Gitea

Gitea is a community managed fork of Gogs, lightweight code hosting solution written in Go and published under the MIT license.

Installation

Install the gitea or gitea-git^AUR package.

Gitea requires the use of a database backend, the following are supported:

Configuration

The user configuration file is located at /etc/gitea/app.ini and is created the first time Gitea is run. There is also an example configuration file located at /etc/gitea/app.example.ini.

See the Gitea docs for more configuration examples.

PostgreSQL

Install and configure PostgreSQL.

Choose between TCP or UNIX Socket, and jump to the corresponding section.

Note: When Gitea and PostgreSQL are on the same machine, you should use a Unix socket, as it is faster and more secure.

With TCP socket

Create the new user while connecting to the server as postgres user (you will be prompted for a password for the new user):

[postgres]$ createuser -P gitea

Create the Gitea database, owned by gitea user:

[postgres]$ createdb -O gitea gitea

PostgreSQL#Configure PostgreSQL to be accessible from remote hosts

Verify it works:

$ psql --host=ip_address --dbname=gitea --username=gitea --password

Configure Gitea either through the first-run installer or update app.ini:

/etc/gitea/app.ini

DB_TYPE             = postgres
HOST                = hostadress:port
NAME                = gitea
USER                = gitea
; Use PASSWD = `your password` for quoting if you use special characters in the password.
PASSWD              = password

With Unix socket

Create the new user while connecting to the server as postgres user:

[postgres]$ createuser gitea

Create the Gitea database, owned by gitea user:

[postgres]$ createdb -O gitea gitea

Setup the Unix socket by adding the following line to /var/lib/postgres/data/pg_hba.conf:

local    gitea           gitea           peer

Restart postgresql.service.

Verify it works:

[gitea]$ psql --dbname=gitea --username=gitea

Configure Gitea either through the first-run installer or update app.ini:

/etc/gitea/app.ini

DB_TYPE             = postgres
HOST                = /run/postgresql/
NAME                = gitea
USER                = gitea
PASSWD              =

MariaDB/MySQL

Note: MySQL socket support can be enabled by using /var/run/mysqld/mysqld.sock as the listen address.

The following is an example of setting up MariaDB, setting your desired password:

$ mysql -u root -p

mysql> CREATE DATABASE `gitea` DEFAULT CHARACTER SET `utf8mb4` COLLATE `utf8mb4_unicode_ci`;
mysql> CREATE USER `gitea`@'localhost' IDENTIFIED BY 'password';
mysql> GRANT ALL PRIVILEGES ON `gitea`.* TO `gitea`@`localhost`;
mysql> FLUSH PRIVILEGES;
mysql> \q

Try connecting to the new database with the new user:

$ mysql -u gitea -p -D gitea

Configure MariaDB either through the first-run installer or update app.ini:

/etc/gitea/app.ini

DB_TYPE  = mysql
HOST     = 127.0.0.1:3306 ; or /var/run/mysqld/mysqld.sock
NAME     = gitea
USER     = gitea
PASSWD   = password

Usage

Start/enable gitea.service, the webinterface should listen on http://localhost:3000.

When running Gitea for the first time it should redirect to http://localhost:3000/install.

Note: You might want to configure a reverse proxy to access remotely, e.g. nginx.

Note: If you want Gitea to listen on all interfaces, set HTTP_ADDR = 0.0.0.0 in /etc/gitea/app.ini.

Tips and tricks

Local Shell Client (tea)

With tea you can use the official cli-client of gitea. More information can be found at https://gitea.com/gitea/tea

Enable SSH Support

Make sure SSH is properly configured and running.

Setup your domain

You might want to set SSH_DOMAIN, e.g.:

/etc/gitea/app.ini

SSH_DOMAIN                 = git.domain.tld

Note: If you set the PROTOCOL to be unix, then you need to unset LOCAL_ROOT_URL or set it to http://unix/. See this comment

Configure SSH

By default Gitea will run as user gitea, as well this account will be used for ssh repository access. For ssh access to work, you have to enable PAM. Alternatively, you might have to unlock service account.

/etc/ssh/sshd_config

...
UsePAM yes
...

If you use AllowUsers in your SSH configuration, add AllowUsers gitea to it, e.g.:

/etc/ssh/sshd_config

...
AllowUsers archie gitea
...

Restart sshd.service if you use it (nothing to do if you use sshd.socket).

Disable HTTP protocol

By default, the ability to interact with repositories by HTTP protocol is enabled. You may want to disable HTTP-support if using SSH, by setting DISABLE_HTTP_GIT to true.

Binding on restricted ports

If you use the built-in SSH server and want Gitea to bind it on port 22, or if you want to bind Gitea webserver directly on ports 80/443 (that is in a setup without proxy), you will need to add a drop-in systemd unit override:

/etc/systemd/system/gitea.service.d/override.conf

[Service]
AmbientCapabilities=CAP_NET_BIND_SERVICE
CapabilityBoundingSet=CAP_NET_BIND_SERVICE
PrivateUsers=false

Enable Dark Theme

In the ui section, you can set the DEFAULT_THEME to arc-green for making the web interface use a dark background.

Configure nginx as reverse proxy

This article or section needs expansion.

Reason: Missing Apache HTTP Server/Caddy proxy example (Discuss in Talk:Gitea)

The following is an example of using nginx as reverse proxy for Gitea over unix socket (you need to provide the SSL certificate):

/etc/nginx/servers-available/gitea.conf

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name git.domain.tld;

    ssl_certificate /path/to/fullchain.pem;
    ssl_certificate_key /path/to/privkey.pem;

    location / {
        proxy_pass http://unix:/run/gitea/gitea.socket;
    }
}

Update the [server] and [session] section of app.ini:

/etc/gitea/app.ini

[server]
PROTOCOL                   = unix
DOMAIN                     = git.domain.tld
ROOT_URL                   = https://git.domain.tld
HTTP_ADDR                  = /run/gitea/gitea.socket
LOCAL_ROOT_URL             =

[session]
COOKIE_SECURE              = true

Note: You do not need to activate any SSL certificate options in /etc/gitea/app.ini.

For additional information and examples see Reverse Proxies section on Gitea documentation website [1].

Setup for custom data directory

As of now, you cannot use a custom path like /srv/gitea as your server home, since the shipped gitea.service unit file marks everything read-only.

To enable these custom paths, create a drop-in snippet with your server home directory as a new ReadWriteDirectories directive:

/etc/systemd/system/gitea.service.d/data-directory.conf

[Service]
ReadWriteDirectories=/srv/gitea

Then do a daemon-reload and restart gitea.service for the changes to take effect.

Troubleshooting

Database error on startup after upgrade to 1.5.0

A problem can appear after the upgrade to 1.5.0. The service will not start, and the following error is present in the logs:

/var/log/gitea/gitea.log

2018/08/21 16:11:12 [...itea/routers/init.go:60 GlobalInit()] [E] Failed to initialize ORM engine: migrate: do migrate: Sync2: Error 1071: Specified key was too long; max key length is 767 bytes

To fix this problem, run the following command as the `root` user on your MySQL/MariaDB server

$ mysql -u root -p

MariaDB> set global innodb_large_prefix = `ON`;

gitea should stop complaining about key size and startup properly.
