# PermitRootLogin yes

To:

PermitRootLogin no

TIPS:

• When you log on with the root account, if you only see the well number and enter bash, you can display it normally. log on to the account, host name, and home directory.
  

# Bash
[Root @ hostname ~] # Ls-lart

• Kill-9 0 after logging on to the server, use this command, the history command, will not record your operations. Cool enough.
