我想在本地配置的Apache服務器(在Arch Linux上)運行python3腳本,但沒有成功。錯誤500嘗試在本地Apache服務器上運行python腳本

我正在運行mod_fcgid作爲CGI處理程序。

這裏的Python腳本:

#!/usr/bin/python 
print("Content-Type: text/html") 
print() 
print (""" 
<TITLE>CGI script ! Python</TITLE> 
<H1>This is my first CGI script</H1> 
Hello, world! 
""" 
) 

這裏是我的httpd.conf文件:

# 
# This is the main Apache HTTP server configuration file. It contains the 
# configuration directives that give the server its instructions. 
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information. 
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html> 
# for a discussion of each configuration directive. 
# 
# Do NOT simply read the instructions in here without understanding 
# what they do. They're here only as hints or reminders. If you are unsure 
# consult the online docs. You have been warned. 
# 
# Configuration and logfile names: If the filenames you specify for many 
# of the server's control files begin with "/" (or "drive:/" for Win32), the 
# server will use that explicit path. If the filenames do *not* begin 
# with "/", the value of ServerRoot is prepended -- so "logs/access_log" 
# with ServerRoot set to "/usr/local/apache2" will be interpreted by the 
# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log" 
# will be interpreted as '/logs/access_log'. 

# 
# ServerRoot: The top of the directory tree under which the server's 
# configuration, error, and log files are kept. 
# 
# Do not add a slash at the end of the directory path. If you point 
# ServerRoot at a non-local disk, be sure to specify a local disk on the 
# Mutex directive, if file-based mutexes are used. If you wish to share the 
# same ServerRoot for multiple httpd daemons, you will need to change at 
# least PidFile. 
# 
ServerRoot "/etc/httpd" 

# 
# Mutex: Allows you to set the mutex mechanism and mutex file directory 
# for individual mutexes, or change the global defaults 
# 
# Uncomment and change the directory if mutexes are file-based and the default 
# mutex file directory is not on a local disk or is not appropriate for some 
# other reason. 
# 
# Mutex default:/run/httpd 

# 
# Listen: Allows you to bind Apache to specific IP addresses and/or 
# ports, instead of the default. See also the <VirtualHost> 
# directive. 
# 
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses. 
# 
#Listen 12.34.56.78:80 
Listen 127.0.0.1:80

因此,這裏是我的錯誤:

當我嘗試運行了Python文件在服務器上,我收到錯誤代碼爲500的服務器錯誤,並說:

End of script output before headers. 

這裏是我做了什麼來解決它:蟒文件

  1. 搭配chmod 755,使其可執行。
  2. 正確配置目錄,並且正確授予權限。 (我之前得到了拒絕訪問權限)。
  3. 由於我使用的是Python3,因此打印「example_text」時打印(「example_text」)。

它與我裝入的FastCGI模塊有什麼關係?或者python文件?

FastCGI是一個完全不同的協議,然後CGI。您不能將fcgid設置爲CGI腳本的處理程序,以使其作爲FastCGI進程運行,FastCGI進程需要使用不同的機制與stdin/stdout進行通信。

對於Python有一個叫flup一個FastCGI的包裝,它允許主機蟒蛇WSGI應用上的FastCGI的頂部,如果服務器的FastCGI而不是WSGI提供支持,這可能是有用的實現。該程序在一段時間內沒有看到太多活動,但是有一些爲python3提供兼容性的叉,例如, flup6

要開始,你需要安裝flup,並確保運行腳本的用戶可以導入它的好方法是使用venv,例如:

$ python3 -m venv /path/to/venv 
$ chmod a+rX -R /path/to/venv 
$ /path/to/venv/bin/pip install flup6 

這個「Hello World 「對FastCGI的使用python3和flup然後看起來是這樣的:

#!/path/to/venv/bin/python3 

def wsgi_func(environ, start_response): 
    start_response("200 OK", [("Content-Type", "text/html; charset=utf-8")]) 
    response = [b"<html>Hello World</html>"] 
    return response 

if __name__ == '__main__': 
    from flup.server.fcgi import WSGIServer 
    WSGIServer(wsgi_func).run() 

的WSGI功能必須在python3返回bytes迭代而不是SI因此如果將響應創建爲str的列表,則需要在返回之前對其進行編碼,但許多教程仍然使用python2,而從這些教程獲取的示例將無法在python3上運行。

使用FastCGI的另一種方法是使用允許直接託管WSGI應用程序的mod_wsgi
