我已经通过apt-get install gearman-job-server安装了gearman   我一直在寻找一个没有太大成功的解决方案。

这是你的问题。您尚未安装 php 扩展程序 - 您刚刚安装了该程序。

如果您使用命令apt-cache search gearman，您可以在aptitude中查看与关键字“gearman”相关的所有包：

aj@dev ~ $ apt-cache search gearman

php5-gearman - PHP wrapper to libgearman
^^^^^^^^^^^^

python-gear - Pure Python Async Gear Protocol Library
python-gearman - Python interface to the Gearman system
python-gearman.libgearman - Python wrapper of libgearman
python3-gearman.libgearman - Python 3 wrapper of libgearman

如果你看，你可以看到有一个名为php5-gearman的PHP 扩展名。这就是你的错误所指的：

  

系统中缺少所请求的 PHP扩展装备。

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

您需要安装PHP依赖项，如下所示：

sudo apt-get install libgearman-dev

根据您的搜索结果查看this article以获取更多详细信息。

可能你需要在php conf系统上添加库，例如：

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

希望这个帮助

对于Ubuntu 16.04 Xenial，适用于我的解决方案遵循以下步骤：

安装其他软件包进行编译

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

验证模块是否确实安装

php -m | grep gearman

删除安装文件

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

rm /tmp/install/master.zip
