gitlab+jenkins实现项目自动部署

1 实现效果

向gitlab代码仓库提交代码后，Jenkins自动构建，并自动部署项目

2 Jenkins任务配置如下

里边写的内容是

BUILD_ID=DONTKILLME
/tmp/autodeploy.sh

3. 脚本内容

#!/bin/bash
#定义变量
START="/usr/local/tomcat/bin/startup.sh"
STOP="/usr/local/tomcat/bin/shutdown.sh"
DIR=`date +%Y%m%d%H%M%S`
DEST="/tmp/$DIR"
APPBASE=/usr/local/tomcat/webapps/ROOT/
WARDEST=/tmp
WARFILE="http://JENKINS_URL/job/kgcweb/lastSuccessfulBuild/artifact/target/kgcweb.war"

###backup### 备份原来Tomcat项目的文件
mkdir -p $DEST
mv $APPBASE/* $DEST

###fetch war file###  获取项目war包
wget -O $WARDEST/kgcweb.war -c $WARFILE

###deploy war file###  部署war包
unzip $WARDEST/kgcweb.war -d $APPBASE
$STOP
$START

4 jenkins主机的准备

jenkins主机：
[root@localhost ~]# chmod -R 777 /usr/local/tomcat/
不执行这步，解压就没有权限，因为Jenkins用户也是普通用户

如果最后部署成功就OK，如果最后部署成功了，但是访问的时候页面报500的错误，需要更改一下Tomcat安装目录的属主和属组

[root@localhost ~]# chown -R jenkins:jenkins /usr/local/tomcat/
