Install GitBucket

 

 1. Login to your VPS via SSH

ssh user@vps_IP

2. Update the system and install necessary packages

[user]$ sudo apt-get update && sudo apt-get -y upgrade
[user]$ sudo apt-get install software-properties-common git nano wget

3. Install Java 8

To add the webupd8team repository to your sources list and install the latest Oracle Java 8 JDK, run the following commands:

[user]$ sudo add-apt-repository ppa:webupd8team/java
[user]$ sudo apt-get update
[user]$ sudo apt-get install oracle-java8-installer

To check if JAVA has been properly installed on your Ubuntu 16.04 VPS run java -version, and the output should be similar to the following:

[user]$ java -version
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

4. Install GitBucket

Create a new GitBucket user:

[user]$ sudo adduser --gecos 'Gitbucket User' gitbucket

GitBucket will store all the git repositories in the home directory of the user who will launch the application.

Download latest gitbucket.war from Github. At the time of writing, the latest version is version 4.4.

[user]$ sudo wget -O /home/gitbucket/gitbucket.war https://github.com/gitbucket/gitbucket/releases/download/4.4/gitbucket.war
[user]$ sudo chown -R gitbucket: /home/gitbucket

5. Create systemd service

To create a new systemd service for GitBucket, open your editor of choice and create a new file:

[user]$ sudo nano /etc/systemd/system/gitbucket.service

and add the following code lines:

[Unit]
Description=GitBucket service
After=syslog.target
After=network.target

[Service]
User=gitbucket
ExecStart=/usr/bin/java -jar /home/gitbucket/gitbucket.war --port=8080 --host=127.0.0.1

[Install]
WantedBy=multi-user.target

Start the GitBucket server and set it to start automatically on boot:

[user]$ sudo systemctl enable gitbucket.service
[user]$ sudo systemctl start gitbucket.service

To verify the unit started, run systemctl status gitbucket.service and you should see something like below:

● gitbucket.service - GitBucket service
   Loaded: loaded (/etc/systemd/system/gitbucket.service; enabled; vendor preset: enabled)
   Active: active (running) since Fri 2016-09-09 18:25:18 CDT; 2s ago
 Main PID: 3578 (java)
   CGroup: /system.slice/gitbucket.service
           └─3578 /usr/bin/java -jar /home/gitbucket/gitbucket.war --port=8080 --host=127.0.0.1

6. Install and configure Nginx

To install the latest stable version of Nginx available on the Ubuntu repositories, run:

[user]$ sudo apt-get -y install nginx

Generate a self signed ssl certificate:

[user]$ sudo mkdir -p /etc/nginx/ssl
[user]$ cd /etc/nginx/ssl
[user]$ sudo openssl genrsa -des3 -passout pass:x -out gitbucket.pass.key 2048
[user]$ sudo openssl rsa -passin pass:x -in gitbucket.pass.key -out gitbucket.key
[user]$ sudo rm gitbucket.pass.key
[user]$ sudo openssl req -new -key gitbucket.key -out gitbucket.csr
[user]$ sudo openssl x509 -req -days 365 -in gitbucket.csr -signkey gitbucket.key -out gitbucket.crt

[user]$ sudo openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048
If you don’t want to get warnings associated with self-signed SSL Certificates, you can purchase a trusted SSL certificate here.

Next, create a new Nginx server block:

[user]$ sudo nano /etc/nginx/sites-available/myGitbucket.com

server {
    listen 443 ssl http2;
    server_name myGitbucket.com;

    location / {
        proxy_pass              http://127.0.0.1:8080;
        proxy_set_header        Host $host;
        proxy_set_header        X-Real-IP $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout   150;
        proxy_send_timeout      100;
        proxy_read_timeout      100;
        proxy_buffers           4 32k;
        client_max_body_size    500m; # Big number is we can post big commits.
        client_body_buffer_size 128k;
    }

    ssl on;
    ssl_certificate     /etc/nginx/ssl/gitbucket.crt;
    ssl_certificate_key /etc/nginx/ssl/gitbucket.key;
    ssl_dhparam  /etc/nginx/ssl/dhparam.pem;

    ssl_session_timeout 5m;
    ssl_ciphers  EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;

    access_log  /var/log/nginx/mygitbucket.access.log;
    error_log   /var/log/nginx/mygitbucket.error.log;

}

server {
    listen      80;
    server_name myGitbucket.com;

    add_header Strict-Transport-Security max-age=2592000;
    rewrite ^ https://$server_name$request_uri? permanent;
}

Activate the server block by creating a symbolic link :

[user]$ sudo ln -s /etc/nginx/sites-available/myGitbucket.com /etc/nginx/sites-enabled/myGitbucket.com

Test the Nginx configuration and restart nginx:

[user]$ sudo nginx -t
[user]$ sudo systemctl start nginx

Open http://myGitbucket.com/ in your favorite web browser and you should see the GitBucket home page. The default username and password are both root.
