        include /etc/nginx/default.d/*.conf;

        location / {
                uwsgi_pass unix:///home/sock/[xxx].sock; #此为nginx 使用 sock 的重点
                include /etc/nginx/uwsgi_params;
        }

        error_page 404 /404.html;

        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

启动

service nginx start

supervisor守护进程

安装

pip install supervisor

生成默认配置文件

echo_supervisord_conf > /etc/supervisord.conf

打开 supervisor.conf 在最底部添加

[program:xxx]
command=/usr/bin/uwsgi --ini /home/www/xxx/uwsgi.ini
directory=/home/www/xxx
startsecs=0
stopwaitsecs=0
autostart=true
autorestart=true

启动

supervisord -c /etc/supervisord.conf

重启 xxx项目

supervisorctl -c /etc/supervisord.conf restart xxx

其他命令

supervisorctl -c /etc/supervisord.conf [start|stop|restart] [program-name|all]

开机自启动

nginx

systemcel enable nginx.service

supervisor

vim /lib/systemd/system/supervisord.service

添加以下内容

[Unit]
Description=Process Monitoring and Control Daemon
After=rc-local.service nss-user-lookup.target

[Service]
Type=forking
ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf // 开机启动时执行
ExecStop=/usr/bin/supervisord shutdown // 暂时不知道用处
ExecReload=/usr/bin/supervisord reload // 暂时不知道用处
killMode=process
Restart=on-failure
RestartSec=42s

[Install]
WantedBy=multi-user.target

保存后执行自启动配置

systemctl enable supervisord

验证

systemctl is-enabled supervisord nginx

均为enabled即可
