1.添加镜像
# docker pull redis:4.0
2.在/data下新建文件夹redis，进入redis文件夹新建文件夹conf4.0
# mkdir /data # mkdir /data/redis/conf4.0
3.创建并写入 redis.conf
# vim /data/redis/conf4.0/redis.conf
内容
bind 0.0.0.0
# 端口
port 6379
# 持久化
appendonly yes
requirepass password
4.执行命令启动
# docker run -d -ti -p 6379:6379 --net docker_default -v /data/redis/conf4.0/redis.conf:/usr/local/etc/redis/redis.conf -v /data/redis/data:/data --restart always --name redis4.0 --sysctl net.core.somaxconn=1024 redis redis-server /usr/local/etc/redis/redis.conf
5.执行命令解说
1、-p是指启动的端口 2、第二行指定了配置的位置，命令指的是刚刚复制的配置，配置中有端口、密码等重要参数 3、第三行开始的是指定数据存储位置，--restart always是自动重启，--name redis4.0设置容器的名字为redis4.0 4、第四行设置tcp内核参数，默认512 5、启动镜像名和服务、配置（固定不能变）
6.简单操作
[root@localhost conf4.0]# docker run -it redis:4.0 redis-cli -h 172.17.0.1 -p 6379 -a password 172.17.0.1:6379> info # Server redis_version:4.0.10 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:5df2417984e896d3 redis_mode:standalone os:Linux 3.10.0-862.3.3.el7.x86_64 x86_64 arch_bits:64 multiplexing_api:epoll atomicvar_api:atomic-builtin gcc_version:6.3.0 process_id:1 run_id:facf14d5495779acb1e50c574d7479fd89c9dfe7 tcp_port:6379 uptime_in_seconds:527 uptime_in_days:0 hz:10 lru_clock:3506205 executable:/data/redis-server config_file:/usr/local/etc/redis/redis.conf # Clients connected_clients:1 client_longest_output_list:0 client_biggest_input_buf:0 blocked_clients:0 # Memory used_memory:849384 used_memory_human:829.48K used_memory_rss:8159232 used_memory_rss_human:7.78M used_memory_peak:849384 used_memory_peak_human:829.48K used_memory_peak_perc:100.12% used_memory_overhead:836150 used_memory_startup:786520 used_memory_dataset:13234 used_memory_dataset_perc:21.05% total_system_memory:1910042624 total_system_memory_human:1.78G used_memory_lua:37888 used_memory_lua_human:37.00K maxmemory:0 maxmemory_human:0B maxmemory_policy:noeviction mem_fragmentation_ratio:9.60 mem_allocator:jemalloc-4.0.3 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:1530232334 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:1 total_commands_processed:2 instantaneous_ops_per_sec:0 total_net_input_bytes:59 total_net_output_bytes:10168 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:42f75f1fc5e74d69b502af5af925870b8ffceaf6 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:0.44 used_cpu_user:0.17 used_cpu_sys_children:0.01 used_cpu_user_children:0.00 # Cluster cluster_enabled:0 # Keyspace
