Use Nginx for reverse proxy (Configure virtual Host)

Requirements: Use a different domain name. Access the same IP, get to a different port server

(Linux server)

1. Installation of Nginx required environment (may be installed)

Nginx is a C language development, it is recommended to run on Linux , this tutorial uses Centos6.5 as the installation environment. Gcc installation nginx need to download the source code to compile, compile dependent gcc environment, if there is no gcc environment, need to install Yum Install gcc-c++ PCRE PCRE (perlcompatible Regular Expressions) is a Perl library that includes a Perl- compatible regular expression library. the nginx http module uses pcre to parse the regular expression, so the Pcre library needs to be installed on Linux . Yuminstall-y Pcre Pcre-devel Note:pcre-devel is a two-time development library developed using PCRE. Nginx also needs this library. Zlib Zlib Library provides a number of ways to compressand decompress, Nginx uses zlib to gzip the contents of the HTTP packet , so it needs to be installed on Linux zlib Library. Yuminstall-y zlib Zlib-devel Openssl OpenSSL is a strong Secure Sockets Layer cipher library that includes key cryptographic algorithms, common key and certificate encapsulation management functions , and SSL protocols, and provides a rich set of applications for testing or other purposes. Nginx not only supports the HTTP protocol, but also supports HTTPS(that is , it transmits HTTP on the SSL protocol ), so it needs to be installed in Linux OpenSSL Library. Yuminstall-y OpenSSL Openssl-devel

2. Upload Nginx for decompression

tar-zxvf nginx-1.8.0.tar.gz

3. Go to unzip directory

CD nginx-1.8.0.tar.gz

4. Execute the following command to place the compiled post

The parameters are set as follows:

./configure \

--prefix=/usr/local/nginx \

--pid-path=/var/run/nginx/nginx.pid \

--lock-path=/var/lock/nginx.lock \

--error-log-path=/var/log/nginx/error.log \

--http-log-path=/var/log/nginx/access.log \

--with-http_gzip_static_module \

--http-client-body-temp-path=/var/temp/nginx/client\

--http-proxy-temp-path=/var/temp/nginx/proxy\

--http-fastcgi-temp-path=/var/temp/nginx/fastcgi\

--http-uwsgi-temp-path=/var/temp/nginx/uwsgi\

--http-scgi-temp-path=/var/temp/nginx/scgi

Note: The temp file directory above is specified as /var/temp/nginx , need to be in/var under Create temp and nginx Catalogue

5. Create/var/temp/nginx

mkdir-p/var/temp/nginx

6. Compiling the installation

Make

Make install

7. View the directory after successful installation

cd/usr/local/nginx/

ll

8. Start Nginx

cd/usr/local/nginx/sbin/

./nginx

9. View Nginx process, query whether to start

Ps-aux | grep nginx

10. Stop Nginx

mode 1, Quick stop:

Cd/usr/local/nginx/sbin

./nginx-s Stop

This method is equivalent to identifying the nginx process ID and then using the Kill command to force the kill process.

mode 2, complete stop ( recommended ):

Cd/usr/local/nginx/sbin

./nginx-s quit

This stop step is to wait until the Nginx process finishes processing the task to stop.

11. After modifying the configuration file, do not need to close, restart directly

when the nginx configuration file nginx.conf Modified, for the configuration to take effect need to restart nginx, use- s reload do not first stop Nginx re-start nginx can be configured in Nginx to take effect, as follows:

./nginx-s Reload

12. Test Installation Success

Demand:

Two domains point to the same server, and users visit different domain names to display different page content.

two domains are aaa.test.com and bbb.test.com

A server also uses virtual machine 192.168.101.3 instead

Configuration of the virtual host:

to modify the/usr/local/nginx/conf/nginx.conf file, add two virtual hosts as follows: # Configure virtual host aaa.test.com server { # Listen for IP and ports, configure native IP and Ports Listen 192.168.101.3:80; # The virtual host name is aaa.test.com and the URL of the requesting domain name aaa.test.com will be resolved by this server configuration server_name aaa.test.com; # all requests begin with / start, all requests can match this location Location/{ # Use the root command to specify the virtual host directory as the web hosting directory # For example, visit http://ip/test.html will find /usr/local/aaa_html/test.html # For example, visit http://ip/item/test.html will find /usr/local/aaa_html/item/test.html root/usr/local/aaa_html; # Specify Welcome page, search left-to-right order Index index.html index.htm; } } # Configure virtual host bbb.test.com server { Listen 192.168.101.3:80; server_name bbb.test.com; Location/{ root/usr/local/bbb_html; Index index.html index.htm; } }
