我在本机装了3个虚拟机,
3个虚拟机都部署了相同的项目
地址分别为
192.168.20.133:8080
192.168.20.135:8080
192.168.20.136:8080
ngxin安装在133上, 重点配置如下:
因为我135 136 的权重为2, 133的权重为1 ,
我开着3个日志, 每次访问到哪个机器,日志会有滚动来确定访问到哪台虚拟机了
一般顺序为 135 136 135 136 133 135 136 135 136 133 135 136 135 136 133 但也不绝对
我把136的tomcat停止之后, 133 和135能够继续提供服务,保证一台服务器挂掉之后其他服务器继续工作。
所有配置:
