thread called Pthread_exitThere are 3 kinds of abnormal termination, they are6: Call Abort7: Received a signal and terminated8: Last thread responds to cancellation request2, Sticky bitThe Sticky bit is an access flag bit that can be used to mark files and paths. The most common usage is to set the sticky bit on the directory, so that only the owner or root of t

Introduction: The difference between LVS and HaproxyLvs:1, strong anti-load capacity, is the work in the Network 4 layer on the distribution only, no flow generation;2, no flow, to ensure that the performance of the Equalizer IO will not receive the impact of large traffic;3, the application of a wide range, because LVS work in the 4 layer, so it can almost all applications to do load balancing4, the work is stable, because of its own resistance to load capacity is very strong, self has a comple

First, what is sticky bag1. Note: Only TCP has a sticky packet phenomenon, UDP will never stick packets2. The so-called sticky packet problem is mainly because the receiver does not know the boundary between the message, do not know how many bytes of data extracted at once.Two, two kinds of cases will occur sticky bag.

Sticky bagSticky bag phenomenonAfter executing multiple commands at the same time, the resulting results are likely to be only part of the result, and when other commands are executed, another part of the result of the previous execution is received, which is the sticky packet.The implementation of sticky packets based on TCP protocolServer Side##### #server End

suid Meaning: The bit of the file is set to 1, and when the file is executed, the file will run as the owner, i.e. whoever comesExecute this file, he has the privileges of the owner of the file, if the owner is root, then the executor has SuperuserPrivilege, which is the bit that will become a security vulnerability, so do not set that bit easily.Sgid Meaning: The runner will have permissions for all groups of files.Bonding bit: Requires the operating system to retain the image of the program in

Implementation requirements:Using Haproxy To do load balancing, manually add or remove node server information in the configuration file, it is more troublesome. Collect the information that needs to be registered to Consul as the Haproxy node server through Registrator, and then register to Consul Key/value . Consul-template go to Consul key/value to read the information and then automatically modify the

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

Comparison of load balance between LVS, Haproxy and NginxFrom the performance and stability of the most bull LVs, basically reached the F5 hardware equipment 60% performance, a few other 10% are a bit difficult. But because of the LVS bull, configuration is the most troublesome, and health testing needs to be configured Ldirector, other haproxy and nginx themselves, and the configuration super simple.If the

The haproxy-1.4 version agent is always used, and SSL configuration is not supported, the haproxy-1.5 version is supported, so the version is updated for testing. You can use the original Apache SSL Certificate file for simple processing on haproyx.Originally intended to use haproxy-1.4 penetration, but to back-end servers to configure SSL, so configured on the H

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
