项目是采用 gunicorn dango nginx 方式部署的。
gunicorn.py采用如下方式配置，
workers = 1 bind = '0.0.0.0:8000' backlog = 2048 timeout = 6000 keepalive = 6000 errorlog = '../error.log' loglevel = 'info' logFile = '../sys.log' accesslog = '../access.log' worker_class = 'gthread' worker_connections = 1000
/etc/systemd/system/cmdb.service
[root@localhost system]# cat cmdb.service [Unit] Description=cmdb After=network.target [Service] User=root Group=root Environment="APP_ENV=prd" WorkingDirectory=/data/cmdb/ ExecStart=/usr/local/bin/gunicorn cmdb.wsgi:application -c /data/cmdb/gunicorn.py [Install] WantedBy=multi-user.target
之后启动systemctl start cmdb。程序没问题，有问题的地方是有一个耗时很长的同步任务，会导致页面，程序接口都卡着。就很好奇，gunicorn不就是异步的么，难道不能处理类似的并发请求？
经过一番折腾，python - 如何让 Flask/Gunicorn 处理同一路由的并发请求？ gunicorn使用
解决办法：
加上threads就解决了
把gunicorn.py 改下，重启systemctl restart cmdb，完美解决。
