我已经通过apt-get install gearman-job-server 安装了 gearman 我四处寻找解决方案，但没有取得多大成功。

问题

如何正确安装缺少的 php ext gearman？

我已经通过apt-get install gearman-job-server 安装了 gearman 我一直在寻找解决方案，但没有成功。

这是你的问题。您还没有安装 php 扩展 - 您刚刚安装了程序。

如果你使用命令apt-cache search gearman你可以看到所有与关键字“gearman”相关的aptitude包：

php5-gearman - PHP wrapper to libgearman

python-gearman - Python interface to the Gearman system

如果您看一下，您会发现有一个名为 php5-gearman 的 PHP 扩展。这就是您的错误所指的内容：

您的系统中缺少请求的 PHP 扩展 gearman。

所以只需安装 php5-gearman 并重新启动 php/您的网络服务器：

sudo apt-get install php5-gearman
sudo service php5-fpm restart # restart if you use php5-fpm

Answer 2

您需要按如下方式安装 PHP 依赖项：

sudo apt-get install libgearman-dev

查看this article 以了解基于您的 SO 的更多详细信息。

可能你需要在php conf系统上添加库作为例子：

echo 'extension = gearman.so' > /usr/local/etc/php/conf.d/gearman.ini

希望有帮助

对于 Ubuntu 16.04 Xenial，对我有用的解决方案是按照以下步骤操作：

安装额外的编译包

apt-get -y install wget unzip re2c libgearman-dev

从源安装

mkdir -p /tmp/install

cd /tmp/install

wget https://github.com/wcgallego/pecl-gearman/archive/master.zip

unzip master.zip

cd pecl-gearman-master

phpize

./configure

make install

echo "extension=gearman.so" > /etc/php/7.0/mods-available/gearman.ini

phpenmod -v ALL -s ALL gearman

验证模块是否真的安装

php -m | grep gearman

删除安装文件

rm -rf /tmp/install/pecl-gearman-master

rm /tmp/install/master.zip
