There are more than 200 personal computers and RISC workstations in China International Radio International Network Information, which speeds up network speed, reducing network traffic, through two Proxy servers, each Proxy server is half a computer (more than 100) providing proxy services . Proxy Host Running Red Flag Linux Server Edition, can support more than 200 machines within the International Radio station. However, this network structure has a big hidden danger: if a proxy server is stopped, it will lead to more than 100 computers it serve in the Internet.
There are three solutions that there are three solutions: First, all the proxy server addresses set up in more than 100 computers are changed to another proxy host, and the time-firing, which greatly increases the work burden of the system administrator. Second, use a backup proxy server to replace the original machine. However, if you usually prepare the backup server, waste; do not prepare the backup server, then temporarily configured when you fail, this more than 100 computers can not access the Internet for some time. The last method is to take over the network address of the faulty machine with another normal working proxy server. However, there are many users who have been online before the system administrator discovers the fault, check the failure and the receiving address requires the system administrator to manually operate, the same time. I must affect the work before fixing.
The HA cluster architecture solution proposed by Zhongke Hongqi provides a solution to the above problem, and the HA cluster architecture of Hongqi software provides a high availability cluster for dual or multi-machine mutual backup, making every server in the entire system. Among the mutual monitoring status, once server downtime or other phenomenon that cannot work properly, other servers can take over the network address of all its services, so that all users can work normally.
Zhongke Hongqi Software Technology Co., Ltd. is the solution provided by China International Radio Station, and the power of China's international radio station is worried about the worries of China's international radio station. In the near future, I believe that Hongqi software will have better and better solutions and cases to provide us for reference and reference.
