mysql初始化

    mysql_app.sql, 数据库的结构，以及默认账号的初始化
    mysql_auth.sql， 修改密码加密规格，修改密码

nginx

supervisor

[program:lemon]
directory=/app/lemon/website
command=python /app/lemon/website/app.py --port=8989
numprocs=1
process_name=%(program_name)s_%(process_num)02d
autorestart=true
autostart=true
startsecs=5
redirect_stderr=true
stdout_logfile=/app/log/app_%(process_num)02d.log

command 可以使用动态参数，例如：--port=88%(process_num)02d，默认进程使用8800端口，
多进程则修改numproc的值，如numproc=2，则第一个进程使用8800端口，第二个进程使用8801端口。

启动

1. 修改配置文件
2. 编译，docker build -t lemon .
3. docker-compose up -d
