xchahe

[root@husa php]# yum install php-xcache
xcache位于epel源
php-xcache                    x86_64                    3.1.1-1.el7
c5fc
epel                     72 k

查看xcache生成的各种文件

[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/THANKS

xcache配置文件

/etc/php.d/xcache.ini

[xcache.admin]
xcache.admin.enable_auth = On       #表示是否启用xcache
xcache.admin.user = "mOo"           #表示xcache的admin的用户名
xcache.admin.pass = "md5 encrypted password"    #表示xcache的admin的用户密码
xcache.size  =               60M    #表示xcache的缓存大小
xcache.ttl   =                 0    #表示xcache的缓存生命时长，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之后的动态资源请求结果

编译安装xcache

编译安装php扩展

1、安装php-devel

[root@husa php.d]# systemctl reload php-fpm

2、下载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-3.2.0

3、在源代码目录中运行phpize命令

phpize - prepare a PHP extension for compiling
这个命令是用来为PHP编译安装扩展的

4、配置编译脚本然后编译安装

/configure --enable-xcache --with-php-config=/usr/bin/php-config
[root@husa xcache-3.2.0]# make -j 2 && make install

–enable-xcache表示编译安装之后直接启用xcache，with-php-config表示提供php的配置文件给php-xcache

5、把源代码目录中的xcache.ini配置文件放置到/etc/php.d目录中然后进行相应的配置

[root@husa xcache-3.2.0]# cp xcache.ini /etc/php.d/

6、重载php-fpm

[root@husa php.d]# systemctl reload php-fpm

7、压力测试

注意：本地测试没有考虑带宽，因此要远程测试
