三种启动方式：
- 动态参数启动（指定端口号）
- 配置文件启动（生产环境推荐）
- 最简单启动
官方安装指南
安装前置环境gcc-c++
$ yum install -y gcc-c++$ wget http://download.redis.io/releases/redis-5.0.0.tar.gz
$ tar xzf redis-5.0.0.tar.gz
$ cd redis-5.0.0
$ make MALLOC=libc
$ make install编译后在src目录下生成可执行文件
$ ls | grep redis-redis-benchmark ——性能测试

redis-check-aof ——aof修复
redis-check-aof.c
redis-check-aof.o
redis-check-rdb ——rdb修复
redis-check-rdb.c
redis-check-rdb.o
redis-cli ——客户端
redis-cli.c

2660:M 21 Nov 2018 20:01:10.961 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
