nginx 報錯
upstream prematurely closed connection while reading response header from upstream說明是上游服務器出現了問題
所以是uwsgi出現問題
uwsgi 報錯
uwsgi -- unavailable modifier requested: 01. 解決辦法一
此時uwsgi是用yum安裝的
yum search vim uwsgi-plugin-python找到對應版本的uwsgi-plugin-python,yum install一下
然後在ini文件中添加plugins = python,或者命令行添加–plugin python
比如我的python是python3.6.4
[root@localhost conf.d]# yum search vim uwsgi-plugin-python

Complete!安裝完成後，需要在此項目的uwsgi的ini文件中設置參數plugins = python36
=================成功解決BUG的第三天=================
今天又部署了一個項目，但是項目是python2.7開發的
然後按照之前的解決方式，安裝了uwsgi-plugin-python2 然後ini文件中設置了plugins = python2，依然存在問題
然後又嘗試安裝uwsgi-plugin-python2-gevent，還是沒有用
只能祭出終極絕招了！
2. 解決辦法二
首先卸載了yum安裝的uwsgi
yum remove uwsgi然後分別進入兩個項目的虛擬環境，在虛擬環境中單獨使用pip安裝uwsgi
然後再supervisord的ini文件中，指定uwsgi的啓動路徑（即虛擬環境的bin目錄），然後問題解決了！！！
