    Setup Gitea on Raspberry Pi (3b+)

These instructions are based on this article: https://www.alexruf.net/git/2016/05/23/setup-gogs-git-service.html.
Other instructions. https://hobbylad.wordpress.com/2018/02/16/gitea-git-server-setup-on-raspberry-pi/
Setup Raspberry Pi with minimal Raspbian image. You need to connect to the HDMI port and set the following:
Use Noobs to install Raspian.
Open menu Preferences > Raspberry Pi Settings
There you need to enable the SSH server and you should change the hostname.
Then configure the correct timezone:
Now log in via ssh and execute the following commands:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install zip git -y
Install nginx

# Might need to update sources.list if nginx package isn't found.
sudo pico /etc/apt/sources.list
# uncomment last line
sudo apt-get update

sudo apt-get install nginx -y
Create a new user:

sudo adduser --disabled-login --gecos 'Gitea' git
Install latest release of Go

git clone https://github.com/udhos/update-golang
cd update-golang
sudo ./update-golang.sh
Updating version of Go

From the pi user issue the following command.
sudo ./update-golang.sh
Then you will need to rebuild Gitea to use the updated version of Go.
Change to user git:

sudo su - git
Set environment variables

You will eventually need to add these environmental variables to each user pi, git, root

export PATH=$PATH:/usr/local/go/bin
export GOPATH=/home/git
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOPATH/src/github.com/go-bindata/go-bindata/go-bindata
export PATH=$PATH:$GOPATH/src/code.gitea.io/gitea

Download go-bindata

go get github.com/go-bindata/go-bindata
Download the latest gitea version:

go get -d -u code.gitea.io/gitea
Now type exit to go back to pi user

Build it under root user

sudo su - root
Reset environment variables above with root user

cd $GOPATH/src/code.gitea.io/gitea
TAGS="bindata sqlite" make generate build
Now type exit to go back to pi user.

Configure Gitea and Nginx

Create/Edit /etc/systemd/system/gitea.service and add the following content:

[Unit]
Description=Gitea
After=syslog.target
After=network.target
After=mariadb.service mysqld.service postgresql.service memcached.service redis.service

[Service]
# Modify these two values and uncomment them if you have
# repos with lots of files and get an HTTP error 500 because
# of that
###
#LimitMEMLOCK=infinity
#LimitNOFILE=65535
Type=simple
User=git
Group=git
WorkingDirectory=/home/git/src/code.gitea.io/gitea
ExecStart=/home/git/src/code.gitea.io/gitea/gitea web
Restart=always
Environment=USER=git HOME=/home/git

[Install]
WantedBy=multi-user.target
# Start gitea:
sudo systemctl enable gitea
sudo systemctl start gitea
Create/Edit /etc/nginx/sites-available/gitea and insert the following:

server {
    listen 80;
    server_name gitea;
    
    location / {
        client_max_body_size 364M;
        proxy_pass http://localhost:3000;
        proxy_connect_timeout 600;
        proxy_send_timeout 600;
        proxy_read_timeout 600;
        send_timeout 600;
        proxy_set_header X-Real-IP $remote_addr;
    }
}


Then enable the gitea nginx-site and restart the nginx server:
sudo ln -s /etc/nginx/sites-available/gitea /etc/nginx/sites-enabled/gitea
sudo service nginx restart
Update Gitea

sudo su - git

# Load environmental variables to $PATH as above

cd $GOPATH/src/code.gitea.io/gitea/
git checkout <branch>
go get -d -u code.gitea.io/gitea
exit
sudo su - root

# Load environmental variables to $PATH as above

cd $GOPATH/src/code.gitea.io/gitea
TAGS="bindata sqlite" make generate build
exit
sudo systemctl restart gitea
Create backup-script

Now we want to create a backup script that is run by crontab every day. To do so, create a new file called gitea-backup.sh and insert the following content (replace YOUR_SERVER/YOUR/DIR as well as USER and PASSWORD):
#!/bin/bash

# Create directory if it does not exist
mkdir -p git

# Mount NAS directory
sudo mount -t cifs //<your-nas>/Git git -o user=<your-nas-user>,pass=<your-password>

# Create backup directory if it does not exist and cd into it
mkdir -p git/gitea-backups

# Run the backup job
sudo zip -r "git/gitea-backups/gitea-backup-$(date +"%Y-%m-%d %H-%M-%S").zip" /home/git/src/code.gitea.io/gitea/custom /home/git/src/code.gitea.io/gitea/data /home/git/gitea-repositories

# Remove all files, keeping the last recent one and cd back
cd git/gitea-backups
ls -t1 . | tail -n +3 | xargs -d '\n' rm -f
cd ../..

# Allow changing the backup dir and files
sudo chmod -R 777 git/gitea-backups

# Clean up everything
sudo umount git
rmdir git
Now chmod +x gitea-backup.sh and create a new crontab entry:
crontab -e

# Now add the following line:
0 0 * * * /home/pi/gitea-backup.sh
This calls our script everyday at 0:00 AM, creates a gogs dump and copies it to our network share.
Virtual memory exhausted: Cannot allocate memory

https://www.bitpi.co/2015/02/11/how-to-change-raspberry-pis-swapfile-size-on-rasbian/
sudo nano /etc/dphys-swapfile
Default value in Raspbian is:
CONF_SWAPSIZE=100
Change to:
CONF_SWAPSIZE=1024
Restart swapfile service
sudo /etc/init.d/dphys-swapfile stop
sudo /etc/init.d/dphys-swapfile start

Check memory+swap
free -m
You should probably switch the swapsize back once the installation is complete to avoid potential disk issues.
