Record the process of compiling haproxy 1.8.9 under Ubuntu.

According to the README instructions of HAproxy, first compile the non-shared independent function library for haproxy to use.
Since I have already installed and compiled it, I will start with the compilation of OpneSSL.

Compile OpenSSL for HAproxy to use:

At the time of this article, the latest version of openssl I downloaded is 1.0.2o

wget https://www.openssl.org/source/openssl-1.0.2o.tar.gz

After decompression, enter the openssl-1.0.2 directory,

tar zxvf openssl-1.0.2o.tar.gz
cd haproxy-1.8.9/

Execute configuration and compilation:

export STATICLIBSSL=/tmp/staticlibssl
./config --prefix=$STATICLIBSSL no-shared
make && make install_sw

If there is an error in ./config configuration, #include "pcre.h"
The relevant dev library is missing. My method is to search and find it before installing:
Ubuntu:

apt-cache search libpcre
apt-get install libpcre3-dev

CentOS is:

sudo yum install pcre-devel

After the installation is complete, re-execute config and make

Compile HAProxy

The HAProxy I downloaded in this article is the latest version of 1.8.9:

wget http://www.haproxy.org/download/1.8/src/haproxy-1.8.9.tar.gz

unzip

 tar zxvf haproxy-1.8.9.tar.gz

Enter

cd haproxy-1.8.9/

compile
Because the Linux Kernel used is greater than 2.6.28 (uname -a view)
To compile HAProxy, use the following command.

make TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1

Everything goes smoothly, you can install the haproxy command into the system.

make install
