HAProxy The Reliable, High Performance TCP/HTTP Load Balancer

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 very high traffic web sites and powers quite a number of the world's most visited ones. Over the years it has become the de-facto standard opensource load balancer, is now shipped with most mainstream Linux distributions, and is often deployed by default in cloud platforms.

LUA

LUA

What is Lua? Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description.

Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode with a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping.

Your Starter Guide to Using the HAProxy Lua Event Framework

QuickStart(use quiet mode)

haproxy.exe -f haproxy.config.json -q -D
or
haproxy.exe -f haproxy.config.cfg -q -D

Usage : haproxy [-f <cfgfile>]* [ -vdVD ] [ -n <maxconn> ] [ -N <maxpconn> ]
        [ -p <pidfile> ] [ -m <max megs> ] [ -C <dir> ] [-- <cfgfile>*]
        -v displays version ; -vv shows known build options.
        -d enters debug mode ; -db only disables background mode.
        -dM[<byte>] poisons memory with <byte> (defaults to 0x50)
        -V enters verbose mode (disables quiet mode)
        -D goes daemon ; -C changes to <dir> before loading files.
        -q quiet mode : don't display messages
        -c check mode : only check config files and exit
        -n sets the maximum total # of connections (2000)
        -m limits the usable amount of memory (in MB)
        -N sets the default, per-proxy maximum # of connections (2000)
        -L set local peer name (default to hostname)
        -p writes pids of all children to this file
        -de disables epoll() usage even when available
        -dp disables poll() usage even when available
        -dS disables splice usage (broken on old kernels)
        -dV disables SSL verify on servers side
        -sf/-st [pid ]* finishes/terminates old pids.

How to build

Compilation and installation of HAProxy in Windows

1. Download and Install cygwin (https://cygwin.com/setup-x86_64.exe), after installation, copy setup-x86_64.exe to c:\cygwin64

2. On terminal (cmd), install gcc, make and libs

   lua5.3

   cd c:\cygwin64
   .\setup-x86_64.exe -q -P wget -P gcc-g++ -P make -P libssl-devel -P zlib-devel -P lua-devel -P libpcre-devel
   

   lua5.4

   cd c:\cygwin64
   .\setup-x86_64.exe -q -f -P wget -P gcc-g++ -P make -P libssl-devel -P zlib-devel -P lua-devel -P liblua-devel -P lighttpd-lua-modules -P lua -P libpcre-devel
   

3. Open the cygwin64 terminal

   Cygwin.bat
   

4. Download source code (inside cygwin64 terminal)

       wget https://www.haproxy.org/download/3.2/src/devel/haproxy-3.2-dev0.tar.gz
       tar xzvf haproxy-3.2-dev0.tar.gz
       rm -rf ./haproxy-3.2-dev0.tar.gz 
       cd haproxy-3.2-dev0
   

5. Build (inside cygwin64 terminal)

   lua5.3

   sed -i 's/--export-dynamic/--export-all-symbols/g' Makefile
   make TARGET=cygwin USE_OPENSSL=3.0 USE_ZLIB=1.3.1 USE_PCRE=1 USE_LUA=1 LUA_LIB=/usr/lib LUA_INC=/usr/include/lua5.3 LUA_LIB_NAME=lua5.3
   

   lua5.4

   sed -i 's/--export-dynamic/--export-all-symbols/g' Makefile
   make TARGET=cygwin USE_OPENSSL=3.0 USE_ZLIB=1.3.1 USE_PCRE=1 USE_LUA=1 LUA_LIB=/usr/lib LUA_INC=/usr/include/lua5.4 LUA_LIB_NAME=lua5.4
   

6. Copy haproxy.exe and all dependencies (.dll)

   # show dependencies
   dependencies=$(ldd ./haproxy.exe | awk '{print $3}')
   
   # create a folder in C:/
   mkdir -p /cygdrive/c/haproxy-3.2
   
   # copy all
   cp ./haproxy.exe /cygdrive/c/haproxy-3.2
   for dep in $dependencies; do
       cp "$dep" /cygdrive/c/haproxy-3.2
   done
   
   # delete trash
   cd ..
   rm -rf ./haproxy-3.2-dev0
   
   # exit cygwin64 terminal
   exit
   

7. On cmd, you can test haproxy

   cd C:\haproxy-3.2
   .\haproxy.exe -v 
   .\haproxy.exe -vv
