linux+whereis+php path is incorrect

When using a Linux system, we often need to use the command line to perform various operations. Among them, using the whereis command to find the file path is one of the common operations. However, sometimes we find that the path returned by the whereis command is incorrect, resulting in the failure to execute the corresponding program correctly. This article will introduce how to solve the problem where the whereis command returns an incorrect php path in a Linux system.

1. Check the PHP installation path

Before solving the problem, we first need to confirm whether the PHP installation path is correct. We can use which command to view the installation path of PHP. Enter the following command in the terminal:

which php

If the output is /usr/bin/php, it means that the installation path of PHP is correct. If the output result is empty or another path, it means that the PHP installation path is wrong.

2. Use whereis to find the PHP path

Use the whereis command to find the binary, source code and help document paths of the program. Enter the following command in the terminal:

whereis php

The installation path of PHP will be displayed, for example:

php: /usr/bin/php /usr/share/php /usr/share/man/man1/php.1.gz

If the path returned by the whereis command is incorrect, for example, only /usr/share/ will be returned php or other paths, it means that the path specified in the PHP configuration file is incorrect.

3. Modify the path in the configuration file

The path information of PHP is generally stored in the configuration file. We can solve the problem of incorrect return path of whereis command by modifying the configuration file. Enter the following command in the terminal to edit PHP's configuration file (root permissions are required):

sudo nano /etc/php/php.ini

In the configuration file, look for the following path-related options:

; UNIX: "/path1:/path2"
; include_path = ".:/usr/share/php"

where include_path specifies PHP's path. We can change it to the correct path, such as /usr/bin/php. After modification, the content of the configuration file is as follows:

; UNIX: "/path1:/path2"
include_path = ".:/usr/bin/php"

After the modification is completed, save and close the file.

4. Restart the Apache server

If you are using the Apache server to run PHP, after modifying the PHP configuration file, you need to restart the Apache server for the modification to take effect. Enter the following command in the terminal to restart the Apache server:

sudo systemctl restart httpd

After the restart is complete, use the whereis command again to find the PHP path, and the correct path should be returned.

Summary

In the Linux system, the whereis command returns an incorrect php path, which may be caused by an incorrect PHP path configuration. To solve this problem, we need to confirm whether the installation path of PHP is correct, use the whereis command to find the path, modify the path information in the configuration file, and restart the Apache server to make the modification effective. These operations can all be performed in the terminal and only require some simple commands to solve the problem.
