Redis must be restarted after THP is disabled.

至此，Redis已经安装完毕。
5 通过redis-cli，访问和使用Redis：
[root@localhost ~]# /root/redis-4.0.2/src/redis-cli 127.0.0.1:6379> info # Server redis_version:4.0.2 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:1e096713e5234ce6 redis_mode:standalone os:Linux 3.10.0-327.el7.x86_64 x86_64 ... .... 127.0.0.1:6379> set a testredis OK 127.0.0.1:6379> get a "testredis" 127.0.0.1:6379>
接着看文档，继续动手实践。
