安装Docker Compose

安装Docker Compose

[root@VM-0-12-centos bin]# sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   633  100   633    0     0    656      0 --:--:-- --:--:-- --:--:--   655
100 11.6M  100 11.6M    0     0  42532      0  0:04:48  0:04:48 --:--:-- 39272

为脚本添加执行权限

[root@VM-0-12-centos bin]# chmod a+x /usr/local/bin/docker-compose 

检查是否可用

[root@VM-0-12-centos bin]# docker-compose -v
docker-compose version 1.26.2, build eefe0d31

example

1、先创建3个目录，分别对应ghost app、nginx、data（data用于挂载mysql中的数据）

[root@VM-0-12-centos compose-example]# mkdir nginx
[root@VM-0-12-centos compose-example]# mkdir data
[root@VM-0-12-centos compose-example]# mkdir ghost
[root@VM-0-12-centos compose-example]# ls
data  ghost  nginx

2、在ghost中写好config.js文件

[root@VM-0-12-centos ghost]# cat config.js 
var path = require('path'),config;
config = {
        production: {
                url: 'http://mytestblog.com'
                mail: {},
                database: {
                        client: 'mysql',
                        connection: {
                                host: 'db',
                                user: 'ghost',
                                password: 'ghost',
                                port: '3306',
                                charset: 'utf8'
                        },
                        debug: false
                },
                paths: {
                        contentPath: path.join(process.env.GHOST_CONTENT, '/')
                },
                server: {
                        host: '0.0.0.0',
                        port: '2368'
                }
        }
};
module.exports = config;

3、准备好Dockerfile文件

[root@VM-0-12-centos ghost]# cat Dockerfile 
FROM ghost
COPY ./config.js /var/lib/ghost/config.js
EXPOSE 2368
CMD ["npm", "start", "--production"]

4、配置好nginx的Dockerfile文件

[root@VM-0-12-centos ghost]# cd ../nginx/
[root@VM-0-12-centos nginx]# cat Dockerfile 
FROM nginx
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 80

5、配置nginx.conf

[root@VM-0-12-centos nginx]# cat nginx.conf 
worker processes 4;
events {worker connections 1024}
http {
        server {
                listen 80;
                location / {
                        proxy pass http://ghost-app:2368
                }

        }
}

6、配置好docker-compose.yml配置文件

[root@VM-0-12-centos compose-example]# cat docker-compose.yml
version: '2'

networks :
        ghost

services:
        ghost-app:
                build: ghost
                networks:
                        -ghost
                depends_on:
                        -db
                ports:
                        - "2368:2368"
        nginx:
                build: nginx
                networks:
                        - ghost
                depends_on:
                        - ghost-app
                ports:
                        - "80:80"
        db:
                image: "mysql:5.7.15"
                networks:
                        - ghost
                environment:
                        MYSQL_PORT_PASSWORD: mysqlroot
                        MYSQL_USER: ghost
                        MYSQL_PASSWORD: ghost
                volumes:
                        - /root/mysql-data:/var/libmysql
                ports:
                        - "3306:3306"

7、最终配置好的结果

[root@VM-0-12-centos compose-example]# ls
data  docker-compose.yml  ghost  nginx

docker-compose常用命令
