Not yet familiar with the Linux system installation Haproxy record!

Recently the company's IIS server is always down, their knowledge of operation and maintenance is very short, listen to some of the introduction decided to bite the bullet, set up a haproxy load to the back end of two IIS. Here's a summary of experience!

First install haproxy with yum command This is very simple, say the process! Install the GCC compiler first

# yum Install gcc

# wget http://haproxy.1wt.eu/download/1.4/src/haproxy-1.4.24.tar.gz

# tar ZXVF haproxy-1.4.24

# make Install

# mkdir-p/usr/local/haproxy/etc

# mkdir-p/usr/local/haproxy/sbin

# CP Examples/haproxy.cfg/usr/local/haproxy/etc

# ln-s/usr/local/sbin/haproxy/usr/local/haproxy/sbin/haproxy

To install the steps here are basically completed, the following start to make configuration file modification, found on the Internet a lot of files to try unsuccessfully, finally found a blog post with an ACL configuration success, and do not understand the specific meaning. Let's do it with your own understanding!
