Gearman Server failed over

[sean nguyen]

Hi,

What happens when a gearman server failed? Is there a way to create a
backup server as well?

Thanks,

Sean Nguyen

Hi Sean Nguyen,

For HA purpose, you can use various solution likes Linux HA, heart-beat, wakeamole or similar applications. 

The logic is, one the master server went down, the slave can wake up and take responsibility.

Hi,
supervisord is another popular tool.

The client you are using should be able to add multiple servers for failover.
Your workers would have to register to all the servers also.

Supervisord is a process monitoring/controlling tool, it is used to manage workers, not for the server.

If you are looking for HA, run two servers, and have all clients speak to both of them.

Hello guys,
Would u like to tell me how to specify the worker to run the job? My
environment like this:
Gearmand just as a server, and two workers( one called wrk1 which
running on 192.168.1.11,another called wrk2 running on 192.168.1.12) have
the same function called job. I want to do the job on the 192.168.1.11 at
sometimes or do the job at together.
My source code as bellow:
gearman_client_st *client= gearman_client_create(NULL);
gearman_return_t ret= gearman_client_add_server(client, "localhost",
4730);
void *value= gearman_client_do(client, task_name, "unique_value",
task_para,
strlen(task_para),

&result_size, &rc);

Thanks very much

Hi!

       Would u like to tell me how to specify the worker to run the job? My

environment like this:

You won't be able to specify which worker should run a task in a queue, but you can implement it by registering different function names for each worker. To run as task on just one worker, add the task with a particular worker name in the function name, such as function_name_wrk1 and function_name_wrk2.

Broadcast (run the job on both wrk1 and wrk2) isn't available in Gearman either. You can however add several jobs, one for each function_name_<workername>, as long as you know the different worker names ahead of time.
