Mysql中如何搭建oneproxy

小编给大家分享一下Mysql中如何搭建oneproxy，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

1 下载
官网：http://www.onexsoft.cn/software/step_into_oneproxy.pdf

2 安装
机器有限，oneproxy就安装在192.168.1.6上
192.168.1.6–主—oneproxy
192.168.1.56—从

3 简单读写分离

1. 插入数据：[chenliang@hostnfsd oneproxy]$ mysql -utestuser -ptestuser -h292.168.1.6 –port=3308 -e "insert into  test2(id) values(4)" testbak; 
   Warning: Using a password on the command line interface can be insecure.
   [chenliang@hostnfsd oneproxy]$ mysql -utestuser -ptestuser -h292.168.1.6 –port=3308 -e "select * from test2" testbak;             
   Warning: Using a password on the command line interface can be insecure.
   +——+——+
   | id   | name |
   +——+——+
   |    1 | NULL |
   |    2 | NULL |
   |    3 | 4    |
   +——+——+

2. 成功插入主库

读负载均衡测试：

1. [chenliang@hostnfsd oneproxy]$ mysql -utestuser -ptestuser -h292.168.1.6 –port=3308 -e "select * from test2" group1;
   Warning: Using a password on the command line interface can be insecure.
   +——+——+
   | id   | name |
   +——+——+
   |    1 | NULL |
   |    2 | NULL |
   |    3 | 4    |
   +——+——+
   [chenliang@hostnfsd oneproxy]$ mysql -utestuser -ptestuser -h292.168.1.6 –port=3308 -e "select * from test2" group1;
   Warning: Using a password on the command line interface can be insecure.
   +——+
   | id   |
   +——+
   |    1 |
   |    2 |
   +——+
   [chenliang@hostnfsd oneproxy]$ mysql -utestuser -ptestuser -h292.168.1.6 –port=3308 -e "select * from test2" group1;
   Warning: Using a password on the command line interface can be insecure.
   +——+——+
   | id   | name |
   +——+——+
   |    1 | NULL |
   |    2 | NULL |
   |    3 | 4    |
   +——+——+
   [chenliang@hostnfsd oneproxy]$ mysql -utestuser -ptestuser -h292.168.1.6 –port=3308 -e "select * from test2" group1;
   Warning: Using a password on the command line interface can be insecure.
   +——+
   | id   |
   +——+
   |    1 |
   |    2 |
   +——+

3. 读负载均衡，均衡分发至每个库

多用户：

1. [root@hostnfsd :/usr/local/oneproxy]$ vi demo.sh 
   #/bin/bash
   #
   export ONEPROXY_HOME=/usr/local/oneproxy

   # valgrind –leak-check=full /

   ${ONEPROXY_HOME}/bin/oneproxy –keepalive /
   –proxy-address=192.168.1.6:3308 /
   –admin-address=192.168.1.6:4041  /
   –proxy-master-addresses=192.168.1.6:3307@group1 /
   –proxy-slave-addresses=192.168.1.56:3307@group1  /
   –proxy-user-list=testuser/950434F7872CB57A600E1B2B7237766FA7E95460@testbak /
   –proxy-user-list=jonn/950434F7872CB57A600E1B2B7237766FA7E95460@testbak2 /   —就这不同，用户指定默认数据库不一样罢了
   –proxy-group-policy=group1:Read-balance /
   –proxy-charset=utf8_chinese_ci /
   –log-file=${ONEPROXY_HOME}/oneproxy.log /
   –pid-file=${ONEPROXY_HOME}/oneproxy.pid

测试：
[root@hostnfsd :/root]$ mysql -ujonn -ptestuser -h292.168.1.6 –port=3308 -e "select * from test2" group1                         —读写分离
