SQL Optimization Tuner Report
Hi all,
I just started using WHM so bear with my noobness :).
I have a VPS from Godaddy 4vCPU 8 GB RAM 200GB SSD. It is currently running 4 Wordpress sites, but I am still migrating about 16 over from a similar specced shared server I used to have with godaddy (decided it was time for an upgrade from shared hosting).
Anyway, currently I'm about 7% RAM usage with the 4 sites, and I'm guessing this will go higher with the more sites I migrate over (they are all WordPress). I have already optimized the server using the tweak settings, but I wanted to see what the best settings for my server running MySQL 5.7 are. Here is the sql tuner report below:

-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
Control warning line(s) into /var/log/mysqld.log file
MySQL was started within the last 24 hours - recommendations may be inaccurate
Reduce your overall MySQL memory footprint for system stability
Dedicate this server to your database for highest performance.
Reduce or eliminate unclosed connections and network issues
Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found.
See https://dev.mysql.com/doc/internals/en/join-buffer-size.html
(specially the conclusions at the bottom of the page).
Performance schema should be activated for better diagnostics
Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: https://bit.ly/2TcGgtU
Variables to adjust:
*** MySQL's maximum memory usage is dangerously high ***
*** Add RAM before increasing MySQL buffer variables ***
query_cache_size (=0)
query_cache_type (=0)
query_cache_limit (> 1M, or use smaller result sets)
join_buffer_size (> 256.0K, or always use indexes with JOINs)
performance_schema = ON enable PFS
innodb_log_file_size should be (=6M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.

Hi @nicedood, Do you know if it's an OpenVZ or KVM VPS that you have purchased from GoDaddy? General performance of a KVM VPS will be much better. Is the bottleneck the database? Have you checked the slow queries log? If it was my VPS, I'd look at using Litespeed with LSCache to improve performance amongst other things unless I was certain where the bottleneck was. 0 -
Hi @ZenHostingTravis I don't think it specifies, I bought the 4vCPU listed here: Get a Managed VPS Hosting Solution - GoDaddy There really isn't a bottleneck, I just want to configure the performance before it gets to that point. I just want to prepare before it gets to that. I just did a quick google search on litespeed with lscache, but only wordpress plugins are popping up, Do you have a link that I can read more about this? Is there a simple command I can run in the terminal to install this on WHM? Thank you for your response :) 0 -
While some folks here might be able to provide you with information on optimizing MySQL we can't guarantee it. Your best course of action would be to enlist the assistance of a qualified system administrator. If you don't have one you might find one here: System Administration Services 0 -

Hi @nicedood, That's good that you're tweaking your server to get the best performance out of it. Kudos to you. You'd need to purchase a Litespeed license (they might offer a trial license) and you can install the LSCache plugin to a CMS such as Wordpress. It's relatively easy to install Litespeed from the command line and the Litespeed team provide good support but obviously it's always best to your testing on a non-production VPS. If you're interested in testing Nginx, there is a good plugin called Engintron that installs Nginx to cPanel and the author has written a lot of documentation around how to tweak mySQL for performance so you might be interested in reading that. cPanel is also working on an Nginx release soon. I'm sure @cPanelLauren can tell you more about that, if you're interested in learning more.0
