Linux下Jenkins的安装和启动(war包)

1.下载Jenkins war包

• Jenkins jar 下载
• 或者使用在线地址下载如下

wget http://mirrors.jenkins-ci.org/war/latest/jenkins.war

　　备注：若下载速度很慢，可以在windows下进行下载，然后放到linux里，再直接运行就行了。我当前放到/opt下的

2.启动war包命令----2种方式使用任意一种就行

　　1.命令启动方式：

java –jar Jenkins.war --httpPort=9000

• 　　httpPort表示配置指定Jenkins端口，由于Jenkins默认端口是8080，通常8080端口可能会有占用情况，所以换成自己定义的端口9000，备注:若更换的端口没有开放，如何开放端口的操作，请阅读 'linux-cenots7下开放某个端口'

　　2.脚本启动方式：

• 　　创建jenkins.sh脚本文件，并复制以下脚本

#!/bin/bash
JAVA_OPTIONS="-server -Xmx256m -Xms256m"
Jenkins=$2
this_dir="$( cd "$( dirname "$0" )" && pwd )"
log_file="${this_dir}/catalina.out"
jar_file="${this_dir}/${Jenkins}"

if [ "$1" = "" ];
then
echo -e "\033[0;31m 未输入操作名 \033[0m \033[0;34m {start|stop|restart|status} \033[0m"
exit 1
fi

if [ "$Jenkins" = "" ];
then
echo -e "\033[0;31m 未输入应用名 \033[0m"
exit 1
fi

function start()
{
count=`ps -ef |grep java|grep $Jenkins|grep -v grep|wc -l`
if [ $count != 0 ];then
echo "$Jenkins is running..."
else
nohup java $JAVA_OPTIONS -jar ${jar_file} --httpPort=9000 > "${log_file}" 2>&1 &
echo -e "Start $Jenkins success...Please see the detail log in /logs/catalina.out"
fi
}

function stop()
{
echo "Stop $Jenkins"
boot_id=`ps -ef |grep java|grep $Jenkins|grep -v grep|awk '{print $2}'`
count=`ps -ef |grep java|grep $Jenkins|grep -v grep|wc -l`

if [ $count != 0 ];then
kill $boot_id
count=`ps -ef |grep java|grep $Jenkins|grep -v grep|wc -l`

boot_id=`ps -ef |grep java|grep $Jenkins|grep -v grep|awk '{print $2}'`
kill -9 $boot_id
fi
}

function restart()
{
stop
sleep 2
start
}

function status()
{
count=`ps -ef |grep java|grep $Jenkins|grep -v grep|wc -l`
if [ $count != 0 ];then
echo "$Jenkins is running..."
else
echo "$Jenkins is not running..."
fi
}

case $1 in
start)
start;;
stop)
stop;;
restart)
restart;;
status)
status;;
*)

echo -e "\033[0;31m Usage: \033[0m \033[0;34m sh $0 {start|stop|restart|status} {JenkinsJarName} \033[0m
\033[0;31m Example: \033[0m
\033[0;33m sh $0 start esmart-test.jar \033[0m"
esac

3.启动jenkins相关命令

• 对jenkins.sh文件增加执行权限

# chmod u+x jenkins.sh

• 启动Jenkins

# ./jenkins.sh start jenkins.war

• 停止Jenkins

# ./jenkins.sh stop jenkins.war

• 重启Jenkins

# ./jenkins.sh restart jenkins.war

• 查看Jenkins状态

# ./jenkins.sh status jenkins.war
