Rhel automatic installation of zookeeper shell scripts

Rhel automatic installation of zookeeper shell scripts

A: This script runs the machine, Linux RHEL6

B,c,d,... : Machine to be installed zookeeper cluster, Linux RHEL6

First, on machine A that the script runs, determine that you can log on to the machine b,c,d to install ZK without password ssh,... , then you can run this script on a:

$./install_zookeeper

Premise:

B, C, D machine must be configured well repo, this script uses Cdh5 repo, the following content is saved to:/etc/yum.repos.d/cloudera-cdh5.repo:

[cloudera-cdh5]# Packages for Cloudera's distribution for Hadoop, Version 5, on Redhator CentOS 6 X86_64name=cloudera ' s Di Stribution for Hadoop, Version 5baseurl=http://archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/5/gpgkey =/http Archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/rpm-gpg-key-cloudera    Gpgcheck = 1enabled  = 1

The automatic installation script will automatically install the zookeeper on the B,c,d machine and configure the relevant configuration file. But did not start them. Support for 1,3,5,7 servers.

Modify the last line according to the configuration:

Install_zookeeper "2181" "192.168.122.201" "192.168.122.202" "192.168.122.203"

Note: You need to stop the firewall on each zk-cluster machine and start the zookeeper:

$/usr/lib/zookeeper/bin/zkserver.sh Start-foreground
