基于shell脚本实现的自动化部署（脚本）：

#!/bin/bash
echo "-------开始项目部署---------"
projectName="jmeterpush"
git_path="git@github.com:happyyangyanghappy/jmeterpush.git"

cd /home
echo "移除${projectName}项目源码"
rm -rf $projectName
sleep 3

echo "拉取${projectName}分支项目"
git clone ${git_path} ${projectName}
sleep 3

cd /home/${projectName}
echo "编译${projectName}项目"
mvn clean install
sleep 3

### 函数案例
killTomcat()
{
    #pid=`ps -ef|grep tomcat|grep java|awk '{print $2}'`
    #echo "tomcat Id list :$pid"
    #if [ "$pid" = "" ]
    #then
    #  echo "no tomcat pid alive"
    #else
    #  kill -9 $pid
    #fi
    #上面注释的或者下面的
    cd $TOMCAT_APP_PATH/bin
    sh shutdown.sh
}

# 停tomcat
echo "关闭tomcat"
killTomcat
sleep 3

# 删除原有工程
echo "删除tomcat原有工程"
rm -rf $TOMCAT_APP_PATH/webapps/${projectName}
#rm -f $TOMCAT_APP_PATH/webapps/ROOT.war
#rm -f $TOMCAT_APP_PATH/webapps/my-scrum.war
sleep 3

# 复制新的工程到tomcat上
echo "复制新的工程到tomcat上"
cp home/${projectName} $TOMCAT_APP_PATH/webapps/
sleep 3
 
echo "编译war包"
cd $TOMCAT_APP_PATH/webapps/
mv my-scrum.war ROOT.war
sleep 3
 
# 启动Tomcat
echo "启动Tomcat"
cd $TOMCAT_APP_PATH/
sh bin/startup.sh
sleep 3
