1. Introduction to Nginx
Nginx (engine x) is a high-performance HTTP and reverse proxy web server, and also provides IMAP/POP3/SMTP services. Nginx was developed by Igor Sysoyev for the second most visited Rambler.ru site in Russia (Russian: Рамблер). The public version 1.19.6 was released on December 15, 2020.
It releases its source code under a BSD-like license and is known for its stability, rich feature set, simple configuration files, and low system resource consumption. On January 25, 2022, nginx 1.21.6 was released.
Nginx is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server, released under the BSD-like protocol. Its characteristic is that it occupies less memory and has strong concurrency capability. In fact, the concurrency capability of nginx is better than other web servers of the same type.
2. Nginx dependency installation
Before installing Nignx, several dependency packages need to be installed: pcre, openssl, zlib, nginx.
If there is no network, then find the latest version of pcre on the sourceforge website (https://sourceforge.net/projects/pcre/)
Enter the command to download in the terminal, and download the installation package to the server /usr/src/ directory
Then find the compressed package and decompress it
tar -zxvf pcre-8.45.tar.gz
After the decompression is complete, enter the pcre directory, execute ./configure to compile, and after the compilation is complete, execute the make command
If there is a network, directly execute the command to download and install
yum install -y gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel
3. Nginx download
The latest stable version can be downloaded from the official website http://nginx.org/en/download.html
Upload the Nginx installation package to the virtual machine through xftp
Unzip the nginx installation package
tar -zxvf nginx-1.24.0.tar.gz
You can also download wget http://nginx.org/download/nginx-1.24.0.tar.gz through the command
. After the download is complete, you also need to decompress
4. Nginx configuration
Execute the command ./configure in the /usr/local/nginx/nginx-1.24.0 file directory
and then execute the make command
5. Start Nginx
Find the nginx directory in the virtual machine directory and find the sbin/ directory. You
need to start the Nginx file in the sbin/ directory, enter the sbin file and use the command ./nginx to start the program
(PS: close the command ./nginx - s stop
reload command ./nginx -s reload)
Access to the IP of the virtual machine, if the access fails, it may be due to the firewall, you need to close the firewall, or open the access port 80 of the firewall, you can
query and configure firewall-cmd --list-all through the command, where ports are set ports, you need Open running access to port 80
Use the command to set firewall-cmd --add-port=80/tcp --permanent to
restart the firewall systemctl reload firewalld
to view the status of the firewall systemctl status firewalld
to start the firewall systemctl start firewalld
to close the firewall systemctl stop firewalld
After restarting to set the port, restart the firewall, and check again that the port number has been set successfully.
Visit the virtual machine address again, as shown in the figure, Nginx starts successfully and can be accessed normally.
