    Setup Gitea on Raspberry Pi (3)

These instructions are based on this article: https://www.alexruf.net/2016/05/23/setup-gogs-git-service.html.
Setup Raspberry Pi with minimal Raspbian image. You need to connect to the HDMI port and set the following:
sudo raspi-config
There you need to enable the SSH server and you should change the hostname.
Then configure the correct timezone:
sudo dpkg-reconfigure tzdata
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

# Create a new user:
sudo adduser --disabled-login --gecos 'Gitea' git

# Install go 1.8.1
wget https://storage.googleapis.com/golang/go1.8.1.linux-armv6l.tar.gz
sudo tar -C /usr/local -xzf go1.8.1.linux-armv6l.tar.gz

# Change to user git:
sudo su - git

# Set environment variables
export PATH=/usr/local/go/bin:$PATH
export GOPATH="$HOME/"

# Download and build go-bindata
go get github.com/jteeuwen/go-bindata
cd $GOPATH/src/github.com/jteeuwen/go-bindata/go-bindata
export PATH=$GOPATH/src/github.com/jteeuwen/go-bindata/go-bindata:$PATH

# Download the latest gitea version:
go get -d -u code.gitea.io/gitea
cd $GOPATH/src/code.gitea.io/gitea

# Build it
TAGS="bindata sqlite" make generate build

# Now type `exit` to go back to pi user.

Create the file /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 web
Restart=always
Environment=USER=git HOME=/home/git

[Install]
WantedBy=multi-user.target
# Start gitea:
sudo systemctl enable gitea
sudo systemctl start gitea
Install and setup nginx with ssl

# Install and configure nginx (see https://gogs.io/docs/advanced/configuration_for_source_builds#setting-up-nginx-sever):
sudo apt-get install nginx -y
Edit /etc/nginx/sites-available/gitea and insert the following:
server {
    listen 443 ssl;
    server_name gitea <your-domain>;
    ssl_certificate     /etc/letsencrypt/live/<your-domain>/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/<your-domain>/privkey.pem;

    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;
    }
}

server {
    listen 80;
    server_name gitea <your-domain>;
    return 301 https://$host$request_uri;
}


Now we need to create the ssl certificates for the domains.
cd ~
wget https://dl.eff.org/certbot-auto
chmod a+x certbot-auto
sudo ./certbot-auto certonly --standalone -d <your-domain>
In order to update the certificates automatically, we need to create a cron job via sudo crontab -e and insert the following line:
0 1 2 * * sudo service nginx stop && sudo /home/pi/certbot-auto renew --dry-run && sudo service nginx start
This executes the three commands on every first day of a month at 2 AM.
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 rm /etc/nginx/sites-enabled/default
sudo service nginx restart
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.
Update Gitea

sudo su - git
export GOPATH="$HOME/"
export PATH=$GOPATH/src/github.com/jteeuwen/go-bindata/go-bindata:$PATH
export PATH=/usr/local/go/bin:$PATH
cd $GOPATH/src/code.gitea.io/gitea/
git checkout HEAD -- public/swagger.v1.json
go get -d -u code.gitea.io/gitea
TAGS="bindata sqlite" make generate build
exit
sudo systemctl restart gitea
