In Drupal 8, it will be better if we can enable OPCache.
How to enable OPCache in my localhost ?
I am using xampp v3.2.1 & windows 7.
With XAMPP version xampp-win32-5.6.14-4-VC11 I've added, after the section [dba],
; Determines if Zend OPCache is enabled
; Determines if Zend OPCache is enabled for the CLI version of PHP
; The OPcache shared memory storage size.
; The amount of memory for interned strings in Mbytes.
; The maximum number of keys (scripts) in the OPcache hash table.
Only numbers between 200 and 100000 are allowed.
; The maximum percentage of "wasted" memory until a restart is scheduled.
; When this directive is enabled, the OPcache appends the current working
; directory to the script key, thus eliminating possible collisions between
; files with the same name (basename). Disabling the directive improves
; performance, but may break existing applications.
; When disabled, you must reset the OPcache manually or restart the
; webserver for changes to the filesystem to take effect.
; How often (in seconds) to check file timestamps for changes to the shared
; memory storage allocation. ("1" means validate once per second, but only
; once per request. "0" means always validate)
; Enables or disables file search in include_path optimization
; If disabled, all PHPDoc comments are dropped from the code to reduce the
; size of the optimized code.
; If disabled, PHPDoc comments are not loaded from SHM, so "Doc Comments"
; may be always stored (save_comments=1), but not loaded by applications
; that don't need them anyway.
; If enabled, a fast shutdown sequence is used for the accelerated code
; Allow file existence override (file_exists, etc.) performance feature.
; A bitmask, where each bit enables or disables the appropriate OPcache
; The location of the OPcache blacklist file (wildcards allowed).
; Each OPcache blacklist file is a text file that holds the names of files
; that should not be accelerated. The file format is to add each filename
; to a new line. The filename may be a full path or just a file prefix
; (i.e., /var/www/x blacklists all the files and directories in /var/www
; that start with 'x'). Line starting with a ; are ignored (comments).
; Allows exclusion of large files from being cached. By default all files
; are cached.
; Check the cache checksum each N requests.
; The default value of "0" means that the checks are disabled.
; How long to wait (in seconds) for a scheduled restart to begin if the cache
; is not being accessed.
; OPcache error_log file name. Empty string assumes "stderr".
; All OPcache errors go to the Web server log.
; By default, only fatal errors (level 0) or errors (level 1) are logged.
; You can also enable warnings (level 2), info messages (level 3) or
; debug messages (level 4).
; Preferred Shared Memory back-end. Leave empty and let the system decide.
; Protect the shared memory from unexpected writing during script execution.
; Useful for internal debugging only.
Then I restarted Apache. Seems working fine.
Drupal 8's installation doesn't give me any warning.
@fabrizior You saved my day! Did use full path in the zend_extension section though. Didn't want to take chances since all zend_extension definitions I saw in php.ini used full path.
I am installing Drupal at very first time.
And have same error.
And i apply this first solution.
And works fine for me...“Every solution to every problem is simple. It's the distance between the two where the mystery lies.”
Correct information I save my time a lot!
For Mac OS X simply uncomment this row in php.ini (located in /Applications/XAMPP/xamppfiles/etc/):zend_extension=opcache.so
And restart Apache.
php.net | docs for opcache
// Add below line at php.ini file. This alone will fix this issue.
zend_extension = "C:\xampp\php\ext\php_opcache.dll"
If your XAMPP comes with PHP 5.5+ by default, opcache already included in the bundle, you will just need to enable it. To enable the extension:
Be sure to add this zend_extension URL reference to the PHP.ini options [PHP] section. I added it at end of "Paths and Directories", just before "File Uploads" settings.
And in ampps ? how i enable it ?
How to fix maximum upload files?
you can refer https://www.drupal.org/docs/7/managing-site-performance/increase-upload-... to fix upload size in your php.ini
Works for me! Thank you.
Thank you. I am going learn Drupal development so i am searching for more information to save time and knowledge.
1) Add this line zend_extension = "C:\xampp\php\ext\php_opcache.dll".
2) Remove ";" from stating of following linesopcache.enable=1 (Determines if Zend OPCache is enabled for the CLI version of PHP)
opcache.memory_consumption=64 (The OPcache shared memory storage size)
opcache.max_wasted_percentage=5 (The maximum percentage of "wasted" memory until a restart is scheduled)
opcache.use_cwd=1 (When this directive is enabled, the OPcache appends the current working directory to the script key, thus eliminating possible collisions between files with the same name (basename))
opcache.max_wasted_percentage=5(The maximum percentage of "wasted" memory until a restart is scheduled.)
Worked perfectly on D8.
