Vertica 7.1安装最佳实践（RHEL6.4）

一、前期准备工作

• 1.1各节点IP和主机名
• 1.2上传脚本并设定环境变量
• 1.3添加信任
• 1.4前期准备检查并调整

二、Vertica安装

三、集群性能评估

一、前期准备工作：

1.1各节点IP和主机名

192.168.1.137 DB01
192.168.1.138 DB02
192.168.1.139 DB03
192.168.1.140 DB04

在节点1配置/etc/hosts,添加上面信息。

1.2上传脚本并设定环境变量

在节点1上传两个安装脚本到/usr/local/bin

cluster_copy_all_nodes 

#!/bin/bash
SELF=`hostname`
if [ -z "$NODE_LIST" ]; then
  echo
  echo Error: NODE_LIST environment variable must be set in .bash_profile
  exit 1
fi

for i in $NODE_LIST; do
  if [ ! $i = $SELF ]; then
    if [ $1 = "-r" ]; then
      scp -oStrictHostKeyChecking=no -r $2 $i:$3
    else
      scp -oStrictHostKeyChecking=no $1 $i:$2
    fi
  fi
done
wait

cluster_run_all_nodes  

#!/bin/bash
if [ -z "$NODE_LIST" ]; then
  echo
  echo Error: NODE_LIST environment variable must be set in .bash_profile
  exit 1
fi

if [[ $1 = '--background' ]]; then
  shift
  for i in $NODE_LIST; do
    ssh -oStrictHostKeyChecking=no -n $i "$@" &
  done
else
  for i in $NODE_LIST; do
    ssh -oStrictHostKeyChecking=no $i "$@"
  done
fi
wait

配置节点1的环境变量

vi /root/.bash_profile       

export NODE_LIST='DB01 DB02 DB03 DB04'

1.3添加信任

ssh-keygen -q -t rsa  -N "" -f  ~/.ssh/id_rsa

ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
