Although the old way of interrupting the boot process (init=/bin/bash) still works, it is no longer bulletproof and recommended. 'Systemd' uses 'rd.break' to interrupt the boot. Let's have a quick walk through the whole procedure.  +RHEL7 的世界发生了变化，重置 root 密码的方式也一样。虽然中断引导过程（init=/bin/bash）的旧方法仍然有效，但它不再是推荐的。“Systemd” 使用 “rd.break” 来中断引导。让我们快速浏览下整个过程。  -### Boot into the minimal mode +### 启动进入最小模式 -Reboot the system and press `e` while being on the kernel list page, before the autoboot starts the system automatically. You get into the edit mode. +重启系统并在内核列表页面在系统启动之前按下 `e`。你会进入编辑模式。 -### Interrupt the boot process +### 中断启动进程 -In the kernel string - at the end of the line starting `linux 16 /vmlinuz- ect` type `rd.break`. Then Ctrl+X to reboot. The system boots into the initial ram drive and it's mounted on /sysroot In this mode you are not required to type the password. +在内核字符串中 - 在以 “linux 16 /vmlinuz- ect” 结尾的行中输入 “rd.break”。接着 Ctrl+X 重启。系统启动进入初始化内存磁盘，并挂载在 /sysroot。在此模式中你不需要输入密码。 -### Remount the system so that it can read and write +### 重新挂载可以读写的系统 ``` switch_root:/# mount -o remount,rw /sysroot/ ``` -### Make /sysroot your root +### 使 /sysroot 成为根目录 ``` switch_root:/# chroot /sysroot ``` -The command line will change slightly. +命令行会稍微改变。 -### Change the root password +### 修改 root 密码 ``` sh-4.2# passwd ``` -### Load SELinux policy +### 加载 SELinux 策略 ``` sh-4.2# load_policy -i ``` -### Set context type on /etc/shadow file +###  在 /etc/shadow 中设置上下文类型 ``` sh-4.2# chcon -t shadow_t /etc/shadow ``` -Note: You could bypass the last 2 steps by creating an autorelabel file instead, but autorelabeling might take a long time. + +注意：你可以通过创建 autorelabel 文件略过最后两步，但是 autorelabel 会花费很长时间。 + ``` sh-4.2# touch /.autorelabel ``` -For that reason, and despite it is easier, it should be regarded as the 'lazy option', and is not recommended. -### Exit & reboot +因为这个原因，尽管它更简单，它应该作为“懒人选择”，而不是建议。 -Exit & reboot and log in with your new root password. +### 退出并重启 + +退出并重启并用新的 root 密码登录。 -------------------------------------------------------------------------------- via: https://linuxconfig.org/how-to-reset-the-root-password-in-rhel7-centos7-scientific-linux-7-based-systems 作者：[Rado Folwarczny][a] -译者：[译者ID](https://github.com/译者ID) +译者：[geekpi](https://github.com/geekpi) 校对：[校对者ID](https://github.com/校对者ID) 本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出
