[root@localhost xcache-3.2.0]# make
[root@localhost xcache-3.2.0]# make install
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20131226/
[root@localhost xcache-3.2.0]#
[root@localhost php-5.6.24]# mkdir /etc/php.d
[root@localhost xcache-3.2.0]# cp xcache.ini /etc/php.d/ 为xcache拷贝一个配置文件
[root@localhost xcache-3.2.0]# vim /etc/php.d/xcache.ini
[xcache-common] 定义zend扩展
将安装xcache后的Installing shared extensions路径写在 zend_extension里
extension = /usr/local/php/lib/php/extensions/no-debug-zts-20131226/xcache.so
[xcache.admin] 定义xcache的管理
[xcache]
xcache.shm_scheme = "mmap" 实用哪种方式来共享内存 mmap：内存映射
xcache.size = 60M 缓存空间大小
xcache.count = 1 设置CPU个数
xcache.ttl = 0 过期时间
xcache.gc_interval = 0 垃圾回收器多长时间工作一次
xcache.var_size = 4M xcache的变量缓存空间大小
xcache.var_count = 1 缓存多少个
xcache.var_slots = 8K
xcache.cacher = On
xcache.stat = On 缓存功能是否启用
xcache.optimizer = Off xcache自身的优化器是否启动
要让 xcache重新生效，需要重启apache服务
------------------------------------------
解决：php扩展报错：Cannot find config.m4.
cd /usr/local/php-5.3.28/ext/
./ext_skel --extname=sdomain
cd sdomain/
mv config.m4 /usr/local/php/bin/
-------------------------
启动php虚拟主机：
[root@localhost local]# vim /etc/httpd/httpd.conf
#DocumentRoot "/usr/local/apache/htdocs" 禁用
#Virtual hosts
Include /etc/httpd/extra/httpd-vhosts.conf 启用虚拟主机
[root@localhost local]# vim /etc/httpd/extra/httpd-vhosts.conf 配置虚拟主机配置文件
# Required modules: mod_log_config 此提示需要启动mod_log_config
[root@localhost local]# vim /etc/httpd/httpd.conf 默认已经启用
[root@localhost local]# mkdir /www/{a.org,b.net} -pv
mkdir: created directory `/www‘
mkdir: created directory `/www/a.org‘
