Linux View MySQL installation path

First, view the file installation path

Since there is more than one place to install the software, all the paths (addresses) that are first said to view the file installation.

Take MySQL for example here. For example, I installed MySQL, but do not know where the files are installed, in which folders, you can use the following command to view all the file path
In Terminal input:

Whereis MySQL

Enter, if you installed MySQL, will show the file installation address, such as my display (the installation address may be different)

[[email protected] ~]# Whereis MySQL
MySQL:/usr/bin/mysql/usr/lib/mysql/usr/share/mysql/usr/share/man/man1/mysql.1.gz

Second, the path of the query running file (folder address)

If you just query the file's running file address, you can use the following command (or MySQL, for example):

which MySQL

Terminal display:

[[email protected] ~]# which MySQL
/usr/bin/mysql
