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/phpizeConfiguring for:PHP Api Version:         20121113Zend Module Api No:      20121212Zend Extension Api No:   220121212Cannot 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:         20041225Zend Module Api No:      20060613Zend 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

cuihuan:phpredis cuixiaohuan$ make。。。Build complete.Don't forget to run 'make test'.cuihuan:phpredis cuixiaohuan$ make testcuihuan:phpredis cuixiaohuan$ make install

四 问题修复

【已修复，但是原因可能不太准确】

.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.libs/redis_cluster.o(.data.rel.local+0xe0): In function `create_cluster_context':/home/work/thirdparty/php5/php5/phpredis/redis_cluster.c:276:     multiple definition of `arginfo_kscan'.libs/redis.o(.data.rel.local+0x0):/home/work/thirdparty/php5/php5/phpredis/redis.c:364: first defined herecollect2: ld returned 1 exit statusmake: *** [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。

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

    connect('127.0.0.1',6379);    echo "redis pass and status show
";    var_dump($redis->ping());    $redis->set('test_key','test_value');    echo "test set val=".$redis->get('test_key')."
";    $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');
