二百零六、Flume——Flume1.9.0单机版部署脚本（附截图）

一、目的

在实际项目部署时，要实现易部署易维护，需要把安装步骤变成安装脚本实现快速部署

二、部署脚本在Linux中文件位置

文件夹中只有脚本文件flume-install.sh和tar包apache-flume-1.9.0-bin.tar.gz

三、Flume安装脚本

#!/bin/bash

#获取服务器名称和用户名
hostname=`hostname`
echo "current host name is $hostname"
whoami=`whoami`
echo "current user is $whoami"

#flume下载路径
installdir=/usr/local/hurys/dc_env/flume
if [ ! -d "$installdir" ];then
mkdir $installdir
fi

#日志文件
nowpath=$(cd "$(dirname "$0")";pwd)
logDir=$nowpath/log/
cd $nowpath
if [ ! -d $logDir ];then
mkdir -p $logDir
fi
nowtime=`date --date='0 days ago' "+%Y%m%d%H%M%S"`
daytime=`date --date='0 days ago' "+%Y%m%d"`
log_file="$logDir/flume_$daytime.log"
