Add PATH environment variables to Centos

Add the PATH environment variable. There are 1st methods:
[Root @ lx_web_s1 ~] # Export PATH =/usr/local/webserver/mysql/bin: $ PATH

View again:

[Root @ lx_web_s1 ~] # Echo $ PATH
/Usr/local/webserver/mysql/bin:/usr/local/webserver/mysql/bin/:/usr/kerberos/sbin:/usr/kerberos/bin: /usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

The PATH is successfully added.

The PATH of the above method disappears after the terminal is closed. Therefore, we recommend that you modify the PATH by editing/etc/profile. You can also modify the. bashrc (that is, ~) in the home directory :~ /. Bashrc ).

2nd methods:
# Vim/etc/profile
At the end, add:
Export PATH = "/usr/local/webserver/mysql/bin: $ PATH"
Save, exit, and run:
# Source/etc/profile
If no error is reported, the operation is successful.
