f5 virtual load balancer

Recently want to be able to configure load balancing, in the virtual machine above, but the Internet to find a lot of information is fragmented, for people who do not know, a lot of not enough detail, recently finally done, the specific steps to write down, convenient for you to read the studyThis experiment requires the installation of Nginx if not installed, please refer to:Linux installation nginx:http:/

Build a mysql Server Load balancer and a high-availability environment and a mysql Server Load balancer Objective: To use two hosts to achieve Mysql load balancing and redundancy, and achieve dual-master-slave mutual backup; Environment: rhel5.8, mysql-5.0.77, keepalived-1.2

======================================= F5 Full Name: F5-BIG-IP-GTM Global traffic manager. is a company called F5 Networks development of the four-seven-layer switch, hardware and software bundles. It is said to have originally used BSD systems, which are now Linux; hardware is Intel's PC architecture, plus the surrounding network and dedicated acceleration d

This somewhat counters the weaknesses of the both of the original algorithms, but does no account for when a server was about To is overloaded–like when three requests to that Query-heavy JSP has just been submitted, but not yet hit the heavy Wo RK.

Load balancer dedicated devices, which are available from many companies. The use of specialized hardware equipment provided by specialized companies is very valuable to many companies with specific requirements, such as banking, telecommunications and other industries, but hardware aging speed is too fast, feel a device has not started to use, it is going to enter the recession period. I also vaguely remem

capability. However, some data shows that most vswitches no longer have a layer-4 switching capability at such a high speed, only layer-3 or layer-2 exchange is supported. 　 However, for most sites, the current load balancing mainly solves the bottleneck of the Web server's processing capability, rather than the network transmission capability. The total Internet connection bandwidth of many sites is less than 10 MB, only a few sites can have high-sp

The key point explanation of the construction process, the key step explanation. 6. This program has been used in practical production applications for many times, and can be flexibly applied. Second, the software

requirements, in addition, line upgrades are too expensive or even difficult to implement. In this case, we can consider using the trunking technology. Link aggregation technology (Layer 2 load balancing) uses multiple physical links as a single aggregation Logical Link. network data traffic is shared by all physical links in the aggregation Logical Link, this increases the capacity of the link logically so that it can meet the demand for increased b

balancer modifies the source address while modifying the destination IP address. Set the source address of the data packet to its own disk, that is, the source address conversion (snat ). (2) use the server load balancer server as the gateway server of the real physical server cluster. Advantages: (1) data distribution in the kernel process is better than distri

is a virtual IP address of keepalived. It is an external public IP address and also an IP address pointed to by DNS. Therefore, when designing the website architecture, you must apply for an external IP address from your IDC. 11. during actual project implementation, we found that LVS and nginx have excellent support for HTTPS, especially LVS, which is easier to process. 12. During LVS + keepalived and nginx + keepalived troubleshooting, both of them

At present, the global application of a wide range of load balancing equipment for the United States F5. F5 in China in the end of 2000, in the domestic industry, F5 load balancing products have become the mainstream load balancin
