docker方式实现redis数据持久化离线安装

保存镜像

root@hello:~# docker pull redis:latestlatest: Pulling from library/redisa2abf6c4d29d: Already exists c7a4e4382001: Pull complete 4044b9ba67c9: Pull complete c8388a79482f: Pull complete 413c8bb60be2: Pull complete 1abfd3011519: Pull complete Digest: sha256:db485f2e245b5b3329fdc7eff4eb00f913e09d8feb9ca720788059fdc2ed8339Status: Downloaded newer image for redis:latestdocker.io/library/redis:latestroot@hello:~# root@hello:~# docker save > redis.tar redis:latest root@hello:~# root@hello:~# ll redis.tar -rw-r--r-- 1 root root 116304384 Mar 30 07:30 redis.tarroot@hello:~#

导入镜像

root@hello:~# docker load -i redis.tar 2edcec3590a4: Loading layer [==================================================>] 83.86MB/83.86MB9b24afeb7c2f: Loading layer [==================================================>] 338.4kB/338.4kB4b8e2801e0f9: Loading layer [==================================================>] 4.274MB/4.274MB529cdb636f61: Loading layer [==================================================>] 27.8MB/27.8MB9975392591f2: Loading layer [==================================================>] 2.048kB/2.048kB8e5669d83291: Loading layer [==================================================>] 3.584kB/3.584kBLoaded image: redis:latest

创建目录，修改配置

root@hello:~# mkdir /data/redis -proot@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 yesa59d3137a3ade6ec05588e0895d2265aff0e81746ec1847553fef6bd4df59348root@hello:~#
