![如何在 Ubuntu 14 上安装 PHP 5.6 redis 扩展](https://linux22.com/image/684901/%E5%A6%82%E4%BD%95%E5%9C%A8%20Ubuntu%2014%20%E4%B8%8A%E5%AE%89%E8%A3%85%20PHP%205.6%20redis%20%E6%89%A9%E5%B1%95.png)
我们曾经使用 PECL 安装 PHP 的 Redis 扩展。但 PECL 似乎已不再支持低于 7.0 的 PHP 版本。没有 PECL 的最佳做法是什么?我们在 Ubuntu 14.x 上运行 PHP 5.6
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

这一切似乎进展顺利,但随后composer install
却说:
$ composer install --no-interaction
You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug

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

我通过 SSH 进入该框并运行了相同的命令......

我想知道最后两行是不是我遗漏了?它是否告诉我需要采取额外步骤来“启用模块 redis”?
答案1
CircleCI 从其自己的位置加载和配置 PHP:。我们通过 APT 安装,然后将 CircleCI 的 PHP 版本连接到 APT 安装的文件,/opt/circleci/php/{version}
解决了发布的问题。它在我们的文件中如下所示:php-redis
circle.yml
dependencies:
pre:
# Set up php-redis.
# The PHPAPI version (20131226) needs to match.
# If we start using a different version of PHP this section may need to be updated.
- sudo apt-add-repository -y ppa:ondrej/php
- sudo apt-get update
- sudo apt-get install php-redis
- echo 'extension=/usr/lib/php/20131226/redis.so' | sudo tee /opt/circleci/php/5.6.17/etc/conf.d/redis.ini
- echo 'extension=/usr/lib/php/20131226/igbinary.so' | sudo tee /opt/circleci/php/5.6.17/etc/conf.d/igbinary.ini
最近,CircleCI 开始使用 运行 Composer 时php -n
,这个问题再次出现,它拒绝加载 PHP 的配置文件,因此忽略了上述更改。但你可以用自己的命令覆盖 Composer 命令。我们将其添加到circle.yml
:
dependencies:
override:
# CircleCI's new method of running composer breaks our php-redis setup below.
- composer install --no-interaction
