GitList Installation

Download GitList from https://github.com/patrikx3/gitlist/releases and decompress to your /var/www/gitlist folder, or anywhere else you want to place GitList.
Rename the config.example.ini-example file to config.ini.
Open up the config.ini and configure your installation. You'll have to provide where your repositories are located and the base GitList URL.
Create the cache folder and give read/write permissions to your web server user:

cd /var/www/gitlist
mkdir -p cache
chmod 777 cache

That's it, installation complete!

Webserver configuration

Apache is the "default" webserver for GitList. You will find the configuration inside the .htaccess file. However, nginx and lighttpd are also supported.

To make it to be more secure: All PHP files will be in the root and only index.php, images, icons, svg, css, jsbundle files will be in the public subdir.

nginx server.conf

server {
    server_name MYSERVER;
    access_log /var/log/nginx/MYSERVER.access.log combined;

    root /var/www/DIR/public;
    index index.php;

    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;

    location ~* ^/index.php.*$ {
        fastcgi_index index.php;

lighthttpd

I do not use lighthttpd, but you know what I mean. Make sure only, the gitlist/public folder should be enabled.

# GitList is located in /var/www/gitlist/
server.document-root        = "/var/www"

url.rewrite-once = (
    "^/gitlist/web/.+" => "$0",
    "^/gitlist/favicon\.ico$" => "$0",
    "^/gitlist(/[^\?]*)(\?.*)?" => "/gitlist/index.php$1$2"
)

hiawatha

I do not use hiawatha, but you know what I mean. Make sure only, the gitlist/public folder should be enabled.
