nginx

安装：sudo apt-get install nginx
配置文件：sudo vim /etc/nginx/sites-available/default

# nginx -c /etc/nginx/nginx.conf 
关闭 nginx
# nginx -s stop
重读配置文件
# nginx -s reload
# pkill -HUP nginx
重新打开日志文件
# nginx -s reopen

还可以下载 nginx RPM 包中的 /etc/init.d/nginx 文件，修改路径后即可使用：
# service nginx {start|stop|status|restart|reload|configtest|}

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;
    
    # 如果要支持HTTPS，修改这里
    # 可以使用 https://letsencrypt.org 的免费SSL证书
    #listen 443 ssl;
    #ssl_certificate     www.example.com.crt;
    #ssl_certificate_key www.example.com.key;
    #ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    #ssl_ciphers         HIGH:!aNULL:!MD5;
    
    # 重定向所有HTTP到HTTPS
    # rewrite ^(.*)$ https://$host$1 permanent;

    # 网站根目录，根据需要修改
    root /usr/share/nginx/html;
    # 增加index.php
    index index.php index.html index.htm;

    # 假设域名是 ssl.mcxiaoke.com
    server_name ssl.mcxiaoke.com; #绑定域名

    location / {
        try_files $uri $uri/ =404;
    }

    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    #支持php-fpm的配置
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

Supervisor

directory = /home/mcxiaoke/myapp
user = mcxiaoke

读取并执行任务

sudo pkill gunicorn
sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start myapp
