How to deploy a virtual server? Zero basic operation step guide

for zero-based users who want to build personal websites, test applications or lightweight businesses, virtual servers are a very cost-effective choice, but many people will be discouraged by unfamiliar operating processes. This article will disassemble the whole process of virtual server deployment into easy-to-understand steps, from pre-preparation to final application launch, each link gives clear guidelines, even if there is no professional technical background, you can follow the construction and configuration of virtual servers, and easily start your own server use journey.

How to choose the right virtual server?

choosing the right virtual server is the first step in deployment, appropriate configuration can avoid waste of resources or insufficient performance, zero-based users need to focus on several core dimensions in combination with their own needs.

1. Select configuration parameters on demand

if it is to build a personal blog or a small test site, choose a virtual server with 1 core of 2G memory and 50G storage to meet the needs; if you want to deploy an e-commerce platform or an application with high traffic, it is recommended to choose at least 2 cores of 4G memory or more. At the same time, SSD storage is preferred, which can greatly improve the data read and write speed. In terms of bandwidth, 1-2M bandwidth for personal sites is sufficient, and commercial sites recommend choosing more than 3M bandwidth.

2, compare service providers and regional nodes

try to choose the Cloud as a Service provider with high visibility and after-sales services. The virtual server of such service providers is more stable, and technical support can be obtained in time if there is a problem. Regional nodes are recommended to be selected in the area where the target user is concentrated. For example, choosing domestic nodes for domestic users can effectively reduce network latency and improve access experience. At the same time, it is necessary to confirm whether the node has the qualification for filing to avoid subsequent compliance problems.

2. System installation and initialization of virtual server

select the virtual server, first to complete the system installation and basic initialization configuration, which is the basis for subsequent operations, the steps are simple and easy to use.

1, select and install the operating system

log in to the management console of Cloud as a Service provider, find the purchased virtual server, and enter the system image selection interface. Zero-based users are preferred to recommend CentOS or Ubuntu in the Linux system. These two systems have rich community resources, many tutorials and simple operation; if you are familiar with Windows systems, you can also choose Windows Server, but the resource occupation is relatively high. After selecting the image, click one-click to install, and wait 5-10 minutes to complete the system deployment.

2, complete the basic initialization configuration

the system is installed, first reset the login password. It is recommended to set a complex password containing letters, numbers and special characters to improve the security of the virtual server. Then open a remote connection, Linux system can use Xshell or Putty tools to log in through Internet Protocol Address, username and password; Windows system can directly use its own remote desktop connection function. After logging in, update the system patch, Linux the system executes the yum update or apt update command, Windows system completes the update in the settings to repair the system vulnerabilities.

The basic environment and security configuration of the virtual server

complete the system initialization, but also need to build a basic operating environment and security configuration, which can ensure the stable operation of the virtual server, to avoid malicious attacks.

1, build the basic environment for application operation

if you are deploying a PHP website, you need to install Apache or Nginx web server, PHP runtime environment and MySQL database on the virtual server. Zero-based users can use one-click installation scripts, such as LNMP or LAMP one-click packages of the Linux system, and only need to execute a command to complete the entire environment. There is no need to configure parameters one by one. If you deploy Python applications, you need to install the corresponding Python version and virtual environment to isolate the dependencies of different projects.

2, configure security groups and firewalls

log in to the Cloud as a Service console to enter the security group configuration interface, open only the necessary ports, such as port 80 of the website service, port 443 of HTTPS, port 22 or port 3389 of the remote connection, close all unused ports, reduce the risk of being attacked. At the same time, turn on the firewall that comes with the system. The Linux system can set rules through firewalld or iptables. The Windows system configures inbound rules in the firewall advanced settings to double ensure the cyber security of the virtual server.

IV. Application deployment and online verification of virtual servers

complete the basic configuration, you can deploy the target application and verify the online effect, which is the final link of virtual server deployment, you need to choose the corresponding operation mode according to the application type.

1, upload applications and configure

if it is a static website, you can upload HTML, CSS, JS and other files to the web root directory of the virtual server through FTP tools or remote connections, such as the default directory of Nginx is/usr/share/nginx/html; if it is a dynamic website, in addition to uploading program files, you need to import the corresponding backup files in the database, and modify the database connection information in the program configuration file to ensure that the application can read the data normally.

2, verify the application online effect

configuration is completed, enter the public Internet Protocol Address of the virtual server directly in the browser. If the application page can be displayed normally, the deployment is successful. Next, you can test the core functions of the application, such as the publication of articles on the website, the submission of forms, or the business process of the application, and confirm that all functions are running normally. If you want to use the domain name to access, you also need to complete the domain name resolution and filing, and point the domain name to the public IP of the virtual server.

To sum up, the core process of virtual server deployment can be summarized as selection, initialization, configuration, and deployment. Zero-based users only need to follow the steps step by step to successfully complete the construction. In actual operation, choose the appropriate virtual server configuration according to their own needs, pay attention to the security reinforcement link, and refer to the official documents and community tutorials. If you encounter problems, you can quickly master the deployment and use skills of virtual servers.
