Nginx virtual host configuration, manage multiple website portals

In the development process of the Internet, building your own website has become the choice of many people. However, as the number of websites increases, how to effectively manage multiple website entrances has become an important issue. The configuration of Nginx virtual host can help us achieve this goal.

Nginx is a high-performance web server and reverse proxy server with the ability to handle high concurrent requests. Its virtual hosting configuration allows one server to host multiple websites at the same time and forward different website requests to different back-end servers. Below we will introduce how to use Nginx to configure virtual hosts.

First, we need to make the corresponding settings in the Nginx configuration file. Generally speaking, Nginx configuration files are located in the /etc/nginx directory. We can open this file with any text editor and configure it.

In the configuration file, the settings of each virtual host need to be described using a server block. Each server block needs to specify the listening port and the domain name of the virtual host. For example:

server {
    listen 80;
    server_name www.example1.com;
    ...
}

server {
    listen 80;
    server_name www.example2.com;
    ...
}

In the above example, we defined two server blocks. One listens on port 80 and forwards requests to the www.example1.com website, and the other listens on port 80 and forwards requests to the www.example2.com website.

Next, we need to configure the root directory of the virtual host and other related parameters. For example:

server {
    listen 80;
    server_name www.example1.com;
    root /var/www/example1;
    ...
}

server {
    listen 80;
    server_name www.example2.com;
    root /var/www/example2;
    ...
}

In the above example, we specified the corresponding root directory for each domain name. In this way, when the user requests www.example1.com, Nginx will forward the request to the /var/www/example1 directory, and when the user requests www.example2.com, it will forward the request to the /var/www/example2 directory.

In addition to the root directory, we can also configure access logs, error pages and other related parameters. For example:

server {
    listen 80;
    server_name www.example1.com;
    root /var/www/example1;
    access_log /var/log/nginx/example1.access.log;
    error_log /var/log/nginx/example1.error.log;
    ...
}

server {
    listen 80;
    server_name www.example2.com;
    root /var/www/example2;
    access_log /var/log/nginx/example2.access.log;
    error_log /var/log/nginx/example2.error.log;
    ...
}

In the above example, we set up independent access logs and error logs for each virtual host. This allows us to monitor and analyze visits to each website.

Finally, we need to restart Nginx for the configuration to take effect. You can use the following command to restart Nginx:

sudo service nginx restart

Through the above configuration, we can access different websites through different domain names, and each website can have independent root directories, access logs and error logs.

To sum up, Nginx’s virtual host configuration can help us manage multiple website portals. By configuring the listening port, domain name, root directory, logs and other parameters, we can easily host and manage multiple websites. I hope this article can help everyone understand Nginx virtual host configuration.
