It is not working.
I tried with the virtual box instance (a) Production one and (b) development one.
not one time, couple of time last few days I download and install the virtual instance
Some time back, it worked perfectly, now I guess it has something to do with the virtual instance itself, hope some one from ERPNext check the files and confirm
Thanks

@caygri Can you specify the exact steps to reproduce the error?? Which commands did you use to install ERPNext? The error log you posted isn’t helpful. Please post the last part if some error popped up. Did you see the message ‘ERPNext has been installed successfully’.
If you installed using the --production flag, it’ll be accessible on YOUR_IP, and if you’ve installed using the --develop flag, you’ll have to run the bench start command from the frappe-bench folder and only then it’ll be accessible on the YOUR_IP:8000.
@jjk_saji can you post an error log? It’ll help us in debugging the issue. 
i follow step by step your official tutorial. GitHub - frappe/bench: CLI to manage Multi-tenant deployments for Frappe apps
and yes i see the messagge "ERPNext has been installed successfully’.
Only warning I have it’s this
[WARNING]: Host file not found: /etc/ansible/hosts
[WARNING]: provided hosts list is empty, only localhost is available
Which of these commands did you use?
sudo python install.py --develop
or
sudo python install.py --production
develop. it’s wrong?
i restore my vps and try with --production and show this error

@codingCoffee
Thanks for the reply. I will state the steps
I have used the virtual machine image from the download page “https://erpnext.com/download”
Then I opened (imported ) it to virtual box ( couple of times, I changed the network setting to bridge, some times I did with the default network settings
Then started with the virtual box instance
once the instance is up, I logged using ‘frappe’ and found what is my ip address is
then I went to the host machine, types the IP address and the port IP:8080
got the message server not accessible
For trouble shooting I again logged into the guest (erpnext ) instance and from the command line, gave “telnet IP 8080” I got message connection closed by foreign host, this means the service which has to using the port 8080 not running.
This step I have done so many time, since yesterday and today
Hope I know where it is gone wrong
thanks
Hey @jjk_saji,
I’m still not able to debug the issue. Can you mention your system specifications? Where are you running the virtualbox instance?
Here’s what I tried to reproduce the issue:
ERPNext-Production.ova
localhost:8080 in my browser and I was able to access it.I also tried the same with the development instance:
ERPNext-Dev.ova
frappe using password frappe
frappe-bench directory using cd frappe-bench commandbench start
localhost:8000 in my browser and I was able to access it@caygri are you running the script as root user? I’m not able to reproduce the issue. Can you post a few lines above and below this as well
yes like a root user.
i try all installation.
I dont understand what is the problem.
Seems like your VPS is not allowing you to set up a SWAP file. Can you post a few lines above and below this as well.
@codingCoffee
when you mention
Opened localhost:8080 in my browser and I was able to access it.
it is from the guest or from the host you are tryin, default virtual box image which is downloaded do not have a GUI, from where did u run the browser.
It it not better to mention IP_Address:8080 than saying localhost
I installed VirtualBox on my PC, and started the ERPNext virtual machine. Then in my PC’s browser I was able to access it on localhost.
If you have a dedicated IP on which you’re using the Virtual Machine, in that case you can use [IP_Address] instead of localhost.
guy i’m confusing a need to open new discussion for my problem?
Hi @codingCoffee,

I am using a VPS from inmotionhosting and I am performing this operation as a root user. Any suggestions?
Please help, Thanks 
Can you try executing these commands, in your VPS, one by one, as root.
And post the error here log if any.
# dd if=/dev/zero of=/extraswap bs=1M count=1024
# mkswap /extraswap
# echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
# swapon -a
# echo 1 | tee /proc/sys/vm/swappiness
Hi,
I did and I think there were errors. This is the output from the first command -

I have this same error when using the easy Install on my VPS with Centos 7.
Here is my output of these commands - same error as my previous poster.
Any fix to that so far?
Thank you!

If I am not mistaken then some VPS do not allow swap or charge for it. VPS like Digital Ocean or Vultr do not prohibit it. ERPNext works smoothly on either.
Please check with your VPS provider as this does not relate to ERPNext.
I checked my Specs and I have 4GB RAM but just 1GB VSwap. Is that the cause?
I then tried to follow the first steps of creating manual swap file Like THIS Guide.
This is my output - saying lastly “Not permitted”:
[root@erp .bench]# fallocate -l 4G /swapfile
[root@erp .bench]# chmod 600 /swapfile
[root@erp .bench]# mkswap /swapfile
