Python 2:

sh 复制代码

$ python -m SimpleHTTPServer 9000

If you are running Python 3, you will get error as No module named SimpleHTTPServer. It's because in python 3, SimpleHTTPServer has been merged into http.server module. You can use below command to run python http server in Python 3.

sh 复制代码

$ python3 -m http.server
Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...

To explicitly set the port number that your HTTP server should be listening on, append it as a parameter:

sh 复制代码

$ python3 -m http.server 8080
Serving HTTP on 0.0.0.0 port 8080 (http://0.0.0.0:8080/) ...

Port 80 is a standard port reserved for HTTP traffic. However, if you'd like to start a local web server on that special port, then you'll have to run the corresponding command as the superuser with administrative privileges. Otherwise, you'll get another error:

sh 复制代码

$ python3 -m http.server 80
Traceback (most recent call last):
  ...
PermissionError: [Errno 13] Permission denied

You can bind a specific network interface or IP address by using the -b option:

sh 复制代码

$ python3 -m http.server -b 127.0.0.42 8080
Serving HTTP on 127.0.0.42 port 8080 (http://127.0.0.42:8080/) ...

To enforce a different address, you can use the -b option:

sh 复制代码

$ python -m http.server -b "::"
Serving HTTP on :: port 8000 (http://[::]:8000/) ...

You may instruct the server to associate its home address (/) with a completely different directory by specifying the optional -d parameter:

sh 复制代码

$ python3 -m http.server -d ~/Pictures/
Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...

The -d option may be your only choice in some cases. For instance, if you try to start the HTTP server in a directory where you installed your Python interpreter, then you may face the following problem:

sh 复制代码

$ cd /usr/lib/python3.8/
$ python3 -m http.server
Traceback (most recent call last):
  ...
AssertionError: SRE module mismatch

You can work around this issue by changing your working directory so that Python will no longer find this module in the file system. Then, start the server using the -d option to point it back to the desired directory:

sh 复制代码

$ cd ..
$ python3 -m http.server -d /usr/lib/python3.8/
Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...
