HAProxy is a free, fast, and reliable proxy solution that supports high availability and server load balancer. It is also suitable for proxies for TCP and HTTP-based applications. For some websites with high load, HAProxy is particularly suitable. HAProxy supports tens of thousands of concurrent connections. It is easy to configure and can easily integrate into our existing application architecture.Next, we will install and configure HAProxy on CentOS
The current large concurrent website basically uses Nginx to do proxy server, and do cache, to carry the big concurrency. Previously also used Nginx configured a simple agent, today have time to take out the integration process and share, but most of them are also online to find resources.
Nginx The complete reverse proxy code looks like this:
[Root@data conf]# vim nginx.conf user www www.

The Apache built by RPM is suitable for most applications, it contains most of the modules, and we just use it to build a reverse proxy, too many large modules are not good, affecting performance, so we chose the targeted source code compiled, so that Apache to adapt to our platform.
Download Source code:
wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.2.25.tar.gz
Extract
Tar zxvf httpd-2.2.25.tar.gz
CD httpd-2.2.25
Prerequisites for compiling
Because the project needs to implement the function of a domain name agentLike what:
The code is as follows
Copy Code
A.com/a.html=>b.com/b.html
That is, using the a.com agent of the use of B.Com Web site request, after a friend introduction with Apache reverse agent can achieve its purpose, the man tried, really cool. It is also extremely convenient to configure.

Many people are constantly asking iptables + squid to do transparent proxy. I am afraid to give a unified answer here. If you have any questions, I hope you will give me some comments. Related Resources: man.chinaunix.net, with iptables man in the lower left corner. many people keep asking
Iptables+ Squid is used as a transparent proxy, and you are afraid to provide a unified solution here. If you have any

The previous few days, we made a function to query within the specified range on the map. Because the transmission parameter is a polygon, the number of ur points exceeds the allowed transmission standard. After the query, ESRI has already taken this issue into consideration for you.

This is the function that Nginx originally provided.
Application Scenarios

Use different ports to start different HTTP services.
Except 80 for Nginx.
Configure Nginx
sudo vim/etc/nginx/nginx.confAdd or fix to
server {Listen 80;server_name www.111cn.net;Location/{Proxy_pass http://127.0.0.1:8000;}}This way from the www.111cn.net, it will reverse proxy to 80
