安装redis
1、将下载好的redis复制到：/opt/software/redis-4.0.9.tar.gz
2、在/opt/software/目录下执行命令：tar -zxvf redis-4.0.9.tar.gz -C /opt/local/
3、进入/opt/local/redis-4.0.9/目录：cd /opt/local/redis-4.0.9
4、执行make install命令；
以上步骤可以将redis安装完成。
将redis设置成开机启动
1、进入redis目录：/opt/local/redis-4.0.9
2、执行命令：./utils/install_server.sh
3、一直默认即可：

所以如果修改redis的配置文件，修改路径应该是：/etc/redis/6379.conf
redis安装目录下的配置文件/opt/local/redis-4.0.9/redis.conf修改会不生效；
如果想要使用/opt/local/redis-4.0.9/redis.conf，修改/etc/init.d/redis_6379文件即可。
redis客户端命令redis-cli任意位置执行
将export PATH=$PATH:/opt/local/redis-4.0.9/redis-cli加入到/etc/profile最后一行
[root@localhost redis-4.0.9]# vi /etc/profile
[root@localhost redis-4.0.9]# source /etc/profile
[root@localhost redis-4.0.9]# redis-cli
