DBA morning check listby Bill Richard, 2010/08/27 (first published: 2008/04/14) Database administrators can sometimes have one of the most stressful jobs in the company. if you have been a dBA for long, you know the scenario. you have just sat in your chair with your cup of coffee, and your phone starts ringing off the hook. the voice on the other end states that they can't pull up their data or they are getting timeouts, or the system is running slow. okay, time to dig in; it 'S going to be one

First use php to obtain the ip address of the local machine, and then use the php curl function to obtain the detailed region of the user. Let's take a look at the code below; The Code is as follows: /** This function is used to obtain the client and IP address. */Function GetIP (){If (! Empty ($ _ SERVER ["HTTP_CLIENT_IP"]){$ Cip = $ _ SERVER ["HTTP_CLIENT_IP"];}Else if (! Empty ($ _ SERVER ["HTTP_X_FORWARDED_FOR"]){$

Php method for determining the access IP address. This article mainly introduces how php judges access IP addresses. it involves php's judgment and usage skills on SERVER-side predefined variable $ _ SERVER, if you need a friend, you can use php to determine how to access the IP address. This article mainly introduces php's method of determining the IP address to be accessed. it involves php's judgment and usage skills on the SERVER's predefined variable $ _ SERVER.

Detailed description of LVS Server Load balancer cluster service establishment I. LVS Overview 1. LVS: Linux Virtual Server Layer-4 Switching (Routing): forwards request packets to a server in the backend host Cluster Based on the target IP address and target PORT (based on Scheduling Algorithm ); Load Balancing at the application layer cannot be achieved Lvs (also known as ipvs) is implemented based on the firewall netfilter in the kernel. 2. lvs cluster terminology: Vs: Virtual Server

This article mainly introduces the PHP curl fake IP address and header information code example, this article gives the server and client implementation code, to provide forgery and server-side detection code, need friends can refer to the Although Curl is powerful, but can only forge $_server["Http_x_forwarded_for"], for most IP address detection program, $_server["REMOTE_ADDR" is difficult to be forged: First, it's client.php code. The code is as follows:
