查看yum install 安装redis的安装路径

1. 查询redis安装包
   命令：
		rpm -qa | grep redis
   result:
		redis-3.2.12-2.el7.x86_64
2. 通过安装包查询redis相关文件的安装目录
	命令：
		rpm -ql redis-3.2.12-2.el7.x86_64	
	result:
		/etc/logrotate.d/redis
		/etc/redis-sentinel.conf
		/etc/redis.conf	（redis配置文件，配合redis-server启动redis）
		/etc/systemd/system/redis-sentinel.service.d
		/etc/systemd/system/redis-sentinel.service.d/limit.conf
		/etc/systemd/system/redis.service.d
		/etc/systemd/system/redis.service.d/limit.conf
		/usr/bin/redis-benchmark
		/usr/bin/redis-check-aof
		/usr/bin/redis-check-rdb
		/usr/bin/redis-cli
		/usr/bin/redis-sentinel
		/usr/bin/redis-server （这个就是我想要的，用来启动redis）
		/usr/lib/systemd/system/redis-sentinel.service
		/usr/lib/systemd/system/redis.service
		/usr/libexec/redis-shutdown
