WebScaleSQL Installation attempted... part 1

Well if you have not see the news yet, then by all means follow this link and read about WebScaleSQL. Many thanks to the team of engineers from Facebook, Twitter and Google for their hard work on this. I am curious to see how this develops more in the future, once I get it to work.

Here is what I encountered so far. I wanted this to be a successful blog post, instead it will be part one until I get it running.

I figured I would put up a little how to install WebScaleSQL for those of you new to Github any of this. It takes feedback from the community after all, so the community needs to be able to install and try it out.

For this example I took the pre-built Oracle Linux Virtual Box image. I had one already but it is available here : http://www.oracle.com/technetwork/server-storage/linux/downloads/vm-for-hol-1896500.html.

It should be obvious that WebScaleSQL is not intended for use on a VirtualBox in production, but this is just a demo. I assumed that it meant that people do not have an excuse to try it out since anyone can download and use this with VirtualBox. I did have to enable the additional disk that come with the image so you have enough space. To format, partition and mount the disks all can be done via disk utility.  The finished product for my example is below.

[root@oraclelinux6 oracle]# ls -al /media/
drwx------  3 oracle oracle 4096 Mar 27 16:19 webscaledisk
drwx------  3 oracle oracle 4096 Mar 27 16:21 workspace
[root@oraclelinux6 oracle]# chmod 777 /media/workspace/
[root@oraclelinux6 oracle]# chmod 777 /media/webscaledisk/

The code for WebScaleSQL is available on Github. The zip file can be downloaded here. I choose to check out the code via the github code repository methods. If others need help with the SSH keys see the Gitbhub reference page.

The git package is not available on Oracle Linux but that is quickly solved if you plan to use the Github version.

[oracle@oraclelinux6 ~]$ sudo bash
[root@oraclelinux6 oracle]# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
[root@oraclelinux6 oracle]# wget http://git-core.googlecode.com/files/git-1.7.10.1.tar.gz
[root@oraclelinux6 oracle]# tar -xvzf git-1.7.10.1.tar.gz
[root@oraclelinux6 oracle]# cd git-1.7.10.1
[root@oraclelinux6 git-1.7.10.1]# make prefix=/usr/local all
[root@oraclelinux6 git-1.7.10.1]# make prefix=/usr/local install
[root@oraclelinux6 git-1.7.10.1]# exit
$ git --version
git version 1.7.10.1

Once git and the ssh-keys are ready you can download:

[oracle@oraclelinux6 ~]$ cd /media/workspace/
[oracle@oraclelinux6 workspace]$ git clone https://github.com/webscalesql/webscalesql-5.6.git
Cloning into 'webscalesql-5.6'...

OK so however you decided to get the code... Lets us now try to get it installed.  To be clear this is should nothing new, this is a basic MySQL source install but it is just using the WebScaleSQL package.  It basically follows the same procedure as I did here before.

I needed a few dependancies on this clean system first. You might find you need some as well, it all depends on your system and the result of the cmake command below.


[root@oraclelinux6 workspace]# yum -y install ncurses-devel  readline-devel cmake gcc gcc-c++ bison-devel bison
[root@oraclelinux6 workspace]# wget http://googlemock.googlecode.com/files/gmock-1.6.0.zip
[root@oraclelinux6 workspace]# unzip gmock-1.6.0.zip
[root@oraclelinux6 workspace]# cd gmock-1.6.0
[root@oraclelinux6 gmock-1.6.0]# ./configure
[root@oraclelinux6 gmock-1.6.0]# make
[root@oraclelinux6 gmock-1.6.0]# make check
....
=====================================================
1 of 4 tests failed
Please report to googletestframework@googlegroups.com
=====================================================
make[2]: Leaving directory `/media/workspace/gmock-1.6.0/gtest'
make[1]: Leaving directory `/media/workspace/gmock-1.6.0/gtest'

OK so the next phase (part 2) should be the following once I get the google code to work...

Btw the denable_downloads should download and install the gmock as well but it also fails.

[root@oraclelinux6 workspace]# groupadd mysql
[root@oraclelinux6 workspace]# useradd -r -g mysql mysql
[root@oraclelinux6 workspace]# ln -s /media/workspace/webscalesql-5.6/ /usr/local/mysql
[root@oraclelinux6 workspace]# chown -R mysql:mysql webscalesql-5.6/
[root@oraclelinux6 workspace]# cd webscalesql-5.6/
[root@oraclelinux6 webscalesql-5.6]# cmake -DENABLE_DOWNLOADS=1 .
make
make install
./scripts/mysql_install_db --user=mysql
chown -R root .
chown -R mysql data

So not ready just yet.. but I will get back with you all once I get it working. I have faith I will.
