Docker安装Jenkins-2.249.3-1.1的详细过程

一、安装docker

#1.编写docker安装脚本
[root@ip-10-0-12-212 ~]# vim ins_docker.sh 
#!/usr/bin/bash
# author:jh
# time:2021-10-09  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 ...";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、拉取jenkins镜像文件

[root@ip-10-0-12-212 ~]# docker pull jenkins/jenkins

三、创建挂载目录并授权

[root@ip-10-0-12-212 ~]# mkdir -p /data/jenkins_mount
[root@ip-10-0-12-212 ~]# chmod  777 /data/jenkins_mount

四、创建并启动jenkins容器

[root@ip-10-0-12-212 ~]# docker run -d -p 10240:8080 -p 10241:50000 -v /data/jenkins_mount:/var/jenkins_home -v /etc/localtime:/etc/localtime --name datalake_jenkins jenkins/jenkins
e0a9964d61fd5eb9f1c0eae0f2f18bdbfcd03ff0d5c2cc0d0beae31c134afa75

五、查看jenkins是否启动成功

[root@ip-10-0-12-212 ~]# docker ps
container id   image             command                  created          status          ports                                                                                        names
e0a9964d61fd   jenkins/jenkins   "/sbin/tini -- /usr/…"   13 seconds ago   up 12 seconds   0.0.0.0:10240->8080/tcp, :::10240->8080/tcp, 0.0.0.0:10241->50000/tcp, :::10241->50000/tcp   datalake_jenkin

六、查看docker容器日志

[root@ip-10-0-12-212 ~]# docker logs datalake_jenkins
running from: /usr/share/jenkins/jenkins.war
webroot: envvars.masterenvvars.get("jenkins_home")

七、访问jenkins

访问jenkins页面，http://52.82.80.128:10240

八、安装jenkins

[root@ip-10-0-12-212 ~]# cd /data/jenkins_mount/
[root@ip-10-0-12-212 jenkins_mount]# cat secrets/initialadminpassword 
67925445271c4fe593ba83eede0f9c75

#2.选择安装推荐的插件

#3.填入相应的管理用户信息，点击保存并完成。

#4.配置此处jenkins的url。

#5.此处jenkins已经安装就绪，点击开始使用jenkins。

#6.此处已经进入jenkins页面，右下角显示安装的版本号，至此jenkins安装完毕。
