Document the public YP AB hashserv setup

New page

There are two hashserv instances running on on the Yocto Project autobuilder. The private read-write at '''hashserv.yocto.io:8686''' and the read-only public copy at '''hashserv.yocto.io:8687'''.

On a VM with 7.5GB of memory and 2 vcpus we created a 150GB fast volume and mounted it at /home/hashserv. Our hashserv.db hovers at about 35GB and has gone as high as 90GB. We setup up automated snapshots for backup.

Run some commands to set up a user and grab the code:
adduser --system hashserv
su - hashserv
git clone https://git.openembedded.org/bitbake
exit

Copy the following to /etc/systemd/system/hashserv.service

<nowiki># /etc/systemd/system/hashserv.service
[Unit]
Description=Bitbake Hash Server
After=network.target

[Service]
User=hashserv
WorkingDirectory=/home/hashserv
Type=simple
ExecStart=/usr/bin/python3 /home/hashserv/bitbake/bin/bitbake-hashserv --bind :8686

[Install]
WantedBy=multi-user.target</nowiki>

Copy the following to /etc/systemd/system/hashserv-readonly.service
<nowiki># /etc/systemd/system/hashserv-readonly.service
[Unit]
Description=Bitbake Read-Only Hash Server
After=network.target

[Service]
User=hashserv
WorkingDirectory=/home/hashserv
Type=simple
ExecStart=/usr/bin/python3 /home/hashserv/bitbake/bin/bitbake-hashserv --bind :8687 --read-only

[Install]
WantedBy=multi-user.target</nowiki>

Some commands to enable and start the services:
systemctl daemon-reload
systemctl enable hashserv.service hashserv-readonly.service
systemctl start hashserv.service hashserv-readonly.service

Then we opened up the firewall for 8686/tcp to our autobuilder private network and opened 8687/tcp to the world. There is no authentication so it's important to use the correct firewall settings.
