Multiple Bench Instance

Hello,

Is it possible to create multiple instance of bench with different versions on one server ?

Yes, it is possible to setup multiple benches on one server.
I’ve one master bench and one develop bench on my machine.

How u do that pls I am in need to do this I m currently in develop branch and using the same for public use for my organization If I could use seperately then it will be very helpful.

thanx in advance

Hi revant_one,

they both bench have different versions ? And if it have then can you give us a step for installing multiple versions of bench on one server and how you have managed bench file in server bin directory ?

I have the same question.

I am currently using multiple benches on my development machine. This is easy, because i am using only one bench at time, which i start with ‘bench start’ while developing.

The 1000$-Question is now how to setup multiple benches in production mode on one server.
This use case is different, because these multiple benches are sharing the nginx and so far while they are running parallel.

I have no idea how to setup this scenario.

It is very important for setting up staging environments (dev/test/production) on one server.

I’m also using it for development.

Production environment I haven’t tried.
What I can think of is setting up production benches and linking config files as per the bench names.

https://frappe.github.io/frappe/user/en/bench/guides/setup-production.html

e.g. for supervisor setup

cd ~/frappe-bench-master
bench setup supervisor
sudo ln -s `pwd`/config/supervisor.conf /etc/supervisor/conf.d/frappe-bench-master.conf

cd ~/frappe-bench-develop
bench setup supervisor 
sudo ln -s `pwd`/config/supervisor.conf /etc/supervisor/conf.d/frappe-bench-develop.conf

repeat this with nginx

For setting up multiple benches this I used :

bench init frappe-bench-1
bench init frappe-bench-2
bench init frappe-bench-3

Hello revant_one,

Can you give me steps for install multiple version of bench for development server.

Should we need multiple bench for production.
We have separate bench for every frappe-bench, but schedular is not working properly .

there must be multiple processes running for sudo supervisorctl status

executing bench console in different frappe-bench-* directories starts the respective frappe-bench environment

does executing python functions via separate bench console work as expected?

ERPNext is running fine, we have issue with email sending.

If we send email, then some time its not send, some time its delivery after 1day(approximate)

can you try setting different ports for redis_*.conf?

e.g.
frappe-bench/config/redis_.conf has ports 11000, 12000, 13000
haffrappe-bench/config/redis_
.conf has ports 11001, 12001, 13001
clfrappe-bench/config/redis_*.conf has ports 11002, 12002, 13002

@revant_one
Thanks, thats my core question.

I have setup different port and process name, Now I have also setup different port for redis.

Now, one more question, in nginx config I have changes 8000 to 8001, should I change 9000 to 9001 (socket port)

@revant_one thanks
I have done single bench and multi frappe on one server,
Now all process are running.

There is still lac of configuration & setup document,
I have updated following two wiki, it will help if some one can review it.

Now we are facing new issue.

Mysql stopped working after some interval.

Error is Can not allocate memory

I have checked this, Erpnext is Hanging upto 30 minutes. We are using AWS-4 Cores & memory 16GB
But doesn’t get any solution.

As you keep adding running benches memory consumption will increase.

Check it with 0,1,2,n benches

run command

free -h

Allocate more memory.

Temporary fix, add Swap refer : https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-16-04

If you are planning to keep adding more benches, separate file storage, database and compute.

  1. Get high memory Database (Amazon RDS)
  2. Mount network filesystem (Amazon EFS) on /home/user/benches/ so that all the benches, site/files will be added on mounted scale-able storage

Hi,

think that you are better off using docker to launch multiple instances of bench.

Is this something people would find useful? I can release my docker images if there is demand… it currently is baked in with my infrastructure keys. Will do it if there are 10 likes!

Is it solve if we use 16GB RAM & 256 GB SSD.

On this current server we have 2GB RAM.
