Installing the MapR Client on SLES
This section describes how to install the MapR Client on SLES.
- Remove any previous MapR software. You can use
rpm -qa | grep mapr
to get a list of installed MapR packages:
Then type the package names separated by spaces after therpm -qa | grep mapr
zypper rm
command. For example:zypper rm mapr-fileserver mapr-core
- Run the following command to install the MapR client:
zypper install mapr-client
- To use this client with a secure cluster or clusters, copy the
ssl_truststore
file from the/opt/mapr/conf
directory on the cluster to the/opt/mapr/conf
directory on the client. If this client will connect to multiple clusters, merge thessl_truststore
files with the/opt/mapr/server/manageSSLKeys.sh
tool. - Run
configure.sh
to configure the client. In the following examples, the-N
parameter specifies the cluster name, the-c
(lowercase) parameter specifies a client configuration, the-secure
parameter is added if the cluster is secure, the-C
(uppercase) parameter specifies the CLDB nodes, and the-HS
parameter specifies the HistoryServer node. To ensure that the client can connect in the event of a CLDB node failure, all CLDB nodes are specified. For more information about the syntax, parameters, and behavior ofconfigure.sh
, see configure.sh.- Secure cluster example
-
/opt/mapr/server/configure.sh -N my.cluster.com -c -secure -C mynode01:7222,mynode02:7222,mynode03:7222 -HS mynode02
- Non-secure cluster example
-
/opt/mapr/server/configure.sh -N my.cluster.com -c -C mynode01:7222,mynode02:7222,mynode03:7222 -HS mynode02
NOTEIf the cluster was configured with a cluster-admin
user:group
that is different from the defaultmapr:mapr
value, you must include options to specify the cluster-admin user and group information when you runconfigure.sh
to configure the client.If the cluster-admin user ID is present on the client node, include these options:-u
-g
If the cluster-admin user ID is not present on the client node, include these options:-u
-g
--create-user | -a
-U
-G
The following table describes each option:Option Description -u
The user name under which cluster services run. -g
The group name under which cluster services run. --create-user | -a
Creates a local user to run cluster services, using the specified user either from the -u
parameter, or from the environment variable$MAPR_USER
.-U
The user ID to use when creating $MAPR_USER
with the--create-user
or-a
option; corresponds to the-u
or--uid
option of theuseradd
command in Linux.-G
The group ID to use when creating $MAPR_USER
with the-create-user
or-a
option; corresponds to the-g
or-gid
option of theuseradd
command in Linux. - At the end of the client installation, run the
maprlogin password
command to create a valid ticket to connect to the cluster.
