创建目录，修改配置

root@hello:~# mkdir /data/redis -p
root@hello:~# mkdir /data/redis/data -p


root@hello:~# cp -p redis.conf /data/redis/
root@hello:~# vim /data/redis/redis.conf

修改redis.conf配置文件：

主要配置的如下：

bind 127.0.0.1 #注释掉这部分，使redis可以外部访问

daemonize no#用守护线程的方式启动

requirepass thinekr #给redis设置密码

appendonly yes #redis持久化　　默认是no

tcp-keepalive 300 #防止出现远程主机强迫关闭了一个现有的连接的错误默认是300

启动容器
