root 账号不能登录的解决方法

默认系统 root 登录图形界面，出现登录失败。解决方法如下：

1，登录普通用户, 打开终端执行命令, 使用su root或sudo -i切换到root用户(必须)

su root

按照提示输入密码即可切换用户。

若root账户密码忘记，使用如下命令重设后再切换。

sudo passwd root

2，在终端中输入如下命令，打开文件

gedit /etc/pam.d/gdm-autologin

将打开的文件中第三行前加#，如下注释掉语句 “auth required pam_succeed_if.so user != root

quiet_success” #%PAM-1.0 auth requisite pam_nologin.so #auth required pam_succeed_if.so user != root quiet_success auth optional pam_gdm.so auth optional pam_gnome_keyring.so auth required pam_permit.so @include common-account #SELinux needs to be the first session rule. This ensures that any #lingering context has been cleared. Without this it is possible #that a module could execute code in the wrong domain. session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so close session required pam_loginuid.so #SELinux needs to intervene at login time to ensure that the process #starts in the proper default security context. Only sessions which are #intended to run in the user's context should be run after this. session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so open session optional pam_keyinit.so force revoke session required pam_limits.so session required pam_env.so readenv=1 session required pam_env.so readenv=1 user_readenv=1 envfile=/etc/default/locale @include common-session session optional pam_gnome_keyring.so auto_start @include common-password

3，保存并退出,继续在终端执行

gedit /etc/pam.d/gdm-password

将打开的文件中第三行语句加#注释掉，如下

#%PAM-1.0 auth requisite pam_nologin.so #auth required pam_succeed_if.so user != root quiet_success @include common-auth auth optional pam_gnome_keyring.so @include common-account #SELinux needs to be the first session rule. This ensures that any #lingering context has been cleared. Without this it is possible #that a module could execute code in the wrong domain. session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so close session required pam_loginuid.so #SELinux needs to intervene at login time to ensure that the process #starts in the proper default security context. Only sessions which are #intended to run in the user's context should be run after this. #pam_selinux.so changes the SELinux context of the used TTY and configures #SELinux in order to transition to the user context with the next execve() #call. session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so open session optional pam_keyinit.so force revoke session required pam_limits.so session required pam_env.so readenv=1 session required pam_env.so readenv=1 user_readenv=1 envfile=/etc/default/locale @include common-session session optional pam_gnome_keyring.so auto_start @include common-password

4，保存并退出。在终端继续执行

gedit /root/.profile

将打开的文件中“mesg n 2> /dev/null || true” 改为

tty -s&&mesg n 2> /dev/null || true

5，保存并退出。

6，重启电脑，即可以root用户登录
