I recently started to learn about linux. as a newbie, I want to write a blog to record my learning experience and count it as a note. I encourage you to not talk much about it. The init method is described here.

 

Step 1: Press the keyboard to go to the following menu

Step 2: select the first item and press the e key to modify it (at the boot option)

Step 3: Find ro,

Step 4: change ro to rw init =/bin/sh

Step 5: As shown in, delete the rhgb quiet in the last and second rows of this section, press Ctrl + X to save and start the system.

Step 6: change the root password

# Passwd root # change the password, and then prompt to enter a new password and confirm the password again

# Touch/. autorelabel # It is said that selinux updated the label after restarting

# Exec/sbin/init # Start the init process normally

 

Note: If you perform the above command line operations in Chinese mode, garbled characters may occur. the solution is as follows:

$ Echo $ LANG (display the current language) (the first dollar sign is a system symbol and does not need to be edited by yourself. it is # Under root permission #)

$ LANG = en_US (English, Chinese: zh_CN)

$ Echo $ LANG (if you execute the first command again, it will show that you are using en_US, indicating English), OK, success
