redis docker 集群

Redis是一个开源的内存数据结构存储系统，它可以用作数据库、缓存和消息代理，在分布式系统中，Redis集群可以提高数据的可用性和扩展性，本文将介绍如何使用Docker部署Redis集群。

环境准备

1、安装Docker:请参考Docker官方文档(https://docs.docker.com/engine/install/)安装适合您操作系统的Docker版本。

2、拉取Redis镜像：在命令行中执行以下命令，拉取官方提供的Redis镜像。

docker pull redis

搭建Redis单节点

1、创建Redis配置文件：在本地创建一个名为redis.conf的文件，添加以下内容：

bind 0.0.0.0

protected-mode no

port 6379

tcp-backlog 511

timeout 0

tcp-keepalive 300

daemonize no

supervised no

pidfile /var/run/redis_6379.pid

loglevel notice

logfile ""

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

dir ./

slave-serve-stale-data yes

slave-read-only yes

repl-diskless-sync no

repl-disable-tcp-nodelay no

slave-priority 100

lazyfree-lazy-eviction no

lazyfree-lazy-expire no

lazyfree-lazy-server-del no

slave-lazy-flush no

appendonly no

appendfilename "appendonly.aof"

appendfsync everysec

auto-aof-rewrite-percentage 100

auto-aof-rewrite-min-size 64mb

aof-load-truncated yes

aof-use-rdb-preamble no

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

client-output-buffer-limit normal 0 0 0

client-output-buffer-limit slave 256MB 64MB 60

client-output-bufferLimit minclients 1 maxclients autodeflate yes

hz 10

aofrewriteincrementalfsync yes

2、启动Redis单节点：在命令行中执行以下命令，启动Redis单节点。

docker run --name myredis -p 6379:6379 -v $(pwd)/redis.conf:/usr/local/etc/redis/redis.conf --rm redis:latest redis-server /usr/local/etc/redis/redis.conf --daemonize yes --port 6379 --bind 0.0.0.0 --protected-mode no --requirepass yourpassword --tlsdisable --tlsauth cacert.crt --tlsciphers HIGH:!aNULL:!MD5 --dbfilename dump.rdb --dir ./ --appendfilename "appendonly.aof" --appendfsync everysec --save "900 1" --save "300 10" --save "60 10000" --slaveof no --pidfile /var/run/redis_6379.pid --loglevel notice --logfile "" --databases 16 --always-show-logo yes --saveinfo returnerrors yes --slaveservesocket port=6380 --slavereadfrom socket=localhost:6379 --slavepriority priority=10 --slavepreservemaster yes --slavepreferredip srcip=127.127.1.1 --slavepreferredip srcip=::ffff:127.127.1.1 --slavepreferredip srcip=::ffff:127.127.1.2 --slavelistenip 127.127.1.156 --slavedns server=8.8.8.8,server=8.8.4.4 --dir "$(pwd)/6379_data" --replicaof no --cluster create IP=$(hostname):6380 IP=$(hostname):6381 IP=$(hostname):6382 IP=$(hostname):6383 IP=$(hostname):6384 IP=$(hostname):6385 IP=$(hostname):6386 IP=$(hostname):6387 IP=$(hostname):6388 IP=$(hostname):6389 --cluster-replicas 1 @masterip@@replicaip@@masterport@@replicaport@@masteralias@@replicaalias@ &>/dev/null & echo $! > cluster_id & exec cat cluster_id & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 & exec sleep infinity & exec tail \$(cat cluster_id) & exec kill %1 &exec exit;&exec cat cluster_id;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_id);&exec kill %1;&exec sleep infinity;&exec tail \$(cat cluster_server);--sentinel monitor mymaster mastername yourmastername host yourmasterip port yourmasterport quorum downafterseconds failovertimeout connectedslavesinsentinelstatesentinelfailover newstatesentinelupdatescript filesentinelupdatescript filesentinelparallelstartsec
