How to build a containerized high-performance web server on Linux?

Introduction: With the rapid development of cloud computing, containerization technology has become a popular choice for modern application deployment. Building a containerized high-performance web server on Linux can not only improve the scalability and reliability of the application, but also save the use of hardware resources. This article will introduce how to use Docker and Nginx to build a containerized high-performance web server. .

1. Install Docker
To build a containerized web server on Linux, you first need to install Docker. Execute the following command in the terminal to install Docker:

sudo apt-get update
sudo apt-get install docker.io

After the installation is complete, you can execute the following command to check whether Docker is installed successfully:

docker --version

2. Make a Docker image

1. Create directories and files

Create a new directory to store our application files. Execute the following command in the terminal:

mkdir myapp
cd myapp

Create a file named Dockerfile in the myapp directory and open the file with a text editor:

touch Dockerfile

2. Writing Dockerfile

Write the following content in the Dockerfile:

# 使用基础镜像
FROM ubuntu:latest

# 更新软件源
RUN apt-get update

# 安装Nginx
RUN apt-get install nginx -y

# 复制配置文件到镜像
COPY nginx.conf /etc/nginx/nginx.conf

# 复制应用文件到镜像
COPY app /var/www/html

# 暴露端口
EXPOSE 80

# 启动Nginx服务
CMD ["nginx", "-g", "daemon off;"]

3. Write the configuration file and application file

Create it in the myapp directory created in the previous step Two files, one named nginx.conf and one named app.

Write the following content in nginx.conf:

worker_processes auto;
pid /run/nginx.pid;

events {
    worker_connections 1024;
}

http {
    server {
        listen 80;
        server_name localhost;
        root /var/www/html;
        index index.html;

        location / {
            try_files $uri $uri/ =404;
        }
    }
}

Write a simple HTML file in the app, such as index.html.

4. Build the Docker image

Back to the terminal, execute the following command to build the Docker image:

docker build -t myapp .

Among them, . means The directory where the Dockerfile is located, myapp is the name we gave the image.

3. Run the containerized web server
After the Docker image is built, you can run the containerized web server. Execute the following command:

docker run -d -p 80:80 myapp

Among them, -d means running the container in background mode, -p 80:80 means mapping port 80 of the host to port 80 of the container , myapp is the name of the image we built before.

At this point, we have successfully built a containerized high-performance web server on Linux. Applications on this server can be accessed by accessing the host's IP address or domain name.

Conclusion:
This article introduces how to use Docker and Nginx to build a containerized high-performance web server. Through containerization, we can more easily deploy and manage applications and improve application scalability and reliability. I hope this article can help everyone build a containerized web server on Linux.
