HTTP 错误：503 ... 访问 /jenkins。原因：服务不可用

Question

我正在尝试在 Jetty 的 /webapps 中部署 Jenkins。我已经把jenkins.war复制到这个目录下，重启了Jetty，但是当我指向http://localhost:8080/jenkins时，系统警告：

HTTP 错误：503 访问 /jenkins 时出现问题。原因：服务不可用

这是我的控制台日志

我该如何解决这个问题？

提前致谢。

Answer 1

尝试在新的 (8.1.X) Jetty 实例中安装 Jenkins 时遇到了同样的错误。似乎有 bug fix 可能引入了这种行为，并且在安装 Jenkins/Hudson 时出现。现在需要明确给出安全领域/登录服务。

在没有严格 Jetty 安全要求的环境中，即：只想让 Jenkins 启动并运行的非 Jetty 爱好者。创建一个包含安全处理程序的上下文文件$JETTY_HOME\contexts\jenkins.xml。

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

  <Set name="contextPath">/jenkins</Set>
  <Set name="war"><SystemProperty name="jetty.home" default="."/>/webapps/jenkins.war</Set>

  <Get name="securityHandler">
    <Set name="loginService">
      <New class="org.eclipse.jetty.security.HashLoginService">
            <Set name="name">Jenkins Realm</Set>
            <Set name="config"><SystemProperty name="jetty.home" default="."/>/etc/realm.properties</Set>
      </New>
    </Set>
  </Get>

</Configure>

希望这会有所帮助！

Answer 2

要使用 Jetty 附带的示例测试 JAAS 模块：

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath">/jenkins</Set>
  <Set name="war"><SystemProperty name="jetty.home" default="."/>/webapps/jenkins.war</Set>
  <Set name="securityHandler">
    <New class="org.eclipse.jetty.security.ConstraintSecurityHandler">
     <Set name="loginService">
       <New class="org.eclipse.jetty.plus.jaas.JAASLoginService">
         <Set name="name">Test JAAS Realm</Set>
         <Set name="loginModuleName">xyz</Set>
       </New>
     </Set>
    </New>
  </Set>
</Configure>

然后分别指向etc/login.conf 和etc/login.properties 中的领域和定义。

按照这个示例，设置您自己的 JAAS 模块应该相对容易。

Answer 3

好吧，我也遇到了同样的问题。以前使用 jenkins repo 安装的

移除 Jenkins

• yum remove jenkins && yum clean all

获得了最新的 rpm

• wget https://pkg.jenkins.io/redhat-stable/jenkins-2.7.4-1.1.noarch.rpm
• rpm -ivh jenkins-2.7.4-1.1.noarch.rpm
• 服务 jenkins 启动

一切都开始得很完美。

Answer 4

Jetty 配置为使用 Java 身份验证和授权服务 (JAAS)。安全性在领域（用户名 + 角色）中定义。

基本上，您所要做的就是告诉 Jetty 为已部署的 jenkins.war 文件使用定义安全性。最简单的方法是创建一个jenkins.xml 文件并将其放在与jenkins.war 文件相同的文件夹中。

文件的内容是（对于 Jetty 9）：

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">
<Configure id='wac' class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath">/jenkins</Set>
  <Set name="war"><Property name="jetty.webapps" default="."/>/jenkins.war</Set>
  <Set name="extractWAR">true</Set>
  <Set name="securityHandler">
    <New class="org.eclipse.jetty.security.ConstraintSecurityHandler">
     <Set name="loginService">
       <New class="org.eclipse.jetty.jaas.JAASLoginService">
         <Set name="name">Test JAAS Realm</Set>
         <Set name="loginModuleName">xyz</Set>
       </New>
     </Set>
    </New>
  </Set>
</Configure>

Answer 5

就我而言，问题是我已切换到 openjdk-1.7，但没有安装“开发”包。切换到 IBM 解决了它。

Answer 6

请注意，如果您最近开始收到此错误，并且认为您可能使用了 AJP 反向代理，那么您可能已经悄悄更新到 Jenkins 2.x，这会破坏这一点。

幸运的是，如果您现在使用 Apache 2.4，这很容易解决 - 您可以使用 HTTP 反向代理，而不是 described here。

我在this post 中写了更多关于此的背景信息。
