Apache Traffic Server
Traffic Server is a high-performance building block for cloud services.
It's more than just a caching proxy server; it also has support for
plugins to build large scale web applications.

2. REQUIREMENTS
This section outlines build requirements for different OS
distributions. This may be out of date compared to the on-line
requirements at
<https://cwiki.apache.org/confluence/display/TS/Building>.
As of ATS v7.0.0 and later, gcc 4.8.1 or later is required, since we now use
and require the C++11 standard.
Fedora / CentOS / RHEL:
autoconf
automake
libtool
pkgconfig
perl-ExtUtils-MakeMaker
gcc/g++ or clang/clang++
openssl-devel
tcl-devel
pcre-devel
ncurses-devel and libcurl-devel(optional, needed for traffic_top)
libcap-devel (optional, highly recommended)
hwloc-devel (optional, highly recommended)
flex (optional, needed for e.g. WCCP)
Ubuntu / Debian
autoconf
automake
libtool
pkg-config
libmodule-install-perl
gcc/g++ or clang/clang++
libssl-dev
tcl-dev
libpcre3-dev
libcap-dev (optional, highly recommended)
libhwloc-dev (optional, highly recommended)
libncurses5-dev (optional, required for e.g.: traffic_top)
libcurl4-openssl-dev (optional, required for e.g.: traffic_top)
flex (optional, required for e.g. WCCP)
Alpine Linux

tcl-tk (or tcl from Homebrew-Cask)
openssl
pcre
FreeBSD
devel/gmake
devel/autoconf
devel/automake
devel/pkgconf
devel/libtool
lang/tcl85
security/openssl
devel/pcre
textproc/flex (optional, install newer version from ports, fix PATH)

developer/build/libtool
omniti/runtime/tcl-8
library/security/openssl
library/pcre
3. Building from distribution
You can download the latest source code from the official Apache Traffic
Server site:
http://trafficserver.apache.org/downloads
(or via the URL shortener: http://s.apache.org/uG). Once downloaded,
follow the instructions:
tar xf trafficserver-2.1.8-unstable.tar.bz2
cd trafficserver-2.1.8-unstable
./configure # configure the build environment to create Makefiles
make # execute the compile
This will build with a destination prefix of /usr/local. You can finish
the installation with
sudo make install
4. BUILDING FROM GIT REPO
mkdir -p ~/dev # make yourself a development dir
cd ~/dev # enter your development dir
git clone ... # get the source code from ASF Git repository
cd trafficserver # enter the checkout directory
autoreconf -if # generate the configure script and Makefile.in files
./configure # configure the build environment to create Makefiles
make # execute the compile
4b. Instructions for building on EC2
NOTE: Alternately you may use the scripts under 'contrib' which will
automate the install for trafficserver under EC2 which is
HIGHLY RECOMMENDED. See 'README-EC2' for further details.
# As root do the following when using Ubuntu
mkdir -p /mnt #EC2 Storage Mount, where storage is located
cd /mnt
git clone ... # get the source code from ASF Git repo
cd trafficserver # enter the checkout dir
autoreconf -i --force # generate the configure script and Makefile.in files
./configure
make
# As root do the following when using Fedora Core 8 kernel
mkdir -p /mnt #EC2 Storage Mount, where storage is located
cd /mnt
git clone ... # get the source code from ASF Git repo
cd trafficserver # enter the checkout dir
autoreconf -i --force # generate the configure script and Makefile.in files
./configure --disable-eventfd
make
4c. Instructions for building on FreeBSD
The only difference is how to run configure and make:
MAKE=gmake ./configure # make sure that gmake is the make we use
gmake
5. INSTALLATION
DEFAULT DIR CONTENTS
/usr/local/var/log/trafficserver log files created at runtime
/usr/local/var/trafficserver runtime files
/usr/local/etc/trafficserver configuration files
/usr/local/bin executable binaries
/usr/local/libexec/trafficserver plugins
6. CRYPTO NOTICE
