【Redis】Redis 编译安装配置优化，多实例配置
1、下载redis源码包，并进行解压缩操作https://download.redis.io/releases/
# wget https://download.redis.io/releases/redis-5.0.14.tar.gz

2、创建redis用户，创建redis目录结构并授权
# useradd redis -s /sbin/nologin
# mkdir /app/redis/{etc,log,data,run} -p
# chown redis.redis /app/redis/ -R
# id redis
uid=2006(redis) gid=2006(redis) groups=2006(redis)
# ll /app/redis/
total 24

drwxr-xr-x 3 rootroot4096 Apr 13 21:36 ../
drwxr-xr-x 2 redis redis 4096 Apr 13 21:36 data/
drwxr-xr-x 2 redis redis 4096 Apr 13 21:36 etc/
drwxr-xr-x 2 redis redis 4096 Apr 13 21:36 log/
drwxr-xr-x 2 redis redis 4096 Apr 13 21:36 run/3、准备编译环境，安装 build-essential （如已具备可忽略）
# apt-get install build-essential -y
