This article is to share with you how to install haproxy in centos or Ubuntu. I believe most people don't know how to install it yet. In order to let you learn, I summarized the following contents. Without saying much, let's read on.

Root@ubuntu:~# add-apt-repository ppa:vbernat/haproxy-2.0 HAProxy is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for web sites crawling under very high loads while needing persistence or Layer7 processing. Supporting tens of thousands of connections is clearly realistic with todays hardware. Its mode of operation makes its integration into existing architectures very easy and riskless, while still offering the possibility not to expose fragile web servers to the Net.This PPA contains packages for HAProxy 2.0.

# start haproxy

Centos7.6 Yum installation 1.8.14

By default, the packages in centos7 are older. Haproxy is 1.5.18-9.el7, which does not meet the requirements. In this case, we can install it based on the third-party installation package yum.

Https://pkgs.org/download/haproxy the URL el7 updated the latest rpm package to 1.8.14

Generally, you need an installation package that relies on the repository package and haproxy.rpm

Download the installation package

Wget https://centos.pkgs.org/7/cheese-x86_64/haproxy-1.8.14-1.el7.x86_64.rpm.html

Download dependency package

Weget https://centos.pkgs.org/7/cheese-x86_64/cheese-release-7-1.noarch.rpm.html

Install the corresponding package

# rpm-ivh cheese-release-7-1.noarch.rpm#yum install haproxy-1.8.14-1.el7.x86_64.rpm-y

# verify the haproxy version

# haproxy-vHA-Proxy version 1.8.14-52e4d43 2018/09/20Copyright 2000-2018 Willy Tarreau

Centos7.6 compilation and installation of haproxy2.0.12

Compile and install HAProxy 2.0 LTS version. Download more source code packages on the official website: http://www.haproxy.org/download/

HAProxy supports functional extension based on lua and provides flexible extension and customization functions for applications. Since the lower version of lua that comes with centos does not meet the requirements of the minimum version of lua required by HAProxy, the package needs to be installed at compile time, and the official download address of lua
