springcloud基于jenkins自动部署

jenkins运行流程：

1、从SVN拉取代码到 jenkins

2、运行maven命令clean install，将项目打 jar (war)包

3、执行shell 脚本，启动项目

下图是我们的项目

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2thbmc1Nzg5_size_16_color_FFFFFF_t_70][]

两部分：红色是需要运行的项目、绿色是基础项目不需要运行（只需deploy到maven仓库即可）

jenkins下载：[http://mirrors.jenkins.io/war-stable/][http_mirrors.jenkins.io_war-stable]

1、修改tomcat 字符编码

vi jenkins-tomcat/conf/server.xml

将下载的 jenkins.war 放到 tomcat，启动，插件默认安装即可

2、系统设置，配置jdk  maven

先同步下系统时间

1.删除自带的 localtime

rm -rf /etc/localtime

2.创建软链接到 localtime

ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

yum install -y ntpdate

ntpdate ntp1.aliyun.com

3、安装插件

安装完成重启jenkins  ：  [http://192.168.33.12:8088/jenkins/restart][http_192.168.33.12_8088_jenkins_restart]

4、新建项目

添加maven命令，也就是对源码进行打包，clean install -Dmaven.test.skip=true

![20181221154119370.png][]

5、构建项目

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2thbmc1Nzg5_size_16_color_FFFFFF_t_70 5][]

构建完的项目地址在  /root/.jenkins/workspace/xxxxx/target

![20181221154440502.png][]

6、编写shell脚本，启动构建好的jar

首先在系统设置里配置一下publish over ssh ，这里的地址就是我们即将部署的机器，因为jenkins很可能和部署的机器不是一台

注意 Remote Directory参数代表用户的根目录

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2thbmc1Nzg5_size_16_color_FFFFFF_t_70 6][]

保存，继续配置项目

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2thbmc1Nzg5_size_16_color_FFFFFF_t_70 7][]

选择我们刚才配置的机器，参数解释

Source files：jenkins打完包的地址，参考第5步，从target开始写

Remove prefix：前缀写target，标识从那个文件夹开始

Remote directory：要拷贝到的远程服务器，不需要写用户根目录，比如/usr/local/apps/xxx 只需写apps/xxx即可

Exec command：执行的脚本地址，就是启动项目脚本，内容如下

#!/bin/sh
    
    ## java env
    export JAVA_HOME=/usr/local/java
    export JRE_HOME=$JAVA_HOME/jre
    
    ## service name
    APP_NAME=eureka
    SERVICE_DIR=/usr/local/apps/$APP_NAME
    SERVICE_NAME=com.jk.cloud.$APP_NAME-0.0.1-SNAPSHOT
    
    JAR_NAME=$SERVICE_NAME\.jar
    PID=$SERVICE_NAME\.pid
    
    cd $SERVICE_DIR
    
    case "$1" in
    
        start)
            nohup $JRE_HOME/bin/java -Xms256m -Xmx512m -jar $JAR_NAME >log.out 2>&1 &
            echo $! > $SERVICE_DIR/$PID
            echo "=== start $SERVICE_NAME"
            sleep 10
            cat -fn3000 log.out
            ;;
    
        stop)
            kill `cat $SERVICE_DIR/$PID`
            rm -rf $SERVICE_DIR/$PID
            echo "=== stop $SERVICE_NAME"
    
            sleep 5
            P_ID=`ps -ef | grep -w "$SERVICE_NAME" | grep -v "grep" | awk '{print $2}'`
            if [ "$P_ID" == "" ]; then
                echo "=== $SERVICE_NAME process not exists or stop success"
            else
                echo "=== $SERVICE_NAME process pid is:$P_ID"
                echo "=== begin kill $SERVICE_NAME process, pid is:$P_ID"
                kill -9 $P_ID
            fi
            ;;
    
        restart)
            $0 stop
            sleep 2
            $0 start
            echo "=== restart $SERVICE_NAME"
            ;;
    
        *)
            ## restart
            $0 stop
            sleep 2
            $0 start
            ;;
    esac
    exit 0

保存，再次构建，大功告成！！！

示例脚本：

echo "Stopping SpringBoot Application "
    pid=`ps -ef | grep demo.jar | grep -v grep | awk '{print $2}'`
    if [ -n "$pid" ]
    then
       kill -9 $pid
    fi
    rm -rf /opt/apps/demo*
    cp -f /root/.jenkins/workspace/.../target/demo.jar /opt/apps/
    cd /opt/apps
    chmod 777 /opt/apps/demo.jar
    BUILD_ID=DONTKILLME
     
    nohup java -Xms256m -Xmx512m -jar demo.jar >demo.log 2>&1 &
    echo "################ build success ###################"

遇到的问题：

在基础项目打包的时候需要修改pom.xml的打包方式，打成普通jar即可

<distributionManagement>
    		<repository>
    			<id>nexus-releases</id>
    			<url>http://10.90.189.109:8081/nexus/content/repositories/releases</url>
    		</repository>
    		<snapshotRepository>
    			<id>nexus-snapshots</id>
    			<url>http://10.90.189.109:8081/nexus/content/repositories/snapshots</url>
    		</snapshotRepository>
    	</distributionManagement>

而需要启动的springcloud项目，则使用springboot 自带的打包插件

<build>
    	<resources>
    	            <resource>
    	                <directory>${basedir}/src/main/webapp</directory>
                        
    	                <targetPath>META-INF/resources</targetPath> 
    	                <includes>
    	                    <include>**/**</include>
    	                </includes>
    	            </resource>
    	            <resource>
    	                <directory>${basedir}/src/main/resources</directory>
