gearman

We use PHP gearman workers to run various tasks in parallel. Everything works just fine, and I have silly little shell script to spin them up when I want them. Being a programmer (and therefore lazy), I wanted to see if I could spin these up via an upstart script. I figured out how to use the instance stanza, so I could start them with an instance number: description "Async insert workers" author "Mike Grunder" env SCRIPT_PATH="/path/to/my/script" instance $N script php $SCRIPT_PATH/worker.php end script And this works great, to start them like so: sudo start async-worker N=1 sudo start async

在 pecl 中的扩展 gearman 已经很久没有更新，最新是 2013 年发布的 gearman-1.1.2.tgz，该版本只支持 PHP7 以下的版本。如果想 在 PHP7.0+ 的环境中安装 Gearman 扩展，需要通过源码编译的方式安装。 说明 ：Gearman 依赖 Gearmand 服务，Gearmand 又依赖 libuuid 包。 完整的 Dockerfile 示例如下： FROM php:7.0-apache # 修改软件更新源 COPY ./source.list /etc/apt/sources.list RUN apt-get update \ # 安装扩展依赖包 && apt-get install -y wget \ # 下载源码包：gearman && mkdir -p /tmp/gearmand /tmp/gearman /tmp/libuuid \ && wget -c https://github.com/gearman/gearmand/releases/download/1.1.18/gearmand-1.1.18.tar.gz \ && tar -xf gearmand-1.1.18.tar.gz -C /tmp/gearmand --strip-components=1 \ && wget -c https://github.com

My dev server is Debian Squeeze and I'm running Gearman 1.1.5 which I compiled from source along with the php pecl extension v1.1.1 If I run the reverse_client.php script I get the GEARMAN_COULD_NOT_CONNECT error. PHP Warning: GearmanClient::do(): send_packet(GEARMAN_COULD_NOT_CONNECT) Failed to send server-options packet -> libgearman/connection.cc:430 in /home/bealers/build/gearman-1.1.1/examples/reverse_client.php on line 26 There are a few similar posts on here about this and they all point to GM not running. It is definitely running. I'm starting it with these params: PARAMS="--queue-type

From what I can see Gearman does not support scheduled jobs or delayed jobs. I was thinking that perhaps the scheduled job could be queued in at first and then added to the Gearman queue after the at time period has expired. at tasks are persistent as they are written as files to a directory in the spool directory of the server. So the only bottle neck would potentially be a simple script to add the task to the Gearman queue because at can't be distributed across servers. Passing it to Gearman to process the actual job means I can get proper job logging etc. Is this the best way to approach

Consider a PHP web application whose purpose is to accept user requests to start generic asynchronous jobs, and then create a worker process/thread to run the job. The jobs are not particularly CPU or memory intensive, but are expected to block on I/O calls fairly often. No more than one or two jobs should be started per second, but due to the long run times there may be many jobs running at once. Therefore, it's of utmost importance that the jobs run in parallel. Also, each job must be monitored by a manager daemon responsible for killing hung workers, aborting workers on user request, etc.

I want to be able to query a gearman server to determine how many instances of a worker I have running (basically I want to make sure that RunTaskA is available and RunTaskB is available if there are no workers handling those tasks, I want to be able to send an alert out. Is there any way to do this? Also: Mad props if you know of a PHP way to query the gearman server. Edit : I know about the PHP gearman extension that is available natively, but I am not looking for a task submission extension, I need something that allows me to query the gearman server and see how many workers are serving a
