02-keepalived实现对nginx服务的高可用(主备)
实验环境:controller3,controller4为后端web服务器,controller1,controller2为nginx负载均衡服务器,用keepalived实现主备模式的高可用
controller1 IP:9.110.187.120 10.1.1.120
controller2 IP:9.110.187.121 10.1.1.121
controller3 IP:10.1.1.122
controller4 IP:10.1.1.123
1.controller3,controller4安装httpd,提供简单的测试页面
2.controller1,controller2安装nginx,并配置后端服务器组
controller2配置和效果
controller1配置同controller2
3.在controller1上配置keepalived,实现对nginx的高可用
! Configuration File for keepalived global_defs { notification_email { root@localhost #通知邮箱 } notification_email_from keepalived@localhost smtp_server 127.0.0.1 #邮箱服务器 smtp_connect_timeout 30 #邮箱超时时间 router_id controller1 #本机route ID vrrp_mcast_group4 224.0.32.18 #组播地址 } vrrp_instance keepnginx { #自定义虚拟路由实例 state MASTER #本机虚拟路由状态为master interface eno16777736 #心跳传递地址 virtual_router_id 60 #虚拟路由id priority 100 #权重100 advert_int 1 #1秒检测 authentication { #检测方式密码,123456 auth_type PASS auth_pass 123456 } virtual_ipaddress { 9.110.187.60/24 dev eno16777736 label eno16777736:1 #虚拟ip,虚拟ip所在网卡(内网) } } track_interface { #追踪检测网卡 eno16777736 #外网网卡提供访问 eno33554960 #内网网卡访问后端WEB服务器 }
controller2设置为备用
! Configuration File for keepalived global_defs { notification_email { root@localhost } notification_email_from keepalived@localhost smtp_server 127.0.0.1 smtp_connect_timeout 30 router_id controller2 } vrrp_instance keepnginx { state BACKUP interface eno16777736 virtual_router_id 60 priority 99 advert_int 1 authentication { auth_type PASS auth_pass 123456 } virtual_ipaddress { 9.110.187.60/24 dev eno16777736 label eno16777736:1 } } track_interface { eno16777736 eno33554960 }
此时虚拟的Ip 9.110.187.60 因为controller1权重100运行在controller1上,停止controller1的keepalived服务后转移至controller2上,访问9.110.187.60 可轮询方式访问后端vipserver
