Question

使用modwsgi

在apache上运行python / django

我一直在寻找通过我的apache error_log而且我注意到了一些奇怪的事情

我只有2个带wsgi守护进程的虚拟主机但是当我启动httpd服务时，我得到了很多python初始化（我已经算了17次）

这是另一个就像这样

 WSGIDaemonProcess myproject python-path=/home/xyz/public_html/myproject:/usr/local/lib/python3.4/site-packages/
 WSGIProcessGroup myproject
 WSGIScriptAlias / /home/xyz/public_html/myproject/myproject/wsgi.py
  <Directory /home/xyz/public_html/myproject/myproject>
     <Files wsgi.py>
      Order deny,allow
      Require all granted
      WSGIProcessGroup myproject
    </Files>
   </Directory>
Alias /static/ /home/xyz/public_html/myproject/static/
<Directory /home/xyz/public_html/myproject/static>
Require all granted
</Directory>

这是我启动httpd时得到的内容

这是正常还是有问题？

Answer 1

这似乎要启动很多流程。您可以尝试向WSGIDaemonProcess添加一些额外的参数，以显式设置它应该生成的进程数和线程数。在你的情况下，尝试这样的事情（注意最右边的指令）：

WSGIDaemonProcess myproject python-path=/home/xyz/public_html/myproject:/usr/local/lib/python3.4/site-packages/ processes=2 threads=5

此处有关这些指令的更多信息：http://modwsgi.readthedocs.io/en/develop/configuration-directives/WSGIDaemonProcess.html

Answer 2

关闭Apache子进程中Python解释器的初始化。读：

http://blog.dscpl.com.au/2009/11/save-on-memory-with-modwsgi-30.html

这样Python只会在mod_wsgi守护进程中初始化。

httpd start上的python初始化太多了
