1. Download and extract binary
   curl -O https://dl.gitea.io/gitea/1.12.4/gitea-1.12.4-linux-arm64.xz
xz -d gitea-1.12.4-linux-arm64.xz
2. Move binary to path
   mv gitea-1.12.4-linux-arm64 /usr/local/bin/gitea
chmod +x /usr/local/bin/gitea
3. Create git user
   adduser --system --shell /bin/bash --gecos 'Git Version Control' --group --disabled-password --home /web/git git
4. Create directories
   mkdir -p /web/git/lib/{custom,data,log}
ln -s /web/git/lib /var/lib/gitea
chown -R git:git /web/git/lib
chmod -R 750 /web/git/lib
mkdir /web/git/etc
ln -s /web/git/etc /etc/gitea
chown root:git /web/git/etc
chmod 770 /web/git/etc
5. Create systemd unit in /etc/systemd/system/gitea.
   

   [Unit]
   Description=Gitea (Git with a cup of tea)
   After=syslog.target
   After=network.target
    
   [Service]
   RestartSec=2s
   Type=simple
   User=git
   Group=git
   WorkingDirectory=/web/git/lib/
   ExecStart=/usr/local/bin/gitea web --config /web/git/etc/app.ini
   Restart=always
   Environment=USER=git HOME=/web/git GITEA_WORK_DIR=/web/git/lib
    
   [Install]
   WantedBy=multi-user.target

6. Add unit it to start-full-system.target.wants
   ln -s /etc/systemd/system/gitea /etc/systemd/system/start-full-system.target.wants
   Alternatively, just enable:
   systemctl enable gitea.
7. Reload units and start Gitea
   systemctl daemon-reload
systemctl start gitea
8. Access web server on port 3000, i.e. http://athena:3000/
9. Click Register to start configuration
10. Choose SQLite3 or what have you
11. Change Site Title, SSH Server Domain & Port, Gitea Base URL
12. Server and Third-Party Service Settings: Disable Self-Registration

1. Stop gitea and change base URL. Change the following line in /web/git/etc/app.ini:
   

   ROOT_URL         = https://wgratz.net/gitea/

2. Insert into nginx config:
   

            location /gitea {
                    return 301 $scheme://$host/gitea/;
            }
            location ^~ /gitea/ {
                    proxy_pass http://localhost:3000;
                    rewrite /gitea(.*) $1 break;
            }
