【redis学习二】多php版本下phpredis扩展安装

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 ofarginfo_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 functioncreate_cluster_context’:

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');
