1、拉取Redis镜像
docker pull redis
2、 这里可以查看一下自己是否下载成功：
[root@localhost redis-6379]# docker images redis REPOSITORY TAG IMAGE ID CREATED SIZE redis latest df5748206578 32 hours ago 98.3MB
3、 创建目录(宿主机)
3.1 配置文件目录
mkdir -p /root/docker/redis-6379/conf
在该目录下放置redis.conf配置文件
注：目录可以自定义
3.2 数据目录
mkdir -p /root/docker/redis-6379/data
4、启动容器，加载配置文件并持久化数据
docker run -d --privileged=true -p 6379:6379 --restart always -v /root/docker/redis-6379/conf/redis.conf:/etc/redis/redis.conf -v /root/docker/redis-6379/data:/data --name myredis redis redis-server /etc/redis/redis.conf --appendonly yes --requirepass "123456"
4.1 涉及到的命令行参数
-d -> 以守护进程的方式启动容器 -p 6379:6379 -> 绑定宿主机端口 --name myredis -> 指定容器名称 --restart always -> 开机启动 --privileged=true -> 提升容器内权限 -v /root/docker/redis-6379/conf:/etc/redis/redis.conf -> 映射配置文件 -v /root/docker/redis-6379/data:/data -> 映射数据目录 redis-server /etc/redis/redis.conf --appendonly yes -> 在容器里执行redis-server命令，打开redis持久化 --requirepass -> 密码
5、查看启动镜像
docker ps
6、进入到容器
[root@localhost redis-6379]# docker exec -it myredis redis-cli 127.0.0.1:6379> info # Server redis_version:5.0.9 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:c781f6fafb441952 redis_mode:standalone os:Linux 3.10.0-693.el7.x86_64 x86_64 arch_bits:64 multiplexing_api:epoll atomicvar_api:atomic-builtin gcc_version:8.3.0 process_id:1 run_id:3ea7227ca4dc4f17935e5b382f86a0a6aa2abbd9 tcp_port:6379 uptime_in_seconds:1253 uptime_in_days:0 hz:10 configured_hz:10 lru_clock:10464647 executable:/data/redis-server config_file:/etc/redis/redis.conf # Clients connected_clients:2 client_recent_max_input_buffer:2 client_recent_max_output_buffer:0 blocked_clients:0 # Memory used_memory:875120 used_memory_human:854.61K used_memory_rss:11177984 used_memory_rss_human:10.66M used_memory_peak:875120 used_memory_peak_human:854.61K used_memory_peak_perc:100.12% used_memory_overhead:857928 used_memory_startup:791312 used_memory_dataset:17192 used_memory_dataset_perc:20.51% allocator_allocated:1500440 allocator_active:1806336 allocator_resident:8699904 total_system_memory:16650436608 total_system_memory_human:15.51G used_memory_lua:37888 used_memory_lua_human:37.00K used_memory_scripts:0 used_memory_scripts_human:0B number_of_cached_scripts:0 maxmemory:0 maxmemory_human:0B maxmemory_policy:noeviction allocator_frag_ratio:1.20 allocator_frag_bytes:305896 allocator_rss_ratio:4.82 allocator_rss_bytes:6893568 rss_overhead_ratio:1.28 rss_overhead_bytes:2478080 mem_fragmentation_ratio:13.42 mem_fragmentation_bytes:10344864 mem_not_counted_for_evict:0 mem_replication_backlog:0 mem_clients_slaves:0 mem_clients_normal:66616 mem_aof_buffer:0 mem_allocator:jemalloc-5.1.0 active_defrag_running:0 lazyfree_pending_objects:0 # Persistence loading:0 rdb_changes_since_last_save:0 rdb_bgsave_in_progress:0 rdb_last_save_time:1587521698 rdb_last_bgsave_status:ok rdb_last_bgsave_time_sec:-1 rdb_current_bgsave_time_sec:-1 rdb_last_cow_size:0 aof_enabled:1 aof_rewrite_in_progress:0 aof_rewrite_scheduled:0 aof_last_rewrite_time_sec:-1 aof_current_rewrite_time_sec:-1 aof_last_bgrewrite_status:ok aof_last_write_status:ok aof_last_cow_size:0 aof_current_size:0 aof_base_size:0 aof_pending_rewrite:0 aof_buffer_length:0 aof_rewrite_buffer_length:0 aof_pending_bio_fsync:0 aof_delayed_fsync:0 # Stats total_connections_received:3 total_commands_processed:35 instantaneous_ops_per_sec:0 total_net_input_bytes:992 total_net_output_bytes:36972 instantaneous_input_kbps:0.00 instantaneous_output_kbps:0.00 rejected_connections:0 sync_full:0 sync_partial_ok:0 sync_partial_err:0 expired_keys:0 expired_stale_perc:0.00 expired_time_cap_reached_count:0 evicted_keys:0 keyspace_hits:0 keyspace_misses:0 pubsub_channels:0 pubsub_patterns:0 latest_fork_usec:0 migrate_cached_sockets:0 slave_expires_tracked_keys:0 active_defrag_hits:0 active_defrag_misses:0 active_defrag_key_hits:0 active_defrag_key_misses:0 # Replication role:master connected_slaves:0 master_replid:a0468cb6b4456287c809c15b0ea788f4348fe8b9 master_replid2:0000000000000000000000000000000000000000 master_repl_offset:0 second_repl_offset:-1 repl_backlog_active:0 repl_backlog_size:1048576 repl_backlog_first_byte_offset:0 repl_backlog_histlen:0 # CPU used_cpu_sys:0.971191 used_cpu_user:1.097652 used_cpu_sys_children:0.006025 used_cpu_user_children:0.004464 # Cluster cluster_enabled:0 # Keyspace
