nginx四层负载均衡配置代理Mysql集群
环境如下：
- ip 192.168.6.203 Nginx
- ip 192.168.6.*(多台) Mysql
步骤一
查看Nginx是否安装stream模块
没安装则进行安装 操作步骤如下
pkill nginx
至此 已成功添加stream模块
步骤二
配置 mysql负载均衡案例
修改Nginx配置文件nginx.conf 内容如下图
测试步骤如下
- 后端Mysql需做好读写分离
- 创建好相应权限的用户
- 到客户端连接Nginx创建wuguiyunwei库进行测试
在客户端连接 创建测试库
连接3307读库查看 成功如下
当然为了高可用以下才是我们想要的效果
以上配置只是为了让大家了解stream模块。当然也可以用于生产环境，但还需完善工作如节点down剔除,完善的一些监控工作。。。
以下是实验环境的nginx主配文件
