问题描述：系统默认每过30s重启一次kylin-kms-activation.service服务，服务无法正常加载就会报错，message日志里面每过30s左右就会刷新一次。

localhost systemd[1]: Stopped run kylin_kms_daemon at boot time.localhost systemd[1]: kylin-kms-activation.service: Start request repeated too quickly.localhost systemd[1]: kylin-kms-activation.service: Failed with result 'exit-code'.

一 系统环境

1.1 服务端/客户端系统版本

[root@localhost ~]# nkvers##############Ky1in Linux Version#################Release:Kylin Linux Advanced Server release V10 (Sword)Kernel:4.19.90-24.4.v2101.ky10.x86_64Build:Kylin Linux Advanced Serverrelease V10(SP2) /(sword)-x86_64-Build09/20210524|#################################################

二 解决方法

2.1 修改kylin-kms-activation.service服务文件

[Unit]字段尾行添加两行参数：
StartLimitInterval=200
StartLimitBurst=1
具体参数解释为：允许最多1次重试，间隔200s

修改完毕之后的配置文件如下[root@localhost ~]# cat  /usr/lib/systemd/system/kylin-kms-activation.service # kylin-activation-check## This unit run kyli_kms_daemon[Unit]Description=run kylin_kms_daemon at boot timeRequires=basic.targetStartLimitIntervalSec=0StartLimitInterval=200StartLimitBurst=1[Service]Type=simpleExecStart=/usr/bin/kylin_kms_daemonRestart=alwaysRestartSec=30[Install]WantedBy=multi-user.target

2.2 重载配置，重启服务

systemctl daemon-reload systemctl restart kylin-kms-activation.service 

2.3 观察日志刷新情况
