Compiling MySQL Group Replication plugin with MySQL 5.7.8-rc2 on Ubuntu

MySQL Group Replication plugin is in labs.mysql.com and is available for EL6 x86_64 version Linux. But most of us have Ubuntu desktops where it should be easier to test this new thing, especially with MySQL Sandbox. After getting source code we should have compile this plugin with MySQL from source. So let’s begin. Extract both mysql group replication archive and mysql source archive:

sh@shrzayev:~/Sandboxes$ ls -l
total 650732
drwxr-xr-x 34 sh sh      4096 İyl 20 17:25 mysql-5.7.8-rc
-rw-rw-r--  1 sh sh  49762480 Avq 20 16:19 mysql-5.7.8-rc.tar.gz
drwxrwxr-x  3 sh sh      4096 Sen 28 12:08 mysql-group-replication-0.5.0-dmr
-rw-rw-r--  1 sh sh    251687 Sen 28 11:57 mysql-group-replication-0.5.0-labs.tar.gz

You will have 2 directories as above. Then, go to mysql-group-replication folder:

sh@shrzayev:~/Sandboxes$ cd mysql-group-replication-0.5.0-dmr/
sh@shrzayev:~/Sandboxes/mysql-group-replication-0.5.0-dmr$ mkdir BIN
sh@shrzayev:~/Sandboxes/mysql-group-replication-0.5.0-dmr$ cd BIN

Inside BIN folder:

> NOTE: there must be no spaces beetween cmake options(between ";")

You can run following cmake command:

cmake ..  -DMYSQL_SERVER_SRC_DIR="/home/sh/Sandboxes/mysql-5.7.8-rc" -DMYSQL_SERVER_CMAKE_ARGS="-DMYSQL_DATADIR=/opt/mysql-5.7.8-grouprepl/datadir;-DSYSCONFDIR=/opt/mysql-5.7.8-grouprepl;-DWITH_SSL=system;-DMYSQL_TCP_PORT=3307;-DMYSQL_UNIX_ADDR=/opt/mysql-5.7.8-grouprepl/mysqld.sock;-DDEFAULT_CHARSET=utf8;-DDEFAULT_COLLATION=utf8_general_ci;-DWITH_DEBUG=1;-DCOMPILATION_COMMENT='Group Replication enabled MySQL-5.7.8';-DOPTIMIZER_TRACE=1;-DWITH_ZLIB=system;-DWITH_VALGRIND=1;-DCMAKE_C_FLAGS=-DHAVE_purify;-DCMAKE_CXX_FLAGS=-DHAVE_purify;-DDOWNLOAD_BOOST=1;-DWITH_BOOST=/home/sh/Sandboxes"

But before running this command you must install corosync and related packages, if not, you will have success with compilation but will get an empty binary package For further reading refer to related BUG report -> #78600

So install dependencies:

sudo apt-get install corosync corosync-dev libcpg-dev

Then run cmake command above and after sucessful cmake run:

make package

If you list BIN folder:

sh@shrzayev:~/Sandboxes/mysql-group-replication-0.5.0-dmr/BIN$ ls
BUILD           CMakeFiles           CPackConfig.cmake  CPackSourceConfig.cmake  mysql-group-replication-0.5.0-dmr-amd64.tar.gz  SOURCE
CMakeCache.txt  cmake_install.cmake  _CPack_Packages    Makefile                 mysql_server-prefix

You will notice that there is, mysql-group-replication-0.5.0-dmr-amd64.tar.gz package where is group_replication.so file located:

sh@shrzayev:~/Sandboxes/mysql-group-replication-0.5.0-dmr/BIN$ tar -tf mysql-group-replication-0.5.0-dmr-amd64.tar.gz | grep group_replication.so
mysql-group-replication-0.5.0-dmr-amd64/lib/plugin/group_replication.so

From now we have mysql group replication plugin for 64 bit Ubuntu 14.04. We will continue our topic about testing group replication plugin in easy ways. There is some other related issues, if you are interested refer to my previous article: Group Replication Plugin issues
