Hello,

I have 2 virtual servers (VMware ESXi) and need help optimizing MySQL.

I quote below the results of mysqltuner.pl:


Server 1:

Code:
 >>  MySQLTuner 1.2.0 - Major Hayden <[email protected]>
 >>  Bug reports, feature requests, and downloads at [url]http://mysqltuner.com/[/url]
 >>  Run with '--help' for additional options and output filtering

-------- General Statistics --------------------------------------------------
[--] Skipped version check for MySQLTuner script
[OK] Currently running supported MySQL version 5.1.70-cll
[OK] Operating on 64-bit architecture

-------- Storage Engine Statistics -------------------------------------------
[--] Status: +Archive -BDB -Federated +InnoDB -ISAM -NDBCluster
[--] Data in MyISAM tables: 3G (Tables: 32860)
[--] Data in InnoDB tables: 127M (Tables: 1378)
[--] Data in MEMORY tables: 0B (Tables: 41)
[!!] Total fragmented tables: 175

-------- Security Recommendations  -------------------------------------------
[OK] All database users have passwords assigned

-------- Performance Metrics -------------------------------------------------
[--] Up for: 2d 10h 52m 7s (18M q [89.440 qps], 569K conn, TX: 116B, RX: 3B)
[--] Reads / Writes: 68% / 32%
[--] Total buffers: 2.3G global + 4.5M per thread (2000 max threads)
[OK] Maximum possible memory usage: 11.0G (81% of installed RAM)
[OK] Slow queries: 2% (449K/18M)
[OK] Highest usage of available connections: 3% (70/2000)
[OK] Key buffer size / total MyISAM indexes: 1.0G/909.8M
[OK] Key buffer hit rate: 99.9% (7B cached / 5M reads)
[OK] Query cache efficiency: 76.1% (9M cached / 12M selects)
[!!] Query cache prunes per day: 243852
[OK] Sorts requiring temporary tables: 0% (3K temp sorts / 742K sorts)
[!!] Joins performed without indexes: 88072
[!!] Temporary tables created on disk: 34% (474K on disk / 1M total)
[OK] Thread cache hit rate: 99% (70 created / 569K connections)
[!!] Table cache hit rate: 0% (4K open / 45M opened)
[OK] Open file limit used: 18% (9K/50K)
[OK] Table locks acquired immediately: 99% (5M immediate / 5M locks)
[OK] InnoDB data size / buffer pool: 127.2M/128.0M

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    Adjust your join queries to always utilize indexes
    Temporary table size is already large - reduce result set size
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
    query_cache_size (> 128M)
    join_buffer_size (> 1.0M, or always use indexes with joins)
    table_cache (> 4000)

Server 2:

[!!] InnoDB data size / buffer pool: 2.6G/8.0M

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    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 without LIMIT clauses
    Set thread_cache_size to 4 as a starting value
    Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
    key_buffer_size (> 1.1G)
    query_cache_size (>= 8M)
    join_buffer_size (> 128.0K, or always use indexes with joins)
    tmp_table_size (> 16M)
    max_heap_table_size (> 16M)
    thread_cache_size (start at 4)
    table_cache (> 64)
    innodb_buffer_pool_size (>= 2G)

Both Servers run cPanel RELEASE with CloudLinux.

I will pay $5 per server
dude :| you have missed at least one 0

few tips
#1
- lower max connections number
[OK] Highest usage of available connections: 3% (70/2000)
- optimize queries (slow, temporary tables and indexes)

#2
- lower max conn number
[OK] Highest usage of available connections: 7% (35/500)
- enable query cache
- increase key_cache_size to save value 1.1G
- set thread_cache_size something like 20 will do
- table_cache_size smth like 5000
- innodb buffer at least 2.6G
- optimize queries (slow, temp tables and indexes)

I have removed your original offer to pay for assistance with this issue. It's against the forum rules to use it as a marketplace. However, you are welcome to communicate to other users on this thread who are willing to assist you with your configuration at no cost. Or, if you prefer to pay for assistance from a system administrator, you can review our system administration services at:

cPanel Application Catalog - System Admin Services

Thank you.
