我试图在我的nginx Web服务器上运行一个hello world python脚本.当我尝试加载URI时,我收到“502 Bad Gateway”错误：http://sub.dom.com/py-bin/hello.py

这是我的nginx错误日志中的错误.

袜子的位置：

ls /var/run | grep sock
fcgiwrap.socket
php5-fpm.sock

hello.py的内容

#!/usr/bin/python

print "Content-type: text/html\n\n"
print "Hello world"

请注意PHP工作正常.

解决方法:

尝试将响应代码(“HTTP / 1.0 200 OK”)添加到hello.py输出的顶部,如下所示：

#!/usr/bin/python

print "HTTP/1.0 200 OK"
print "Content-type: text/html\n\n"
print ""
print "Hello world"
