Keepalived 解決使用systemctl 無法關閉

修改keepalived.service 檔案

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

修改

KillMode=control-group

• KillMode值釋義：
  • process kill 主程序
  • control-group 殺死程序組，不設定時預設值

指定

PIDFile=keepalived.pid 的生成路徑

，需要注意檔案存放目錄是否有寫入權限

• $MAINPID 為該檔案記錄的值，需要指定pid才可以正确執行reload 和 stop

指定 ExecReload=/bin/kill -HUP $MAINPID

指定 ExecStop=/bin/kill -TERM $MAINPID

完整配置如下

[Unit]
Description=LVS and VRRP High Availability Monitor
After=syslog.target network-online.target

[Service]
Type=forking
PIDFile=/var/run/keepalived.pid
KillMode=control-group
EnvironmentFile=-/etc/sysconfig/keepalived
ExecStart=/usr/sbin/keepalived $KEEPALIVED_OPTIONS
ExecReload=/bin/kill -HUP $MAINPID
ExecStop=/bin/kill -TERM $MAINPID

[Install]
WantedBy=multi-user.target
~
           

之後使用

systemctl stop keepalived

關閉keepalived，

并使用

ps aux | grep keepalived | grep -v grep

檢視程序

[[email protected] keepalived]# systemctl stop keepalived
[[email protected] keepalived]# ps aux | grep keepalived | grep -v grep
           

可以看到 keepalived 程序已關閉

重新啟動後再次檢視

[[email protected] keepalived]# systemctl start keepalived
[[email protected] keepalived]# systemctl status keepalived
