redis集群搭建

目标在三台机器上搭建三主三从的集群，每个主对应一个从

ip：192.168.192.133 192.168.192.139 192.168.192.189

1，在每个机器上安装redis

mkdir -p /home/soft/download-package/
cd /home/soft/download-package/
wget https://download.redis.io/releases/redis-6.2.1.tar.gz
tar -zxvf redis-6.2.1.tar.gz
mv redis-6.2.1 /usr/local
cd  /usr/local/redis-6.2.1
make
make install PREFIX=/usr/local/redis-6.2.1

2，每个机器上新建集群文件夹，其它2个机器 为 20003 20004 20005 20006 

mkdir cluster
cd cluster
mkdir 20001
mkdir 20002

3，生成配置文件 

daemonize yes

pidfile /usr/local/redis-6.2.1/cluster/20001/20001.pid

port 20001 


tcp-backlog 511


bind 0.0.0.0

timeout 0

tcp-keepalive 0

loglevel notice

logfile "20001.log"

databases 16

save 900 1
save 300 10
save 60 10000

stop-writes-on-bgsave-error yes

rdbcompression yes

rdbchecksum yes

dbfilename 20001.rdb

dir /usr/local/redis-6.2.1/cluster/20001

slave-serve-stale-data yes

slave-read-only yes

repl-diskless-sync no

repl-diskless-sync-delay 5

repl-disable-tcp-nodelay no

slave-priority 100

masterauth mypasswd
requirepass mypasswd

appendonly yes

appendfilename "20001.aof"

appendfsync everysec

no-appendfsync-on-rewrite no

auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb

aof-load-truncated yes

lua-time-limit 5000

slowlog-max-len 128

latency-monitor-threshold 0

notify-keyspace-events ""

hash-max-ziplist-entries 512
hash-max-ziplist-value 64

list-max-ziplist-entries 512
list-max-ziplist-value 64

set-max-intset-entries 512

zset-max-ziplist-entries 128
zset-max-ziplist-value 64

hll-sparse-max-bytes 3000

activerehashing yes

client-output-buffer-limit normal 0 0 0
client-output-buffer-limit slave 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60

hz 10

aof-rewrite-incremental-fsync yes

# 是否开启集群
cluster-enabled yes
# 集群配置文件（启动后自动生成）
cluster-config-file nodes-20001.conf
# 集群节点ping、pong超时时间
cluster-node-timeout 5000

配置文件拷贝到其它节点，执行下面的命令替换文件中的内容，最后生成6个文件

sed -i 's/20001/20003/g' /usr/local/redis-6.2.1/cluster/20003/redis.conf

 

4，在三个机器上启动6个节点

/usr/local/redis-6.2.1/src/redis-server /usr/local/redis-6.2.1/cluster/20001/redis.conf

 

5，创建集群

 /usr/local/redis-6.2.1/src/redis-cli --cluster create -a mypasswd 192.168.192.133:20001 192.168.192.139:20003 192.168.192.189:20005 192.168.192.139:20004 192.168.192.189:20006 192.168.192.133:20002 --cluster-replicas 1

 

6，查看集群状态

 /usr/local/redis-6.2.1/src/redis-cli -h 192.168.192.133 -a mypasswd -p 20001 cluster nodes

出现如下结果说明集群搭建成功了
