HAProxy "http_request_forward_body ()" Integer Overflow Vulnerability Release date:Updated on: Affected Systems:Haproxy 1.5.xDescription:CVE (CAN) ID: CVE-2014-6269 HAProxy is a TCP/HTTP Load balancer. In versions earlier than HAProxy 1.5.4, when processing the "start of value" variable in the HTTP message structure, the "http_request_forward_body ()" functio

In the development of the company, ensuring the scalability of servers plays an important role in expanding the enterprise's market. Therefore, this puts forward certain requirements for architects. Mongoiorfin, co-founder and software architect of Octivi, will introduce you to a very simple architecture. Using HAProxy, PHP, Redis, and MySQL can support 1 billion requests per week. At the same time In the development of the company, ensuring the scala

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

Because the company needs to be on-line HTTPS, so for HTTPS need to do stress testing, using the same encryption strength of the certificate, respectively, Haproxy and nginx to do stress testing, and then CPU usage comparison:The following are 1000 request stress tests for the same URL and background server:First time Haproxy 1000 times HTTPS pressure test650) this.width=650; "src=" Http://s2.51cto.com/wyfs

Let's say we have a well-configured slave , IP to be 192.168.2.15 . So now the situation is:Master1 : 192.168.2.13Master2 : 192.168.2.14VIP : 192.168.2.100Slave1 : 192.168.2.11Slave2 : 192.168.2.15Web Server: 192.168.2.11Haproxy the installation configurationdemo us

HAProxy performance in high concurrency After the xunqi message gateway server is migrated from Beijing to the Wuxi data center, after a text message is sent, only about 60% of the text message status reports are received. After understanding the business logic, you can view the statistical status on the stats page of haproxy as follows: In the red circle, we can see that the maximum number of sessions

This is my entire process of log analysis for haproxy in the unit.We have been in the maintenance ES cluster configuration, and did not put a set of processes including the collection end of the code, all their own once, and the online collection of logs when we generally use the logstash, but the industry many people say logstash whether it is performance and stability is not very good, The advantage of Logstash is the simple configuration, this time

I. haproxy HaproxyProvides high availability, Server Load balancer, and proxy Based on TCP and HTTP applications, and supports Virtual Hosts. It is a free, fast, and reliable solution.Haproxy is especially suitable for websites with extremely high loads, which usually require session persistence or layer-7 processing. Haproxy runs on the current hardware and supports tens of thousands of concurrent connecti

, often problems, rather than simple and stable. In the enterprise, more than 90% of the failure, from the demand change. It could be a bug, a human error, a schema design problem, and so on. Front-end load balancing equipment is the most important, in the software selection must be fully considered, to meet the premise of business, as far as possible to reduce complexity, improve serviceability.Project four: Implement a high-availability architecture based on

It is relatively simple to build a load-balanced high availability environment, mainly to understand the principle. This article describes the advantages and disadvantages of three load balancers, so as to be in the actual production applications, according to the requirements of choice.At present, the online environment in the application of more load Balancer hardware F5 big-ip, software has Lvs,nginx and haproxy, high availability of software heart

we typically run into a business scenario like this:b host and C database in the same intranet, a host cannot directly access the C database, we can build the agent on the B host let a access C database, we use Haproxy to do this thingCENTOS7 EnvironmentMySQL Self-installingHaproxy installation Configuration yum install-y haproxy Configuration haproxy:Vim/etc/haproxy
