opcache的配置

; Enable Zend OPcache extension module

zend_extension=opcache.so

; Determines if Zend OPCache is enabled

opcache.enable=1

; Determines if Zend OPCache is enabled for the CLI version of PHP

;opcache.enable_cli=0

; The OPcache shared memory storage size.

; 无影响

opcache.memory_consumption=256

; The amount of memory for interned strings in Mbytes.

; 无影响

opcache.interned_strings_buffer=16

; The maximum number of keys (scripts) in the OPcache hash table.

; Only numbers between 200 and 100000 are allowed.

; wuyingxiang

opcache.max_accelerated_files=8000

; The maximum percentage of "wasted" memory until a restart is scheduled.

;opcache.max_wasted_percentage=5

; 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.

;opcache.use_cwd=1

; When disabled, you must reset the OPcache manually or restart the

; webserver for changes to the filesystem to take effect.

;opcache.validate_timestamps=1

; 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)

opcache.revalidate_freq=60

; Enables or disables file search in include_path optimization

;opcache.revalidate_path=0

; If disabled, all PHPDoc comments are dropped from the code to reduce the

; size of the optimized code.

;opcache.save_comments=1

; 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.

;opcache.load_comments=1

; If enabled, a fast shutdown sequence is used for the accelerated code

opcache.fast_shutdown=1

; Allow file existence override (file_exists, etc.) performance feature.

;opcache.enable_file_override=0

; A bitmask, where each bit enables or disables the appropriate OPcache

; passes

;opcache.optimization_level=0xffffffff

;opcache.inherited_hack=1

;opcache.dups_fix=0

; 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.

opcache.blacklist_filename=/etc/php.d/opcache*.blacklist

; Allows exclusion of large files from being cached. By default all files

; are cached.

;opcache.max_file_size=0

; Check the cache checksum each N requests.

; The default value of "0" means that the checks are disabled.

;opcache.consistency_checks=0

; How long to wait (in seconds) for a scheduled restart to begin if the cache

; is not being accessed.

;opcache.force_restart_timeout=180

; OPcache error_log file name. Empty string assumes "stderr".

;opcache.error_log=

; 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).

;opcache.log_verbosity_level=1

; Preferred Shared Memory back-end. Leave empty and let the system decide.

;opcache.preferred_memory_model=

; Protect the shared memory from unexpected writing during script execution.

; Useful for internal debugging only.

;opcache.protect_memory=0

; Validate cached file permissions.

; Leads OPcache to check file readability on each access to cached file.

; This directive should be enabled in shared hosting environment, when few

; users (PHP-FPM pools) reuse the common OPcache shared memory.

;opcache.validate_permission=0

; Prevent name collisions in chroot'ed environment.

; This directive prevents file name collisions in different "chroot"

; environments. It should be enabled for sites that may serve requests in

; different "chroot" environments.

;opcache.validate_root=0
