导入镜像

root@hello:~# docker load -i redis.tar 2edcec3590a4: Loading layer [==================================================>]83.86MB/83.86MB 9b24afeb7c2f: Loading layer [==================================================>]338.4kB/338.4kB 4b8e2801e0f9: Loading layer [==================================================>]4.274MB/4.274MB 529cdb636f61: Loading layer [==================================================>]27.8MB/27.8MB 9975392591f2: Loading layer [==================================================>]2.048kB/2.048kB 8e5669d83291: Loading layer [==================================================>]3.584kB/3.584kB Loaded image: redis:latest

创建目录，修改配置

root@hello:~# mkdir /data/redis -p root@hello:~# mkdir /data/redis/data -proot@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 a59d3137a3ade6ec05588e0895d2265aff0e81746ec1847553fef6bd4df59348 root@hello:~#
