MySQL is very popular opensource database. MySQL is created by MySQL AB a Swedish company and then bought by Sun. Sun is bought by Oracle and MySQL is currently owned by Oracle. MySQL is very popular at opensource community. In this post we will look how to list databases in MySQL.
Check MySQL Service Status
We need to be sure that MySQL daemon is running we will check with following systemctl command.
$ systemctl status mysql
Connect MySQL Server
We will use mysqlserver tools to connect MySQL daemon. mysql is most used command line tool to connect and manage MySQL server. We will connect server by running mysql command with sudo which means with root privileges.
$ sudo mysql -u root
Other way to connect MySQL daemon is providing password with -p parameter
$ mysql -u root -p
MySQL List/Show Databases
We will usage MySQL command show databases to list databases. Using semicolon at the end of the command is important otherwise the command will fail.
mysql> show databases;
List Databases From Bash
We can list MySQL databases without entering mysql tool command line through bash. We will use similar command to connect MySQL database but providing show database command as parameter. We will use MySQL show databases.
$ sudo mysql -u root -h localhost -e 'show databases;'
We have issued mysql command with -e parameter. show databases; runs as a mysql connect in the mysql shell.
$ sudo mysql -u root -h 192.168.122.211 -e 'show databases;'
Here is eveything is similar to the previous example except hostname which is provieded as -h 192.168.122.211. We provide hostname as remote host not localhost. To connect remote host firewall must give access to the port and MySQL daemon should be listening specified IP’s interface.
