Question

我对IBM Liberty服务器和Bluemix都相对较新。我现有的Web应用程序在本地WebSphere Liberty服务器（版本8.5.5.7）中部署为战争，运行正常，没有任何问题。

然而，当我将war文件推送到IBM Bluemix Liberty服务器时，真正的问题出现了。我试图推送本地应用程序的方法有两种。

选项1

这里我将我的应用程序作为战争导出为目标运行时作为IBM组下的WebSphere Liberty服务器，然后使用cf push <appname> -p <app.war>

这在上传时不会给我任何错误，但我无法使用给定的上下文根访问该应用程序。

赞http://<appname>.mybluemix.net/<<root>>/login.jsp 其中<<appname>>是应用程序的名称，<<root>>是war文件的名称。

通过这些配置，我可以访问部署在本地Liberty服务器中的应用程序，但不能访问 Bluemix。在这里，Bluemix无法找到Web应用程序的上下文。

选项2

在这里，我按照下面的链接链接，尝试了那里提到的所有步骤：

https://developer.ibm.com/answers/questions/25346/liberty-profile-with-webapp-zip-package-onto-the-bluemix-problem.html

我用war打包整个服务器，并尝试部署整个server.zip

server.bat package defaultServer ––include=usr
cf push icmconsole -p E:\softwares\liberty\wlp-javaee7-8.5.5.7\wlp\usr\servers\defaultServer\defaultServer.zip

上传实例崩溃后，似乎在日志中显示以下错误：

2015-10-15T13:58:29.10+0530 [API/0]      OUT App instance exited with guid 50ff6
9b3-58de-4453-b795-2c58cf1b3fdc payload: {"cc_partition"=>"default",     "droplet"=>

within health check timeout", "crash_timestamp"=>1444897709}

我的server.xml文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<server description="new server">

    <!-- Enable features -->
    <featureManager>
        <feature>javaee-7.0</feature>

    <!-- For the keystore, default keys are generated and stored in a keystore. To provide the keystore password, generate an encoded password using bin/securityUtility encode and add it below in the password attribute of the keyStore element. Then uncomment the keyStore element. -->
    <!-- <keyStore password=""/> -->
    <!--For a user registry configuration, configure your user registry. For example, configure a basic user registry using the basicRegistry element.

    <basicRegistry id="basic" realm="BasicRealm">

你们可以对我的问题嗤之以鼻吗？看起来我缺少一些配置。任何帮助将不胜感激。

Answer 1

选项1

更简单。我相信你应该工作，问题是你可能试图从错误的根上下文启动应用程序。

当您使用选项1时，您的war文件将由Liberty buildpack在内部修改。它将您的war文件重命名为myapp.war并将根上下文放在＆＃34; /＆＃34;。

因此，根据您的情况，您应该可以从以下位置访问您的应用程序：

http://<appname>.mybluemix.net/login.jsp

您不必指定根目录。

选项2

更复杂。我在本地运行一个简单的测试，它工作正常。

这是我做的：

我将我的Java应用程序从Eclipse部署到Liberty服务器的本地实例
我运行以下命令来创建zip文件（需要先停止服务器）：

服务器包defaultServer --include = usr
上面的命令创建了defaultServer.zip并将其复制到我的app目录
我运行以下命令来推送应用程序：

cf push app-name -p defaultServer.zip

一切正常，但这次我可以从原始根目录访问我的应用程序，如下所示：

http://<appname>.mybluemix.net/<root>/login.jsp

我可以从您的帖子中看到的主要区别是我的server.xml包含了战争定义而我没有web.xml个文件。

这是我的server.xml：

<server description="new server">

    <!-- Enable features -->
    <featureManager>
        <feature>javaee-7.0</feature>
        <feature>localConnector-1.0</feature>
    </featureManager>

        <!-- This template enables security. To get the full use of all the capabilities, a keystore and user registry are required. -->

        <!-- For the keystore, default keys are generated and stored in a keystore. To provide the keystore password, generate an 
             encoded password using bin/securityUtility encode and add it below in the password attribute of the keyStore element. 
             Then uncomment the keyStore element. -->
        <!--
        <keyStore password=""/> 
        -->

        <!--For a user registry configuration, configure your user registry. For example, configure a basic user registry using the
            basicRegistry element. Specify your own user name below in the name attribute of the user element. For the password, 
            generate an encoded password using bin/securityUtility encode and add it in the password attribute of the user element. 
            Then uncomment the user element. -->
        <basicRegistry id="basic" realm="BasicRealm"> 
                <!-- <user name="yourUserName" password="" />  --> 
        </basicRegistry>

    <!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
    <httpEndpoint httpPort="9080" httpsPort="9443" id="defaultHttpEndpoint"/>


    <applicationMonitor updateTrigger="mbean"/>

    <webApplication id="HelloJavaWorld" location="HelloJavaWorld.war" name="HelloJavaWorld"/>

    <webApplication id="HelloServlet" location="HelloServlet.war" name="HelloServlet"/>
</server>
