How to configure Nginx virtual host on CentOS

Experimental environment

A minimally installed centos 7.3 virtual machine

Configuring the basic environment

1. Install nginx

yum install -y epel-*
yum isntall -y nginx vim

2. Establish the site root directory of the virtual machine host

mkdir /var/wwwroot
mkdir /var/wwwroot/site1
mkdir /var/wwwroot/site2
echo -e "site1" >> /var/wwwroot/site1/index.html
echo -e "site2" >> /var/wwwroot/site2/index.html

3. Turn off the centos firewall

setenforce 0
systemctl stop firewalld
systemctl disable firewalld

  index index.html;

  location / {
  }
}
server {
 listen 8082;
 root /var/wwwroot/site2;
 index index.html;

 location / {
 }
}

3. Start the nginx service
