1、启动ipvsadm 服务报错如下：
Job for ipvsadm.service failed because the control process exited with error code. See "systemctl status ipvsadm.service" and "journalctl -xe" for details.
2、通过状态查询，发现缺少 /etc/sysconfig/ipvsadm
systemctl status ipvsadm ● ipvsadm.service - Initialise the Linux Virtual Server Loaded: loaded (/usr/lib/systemd/system/ipvsadm.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since Mon 2021-05-17 04:26:17 EDT; 10s ago Process: 1806 ExecStart=/bin/bash -c exec /sbin/ipvsadm-restore < /etc/sysconfig/ipvsadm (code=exited, status=1/F> Main PID: 1806 (code=exited, status=1/FAILURE) May 17 04:26:17 localhost.localdomain systemd[1]: Starting Initialise the Linux Virtual Server...

3、执行以下命令
ipvsadm --save > /etc/sysconfig/ipvsadm
4、重启服务即可
systemctl restart ipvsadm.service
