1186 is the default port that the MySQL Cluster management node uses (can be override it in config.ini). When you run ndb_mgmd, it will listen to that port.

Regards, Andrew.

I´ve followed the instructions, and found some problems on ubuntu 10.04 and MySqlCluster 7.0.13 .

I´d like to share this to people who migth find the same problems on ubuntu.

First, the base_dir must be owned by mysql user( “mysql” in my system), else scripts/mysql_install_db fails to install the databases.
It took me a while to discover this, but scripts/mysql_install_db runs flawlessly after running

shell>chown -R mysql “extracted folder” ( in this guide /home/billy/mysql/7_0_6 )

after creating the data folders

Then, in the my.*.conf files, you must alter three lines :

1.-> “log-bin” should read “log-bin=auth-bin” (or whatever log type you want ) to get rid of this warning when running mysqld

” No argument was provided to –log-bin, and –log-bin-index was not used; so replication may break when this MySQL server acts as a master and has his hostname changed!! Please use ‘–log-bin=auth-bin’ to avoid this problem. ”

2.-> You must add this line “user=mysql” to run bin/mysql without errors and security warnings

3.-> Also,you should include “socket=/tmp/my.*.sock”
were * is the nomber of the config file name(you could use whatever file name you want, they just have to be different for each config file) to connect to servers using bin/mysql.

The command should be :

shell>bin/mysql -h localhost -P 3306 \ –socket=/tmp/my.1.sock

to avoid this error :

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)

So, finally the conf/my.1.conf file should look like this :

[mysqld]
user=mysql
ndb-nodeid=4
ndbcluster
datadir=”basedir”/data/data1
basedir=”basedir”
port=3306
server-id=1
log-bin=auth-bin
socket=/tmp/my.1.sock

Hope this helps to get this demo install running on Lucid Lynx

Thanks again for your guide.

Great article – thanks a lot! I am really looking forward to the article you mentioned redarding the distribution amongst multiple servers.

Cheers,
Phil
