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：
[root@localhost redis-4.0.9]# ./utils/install_server.sh
Welcome to the redis service installer
This script will help you easily set up a running redis server
Please select the redis port for this instance: [6379]
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf]
Selected default - /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log]
Selected default - /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379]
Selected default - /var/lib/redis/6379
Please select the redis executable path [/usr/local/bin/redis-server]
Selected config:
Port : 6379
Config file : /etc/redis/6379.conf
Log file : /var/log/redis_6379.log
Data dir : /var/lib/redis/6379
Executable : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379
Installing service...
Successfully added to chkconfig!

Starting Redis server...
Installation successful!
以上操作可以将redis设置为开机启动。
PS：通过这种方式这是redis开机启动，redis的配置文件路径：/etc/redis/6379.conf
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
