maven使用rpm-maven-plugin构建RPM包

rpm-maven-plugin 插件使用说明

1.web项目打rpm包

• 说明:
  
  1. mvn package -Dmaven.test.skip=true 打包生成rpm包
  2. 安装rpm包:将编译后代码安装指定的tomat目录下(tomcat_home配置)
  3. 卸载rpm包:自动清除已经安装的文件

1.1 在pom 文件添加插件配置

    <!-- 配置服务器上tomcat的安装根目录 
    <properties>
        <tomcat_home>/usr/soft/tomcat</tomcat_home>
    </properties>
    -->
    <!-- 打包RPM包 mvn package -Dmaven.test.skip=true   -->
    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>rpm-maven-plugin</artifactId>
        <version>2.1.5</version>
        <extensions>true</extensions>
        <executions>
            <execution>
                <goals>
                    <goal>rpm</goal>
                </goals>
            </execution>
        </executions>
        <configuration>
            <prefix>${tomcat_home}</prefix><!-- tomcat目录  -->
            <copyright>2018, wwww.myron.com</copyright>
            <distribution>myron</distribution>
            <group>myron.com</group>
            <packager>myron</packager>
            <version>${project.version}</version>
            <autoRequires>true</autoRequires>
            <release>3</release>
            <requires>
                <require>java-1.7.0 >= 1.7</require>
            </requires>
            <mappings>
                <mapping>
                    <!-- 安装rpm后指向的web安装目录   -->
                    <directory>${tomcat_home}/webapps/${project.artifactId}</directory>
                    <filemode>755</filemode>
                    <username>root</username>
                    <groupname>root</groupname>
                    <sources>
                        <source>
                            <location>target/${project.artifactId}-${project.version}</location>
                        </source>
                    </sources>
                </mapping>
            </mappings>
            <!-- rpm安装后执行的脚本-->
            <postinstallScriptlet>
                <script>echo "install success!"</script>
            </postinstallScriptlet>
        </configuration>
    </plugin>

1.2 linux中rpm-build的安装

yum install rpm-build

1.3 打包项目

mvn clean package -Dmaven.test.skip

1.4 rpm 安装与卸载

• rpm文件位置：target/rpm/demo-xxx/RPMS/noarch/demo-xxx.rpm

安装:
rpm -ivh demo-xxx.rpm
卸载:
rpm -e demo-xxx

1.5 启动/停止

安装后起停项目与普通tomcat的web项目一致

2.非web项目打rpm包(针对可执行jar包)

• 说明:
  
  1. 安装jar至服务器指定位置(其实就是复制jar)
  2. 配置软链接 注册服务 实现 systemctl start/stop/restart myapp 起停服务(linux 7)
  3. 安装相关脚本或插入服务相关脚本(根据实际需要)

1. pom文件补充下面配置

    <!--
    <properties>
        <java.version>1.8</java.version>
        <rpm.install.path>/usr/soft/app</rpm.install.path>
        <rpm.prefix>/usr/soft/app</rpm.prefix>
    </properties>
    -->
<build>
    <plugins>
        <!-- 打包RPM包: mvn package -Dmaven.test.skip=true   -->
