CentOS7创建新用户

1、创建用户

useradd querylog

2、设置密码

passwd queylog

3、授权sudo权限

查找sudoers文件位置 whereis sudoers

查看权限 ls -l /etc/sudoers

 

修改文件为可编辑 chmod -v u+w /etc/sudoers

编辑文件 vim /etc/sudoers

收回权限 chmod -v u-w /etc/sudoers

查看权限 ls -l /etc/sudoers

第一次使用sudo会有提示

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.
