docker-compose.yml文件内容：

我们在docker-compose里面配置了mysql的账号，以及wordpress的连接池账号

创建应用目录
mkdir -p /app/nginx
mkdir -p /app/mysql
mkdir -p /app/wordpress

进入nginx目录并新建配置文件

这里创建nginx主配置文件
cd /app/nginx
touch nginx.conf

root@iZuf6hvlnilb22btlcji2yZ:/app/nginx# cat nginx.conf usernginx;worker_processes1;error_log/var/log/nginx/error.log warn;pid/var/run/nginx.pid;events {worker_connections1024;}http {include /etc/nginx/mime.types;default_typeapplication/octet-stream;log_formatmain'$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';access_log/var/log/nginx/access.logmain;sendfileon;#tcp_nopush on;keepalive_timeout65;#gzipon;include /etc/nginx/conf.d/*.conf;}

然后创建nginx子配置文件
mkdir conf.d
touch conf.d/default.conf

root@iZuf6hvlnilb22btlcji2yZ:/app/nginx/conf.d# cat default.conf server {listen 80;server_name localhost hechaojie.com;location / {proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_set_header Host $http_host;proxy_pass http://wordpress;}}

配置完成后执行：
docker-compose up -d

浏览首页就可以安装wordpress了
