Description (last modified by moo)
Hi Moo,
I need your help once again. I noticed apache was starting to crash on a regular basis. I had to implement new features (which should have been done sooner) to correct the problem.
As I'm sure you alraedy know, apache has memory issues running on windows, memory leaks, etc; I was able to correct the issue by setting the ThreadStackSize? to 8388608 and using the MaxRequestsPerChild? directive.
Most importantly, I enabled mod_fastcgi-2.4.6-AP22.dll. mod_fastcgi is working as it should be, and the server is now stable. However, I check the 3.0.3 Cacher and found the following:
Total: Slots: 128.00 K Size: 60.00 M Available: 58.89 M
Specs:
Windows Server 2008 R2 Duel Quad Core Xeons 16Gb Memory Apache 2.2.21 MySQL 5.5.16 PHP Version 5.4.16
Xcache Settings:
;; this is an example, it won't work unless properly configured into php.ini [xcache-common] ;; non-Windows example: ;;extension = xcache.so ;; Windows example: extension = php_xcache.dll [xcache.admin] xcache.admin.enable_auth = Off xcache.admin.user = "xxxxx" ; set xcache.admin.pass = md5($your_password) ; login use $your_password xcache.admin.pass = "xxxxxx" [xcache] ; ini only settings, all the values here is default unless explained ; select low level shm implemenation xcache.shm_scheme = "mmap" ; to disable: xcache.size=0 ; to enable : xcache.size=64M etc (any size > 0) and your system mmap allows xcache.size = 60M ; set to cpu count (cat /proc/cpuinfo |grep -c processor) xcache.count = 16 ; just a hash hints, you can always store count(items) > slots xcache.slots = 8K ; ttl of the cache item, 0=forever xcache.ttl = 0 ; interval of gc scanning expired items, 0=no scan, other values is in seconds xcache.gc_interval = 0 ; same as aboves but for variable cache xcache.var_size = 4M xcache.var_count = 16 xcache.var_slots = 8K ; default value for $ttl parameter of xcache_*() functions xcache.var_ttl = 0 ; hard limit ttl that cannot be exceed by xcache_*() functions. 0=unlimited xcache.var_maxttl = 0 xcache.var_gc_interval = 300 ; mode:0, const string specified by xcache.var_namespace ; mode:1, $_SERVER[xcache.var_namespace] ; mode:2, uid or gid (specified by xcache.var_namespace) xcache.var_namespace_mode = 0 xcache.var_namespace = "" ; N/A for /dev/zero xcache.readonly_protection = Off ; for *nix, xcache.mmap_path is a file path, not directory. (auto create/overwrite) ; Use something like "/tmp/xcache" instead of "/dev/*" if you want to turn on ReadonlyProtection ; different process group of php won't share the same /tmp/xcache ; for win32, xcache.mmap_path=anonymous map name, not file path xcache.mmap_path = "/dev/zero" ; Useful when XCache crash. leave it blank(disabled) or "/tmp/phpcore/" (writable by php) xcache.coredump_directory = "" ; Windows only. leave it as 0 (default) until you're told by XCache dev xcache.coredump_type = 0 ; disable cache after crash xcache.disable_on_crash = Off ; enable experimental documented features for each release if available xcache.experimental = Off ; per request settings. can ini_set, .htaccess etc xcache.cacher = On xcache.stat = On xcache.optimizer = Off [xcache.coverager] ; enabling this feature will impact performance ; enabled only if xcache.coverager == On && xcache.coveragedump_directory == "non-empty-value" ; per request settings. can ini_set, .htaccess etc ; enable coverage data collecting and xcache_coverager_start/stop/get/clean() functions xcache.coverager = Off xcache.coverager_autostart = On ; set in php ini file only ; make sure it's readable (open_basedir is checked) by coverage viewer script xcache.coveragedump_directory = ""
mod_fastcgi settings:
# Load mod_fcgid LoadModule fastcgi_module modules/mod_fastcgi.dll <IfModule fcgid_module> AddHandler fcgid-script .fcgi .php # Where to look for the php.ini file? FcgidInitialEnv PHPRC "c:/xampp/php" # Set PHP_FCGI_MAX_REQUESTS to greater than or equal to FcgidMaxRequestsPerProcess # to prevent php-cgi process from exiting before all requests completed FcgidInitialEnv PHP_FCGI_MAX_REQUESTS 1000 # Maximum requests a process should handle before it is terminated FcgidMaxRequestsPerProcess 1000 # Number of seconds of idle time before a php-cgi process is terminated FcgidIOTimeout 120 FcgidIdleTimeout 120 FcgidOutputBufferSize 128 FcgidIOTimeout 40 ProcessLifeTime 240 FcgidMaxProcesses 50 #Path to php-cgi FcgidWrapper "c:/xampp/php/php-cgi.exe" .php FcgidInitialEnv PATH "c:/xampp/php;C:\\WINDOWS\\system32;C:\\WINDOWS;C:\\WINDOWS\\System32\\Wbem;" FcgidInitialEnv SystemRoot "C:\\Windows" FcgidInitialEnv SystemDrive "C:" FcgidInitialEnv TEMP "C:\\WINDOWS\\TEMP" FcgidInitialEnv TMP "C:\\WINDOWS\\TEMP" FcgidInitialEnv windir "C:\\WINDOWS" # Max request length #FcgidMaxRequestLen 5242880 FcgidMaxRequestLen 1048576000 </IfModule>
Also tried changing the paths to, same results:
#Path to php-cgi FcgidWrapper "c:/xampp/php/php-cgi.exe" .php FcgidInitialEnv PATH "c:/xampp/php;c:\windows\system32;c:\windows;c:\windows\system32\wbem;" FcgidInitialEnv SystemRoot "c:\windows" FcgidInitialEnv SystemDrive "c:" FcgidInitialEnv TEMP "c:\windows\temp" FcgidInitialEnv TMP "c:\windows\temp" FcgidInitialEnv windir "c:\windows"
I did find this under 3.0.3 - Diagnosis:
SAPI Compatibility Error CGI is not supported Use FastCGI or FPM instead
The Xcache usage seems to be extremely low since enabling mod_fastcgi. Is this normal ? If not, please advise. Thank you.

I'm not windows/apache expert. I never used them for production
Please ask question in xcache @ google groups. Although the problem raised when you use XCache, it's not a XCache problem. Your target is: find a way to run php in FastCGI mode under windows, I'm not even sure if a solution to this is already there
memcache is for caching data, which is good at what it is for. but won't cache opcode of *.php

Update: I switched to memcache and it's working well with fastcgi. I'll use it (memcache ) as an alternative until I hear from you. Thanks.
