目录
实验目的
实验步骤
1、拉取在线centos 7的yum源和epel扩展源
2、安装compose工具
3、获取所需的镜像（ghost、mysql、nginx）
4、创建ghost目录，在ghost目录中创建三个子目录（data、ghost、nginx）
5、切换到ghost目录的ghost子目录，编写Dockerfile文件
6、创建config.js文件，用于ghost的配置
7、切换到ghost目录的nginx的子目录中，编写Dockerfile文件
8、配置nginx的配置文件nginx.conf
9、返回到ghost目录，编写docker-compose.yml文件
10、执行脚本文件，完成服务的安装与部署，并查看创建的服务
11、测试，访问Ghost博客
实验目的
利用Compose编排服务搭建博客系统，用户可以通过nginx来访问博客系统。
实验步骤
1、拉取在线centos 7的yum源和epel扩展源
## 拉取在线centos7的yum源
[root@docker ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

[root@docker ~]# wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo

2、安装compose工具
[root@docker ~]# yum -y install docker-compose
[root@docker ~]# docker-compose --version
docker-compose version 1.18.0, build 8dd22a93、获取所需的镜像（ghost、mysql、nginx）
[root@docker ~]# docker pull ghost:1-alpine
[root@docker ~]# docker pull mysql:5.7.15
[root@docker ~]# docker pull nginx:latest
[root@docker ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx latest a830707172e8 2 weeks ago 192MB
ghost 1-alpine efcd4044e3a0 5 years ago 268MB
mysql 5.7.15 18f13d72f7f0 8 years ago 383MB4、创建ghost目录，在ghost目录中创建三个子目录（data、ghost、nginx）
[root@docker ~]# mkdir /ghost
[root@docker ~]# cd /ghost/
[root@docker ghost]# mkdir {data,ghost,nginx}
[root@docker ghost]# ls
data ghost nginx5、切换到ghost目录的ghost子目录，编写Dockerfile文件
[root@docker ghost]# cd ghost/
[root@docker ghost]# vi Dockerfile
[root@docker ghost]# cat Dockerfile
FROM ghost:1-alpine
COPY ./config.js /var/lib/ghost/config.js
EXPOSE 2368
#CMD ["npm","start","--production"]6、创建config.js文件，用于ghost的配置
[root@docker ghost]# vi config.js
[root@docker ghost]# cat config.js
var path = require('path'),config;config = {production: {url: 'http://my-ghost-blog.com',mail: {},database: {client: 'mysql',connection: {host: 'db',user: 'ghost',password: '123456',database: ''ghost,port: '3306',charset: ''utf-8,},debug: false},paths: {contentPath: path.jion(process.env.GHOST_CONTENT, '/')},server: {host: '0.0.0.0',port: '2368'},}
}
// Export config
module.exports = config;7、切换到ghost目录的nginx的子目录中，编写Dockerfile文件
[root@docker ghost]# cd ../nginx
[root@docker nginx]# vi Dockerfile
[root@docker nginx]# cat Dockerfile
FROM nginx
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 808、配置nginx的配置文件nginx.conf
[root@docker nginx]# vi nginx.conf
[root@docker nginx]# cat nginx.conf
work_processes 4;
events {worker_connections 1024;}
http {server{listen 80;location / {proxy_pass http://ghost-app:2368;}}
}9、返回到ghost目录，编写docker-compose.yml文件
[root@docker nginx]# cd ..
[root@docker ghost]# vi docker-compose.yml
[root@docker ghost]# cat docker-compose.yml
version: "3"
networks:blog:
services:ghost-app:build: ghostrestart: alwaysnetworks:- blogdepends_on:- dbports:- "2368:2368"nginx:build: nginxrestart: alwaysnetworks:- blogdepends_on:- ghost-appports:- "80:80"db:image: "mysql:5.7.15"networks:- blogenvironment:MYSQL_ROOT_PASSWORD: mysqlrootMYSQL_USER: ghostMYSQL_PASSWORD: 123456volumes:- $PWD/data:/var/lib/mysqlports:- "3306:3306"## 检测docker-compose.yml编排文件
[root@docker ghost]# docker-compose config
10、执行脚本文件，完成服务的安装与部署，并查看创建的服务
[root@tangjing ghost]# docker-compose up -d
