Redis模块的安装，首先wget下载源码包。

因为缺少configure文件，没办法直接./方式编译，所以需要先生成configure文件。
[root@jimmylinux-002 src]# cd phpredis-develop
[root@jimmylinux-002 phpredis-develop]# /usr/local/php7/bin/phpize
Configuring for:
PHP Api Version: 20131106
Zend Module Api No: 20131226
Zend Extension Api No: 220131226
Cannot find autoconf. Please check your autoconf installation and the 这里有报错，提示没有找到autoconf。
$PHP_AUTOCONF environment variable. Then, rerun this script.
[root@jimmylinux-002 phpredis-develop]# yum install -y autoconf yum安装缺少的文件
安装完缺少的文件后再执行 /usr/local/php7/bin/phpize 生成configure
[root@jimmylinux-002 phpredis-develop]# /usr/local/php7/bin/phpize
Configuring for:
PHP Api Version: 20160303
Zend Module Api No: 20160303
Zend Extension Api No: 320160303
使用./进行配置
[root@jimmylinux-002 phpredis-develop]# ./configure --with-php-config=/usr/local/php7/bin/php-config
看到下面的提示说明配置完成
creating libtool
appending configuration tag "CXX" to libtool
configure: creating ./config.status
config.status: creating config.h
[root@jimmylinux-002 phpredis-develop]# echo $? 也可以使用echo命令检查，如果是0说明没有问题。
0
make命令开始编译
[root@jimmylinux-002 phpredis-develop]# make
看到下面提示说明编译完成
Build complete.
Don't forget to run 'make test'.
执行命令make install
[root@jimmylinux-002 phpredis-develop]# make install
Installing shared extensions: /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/ 会把redis.so文件放到这个路径下
[root@jimmylinux-002 phpredis-develop]# ls /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/
opcache.so redis.so 这个目录就生成了一个redis.so，这个文件就是我们要的扩展模块。
[root@jimmylinux-002 phpredis-develop]# /usr/local/php7/bin/php -m 查看php支持的模块

[Zend Modules] 现在php还不支持redis这个模块
[root@jimmylinux-002 phpredis-develop]# /usr/local/php7/bin/php -m |grep redis 这里也是没有加载出redis模块的
[root@jimmylinux-002 phpredis-develop]#
需要编辑配置文件，让php支持redis这个模块。首先查看扩展模块存放目录，我们可以在php.ini中去自定义该路径
[root@jimmylinux-002 phpredis-develop]# /usr/local/php7/bin/php -i |grep extension_dir
extension_dir => /usr/local/php7/lib/php/extensions/no-debug-zts-20160303 => /usr/local/php7/lib/php/extensions/no-debug-zts-20160303
sqlite3.extension_dir => no value => no value 其实这个路径就是刚才生成redis模块的路径，一般保持默认路径不需要修改。
[root@jimmylinux-002 phpredis-develop]# ls /usr/local/php7/lib/php/extensions/no-debug-zts-20160303
opcache.so redis.so
编辑php.ini文件，增加一行配置，放到extension文件最后一行。
[root@jimmylinux-002 phpredis-develop]# vim /usr/local/php7/etc/php.ini
在extension中添加一行 extension=redis.so
;extension=php_pdo_firebird.dll
;extension=php_pdo_mysql.dll
;extension=php_pdo_oci.dll
;extension=php_pdo_odbc.dll
;extension=php_pdo_pgsql.dll
;extension=php_pdo_sqlite.dll
;extension=php_pgsql.dll
;extension=php_shmop.dll
extension=redis.so
这个时候再去查看就有加载redis模块了
总结：
扩展模块安装首先需要下载源码包，redis模块属于第三方提供，在PHP源码包里面本身是没有的，实际上PHP源码包的ext目录，里面有很多的模块，如果编译的模块已经在自带的源码包ext目录存在，那么可以直接进入到需要安装模块的目录，然后使用命令 /usr/local/php7/bin/phpize 编译，不需要再去下载了。
例如安装zip模块
进入到ext目录可以看到很多PHP源码包自带的扩展模块
按照如下步骤操作：
[root@jimmylinux-002 zip]# cd zip
[root@jimmylinux-002 zip]# /usr/local/php7/bin/phpize
[root@jimmylinux-002 zip]# ./configure --with-php-config=/usr/local/php7/bin/php-config
[root@jimmylinux-002 zip]# make
[root@jimmylinux-002 zip]# make install
[root@jimmylinux-002 zip]# ls /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/
opcache.so redis.so zip.so 这里就多了一个zip.so 模块
最后一步在php.ini配置文件添加extension=zip.so
[root@jimmylinux-002 zip]# vim /usr/local/php7/etc/php.ini
;extension=php_pdo_mysql.dll
;extension=php_pdo_oci.dll
;extension=php_pdo_odbc.dll
;extension=php_pdo_pgsql.dll
;extension=php_pdo_sqlite.dll
;extension=php_pgsql.dll
;extension=php_shmop.dll
extension=redis.so
extension=zip.so 配置文件中添加extension=zip.so
已经有zip说明安装成功
