Puppet3 installation in CentOS6.5 Cluster

Puppet3 installation in CentOS6.5 Cluster

Environment: three hosts,

The IP addresses are 10.211.55.11, 12, and 13 respectively.

Install puppet master on 10.211.55.11

Puppet agent is installed on 10.211.55.11, 12, and 13

1. Install puppet Dashboard after the EPEL Library

Yum install yum-priorities

Rpm-ivh https://dl.Fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

Rpm-import https://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6

The source can be replaced with a domestic image.

Http://mirrors.ustc.edu.cn/fedora/epel/epel-release-latest-6.noarch.rpm

Http://mirrors.ustc.edu.cn/fedora/epel/RPM-GPG-KEY-EPEL-6

Modify the/etc/yum. repos. d/epel. repo File

Add an attribute at the end of [epel]

Priority = 11

It means that yum first goes to the official site for source check, and the official site does not go to the epel site for source check.

2. Install the dnsmasq domain name resolution service on 10.211.55.11.

Yum install dnsmasq

Chkconfig dnsmasq on

Service dnsmasq start

Lokkit-p 53: udp (Open Port iptables 53)

Echo "10.211.55.11 node01.myhost.com">/etc/hosts

Modify dnsmasq. conf

Interface = eth0

Listen-address = 10.211.55.11

Bind-interfaces

Resolv-file =/etc/resolv. conf

Addn-hosts =/etc/hosts

Enter

Echo "nameserver 10.211.55.11">/etc/resolv. conf

Change Host Name

1

2

Vi/etc/sysconfig/network

Change to node01.myhost.com, node02.myhost.com, and node03.myhost.com respectively.

Verify that DNS is successful

Netstat-tunlp | grep 53

Dig node02.myhost.com

 

3. Install the time synchronization server on 10.211.55.11.

Yum install ntp

Chkconfig ntpd on
