FreeBSD 为用户赋予 root 权限

Prerequisite

FreeBSD 14.2

以 root 登录终端进行操作

实践操作

将用户添加到 wheel 组

pw usermod microcharon -G wheel

验证用户是否已添加到 wheel 组

root@freebsd-test:~ # id microcharon
uid=1001(microcharon) gid=1001(microcharon) groups=1001(microcharon),0(wheel)

确保 /etc/pam.d/su 配置正确

确保这行未被注释

auth            requisite       pam_group.so            no_warn group=wheel root_only fail_safe

root@freebsd-test:~ # cat /etc/pam.d/su
#
#
# PAM configuration for the "su" service
#

# auth
auth            sufficient      pam_rootok.so           no_warn
auth            sufficient      pam_self.so             no_warn
auth            requisite       pam_group.so            no_warn group=wheel root_only fail_safe ruser
auth            include         system

# account
account         include         system

# session
session         required        pam_permit.so

使用 su 或 sudo 切换至 root

默认情况使用 su -

microcharon@freebsd-test:~ $ su -
Password:

若使用 sudo，则需要安装和配置 sudo

pkg install sudo

配置 sudoers 文件

visudo

添加用户权限，找到以下行并取消注释

## Uncomment to allow members of group wheel to execute any command
# %wheel ALL=(ALL:ALL) ALL
%wheel ALL=(ALL:ALL) ALL

使用 sudo

sudo -i
