How to grant root permissions to ordinary users in centos

Methods to grant root permissions to ordinary users:

1. To add a user, first use the adduser command to add an ordinary user. The command is as follows:

#adduser tommy      //添加一个名为tommy的用户
#passwd tommy       //修改密码
Changing password for user tommy.
New UNIX password:                //在这里输入新密码
Retype new UNIX password:         //再次输入新密码
passwd: all authentication tokens updated successfully.

2. Modify the /etc/sudoers file, find the root user line, and add a line under root, as shown below:

## Allow root to run any commands anywhere
root    ALL=(ALL)     ALL
tommy   ALL=(ALL)     ALL
