docker+nginx+jenkins部署前端应用

准备工具

• 下载 -> 安装 -> 部署 jenkins
• 安装docker简介
• linux基本操作命令 (cp、mv、apt-get、yum)

---

一、下载安装docker

1. 下载安装docker https://www.docker.com/get-started
2. 安装portainer,管理docker容器的工具

docker volume create portainer_data
docker run -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

3. 访问本地9000端口,手动创建nginx和jenkins容器

二、配置ssh (SSH是一种网络协议，用于计算机之间的加密登录)

• 安装 openssh-server

apt-get update //更新apt-get资源
apt-get install openssh-server //安装ssh服务

• ssh-keygen

jenkins@jenkins:~/.ssh$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/var/jenkins_home/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /var/jenkins_home/.ssh/id_rsa.
Your public key has been saved in /var/jenkins_home/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:1/Zkmg3ROmqXyV9xv3yLuKB1sPA9pArrAfvO1JfMzO8 jenkins@jenkins
The key's randomart image is:
+---[RSA 2048]----+
|                 |
|             .   |
|            . .  |
|           . o   |
|   .   .S...* o..|
|    o . B.B+ %  +|
|   . + . &o+B o o|
|    + + =.+.o.o.o|
|    o* o  .E...+o|
+----[SHA256]-----+

• 拷贝公钥到目标容器

cd ~/.ssh/

cat id_rsa.pub >> authorized_keys // 创建授权文件

chmod 600 authorized_keys //修改权限
chmod 700 ~/.ssh/ //修改权限

vim /etc/ssh/sshd_config    // 编辑ssh配置文件

RSAAuthentication yes       //加密授权
PubkeyAuthentication yes    // 公钥授权
PermitRootLogin yes         //root用户能通过SSH登录

esc -> shift+: -> (wq (保存退出) q (退出不保存)) 

service ssh restart // 重启ssh服务

docker container ls //查看容器列表

三、配置jenkins

• 查看jenkins映射的端口号

  
  image.png

• 访问 localhost:9999

• jenkins配置nodejs

• jenkins配置git仓库

• 使用 jenkins shell

rm -rf node_modules && npm i
npm run build
ssh -t root@172.17.0.3 "mkdir /usr/share/nginx/html/demo"  // -t 不显示终端，只显示连接成功信息
scp -r ./build/* root@172.17.0.3:/usr/share/nginx/html/demo  

四、配置nginx

找到nginx容器的id

image.png

注：nginx有默认的配置文件在 /etc/nginx/conf.d/default.conf ,这里要删掉，用我们自己的/etc/nginx/nginx.conf

rm  /etc/nginx/conf.d/default.conf 

vim /etc/nginx/nginx.conf

// 在server结构中新增
server {
    listen 80; //监听的端口号
    
    // 匹配访问路径
    location / {
       root   /usr/share/nginx/html/demo; // 项目的路径
       try_files $uri /index.html /index.htm /index; // 要访问的文件名
   }
}

****** 编辑完成后执行
nginx -s reload //重新载入配置
