Three ways to configure Nginx virtual hosts (based on domain names)

Nginx supports three ways to configure virtual hosts: IP-based virtual host configuration, port-based virtual host configuration, and domain name-based virtual host configuration.

3. Nginx domain name-based virtual host configuration

Using domain name-based virtual host configuration is a popular method. Multiple domain names can be configured on the same IP and all accessed through port 80.

3.1 Assume that the server has an IP address of 192.168.2.155

[root@localhost ~]# ifconfig ens33:5 192.168.2.155/24 up
[root@localhost ~]# ifconfig
ens33:5: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
  inet 192.168.2.155 netmask 255.255.255.0 broadcast 192.168.2.255
  ether 00:0c:29:16:90:ae txqueuelen 1000 (Ethernet)

3.2 The domain name corresponding to 192.168.2.155 is as follows. Configure the host file of the host for easy testing

[root@localhost ~]# vim /etc/hosts
[root@localhost ~]# cat /etc/hosts|grep 192.168.2.155
192.168.2.155 www.oa.com
192.168.2.155 www.bbs.com
192.168.2.155 www.test.com

3.3 Create a root directory for the virtual host to store web pages and create the homepage file index.html

[root@localhost ~]# cd /data/www/
[root@localhost www]# mkdir www.oa.com
[root@localhost www]# mkdir www.bbs.com
[root@localhost www]# mkdir www.test.com
[root@localhost www]# echo www.oa.com > www.oa.com/index.html
[root@localhost www]# echo www.bbs.com > www.bbs.com/index.html
[root@localhost www]# echo www.test.com > www.test.com/index.html

3.4 Modify nginx.conf and include the virtual host configuration file into the main file

[root@localhost /]# cd /usr/local/nginx/conf/
[root@localhost conf]# ls
fastcgi.conf fastcgi_params koi-utf mime.types nginx.conf scgi_params uwsgi_params win-utf
fastcgi.conf.default fastcgi_params.default koi-win mime.types.default nginx.conf.default scgi_params.default uwsgi_params.default
[root@localhost conf]# vim nginx.conf

Add the following configuration to the end of the nginx.conf file

# Find the following content in the http section and delete the "#" in front of each line
 log_format main '$remote_addr - $remote_user [$time_local] "$request" '
      '$status $body_bytes_sent "$http_referer" '
      '"$http_user_agent" "$http_x_forwarded_for"';

# Add the following statement before the last "}" at the end of the configuration file, as shown below include vhost/*.conf

3.5 Edit the configuration file for each domain name (configuration file for each virtual host)

[root@localhost conf]# cd vhost/
[root@localhost vhost]# cat www.oa.com.conf
 server {
  listen 192.168.2.155:80;
  server_name www.oa.com;

  access_log /data/logs/www.oa.com.log main;
  error_log /data/logs/www.oa.com.error.log;

  location / {
   root /data/www/www.oa.com;
   index index.html index.htm;
  }
 }

[root@localhost vhost]# cat www.bbs.com.conf
 server {
  listen 192.168.2.155:80;
  server_name www.bbs.com;

  access_log /data/logs/www.bbs.com.log main;
  error_log /data/logs/www.bbs.com.error.log;

  location / {
   root /data/www/www.bbs.com;
   index index.html index.htm;
  }
 }

[root@localhost vhost]# cat www.test.com.conf
 server {
  listen 192.168.2.155:80;
  server_name www.test.com;

  access_log /data/logs/www.test.com.log main;
  error_log /data/logs/www.test.com.error.log;

  location / {
   root /data/www/www.test.com;
   index index.html index.htm;
  }
 }

[root@localhost vhost]# cat /data/www/www.oa.com/index.html
www.oa.com
[root@localhost vhost]# cat /data/www/www.bbs.com/index.html
www.bbs.com
[root@localhost vhost]# cat /data/www/www.test.com/index.html
www.test.com

3.6 Create a log file, otherwise nginx cannot be started

[root@localhost /]# mkdir -p /data/logs
[root@localhost /]# touch /data/logs/www.oa.com.log
[root@localhost /]# touch /data/logs/www.oa.com.error.log
[root@localhost /]# touch /data/logs/www.bbs.com.log
[root@localhost /]# touch /data/logs/www.bbs.com.error.log
[root@localhost /]# touch /data/logs/www.test.com.log
[root@localhost /]# touch /data/logs/www.test.com.error.log
[root@localhost /]# ls /data/logs/
www.oa.com.error.log www.bbs.com.error.log www.test.com.error.log
www.oa.com.log www.bbs.com.log www.test.com.log

3.7 Test the configuration file before starting nginx

[root@localhost /]# cd /usr/local/nginx/sbin/
[root@localhost sbin]# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
# Start nginx
[root@localhost sbin]# ./nginx

3.8 Test Files

[root@localhost vhost]# curl http://www.oa.com
www.oa.com
[root@localhost vhost]# curl http://www.bbs.com
www.bbs.com
[root@localhost vhost]# curl http://www.test.com
www.test.com

Appendix: Problems during configuration

1. Problems that occurred during the final test

[root@localhost ~]# curl http://www.oa.com
curl: (7) Failed connect to www.oa.com:80; Connection refused

Solution:

Check whether Nginx is listening on the corresponding port.

[root@localhost ~]# netstat -lnt
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN

tcp6 0 0 :::111 :::* LISTEN
tcp6 0 0 :::22 :::* LISTEN
tcp6 0 0 :::23 :::* LISTEN
tcp6 0 0 ::1:25 :::* LISTEN

1. When configuring the virtual host file, add the listening IP address. Each virtual host configuration file is the same.

listen 192.168.2.155:80;

2. Restart the server after configuration is complete
