脚本安装Dockerfile安装Jenkins
#1.编写Docker安装脚本 [root@ip-10-0-12-212 ~]# vim Ins_Docker.sh #!/usr/bin/bash # Author:wl # Time:2023-06-09 11:54:22 # Name:Ins_Docker.sh # Version: 1.0 # Discription: To source /etc/init.d/functions rely_software=(yum-utils device-mapper-persistent-data lvm2) echo "-----------------#1.检测系统内核版本-----------------" kernel_version=`uname -a |awk '{print $3}'|cut -d. -f1` [ $kernel_version -ge 3 ] && action "The System Install Docker is ..." /usr/bin/true || action "The System Can not Install Docker is ..." /usr/bin/false;exit echo "-----------------#2.安装Docker依赖软件-----------------" for i in ${rely_software[*]} do rpm -q $i &>/dev/null if [ $? -eq 0 ];then echo "$i is installed" else yum -y install $i &>/dev/null action "$i is installing" /usr/bin/true fi done echo "-----------------#3.添加Docker镜像源-----------------" yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo [ $? -eq 0 ] && action "Docker Image add is ..." /usr/bin/true || echo "Docker Image add is ..." /usr/bin/false;exit echo "-----------------#4.安装Docker-----------------" yum -y install docker-ce rpm -qa |grep docker-ce [ $? -eq 0 ] && action "Docker-ce is installed ..." /usr/bin/true || action "Docker-ce is install ..." /usr/bin/false;exit echo "-----------------#5.启动Docker并设置开机自启-----------------" systemctl enable --now docker [ $? -eq 0 ] && action "Docker Start is ...;" /usr/bin/true || action "Docker start is ..." /usr/bin/false docker_version=`docker -v |awk -F ',' '{print $1}'` echo "-----------------#6.设置Docker加速器-----------------" sudo mkdir -p /etc/docker sudo cat >/etc/docker/daemon.json <<EOF { "registry-mirrors": ["https://8mh75mhz.mirror.aliyuncs.com"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker echo "-----------------#7.查看Docker是否安装完成-----------------" cat << EOF +-------------------------------------------------+ | $docker_version 安 装 已 完 成 | | 请 使 用 相 关 服 务 ! | +-------------------------------------------------+ EOF echo "-----------------#8.迁移Docker根目录-----------------" systemctl stop docker mv /var/lib/docker/ /data/ sed -i 's#ExecStart=/usr/bin/dockerd#ExecStart=/usr/bin/dockerd --graph=/data/docker#g' /usr/lib/systemd/system/docker.service systemctl daemon-reload systemctl start docker.service echo "-----------------#9.验证Docker根目录是否生效-----------------" docker info |grep "Docker Root Dir" sleep 5 echo ""-----------------你的小可爱已完成Docker全部部署-----------------"
#2.给脚本添加执行权限 [root@ip-10-0-12-212 ~]# chmod +x Ins_Docker.sh #3.执行脚本 [root@ip-10-0-12-212 ~]# sh Ins_Docker.sh
二、编写Dockerfile
epel下载地址：http://mirrors.sohu.com/fedora-epel/
jdk下载：https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html
Jenkins下载：https://mirrors.tuna.tsinghua.edu.cn/jenkins/redhat-stable/
2.249版本下载：https://pkg.jenkins.io/redhat-stable/jenkins-2.249.3-1.1.noarch.rpm
#1.创建Dockerfile存放目录 [root@ip-10-0-12-212 ~]# mkdir jenkins [root@ip-10-0-12-212 ~]# cd jenkins #2.编写Dockerfile [root@ip-10-0-12-212 jenkins]# vim Dockerfile #Is my first jenkins Dockerfile # Version 1.0 # Base images 基础镜像 FROM centos:7 #MAINTAINER 维护者信息 MAINTAINER Jin.Hui #ADD 文件放在当前目录下，拷过去会自动解压 ADD jdk-8u131-linux-x64.tar.gz /opt/ COPY epel-release-latest-7.noarch.rpm /opt/ COPY jenkins-2.249.3-1.1.noarch.rpm /opt/ #RUN 执行以下命令 RUN rpm -ivh /opt/epel-release-latest-7.noarch.rpm \ && rpm -ivh /opt/jenkins-2.249.3-1.1.noarch.rpm \ && ln -s /opt/jdk1.8.0_131 /opt/jdk COPY jenkins /etc/sysconfig/jenkins #ENV 设置环境变量 ENV JAVA_HOME /opt/jdk ENV PATH $JAVA_HOME/bin:$PATH #VILUME 用于指定持久化目录 VOLUME ["/var/lib/jenkins"] #EXPOSE 映射端口 EXPOSE 8080 EXPOSE 50000 #CMD 运行以下命令 CMD java -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war
#3.上传相关配置文件 [root@ip-10-0-12-212 jenkins]# rz [root@ip-10-0-12-212 jenkins]# ll total 246844 -rw-r--r-- 1 root root 820 Oct 19 15:36 Dockerfile -rw-r--r-- 1 root root 15608 Oct 19 11:30 epel-release-latest-7.noarch.rpm -rw-r--r-- 1 root root 185540433 Oct 18 15:25 jdk-8u131-linux-x64.tar.gz -rw------- 1 root root 3113 Oct 18 17:37 jenkins -rw-r--r-- 1 root root 67200896 Nov 5 2020 jenkins-2.249.3-1.1.noarch.rpm
三、构建Dockerfile
[root@ip-10-0-12-212 jenkins]# docker build --no-cache -t datalake_jenkins:v1 . ... ... Successfully built 1e2736247512 Successfully tagged datalake_jenkins:v1
四、运行Docker容器
#1.运行Jenkins [root@ip-10-0-12-212 jenkins]# docker run -d --name datalake_jenkins -p 10240:8080 -p 10241:50000 datalake_jenkins:v1 517aa3befbca0d9bfc1558c1d4fd4d5b3e0f4bfed6264c22b05254e8b2efb535 #2.查看Docker进程 [root@ip-10-0-12-212 jenkins]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 517aa3befbca datalake_jenkins:v1 "/bin/sh -c 'java -D…" 8 seconds ago Up 6 seconds 0.0.0.0:10240->8080/tcp, :::10240->8080/tcp, 0.0.0.0:10241->50000/tcp, :::10241->50000/tcp datalake_jenkins
五、验证Jenkins
#1.查看持久化存储 [root@ip-10-0-12-212 jenkins]# docker volume ls DRIVER VOLUME NAME local 0cdee244e8f9bb50d0b6bfd34bf2bd0718235bcacca266d74747ae5a9618b2b0 #2.删除没有镜像使用的存储 [root@ip-10-0-12-212 jenkins]# docker volume rm $(docker volume ls -qf dangling=true) #3.查看持久化存储位置 [root@ip-10-0-12-212 jenkins]# docker inspect 517aa3befbca |grep Source "Source": "/data/docker/volumes/0cdee244e8f9bb50d0b6bfd34bf2bd0718235bcacca266d74747ae5a9618b2b0/_data", #4.查看持久化存储数据 [root@ip-10-0-12-212 jenkins]# cd /data/docker/volumes/0cdee244e8f9bb50d0b6bfd34bf2bd0718235bcacca266d74747ae5a9618b2b0/_data [root@ip-10-0-12-212 _data]# ll total 32 -rw-r--r-- 1 root root 1640 Oct 19 17:02 config.xml -rw-r--r-- 1 root root 156 Oct 19 17:01 hudson.model.UpdateCenter.xml -rw------- 1 root root 1712 Oct 19 17:01 identity.key.enc -rw-r--r-- 1 root root 7 Oct 19 17:01 jenkins.install.UpgradeWizard.state -rw-r--r-- 1 root root 171 Oct 19 17:01 jenkins.telemetry.Correlator.xml drwxr-xr-x 2 root root 6 Oct 19 17:01 jobs drwxr-xr-x 3 root root 19 Oct 19 17:01 logs -rw-r--r-- 1 root root 907 Oct 19 17:01 nodeMonitors.xml drwxr-xr-x 2 root root 6 Oct 19 17:01 nodes drwxr-xr-x 2 root root 6 Oct 19 17:01 plugins -rw-r--r-- 1 root root 64 Oct 19 17:01 secret.key -rw-r--r-- 1 root root 0 Oct 19 17:01 secret.key.not-so-secret drwx------ 4 root root 265 Oct 19 17:01 secrets drwxr-xr-x 2 root root 67 Oct 19 17:02 updates drwxr-xr-x 2 root root 24 Oct 19 17:01 userContent drwxr-xr-x 3 root root 56 Oct 19 17:01 users drwxr-xr-x 11 root root 4096 Oct 19 17:01 war #5.WEB页面登录访问 http://52.82.80.128:10240

六、安装Jenkins
#1.解锁Jenkins，找到Jenkins初始密码，输入此密码，点击继续 [root@ip-10-0-12-212 _data]# cat secrets/initialAdminPassword 5900733b0c184e8f80b0650b8137cc9b
