneProxy -P4041 --protocol=TCP passwd test

输出为：

1378F6CC3A8E8A43CA388193FBED5405982FBBD3

5) 配置完毕

通过3307端口，即可实现读写分离

mysql -utest -ptest -P3307 -h<IP>

6）重启oneProxy

A) 关闭

　　ps aux | grep oneproxy | awk '{print $2}' | xargs kill -9

注：该方法会关闭在该主机上运行的所有OneProxy实例

B) 启动

cd /usr/local/oneproxy

sh ./demo.sh
