Hi,
I am having a nightmare with constant 504 Gateway errors. I have spent the last week trying to troubleshoot the website (checking plugins etc.) l am now looking at whether it is the server settings.
My dedicated server spec is as follows:
Usage
1% 6 CPU cores 1.98% / 100%
5% RAM 3.57GB / 64GB
27% Disk space - RAID 1 1080GB / 4000GB
My current my.cnf is as follows:
# For advice on how to change settings please see
# MySQL :: MySQL 5.7 Reference Manual :: 5.1.2 Server Configuration Defaults
[mysqld]
performance-schema=0
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
innodb_buffer_pool_size=134217728
max_allowed_packet=268435456
open_files_limit=80000
innodb_file_per_table=1
sql_mode=""
innodb_lock_wait_timeout=600
table_definition_cache=2400
I ran the following command as recommended on this forum:
perl mysqltuner.pl
This is the output result:

-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
Check warning line(s) in /var/log/mysqld.log file
Check error line(s) in /var/log/mysqld.log file
MySQL was started within the last 24 hours: recommendations may be inaccurate
name resolution is enabled due to cPanel doesn't support this disabled.
We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found.
See MySQL: Welcome
(specially the conclusions at the bottom of the page).
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries which have no LIMIT clause
Performance schema should be activated for better diagnostics
Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: MySQL :: MySQL 8.0 Reference Manual :: 15.6.5 Redo Log
Variables to adjust:
skip-name-resolve=0
join_buffer_size (> 256.0K, or always use indexes with JOINs)
tmp_table_size (> 16M)
max_heap_table_size (> 16M)
table_definition_cache (2400) > 40727 or -1 (autosizing if supported)
performance_schema=ON
innodb_buffer_pool_size (>= 9.1G) if possible.
innodb_log_file_size should be (=16M) if possible, so InnoDB total log file size equals 25% of buffer pool size.

My questions are:
1. Is there anything in those results that would be the cause of my 504 Gateway error and poor performance?
2. What should I change/add to my.cnf to improve the performance for my dedicated specification?
3. If this isn't something you'd recommend I try myself is there someone at Cpanel who can help me tune this and PHP settings to eradicate these problems and speed up performance and what is the cost?
I did try changing some settings but then when i saved it crashed so had to revert back to the default my.cnf as shown above.
I do hope you can help me as this is destroying my user experience.
Kind regards
I am having a nightmare with constant 504 Gateway errors. I have spent the last week trying to troubleshoot the website (checking plugins etc.) l am now looking at whether it is the server settings.
My dedicated server spec is as follows:
Usage
1% 6 CPU cores 1.98% / 100%
5% RAM 3.57GB / 64GB
27% Disk space - RAID 1 1080GB / 4000GB
My current my.cnf is as follows:
# For advice on how to change settings please see
# MySQL :: MySQL 5.7 Reference Manual :: 5.1.2 Server Configuration Defaults
[mysqld]
performance-schema=0
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
Check warning line(s) in /var/log/mysqld.log file
Check error line(s) in /var/log/mysqld.log file
MySQL was started within the last 24 hours: recommendations may be inaccurate
name resolution is enabled due to cPanel doesn't support this disabled.
We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found.
See MySQL: Welcome
(specially the conclusions at the bottom of the page).
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries which have no LIMIT clause
Performance schema should be activated for better diagnostics
Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: MySQL :: MySQL 8.0 Reference Manual :: 15.6.5 Redo Log
Variables to adjust:
skip-name-resolve=0
join_buffer_size (> 256.0K, or always use indexes with JOINs)
tmp_table_size (> 16M)
max_heap_table_size (> 16M)
table_definition_cache (2400) > 40727 or -1 (autosizing if supported)
performance_schema=ON
innodb_buffer_pool_size (>= 9.1G) if possible.
innodb_log_file_size should be (=16M) if possible, so InnoDB total log file size equals 25% of buffer pool size.

My questions are:
1. Is there anything in those results that would be the cause of my 504 Gateway error and poor performance?
2. What should I change/add to my.cnf to improve the performance for my dedicated specification?
3. If this isn't something you'd recommend I try myself is there someone at Cpanel who can help me tune this and PHP settings to eradicate these problems and speed up performance and what is the cost?
I did try changing some settings but then when i saved it crashed so had to revert back to the default my.cnf as shown above.
I do hope you can help me as this is destroying my user experience.
Kind regards
