shell脚本一键部署redis

脚本说明：
1、版本为：redis-6.2.6.tar.gz，下载地址为:https://download.redis.io/releases/redis-6.2.6.tar.gz
2、需要有yum安装gcc和gcc-c++，自行安装下
3、若需要部署三台服务器6节点的集群，每台服务器分别执行脚本，然后选择集群模式，部署完执行添加集群命令即可，命令如下：

建立集群：在任意服务器上输入命令：（redis有密码，需要在改命令后加 -a <密码>）
./redis-cli --cluster create 192.168.81.225:6379 192.168.81.225:6380 192.168.81.227:6379 192.168.81.227:6380 192.168.81.228:6379 192.168.81.228:6380  --cluster-replicas 1 -a <密码>

脚本内容如下：

#!/bin/sh
#tar包部署安装redis单机
#tar包部署安装redis单机2实例脚本，占用端口6379和6380

#判断有无要安装的redis包
if [ -e /data/redis-6.2.6.tar.gz ];then
    continue
else
    echo -e '\\033[35m /data目录中没有安装包[redis-6.2.6.tar.gz]\\033[0m'
    exit
fi

bushu()
#获取密码和本机ip
read -p "输入你要创建redis用户的密码: " passwd
ip=`/sbin/ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6|awk 'NR==1 print $2'`

#解压并安装
cd /data
tar xf redis-6.2.6.tar.gz
cd redis-6.2.6
make && make install
