How to configure and manage a Web server on Linux
As an operation and maintenance personnel or developer, configuring and managing a Web server on Linux is a very important skill . In this article, we will introduce how to configure and manage a web server using Apache and Nginx, and provide code examples.
1. Use Apache to configure and manage Web servers
Apache is a widely used Web server that can efficiently provide Web services on Linux. The following is the installation method and common configuration examples of Apache.
1. Install Apache
On CentOS distribution, you can use the following command to install Apache:
sudo yum install httpd
On Debian distribution, you can use the following command to install :
sudo apt-get install apache2
2. Configuring Apache
After installing Apache, you need to perform some basic configuration to ensure that the Web server can run normally.
2.1 Modify the main configuration file
The path of the main configuration file is /etc/httpd/conf/httpd.conf. In this file, you can modify commonly used configuration items, such as listening ports, virtual hosts, document root directories, etc.
The following are examples of some commonly used configuration items:
Modify the listening port:
Listen 80
Add a virtual host:
<VirtualHost *:80> ServerName www.example.com DocumentRoot /var/www/example.com </VirtualHost>
Modify the document root directory:
DocumentRoot "/var/www/html" <Directory "/var/www/html"> AllowOverride None Require all granted </Directory>
2.2 Create a virtual host
Creating a virtual host for a Web server is a very useful function, which allows the same server to run multiple different websites. Here is an example of how to create a basic virtual host:
<VirtualHost *:80> ServerName www.example.com DocumentRoot /var/www/example.com ErrorLog /var/log/httpd/example.com-error_log CustomLog /var/log/httpd/example.com-access_log combined </VirtualHost>
Where * means listening for requests on all network interfaces. ServerName represents the domain name or IP address corresponding to the virtual host. DocumentRoot represents the file directory corresponding to the virtual host. ErrorLog is used to record server error information, and CustomLog is used to record access logs.
2. Use Nginx to configure and manage the web server
Nginx is a high-performance web server that supports multiple protocols, such as HTTP, HTTPS, SMTP, POP3, etc. The following is the installation method and common configuration examples of Nginx.
1. Install Nginx
On CentOS distribution, you can use the following command to install Nginx:
sudo yum install nginx
On Debian distribution, you can use the following command to install :
sudo apt-get install nginx
2. Configure Nginx
After installing Nginx, some basic configuration is required to ensure that the web server can run normally.
2.1 Modify the main configuration file
The path of the main configuration file is /etc/nginx/nginx.conf. In this file, you can modify commonly used configuration items, such as listening ports, virtual hosts, document root directories, etc.
The following are examples of some commonly used configuration items:
Modify the listening port:
server { listen 80; server_name localhost; }
Add a virtual host:
server { listen 80; server_name www.example.com; root /var/www/example.com; }
Modify the document root directory:
location / { root /var/www/html; index index.html index.htm; }
2.2 Create a virtual host
In Nginx, the virtual host is called the server block. The following is an example of how to create a basic virtual host:
server { listen 80; server_name www.example.com; root /var/www/example.com; error_log /var/log/nginx/example.com-error.log; access_log /var/log/nginx/example.com-access.log combined; }
Among them, listen represents the listening port, server_name represents the domain name or IP address corresponding to the virtual host, root represents the file directory corresponding to the virtual host, and error_log uses To record server error information, access_log is used to record access logs.
Summary
In this article, we introduced how to configure and manage a web server using Apache and Nginx, and provided code examples. Whether using Apache or Nginx, configuring and managing a web server are very basic and important skills. Hope this article is helpful to readers.

Maintenance mode is a special operating level entered in Linux systems through single-user mode or rescue mode, and is used for system maintenance and repair. 1. Enter maintenance mode and use the command "sudosystemctlisolaterscue.target". 2. In maintenance mode, you can check and repair the file system and use the command "fsck/dev/sda1". 3. Advanced usage includes resetting the root user password, mounting the file system in read and write mode and editing the password file.

Maintenance mode is used for system maintenance and repair, allowing administrators to work in a simplified environment. 1. System Repair: Repair corrupt file system and boot loader. 2. Password reset: reset the root user password. 3. Package management: Install, update or delete software packages. By modifying the GRUB configuration or entering maintenance mode with specific keys, you can safely exit after performing maintenance tasks.

Linux network configuration can be completed through the following steps: 1. Configure the network interface, use the ip command to temporarily set or edit the configuration file persistence settings. 2. Set up a static IP, suitable for devices that require a fixed IP. 3. Manage the firewall and use the iptables or firewalld tools to control network traffic.

Maintenance mode plays a key role in Linux system management, helping to repair, upgrade and configuration changes. 1. Enter maintenance mode. You can select it through the GRUB menu or use the command "sudosystemctlisolaterscue.target". 2. In maintenance mode, you can perform file system repair and system update operations. 3. Advanced usage includes tasks such as resetting the root password. 4. Common errors such as not being able to enter maintenance mode or mount the file system, can be fixed by checking the GRUB configuration and using the fsck command.

The timing and reasons for using Linux maintenance mode: 1) When the system starts up, 2) When performing major system updates or upgrades, 3) When performing file system maintenance. Maintenance mode provides a safe and controlled environment, ensuring operational safety and efficiency, reducing impact on users, and enhancing system security.

Indispensable commands in Linux include: 1.ls: list directory contents; 2.cd: change working directory; 3.mkdir: create a new directory; 4.rm: delete file or directory; 5.cp: copy file or directory; 6.mv: move or rename file or directory. These commands help users manage files and systems efficiently by interacting with the kernel.

In Linux, file and directory management uses ls, cd, mkdir, rm, cp, mv commands, and permission management uses chmod, chown, and chgrp commands. 1. File and directory management commands such as ls-l list detailed information, mkdir-p recursively create directories. 2. Permission management commands such as chmod755file set file permissions, chownuserfile changes file owner, and chgrpgroupfile changes file group. These commands are based on file system structure and user and group systems, and operate and control through system calls and metadata.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
