安装Redis

https://redis.io/

1.源码包安装
# tar -zxf redis-4.0.6.tar.gz -C /usr/local/
# cd /usr/local/ && mv redis-4.0.6 redis
# cd redis
# vim redis.conf, 修改如下：
bind 0.0.0.0 # 可以从任何IP访问
daemonize yes # 允许作为后台服务运行
# redis-server ./redis.conf
# ps -ef | grep redis
# redis-cli
127.0.0.1:6379> set key1 123456
OK
127.0.0.1:6379> get key1
"123456"
127.0.0.1:6379> exit


2.增加访问密码
# vim redis.conf 
requirepass bigdata
# redis-cli
127.0.0.1:6379> shutdown save # 关闭redis
not connected> exit
# ps -ef |grep redis
root       6410   2440  0 17:53 pts/0    00:00:00 grep --color=auto redis
# redis-server ./redis.conf # 启动redis
# redis-cli
127.0.0.1:6379> get key1
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth bigdata
OK
127.0.0.1:6379> get key1

"123456"

3.将redis设置成系统服务
# pwd
/usr/local/redis
# cd utils/
# ./install_server.sh
