How to start mysql in Manjaro from terminal?

I had installed mysql using the following command

sudo pacman -Sy mysql

Earlier, I was using Lampp(Xampp for Linux) where I could start using the command

/opt/lampp/start start

I am not sure if I was running Xampp that way cause, it's been a long day I had used Lampp. Now, I want to run mysql (which I installed using sudo pacman -Sy mysql). I was looking at help also. But, I didn't find any start command.

mysql --help

The following groups are read: mysql mariadb-client client client-server client-mariadb
The following options may be given as the first argument:
--print-defaults          Print the program argument list and exit.
--no-defaults             Don't read default options from any option file.
The following specify which files/extra groups are read (specified before remaining options):
--defaults-file=#         Only read default options from the given file #.
--defaults-extra-file=#   Read this file after the global files are read.
--defaults-group-suffix=# Additionally read default groups with # appended as a suffix.

  -?, --help          Display this help and exit.
  -I, --help          Synonym for -?
  --abort-source-on-error 
                      Abort 'source filename' operations in case of errors
  --auto-rehash       Enable automatic rehashing. One doesn't need to use
                      'rehash' to get table and field completion, but startup
                      and reconnecting may take a longer time. Disable with
                      --disable-auto-rehash.
                      (Defaults to on; use --skip-auto-rehash to disable.)
  -A, --no-auto-rehash 
                      No automatic rehashing. One has to use 'rehash' to get
                      table and field completion. This gives a quicker start of
                      mysql and disables rehashing on reconnect.
  --auto-vertical-output 
                      Automatically switch to vertical output mode if the
                      result is wider than the terminal width.
  -B, --batch         Don't use history file. Disable interactive behavior.
                      (Enables --silent.)
  --binary-as-hex     Print binary data as hex
  --character-sets-dir=name 
                      Directory for character set files.
  --column-type-info  Display column type information.
  -c, --comments      Preserve comments. Send comments to the server. The
                      default is --skip-comments (discard comments), enable
                      with --comments.
  -C, --compress      Use compression in server/client protocol.
  -#, --debug[=#]     This is a non-debug version. Catch this and exit.
  --debug-check       Check memory and open file usage at exit.
  -T, --debug-info    Print some debug info at exit.
  -D, --database=name Database to use.
  --default-character-set=name 
                      Set the default character set.
  --delimiter=name    Delimiter to be used.
  -e, --execute=name  Execute command and quit. (Disables --force and history
                      file.)
  -E, --vertical      Print the output of a query (rows) vertically.
  -f, --force         Continue even if we get an SQL error. Sets
                      abort-source-on-error to 0
  -G, --named-commands 
                      Enable named commands. Named commands mean this program's
                      internal commands; see mysql> help . When enabled, the
                      named commands can be used from any line of the query,
                      otherwise only from the first line, before an enter.
                      Disable with --disable-named-commands. This option is
                      disabled by default.
  -i, --ignore-spaces Ignore space after function names.
  --init-command=name SQL Command to execute when connecting to MariaDB server.
                      Will automatically be re-executed when reconnecting.
  --local-infile      Enable/disable LOAD DATA LOCAL INFILE.
  -b, --no-beep       Turn off beep on error.

  -N, --skip-column-names 
                      Don't write column names in results.
  --sigint-ignore     Ignore SIGINT (CTRL-C).
  -o, --one-database  Ignore statements except those that occur while the
                      default database is the one named at the command line.
  --pager[=name]      Pager to use to display results. If you don't supply an
                      option, the default pager is taken from your ENV variable
                      PAGER. Valid pagers are less, more, cat [> filename],
                      etc. See interactive help (\h) also. This option does not
                      work in batch mode. Disable with --disable-pager. This
                      option is disabled by default.
  -p, --password[=name] 
                      Password to use when connecting to server. If password is
                      not given it's asked from the tty.

When I try to run

mysql -A

I get the following error

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (2)

I was just running the command for testing, I totally don't know what auto-rehash is.

mysql version is :

mysql Ver 15.1 Distrib 10.5.10-MariaDB, for Linux (x86_64) using readline 5.1

I had tried to run the command

sudo mysql -u root -p

It was asking me for password. I had tried three default passwords.

1. localhost
2. root
3. (empty)

All of them were returning the following error

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (2)

I had tried to start mysql using service command.

sudo service mysql start

Unfortunately, "service" application wasn't available. When I tried with systemctl I got the following error

Failed to enable unit: Unit file mysqld.service does not exist.

When I only run mysql directly. I got following error.

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (2)

I was trying to check /run/mysqld/mysqld.sock file. When I entered /run/ I noticed there was no mysqld folder. I had installed mysql from snapd.
