安装XCache模块# phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config --enable-xcache --enable-xcache-optimizer
# make
# make install
算出密码的MD5字串
# echo -n “123456″ | md5sum
配置XCache
# vi /etc/php.ini
zend_extension = /usr/local/php/lib/php/extensions/xcache.so
; Change xcache.admin.user to your preferred login name
xcache.admin.user = "admin"
; 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 = 24M
xcache.shm_scheme = "mmap"
xcache.count = 2
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
xcache.var_count = 1
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 = "/tmp/xcache"
xcache.coredump_directory = ""

示例代码：
<?php
define(TMPDIR, '/tmp');
function load_abc_data()
{
if (xcache_isset("abc_data")) {
return xcache_get("abc_data");
}
// it worth a lock here to avoid useless yet harmful concurrent
// load from any slow backend (backend=mysql here).
$fp = fopen(TMPDIR . "/abc_data.lock", "w");
flock($fp, LOCK_EX);
// check AGAIN after we get the lock
if (xcache_isset("abc_data")) {
fclose($fp);
return xcache_get("abc_data");
}
mysql_query .... and get $data
xcache_set("abc_data", $data, 120); // save for 2 minutes
fclose($fp);
return $data;
}
?>
