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

 root@hello:~# docker run -p 6379:6379 --name redis -v /data/redis/redis.conf:/etc/redis/redis.conf  -v /data/redis/data:/data -d redis redis-server /etc/redis/redis.conf --appendonly yes
