a key installation shell script redis online database (using the function implementation)

Previous article about the given process manually compile and install redis, and gives the online installation process redis redis building at the time of the simulation cluster, so they think of their own written script redis online installation, the paper mainly use shell functions to achieve and verification process line installation, after the implementation of correct thinking about sharing it.

PS: system environment Centos7.4

Script is as follows:

#!/bin/bash

function  checkroot(){
if [ $UID -ne  0 ]
  then
    echo "|----------------------------------------------------------------------------------------------------------------|"
    echo "|------------------------------------------[权限不足..请切换至root用户]-------------------------------------------|"
    echo "|----------------------------------------------------------------------------------------------------------------|"
    exit;
fi
}

function judge(){
    echo
    off_file=`ls | grep redis-*.tar.gz`
    if [[ "$off_file" = "" ]]
    then
        echo "|----------------------------------------------------------------------------------------------------------------|"
        echo "|-------------------------------------------------[未发现离线包]--------------------------------------------------|"
        echo "|-------------------------------------------------[开始在线安装]--------------------------------------------------|"

    echo "如果你的系统是Centos 7在安装完毕后留意防火墙，可执行以下命令来放行redis 外部通信,若是没有成功则关闭防火墙及SELinux功能。"
