This article is an introductory note I wrote years ago when I first started using Linux. The content is for reference only.

System installation

Mounting suggestions:

Linux requires only two basic partitions/and swap;

If/enough, you can put a lot of things on your desktop without compromising the speed of getting into Linux.

If you want to install a lot of software it is best to allocate /usr;

To be a server, it is best to allocate a large /var;

Note:

1 ⃣ ️. / boot:

New versions after 2018 can be divided;

You can allocate 10MB to 100MB

If the hard disk does not support LBA mode, you are advised to mount /boot to the first partition for safety.

2 ⃣ ️. Swap:

The first few service configurations:

• checktelnetWhether the service is started:

# chkconfig telnet --list
Copy the code

• Start thetelnetServices:

# chkonfig telnet on
Copy the code

After Telnet is enabled, you can use “> Telnet $IP” in Win to connect to Linux.

• inspectionFTPCurrent service Status:

# service vsftpd status 
Copy the code

• openFTPServices:

# service vsftpd start
Copy the code

The system switches

$sudo XXX = $sudo XXX = $sudo XXX = $sudo XXX

• Shut down the system:

Sync # init 0 or shutdown -n or haltCopy the code

• Restart the system:

# sync # init 6 or shutdown -rnCopy the code

• Exit current user login:

$ exit
Copy the code

Linux exit is similar to Windows logout;

• View the current virtual terminal:

$tty /dev/tty2 # virtual terminal 2Copy the code

• Switching terminal:

{Ctr + Alt + Fn}
Copy the code

Where n = {1, 2, 3… ,7}, for tty N.

Switch to graphics terminal (also a TTY) :

{Ctr + Alt + F7}
Copy the code

• Clear the screen:

$ clear
Copy the code

• Find all shells in the system:

$ cat /etc/shells
Copy the code

• Switch shell:

$KSH # Switch to Korn ShellCopy the code

You can enter a non-existent command (such as OK) on the command line to determine the user’s current shell.
