For a VM with 1GB memory running both MySQL and Apache, you'll need to configure MySQL to use an appropriate amount of memory to ensure optimal performance. Here's a sample
my.cnf configuration that you can start with:
[mysqld] # Basic Settings max_connections = 100 key_buffer_size = 16M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 8 # Performance Tuning table_open_cache = 64 sort_buffer_size = 512K read_buffer_size = 256K read_rnd_buffer_size = 512K join_buffer_size = 512K tmp_table_size = 16M max_heap_table_size = 16M query_cache_type = 1 query_cache_limit = 1M query_cache_size = 16M # InnoDB Settings innodb_buffer_pool_size = 256M innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 8M innodb_thread_concurrency = 8 innodb_flush_method = O_DIRECT # Logging log_error = /var/log/mysql/error.log slow_query_log = 1 slow_query_log_file = /var/log/mysql/slow_query.log long_query_time = 2 # Other Settings default_storage_engine = InnoDB character_set_server = utf8mb4 collation_server = utf8mb4_unicode_ci [mysqld_safe] log_error = /var/log/mysql/mysql_error.log pid_file = /var/run/mysqld/mysqld.pid [mysql] default_character_set = utf8mb4 [client] default_character_set = utf8mb4
Please note that these values are just examples and may need to be adjusted based on your specific workload and requirements. It's essential to monitor the server's performance and make further adjustments if needed.
After making changes to the
my.cnf file, restart MySQL to apply the new configuration.
Keep in mind that running both MySQL and Apache on a VM with limited memory can lead to resource constraints and potential performance issues. It's recommended to monitor the server's memory usage and consider upgrading the VM or allocating more resources if needed.
