CentOS自动安装jenkins

一、官网安装办法 https://pkg.jenkins.io/redhat-stable/

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
yum -y install jenkins

二、自动安装（包括清理旧版、开机启动、获取首次登录密码等，推荐）

安装：下载 jenkins.rar,按照readme操作即可

贴出shell文件：

#!/bin/sh

#关闭进程
killpids(){
  pids=($(ps -ef | grep $1 | awk '{print $2}'))
  for pid in ${pids[@]}; do
    echo "关闭进程: pid ${pid}"
    kill -9 ${pid}
  done
}
killpids jenkins

#uninstall old jenkins
old_jenkins=($(rpm -qa|grep jenkins))
for((i=0; i<${#old_jenkins[@]}; i++));do
  echo "旧版jenkins: ${old_jenkins[i]}"
  echo "删除..."
  yum -y remove jenkins ${old_jenkins[i]}
done

#删除
rm -rf /etc/logrotate.d/jenkins
rm -rf /etc/rc.d/init.d/jenkins
rm -rf /etc/sysconfig/jenkins
rm -rf /usr/lib/jenkins
rm -rf /var/log/jenkins
rm -rf /var/cache/jenkins
rm -rf /var/lib/jenkins
rm -rf /tmp/winstone/jenkins.war

#install jenkins
srcPath=$(find /usr/jenkins -maxdepth 1 -type f|grep '.*jenkins.*.rpm$')
if [[ $srcPath =~ "jenkins" ]]
  then
    echo "安装包：$srcPath"
	rpm -ivh $srcPath
  else
    sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
    sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
    yum -y install jenkins
fi

#修改端口号
sed -i 's/JENKINS_PORT=\"8080\"/JENKINS_PORT=\"8080\"/' /etc/sysconfig/jenkins

#启动并查看状态
service jenkins start
service jenkins status

#开机启动
echo ""
echo "开机启动"
chkconfig jenkins on

#修改端口号
echo "修改端口号: JENKINS_PORT="8080""

#显示版本
echo "version:"
rpm -qa|grep jenkins

#Administrator password(首次打开确认密码)
function getpassword(){
  spin=('.   ' '..  ' '... ' '....')
  cnt=0
  while(true)
  do
    ((cnt++))
    echo -n " wait${spin[$((cnt % 4))]}"
    echo -n -e \\r
    sleep 0.2
	if [[ $cnt -gt 180 ]]
	  then 
	    echo -e "\e[1;31mERROR:\e[0m Read Password Failure"
	    break
	fi
	if [ -f "/var/lib/jenkins/secrets/initialAdminPassword" ]
	  then
	    grep '' /var/lib/jenkins/secrets/initialAdminPassword
		break
    fi
	
  done  
    
}
echo "Administrator password(首次打开确认密码)："
getpassword
echo ""
