YottaDB

All software in this package is part of YottaDB (http://yottadb.com) each file of which identifies its copyright holders. The software is made available to you under the terms of a license. Refer to the LICENSE file for details.

YottaDB relies on CMake to generate the Makefiles to build binaries from source. The prerequisites are CMake (at least 2.8.5), GNU make (at least 3.81), Linux (x86_64), libraries and development files for libz, Unicode, OpenSSL and GPG. Ubuntu 16.04 LTS was used to test the builds for this distribution, with default versions of packages from the distribution repositories.

How to build

1. Fulfill the prerequisites

   Install development libraries

    Ubuntu Linux OR Raspbian Linux OR Beagleboard Debian
    sudo aptitude install cmake tcsh {libconfig,libelf,libgcrypt,libgpg-error,libgpgme11,libicu,libncurses,libssl,zlib1g}-dev
   
    Arch Linux
    sudo pacman -S cmake tcsh {libconfig,libelf,libgcrypt,libgpg-error,gpgme,icu,ncurses,openssl,zlib}
   
    CentOS Linux OR RedHat Linux
    sudo yum install git gcc cmake tcsh {libconfig,gpgme,libicu,libgpg-error,libgcrypt,ncurses,openssl,zlib,elfutils-libelf}-devel

   There may be other library dependencies or the packages may have different names. If CMake issues a NOTFOUND error, please see the FAQ below.

2. Unpack the YottaDB sources

   The YottaDB source tarball extracts to a directory with the version number in the name, i.e. yottadb_r122

   $ tar xfz yottadb_r122_src.tar.gz
   $ cd yottadb_r122_src

   You should find this README, LICENSE, COPYING and CMakeLists.txt file and sr_* source directories.

3. Build the YottaDB binaries

   $ mkdir build
   $ cd build

   By default the script creates production (pro) builds of YottaDB. To create a debug (dbg) build of YottaDB supply the following parameter to cmake -D CMAKE_BUILD_TYPE=Debug Note: title case is important

   $ cmake -D CMAKE_INSTALL_PREFIX:PATH=$PWD ../
   $ make -j `grep -c ^processor /proc/cpuinfo`
   $ make install
   $ cd yottadb_r122

Note that the make install done above does not create the final installed YottaDB. Instead, it stages YottaDB for distribution.

Now you are ready to install YottaDB. The default installation path is /usr/local/lib/yottadb/r122 but can be controlled using the --installdir option. Run ./ydbinstall --help for a list of options.

$ sudo ./ydbinstall
$ cd - ; make clean

4. Packaging YottaDB

   Create a tar file from the installed directory

Docker

Pre-requisites

A working Docker installation on the platform of choice.

NOTE: You must have at least docker 17.05 as multi-stage builds are used within the docker file

Image information

The docker image is built using the generic ydb script that gives the user some sane defaults to begin exploring YottaDB. This isn't meant for production usage.

The commands below assume that you want to remove the docker container after running the command, which means that if you don't mount a volume that contains your database and routines they will be lost. If you want the container to persist remove the --rm parameter from the docker command.

Volumes are also supported by mounting to the /data directory. If you want to mount the local directory ydb-data into the container to save your database and routines locally and use them in the container in the future, add the following command line parameter before the yottadb/yottadb argument:

-v `pwd`/ydb-data:/data

This creates a ydb-data directory in your current working directory. This can be deleted after the container is shutdown/removed if you want to remove all data created in the YottaDB container (such as your database and routines).

Pre-built images

Pre-built images are available on docker hub

Running a Pre-built image

```
docker run --rm -it yottadb/yottadb # you can add a specific version after a ":" if desired
```

Build Steps

1. Build the image

   docker build -t yottadb/yottadb:latest .
   

2. Run the created image

   docker run --rm -it yottadb/yottadb:latest
   

FAQ

• The CMake build fails with the following message followed by one or more cases. CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: This indicates that required libraries are not found. Please consult the list of libraries and check your distributions package manager.
