So, you're building a frontend application. It works perfectly on localhost. Then you deploy it to Dev, Staging, and Production, and suddenly you realize you're rebuilding your Docker image just to change API_URL from dev-api.com to prod-api.com.

Using Docker Compose, we can quickly achieve a self-hosted deployment of GitLab, boosting code management and CI/CD automation. GitLab Runner is the CI/CD component responsible for executing jobs.

1. Preparation

1. Install Docker & Docker Compose:

   sudo apt update
   sudo apt install -y docker.io docker-compose
   sudo systemctl enable docker --now

2. Configure Docker Registry Mirror (Optional, for better speeds in some regions):

   sudo mkdir -p /etc/docker
   sudo tee /etc/docker/daemon.json <<-'EOF'
   {
       "registry-mirrors": [
           "https://docker.1panel.live"
       ]
   }
   EOF
   sudo systemctl daemon-reload && sudo systemctl restart docker

3. Create Data Directories:

   mkdir -p /srv/gitlab/data /srv/gitlab/logs /srv/gitlab/config /mnt/host/gitlab-pages /etc/gitlab-runner

In a Linux environment, we can build robust server-client architectures using Sockets and multi-processing.

The Socket Communication Flow

Here is the lifecycle of a Socket connection:

Static libraries are embedded into the executable at compile time, while Dynamic libraries (ending in .so or .dll) are loaded at runtime.

The Comparison

1. Install CCAA (CentOS + Caddy + AriaNg + Aria2)

CCAA is a one-click script that sets up a complete download station.

1.1 Run the Script

Overseas Servers:

bash <(curl -Lsk https://raw.githubusercontent.com/helloxz/ccaa/master/ccaa.sh)

1. Installing WeEngine

1.1 Setting up the Environment with Baota Panel

Installing WeEngine requires a LAMP environment (Linux + Apache + MySQL + PHP). To save our precious life for more exciting things, we'll use the Baota Linux Panel to simplify this process.

1. Environment Setup

1.1 LAMP Stack

Installing MediaWiki requires a LAMP environment (Linux + Apache + MySQL + PHP). We'll use the Baota Linux Panel to make this painless. Life is too short to configure Apache conf files manually for the 100th time.
