分分鐘讓你學會Jenkins自動化部署SpringBoot項目

1、安裝jenkins，在jenkins上安裝jdk、git、maven就不說了，這些網上一大把。

    jenkins免密登錄到其他服務器可以參考我這一篇：jenkins免密登錄到其他服務器

2、看下項目中的配置，按照我的目錄結構創建這2個文件和文件夾

assembly.xml文件中的內容，是爲了方便打包成zip格式的，而zip中包含了jar、bin、lib，如下：

<assembly 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/assembly-1.0.0.xsd">
	<id>bin</id>
	<formats>
		<format>zip</format>
	</formats>
	<includeBaseDirectory>true</includeBaseDirectory>
	<fileSets>
		<fileSet>
			<directory>${project.basedir}</directory>
			<outputDirectory>./</outputDirectory>
			<includes>
				<include>README*</include>
				<include>LICENSE*</include>
				<include>NOTICE*</include>
			</includes>
		</fileSet>
		<fileSet>
			<directory>target/config</directory>
			<outputDirectory>config</outputDirectory>
			<includes>
				<include>**/*</include>
				<include>*.xml</include>
				<include>*.properties</include>
				<include>*.yml</include>
			</includes>
		</fileSet>
		<fileSet>
			<directory>target/classes</directory>
			<outputDirectory>classes</outputDirectory>
		</fileSet>
		<fileSet>
			<directory>target/lib</directory>
			<outputDirectory>lib</outputDirectory>
		</fileSet>
		<fileSet>
			<directory>bin</directory>
			<outputDirectory>bin</outputDirectory>
			<includes>
				<include>startup.*</include>
			</includes>
			<filtered>true</filtered>
		</fileSet>
		<fileSet>
			<directory>target</directory>
			<outputDirectory>./</outputDirectory>
			<includes>
				<include>*.jar</include>
			</includes>
			<excludes>
				<exclude>*sources.jar</exclude>
			</excludes>
		</fileSet>
	</fileSets>
</assembly>

 startup.sh是一個啓動腳本，裏面的一些jvm參數可以根據自身項目進行修改，內容如下：

basepath=$(cd `dirname $0`; pwd)
java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8888  -Duser.timezone=Asia/Shanghai -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -server -Xmx${jvm.Xmx} -Xms${jvm.Xms} -Xmn${jvm.Xmn} -Xss${jvm.Xss} -XX:MetaspaceSize=128m -XX:+DisableExplicitGC -XX:+UseParNewGC -XX:ParallelGCThreads=4 -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:+UseCMSCompactAtFullCollection -XX:LargePageSizeInBytes=128m -XX:+UseFastAccessorMethods -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=75 -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintTenuringDistribution -XX:+PrintGCApplicationStoppedTime -Xloggc:/logs/jvm/gc.log -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=32 -XX:GCLogFileSize=64m -XX:ErrorFile=/logs/jvm/youxuan-web-error_%p.log -jar ../youxuan-web.jar --spring.profiles.active=${profiles.active}

對於裏面一些應用，如${jvm.Xms}等，是根據如下來引用的，把下面的配置放在web中的xml下，至於啓用那個環境的，根據jenkins中maven啓動命令來

<profiles>
        <profile>
            <id>prod</id>
            <properties>
                <profiles.active>prod</profiles.active>
                <jvm.Xmx>2560m</jvm.Xmx>
                <jvm.Xms>2560m</jvm.Xms>
                <jvm.Xmn>1024m</jvm.Xmn>
                <jvm.Xss>256k</jvm.Xss>
                <jvm.permsize>128m</jvm.permsize>
                <log.home.dir>${user.dir}/logs</log.home.dir>
                <libScope>compile</libScope>
            </properties>
        </profile>
        <profile>
            <id>test</id>
            <properties>
                <profiles.active>test</profiles.active>
                <jvm.Xmx>1024m</jvm.Xmx>
                <jvm.Xms>1024m</jvm.Xms>
                <jvm.Xmn>512m</jvm.Xmn>
                <jvm.Xss>256k</jvm.Xss>
                <jvm.permsize>128m</jvm.permsize>
                <log.home.dir>${user.dir}/logs</log.home.dir>
                <libScope>compile</libScope>
            </properties>
        </profile>
        <profile>
            <id>dev</id>
            <properties>
                <profiles.active>dev</profiles.active>
                <jvm.Xmx>512m</jvm.Xmx>
                <jvm.Xms>512m</jvm.Xms>
                <jvm.Xmn>192m</jvm.Xmn>
                <jvm.Xss>256k</jvm.Xss>
                <jvm.permsize>64m</jvm.permsize>
                <log.home.dir>${user.dir}/logs</log.home.dir>
                <libScope>compile</libScope>
            </properties>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>
    </profiles>

下面的配置也必不可少，同樣放在web中的xml下，跟上面那個配置放在一個位置

3、創建一個流水線類型的項目，按照參數化構建的過程添加參數：

 git地址：

maven構建命令 ,其中其他命令就不介紹了，介紹下 -P test

-P test 代表引用剛纔pom.xml中<profiles.active>test</profiles.active>

這個配置，相當於指定了環境爲test

 shell腳本，真正的打包命令

pid=`ssh ${server} /opt/jdk1.8.0_161/bin/jps | grep ${project} | awk '{print $1}'`
ssh ${server} kill -9 $pid || echo "no java process"

rsync -avz --delete ${WORKSPACE}/${project}-server/target/${project}-server-bin.zip  ${server}:/xxx/service

ssh ${server} << EOF
rm -rf /xxx/service/${project}-server/
unzip /xxx/service/${project}-server-bin.zip  -d /qinwell/service
cd /qinwell/service/${project}-server
chmod 664 *.jar
cd /qinwell/service/${project}-server/bin/
chmod +x startup.sh
nohup ./startup.sh >/dev/null 2>&1 &
EOF

介紹下，上面主要幹嘛的，先殺死原來的進程，遠程數據同步，刪除之前的項目，解壓，賦予.jar執行權限，執行項目中的腳本。

最後來個總結：

上面的配置，是我在生產中使用，按照如上配置，絕壁沒問題呀，感覺幫助了你，點個贊再走吧，麼麼噠
