使用Nginx 和Supervisor在Linux服务器上部署Tornado

Nginx 安装: sudo apt-get install nginx

Nginx 安装后用浏览器进入127.0.0.1就可以看到nginx的欢迎页了

nginx 常用命令

1. sudo service nginx start 启动nginx
2. sudo service nginx stop 停止nginx
3. sudo service nginx restart 重启nginx
4. sudo service nginx reload 重新加载配置文件

Supervisor 安装: sudo apt-get install supervisor

部署步骤：

• Tornado项目路径 : /home/你的用户名/Tornado项目文件夹名称/main.py

• 在/etc/nginx/下　创建nginx.conf配置文件
  这里我们使用8000-8003四个端口，进行端口转发　配置文件编写要注意main.py所在位置要写对,即下面配置文件中的中文

user root;
worker_processes auto;
pid /run/nginx.pid;

events {
    worker_connections 768;
    multi_accept on;
    use epoll;
}
http {
    # Enumerate all the Tornado servers here
    upstream frontends {
        server 127.0.0.1:8000;
        server 127.0.0.1:8001;
        server 127.0.0.1:8002;
        server 127.0.0.1:8003;
    }

    include /etc/nginx/mime.types;
    default_type application/octet-stream;
    access_log /var/log/nginx/access.log;

    keepalive_timeout 65;
    proxy_read_timeout 200;
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    gzip on;
    gzip_min_length 1000;
    gzip_proxied any;
    gzip_types text/plain text/html text/css text/xml
               application/x-javascript application/xml
               application/atom+xml text/javascript;
    proxy_next_upstream error;

    server {
        listen 80;

        # Allow file uploads
        client_max_body_size 50M;

        location ^~ /static/ {
            root /home/用户名/项目文件夹名/;
            if ($query_string) {
                expires max;
            }
        }
        location = /favicon.ico {
            rewrite (.*) /static/favicon.ico;
        }
        location = /robots.txt {
            rewrite (.*) /static/robots.txt;
        }

        location / {
            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;
        }
    }
}

• 编写supervisor配置文件

• 进入supervisor配置文件夹 cd /etc/supervisor/conf.d/

• 创建tornados.conf

[group:tornadoes]
programs=tornado-8000,tornado-8001,tornado-8002,tornado-8003

[program:tornado-8000]
command=python /home/用户名/项目文件夹名/main.py --port=8000
directory=/home/用户名/项目文件夹名
user=root
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/tornado.log
loglevel=info

[program:tornado-8001]
command=python /home/用户名/项目文件夹名/main.py --port=8001
directory=/home/用户名/项目文件夹名
user=root
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/tornado.log
loglevel=info

[program:tornado-8002]
command=python /home/用户名/项目文件夹名/main.py --port=8002
directory=/home/用户名/项目文件夹名
user=root
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/tornado.log
loglevel=info

[program:tornado-8003]
command=python /home/用户名/项目文件夹名/main.py --port=8003
directory=/home/用户名/项目文件夹名
user=root
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/tornado.log
loglevel=info

• 其中/var/log/tornado.log为日志文件目录
  然后先重载nginx的配置文件 sudo service nginx reload
  重启 nginx : sudo service nginx restart
  supervisor开启所有进程: sudo supervisorctrl restart all

再次打开127.0.0.1后可以看到项目已经成功部署。
