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.

guys really? I told this script NO I DONT WANT REMOVE MY MYSQL. why it removed it and init scripts... oh guys...
and u want give only 12 request for enterprise? with thoose bugs?
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 ;)

T
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

Hello. I have some problems with installation.
Please, tell me, what is cluster controller, what is cmon, what is agent? Where can i read about structure of your product? Is there some limitations on programs place (i mean, what of this must be on some node of cluster, what never must be on node of cluster)?
Here is my case:I have MySQL cluster on one machine (just test it for my purposes).
First of all i was trying to install all to the same machine with install-cc.sh. It did not work (just didn't log in, i was trying to add values to database by myself, but it did not help).
Now i'm trying to install it manually. I'm running cluster at one machine with ip 192.168.1.36. I have installed cluster control on the same host, moreover it's working now and there is no error messages in log file except some warnings like "can't pull log <something>". After that i have tried to install gui with install-cc.sh, and i did it (i have chosen "do not install cc). I successfully logged in, but there was no info about my cluster. When i choose "add existing cluster"->"MySQL" and input all parameters, i get this:
170 - Message sent to controller
171 - Verifying job parameters.
172 - Verifying controller host and cmon password.
173 - Verifying the SSH connection to 192.168.1.36.
174 - Verifying the MySQL user/password.
175 - Found 1 nodes.
176 - Checking the nodes that those aren't in other cluster.
Host (192.168.1.36) is already in an other cluster.
Here is my /etc/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=default_cluster_1
agentless=1
os = [redhat|debian]
os=debian
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=mysqlcluster
location of mysql install, e.g /usr/ or /usr/local/mysql
mysql_basedir=/opt/mysql/server-5.6/
CMON DB config - mysql_password is for the 'cmon' user
mysql_port=3306
mysql_hostname=192.168.1.36
mysql_password=cmon
#hostname is the hostname of the current host
hostname=test_hostname
ndb_connectstring - comma-separated list of management servers: a:1186,b:1196
ndb_connectstring=192.168.1.36:1186
The user that can SSH without password to the oter 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=192.168.1.36
mgm and data nodes are only used to MySQL Cluster "," or " " sep. list
datanode_addresses=192.168.1.36
mgmnode_addresses=192.168.1.36
wwwroot=/var/www/
configuration file directory for database servers (location of config.ini, my.cnf etc)
on RH, usually it is /etc/, on Debian/Ubuntu /etc/mysql. If different please set:
db_configdir=/home/user/Cluster/53/
Hi Alex,
What did you mean by 'broke the base' and 'it brokes all again'? There are several ways to get ClusterControl installed, as described in details in this blog post: http://www.severalnines.com/blog/several-ways-install-clustercontrol . Each DB cluster need to have a dedicated ClusterControl host.
When you 'add existing galera cluster' using ClusterControl A (CC A), you need to have CC W and Galera X,Y,Z ready (need to have separate ClusterControl server). If you are using bootstrap script, you can install ClusterControl directly inside CC W, without the need to use CC A.
The functionality has limited support on SSH port and we are going to introduce a new way of importing existing Galera cluster in our next version (1.2.6) which scheduled to be released next week.
Regards,
Ashraf
LOL ))) I used 22 ports on all machines, than I add a cluster) and what?)) it brokes all again)))

how does it check it? and where is the log?
why I cant change port when trying to add cluster?
okey. it installed. and what I got? IT BROKES THE BASE! i have no one cluster. lol)))) gonna go to snapshot))
rly guys, we want to buy it, but fix it please) how we can use it)
u got a lot problems wih IPs and hostnames.

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 ?
and more. its install socat earlier. why 2 times?
when I takink package. and trying to install it error are:

Hi Alex,
The default HAproxy statistic page username and password are admin/admin. You can change it inside /etc/haproxy/haproxy.cfg.

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

Hi,
I reinstalled the cluster using the http://www.severalnines.com/cluster-configurator/ and it seems to be working fine now,
René
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 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
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..
Thank Everyone , I has been finish project . I reinstall cluster mysql & cluster control server. Great, It was running . Regard !
