# PHP-FPM config directory
|
|
|
|
## General
|
|
|
|
* Add you custom php-fpm.conf files into this directory.
|
|
* Only files ending by `.conf` will be enabled
|
|
* Only files ending by `.conf` are ignored by git
|
|
|
|
|
|
## Example files
|
|
|
|
This directory also holds three example files:
|
|
|
|
| File | Description |
|
|
|---------------------------------|---------------------------------------------|
|
|
| `devilbox-fpm.conf-default` | Represents current PHP-FPM default settings |
|
|
| `devilbox-fpm.conf-pm_dynamic` | Example settings for dynamic workers |
|
|
| `devilbox-fpm.conf-pm_ondemand` | Example settings for ondemand workers |
|
|
|
|
* Do not edit these example files!
|
|
* Copy them to a new file (in case you want to use them)
|
|
|
|
|
|
## Worker configuration
|
|
|
|
When changing worker processes or scheduler, the following commands will come in handy
|
|
to monitor number of processes and memory consumption.
|
|
|
|
```bash
|
|
# Show current PHP-FPM child memory consumption in MB
|
|
ps -ylC php-fpm --sort:rss | awk '!/RSS/ { s+=$8 } END { printf "%dM\n", s/1024 }'
|
|
|
|
# (repeatedly) show current PHP-FPM child memory consumption in MB
|
|
watch --interval=1 "ps -ylC php-fpm --sort:rss | awk '"'!'"/RSS/ { s+=\$8 } END { printf \"%dM\n\", s/1024 }'"
|
|
|
|
# (repeatedly) Current number of PHP-FPM childs
|
|
watch --interval=1 "ps auxw | grep -E 'php-(cgi|fpm)' | grep -vE 'grep|master' | wc -l"
|
|
```
|
|
|
|
|
|
## Overwriting
|
|
|
|
If multiple `.conf` files are present in this directory specifying different values for the
|
|
same settings, the last file (alphabetically by filename) will overwrite any previous values.
|
|
|
|
|
|
## Compatibility
|
|
|
|
**Note:**
|
|
|
|
PHP-FPM 5.2 uses XML-style configuration and does not allow includes.
|
|
If you want to change php-fpm.conf for PHP-FPM 5.2 you need to adjust the main configuration file.
|
|
|
|
See `php-fpm-5.2/` directory.
