基于Jenkins自动打包并部署docker环境

1、安装docker-ce

在192.168.2.123 机器上，构建 tomcat基础镜像。在构建基础镜像之前需要先安装 Docker 与 JDK。

[root@docker ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

[root@docker ~]# yum -y install yum-utils device-mapper-persistent-data lvm2
[root@docker ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

[root@docker ~]# ls /etc/yum.repos.d/
backup  CentOS-Base.repo  CentOS-Media.repo  docker-ce.repo

[root@docker ~]# yum -y install docker-ce
[root@docker ~]# systemctl start docker
[root@docker ~]# systemctl enable docker
[root@docker ~]# docker version

3、构建tomcat 基础镜像 

[root@tomcat ~]# mkdir docker-tomcat

[root@tomcat ~]# mv apache-tomcat-8.5.40.tar.gz docker-tomcat/

[root@tomcat ~]# mv jdk-8u191-linux-x64.tar.gz docker-tomcat/

[root@tomcat ~]# cd docker-tomcat/

[root@tomcat docker-tomcat]# ls
apache-tomcat-8.5.40.tar.gz  jdk-8u191-linux-x64.tar.gz

[root@tomcat docker-tomcat]# vim Dockerfile

4、构建一个Maven项目

在以上配置完成后，回到 Jenkins 首页，选择“新建任务”，然后输入一个任务名称 “probe-docker”，并选择“Maven project”配置项，点击当前页面下方的“确定”按钮。

 

 在点击“确定”按钮，选择“源码管理”并选中“Git”,设置“Repository URL”地址。

 选择“Build”-> clean package -Dmaven.test.skip=true

 在上一步后面选择“构建后操作”中的“Send build artfacts over SSH”选项并进行。

scp 192.168.2.122:/root/.jenkins/workspace/proble/psi-probe-web/target/probe.war /data/
docker run -itd --name tomcat-test -p 8090:8080 -v /data:/usr/local/apache-tomcat-8.5.40/webapps tomcat:v1

 

         以上全部配置完成后，点击保存即可。然后点击刚才创建的工程任务“probe-docker“->” Build new”直至任务构建完成。开始构建过程中可以点击进度条查看

 

 可以看到此工程任务已构建成功，并且在构建后，创建用于docker项目的 Docker Web 环境命令也执行成功。

[root@tomcat ~]# docker ps

CONTAINER ID   IMAGE       COMMAND                   CREATED         STATUS         PORTS                                       NAMES

基于Jenkins自动化部署PHP环境

准备git仓库

[root@git ~]# su - git

上一次登录：四 8月 24 11:32:12 CST 2023从 192.168.2.122pts/3 上

[git@git ~]$ mkdir php.git

[git@git ~]$ cd php.git

[git@git php.git]$ git --bare init

已初始化空的 Git 仓库于 /home/git/php.git/

[git@git php.git]$ exit

登出

上传代码到仓库

[root@git ~]# git clone [email protected]:/home/git/php.git

正克隆到 'php'...
[email protected]'s password:             #密码是123456
warning: 您似乎克隆了一个空仓库。

[root@git ~]# cd php/

[root@git php]#  cat << EOF > index.php
>  phpinfo();
> ?>
> EOF

[root@git php]# git add .

[root@git php]#  git commit -m "all"

To 192.168.2.121:/home/git/php.git
 * [new branch]      master -> master

部署web主机环境

[root@tomcat ~]# yum install -y httpd mariadb-server mariadb mariadb-devel php php-mbstring php-mysql php-bcmath php-gd php-xmlrpc php-ldap php-xml libevent libevent-devel net-snmp net-snmp-devel libxml2 libxml2-devel ntpdate

[root@tomcat ~]# systemctl start httpd
[root@tomcat ~]# systemctl start mariadb

 Jenkins主机将密钥发布到web主机

[root@jenkins ~]# su -s /bin/bash jenkins

bash-4.2$ ssh-keygen

bash-4.2$ ssh-copy-id [email protected]

/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/var/lib/jenkins/.ssh/id_rsa.pub"

[email protected]'s password:

and check to make sure that only the key(s) you wanted were added.

基于rsync部署

创建一个Freestyle project

 

 rsync -avz --delete * [email protected]:/var/www/html/

 

 

 

[root@tomcat ~]# ls /var/www/html/

index.php

[root@tomcat ~]# cat /var/www/html/index.php 

 基于ansible部署
