Nginx Windows detailed installation and deployment tutorial

1, Introduction to Nginx

Nginx (engine x) is a high-performance HTTP and reverse proxy server, as well as an IMAP/POP3/SMTP server. Nginx is Rambler.ru, the second most visited site in Russia by Igor sesoyev (Russian: Рамблер) Developed

It is also a lightweight Web server, which can be used as an independent server to deploy websites (similar to Tomcat). Its high-performance and low memory consumption structure is favored by many large companies, such as Taobao website.

Download it first and go directly to the official website http://nginx.org/en/download.html

 

 

 

Click to download. After the download, the installation starts. In fact, the official website has told you how to install. There are detailed instructions in "documentation - > nginx windows" on the right, which is only in English

 

2, Installation deployment

1. After downloading, unzip, run cmd, and use the command to operate. Do not double-click nginx.exe, nginx.exe, or nginx.exe directly

Be sure to start it in the dos window. Do not double-click nginx.exe directly. This will lead to invalid restart and stop of nginx after modifying the configuration. You need to manually close all nginx processes in the task manager and restart it

2. Use the command to reach the compressed directory of nginx

cd D:\SoftWare\Develop_SoftWare\nginx-1.20.2\nginx-1.20.2

3. It is normal for nginx service to flash when starting

start nginx

4. Check whether the task process exists, dos or open the task manager

tasklist /fi "imagename eq nginx.exe"

 

 

Open the task manager. You can't see the nginx.exe process in the process (it will be displayed here when you double-click nginx.exe). You need to open the details to see the hidden nginx.exe process

 

 

  If there is no error, it may be an error at startup. Check the log. error.log is the log file under the logs folder in the nginx directory

Common errors:

(1) Port number occupied

(2)nginx folder path contains Chinese

For other errors, see the description in the log

5. Modify the configuration file, enter the decompression directory, and click directly into the folder. There is no need to operate from dos

Find nginx.conf in the conf directory and open it with txt text. Find the server node and modify the port number. If necessary, you can modify the home directory. If not, you don't need to modify it

 

 

Save after modification. Use the following command to check whether the configuration file is correct, followed by the path of nginx.conf file. successful indicates that it is correct

nginx -t -c /nginx-1.15.2/conf/nginx.conf

If the program is not started, start nginx directly. If it has been started, use the following command to reload the configuration file and restart

nginx -s reload

Then open the browser to access the domain name and port just now http://localhost:8800 , the welcome page indicates that the deployment is successful

 

 

6. It is normal to close the nginx service and use the following command to see if the process has disappeared

Quick stop

nginx -s stop

Complete and orderly shutdown

nginx -s quit

 

3, Optimized configuration

  Open nginx.conf and configure it according to your needs. Some simple general tuning configurations are listed below

#user  nobody;
#==The number of work processes is generally set as the number of cpu cores
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    #==The maximum number of connections is generally set to cpu*2048
    worker_connections  1024;
}

    #gzip  on;

	    #Site listening port
        listen       80;

        server_name  localhost;

            proxy_set_header X-Real-IP $remote_addr;
            #Add the value of the $remote_addr variable after the client's "X-Forwarded-For" request header, separated by commas. If the client request does not carry the "X-Forwarded-For" request header, the value of the $proxy_add_x_forwarded_for variable will be the same as that of the $remote_addr variable  
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

            proxy_redirect off;
            
            #The browser has many restrictions on cookies. If the Domain part of the Cookie does not match the Domain of the current page, it cannot be written.
            #Therefore, if the domain name A is requested, the server proxy_pass es to the domain name B, and then the server B outputs A Cookie with Domian=B,
            #The front page still stays on the A domain name, so the browser cannot write the Cookie.
            
           #Not only the domain name, but also the browser has restrictions on Path. We often proxy_pass to a Path of the target server,
            #Do not expose this Path to the browser. At this time, if the Cookie of the target server is dead, the Path will also have the problem that the Cookie cannot be written.
            
            #Set the replacement text of the domain property in the "set cookie" response header. Its value can be a string, the pattern of a regular expression, or a referenced variable
