修改keepalived.service 文件

    1. vim /usr/lib/systemd/system/keepalived.service

    修改KillMode=control-group

    • KillMode值释义：
      • process kill 主进程
      • control-group 杀死进程组，不设置时默认值

    指定PIDFile=keepalived.pid 的生成路径，需要注意文件存放目录是否有写入权限

    • $MAINPID 为该文件记录的值，需要指定pid才可以正确执行reload 和 stop

    指定 ExecReload=/bin/kill -HUP $MAINPID
    指定 ExecStop=/bin/kill -TERM $MAINPID

    完整配置如下

    1. [Unit]
    2. Description=LVS and VRRP High Availability Monitor
    3. After=syslog.target network-online.target
    5. [Service]
    6. Type=forking
    7. PIDFile=/var/run/keepalived.pid
    8. KillMode=control-group
    9. EnvironmentFile=-/etc/sysconfig/keepalived
    10. ExecStart=/usr/sbin/keepalived $KEEPALIVED_OPTIONS
    11. ExecReload=/bin/kill -HUP $MAINPID
    12. ExecStop=/bin/kill -TERM $MAINPID
    14. [Install]
    15. WantedBy=multi-user.target
    16. ~

    之后使用 systemctl stop keepalived 关闭keepalived，
    并使用 ps aux | grep keepalived | grep -v grep 查看进程

    1. [root@localhost keepalived]# systemctl stop keepalived
    2. [root@localhost keepalived]# ps aux | grep keepalived | grep -v grep

    可以看到 keepalived 进程已关闭
    重新启动后再次查看

    1. [root@localhost keepalived]# systemctl start keepalived
    2. [root@localhost keepalived]# systemctl status keepalived
