【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。

git上下载redis的扩展包

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

在shell中输入 phpize 【注意：多个php版本的时候需要指定】

1. ./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）

1. cuihuan:phpredis cuixiaohuan$ ../php/bin/phpize
2. Configuring for:
3. PHP Api Version: 20121113
4. Zend Module Api No: 20121212
5. Zend Extension Api No: 220121212
6. Cannot find autoconf. Please check your autoconf installation and the
7. $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

1. [work@cuixiaozhuai phpredis]$ ../php/bin/phpize
2. Configuring for:
3. PHP Api Version: 20041225
4. Zend Module Api No: 20060613
5. Zend Extension Api No: 220060519
6. [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

1. ./configure --with-php-config=/home/work/thirdparty/php5/bin/php-config

make 之后最好make test
make install

1. cuihuan:phpredis cuixiaohuan$ make
2. 。。。
3. Build complete.
4. Don't forget to run 'make test'.
6. cuihuan:phpredis cuixiaohuan$ make test
7. cuihuan:phpredis cuixiaohuan$ make install

【已修复，但是原因可能不太准确】
make编译报错

1. .libs/redis_cluster.o(.data.rel.local+0x0): In function `ht_free_seed':
2. /home/work/thirdparty/php5/php5/phpredis/redis_cluster.c:226: multiple definition of `arginfo_scan'
3. .libs/redis.o(.data.rel.local+0xe0):/home/work/thirdparty/php5/php5/p hpredis/redis.c:452: first defined here
4. /usr/bin/ld: Warning: size of symbol `arginfo_scan' changed from 160 in .libs/redis.o to 200 in .libs/redis_cluster.o
5. .libs/redis_cluster.o(.data.rel.local+0xe0): In function `create_cluster_context':
6. /home/work/thirdparty/php5/php5/phpredis/redis_cluster.c:276: multiple definition of `arginfo_kscan'
7. .libs/redis.o(.data.rel.local+0x0):/home/work/thirdparty/php5/php5/phpredis/redis.c:364: first defined here
8. collect2: ld returned 1 exit status
9. 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

1. 40
3. 41 /* Argument info for HSCAN, SSCAN, HSCAN */
5. 42 /*ZEND_BEGIN_ARG_INFO_EX(arginfo_kscan, 0, 0, 2)
7. 43 ZEND_ARG_INFO(0, str_key)
9. 44 ZEND_ARG_INFO(1, i_iterator)
11. 45 ZEND_ARG_INFO(0, str_pattern)
13. 46 ZEND_ARG_INFO(0, i_count)
15. 47 ZEND_END_ARG_INFO();
17. 48 */
19. 49
21. 50 /* Argument infor for SCAN */
23. 51 /*
25. 52 ZEND_BEGIN_ARG_INFO_EX(arginfo_scan, 0, 0, 2)
27. 53 ZEND_ARG_INFO(1, i_iterator)
29. 54 ZEND_ARG_INFO(0, str_node)
31. 55 ZEND_ARG_INFO(0, str_pattern)
33. 56 ZEND_ARG_INFO(0, i_count)
35. 57 ZEND_END_ARG_INFO();
37. 58 */

1. $redis = new Redis();
2. $conn = $redis->connect('127.0.0.1',6379);
4. echo "redis pass and status show
   ";
5. var_dump($redis->ping());
7. $redis->set('test_key','test_value');
8. echo "test set val=".$redis->get('test_key')."
   ";
10. $redis->setnx('unique_key',"unique_val");
11. $redis->setnx('unique_key',"unique_val_2");
13. echo $redis->get("unique_key");
15. sleep(60);
16. echo 'is exist'.$redis->exists('test_60s');
17. echo 'not has value'.$redis->get('test_60s');
18. $redis->delete('test_key','test_60s');
