Atlas下载地址: https://github.com/Qihoo360/Atlas/releases
Atlas是出于360的, 比mysql-proxy更稳定, 部署起来更方便。
环境:
proxy:192.168.99.60
master:192.168.99.61
slave:192.168.99.62
1.安装
由于我使用的是rpm包, 直接安装
rpm -ivh Atlas-2.2.el6.x86_64.rpm
就是这么简单, 安装完成。
目录默认在:
/usr/local/mysql-proxy
一览目录结构:
total 16drwxr-xr-x. 2 root root 4096 Dec 12 10:04 bindrwxr-xr-x. 2 root root 4096 Dec 12 11:04 confdrwxr-xr-x. 3 root root 4096 Dec 12 10:04 libdrwxr-xr-x. 2 root root 4096 Dec 12 11:17 log
2.配置文件
cd /usr/local/mysql-proxy/confvim test.cnf
很多中文指示, 完美

3.启动
cd /usr/local/mysql-proxy/bin./mysql-proxyd test start
在这个目录下有mysql-proxy mysql-proxyd, 第一个是mysql团队的, 第二个是属于360团队的, 我们使用的是360的。
端口
netstat -tlnp | grep mysql-proxytcp 0 0 0.0.0.0:1234 0.0.0.0:* LISTEN 7270/mysql-proxy tcp 0 0 0.0.0.0:2345 0.0.0.0:* LISTEN 7270/mysql-proxy
留意您的配置文件: 1234端口是api接口, 提供能外部进行工作连接的, 2345是属于内部管理的, 比如查询负载主机状态等。
