Building MariaDB MaxScale from Source Code
MariaDB MaxScale can be built on any system that meets the requirements. The main requirements are as follows:
- CMake version 2.8 or later (Packaging requires version 2.8.12 or later)
- GCC version 4.4.7 or later
- SQLite3 version 3.3 or later
- Bison 2.7 or later
- Flex 2.5.35 or later
This installs MaxScale as if it was installed from a package.
sudo yum install git gcc gcc-c++ ncurses-devel bison flex glibc-devel cmake \ libgcc perl make libtool openssl openssl-devel pcre-devel \ tcl tcl-devel systemtap-sdt-devel libuuid libuuid-devel sqlite sqlite-devel \ gnutls-devel libgcrypt-devel
sudo apt-get update sudo apt-get install git build-essential libssl-dev ncurses-dev bison flex \ cmake perl libtool libpcre3-dev tcl tcl-dev uuid \ uuid-dev libsqlite3-dev gnutls-dev libgcrypt20-dev
Build and Install MaxScale
git clone https://github.com/mariadb-corporation/MaxScale mkdir build cd build cmake ../MaxScale -DCMAKE_INSTALL_PREFIX=/usr make sudo make install sudo ./postinst
Required packages on CentOS/RHEL systems
The following packages are required on CentOS/RHEL 7. Older releases may require other packages in addition to these.
git gcc gcc-c++ ncurses-devel bison flex glibc-devel cmake libgcc perl make \ libtool openssl openssl-devel pcre-devel tcl tcl-devel \ systemtap-sdt-devel libuuid libuuid-devel sqlite sqlite-devel gnutls-devel libgcrypt-devel
Required packages on Ubuntu and Debian systems
The following packages are required on Ubuntu 16.04. Different releases may require other packages in addition to these.
git build-essential libssl-dev ncurses-dev bison flex cmake perl libtool \ libpcre3-dev tlc tcl-dev uuid uuid-dev sqlite3-dev libgnutls30 libgcrypt20
Preparing the MariaDB MaxScale build
Clone the MariaDB MaxScale repository from GitHub.
git clone https://github.com/mariadb-corporation/MaxScale
Create a separate build directory where you can safely build MariaDB MaxScale without altering the source code. Change the working directory to the directory we just created.
mkdir build cd build
Configuring the build
The next step is to configure MariaDB MaxScale. You only need to execute the following command to configure the build.
cmake ../MaxScale -DBUILD_TESTS=Y
This will install MariaDB MaxScale into
/usr/local/ and build the tests. The tests and
other parts of the installation can be controlled via CMake arguments.
Here is a small table with the names of the most common parameters and what
they control. These should all be given as parameters to the -D switch in
NAME=VALUE format (e.g.
|CMAKE_INSTALL_PREFIX||Location where MariaDB MaxScale will be installed to. Set this to
|WITH_SCRIPTS||Install systemd and init.d scripts|
|PACKAGE||Enable building of packages|
|TARGET_COMPONENT||Which component to install, default is the 'core' package. Other targets are 'experimental', which installs experimental packages, 'devel' which installs development headers and 'all' which installs all components.|
|TARBALL||Build tar.gz packages, requires PACKAGE=Y|
Note: You can look into defaults.cmake for a list of the CMake variables.
Building MariaDB MaxScale
Once the configuration is complete, you can compile, test and install MariaDB MaxScale.
make make test sudo make install
Other useful targets for Make are
documentation, which generates the Doxygen documentation,
uninstall which uninstall MariaDB MaxScale binaries after an install.
Note: If you configure CMake multiple times, it's possible that you will run into problems when building MaxScale. Most of the time this manifests as a missing pcre2.h header file. When this happens, delete everything in the build directory and run the CMake command again.
Building MariaDB MaxScale packages
In addition to the packages needed to build MariaDB MaxScale, you will need the packaging libraries for your system and CMake version 2.8.12 or later.
sudo yum install rpm-build
Ubuntu and Debian systems
sudo apt-get install dpkg-dev
Next step is to clone the MariaDB MaxScale repository from GitHub. If you already cloned it when building MariaDB MaxScale, this step can be skipped.
git clone https://github.com/mariadb-corporation/MaxScale
Create a packaging directory and change the working directory to the directory we just created.
mkdir packaging cd packaging
Configure the build, giving it the same arguments we gave in the previous
section with a few changes. The only new thing is the
which allows us to build packages. The
-DCMAKE_INSTALL_PREFIX was removed since
we aren't installing MariaDB MaxScale, only packaging it.
cmake ../MaxScale -DPACKAGE=Y
Next step is to build the package.
make make package
This will create a RPM/DEB package.
To build a tarball, add
-DTARBALL=Y to the cmake invokation. This will create
a maxscale-x.y.z.tar.gz file where x.y.z is the version number.
Some Debian and Ubuntu systems suffer from a bug where
make package fails
with errors from dpkg-shlibdeps. This can be fixed by running
make package and adding the path to the libmaxscale-common.so library to
the LD_LIBRARY_PATH environment variable.
make LD_LIBRARY_PATH=$PWD/server/core/ make package
Installing optional components
MaxScale is split into multiple components. The main component is the core MaxScale package which contains MaxScale and all the modules. This is the default component that is build, installed and packaged. There exist two other components, the experimental and the devel components. The former contains all experimental modules which are not considered as part of the core MaxScale package and they can be alpha or beta quality modules. The latter of the optional components, devel, contains the development files required for MaxScale module development.
The component which is build is controlled by the TARGET_COMPONENT CMake variable. The default value for this is core which builds the core MaxScale package.
To build other components, you will need to set value of the TARGET_COMPONENT CMake variable to the component name you wish to install or package.
Install experimental modules
To install the experimental modules, invoke CMake with -DTARGET_COMPONENT=experimental:
cmake ../MaxScale -DTARGET_COMPONENT=experimental make make install
Creating a monolithic package
To create a monolithic package with all the components, set the value of TARGET_COMPONENT to 'all', PACKAGE to Y and build the package:
cmake ../MaxScale -DPACKAGE=Y -DTARGET_COMPONENT=all make package
