背景：安装完redis之后，需要安装phpredis扩展，才能让php操作redis；本机有多个php版本，安装过程中遇到的坑分享一下。
一 下载
git上下载redis的扩展包
git clone https://github.com/nicolasff/phpredis
二 挂载和configure
在shell中输入 phpize 【注意：多个php版本的时候需要指定】
./configure 【phpize是用来扩展php扩展模块的，通过phpize可以建立php的外挂模块】
注意：（phpize 如果包含多个php，必须指定位置）
cuihuan:phpredis cuixiaohuan$ ../php/bin/phpize
Configuring for:
PHP Api Version: 20121113
Zend Module Api No: 20121212
Zend Extension Api No: 220121212
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
报错的话需要安装：brew install autoconf [phpize 报错] 否则没有phpize
[work@cuixiaozhuai phpredis]$ ../php/bin/phpize
Configuring for:
PHP Api Version: 20041225
Zend Module Api No: 20060613
Zend Extension Api No: 220060519
[work@cuixiaozhuai phpredis]$ ./configure --with-php-config=/home/work/thirdparty/php5/bin/php-config
当存在多个版本的php的时候，需要指定配置文件
./configure --with-php-config=/home/work/thirdparty/php5/bin/php-config
三 编译和安装
make 之后最好make test
make install
cuihuan:phpredis cuixiaohuan$ make
。。。
Build complete.
Don't forget to run 'make test'.
cuihuan:phpredis cuixiaohuan$ make test
cuihuan:phpredis cuixiaohuan$ make install
四 问题修复
【已修复，但是原因可能不太准确】
make编译报错
.libs/redis_cluster.o(.data.rel.local+0x0): In function `ht_free_seed':
/home/work/thirdparty/php5/php5/phpredis/redis_cluster.c:226: multiple definition of `arginfo_scan'
.libs/redis.o(.data.rel.local+0xe0):/home/work/thirdparty/php5/php5/p hpredis/redis.c:452: first defined here
/usr/bin/ld: Warning: size of symbol `arginfo_scan' changed from 160 in .libs/redis.o to 200 in .libs/redis_cluster.o

collect2: ld returned 1 exit status
make: *** [redis.la] Error 1
最初以为是php多个版本生成install问题，采用./configure 指定php版本，指定php位置。
但是效果还是有问题。
最终通过修改redis_cluester.c 中，注释掉了这两个重复的
40
41 /* Argument info for HSCAN, SSCAN, HSCAN */
42 /*ZEND_BEGIN_ARG_INFO_EX(arginfo_kscan, 0, 0, 2)
43 ZEND_ARG_INFO(0, str_key)
44 ZEND_ARG_INFO(1, i_iterator)
45 ZEND_ARG_INFO(0, str_pattern)
46 ZEND_ARG_INFO(0, i_count)
47 ZEND_END_ARG_INFO();
48 */
49
50 /* Argument infor for SCAN */
51 /*
52 ZEND_BEGIN_ARG_INFO_EX(arginfo_scan, 0, 0, 2)
53 ZEND_ARG_INFO(1, i_iterator)
54 ZEND_ARG_INFO(0, str_node)
55 ZEND_ARG_INFO(0, str_pattern)
56 ZEND_ARG_INFO(0, i_count)
57 ZEND_END_ARG_INFO();
58 */
五 简单测试
<?php
$redis = new Redis();
$conn = $redis->connect('127.0.0.1',6379);
echo "redis pass and status show</br>";
var_dump($redis->ping());
$redis->set('test_key','test_value');
echo "test set val=".$redis->get('test_key')."</br>";
$redis->setnx('unique_key',"unique_val");
$redis->setnx('unique_key',"unique_val_2");
echo $redis->get("unique_key");
sleep(60);
echo 'is exist'.$redis->exists('test_60s');
echo 'not has value'.$redis->get('test_60s');
$redis->delete('test_key','test_60s');
