珠峰架构师成长计划

1.持续集成和布署 #

技术栈前台Vue,后台Node.js
服务器前台nginx,后台Node.js

webhookscicd2

2.编写后端服务 #

2.1 package.json #

/usr/projects/vue-back/package.json

{
  "name": "vue-back",
  "version": "0.0.0",
  "private": true,
  "scripts": {
+    "start": "node ./server.js "
  }
}

2.2 server.js #

/usr/projects/vue-back/server.js

let http = require('http');
let users = [{id:1,name:'zhufeng1'},{id:2,name:'zhufeng2'},{id:3,name:'zhufeng3'}];
let server = http.createServer(function(req,res){
  console.log(req.method,req.url);
  if(req.url == '/api/users'){
    res.setHeader('Access-Control-Allow-Origin','*');
    res.end(JSON.stringify(users));
  }else{
    res.end('Now Found!');
  }
});

5. 配置服务器 #

5.1 更新系统 #

#升级所有包同时也升级软件和系统内核
yum update 
#只升级所有包，不升级软件和系统内核
yum upgrade

5.2 docker是什么? #

Docker 属于 Linux 容器的一种封装，提供简单易用的容器使用接口。
Docker 将应用程序与该程序的依赖，打包在一个文件里面。运行这个文件，就会生成一个虚拟容器。程序在这个虚拟容器里运行，就好像在真实的物理机上运行一样

dockercontainer

5.3 安装docker #

yum install -y yum-utils   device-mapper-persistent-data   lvm2
yum-config-manager \
    --add-repo \
    https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install -y docker-ce docker-ce-cli containerd.io

5.4 阿里云加速 #

mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://fwvjnv59.mirror.aliyuncs.com"]
}
EOF
# 重载所有修改过的配置文件
systemctl daemon-reload
systemctl restart docker

5.5 生成公钥并添加github #

https://github.com/settings/keys

ssh-keygen -t rsa -b 4096 -C "zhufengnodejs@126.com"
cat /root/.ssh/id_rsa.pub

5.6 安装git #

yum install git -y
git clone git@github.com:zhufengnodejs/vue-front.git
git clone git@github.com:zhufengnodejs/vue-back.git
git clone git@github.com:zhufengnodejs/vue-webhook.git

~.gitconfig

[alias]
    a = add -A
    c = commit -m"msg"
    p = push origin master

5.7 安装node和npm #

nvm

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash
source /root/.bashrc
nvm install stable
npm i nrm -g
nrm use taobao

8. 集成部署 #

Compose 通过一个配置文件来管理多个Docker容器
在配置文件中，所有的容器通过services来定义，然后使用docker-compose脚本来启动、停止和重启应用和应用中的服务以及所有依赖服务的容器
最后，运行docker-compose up，Compose 将启动并运行整个应用程序配置文件组成

8.1 docker-compose.yml #

/usr/projects/docker-compose.yml

version: '2'
services:
 api:
  build:
    context: ./vue-back
    dockerfile: Dockerfile
  ports:
    - "3000:3000"
 web:
  build:
    context: ./vue-front
    dockerfile: Dockerfile
  ports:
    - "80:80"

8.2 安装docker-compose #

curl -L https://github.com/docker/compose/releases/download/1.23.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

8.3 启动服务 #

docker-compose up
docker-compuse up -d

8.4 cicd.sh #

/usr/projects/vue-webhook/cicd.sh

#!/bin/bash
WORK_PATH='/usr/projects/vue-back'
cd $WORK_PATH
echo "清理后台代码"
git reset --hard origin/master
git clean -f
echo "拉取后台最新代码"
git pull origin master


WORK_PATH='/usr/projects/vue-front'
cd $WORK_PATH
echo "清理前台代码"
git reset --hard origin/master
git clean -f
echo "拉取前台最新代码"
git pull origin master
echo "打包前台最新代码"
npm run build

cd /usr/projects
echo "删除老资源"
docker-compose down
echo "重启所有服务"
docker-compose up -d
