php-xcache编译安装

[root@localhost local]# tar -xf xcache-3.2.0.tar.bz2 

[root@localhost xcache-3.2.0]# man -M /usr/local/php/php/man phpize 查看帮助文档

[root@localhost xcache-3.2.0]# /usr/local/php/bin/phpize

[root@localhost xcache-3.2.0]# man -M /usr/local/php/php/man php-config查看帮助文档

[root@localhost xcache-3.2.0]# ./configure --enable-xcache    --with-php-config=/usr/local/php/bin/php-config 

[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'

mkdir: created directory `/www/b.net'

[root@localhost local]# mkdir /var/log/httpd/

[root@localhost local]# vim /etc/httpd/extra/httpd-vhosts.conf
