-------- Recommendations -------------------------------------------------------                                       --------------------
General recommendations:
    Control warning line(s) into /var/lib/mysql/server.net.err fil                                       e
    Control error line(s) into /var/lib/mysql/server.net.err file
    MySQL started within last 24 hours - recommendations may be inaccurate
    Configure your accounts with ip or subnets only, then update your configurat                                       ion with skip-name-resolve=1
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries which have no LIMIT clause
    Set thread_cache_size to 4 as a starting value
    Performance should be activated for better diagnostics
    Consider installing Sys schema from https://github.com/mysql/mysql-sys
    Read this before changing innodb_log_file_size and/or innodb_log_files_in_gr                                       oup: http://bit.ly/2wgkDvS
Variables to adjust:
    query_cache_size (=0)
    query_cache_type (=0)
    query_cache_limit (> 1M, or use smaller result sets)
    tmp_table_size (> 16M)
    max_heap_table_size (> 16M)
    thread_cache_size (start at 4)
    performance_schema = ON enable PFS
    innodb_log_file_size should be (=16M) if possible, so InnoDB total log files                                        size equals to 25% of buffer pool size.
    innodb_buffer_pool_instances (=1)

I added them. my.cnf . I added them. This time it gives an error.

Code: [Select]

#
# This group is read both both by the client and the server
# use it for options that affect everything
#
[client-server]

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d
[mysqld]
 query_cache_size (=0)
    query_cache_type (=0)
    query_cache_limit (> 1M)
    tmp_table_size (> 16M)
    max_heap_table_size (> 16M)
    thread_cache_size (4)
    performance_schema = ON
    innodb_log_file_size should be (=16M)
    innodb_buffer_pool_instances (=1)

You need to add query_cache_size (=0) as query_cache_size =0. SO it will look like

[mysqld]
 query_cache_size =0


Adjust the other variables same like this.
