Static Site Generator, SSR And Other Framework For Site Generation

Posted on | by Oleg K.

Based on Vue.js

VuePress

VuePress is composed of two parts: a minimalistic static site generator (opens new window) with a Vue-powered theming system and Plugin API, and a default theme optimized for writing technical documentation. It was created to support the documentation needs of Vue’s own sub projects.

Each page generated by VuePress has its own pre-rendered static HTML, providing great loading performance and is SEO-friendly. Yet, once the page is loaded, Vue takes over the static content and turns it into a full Single-Page Application (SPA). Extra pages are fetched on demand as the user navigates around the site.

Base on Go

Hugo

Hugo is a fast and modern static site generator written in Go, and designed to make website creation fun again.

Hugo is a general-purpose website framework. Technically speaking, Hugo is a static site generator. Unlike systems that dynamically build a page with each visitor request, Hugo builds pages when you create or update your content. Since websites are viewed far more often than they are edited, Hugo is designed to provide an optimal viewing experience for your website’s end users and an ideal writing experience for website authors.

Websites built with Hugo are extremely fast and secure. Hugo sites can be hosted anywhere, including Netlify, Heroku, GoDaddy, DreamHost, GitHub Pages, GitLab Pages, Surge, Firebase, Google Cloud Storage, Amazon S3, Rackspace, Azure, and CloudFront and work well with CDNs. Hugo sites run without the need for a database or dependencies on expensive runtimes like Ruby, Python, or PHP.

How to install SSL (Let’s Encrypt) for the HestiaCP admin panel

Posted on | by Oleg K.

Сurrent information for 2024 year and later

Need run only one command in terminal for root user in any directory: 

v-add-letsencrypt-host

Old instuction:

When you go to panel url with port 8083 — you can see SSL error in your browser.

Here’s what you can do to fix that:

1. If you don’t have WEB domain — add WEB Domain in panel. I will use my domain codebe.com for example.

2. Go to WEB domain edit which one uses for panel:

Hestiacp add ssl to panel step 1

3. Enable SSL certificate for domain:

Hestiacp add ssl to panel step 2

4. Connect to your server over SSH.

5. Get information for changing hestia-nginx config. Copy full path to certificate and key for you domain, for example, I have this path:

/home/codebe/conf/web/codebe.com/ssl

And I’ve this files in current directory:

799435-codebe.com.crt
799435-codebe.com.key

6. Open file in your favorite text editor:

/usr/local/hestia/nginx/conf/nginx.conf

7. Change parameters for hestia-nginx server:

....
server {
    ....
    ssl_certificate      /home/codebe/conf/web/codebe.com/ssl/799435-codebe.com.crt;
    ssl_certificate_key  /home/codebe/conf/web/codebe.com/ssl/799435-codebe.com.key;
    ....
}
....

8. Restart HestiaCP (it’s working for Debian 11):

service hestia restart

9. Well done!

Resolve Error (AWS Free Tier and Terraform): Error launching source instance: VPCIdNotSpecified: No default VPC for this user. GroupName is only supported for EC2-Classic and default VPC.

Posted on | by Oleg K.

When you use Amazon Free Tier period and want to run free EC2 instance and when you get error:

Error: Error launching source instance: VPCIdNotSpecified: No default VPC for this user. GroupName is only supported for EC2-Classic and default VPC.

You need to create Security Group resource (example for port 80 for http server):

resource "aws_security_group" "allow_http" {
  name        = "allow_http"

  ingress {
    from_port        = 80
    to_port          = 80
    protocol         = "tcp"
    cidr_blocks      = ["0.0.0.0/0"]
    ipv6_cidr_blocks = ["::/0"]
  }

  egress {
    from_port        = 0
    to_port          = 0
    protocol         = "-1"
    cidr_blocks      = ["0.0.0.0/0"]
    ipv6_cidr_blocks = ["::/0"]
  }
}

After you can check and load network block device kernel-module:

rmmod nbd
modprobe nbd max_part=8

Then you connect image:

qemu-nbd -c /dev/nbd0 image.vdi

And mount (don’t forget create mount directory /media/image):

mount /dev/nbd0p1 /media/image

And unmount:

qemu-nbd -d /dev/nbd0
