我的 XCache 配置可能有问题。服务器在 CentOS 7.2 和 Plesk 12.5 上运行

php -v给出以下输出：

PHP 5.4.16 (cli) (built: Aug 11 2016 21:24:59)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies
    with XCache v3.2.0, Copyright (c) 2005-2014, by mOo
    with the ionCube PHP Loader (enabled) + Intrusion Protection from ioncube24.com (unconfigured) v5.0.12, Copyright (c) 2002-2015, by ionCube Ltd.
    with XCache Cacher v3.2.0, Copyright (c) 2005-2014, by mOo

我正在尝试运行以下脚本来测试 XCache，它只显示Clearing XCache...并且控制台指示 500（内部服务器错误）

<?php
error_reporting(E_ALL & ~E_NOTICE);

echo '<pre>';
echo 'Clearing XCache...';

for ($x = 0, $total = xcache_count(XC_TYPE_VAR); $x < $total; $x++)
{
    xcache_clear_cache(XC_TYPE_VAR, $x);
    echo "\n.";
}

echo "\nCompleted</pre>";

下面是我当前的 XCache 配置/etc/php.d/axcache.ini 

[xcache-common]
;; non-Windows example:
extension = "./usr/lib64/php/modules/xcache.so"
;; Windows example:
; extension = php_xcache.dll

[xcache.admin]
xcache.admin.enable_auth = "Off"

; use http://xcache.lighttpd.net/demo/cacher/mkpassword.php to generate your encrypted password
xcache.admin.user = "admin"
xcache.admin.pass = "md5$password_removed"

[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 =                 2
; 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 =             2
xcache.var_slots =            8K
; default value for $ttl parameter of xcache_*() functions
xcache.var_ttl   =             7200
; hard limit ttl that cannot be exceed by xcache_*() functions. 0=unlimited
xcache.var_maxttl   =          14400
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 =            On

[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 = "/tmp/pcov/"

可能是什么问题？

服务器上似乎有多个xcache.ini文件：

# find -name *xcache.ini
./opt/plesk/php/5.3/etc/php.d/40-xcache.ini
./opt/plesk/php/5.2/etc/php.d/40-xcache.ini
./opt/plesk/php/5.4/etc/php.d/40-xcache.ini
./etc/php.d/axcache.ini
./usr/local/src/xcache-3.2.0/xcache.ini

我在它们中都做了类似的配置。似乎还有多个xcache.so文件。这条线到底应该extension =指向哪里？

# find -name xcache.so
./opt/plesk/php/5.3/lib64/php/modules/xcache.so
./opt/plesk/php/5.2/lib64/php/modules/xcache.so
./opt/plesk/php/5.4/lib64/php/modules/xcache.so
./usr/lib64/php/modules/xcache.so
./usr/local/src/xcache-3.2.0/.libs/xcache.so
./usr/local/src/xcache-3.2.0/modules/xcache.so

如何检查我的 wordpress 站点是否使用 Xcache 来缓存其内容？如何验证？无法使用 xcache 管理员，因为我还有一个使用 ipboard 的论坛。那个论坛用xcache。所以，xcache 管理员总是显示一些用法。
