I've installed MySQLTuner locally and it works on my local database.

When I try to run it on my Amazon RDS db it does not, it says my login credentials are invalid.

$ perl mysqltuner.pl --host testing-db.??????????.us-east-1.rds.amazonaws.com --port 3306 --user admin_un --password admin_pw --forcemem 7500
[--] Performing tests on testing-db.??????????.us-east-1.rds.amazonaws.com:3306
[!!] Attempted to use login credentials, but they were invalid

I'm able to myssql normally into the RDS db locally with.

mysql -h testing-db.??????????.us-east-1.rds.amazonaws.com -P 3306 -u admin_un -p

What could I be missing here?

UPDATE

The DB is on an AWS RDS db.m3.large instance which has 2 vCPUs and 7.5GiB of RAM. I've configured the MySQL configuration settings as suggested here in an RDS Parameter Group from the AWS console.

  • Do not use tuner scripts, they are usually not up-to-date and give weird suggestions which you should not try to apply without detailed knowledge of what it means. – jkavalik Sep 2 '15 at 12:05
  • If you provide me with (1) RAM size, (2) SHOW VARIABLES; (3) SHOW GLOBAL STATUS;, I will provide you with more (and better) recommendations than any of the tuners I have seen. – Rick James Sep 2 '15 at 16:24
  • @RickJames, Thanks I updated my question, also I have changed some of the MySQL Settings as suggested here for a Magento App – Holly Sep 2 '15 at 16:49
  • Nice link for Magento; reasonable advice. Working on your numbers now; may not get much info since the STATUS covers only 2 hour. – Rick James Sep 2 '15 at 21:28

Observations

Version: 5.6.23-log
7.5 GB of RAM
Uptime = 02:09:14; Please rerun SHOW GLOBAL STATUS after several hours.
You are not running on Windows.
Running 64-bit version
You appear to be running entirely (or mostly) InnoDB.

Important items

  • tmp_table_size = 64M

  • Review indexes and query formulation -- many are looking inefficient (by using tmp tables, etc)

  • To help in identifying the naughty queries, recommend setting long_query_time=2 and turning on the slowlog.

  • Replication is turned on, but the binlogs are being kept forever? Or does RDS purge them in some way I don't know about.

Details

( Innodb_buffer_pool_pages_free * 16384 / innodb_buffer_pool_size ) = 346,833 * 16384 / 5705302016 = 99.6% -- % of buffer pool free -- buffer_pool_size is bigger than working set; could decrease it (not critical)

( Uptime / 60 * innodb_log_file_size / Innodb_os_log_written ) = 7,754 / 60 * 128M / 7059968 = 2,456 -- Minutes between InnoDB log rotations Beginning with 5.6.8, this can be changed dynamically; be sure to also change my.cnf. -- (The recommendation of 60 minutes between rotations is somewhat arbitrary.) Adjust innodb_log_file_size. -- Very low activity on your server

( tmp_table_size ) = 265M -- Limit on size of MEMORY temp tables used to support a SELECT ( max_heap_table_size / _ram ) = 256M / 7680M = 3.3% -- Percent of RAM to allocate when needing MEMORY table for a temp table inside a SELECT (per temp table per some SELECTs). Too high may lead to swapping. (max_heap_table_size also user limits MEMORY tables.) -- Decrease both to, say, 1% of ram.

( local_infile ) = ON -- local_infile = ON is a potential security issue

( Created_tmp_disk_tables ) = 45,149 / 7754 = 5.8 /sec -- Frequency of creating disk "temp" tables as part of complex SELECTs ( Created_tmp_disk_tables / (Created_tmp_disk_tables + Created_tmp_tables) ) = 45,149 / (45149 + 113444) = 28.5% -- Percent of temp tables that spilled to disk -- Check the rules for temp tables being able to use MEMORY instead of MyISAM. It may be possible to make a minor schema or query change to avoid MyISAM. Better indexes and reformulation of queries can also help.

-- Decrease tmp_table_size to avoid running out of RAM. Perhaps no more than 64M.

( Select_scan ) = 50,953 / 7754 = 6.6 /sec -- full table scans ( Select_scan / Com_select ) = 50,953 / 700098 = 7.3% -- % of selects doing full table scan. (May be fooled by Stored Routines.) -- Add indexes / optimize queries (unless they are tiny tables)

( binlog_format ) = MIXED -- STATEMENT/ROW/MIXED. ROW is preferred; it may become the default.

( expire_logs_days ) = 0 -- How soon to automatically purge binlog (after this many days) -- Too large (or zero) = consumes disk space; too small = need to respond quickly to network/machine crash.

( slow_query_log ) = OFF -- Whether to log slow queries. (5.1.12) ( long_query_time ) = 10.000000 = 10 -- Cutoff (Seconds) for defining a "slow" query. -- Suggest ON and 2

( Com_flush ) = 12/HR ( Com_purge ) = 12/HR -- What is doing so many FLUSHes and PURGEs? These are both rarely-used commands.

You have the Query Cache half-off. You should set both query_cache_type = OFF and query_cache_size = 0 . There is (according to a rumor) a 'bug' in the QC code that leaves some code on unless you turn off both of those settings.

    Sorry for the late reply, thanks for your help. I set tmp_table_size to 256mb as it is what the MGT-Commerce blog post suggested, I'll change it :) – Holly Sep 10 '15 at 9:25

    I threw my 2-cents onto that page. – Rick James Sep 10 '15 at 20:25
