如何实现Web服务的持续部署

Question

我有一个Java应用程序,它在Web容器(Jetty目前)内运行,并通过Web服务响应请求.

现在我想创建一个机制,允许尽可能容易地部署(将WAR文件传输到服务器,在那里安装新版本)应用程序的新版本到达Amazon EC2实例(理想情况下 - 通过运行一些Maven命令) .

我正在使用Beanstalk进行版本控制,它们提供了部署支持,但我无法弄清楚如何将其应用到我的场景中.

有没有关于如何使用Maven(有或没有Beanstalk)将Web应用程序部署到Amazon EC2的教程？

更新1(10.04.2013): Beanstalk工作人员建议我使用SSH部署.

更新2(2013年4月11日23:17 MSK):

在我第一次尝试使用Maven Cargo插件时,我向我添加了以下内容pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    [...]
    <build>
    [...]    
            <plugin>
                <groupId>org.codehaus.cargo</groupId>
                <artifactId>cargo-maven2-plugin</artifactId>
                <configuration>
                    <container>
                        <containerId>Heaven7</containerId>
                        <type>remote</type>
                    </container>
                    <configuration>
                        <type>runtime</type>
                        <properties>
                            <cargo.remote.username>myusername</cargo.remote.username>
                            <cargo.remote.password>mypassword</cargo.remote.password>
                        </properties>
                    </configuration>

                    <!-- Deployer configuration -->
                    <deployer>
                        <type>remote</type>
                    </deployer>

                    <deployables>
                        <deployable>
                            <groupId>ru.mycompany</groupId>
                            <artifactId>my-product</artifactId>
                            <type>war</type>
                        </deployable>
                    </deployables>
                </configuration>
            </plugin>
        </plugins>
    </build>
    [...]
</project>

然后我跑了mvn cargo:deploy并获得了以下输出:

[ERROR] Failed to execute goal org.codehaus.cargo:cargo-maven2-plugin:1.3.3:dep
oy (default-cli) on project [...]: Execution default-cli of goal org.codeh
us.cargo:cargo-maven2-plugin:1.3.3:deploy failed: Cannot create configuration.
here's no registered configuration for the parameters (container [id = [Heaven7
, type = [remote]], configuration type [runtime]). Actually there are no valid
ypes registered for this configuration. Maybe you've made a mistake spelling it

2个问题:

1. 我该如何解决？
2. 我在哪里可以指定我的Tomcat容器的地址？

更新3(12.04.2013 22:36 MSK):

我更改了与Cargo插件相关的部分,如下所示:

    <plugin>
        <groupId>org.codehaus.cargo</groupId>
        <artifactId>cargo-maven2-plugin</artifactId>
        <version>1.3.3</version>
        <configuration>
            <container>
                <containerId>tomcat7</containerId>
                <type>remote</type>
            </container>
            <configuration>
                <type>runtime</type>
                <properties>
                    <cargo.remote.username>myuser</cargo.remote.username>
                    <cargo.remote.password>mypassword</cargo.remote.password>
                    <cargo.hostname>ec2-NN-NNN-NN-NN.compute-1.amazonaws.com</cargo.hostname>
                    <cargo.protocol>http</cargo.protocol>
                    <cargo.servlet.port>8080</cargo.servlet.port>
                </properties>
            </configuration>

            <!-- Deployer configuration -->
            <deployer>
                <type>remote</type>
            </deployer>
            <deployables>
                <deployable>
                    <groupId>ru.mycompany</groupId>
                    <artifactId>myproduct</artifactId>
                    <type>war</type>
                </deployable>
            </deployables>

        </configuration>
    </plugin>
</plugins>

然后我执行mvn cargo:deploy并得到了这个输出:

[ERROR] Failed to execute goal org.codehaus.cargo:cargo-maven2-plugin:1.3.3:depl
oyer-deploy (default-cli) on project ccp-server: Execution default-cli of goal o

ere are no valid types registered for this configuration. Maybe you've made a mi
stake spelling it? -> [Help 1]

更新4(12.04.2013 23:12):

我pom.xml再次改为:

<plugin>
    <groupId>org.codehaus.cargo</groupId>
    <artifactId>cargo-maven2-plugin</artifactId>
    <version>1.3.3</version>
    <configuration>
        <container>
            <containerId>tomcat7x</containerId>
            <type>remote</type>
        </container>
        <configuration>
            <type>runtime</type>
            <properties>
                <cargo.remote.username>myuser</cargo.remote.username>
                <cargo.remote.password>mypassword</cargo.remote.password>
                <cargo.hostname>ec2-NN-NNN-NN-NN.compute-1.amazonaws.com</cargo.hostname>
                <cargo.protocol>http</cargo.protocol>
                <cargo.servlet.port>8080</cargo.servlet.port>
            </properties>
        </configuration>

        <!-- Deployer configuration -->
        <deployer>
            <type>remote</type>
        </deployer>
        <deployables>
            <deployable>
                <groupId>ru.mycompany</groupId>
                <artifactId>myproduct</artifactId>
                <type>war</type>
            </deployable>
        </deployables>

    </configuration>
</plugin>

然后,我使用以下命令将我的应用程序部署到服务器:

1. mvn clean
2. mvn install
3. mvn cargo:deploy

请注意,<packaging>必须设置war为此顺序才能正常工作(否则您可能会收到奇怪的错误消息).

Answer 1

如果我错了，请纠正我。我了解到您正在使用Tomcat version 7. 配置Cargo应Tomcat 7如下所示：-

<plugin>
    <groupId>org.codehaus.cargo</groupId>
    <artifactId>cargo-maven2-plugin</artifactId>
    <version>1.3.3</version>
    <configuration>
        <container>
            <containerId>tomcat7x</containerId>
            <type>remote</type>
        </container>
        <configuration>
            <type>runtime</type>
            <properties>
                <cargo.remote.username>myusername</cargo.remote.username>
                <cargo.remote.password>mypassword</cargo.remote.password>
                <cargo.hostname>MY_HOST</cargo.hostname>
                <cargo.protocol>http</cargo.protocol>
                <cargo.servlet.port>SERVER_PORT</cargo.servlet.port>
            </properties>
        </configuration>
        <!-- Deployer configuration -->
        <deployer>
            <type>remote</type>
            <deployables>
                <deployable>
                    <groupId>ru.mycompany</groupId>
                    <artifactId>my-product</artifactId>
                    <type>war</type>
                    <properties>
                        <context>MY_CONTEXT</context>
                    </properties>
                </deployable>
            </deployables>
        </deployer>
    </configuration>
</plugin>

请注意

1. <cargo.hostname>是远程主机名或 IP 地址。
2. <cargo.protocol>是http或https。
3. <cargo.servlet.port>是remote port基于的<cargo.protocol>，例如8080或8443
4. <context>是context name部署 Web 应用程序时使用的。

请参阅Cargo：Tomcat 7.x和Maven2 插件参考指南以获取更多信息。

我希望这会有所帮助。
