keepalived停掉后，发现状态依然是running

定位

查看keepalived的启动service文件

systemctl cat keepalived

内容如下：

# /usr/lib/systemd/system/keepalived.service
[Unit]
Description=LVS and VRRP High Availability Monitor
After=syslog.target network-online.target

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

[Install]
WantedBy=multi-user.target

把这一行（KillMode=process）注释掉即可，这行目前只会停止主进程而不会关闭子进程，所以才会出现这个情况
