Question

在更新插件角色策略插件后，Jenkins无法工作。

我正在使用 jenkins 2.138.1 版本。我已经在“管理插件”部分更新了基于角色的策略插件，并尝试使用jenkinsurl/restart重新启动实例。现在出现以下错误，没有登录界面可见：

今天我遇到了这个错误，我的情况是依赖关系的问题。基于角色的授权策略已经更新到 v3.0 版本，我使用Ansible jenkins_job模块更新插件后重新启动Jenkins失败。浏览器中的错误与服务器返回的错误类似：

如您所见，有一个待处理的插件，似乎Ansible可以根据需要从依赖项更新插件，但无法安装更新的依赖项。

设置类似的解决方案后，备份config.xml，删除安全性，安装依赖项Extended Read Permission，然后恢复配置，我成功地恢复了服务。

我在我的Windows本地机器上运行Jenkins时遇到了相同的错误(rolestrategy.RoleBasedAuthorizationStrategy)。我在这里遇到了相同的错误

进入安装Jenkins的C驱动器上的Jenkins文件夹。
尝试在本地机器中查找config.xml文件。
它可能位于以下位置之一 "C:\Programfiles\Jenkins\.jenkins\config.xml" 或者 "C:\ProgramData\Jenkins\.jenkins\config.xml"
请记住，.jenkins文件夹在Windows机器上默认为隐藏状态，因此首先取消隐藏所有文件夹，然后进入 "C:\Programfiles\Jenkins\" 或 "C:\ProgramData\Jenkins\"
我相信您能够在上述路径中找到config.xml文件，或者直接在Windows上搜索config.xml文件。
找到config.xml后，
首先尝试备份config.xml文件，并将其粘贴到某个地方并妥善保管。
关闭浏览器上的所有Jenkins URL (Localhost:8080)
现在转到Windows > 在Windows上搜索"Services" > 请检查此图像
搜索Jenkins，然后右键单击jenkins并单击STOP 请在此处检查图像
现在转到config.xml，使用记事本打开，并注释/删除所有<authorizationStrategy>块并将<useSecurity>true</useSecurity>更改为<useSecurity>false</useSecurity>。
保存config.xml文件
再次转到Services搜索Jenkins并启动服务
转到浏览器并再次运行localhost:8080，它可以正常工作了。
启动Jenkins（它会正常启动但没有身份验证）。

将config.xml更改回之前的原始版本（包括以前运行的所有安全设置），并使用原始角色策略配置正常工作。

终于解决了 !!!!!!!!

如果在 LINUX 机器上出现此错误，请查看以下 Youtube 链接以获取解决方案。https://www.youtube.com/watch?v=Kn4VwdVB0fs&ab_channel=AmanShukla

检查 /var/lib/jenkins 的所有权。

确保所有者为 jenkins。

chown -R jenkins:jenkins /var/lib/jenkins

这解决了我的问题。

我曾经遇到同样的问题，通过以下方法解决：

关闭Jenkins的URL，这样可以使用它，但每个人都成为管理员。

备份config.xml文件，以便在更改时能恢复之前的内容。

在$JENKINS_HOME/config.xml中注释或删除所有authorizationStrategy块，并将<useSecurity>true</useSecurity>更改为false。

启动Jenkins（它将正常启动，但没有身份验证）。

将config.xml更改回之前的原始版本（包括先前运行的所有安全性），并按照原来的角色策略配置正常工作。
