nginx环境下 XCache安装配置
XCache安装配置一、下载
下载地址：http://xcache.lighttpd.net/wiki/Release-1.2.2
二、安装模块
tar zxvfxcache-1.2.2.tar.gz
cd xcache-1.2.2
/usr/local/php/bin/phpize
./configure –with-php-config=/usr/local/php/bin/php-config –enable-xcache –enable-xcache-optimizer
make
make install
三、算出密码的MD5字串（管理时会用到）
echo -n “123456″ | md5sum
四、配置XCache
vi /usr/local/php/etc/php.ini
在末尾添加
zend_extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/xcache.so
;zend_extension = xcache.so
; Change xcache.admin.user to your preferred login name
xcache.admin.user = “xcache”
; Change xcache.admin.pass to the MD5 fingerprint of your password
; Use md5 -s “your_secret_password” to find the fingerprint
xcache.admin.pass = “e10adc3949ba59abbe56e057f20f883e”
; Change xcache.size to tune the size of the opcode cache
xcache.size = 256M
xcache.shm_scheme = “mmap”
; cpu number (cat /proc/cpuinfo |grep -c processor)
xcache.count = 8
xcache.slots = 8K
xcache.ttl = 0
xcache.gc_interval = 0
; Change xcache.var_size to adjust the size of variable cache
xcache.var_size = 8M
; cpu number (cat /proc/cpuinfo |grep -c processor)
xcache.var_count = 8
xcache.var_slots = 8K
xcache.var_ttl = 0
xcache.var_maxttl = 0
xcache.var_gc_interval = 300
xcache.test = Off
xcache.readonly_protection = On
xcache.mmap_path = “/dev/zero”
xcache.coredump_directory = “”
xcache.cacher = On
xcache.stat = On
xcache.optimizer = Off
xcache.coverager = On
xcache.coveragedump_directory = “”
注意点：
zend_extension = 全路径（推荐）或者 extension= cache
重启nginx
正常load之后,
在phpinfo显出的信息内
Zend这快应该会加上XCache的内容
This program makes use of the Zend Scripting Language Engine:
Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies
with XCache v1.2.2, Copyright (c) 2005-2007, by mOo
with Zend Extension Manager v1.2.2, Copyright (c) 2003-2007, by Zend Technologies
with Zend Optimizer v3.3.3, Copyright (c) 1998-2007, by Zend Technologies大功告成
如果要WEB方式查看xcache状态
把源码下的admin拷贝到任意站点目录，然后访问，输入设定的user password，即可查看
