1、安装xcache
cd /usr/local/src #进入软件包存放目录
wget http://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz#下载
tar zxvf xcache-3.2.0.tar.gz #解压
cd xcache-3.2.0 #进入安装目录
/usr/bin/phpize#用phpize生成configure配置文件---------这里的目录，用which phpize来找
[root@lgq bin]# ln -sv phpize /usr/src/xcache-3.2.0
‘/usr/src/xcache-3.2.0/phpize’ -> ‘phpize
[root@lgq xcache-3.2.0]# phpize
Configuring for:
PHP Api Version: 20100412
Zend Module Api No: 20100525
Zend Extension Api No: 220100525
[root@lgq xcache-3.2.0]#./configure --enable-xcache--enable-xcache-coverager --enable-xcache-optimizer --with-php-config=/usr/bin/php-config#配置
make #编译
make install #安装
安装完成之后，出现下面的界面，记住以下路径，后面会用到。/usr/lib64/php/modules/
/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/#xcache模块路径
2、创建xcache缓存文件
touch /tmp/xcache #创建文件
chmod 777 /tmp/xcache #设置权限
3、创建xcache管理员密码为123456
echo -n "123456" | md5sum #记住类似下面一行代码（md5加密之后的密码），后面会用到
c1820eeffb72ef4463aa2a67c65c7b0a
4、拷贝xcache后台管理程序到网站根目录
cp -r /usr/local/src/xcache-3.2.0/htdocs /var/www/html/xcache
chownapache.apache-R /var/www/html/xcache#设置xcache目录和网站目录权限相同
5、配置php支持xcache
vi /usr/local/php/etc/php.ini #编辑配置文件，在最后一行添加以下内容
[xcache-common]
extension = xcache.so
[xcache.admin]
xcache.admin.enable_auth = On
xcache.admin.user = "xcache"
xcache.admin.pass = "c1820eeffb72ef4463aa2a67c65c7b0a"
[xcache]
xcache.shm_scheme ="mmap"
xcache.size=60M
xcache.count =1
xcache.slots =8K
xcache.ttl=0
xcache.gc_interval =0
xcache.var_size=64M
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 =""
xcache.cacher =On
xcache.stat=On
xcache.optimizer =Off
[xcache.coverager]
xcache.coverager =On
xcache.coveragedump_directory =""
:wq! #保存退出
6、测试
service php-fpm restart#重启php-fpm
service nginx restart #重启nginx
浏览器打开网站根目录下面的xcache
输入用户名xcache 密码123456
可以看到如下界面
Warning: phpinfo(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /var/www/html/xcache/cacher/index.phpon line 126Warning: phpinfo(): It is not safe to rely on the system's timezone settings.

是因为时区的问题引起的
vim /etc/php.ini 去掉date.timezone前面的;号，后面上 Asia/Shanghai，就不会再提示错误信息了
date.timezone =Asia/Shanghai
