HAproxy + Keepalive implement LDAP proxy service
Because the company has a lot of self-developed systems, all of these systems are using LDAP for authentication. Currently, we have several DC controllers to share these ldap requests, the user accesses the domain name ldap.xxxx.com to connect to the ldap server. We direct the domain name to different DC servers through DNS round robin.
The following problem occurs: When a DC fails, authentication may
Haproxy-1.5.x SSL Configuration
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.

Haproxy provides high availability, load balancing, and proxies based on TCP and HTTP applications, supporting virtual hosting, which is a free, fast, and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing. The haproxy runs on the current hardware and can support tens of t
These days I compare nginx and Haproxy, and come to a surprising result.First, some background information is presented. For a long time, we bengler the Nginx as the main Web server for our project, just as we did under mongrel as a proxy for rails. Nginx is a very good small open source software, it occupies a small space, a reasonable configuration language, advanced features and fast. However, we quickly discovered that the load balancing feature o

1.HAProxy Introduction
Haproxy is an open-source, high-performance, load-balancing software based on TCP (four-tier), HTTP (seven-tier) applications. That haproxy as a professional load balancer software, it has the following advantages:
Very good reliability and stability, comparable to hardware-level F5 load balancing devices

-based scale-out solution has a lot of good performance and reputation for nginx, and the application request router directly supported by IIS Microsoft on Windows is quite good, in bingocc, you can also directly place an order to order HTTP's elastic support for load balancing. However, the customer's requirements are unlimited. In the past two days, the customer hoped that we could support both HTTP and TCP load balancing, because the customer had a message PUSH Service developed based on the
Haproxy Introduction: 1, HAProxy is a high availability, Load balancing, as well as proxy software based on TCP (layer fourth) and HTTP (seventh tier) applications, supports virtual hosting, which is a free, fast and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing.
Haproxy Introduction:Haproxy provides high availability, load balancing, and proxies based on TCP (layer fourth) and HTTP (layer seventh) applications, supporting virtual hosts;Haproxy is especially useful for web sites that are particularly heavily loaded, and often require session-hold or seven-tier processing. Haproxy runs on today's hardware, fully supports t
Software load Balancing is generally implemented in two ways: the implementation of soft load based on operating system and the implementation of soft load based on third party application. LVS is a kind of soft load based on Linux operating system, Haproxy is an open source and soft load based on the third application implementation.Haproxy compared to the use of LVS is much simpler, the function is also very rich.
