-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
/var/lib/mysql/xxx.exexexex.com.err is > 32Mb, you should analyze why or implement a rotation log strategy such as logrotate!
Control warning line(s) into /var/lib/mysql/xxx.exexexex.com.err file
Control error line(s) into /var/lib/mysql/xxx.exexexex.com.err file
Set up a Secure Password for user@host ( SET PASSWORD FOR 'user'@'SpecificDNSorIp' = PASSWORD('secure_password'); )
Restrict Host for user@% to user@SpecificDNSorIp
MySQL was started within the last 24 hours - recommendations may be inaccurate
Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
Adjust your join queries to always utilize indexes
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries which have no LIMIT clause
Performance schema should be activated for better diagnostics
Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: https://bit.ly/2TcGgtU
Variables to adjust:
query_cache_size (=0)
query_cache_type (=0)
query_cache_limit (> 1M, or use smaller result sets)
join_buffer_size (> 256.0K, or always use indexes with JOINs)
tmp_table_size (> 16M)
max_heap_table_size (> 16M)
performance_schema = ON enable PFS
innodb_buffer_pool_size (>= 9.3G) if possible.
innodb_log_file_size should be (=16M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.
