ubuntu中增加用户级sudo权限设置

今天公司IT要求在我的一台server上给他新建一个用户并需要sudo权限，各种百度后完成，把步骤记录下来备忘。

1 添加用户命令： useradd

Usage: useradd [options] LOGIN
       useradd -D
       useradd -D [options]

Options:
  -b, --base-dir BASE_DIR       base directory for the home directory of the
                                new account
  -c, --comment COMMENT         GECOS field of the new account
  -d, --home-dir HOME_DIR       home directory of the new account
  -D, --defaults                print or change default useradd configuration
  -e, --expiredate EXPIRE_DATE  expiration date of the new account
  -f, --inactive INACTIVE       password inactivity period of the new account
  -g, --gid GROUP               name or ID of the primary group of the new
                                account
  -G, --groups GROUPS           list of supplementary groups of the new
                                account
  -h, --help                    display this help message and exit
  -k, --skel SKEL_DIR           use this alternative skeleton directory
  -K, --key KEY=VALUE           override /etc/login.defs defaults
  -l, --no-log-init             do not add the user to the lastlog and
                                faillog databases
  -m, --create-home             create the user's home directory
  -M, --no-create-home          do not create the user's home directory
  -N, --no-user-group           do not create a group with the same name as
                                the user
  -o, --non-unique              allow to create users with duplicate
                                (non-unique) UID
  -p, --password PASSWORD       encrypted password of the new account
  -r, --system                  create a system account
  -R, --root CHROOT_DIR         directory to chroot into
  -s, --shell SHELL             login shell of the new account
  -u, --uid UID                 user ID of the new account
  -U, --user-group              create a group with the same name as the user
  -Z, --selinux-user SEUSER     use a specific SEUSER for the SELinux user mapping

我就用了 useradd -m itadmin

这样创建了用户itadmin并在home路径下创建了itadmin的文件夹。

2 设置密码

passwd

具体是passwd itadmin,然后会提示两次输入密码，两次密码相同就可以设置密码成功了。

3 赋予sudo权限。

在 /etc下找到文件/etc/sudoers，用vim打开，在root ALL=(ALL) ALL
下添加一行 itadmin ALL=(ALL) ALL

即可。
