编辑$JENKINS_HOME/config.xml文件，修改去安全配置如下:

<authorizationStrategy class="hudson.security.AuthorizationStrategy$Unsecured"/>

之后詹金斯重启。

我发现有问题的文件位于/var/lib/jenkins中，名为config.xml，修改后解决了这个问题。

对于使用macOS的用户来说，新版本只能通过自制软件安装。所以为了休息，这个命令行必须使用:

brew services restart jenkins-lts

将< usesecsecurity >true</ usesecsecurity >更改为< usesecsecurity >false</ usesecsecurity >是不够的，你应该删除<authorizationStrategy>和<securityRealm>元素，并通过执行sudo service jenkins restart重启jenkins服务器。

请记住，仅将< usesecsecurity >设置为false可能会给您带来问题，因为这些说明在这里的官方文档中提到了。

关于修改的答案是正确的。然而，我认为应该提到的是，如果你激活了“基于项目的矩阵授权策略”，/var/lib/jenkins/config.xml看起来就像这样。删除/var/lib/jenkins/config.xml并重新启动jenkins也可以做到这一点。我还删除了/var/lib/jenkins/users中的用户，从头开始。

<authorizationStrategy class="hudson.security.ProjectMatrixAuthorizationStrategy">
    <permission>hudson.model.Computer.Configure:jenkins-admin</permission>
    <permission>hudson.model.Computer.Connect:jenkins-admin</permission>
    <permission>hudson.model.Computer.Create:jenkins-admin</permission>
    <permission>hudson.model.Computer.Delete:jenkins-admin</permission>
    <permission>hudson.model.Computer.Disconnect:jenkins-admin</permission>
    <!-- if this is missing for your user and it is the only one, bad luck -->
    <permission>hudson.model.Hudson.Administer:jenkins-admin</permission>
    <permission>hudson.model.Hudson.Read:jenkins-admin</permission>
    <permission>hudson.model.Hudson.RunScripts:jenkins-admin</permission>
    <permission>hudson.model.Item.Build:jenkins-admin</permission>
    <permission>hudson.model.Item.Cancel:jenkins-admin</permission>
    <permission>hudson.model.Item.Configure:jenkins-admin</permission>
    <permission>hudson.model.Item.Create:jenkins-admin</permission>
    <permission>hudson.model.Item.Delete:jenkins-admin</permission>
    <permission>hudson.model.Item.Discover:jenkins-admin</permission>
    <permission>hudson.model.Item.Read:jenkins-admin</permission>
    <permission>hudson.model.Item.Workspace:jenkins-admin</permission>
    <permission>hudson.model.View.Configure:jenkins-admin</permission>
    <permission>hudson.model.View.Create:jenkins-admin</permission>
    <permission>hudson.model.View.Delete:jenkins-admin</permission>
    <permission>hudson.model.View.Read:jenkins-admin</permission>
  </authorizationStrategy>

我也遇到了类似的问题，在收到ArtB的回复后，

我发现我的用户没有正确的配置。所以我做的是:

注意:手动修改此类XML文件存在风险。做这件事的风险自负。既然我已经被锁在门外了，我也没什么可失去的了。最坏的情况下，我会删除~/.jenkins/config.xml文件，就像前面的帖子提到的那样。

* * > 1。SSH到Jenkins机器

cd ~ /。jenkins(我猜有些安装把它放在/var/lib/jenkins/config.xml下，但在我的情况下没有) vi config.xml，在authorizationStrategy xml标签下，添加以下部分(只是使用我的用户名而不是“put your-username”) 重启詹金斯。在我的情况下，根服务tomcat7停止;； 服务tomcat7启动 请重新登录。(为我工作)**

下

add:

<permission>hudson.model.Computer.Build:put-your-username</permission>
<permission>hudson.model.Computer.Configure:put-your-username</permission>
<permission>hudson.model.Computer.Connect:put-your-username</permission>
<permission>hudson.model.Computer.Create:put-your-username</permission>
<permission>hudson.model.Computer.Delete:put-your-username</permission>
<permission>hudson.model.Computer.Disconnect:put-your-username</permission>
<permission>hudson.model.Hudson.Administer:put-your-username</permission>
<permission>hudson.model.Hudson.ConfigureUpdateCenter:put-your-username</permission>
<permission>hudson.model.Hudson.Read:put-your-username</permission>
<permission>hudson.model.Hudson.RunScripts:put-your-username</permission>

<permission>hudson.model.Item.Build:put-your-username</permission>

<permission>hudson.model.View.Read:put-your-username</permission>
<permission>hudson.scm.SCM.Tag:put-your-username</permission>

现在，你可以去不同的方向。例如，我有github oauth集成，所以我可以尝试替换授权策略如下:

注意:，它在我的情况下工作，因为我有一个特定的github oauth插件，已经配置。所以它比之前的解决方案风险更大。

  <authorizationStrategy class="org.jenkinsci.plugins.GithubAuthorizationStrategy" plugin="github-oauth@0.14">
    <rootACL>
      <organizationNameList class="linked-list">
        <string></string>
      </organizationNameList>
      <adminUserNameList class="linked-list">
        <string>put-your-username</string>
        <string>username2</string>
        <string>username3</string>
        <string>username_4_etc_put_username_that_will_become_administrator</string>
      </adminUserNameList>
      <authenticatedUserReadPermission>true</authenticatedUserReadPermission>
      <allowGithubWebHookPermission>false</allowGithubWebHookPermission>
      <allowCcTrayPermission>false</allowCcTrayPermission>
      <allowAnonymousReadPermission>false</allowAnonymousReadPermission>
    </rootACL>
  </authorizationStrategy>
