詹金斯正在运行，但服务部门表示失败了。
提问于 2021-12-16 06:23:21
由于我已经通过在CentOS7上安装了jenkins 2.319.1，所以我有一个问题，就是我可以通过systemctl启动jenkins作为服务启动jenkins。然后詹金斯将启动一个I可以通过浏览器访问它。但是，如果我试图通过systemctl状态jenkins获得服务的状态。
我首先得到的是：

我刚刚发现相同的jenkins版本运行在不同的CentOS7服务器上，并且服务状态是活动的。
到目前为止，我看到的唯一不同之处是，工作版本没有使用runuser作为第一个命令。

我也遇到了同样的问题并解决了它。这个问题来自于你的/etc/init.d/jenkins。您可能会修改它，并且更新过程(rhel7上的yum)无法替换它。这个“旧文件”与jenkins的新版本不兼容。这就是systemctl命令不能正常工作的原因。

问题是，yum想要安装/etc/init.d/jenkins的新版本。不过，既然我以前编辑过它。新文件已经安装在/etc/init.d/jenkins.rpmnew中，而systemd仍然使用旧的文件。我所做的就是接管我从旧的/etc/init.d/jenkins到新文件的更改。然后删除旧的/etc/init.d/jenkins，将/etc/init.d/jenkins.rpmnew重命名为/etc/init.d/jenkins，并重新启动服务。
