How to adjust default PHP-FPM settings

avinashpudota · June 30, 2021, 6:18am

Hi,

Currently i am manually adjusting pm.max_children at /etc/php/7.4/fpm/pool.d/domain.conf
The default value of pm.max_children is 8. How do i change this default value so any newly created domains or subdomains will inherit this value.

I hope this doesn’t make any difference. We have only one user on server and all the sub domains are added as domains to this user.

i would also like to find what is the optimal value for pm.max_children based on my configuration. I have 64 GB RAM and E3 processor with an SSD. There would be 200 to 300 users who login to chamilo LMS within 3 minutes interval. Like this we have 4 sub domains. Currently i am setting pm.max_children as 50. After login they will be redirected to another server from dashboard.

This is a new server which i am still setting up, so there is no way to find apache memory usage, i would just like to know what would be the best value and any settings i need to change.

**Please include as much information as possible in your issue report, such as t…he configuration of your server and any troubleshooting steps that you've already performed.** **NOTE: Do not include any personal or sensitive information, such as email addresses or passwords.** === ### In a few words, please describe the issue that you're experiencing: When rebuilding a user or after a Hestia upgrade where users are rebuilded, custom pool configurations are reset e.g. the below in /etc/php/phpversion/fpm/pool.d : pm pm.max_children pm.max_requests pm.process_idle_timeout There are cases that you need to amend the above values eg in high traffic websites. At least if not preserved then kept somewhere before upgrade/rebuild. But I strongly believe they should be preserved. ### What steps did you take when the issue occured? 1. Ex.: Click on the Web tab 2. Ex.: Click on Add Web Domain 3. Ex.: Attempted to add a domain and received an Internal Server Error. ### Expected behavior: Please enter your answer here (e.g. the web domain should have been added successfully). ### Operating system: Ubuntu 18.04 LTS ### Hestia Control Panel version: 1.1.1 ### Additional notes: If there is anything else that you'd like us to know about this issue, feel free to share here.
