# cd /usr/local

# wget http://pecl.php.net/get/redis-4.0.1.tgz

# tar -zxvf redis-4.0.1.tgz

# cd redis-4.0.1

# /opt/lampp/bin/phpize-5.6.38

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
$PHP_AUTOCONF environment variable. Then, rerun this script.
這裡會提示沒有autoconf，那麼安裝它

# cd /usr/local

# wget http://mirrors.kernel.org/gnu/autoconf/autoconf-2.65.tar.gz

# tar -xzvf autoconf-2.65.tar.gz

# cd autoconf-2.65
# ./configure && make && make install

安裝完成繼續配置Redis擴充套件

# cd ..

# cd redis-4.0.1

# /opt/lampp/bin/phpize-5.6.38
# ./configure --with-php-config=/opt/lampp/bin/php-config-5.6.38
# make && make install

安裝後會提示擴充套件位置

Installing shared extensions:     /opt/lampp/lib/php/extensions/no-debug-non-zts-20131226/

進入檢視一下是否存在redis.so

然後再配置php.ini，位置一般在 /opt/lampp/etc/

查詢;extension="interbase.so"，在其下面一行加上

extension="redis.so"

配置成功，重啟Apache，至此PHP可以操作Redis了
