修改php.ini后phpinfo未生效，Scaleway主机CentOS+VestaCP配置求助

Hey there, let's work through this issue together—it's a super common gotcha with VestaCP since it manages multiple PHP versions and config overrides behind the scenes. Here's how to get your php.ini changes to stick:

1. Confirm Which PHP Version Your Site Is Using #

First, check the PHP Version listed at the top of your phpinfo() output. VestaCP often installs multiple PHP versions (like 7.4 or 8.1), and each has its own separate php.ini file—the /etc/php.ini you edited is likely for the CLI version, not the web/FPM version your site actually uses.

2. Locate the Correct php.ini File for Your PHP Version #

VestaCP stores PHP-FPM configs in version-specific directories. For example:

• For PHP 7.4: /etc/php/7.4/fpm/php.ini
• For PHP 8.1: /etc/php/8.1/fpm/php.ini

You can also run this SSH command to find the exact FPM config path for your active PHP version:

php-fpm<version> -i | grep "Loaded Configuration File"

(Replace <version> with your PHP version, e.g., php-fpm74 -i | grep "Loaded Configuration File")

3. Edit the Correct php.ini and Update max_execution_time #

Open the FPM-specific php.ini with your preferred editor (like nano):

nano /etc/php/<version>/fpm/php.ini

Find the max_execution_time line, uncomment it if needed, and set your desired value:

max_execution_time = 300 ; Adjust this to your needs, e.g., 300 seconds

Save and exit (for nano: press Ctrl+O, hit Enter, then Ctrl+X).

4. Check for VestaCP Panel Overrides #

VestaCP lets you set PHP settings per-site, which will override your php.ini changes:

1. Log into your VestaCP panel
2. Go to the Web tab, find your site, and click Edit
3. Scroll down to the PHP Settings section
4. Look for max_execution_time—if there's a value entered here, delete it (or set it to your desired value) to let the php.ini take effect
5. Save the changes

5. Restart PHP-FPM to Apply Changes #

Your new config won't take effect until you restart the PHP-FPM service. Run the appropriate command for your PHP version:

# For PHP 7.4
systemctl restart php-fpm74

# For PHP 8.1
systemctl restart php-fpm81

# Generic fallback if you're unsure
systemctl restart php-fpm

6. Verify the Fix #

Refresh your phpinfo() page and check two key values:

• Loaded Configuration File: Should now show the path to the FPM php.ini you edited
• max_execution_time: Should display your updated value

Bonus: Check for Pool Config Overrides #

If it's still not working, check your site's PHP-FPM pool config (VestaCP creates these per domain):

nano /etc/php/<version>/fpm/pool.d/<your-domain>.conf

Look for lines like php_admin_value[max_execution_time] = 60—if present, this will override php.ini. Either comment it out (add a ; at the start) or update the value to match your php.ini setting, then restart PHP-FPM again.
