如何在Ubuntu 14上安装PHP 5.6 redis扩展

我们曾经使用PECL来安装PHP的Redis扩展。 但似乎PECL已经放弃了对PHP版本低于7.0的支持。 没有PECL的最好的方法是什么？ 我们在运行PHP 5.6的Ubuntu 14.x上

ubuntu@box776:~$ pecl help version PEAR Version: 1.10.1 PHP Version: 5.6.18 Zend Engine Version: 2.6.0 Running on: Linux box776.localdomain 3.13.0-86-generic #131-Ubuntu SMP Thu May 12 23:33:13 UTC 2016 x86_64

这一切似乎都顺风顺水，但composer install说：

 $ composer install --no-interaction You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug Loading composer repositories with package information Installing dependencies (including require-dev) from lock file Your requirements could not be resolved to an installable set of packages. Problem 1 - The requested PHP extension ext-redis * is missing from your system. Install or enable PHP's redis extension. composer install --no-interaction returned exit code 2 Action failed: composer install 

更新2

• 正确获取我的服务器维护脚本
• 内核恐慌 – 不同步：试图杀死初始化（使用qemu为Rasbian ARM图像）
• 了解Docker中的Java内存行为
• 使用haproxy的ftp反向代理
• 1866 MHz RAM意外运行在1333 MHz

我SSH进入箱子，并运行相同的命令…

 ubuntu@box776:~$ apt-get install php5-redis E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root? ubuntu@box776:~$ sudo apt-get install php5-redis Reading package lists...

我不知道最后两行是我失踪了吗？ 它是否告诉我，我需要采取额外的步骤来“启用模块redis”？
