phpredis 扩展安装

一 下载：git上下载redis的扩展包

git clone https://github.com/nicolasff/phpredis

二 挂载：在shell中输入 phpize 【查看适合的版本信息】

 ./configure 编译

【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$ 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]$ phpize        
Configuring for:
PHP Api Version:         20041225
Zend Module Api No:      20060613
Zend Extension Api No:   220060519
[work@cuixiaozhuai phpredis]$ ./configure

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 安装： make 之后make test 最好 make install

Build complete.
Don't forget to run 'make test'.

cuihuan:phpredis cuixiaohuan$ make test

四 问题报错修复：【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'

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 进行简单的php操作测试

<?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');
