如何在linux上安装memcached扩展（将memcached.so扩展添加到php.ini）

我已经将这一行添加到php.ini文件中

extension=memcached.so

当我运行php命令时，我得到了错误消息

[ec2-user@ip-172-31-1-237 ~]$ php -v
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/5.6/modules/memcached.so' - /usr/lib64/php/5.6/modules/memcached.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP 5.6.17 (cli) (built: Jan 16 2016 00:21:00)
Copyright (c) 1997-2015 The PHP Group

我正在AWSEC2（LinuxAMI）上部署php项目。 我已经在LinuxAMI上安装了memcached，并使用此命令成功运行memcached服务

sudo service memcached start 

我已经像这样检查了memcached服务状态

[ec2-user@ip-172-31-1-237 ~]$ echo stats | nc -4 localhost 11211
STAT pid 15597
STAT uptime 5807
...
END

wget http://pecl.php.net/get/memcached
tar -zxvf memcached
cd memcached-x.x.x
phpize

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

然后我试着像这样安装memcached扩展

谁能帮我？

关于。

没有使用apt get安装的选项？@Filp为什么要安装两个不同版本的Memcached软件包？
