After this editing inside the file is done, we can save the file and in order to match the port number of our own, we will change and replace the value of the MySQL port variable.Īfter that, you will have to restart the mysql or MariaDB and then verify the configuration of MariaDB and mySQL for port verification by making the use of the command ss or netstat which can be used by typing in either of the following commands. Here, we will have to search for the section inside which we will look at the port specification which let’s change it for now to 12345 as can be seen from the above image. Vi /(opt or etc)/(mysql or mariadb)/ /50-server.cnf that will open up the configuration file on your command prompt itself as shown in the below image – Make the use of vi command shown in the below example command statement to change the configured port address for the MariaDB database server. Further, if we want to change the default port used in MariaDB in a Linux platform then we can follow the below steps – The port can be used in the MariaDB database server to establish the connection as demonstrated in the above two commands of mysql connection establishment. mariadb port examples / Use the command – That results in the same output and execution as shown below – Mysql -h 235.26.8.108 -u payal -p password educbaDatabase -P 3000 Alternatively, the above command can also be used by specifying the port number with capital P option as shown below – The database with which the connection would be established is educbaDatabase present in our MariaDB database server. The user payal will be considered the supplied password will be taken into account and the port address which needs to be reached and established the connection will be 3000 which should be empty and available to use before this command is executed. The output of the execution of the above command is as shown below where the connection has been established with MariaDB database server configured at 3000 port number – Mysql -h 235.26.8.108 -u payal -p password educbaDatabase -port 3000 –port = address of port number or -P portNumber can be used to specify any other port with which to connect if the default 3306 port address is not used.įor example, when we use the below command – The connection is established between client and server but the connection is not connected to a particular database present on the server. User is the login name of ODBC on windows platform or login name of Unix. When you go for establishing the connection between MySQL client and MariaDB server the default command used is shown below.Īfter typing the above command, the default parameters taken from the configuration file are as follows – In MySQL, you will externally need to open port 3306 and set up it manually. Further that the TCP connections can only be opened through port address 3306. When we install the MariaDB software which has a trial installer version the port number 3306 is opened automatically which is an inbound rule. To check the logs in case if the connection is not established between the MariaDB database server and MySQL client, we can check the log file which tells us about the errors or the reasons for which the MariaDB server was started or stopped the log file can be found in the directory structure having the path opt/bitnami/mariadb/(data or logs)/ mysqld.log which has all the logged details in it. When using the Linux system package the my.cnf configuration file can be founded in the folder opt/bitnami/mariadb/conf/my.cnf file directory. cnf which is located inside the opt/bitnami/mariadb folder. The name of the configuration file in which all the default values to different options and parameters are listed is my. We can change the default port number address by some other number as per our requirements by accessing the configuration file and editing and modifying the same or by using the commands from the command prompt. MariaDB port is used for the same purpose. Port is basically a number given to a particular socket end where a task can communicate by establishing the connection. The MariaDB port number by default is 3306. Hadoop, Data Science, Statistics & others What is MariaDB port?
