一、前期准备
需要准备php，mysql，nginx镜像。下面是我安装的镜像。
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/phpdockerio/php72-fpm latest 01cc79d26d94 9 days ago 164 MB
docker.io/mysql latest e3fcc9e1cc04 13 days ago 544 MB
docker.io/nginx latest 8cf1bfb43ff5 13 days ago 132 MB
目录结构如下：
[root@localhost ~]# tree /www
/www
├── conf
│ └── php.conf
├── logs
└── web
└── index.php
3 directories, 2 files
web 是网站的目录
conf Nginx的配置目录
其中，/www/conf/php.conf下的文件内容如下：
server {
listen 80;
server_name localhost;
location / {
root /usr/share/nginx/html;
index index.html index.htm index.php;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location ~ \.php$ {
fastcgi_pass php:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /web/$fastcgi_script_name;
include fastcgi_params;
}
}
二、编写docker-compose.yml文件
在工作的目录下创建docker-compose.yml文件。
version: "2.3"
services:
nginx:
image: nginx
privileged: true
ports:
- "80:80"
volumes:
- /www/web:/usr/share/nginx/html
- /www/conf:/etc/nginx/conf.d
- /www/logs:/var/log/nginx
networks:
- web-net
php:
image: phpdockerio/php72-fpm
privileged: true
volumes:
- /www/web:/web
networks:
- web-net
mysql:
image: mysql
ports:
- "3306:3306"
environment:
- MYSQL_ROOT_PASSWORD=root
networks:
- web-net
networks:
web-net:
严格注意yaml格式。
privileged 用来设置容器，需要操作挂载的权限
实例：
[root@localhost ~]# docker-compose up -d
Creating network "root_web-net" with the default driver
Creating root_nginx_1 ... done
Creating root_php_1 ... done
Creating root_mysql_1 ... done
构建成功
在/www/web下，新建index.php，能正常访问。
