启动请求重复太快

Question

我正在写一个bash脚本，但我经常遇到这个问题。当我尝试start或stop一个服务时，我经常会得到：

start request repeated too quickly 

我该如何解决这个问题？例如，当我尝试重新启动docker或openshift-origin master时就会出现这种情况。

sudo service origin-master restart

● origin-master.service - Origin Master Service
   Loaded: loaded (/usr/lib/systemd/system/origin-master.service; enabled; vendor preset: disabled)

我的脚本只是在做：

if [ $1 = "-u" ]
then
 sudo service origin-master restart
fi

在我执行脚本之前，手动重启是可能的。但在此之后，它仍然会给出错误

Answer 1

这是systemctl的一个“特性”。文件中有一个参数限制重新启动频率(以秒为单位)。在测试时降低这个值。

编辑文件/etc/systemd/system/multi-user.target.wants/<your service here>

我的例子：

Restart=on-failure
StartLimitBurst=2
# Restart, but not more than once every 10 minutes
#StartLimitInterval=600
# Restart, but not more than once every 30s (for testing purposes)
StartLimitInterval=30

我建议您熟悉一下systemd。这就是您在运行service时在幕后使用的内容。正如@chepner所说，服务正在失败(从日志的第二行可以看到)，并且它被重新启动得太快，从而触发了错误。

尝试运行journalctl -u origin-master.service找出错误发生的原因。

此外，systemd cat origin-master.service将向您显示描述您的服务的服务单元文件-可能存在错误。

我在Ubuntu20.4上遇到了这个问题。通过向ExecStart文件添加execute权限，解决了该问题。

sudo chmod +x /path/to/execfile
