How do I get this darn thing installed? None of the install instructions work when you use the easy script thing. I keep getting an error in ansible-playbook like this:
sudo python3 install.py --production --user erpadmin

This will create an Ubuntu frappeadmin user. You don’t have to wait to enter mysql root password, and ERPNext Administrator password because you supplied them with the prompt.
After this goes through, issue the following command to setup the frappeadmin user.
sudo usermod -aG sudo frappeadmin
sudo passwd frappeadmin (make password for frappeadmin)
su - frappeadmin (this will use frappeadmin as the sudo user, and go to its home directory)
cd frappe-bench
You can issue bench or Ubuntu commands at this point.
When you log in to Ubuntu, you login using frappeadmin user.
It is also good to issue this command
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
I was logged in as erpadmin when I ran the command. erpadmin already had full sudo privileges.
The reason the install bombed was because it could not write to /proc/sys/vm/swappiness. I had to delete the last 2 lines in main.yaml to tell it to not bother modifying swappiness.
Are you using OpenVZ VPS? i.e. no swap is allowed by the host
if no, there’s something with redis nowadays to be installed with Ubuntu 18.04
I don’t know why! but you can continue after disable IPv6.
make sure redis is running before you run the install script again.
Simple workaround is already posted some time back.
nano /etc/redis/redis.conf
# locate follwoing
bind 127.0.0.1 ::1
# simply remove it or comment it by adding # in front of the line. it will look like following:
# bind 127.0.0.1 ::1
# Then restart installation again
Above steps fix your problem with redis server which fails to install when there is no IPv6 or misconfiguration with IPv6 on OS level.
This is the reason why your install bombed. You used the same user as the one you logged in. You have to use another user (not yet existing) for frappe. This user that you indicate in the install command option will be made by the Easy Install for you.
After the installation, you made this new frappe user into a sudo user, give it a password, and su into its home directory.
This was a gotcha that got me when I started ERPNext, and this is what led me down the maze of manual installation procedures.
Now, to install Ubuntu 18 (don’t use 16 anymore or 19 yet), I just wget the install.py and run the easy install command and have coffee.
After that I do frappe user sudo commands, the ENOSPC fix, and Redis configuration fix.
No, this had nothing to do with ipv6. It has to do with setting swappiness. IPv6 WAS enabled and it installed fine after I hand-tweaked the main.yaml file
