The git path is not passing when rooting.

The default setting for CentOS (which I confirm with 7) is /sbin:/bin:/usr/sbin/:/usr/bin due to the secure_path setting of sudoers, the sudo configuration file.

In order to enable /usr/local/bin/git to be used in the same operational manner as the question, one of the following methods should be used:In addition, if it is not sudo-s, sudo can take over the current environment variable PATH with the -E option.

• Use sudo su- instead of sudo-s
• Use su or su- instead of
• sudo-s (root password becomes root)
Enter
• sudo visudo to edit sudoers and set the Defaults secure_path line

For bash, set the environment variable PATH to pass the path.
The bash documentation reads:

PATH
Search path for the command. A colonized list of directories where the shell searches for commands (see command execution below). A directory name with a length of 0 during PATH indicates the current directory. An empty directory name can be either two colons side by side or represented by a leading or trailing colon. The default path is system dependent and is configured by the system administrator who installed bash. The typical value is `/usr/gnu/bin:/usr/local/bin:/usr/ucb:/bin:/usr/bin'.

Use the export command to set the environment variable. Add /usr/local/bin separated by /usr/local/bin

#exportPATH=$PATH:/usr/local/bin
# which git
/usr/local/bin/git

The value set by the export command is discarded when logged off, so it is written in through /.bashrc.

#vim to /.bash_profile
(omitted)
export PATH=$PATH:/usr/local/bin

sudo-s or manually load to reflect.

#.~/.bashrc←Read manually
# which git
/usr/local/bin/git

$sudo-s
# which git
/usr/local/bin/git
