Debian7 sudo is invalid

Today, a group of servers added new users. After configuring the sudoers file used by The sudo command, I found that sudo on a server did not take effect. Why did sudo become invalid? The first occurrence occurs as follows:

$ Sudo ifconfig

Sudo: ifconfig: Command not found

$ Sudo fdisk-l

Sudo: fdisk: Command not found

How can I modify the configuration file and restart all servers? sudo does not work for common users. After a while, I finally found that it had something to do with environment variables. The solution is as follows:

1. When a single common user

(1) After logging on to a common user, find the. profile file. Be careful.

$ LS-Al

(2) edit the file. Profile

$ Vim. Profile # Add the following content:

Path = "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

Export path

(3) test: $ sudo ifconfig # Show OK

2. If your system has multiple common users

(1) Use the root user

# Vim/etc/profile # Add/sbin to the path variable after else

If ["'id-U'"-EQ 0]; then

Path = "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

Else

Path = "/usr/local/bin:/usr/local/games:/usr/games:/sbin"

Fi

Export path

# Source/etc/profile

(3) test. If the remote connection is required, log out and log on again.

### Description:Add/sbin because ifconfig fdisk and other commands are all here!
