PHP扩展模块安装
编译httpd时，有涉及动态和静态模块，PHP也一样有静态与动态之分，之前所涉及到的PHP安装都全部为静态，并没有任何动态的模块，所谓动态，就是一个独立存在的.so文件，在httpd中PHP就是以动态模块的形式被加载的。PHP一旦编译完成后，要想再增加一个功能的话，要么重新编译PHP，要么直接编译一个扩展模块（生成一个.so文件），然后在php.ini中配置一下，就可以被加载使用了。
1.查看PHP加载了哪些模块 [root@linuxmi ~]# /usr/local/php/bin/php -m [PHP Modules] bz2 Core ctype date dom ereg exif fileinfo filter gd hash iconv json libxml mbstring mcrypt mysql mysqli openssl pcre PDO pdo_mysql pdo_sqlite Phar posix Reflection session SimpleXML soap sockets SPL sqlite3 standard tokenizer xml xmlreader xmlwriter zlib [Zend Modules] 2.安装一个PHP的redis扩展模块。 [root@linuxmi ~]# cd /usr/local/src/ [root@linuxmi src]# wget https://codeload.github.com/phpredis/phpredis/zip/develop [root@linuxmi src]# mv develop phpredis-develop.zip [root@linuxmi src]# unzip phpredis-develop.zip //yum install -y unzip [root@linuxmi src]# cd phpredis-develop [root@linuxmi phpredis-develop]# [root@linuxmi src]# cd phpredis-develop [root@linuxmi phpredis-develop]# /usr/local/php7/bin/phpize //生成configure文件 Configuring for: PHP Api Version: 20160303 Zend Module Api No: 20160303 Zend Extension Api No: 320160303 Cannot find autoconf.

You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in Unknown on line 0 extension_dir => /usr/local/php/lib/php/extensions/no-debug-zts-20131226 => /usr/local/php/lib/php/extensions/no-debug-zts-20131226 sqlite3.extension_dir => no value => no value [root@linuxmi phpredis-develop]# vim /usr/local/php7/etc/php.ini //增加一行配置（可以放到文件最后一行） 定义如下： extension = redis.so [root@linuxmi phpredis-develop]# /usr/local/php7/bin/php -m |grep redis redis 增加示例图：
缺少autoconf包，安装yum install -y autoconf
这个不影响使用，如果要去掉它，可以在php.ini里设置一下timezone那个参数
