##PHP5.3.27编译参数详解
[root@lnmp01 tools]# tar xf php-5.3.27.tar.gz解压压缩包
[root@lnmp01 tools]# cd php-5.3.27 进入php安装目录
./configure 编译参数
--prefix=/application/php5.3.27 指定php的安装路径为/application/php5.3.27
--with-mysql=/application/mysql/ 需要指定mysql的安装路径,安装PHP需要的MySQL相关内容。当然如果没有MySQL软件包，也可以不单独安装，这样的情况可使用--with-mysql=mysqlnd替代--with-mysql=/application/mysql,因为PHP软件里面已经自带连接MySQL的客户端工具。
--with-iconv-dir=/usr/local/libiconv libiconv库,各种字符集间的转换
--with-freetype-dir 打开对freetype字体库支持
--with-jpeg-dir 打开对jpeg图片的支持

--with-libxml-dir=/usr 打开libxml2库的支持
--enable-xml
--disable-rpath 关闭额外的运行库文件
--enable-safe-mode 打开安全模式
--enable-bcmath 打开图片大小调整,用zabbix监控时会用到该模块
--enable-shmop
--enable-sysvsem 使用sysv信号机制,则打开此选项
