Hi,

I am Sonali looking to participate in this years Google Summer of Code. I
was hoping to contribute to MariaDb.

I tried building MariaDb from source using instructions found here
<https://mariadb.com/kb/en/mariadb/generic-build-instructions/>. Configure,
make and make install were successful. But I faced problem under section
Starting MariaDB for the first time.

When I executed the step:

> scripts/mysql_install_db --user=mysql
>

I received an error saying:
...

So I tried to run mysqld but that didn't work either. I had MySql installed
earlier, but I removed it because it was getting very confusing with that.

I also tried to run from source as mentioned here
<https://mariadb.com/kb/en/mariadb/running-mariadb-from-the-source-directory/>.
But it gives the following error:

> ERROR 2002 (HY000): Can't connect to local MySQL server through socket
> '/tmp/mysql.sock' (111 "Connection refused")

I made sure that I uncommented lines from my.cnf which had sock information
under client and server.

Thanks in advance
