查看keepalived.service

# vi /lib/systemd/system/keepalived.service

内容如下

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

[Service]
Type=forking
PIDFile=/usr/local/program/keepalived/var/run/keepalived.pid      ##发现这个目录不存在，无法写入keepalived.pid
KillMode=process
EnvironmentFile=-/usr/local/program/keepalived/etc/sysconfig/keepalived
ExecStart=/usr/local/program/keepalived/sbin/keepalived $KEEPALIVED_OPTIONS
ExecReload=/bin/kill -HUP $MAINPID

[Install]
WantedBy=multi-user.target

问题见

PIDFile=/usr/local/program/keepalived/var/run/keepalived.pid      ##发现这个目录不存在，无法写入keepalived.pid

修改成

PIDFile=/var/run/keepalived.pid  

运行命令

# systemctl daemon-reload    #重新载入 systemd，扫描新的或有变动的单元

在运行就Ok了

service keepalived start
