1. 准备好最新的jenkins.war和配置文件如下：

#!/bin/bash

# 导入环境变量

export JENKINS_HOME=/home/jenkins

export JAVA_HOME=/home/java/jdk1.8.0_191

cd $JENKINS_HOME

pid=`ps -ef | grep jenkins.war | grep -v 'grep'| awk '{print $2}'`

if [ "$1" = "start" ];then

if [ -n "$pid" ];then

echo 'jenkins is running...'

else

### java启动服务 配置java安装根路径,和启动war包存的根路径

nohup $JAVA_HOME/bin/java -Xms512m -Xmx768m -jar $jenkins_HOME/jenkins.war --ajp13Port=-1 --httpPort=8801 >/dev/null 2>&1 &

fi

elif [ "$1" = "stop" ];then

exec ps -ef | grep jenkins | grep -v grep | awk '{print $2}'| xargs kill -9

echo 'jenkins is stop...'

else

echo "Please input like this:"./jenkins.sh start" or "./jenkins stop""

fi

2.开启防火墙

firewall-cmd --zone=public --add-port=8801/tcp --permanent

firewall-cmd --reload

firewall-cmd --list-ports

yum update

Docker安装官方地址：https://docs.docker.com/install/linux/docker-ce/centos/

以下命令都是在root账号权限下执行的

yum install -y yum-utils device-mapper-persistent-data lvm2

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

安装最新版本的Docker CE和containerd

yum install docker-ce docker-ce-cli containerd.io

启动Docker

systemctl start docker

ip addr查看docker是否成功安装

启动docker命令

systemctl start docker.service

设置开机启动docker

systemctl enable docker

修改镜像地址

vi /etc/docker/daemon.json

docker pull nginx

docker pull tomcat:8.5

1. 启动 nginx容器

docker run -d -p 80:80 --restart=always -v /home/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /home/nginx/logs:/var/log/nginx --name nginx nginx

nginx.conf 配置文件

2.开启防火墙

firewall-cmd --zone=public --add-port=80/tcp --permanent

firewall-cmd --reload

firewall-cmd --list-ports
