Start mysql when installing cluster (2 replies)

I finally install mysql cluster on two servers and got them running:

[ndbd(NDB)] 2 node(s)
id=2 @xx.xx.xx.xxx (mysql-5.6.25 ndb-7.4.7, Nodegroup: 0, *)
id=3 @yy.yyy.yyy.yyy (mysql-5.6.25 ndb-7.4.7, Nodegroup: 0)

[ndb_mgmd(MGM)] 1 node(s)
id=1 @xx.xx.xx.xxx (mysql-5.6.25 ndb-7.4.7)

[mysqld(API)] 2 node(s)
id=4 @xx.xx.xx.xx (mysql-5.6.25 ndb-7.4.7)
id=5 @yy.yyy.yyy.yyy (mysql-5.6.25 ndb-7.4.7)

But when i run mysql I only got this message:

The program "mysql" can be found in the following packages:
* mysql-client-core-5.5
* mariadb-client-core-5.5
* mysql-client-core-5.6
* percona-xtradb-cluster-client-5.5
Try: apt-get install <selected package>

I can not install these packages because they will conflict with the cluster.

my.conf

[mysqld]
# Options for mysqld process:
ndbcluster # run NDB storage engine

basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
socket= /var/run/mysqld/mysqld.sock


[mysql_cluster]
# Options for MySQL Cluster processes:
ndb-connectstring=46.21.99.140 # location of management server

My cluster is installed under /usr/local/mysql/

My error file do not show any errors usr/local/mysql/data/mycomputer.err

Server1 is running fine with this setup but it is server2 mysql that is not starting.

Does anyone know why I get this message and how to start mysql?
