jenkins自动化部署

1.官网下载jenkins包

2.使用脚本启动jenkins----restrtJenkins.sh脚本内容如下

#!/bin/bash

PID=`ps -ef | grep 'jenkins.war' | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
  echo "killing jenkins : $PID"
  kill $PID
fi

sleep 1

LOGS_DIR=/home/heqs/yx/jenkins/logs

MAIN_JAR="-jar ./jenkins/jenkins.war --httpPort=8568 "
JAVA_ARGS="-server -Xms2048m -Xmx2048m -XX:NewSize=1500m -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=70 -XX:+PrintGCDetails -XX:+PrintHeapAtGC  -XX:ThreadStackSize=512 -Xloggc:${LOGS_DIR}/gc.log "

nohup java ${JAVA_ARGS} ${MAIN_JAR} 1>>${LOGS_DIR}/stdout.log 2>>${LOGS_DIR}/stderr.log &
echo "startup jenkins ..."

3.遇到问题就是

参考链接：https://www.pianshen.com/article/8569310067/

[root@local heqs]# telnet 192.168.122.1 8568
Trying 192.168.122.1...
Connected to 192.168.122.1.
Escape character is '^]'.
Connection closed by foreign host.

试了网上那些关闭蓝灯呀，关闭防火墙呀都没啥用，最后是采用了以下的方法：
首先：开启 web 端口
firewall-cmd --permanent --add-port=80/tcp
重启 firewall
firewall-cmd --reload

 至此启动jenkins成功

3.打开之后需要输入用户名密码，默认用户名是admin,密码在 /root/.jenkins/secrets/initialAdminPassword，输入之后登录成功
