從靜態及動態測試中可以看出靜態頁面的響應速度明顯比動態資源快！
xchahe
[root@husa php]# yum install php-xcache
xcache位於epel源
php-xcache x86_64 3.1.1-1.el7 epel 72 k
查看xcache生成的各種文件
[root@husa php]# rpm -ql php-xcache
/etc/php.d/xcache.ini
/usr/lib64/php/modules/xcache.so
/usr/share/doc/php-xcache-3.1.1

/usr/share/doc/php-xcache-3.1.1/THANKSxcache配置文件
/etc/php.d/xcache.ini
[xcache.admin]
xcache.admin.enable_auth = On #表示是否啓用xcache
xcache.admin.user = "mOo" #表示xcache的admin的用戶名
xcache.admin.pass = "md5 encrypted password" #表示xcache的admin的用戶密碼
xcache.size = 60M #表示xcache的緩存大小
xcache.ttl = 0 #表示xcache的緩存生命時長，0表示forever配置xcache生效
直接reload php-fpm
[root@husa php.d]# systemctl reload php-fpm配置xcache之後的動態資源請求結果

編譯安裝xcache
編譯安裝php擴展
1、安裝php-devel
[root@husa php.d]# systemctl reload php-fpm2、下載xcache
[root@husa ~]# ls
99.sh anaconda-ks.cfg a.sh grub.bak linux-3.10.67.tar.xz pma scp.txt service.sh show.sh xcache-3.2.0.tar.bz2
[root@husa ~]# tar xjf xcache-3.2.0.tar.bz2
[root@husa ~]# ls
99.sh a.sh linux-3.10.67.tar.xz scp.txt show.sh xcache-3.2.0.tar.bz2
anaconda-ks.cfg grub.bak pma service.sh xcache-3.2.03、在源代碼目錄中運行phpize命令
phpize - prepare a PHP extension for compiling
這個命令是用來爲PHP編譯安裝擴展的
4、配置編譯腳本然後編譯安裝
/configure --enable-xcache --with-php-config=/usr/bin/php-config
[root@husa xcache-3.2.0]# make -j 2 && make install–enable-xcache表示編譯安裝之後直接啓用xcache，with-php-config表示提供php的配置文件給php-xcache
5、把源代碼目錄中的xcache.ini配置文件放置到/etc/php.d目錄中然後進行相應的配置
[root@husa xcache-3.2.0]# cp xcache.ini /etc/php.d/ 6、重載php-fpm
[root@husa php.d]# systemctl reload php-fpm7、壓力測試
注意：本地測試沒有考慮帶寬，因此要遠程測試
