学习tornado有一周多了，自己按着demo中的例子手动搬代码，收获还是有的，加深了理解。demo: http://demo.pythoner.com/itt2zh/ch8.html

大概明白了它怎么工作后，开始部署一个线上环境跑跑。

nginx: 分配客户端请求给upstream组中列出的Tornado实例。其中静态目录的文件由nginx直接提供。

supervisord: tornado进程管理。

tornado: 功能实现。

关于nginx

在/etc/nginx/site-enable/default中新增：

upstream frontends{
    server 127.0.0.1:8880;
}

server {
    listen 8000;
 
    location / {
        proxy_read_timeout 1800;
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_pass http://frontends;
    }
}

关于supervisord

确认是否已install supervisord，安装后可查看状态“sudo supervisorctl status”;

$ vi /etc/supervisor/supervisord.conf

; supervisor config file

[unix_http_server]
file=/var/run/supervisor.sock   ; (the path to the socket file)
chmod=0700                       ; sockef file mode (default 0700)

[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor            ; (‘AUTO‘ child log dir, default $TEMP)

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL  for a unix socket

; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

[include]
files = /etc/supervisor/conf.d/*.conf

[include]
files = /etc/supervisor/conf.d/*.conf

即可在/etc/supervisor/conf.d/ 目录下$vi tornado_demo.conf

[program:tornado_demo]
command=python /var/www/tornado_example/munger/main.py --port=8880
autostart=true
autorestart=true
redirect_stderr=true
stdout_logfile = /var/log/munger/munger.log
stderr_logfile = /var/log/munger/error.log
