General recommendations:
Control warning line(s) into /var/lib/mysql/onlinejyotish.com.err file

Restrict Host for user@% to user@SpecificDNSorIp
5 CVE(s) found for your MySQL release. Consider upgrading your version !
MySQL was started within the last 24 hours - recommendations may be inaccura te
Enable the slow query log to troubleshoot bad queries
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
Consider installing Sys schema from
mysql/mysql-sys
Before changing innodb_log_file_size and/or innodb_log_files_in_group read t his:
MySQL :: MySQL 5.7 Reference Manual :: 14.7.2 Changing the Number or Size of InnoDB Redo Log Files
Variables to adjust:
SET innodb_stats_on_metadata = OFF
query_cache_size (=0)
query_cache_type (=0)
join_buffer_size (> 128.0K, or always use indexes with JOINs)
tmp_table_size (> 16M)
max_heap_table_size (> 16M)
innodb_file_per_table=ON
innodb_buffer_pool_size (>= 278.8M) if possible.
innodb_log_file_size should be (=16M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.
