Keepalived + nginx 实现高可用web负载均衡 -- 配置文件

! Configuration File for keepalived
global_defs {
    ## keepalived 自带的邮件提醒需要开启 sendmail 服务。建议用独立的监控或第三方 SMTP
    router_id debiao02  ## 标识本节点的字条串，通常为 hostname
}
## keepalived 会定时执行脚本并对脚本执行的结果进行分析，动态调整 vrrp_instance 的优先级。如果
## 脚本执行结果为 0， 并且 weight 配置的值大于 0， 则优先级相应的增加。 如果脚本执行结果非 0，
## 并且weight配置的值小于 0，则优先级相应的减少。其他情况，维持原本配置的优先级，即配置文件中
## priority对应的值。
vrrp_script chk_nginx {
    script "/etc/keepalived/nginx_check.sh"  ## 检测 nginx 状态的脚本路径
    interval 2  ## 检测时间间隔
    weight -20  ## 如果条件成立，权重-20
}
## 定义虚拟路由，VI_1 为虚拟路由的标示符，自己定义名称
vrrp_instance VI_1 {
    state MASTER  ## 主节点为 MASTER，对应的备份节点为 BACKUP
    interface eth0 ## 绑定虚拟 IP 的网络接口，与本机 IP 地址所在的网络接口相同，我的是 eth1
    virtual_router_id 172  ## 虚拟路由的 ID 号， 两个节点设置必须一样， 可选 IP 最后一段使用, 
    ## 相同的 VRID 为一个组，他将决定多播的 MAC 地址
    mcast_src_ip 192.168.1.172  ## 本机 IP 地址
    priority 100  ## 节点优先级，值范围 0-254，MASTER 要比 BACKUP 高
    nopreempt ## 优先级高的设置 nopreempt 解决异常恢复后再次抢占的问题
    advert_int 1  ## 组播信息发送间隔，两个节点设置必须一样，默认 1s
    ## 设置验证信息，两个节点必须一致
    authentication {
        auth_type PASS
        auth_pass 1111 ## 真实生产，按需求对应该过来
    }
    ## 将 track_script 块加入 instance 配置块
    track_script {
        chk_nginx ## 执行 Nginx 监控的服务
    }
    ## 虚拟 IP 池, 两个节点设置必须一样
    virtual_ipaddress {
        192.168.1.007  ## 虚拟 ip，可以定义多个
    }
