Linux下安装php的扩展文件fileinfo.so文件

1.首先检查系统是否已经安装

1. [root@iZbp1dwql3ymcem09rfdchZ ~]# php -i|grep fileinfo  
2. Configure Command =>  "./configure"  "--prefix=/alidata/server/php" "--enable-opcache" "--with-config-file-path=/alidata/server/php/etc" "--with-mysql=mysqlnd" "--with-mysqli=mysqlnd" "--with-pdo-mysql=mysqlnd" "--enable-fpm" "--enable-fastcgi" "--enable-static" "--enable-inline-optimization" "--enable-sockets" "--enable-wddx" "--enable-zip" "--enable-calendar" "--enable-bcmath" "--enable-soap" "--with-zlib" "--with-iconv" "--with-gd" "--with-xmlrpc" "--enable-mbstring" "--without-sqlite" "--with-curl" "--enable-ftp" "--with-mcrypt" "--with-freetype-dir=/usr/local/freetype.2.1.10" "--with-jpeg-dir=/usr/local/jpeg.6" "--with-png-dir=/usr/local/libpng.1.2.50" "--disable-ipv6" "--disable-debug" "--with-openssl" "--disable-maintainer-zts" "--disable-safe-mode" "--disable-fileinfo"  
3. fileinfo  
4. fileinfo support => enabled  

如果出现上面说明已经安装

2.执行下载包含fileinfo扩展的php安装包命令，也可以独立下载fileinfo编译安装包

wget -O php-5.6.9.tar.gz http://cn2.php.net/get/php-5.6.9.tar.gz/from/this/mirror

3.解压

tar -zxvf php-5.6.9.tar.gz

4.当前目录解压完，进入下面目录 

cd php-5.6.9/ext/fileinfo/

5.在之前已经编译安装的的php的bin目录中找到命令phpize执行生成.configure文件

本人已安装php的目录命令：/alidata/server/php-5.5.7/bin/phpize

6.配置、编译安装

 ./configure -with-php-config=/alidata/server/php-5.5.7/bin/php-config

make && make install

7.修改php.ini
加入:extension=fileinfo.so

8.重启服务器
