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.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>

要在Linux中简单地禁用Jenkins安全性，运行以下命令:

sudo ex +g/useSecurity/d +g/authorizationStrategy/d -scwq /var/lib/jenkins/config.xml
sudo /etc/init.d/jenkins restart

它将从config.xml根配置文件中删除usesecsecurity和authorizationStrategy行，并重新启动Jenkins。

请参见:禁用Jenkins网站的安全性

在获得Jenkins的访问权限后，您可以在配置全局安全性页面中通过选择访问控制/安全领域重新启用安全性。之后不要忘记创建admin用户。

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。

1首先检查位置，如果你安装战争或Linux或windows基于它

例如，如果战争在Linux和admin用户

/ home / User_NAME”。詹金斯/ \用户/行政/ xml配置。

转到#jbcrypt后面的标签:

<passwordHash>#jbcrypt:$2a$10$3DzCGLQr2oYXtcot4o0rB.wYi5kth6e45tcPpRFsuYqzLZfn1pcWK</passwordHash>

使用使用任何网站的bcrypt哈希生成器更改此密码

确保以$2a开头，因为这是jenkens用的

在El-Capitan中，config.xml不能在

/var/lib/jenkins/

它可在

~ / .jenkins

然后，如前所述，打开config.xml文件并进行以下更改

将< usesecsecurity >true</ usesecsecurity >替换为< usesecsecurity >false</ usesecsecurity > 删除<authorizationStrategy>和<securityRealm> 保存它并重新启动jenkins(sudo service jenkins restart)
