Redis各模式搭建到放弃 ​

CentOS7编译安装Redis5 ​

shell
#!/bin/bash
# 安装路径: /usr/local/redis
cd /usr/local
wget http://download.redis.io/releases/redis-5.0.0.tar.gz
tar -xzvf redis-5.0.0.tar.gz
cd redis-5.0.0
make
make install PREFIX=/usr/local/redis
cp redis.conf sentinel.conf /usr/local/redis/
cd /usr/local/redis
mkdir data log var

Redis单主 ​

万一db文件有损，直接凉凉
