keepalived添加服务自启动报错分析

时间：2022-06-02 11:53:56

安装完keepalived后设置为服务自启动

将路径为/usr/local/src/keepalived-1.3.4/keepalived/etc/init.d的文件keepalived拷贝到/etc/init.d下

cp /usr/local/src/keepalived-1.3./keepalived/etc/init.d/keepalived /etc/init.d/

将路径为/usr/local/keepalived-1.3.4/etc/sysconfig/keepalived的文件拷贝到 /etc/sysconfig/keepalived

cp /usr/local/keepavlied-1.3./etc/sysconfig/keepalived  /etc/sysconfig/

添加执行权限

chmod +x /etc/init.d/keepalived

添加keepalived到系统服务

chkconfig --add keepalived

启动

[root@localhost ~]# service keepalived start

Starting keepalived (via systemctl):  Job for keepalived.service failed because the control process exited with error code. See "systemctl status keepalived.service" and "journalctl -xe" for details.

[失败]

报错，启动失败，用status查看具体原因

[root@localhost ~]# systemctl status keepalived

提示：ExecStart=/usr/sbin/keepalived $KEEPALIVED_OPTIONS (code=exited, status=203/EXEC)

查看ll /usr/sbin/keepalived 文件不存在，此时有两种方法解决

1、复制一个keepalived到/usr/sbin/ 下

2、修改 /lib/systemd/system/keepalived.service文件，将 /usr/sbin/路径改成我们存放keepalived文件的路径

[root@localhost ~]# vi /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/local/bin/keepalived $KEEPALIVED_OPTIONS

ExecReload=/bin/kill -HUP $MAINPID

[Install]

3、生效

systemctl daemon-reload

4、再启动

[root@localhost keepalived-1.3.]# systemctl start keepalived

[root@localhost keepalived-1.3.]# systemctl status keepalived
