一、安装redis
略

二、主节点配置文件

daemonize yes
pidfile /usr/local/redis/logs/redis_6379.pid
port 6379
tcp-backlog 1024
bind 0.0.0.0
timeout 0
tcp-keepalive 60
loglevel notice
logfile "/usr/local/redis/logs/redis_6379.log"

databases 16

save ""

save 900 1

save 300 10

save 60 10000

stop-writes-on-bgsave-error yes

rdbcompression yes
rdbchecksum yes

dbfilename dump.rdb
dir /usr/local/redis/data/

如果做故障切换，不论主从节点都要填写密码且要保持一致

masterauth linlin

slave-serve-stale-data yes
slave-read-only yes
repl-disable-tcp-nodelay no
slave-priority 100

requirepass linlin

appendonly yes
appendfilename "appendonly.aof"

appendfsync always

appendfsync everysec

appendfsync no

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-log-slower-than 1000
slowlog-max-len 1000

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

三、从节点配置文件

只需要复制主节点配置，增加slaveof xxx
修改6379端口 使用 sed -i 's/6379/6380/g' 6380.conf就可以

daemonize yes
pidfile /usr/local/redis/logs/redis_6380.pid
port 6380
tcp-backlog 1024
bind 0.0.0.0
timeout 0
tcp-keepalive 60
loglevel notice
logfile "/usr/local/redis/logs/redis_6380.log"

databases 16

save ""

save 900 1

save 300 10

save 60 10000

stop-writes-on-bgsave-error yes

rdbcompression yes
rdbchecksum yes

dbfilename dump.rdb
dir /usr/local/redis/data/

slaveof 10.211.55.7 6379

如果做故障切换，不论主从节点都要填写密码且要保持一致

masterauth linlin

slave-serve-stale-data yes
slave-read-only yes
repl-disable-tcp-nodelay no
slave-priority 100

requirepass linlin

appendonly yes
appendfilename "appendonly.aof"

appendfsync always

appendfsync everysec

appendfsync no

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-log-slower-than 1000
slowlog-max-len 1000

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

四、同上配置6381节点的配置文件

五、启动
主节点启动
./redis-server 6379.conf
会报logs文件夹不存在
可以使用 mkdir -p /usr/local/xxx/logs 完成logs文件夹的创建
可以使用 mkdir -p /usr/local/xxx/data完成data文件夹的创建
./redis-server 6380.conf
./redis-server 6381.conf

六、启动完毕后查看 redis集群
./redis-cli -p 6379 -a xxx密码 info replication
