Docker Nginx 开启多个服务
使用 docker 安装 Nginx 反向代理服务器，实现二级域名功能
部署两个二级域名的服务
这里部署两个项目，一个是使用Flask开发的bookstore，另一个是使用Django开发的数据可视化项目covid-19。
bookstore
version: '2.0'
services:
mysql_bs:
image: mysql
restart: always
networks:
- bookstore_net
command: '--default-authentication-plugin=mysql_native_password'
volumes:
- ./script/data/mysql/init:/docker-entrypoint-initdb.d/
environment:
MYSQL_ROOT_PASSWORD: 'root'
mongo:
restart: always
build:
context: .
dockerfile: mongo-dockerfile
privileged: true
networks:
- bookstore_net
volumes:
- /home/caisi/bookstore/script/data/mongo/init:/mongo/back
environment:
MONGO_INITDB_DATABASE: bookstore
MONGO_INITDB_ROOT_USERNAME: root
MONGO_INITDB_ROOT_PASSWORD: root
# nginx:
# image: nginx
# restart: always
# volumes:
# - ./conf/nginx.conf:/etc/nginx/conf.d/default.conf
# - ~/nginx:/etc/nginx/conf.d/
# ports:
# - 80:80
# depends_on:
# - bookstore
# links:
# - bookstore
bookstore:
restart: always
build:
context: .
dockerfile: Dockerfile
#volumes:
#- .:/code
# - /etc/localtime:/etc/localtime # 时区
expose:
- 8000
links:
- mysql_bs
- mongo
networks:
- bookstore_net
networks:
bookstore_net:
driver: bridge这里的nginx服务注销了是因为要开启两个服务加入到nginx中，所以需要把nginx单独放出来
dv（数据可视化）
version: '2.0'
services:
mysql:
image: mysql
#build:
# context: .
# dockerfile: docker-mysql
restart: always
networks:
- dv-net
command: '--default-authentication-plugin=mysql_native_password'
volumes:
- ./data/:/docker-entrypoint-initdb.d/
- ./config/mysql.cnf:/etc/mysql/conf.d/my.cnf
environment:
MYSQL_ROOT_PASSWORD: 'root'
# nginx:
# image: nginx
# restart: always
# volumes:
# - ./config/nginx.conf:/etc/nginx/conf.d/default.conf
# ports:
# - 81:80
# links:
# - covid_dv
covid_dv:
restart: always
build:
context: .
dockerfile: Dockerfile
# volumes:
# - :/
networks:
- dv-net
# ipv4_address: 172.20.0.2
ports:
- 8001:8001
expose:
- 8001
links:
- mysql
networks:
dv-net:
driver: bridge这里的nginx也和上面的一样，在单独运行的时候才开启
这个dv项目的github地址：https://github.com/caisi35/DataVisualization/tree/master/covid_19_dv
docker 网络
- 创建自定义网卡的docker命令：
docker network create xxxxxxx_name caisi@iZbp142i6z3h2th6j7ehvyZ:~/covid_19_dv$ docker network ls
NETWORK ID NAME DRIVER SCOPE
65215fa7b138 bookstore_bookstore_net bridge local
b0ac60625ee0 bookstore_default bridge local
1b6e904504fe bridge bridge local
944d9d8d2667 covid19dv_dv-net bridge local
f1e7dcca0fc6 host host local
9f9104f35bc3 none null local这里为两个服务都设置了自定义的network，bookstore项目的bookstore_net 和 dv 的 dv-net，这里没有设置网络的名称，所以docker自动会加上docker-compose.yml文件的文件夹名称和networks作为NAME。所以就是上面的bookstore_bookstore_net, covid19dv_dv-net，bookstore_default是之前单独部署bookstore的时候docker创建的默认的网络。
部署Nginx
重点来了
version: '2.0'
services:
nginx:
image: nginx
restart: always
container_name: nginx
volumes:
#- ./conf/nginx.conf:/etc/nginx/conf.d/default.conf
- ~/nginx:/etc/nginx/conf.d/
ports:
- 80:80
networks:
- bookstore_bookstore_net
- covid19dv_dv-net
networks:
bookstore_bookstore_net:
external: true
covid19dv_dv-net:
external: true这里把上面两个项目的网卡加入到nginx中，否则nginx会找不到服务的HOST。
并把~/nginx目录映射为nginx的配置文件放置的目录，把bookstore, covid_19的nginx配置文件放入物理主机的~/nginx，重启nginx容器。
caisi@iZbp142i6z3h2th6j7ehvyZ:~/nginx$ ls
nginx-bs.conf nginx-dv.conf
caisi@iZbp142i6z3h2th6j7ehvyZ:~/nginx$ cat nginx-bs.conf
server {
listen 80;
server_name bs.caisi.xyz;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
location / {
proxy_pass http://bookstore:8000;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
caisi@iZbp142i6z3h2th6j7ehvyZ:~/nginx$ cat nginx-dv.conf
server {
listen 80;
server_name dv.caisi.xyz;
# server_name localhost;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
location / {
proxy_pass http://covid_dv:8001;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}这里的nginx配置文件主要就是server_name和proxy_pass两个地方，server_name是二级域名解析的地址，proxy_pass则是需要代理的项目地址和端口，这里的bookstore, covid_dv分别是对应项目中docker-compose.yml文件中的服务。

踩坑记录
Nginx 没有找到相应的IP
看情况，应该是covid_19_dv这个应用引起的，因为没有启动，所以docker的network没有相应的IP，最终导致Nginx启动的时候配置文件那里报错了。
解决：1. 删除covid_19_dv的Nginx配置文件。 2. 启动covid_19_dv，让Nginx找到IP。
结论：需要先启动各个项目后，才启动nginx容器，这样nginx的配置文件才能找到相应的HOST。
各个项目的networks，需要手动的创建。
nginx映射的~/nginx目录操作需要sudo权限。
Django的settings.py中需要添加允许的HOSTS。
Django的静态文件需要单独配置，可以在uwsgi.ini添加static-map = /static=/covid_19_dv/static。
常用docker、docker-compose命令
docker ps
# 查看docker启动了的容器， 加`-a`查看所有的容器，包括没有启动的

docker network rm network_name总结
- 这里主要就是为了能让Nginx容器找到其它的项目部署的容器的
HOST，所以涉及到了docker的网络。 - Django的项目部署静态文件需要特别注意一下，与Flask不同，Django默认有很多的
APP，因此static目录也可以有多个，所以需要特地的配置一下。
