Preface: We KnowTomcat+nginxLoad Balancing cluster,LVsLoad Balancing clusterAndHaproxyto build a cluster, these three clusters are comparedLVsthe performance is the best, but the building is complexNginxof theUpstreamThe module supports clustering, but there is not much fault checking on the nodes of the cluster, and no performanceHaproxyWell, so it should be saidHarpoxyis also very good. So then we started using haproxy to build the cluster. One, top

forwards data to the backend upstream server. Timeout client: timeout duration of the client's inactive status Timeout server: haproxy maintains a session with the backend server segment. When the backend server is down, haproxy waits for timeout. Timeout-keep-alive: defines the timeout duration of the connection persistence mode. Timeout-check: the timeout time for establishing status detection.

programs often have poor extensibility. That's why they have to be optimized so that each CPU time slice (Cycle) does more work.--Excerpt from Baidu EncyclopediaImplementation process diagram:The first step: install httpd, PHP and Haproxy, here we directly with Yum to install, here we use three virtual machines to do the test, the front-end of a

balancer software, which is implemented at the software level, so the cost is very low. Currently, the website architecture is generally reasonable and popular: The Web Front-end uses nginx/haproxy + keepalived as the Load balancer, And the backend uses the MySQL database for master-slave and read-write separation, use the LVS + keepalived architecture. Of course, you must develop a scheme based on the specific needs of the project.Next we will talk

Hproxy provides high availability, load balancing, and reverse proxies based on TCP and HTTP applications, especially for those web sites that are heavily loaded, which typically require session hold or seven-tier processing. Haproxy runs on the current hardware, fully supports tens of thousands of concurrent connections, and its operating mode makes it easy and secure to integrate into the architecture, while protecting your Web server from being exp

I built the Tomcat+nginx load Balancer cluster, the LVM load Balancing cluster, I'm going to get a haproxy load Balancer cluster, the three clusters I have to realize the LVS performance is really good (DR) but in the construction process is too cumbersome, Nginx is the use of upstream module cluster but the cluster node failure check function is not enough performance and LVM is a bit far away, so today to a middle person haproxy.One , build

Recently the company's IIS server is always down, their knowledge of operation and maintenance is very short, listen to some of the introduction decided to bite the bullet, set up a haproxy load to the back end of two IIS. Here's a summary of experience!First install haproxy with yum command This is very simple, say the process!
