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.
AS of version 10, ATS has transitioned to cmake as its build system. Below is a quick-start guide to building ATS with cmake:
With cmake, you definitely want to create an out-of-source build. You will give that directory to every cmake command. For these examples, it will just be build.
$ cmake -B build
This will configure the project with defaults.
If you want to customize the build, you can pass values for variables on the command line. Or, you can interactively change them using the ccmake program.
$ cmake -B build -DCMAKE_INSTALL_PREFIX=/tmp/ats -DBUILD_EXPERIMENTAL_PLUGINS=ON
-- or --
$ ccmake build
To specify the location of a dependency (like --with-* for autotools builds), you generally set a variable with the ROOT. The big exception to this is for openssl. This variable is called OPENSSL_ROOT_DIR
$ cmake -B build -Djemalloc_ROOT=/opt/jemalloc -DPCRE_ROOT=/opt/edge -DOPENSSL_ROOT_DIR=/opt/boringssl
cmake has a feature for grouping configurations together to make configuration and reproduction easier. The file CMakePresets.json declares presets that you can use from the command line. You can provide your own CMakeUserPresets.json and further refine those via inheritance:
$ cmake --preset dev
You can start out your user presets by just copying CMakePresets.json and removing everything in configurePresets
Here is an example user preset:
{
"name": "clang",
"hidden": true,
"environment": {
"LDFLAGS": "-L/opt/homebrew/opt/llvm/lib -L/opt/homebrew/opt/llvm/lib/c++ -Wl,-rpath,/opt/homebrew/opt/llvm/lib/c++ -fuse-ld=/opt/homebrew/opt/llvm/bin/ld64.lld",
"CPPFLAGS": "-I/opt/homebrew/opt/llvm/include",
"CXXFLAGS": "-stdlib=libc++",
"CC": "/opt/homebrew/opt/llvm/bin/clang",
"CXX": "/opt/homebrew/opt/llvm/bin/clang++"
}
},
{
"name": "mydev",
"displayName": "my development",
"description": "My Development Presets",
"binaryDir": "${sourceDir}/build-dev-clang",
"inherits": ["clang", "dev"],
"cacheVariables": {
"CMAKE_INSTALL_PREFIX": "/opt/ats-cmake",
"jemalloc_ROOT": "/opt/homebrew",
"ENABLE_LUAJIT": false,
"ENABLE_JEMALLOC": true,
"ENABLE_MIMALLOC": false,
"ENABLE_MALLOC_ALLOCATOR": true,
"BUILD_EXPERIMENTAL_PLUGINS": true,
"BUILD_REGRESSION_TESTING": true
}
},
And then use it like:
cmake --preset mydev
$ cmake --build build
$ cmake --build build -t traffic_server
$ cd build
$ ctest
$ cmake --install build

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 v9.0.0 and later, gcc 7 or later is required, since we now use and require the C++17 standard.
cmake
ninja
pkgconfig
gcc/g++ or clang/clang++
openssl-devel
pcre-devel
ncurses-devel and libcurl-devel(optional, needed for traffic_top)
libcap-devel (optional, highly recommended)
hwloc-devel (optional, highly recommended)
cmake
ninja
pkg-config
gcc/g++ or clang/clang++
zlib1g-dev
libssl-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)

You can download the latest source code from the official Apache Traffic Server site:
https://trafficserver.apache.org/downloads
(or via the URL shortener: http://s.apache.org/uG). Once downloaded, follow the instructions:
tar jxvf trafficserver-9.1.3.tar.bz2
cd trafficserver-9.1.3
cmake -B build
cmake --build build
This will build with a destination prefix of /usr/local. You can finish the installation with
sudo cmake --install build
git clone https://github.com/apache/trafficserver.git # get the source code from ASF Git repository
cd trafficserver # enter the checkout directory
cmake --preset default # configure the build
cmake --build build-default # execute the compile
cmake --build build-default -t test # run tests (optional)
cmake --install build-default # install
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.
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
cmake --preset default # configure the build
cmake --build build-default # execute the compile
cmake --build build-default -t test
cmake --install build-default
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
cmake --preset default # configure the build
cmake --build build-default # execute the compile
cmake --build build-default -t test # run tests (optional)
