Nginx is used as the basic application of web servers

Nginx has unmatched performance in apache for static web pages, so the following describes the functions of nginx from the shortest to the deep: 1. Compile and install nginx1. initialize environment variables: # yumgroupinstall & quot; DevelopmentLibraries & quot; # yuminstallgccopens...

As nginx has unmatched performance in apache when doing static web pages, The following describes the role of nginx from the shortest to the deep:
1. Compile and install nginx
1. initialize environment variables:
# Yum groupinstall "Development Libraries"
# Yum install gcc openssl-devel pcre-devel zlib-devel
2. Compile and install nginx
# Tar xf nginx-1.1.3.tar.gz
# Cd nginx-1.1.3

3. Compile the nginx startup script:
# Vim/etc/init. d/nginx
#! /Bin/sh
#
# Nginx-this script starts and stops the nginx daemon

# Chkconfig:-85 15

4. start the nginx service
# Service nginx start
Enter http: // 192.168.0.78 for the test, as shown in:

2. since we have mentioned that we can provide web services, we will introduce how to use nginx to access virtual hosts.
1. port-based VM access
Based on the above installation process, we know that the web page is stored in/usr/HTML, so we can use different pages index.html and test.html for testing.
The content is nginx virtual one and nginx virtual two.
Now the preparations have been completed, and the next step is to configure the/etc/nginx. conf file.
The other settings remain unchanged by default. add two servers to http {...} and specify two listening ports as follows:
Server {
Listen 8080; // different ports
Server_name localhost;
Location /{
Root html;
Index test.html;
}
}
Server {
Listen 80; // different ports
Server_name localhost;
Location /{
Root html;
Index index.html;
}
}
# Service nginx reload // reload the configuration file
Enter http: // 192.168.0.78 and http: // 192.168.0.78: 8080 in the browser, as shown in:

 

2. Virtual IP-based host access
# Vim/etc/nginx. conf
Server {
Listen 80;
Server_name 192.168.0.78; // different IP addresses
Location /{
Root html;
Index test.html;
}
}
Server {
Listen 80;
Server_name 192.168.0.83; // different IP addresses
Location /{
Root html;
Index index.html;
}
}
My Nic configuration
# Ifconfig eth0 192.168.0.78
# Ifconfig eth0: 0 192.168.0.83
Enter http: // 192.168.0.78 and http: // 192.168.0.83 in the browser, as shown in.

 

3. host name-based VM
# Vim/etc/nginx. conf
Server {
Listen 80;
Server_name node1.luowei.com; // the host name is different.
Location /{
Root html;
Index test.html;
}
}
Server {
Listen 80;
Server_name node2.luowei.com; // the host name is different.
Location /{
Root html;
Index index.html;
}
}
Enter the http://node1.luowei.com and http://node2.luowei.com in the browser to test, as shown in

 

The experiment is complete and there is a certificate to be continued...
