If you have not used the Configurator to setup your cluster you can still install ClusterControl on your existing database cluster. Make sure the database cluster is running in full capacity prior to this installation.
Please follow the instructions here in our Getting Started Guide.

Hi Vladimir,
You need a dedicated host for Clustercontrol (we do not recommend you to co-host ClusterControl with the database cluster). Please refer to ClusterControl Administration Guide here for details:
http://www.severalnines.com/docs/clustercontrol-administration-guide
You can also refer to our ClusterControl Quick Start guide to get ClusterControl installed on top of your existing database cluster:
http://www.severalnines.com/docs/clustercontrol-quick-start-guide

Hi Gents,
I had a similar issue with this error:
380 - Message sent to controller
381 - Verifying job parameters.
382 - Verifying controller host and cmon password.
383 - Verifying the SSH connection to 10.10.14.10.
384 - Verifying the MySQL user/password.
385 - Found 1 nodes.
386 - Checking the nodes that those aren't in other cluster.
Host (10.10.14.19) is already in an other cluster.
I have found that when I delete an existing cluster out of ClusterControl on version 1.2.6, it does not remove the .cnf file that is part of cmon in /etc/cmon.d/
All I did was remove the .cnf that pertained to my host, and re-added the cluster.
If you still get this error in the CMON DB, under the "hosts" table delete the entries there that pertain to your hosts ;)

Hi ! I'd just install cmon + CC UI on separate node. I tuned cmon.cfg and it work fine all data collecting from my galera cluster, but when i try to use UI i got nothing.
I added existing cluster via form and in Job window i see just a message - Message sent to controller and no progress.
What i did make wrong and how append existing cluster to UI ?
Hi Alexandr,
Did you follow this guide to install: http://www.severalnines.com/docs/clustercontrol-quick-start-guide/existing-cluster/clustercontrol-ui ?
What is the operating system that you used? Also please attach /etc/cmon.cnf here (you can hide the mysql_password value).
Regards,
Ashraf
Hi Ashraf !
Yes i follow this instruction. This my cmon.cnf
#cmon config file
id and name of cluster that this cmon agent is monitoring.
Must be unique for each monitored cluster, like server-id in mysql
cluster_id=1
name=cluster_1
agentless=1
os = [redhat|debian]
os=redhat
skip_name_resolve = [0|1] - set 1 if you use ip addresses only everywhere
skip_name_resolve=1
mode = [controller|agent|dual]
mode=controller
type = [mysqlcluster|replication|galera]
type=galera
CMON DB config - mysql_password is for the 'cmon' user
mysql_port=3306
mysql_hostname=127.0.0.1
mysql_password=*****
local_mysql_port=*****
local_mysql_password=*****
location of mysql install, e.g /usr/ or /usr/local/mysql
mysql_basedir=/usr
#hostname is the hostname of the current host
hostname=
ndb_connectstring - comma-separated list of management servers: a:1186,b:1196
ndb_connectstring=127.0.0.1
The user that can SSH without password to the other nodes
os_user=root
location of cmon.pid file. The pidfile is written in /tmp/ by default
pidfile=/var/run/
logfile is default to syslog.
logfile=/var/log/cmon.log
collection intervals (in seconds)
db_stats_collection_interval=30
host_stats_collection_interval=30
mysql servers in the cluster. "," or " " sep. list
mysql_server_addresses=ip of one galera's node
mgm and data nodes are only used to MySQL Cluster "," or " " sep. list
datanode_addresses=
mgmnode_addresses=
wwwroot=/var/www/html
configuration file directory for database servers (location of config.ini, my.cnf etc)
on RH, usually it is /etc/, on Debian/Ubuntu /etc/mysql
#db_configdir=
ssh_port=***
ssh_identity=/root/.ssh/id_rsa
Hi Alexandr,
If you followed the quick start guide, you don't necessary need to tweak cmon.cnf's parameters. But when you do, please specify following two mandatory parameters:
hostname=[your clustercontrol IP]
mysql_server_addresses='[dbhost_ip1,dbhost_ip2,dbhost_ip3]'
*replace the respective values accordingly
Ensure that you can perform passwordless ssh to from ClusterControl node to galera node:
ssh -i /root/.ssh/id_rsa -p [ssh_port] root@[one of the galera node's IP address]
Once done, restart cmon and monitor the output of /var/log/cmon.log.
Regards,
Ashraf
Hi, Ashraf !
I did review my config:
1). mysql_server_addresses was set i just hide it on my post;
2). i set hostname to local ip
after that looks like all start working, but when i try to add cluster i got next error:
177 - Getting node list from the MySQL server.
Failed to detect galera nodes: wsrep_cluster_address=gcomm://.Choose a node with wsrep_cluster_address=gcomm://.

Hi kid_pig,
Is the MySQL server running on 172.16.200.27? Please verify it with this command on 172.16.200.27:
$ service mysql status
$ ps -ef | grep mysql
$ mysql -uroot -p'[mysql root password]' -hlocalhost -p[mysql port]
$ mysql -uroot -p'[mysql root password]' -h127.0.0.1 -p[mysql port]
Make sure all commands mentioned above are executed correctly (without error). Once done, retry again with the adding.

Ashraf

Hi kid_pig,
Your /etc/hosts is fine. The error indicates that CC couldn't connect to MySQL using socket. You have specified wrong command though:
$ mysql -uroot -hlocalhost -p3306
It supposed to be:
$ mysql -uroot -p123456 -hlocalhost -p3306
I would advise you to check the mysql error log located at /var/log/mysql/error.log and make sure MySQL able to connect through socket. Then, try again to add the Galera cluster.

Ashraf
hi Johan,
does the cmon ui (limited account) have features enabled for mysql-cluster or is it paid ?
i set up my own ndb cluster with out configurator.
i setup my cmon ... it connected to my management node and all... but the UI does show it anywhere.
do let me know mysql-cluster monitoring via cmon is free or do i need a licencese purchage.
thanking you
with regards,
ch Vishnu
Greetings Vishnu!
You should be able to monitor your MySQL Cluster as part of the community edition.
Can you explain the steps you took?
Did you manually install ClusterControl on top of your existing MySQL Cluster using the instructions in this article.
Or did you do the automated install using the Bootstrap script?
http://support.severalnines.com/entries/21952156-Get-Your-Database-Cluster-Under-ClusterControl-
Thank Everyone , I has been finish project . I reinstall cluster mysql & cluster control server. Great, It was running . Regard !
I've succesfully installed the clustercontrol on a dedicted host and have added the cluster to the control server.
I am also able to see the controller node and the mysql nodes, but I'm unable to see the Management nodes (also installed on the mysql nodes) and the Data nodes. I used the installer script (s9s_bootstrap --install).
The CMON log is not showing only a few errors;
Jul 24 06:30:10 : (ERROR) Can't get a connected management server (which repeats every hour)
and
Jul 24 07:30:10 : (ERROR) Creating processlist failed, failed to get Datadir, no connected ndb_mgmd was found. (also every hour)
Any pointers would be appreciated..
Hi Rene,
did you add
ndb_connectstring="<mgmhost1>,<mgmhost2>"
to /etc/cmon.cnf?
Where are the ndb binaries located?
You may have to set, e.g:
mysql_basedir=/opt/mysqlcluster/
Do you have a firewall between the controller and the mysql cluster, blocking port 1186?
BR
johan
Hi Johan,
the ndb_connectstring is filled with the IP addresses of the correct hosts (and ports).
I can also connect to those two hosts from the Controller server using telnet ipaddress port, so the TCP connection/firewall looks to be configured correctly.
The controller server has the normal MySQL installed from Debian, not the cluster mysql. The controller server currently has no ndb binaries.
Do I need to set the mysql_basedir to the location of the mysql cluster basedir? Or do I need to copy over the cluster files to the controller server?
Hi,
I reinstalled the cluster using the http://www.severalnines.com/cluster-configurator/ and it seems to be working fine now,
René
