MySQL installation and configuration
Installation
|
Warning Make sure to install a supported version of MySQL Server and ODBC Connector. |
If you have already installed and configured MySQL, proceed to Configuration.
1.Before installing the database on Linux, add MySQL repository:
Debian, Ubuntu |
Run the following commands in the Terminal: a)wget https://dev.mysql.com/get/mysql-apt-config_0.8.15-1_all.deb b)sudo dpkg -i mysql-apt-config_0.8.15-1_all.deb See also: Adding the MySQL APT Repository |
CentOS, Red Hat, Fedora |
|
OpenSuse, SUSE Linux Enterprise Server |
2.After adding the MySQL repository update your local repository cache (e.g. on Debian run sudo apt-get update), and you can proceed with MySQL installation.
3.Installation of MySQL differs depending on the Linux distribution and version used:
Linux distribution: |
MySQL Server installation command: |
MySQL Server advanced installation: |
Debian, Ubuntu |
sudo apt-get install mysql-server |
https://dev.mysql.com/doc/refman/5.7/en/linux-installation-apt-repo.html |
CentOS, Red Hat, Fedora |
sudo yum install mysql-server |
https://dev.mysql.com/doc/refman/5.7/en/linux-installation-yum-repo.html |
OpenSuse, SUSE Linux Enterprise Server |
sudo zypper install mysql-community-server |
https://dev.mysql.com/doc/refman/5.7/en/linux-installation-sles-repo.html |
•Manual installation – download and install MySQL Community Server edition from: https://dev.mysql.com/downloads/mysql/
Configuration
1.Run the following command to open the my.cnf (my.ini for Windows installation) file in a text editor:
sudo nano /etc/mysql/my.cnf
If the file is not present, try /etc/my.cnf or /etc/my.cnf.d/community-mysql-server.cnf
2.Find the following configuration in the [mysqld] section of the my.cnf file and modify the values. If the parameters are not present in the file, add them to the [mysqld] section:
max_allowed_packet=33M
To determine your MySQL version, run the command: mysql --version
•For the supported versions MySQL 8.x, you must set the following variable:
olog_bin_trust_function_creators=1
oAlternatively, you can disable binary logging: log_bin=0
•For the supported versions of MySQL 8.x, 5.7 and 5.6.22 (and later 5.6.x):
oinnodb_log_file_size*innodb_log_files_in_group needs to be set to at least 200 MB (* denotes multiplication, the product of the two parameters must be > 200 MB. The minimum value for innodb_log_files_in_group is 2 and maximum value is 100, the value also has to be integer).
For example:
innodb_log_file_size=100M
innodb_log_files_in_group=2
•For MySQL 5.6.20 and 5.6.21:
oinnodb_log_file_size needs to be set to at least 200 MB (for example, innodb_log_file_size=200M), but not more than 3000 MB.
3.Save and close the file and enter the following command to restart the MySQL server and apply the configuration (in some cases, the service name is mysqld):
sudo service mysql restart
4.Run the following command to set up MySQL including privileges and password (this is optional and may not work for some Linux distributions):
/usr/bin/mysql_secure_installation
5.Enter the following command to check whether the MySQL server is running:
sudo service mysql status
