java - IBM bluemix 迁移war 文件

Question

我对 IBM Liberty 服务器和 Bluemix 都比较陌生。我现有的 Web 应用程序作为 war 部署在本地 WebSphere Liberty 服务器(版本 8.5.5.7)中，并且运行良好，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。我尝试通过两种方式推送本地应用程序。

选项 1

在这里，我将我的应用程序导出为与目标运行时作为IBM组下的WebSphere Liberty服务器的 war ，然后使用cf push <appname> -p <app.war>

这不会在上传时给我任何错误，但我无法使用给定的上下文根访问应用程序。

喜欢http://<appname>.mybluemix.net/<<root>>/login.jsp哪里<<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，但不能访问部署在蓝色混合。此处 Bluemix 无法找到 Web 应用程序的上下文。

选项 2

在这里，我点击下面的链接并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打包了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

上传实例后似乎崩溃并在日志中给出以下错误:

2015-10-15T13:58:29.10+0530 [API/0]      OUT App instance exited with guid 50ff6

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">
        <!-- <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 id="defaultHttpEndpoint" httpPort="9080" httpsPort="9443" />

</server>

你们能帮我解答一下我的问题吗？看来我缺少一些配置。任何帮助将不胜感激。

Answer 1

选项 1

是更简单的。我相信你的应该可以工作，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，Liberty buildpack 将在内部修改您的 war 文件。它将您的 war 文件重命名为 myapp.war 并将根上下文放入“/”中。

因此，根据您的情况，您应该能够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

比较复杂。我在本地运行了一个简单的测试，效果很好。

这是我所做的:

1. 我将 Java 应用程序从 Eclipse 部署到 Liberty 服务器的本地实例

2. 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

3. 上面的命令创建了 defaultServer.zip我将其复制到我的应用程序目录

4. 我运行以下命令来推送应用程序:

cf推送应用程序名称-p defaultServer.zip

一切正常，但这次我可以从原始根上下文访问我的应用程序，如下所示:

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

我从你的帖子中看到的主要区别是我的 server.xml包括 war 定义，但我没有web.xml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>
