7. Update MySQL Configuration Parameters

   • Open the MySQL server configuration file:

     Copy

     sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

   • Add or update the following parameters under the [mysqld] section:

     Copy

     max_binlog_size              = 1G
     binlog_expire_logs_seconds   = 2592000
     group_concat_max_len         = 4294967295
     max_connections              = 600
     max_allowed_packet           = 1G
     bind-address                 = 0.0.0.0
     innodb_buffer_pool_size      = 8G

     Set bind-address=0.0.0.0 only if the MySQL server must accept remote connections (e.g., from an external application server).

     Adjust innodb_buffer_pool_size based on available memory. The recommended value is 50–70% of the total RAM.
