Hello Everyone,

I need a mysql optimization with my server...WordPress installation on my website.

My server Properties:
Dell R730
2 x E5-2620 V3 CPU
32 GB Ram
Centos 7

I use wordpress script.
instant hit: 1k
daily visitors: 40.000 Unique

Code:
-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -

MySQL Version 5.6.27 x86_64

Uptime = 4 days 3 hrs 59 min 58 sec
Avg. qps = 292
Total Questions = 105160420
Threads Connected = 10

Server has been running for over 48hrs.
It should be safe to follow these recommendations

To find out more information on how each of these
runtime variables effects performance visit:
http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html
Visit http://www.mysql.com/products/enterprise/advisors.html
for info about MySQL's Enterprise Monitoring and Advisory Service

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10.000000 sec.
You have 0 out of 105160450 that take longer than 10.000000 sec. to complete
Your long_query_time seems to be fine

BINARY UPDATE LOG
The binary update log is NOT enabled.
You will not be able to do point in time recovery
See http://dev.mysql.com/doc/refman/5.6/en/point-in-time-recovery.html

WORKER THREADS
Current thread_cache_size = 1024
Current threads_cached = 33
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 12
Historic max_used_connections = 45
The number of used connections is 9% of the configured maximum.
You are using less than 10% of your configured max_connections.
Lowering max_connections could help to avoid an over-allocation of memory
See "MEMORY USAGE" section to make sure you are not over-allocating

INNODB STATUS
Current InnoDB index space = 480 K
Current InnoDB data space = 688 K
Current InnoDB buffer pool free = 99 %
Current innodb_buffer_pool_size = 2.00 G
Depending on how much space your innodb indexes take up it may be safe
to increase this value to up to 2 / 3 of total system memory

MEMORY USAGE
Max Memory Ever Allocated : 4.49 G
Configured Max Per-thread Buffers : 875 M
Configured Max Global Buffers : 4.41 G
Configured Max Memory Limit : 5.26 G
Physical Memory : 31.15 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 324 M
Current key_buffer_size = 2.00 G
Key cache miss rate is 1 : 17506
Key buffer free ratio = 78 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere

QUERY CACHE
Query cache is enabled
Current query_cache_size = 256 M
Current query_cache_used = 94 M
Current query_cache_limit = 8 M
Current Query cache Memory fill ratio = 36.95 %
Current query_cache_min_res_unit = 4 K
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 128 K
Current read_rnd_buffer_size = 256 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 1.00 M
You have had 1172 queries where a join could not use an index properly
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.

Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.

OPEN FILES LIMIT
Current open_files_limit = 65536 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine

TABLE CACHE
Current table_open_cache = 3072 tables
Current table_definition_cache = 2048 tables
You have a total of 479 tables
You have 973 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 128 M
Current tmp_table_size = 128 M
Of 5561736 temp tables, 18% were created on disk
Created disk tmp tables ratio seems fine

TABLE SCANS
Current read_buffer_size = 128 K
Current table scan ratio = 880 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 33
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'
If you have a high concurrency of inserts on Dynamic row-length tables
consider setting 'concurrent_insert=ALWAYS'.

Can you help me please?

Hello :)

Have you tried implementing the changes suggested in the output of the tuner script you ran?

Thank you.

You may need to consult with a qualified system administrator or MySQL specialist for additional tweaks to your MySQL configuration if you are still unhappy with the results. You can find a list of system administration services at:

Thank you.
