Cento7+nginx reverse proxy for multi-domain jump

Recently busy, so rarely write documents, recently there is a project group has a number of environments need to do mapping, so think of through nginx reverse proxy to achieve multi-domain address jump, so that summed up a bit, in fact, we all know the agent. The most common and often said is NAT, that is, the internal multiple address requests through the proxy to reach the outside. This is called the forward proxy, what is the reverse proxy-is the opposite of the forward proxy; So very good understanding, Nginx Reverse proxy function is very powerful, can be implemented through an Nginx proxy multiple domain names and different ports for proxy forwarding, so in the daily operation dimension is very helpful. Our demo today is to implement a different internal forwarding of multiple domains via Nginx reverse proxy. specifically see below:

Environment:

Hostname:a-s.ixmsoft.com

ip:192.168.5.21

Role:nginx Service

Hostname:b-s.ixmsoft.com

ip:192.168.5.22

Role:nginx Service

Hostname:d-s.ixmsoft.com

ip:192.168.5.20

Role:nginx Reverse Proxy

Requirements: By configuring Nginx reverse proxy to access different domain names to achieve the jump.

The Web services provided by our two in-house testing Nginx have been installed.

We need to edit the display on the default Nginx default display page:

Vim/usr/share/nginx/html/index.html

<! DOCTYPE Html>
192.168.5.21
650) this.width=650; "title=" image "style=" border-top:0px;border-right:0px;background-image:none;border-bottom:0 px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt=" image "src=" Http://s3.51cto.com/wyfs02/M01/8B/5B/wKioL1hKjoaz2NxaAABbnFvDJXY670.png "height=" 365 "/>
192.168.5.22
650) this.width=650; "title=" image "style=" border-top:0px;border-right:0px;background-image:none;border-bottom:0 px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt=" image "src=" Http://s3.51cto.com/wyfs02/M02/8B/5E/wKiom1hKjofDx-JwAABdgg8eDLg473.png "height=" 365 "/>
Then we start to install and configure the Nginx reverse proxy;
We first install Nginx, because it is Centos7, so we need to install Nginx warehouse.
Yum Install Http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpmyum Install Nginx
650) this.width=650; "title=" clip_image001[6] "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt = "Clip_image001[6]" src= "http://s3.51cto.com/wyfs02/M02/8B/5B/wKioL1hKjoijk9_QAADG6aHntJY442.png" height= "250"/ >
650) this.width=650; "title=" clip_image001[8] "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt = "Clip_image001[8]" src= "http://s3.51cto.com/wyfs02/M00/8B/5E/wKiom1hKjonjcenKAAEcfbhdmDU723.png" height= "427"/ >
We'd better have a backup of the nginx.conf file.
Cp/etc/nginx/nginx.conf/etc/nginx/nginx.conf.bak
650) this.width=650; "title=" clip_image001[10] "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt = "clip_image001[10]" src= "Http://s3.51cto.com/wyfs02/M01/8B/5E/wKiom1hKjory00k5AAAxmCrwKO0271.png" height= "54"/ >
Then we open the default nginx.conf file
Vim/etc/nginx/nginx.conf
You can see the contents of the default nginx.conf
user nginx;worker_processes 1;error_log /var/log/nginx/ error.log warn;pid /var/run/nginx.pid;events {worker_connections 1024;} Http {include /etc/nginx/mime.types;default_type application/octet-stream;log_format main   ' $remote _addr -  $remote _user [$time _local]  "$request"   "$status   $body _ bytes_sent  "$http _referer"   "$http _user_agent"   "$http _x_forwarded_for"; access_log /var/ log/nginx/access.log main;sendfile on; #tcp_nopush  on;keepalive_timeout 65; #gzip  on; include /etc/nginx/conf.d/*.conf; 
650) this.width=650; "title=" clip_image001[12] "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt = "clip_image001[12]" src= "http://s3.51cto.com/wyfs02/M02/8B/5E/wKiom1hKjo7g8KLDAACwiTUzScY202.png" height= "341"/ >
we see the nginx default configuration includes an option to include multiple profiles, so we can generally not modify this default configuration file;
And the default configuration file, already contains the Nginx configuration file loading directory, meaning, as long as it is under the/etc/nginx/conf.d/of all the. conf files will be loaded.
In addition, we need to note that the contents of this configuration file are in the HTTP zone.
650) this.width=650; "title=" clip_image001[14] "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt = "clip_image001[14]" src= "http://s3.51cto.com/wyfs02/M00/8B/5E/wKiom1hKjo-zCgUKAADN0VfcS0g215.png" height= "370"/ >
We view the default configuration file
650) this.width=650; "title=" clip_image001[16] "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt = "clip_image001[16]" src= "Http://s3.51cto.com/wyfs02/M01/8B/5E/wKiom1hKjpGw5Q3OAAA_lYRB3Mg221.png" height= "73"/ >
We view the default default.conf file contents
Vim default.conf
650) this.width=650; "title=" clip_image001[18] "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt = "clip_image001[18]" src= "http://s3.51cto.com/wyfs02/M00/8B/5B/wKioL1hKjpHS1UDBAAFQdp29f2E467.png" height= "455"/ >
We see that this configuration file has taken up 80 ports, we will modify the 80 port, otherwise there will be conflicts, change to 88 again.
650) this.width=650; "title=" clip_image001[20] "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt = "clip_image001[20]" src= "http://s3.51cto.com/wyfs02/M01/8B/5B/wKioL1hKjpLw2J8bAADwZ29VC4E661.png" height= "378"/ >
Next we create a new configuration file to configure the reverse proxy content, of course, we can also directly in the default configuration file modification, but we generally do not modify the default configuration.
Vim realy-proxy.conf
Then add the server address information
server {listen 80;server_name localhost;location /  {root html;index index.html index.htm;} error_page 500 502 503 504 /50x.html;location = /50x.html {root  html;}} Server{listen 80;server_name d1.ixmsoft.com;location / {proxy_redirect off;proxy_set_ header host  $host;p roxy_set_header x-real-ip  $remote _addr;proxy_set_header  x-forwarded-for  $proxy _add_x_forwarded_for;proxy_pass http://192.168.5.21:80;}} Server{listen 80;server_name d2.ixmsoft.com;location / {proxy_redirect off;proxy_set_ header host  $host;p roxy_set_header x-real-ip  $remote _addr;proxy_set_header  x-forwarded-for  $proxy _add_x_forwarded_for;proxy_pass http://192.168.5.22:80;}} 
650) this.width=650; "title=" image "style=" border-top:0px;border-right:0px;background-image:none;border-bottom:0 px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt=" image "src=" Http://s3.51cto.com/wyfs02/M02/8B/5E/wKiom1hKjpOyE4_fAABMwNp94Dc787.png "height=" 222 "/>
--------------------------------------------------------------------------------
We finally add a log file that logs the access log
We need to create a log directory under the/etc/nginx directory
Cd/etc/nginxmkdir logs
This folder has to have you start the Nginx user Write permission
650) this.width=650; "title=" clip_image001[22] "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;padding-right:0px, "border=" 0 "alt=" clip_ IMAGE001[22] "src=" Http://s3.51cto.com/wyfs02/M02/8B/5B/wKioL1hKjpTxYjsYAAGyMYXYm6g590.png "height=" 254 "/>
 and add it in the new profile 
 
server {listen 80;server_name localhost;location /  {root html;index index.html index.htm;} error_page 500 502 503 504 /50x.html;location = /50x.html {root  html;}} Server{listen 80;server_name d1.ixmsoft.com;location / {proxy_redirect off;proxy_set_ header host  $host;p roxy_set_header x-real-ip  $remote _addr;proxy_set_header  x-forwarded-for  $proxy _add_x_forwarded_for;proxy_pass http://192.168.5.21:80;} Access_log logs/d1.ixmsoft.com_access.log;} Server{listen 80;server_name d2.ixmsoft.com;location / {proxy_redirect off;proxy_set_ header host  $host;p roxy_set_header x-real-ip  $remote _addr;proxy_set_header  x-forwarded-for  $proxy _add_x_forwarded_for;proxy_pass http://192.168.5.22:80;} Access_log logs/d2.ixmsoft.com_access.log;} 
And then restart the Nginx service.
Systemctl RESTATRT Nginx
Next we test the access
We visit d1.ixmsoft.com
650) this.width=650; "title=" clip_image018 "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt = "clip_image018" src= "http://s3.51cto.com/wyfs02/M00/8B/5B/wKioL1hKjpXhgUrEAABJpU9S4Xk462.jpg" height= "248"/>
D2.ixmsoft.com
650) this.width=650; "title=" clip_image020 "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;padding-right:0px, "border=" 0 "alt=" clip_ image020 "src=" http://s3.51cto.com/wyfs02/M01/8B/5B/wKioL1hKjpby1THUAABJKojaeOQ525.jpg "height=" 243 "/>
Finally we look at log in the log directory
Cd/etc/nginx/logs
650) this.width=650; "title=" image "style=" border-top:0px;border-right:0px;background-image:none;border-bottom:0 px;padding-top:0px;padding-left:0px;border-left:0px;padding-right:0px; "border=" 0 "alt=" image "src=" http:// S3.51cto.com/wyfs02/m02/8b/5b/wkiol1hkjpfzao9gaabxoevtbvg106.png "height=" 193 "/>
We view the contents of two log files separately
Cat D1.ixmsoft.com_access.log
Cat D2.ixmsoft.com_access.log
We can see which machine is accessing the IP address that will be displayed
650) this.width=650; "title=" image "style=" border-top:0px;border-right:0px;background-image:none;border-bottom:0 px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "border=" 0 "alt=" image "src=" Http://s3.51cto.com/wyfs02/M00/8B/5E/wKiom1hKjpjzPwNHAADlCZlb-KI947.png "height="/>
