XCache 是一个又快又稳定的 PHP opcoolcode 缓存器. 经过良好的测试并在大流量/高负载的生产机器上稳定运行. 经过(在linux 上)测试并支持所有现行 PHP 分支的最新发布版本, 如 PHP_4_3 PHP_4_4 PHP_5_0 PHP_5_1 PHP_5_2 HEAD(6.x), 并支持线程安全/Windows. 与同类 opcoolcode 缓存器相比更胜一筹, 比如能够快速跟进 PHP 版本.下面介绍如何安装配置。
1、安装xcache
wget
http://xcache.lighttpd.net/pub/Releases/1.3.2/xcache-1.3.2.tar.gz
tar -zxvf xcache-1.3.2.tar.gz
cd xcache-1.3.2
phpize
./configure --enable-xcache
make
make install www.2cto.com
2、配置xcache
打开php.ini文件，增加如下代码：
[xcache-common]
; change me - 64 bit php => /usr/lib64/php/modules/xcache.so
; 32 bit php => /usr/lib/php/modules/xcache.so
zend_extension = /usr/lib64/php/modules/xcache.so
[xcache.admin]
xcache.admin.auth = On
xcache.admin.user = "mOo"
; xcache.admin.pass = md5($your_password)
xcache.admin.pass = ""
[xcache]
xcache.shm_scheme = "mmap"
xcache.size = 32M
xcache.count = 1
xcache.slots = 8K
xcache.ttl = 3600
xcache.gc_interval = 300
; Same as aboves but for variable cache
; If you don't know for sure that you need this, you probably don't
xcache.var_size = 0M
xcache.var_count = 1
xcache.var_slots = 8K
xcache.var_ttl = 0
xcache.var_maxttl = 0
xcache.var_gc_interval = 300
; N/A for /dev/zero
xcache.readonly_protection = Off
xcache.mmap_path = "/dev/zero"
xcache.cacher = On
xcache.stat = On
注意修改zend_extension = /usr/lib64/php/modules/xcache.so为正确的路径。
