**一、安装Jenkins**

1.  安装JDK环境

源码安装jdk1.8及以上版本，环境变量vim /etc/profile写在最后面如下：

export JAVA\_HOME=/usr/local/jdk1.8.0\_144

export JRE\_HOME=/usr/local/jdk1.8.0\_144/jre

export CLASSPATH=.:$JAVA\_HOME/lib:$JRE\_HOME/lib:$CLASSPATH

export PATH=$JAVA\_HOME/bin:$JRE\_HOME/bin:$SCRIPT\_HOME:$PATH

我配置的jdk版本就是1.8的

1.  下载Jenkins

我这里选择下载war包进行安装，自我感觉非常的简单易操作！

官网下载：[https://jenkins.io/index.html][https_jenkins.io_index.html]

我这里下载的版本是2.112

1.  安装Tomcat

下载地址：[http://mirrors.hust.edu.cn/apache/tomcat][http_mirrors.hust.edu.cn_apache_tomcat]

我安装的版本是tomcat8，把之前的jenkins.war拷到webapps下，启动tomcat。我用的8080端口访问地址为[http://IP:8080/jenkins][http_IP_8080_jenkins]

\#\#\#\#安装上面的提示查看密码，输入密码

![70 1][]

\#\#\#\#\#\#我选择第一个，第二个也可以这样装的包少一点。安装的插件都在/root/.jenkins/plugins/下

![70 2][]

\#\#\#\#\#\#开始安装插件

![70 3][]

![70 4][]

![70 5][]

\#\#\#\#\#\#\#至此jenkins安装完毕！

**二、安装Maven（用来构建项目）**

官网地址：[http://maven.apache.org/download.cgi][http_maven.apache.org_download.cgi]

我安装的是Apache Maven 3.2.5

配置环境变量：vim /etc/profile 写到最后

MAVEN\_HOME=/usr/local/apache-maven-3.2.5

export MAVEN\_HOME

export PATH=$\{PATH\}:$\{MAVEN\_HOME\}/bin

**三、安装git（用来取gitlab上的代码）**

下载地址：[https://github.com/git/git/releases][https_github.com_git_git_releases]

我安装的版本是git-2.3.0

配置环境变量：vim /etc/profile 写到最后

export PATH=/usr/local/git/bin:$PATH

**四、配置Jenkins**

![70 6][]

![70 7][]

![70 8][]

![70 9][]

选择可选插件进行搜索安装插件有

Git plugin

SSH Plugin

Maven integration Plugin

Deploy to Container Plugin

**五、构建项目**

点击新建任务 起一个test名字 选择构建一个maven项目

\#\#\#\#\#\#如果没做以下操作肯定会报错的

![70 12][]

\#\#\#\#\#\#这块填写gitlab的私钥！！！完成之后如下图

![70 13][]

![70 14][]

![70 15][]

\#\#\#看一下我的脚本内容：

\[root@2015hk1 ~\]\# cat /opt/web.sh

\#!/bin/bash

source /etc/profile

TOMCAT\_HOME=/data/server/tomcat-gw/webapps

JENKINS\_HOME=/root/.jenkins/workspace/yilucaifu-open/yilucaifu-web/target

DATE=$(date +%Y-%m-%d\_%H:%M)

mv $TOMCAT\_HOME/yilucaifu /data/back-web/yilucaifu.$DATE

scp -r 60.60.1.222:$JENKINS\_HOME/yilucaifu.war $TOMCAT\_HOME

unzip -d $TOMCAT\_HOME/yilucaifu $TOMCAT\_HOME/yilucaifu.war

\#\\cp -f /opt/web\_web.xml/web.xml $TOMCAT\_HOME/yilucaifu/WEB-INF

\\cp -f /opt/web\_jdbc/jdbc-context.xml $TOMCAT\_HOME/yilucaifu/WEB-INF/conf

rm -rf $TOMCAT\_HOME/\*.war

/data/script/tomcat\_gw.sh restart

\[root@2015hk1 ~\]\# cat /data/script/tomcat\_gw.sh

\#!/bin/bash

TOMCAT\_HOME=/data/server/tomcat-gw

DATE=$(date +%F)

pid=\`ps aux | grep tomcat-gw | grep -v grep | awk '\{print $2\}'\`

str=$"\\n"

sstr=$(echo -e $str)

if \[ $\# -ne 1 \];then

echo "Usage: $0 \{start|stop|restart\}"

exit 1

case $1 in

start)

$TOMCAT\_HOME/bin/catalina.sh start

tail -f $TOMCAT\_HOME/logs/catalina."$DATE".out &

TAIL\_PID=$(ps aux | grep "tail -f $TOMCAT\_HOME/logs/catalina."$DATE".out" | grep -v grep | awk '\{print $2\}')

echo "TAIL\_PID is $TAIL\_PID"

sleep 25 && kill -9 $TAIL\_PID &

sleep 30 && echo "$sstr"

;;

stop)

echo "pid= $pid"

echo "now kill tomcat pid $pid"

kill -9 $pid

if \[ $? -eq 0 \];then

echo "Tomcat has stopped"

;;

restart)

echo "pid= $pid"

echo "now kill tomcat pid $pid"

kill -9 $pid

$TOMCAT\_HOME/bin/catalina.sh start

sleep 1

tail -f $TOMCAT\_HOME/logs/catalina."$DATE".out &

TAIL\_PID=$(ps aux | grep "tail -f $TOMCAT\_HOME/logs/catalina."$DATE".out" | grep -v grep | awk '\{print $2\}')

echo "TAIL\_PID is $TAIL\_PID"

sleep 25 && kill -9 $TAIL\_PID &

sleep 30 && echo "$sstr"

echo -e "\\033\[32m Continue to check the log,please execute the command: \\033\[0m"

echo -e "\\033\[32m tail -f $TOMCAT\_HOME/logs/catalina."$DATE".out \\033\[0m"

;;

\*)

echo "Usage: $0 \{start|stop|restart\}"

exit 1

;;

esac

Jenkins和 60.60.1.223互做了免密登录，在jenkins上可以直接用/usr/bin/ssh root@60.60.1.223要执行的命令" /opt/web.sh 在60.60.1.223上执行这个脚本

过程：jenkins调用git把Gitlab上的代码下载到jenkins服务器，maven构建成war包，调用ssh运行shell脚本完成备份，停服务，清webapps，拷war包到tomcat下，起服务，ok！
