今天小編給大家分享一下docker怎么安裝redis掛載容器卷同時開啟持久化的相關知識點，內(nèi)容詳細，邏輯清晰，相信大部分人都還太了解這方面的知識，所以分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后有所收獲，下面我們一起來了解一下吧。
說明：centOS操作系統(tǒng)，操作系統(tǒng)已安裝過redis，端口6379已被占用。容器將會使用6380端口。本次操作為了實例化redis數(shù)據(jù)，并掛載到宿主機，防止容器被刪除導致的數(shù)據(jù)丟失！
[root@localhost]# docker search --limit 10 redis [root@localhost]# docker pull redis
[root@localhost redis]# pwd /docker/redis
復制原有redis.conf到/docker/redis/目錄下
修改配置（最重要主要4項：修改后臺運行默認為no、端口、存放位置、開啟持久化）：
requirepass 123 maxclients 10000 #如果要外網(wǎng)訪問，請注釋掉下面，或者修改為0.0.0.0，保險起見，也可以把protected-mode設置為no bind 0.0.0.0 protected-mode no #注意修改這里端口，根據(jù)你實際暴露端口情況配置 port 6380 tcp-backlog 511 timeout 0 tcp-keepalive 300 #注意這里要把后臺運行設置為no，避免docker后臺運行沖突 daemonize no supervised no pidfile /docker/redis/redis.pid loglevel notice databases 16 always-show-logo yes save 900 1 save 300 10 save 60 10000 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dbfilename dump.rdb #注意修改這里的目錄為容器內(nèi)目錄，默認reids進來是在/data/目錄 dir /data/ replica-serve-stale-data yes replica-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no replica-priority 100 lazyfree-lazy-eviction no lazyfree-lazy-expire no lazyfree-lazy-server-del no replica-lazy-flush no #注意修改這里的配置，yes開啟持久化，no關閉持久化 appendonly yes appendfilename "appendonly.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes aof-use-rdb-preamble yes lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 latency-monitor-threshold 0 notify-keyspace-events "" hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-size -2 list-compress-depth 0 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 hll-sparse-max-bytes 3000 stream-node-max-bytes 4096 stream-node-max-entries 100 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit replica 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 dynamic-hz yes aof-rewrite-incremental-fsync yes rdb-save-incremental-fsync yes
啟動命令：docker run -p 6380:6380 --name forredis2 --privileged=true -v /docker/redis/redis.conf:/etc/redis/redis.conf -v /docker/redis/data:/data -d redis
效果如下：
[root@localhost]# docker run -p 6380:6380 --name forredis2 --privileged=true -v /docker/redis/redis.conf:/etc/redis/redis.conf -v /docker/redis/data:/data -d redis d536dd728243ccee23b78e0289e30f7ee25084d308766fb9aa317d691d0dea7d [root@localhost]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES d536dd728243 redis "docker-entrypoint.s…" 3 seconds ago Up 2 seconds 6379/tcp, 0.0.0.0:6380->6380/tcp, :::6380->6380/tcp forredis2參數(shù)講解：

-d redis[:版本號]

如果要后臺運行，將啟動redis命令后加上&，即
redis-server /etc/redis/redis.conf &
“/etc/redis/redis.conf”為容器內(nèi)配置文件，已通過啟動容器時掛載到宿主機的/docker/redis/redis.conf
root@ce16f8c4fd8c:/data# redis-cli -p 6380 127.0.0.1:6380> auth 123 OK 127.0.0.1:6380> keys * (empty array) 127.0.0.1:6380> set a 1 OK 127.0.0.1:6380> keys * 1) "a"
為了驗證redis持久化，刪除容器后數(shù)據(jù)在宿主機不會丟失，我們嘗試刪除容器后重新啟動
[root@localhost ~]# docker rm -f forredis2 forredis2 [root@localhost ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e28f2bd4b59e redis "docker-entrypoint.s…" 10 hours ago Exited (130) 10 hours ago exciting_yalow 4e291d491cda redis "docker-entrypoint.s…" 10 hours ago Exited (0) 10 hours ago dreamy_rhodes be3f2f06ed9f redis "docker-entrypoint.s…" 12 hours ago Exited (0) 12 hours ago awesome_jones 9a206e517842 redis "docker-entrypoint.s…" 12 hours ago Exited (0) 12 hours ago hopeful_volhard 69c9f429c98a 7614ae9453d1 "docker-entrypoint.s…" 16 hours ago Exited (1) 16 hours ago youthful_goodall 25f26d7892d5 redis "docker-entrypoint.s…" 18 hours ago Exited (0) 16 hours ago amazing_lovelace [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES [root@localhost ~]# cd /docker/redis/data/ [root@localhost data]# ls appendonly.aof dump.rdb
[root@localhost data]# docker run -p 6380:6380 --name forredis2 --privileged=true -v /docker/redis/redis.conf:/etc/redis/redis.conf -v /docker/redis/data:/data -d redis d536dd728243ccee23b78e0289e30f7ee25084d308766fb9aa317d691d0dea7dc
重復第【二】步的操作，進入redis，查看數(shù)據(jù)是否存在
[root@localhost ~]# docker exec -it forredis2 /bin/bash root@d536dd728243:/data# redis-cli -p 6380 127.0.0.1:6380> auth 123 127.0.0.1:6380> keys * 1) "a"
數(shù)據(jù)存在，成功！
