具体操作步骤
1.首先我们建立一个账户,设置密码
[root@VM_0_13_centos home]# useradd 123 [root@VM_0_13_centos home]# passwd 123 Changing password for user better407. New password: BAD PASSWORD: it is WAY too short BAD PASSWORD: is too simple Retype new password: passwd: all authentication tokens updated successfully.
2.运行visudo工具编辑/etc/sudoers 文件
[root@VM_0_13_centos /]# visudo ## ## Allow root to run any commands anywhere root ALL=(ALL) ALL ## Allows members of the 'sys' group to run networking, software, ## service management apps and more. # %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS ## Allows people in group wheel to run all commands #在此添加 # %wheel ALL=(ALL) ALL 123 ALL=(ALL) ALL
3.将123账户添加到root用户组
[root@VM_0_13_centos home]# usermod -aG root 123
4.执行到su命令切换到新建的用户123
[root@VM_0_13_centos /]# su 123 bash-4.1$ groups 123 root
