本地构建一个Redis Cluster调试集群

有时候，我们需要调试redis cluster的一些功能，我们需要在本地搭建
首先，先本地安装一个Redis，并且搞一个配置文件如下
命名为redis.conf，把它放在某个目录（比如说~/rc）的下面

bind 0.0.0.0
protected-mode yes
port 6380
tcp-backlog 511
timeout 0
tcp-keepalive 300
daemonize yes
supervised no
pidfile /var/run/redis_6380.pid
loglevel notice
logfile "logs/redis_6380.log"
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 data/6380
replica-serve-stale-data yes
replica-read-only yes
repl-diskless-sync no
repl-diskless-sync-delay 5
repl-disable-tcp-nodelay no
replica-priority 100
requirepass Su1m2Ab&kPB0J#
masterauth Su1m2Ab&kPB0J#
lazyfree-lazy-eviction no
lazyfree-lazy-expire no
lazyfree-lazy-server-del no
replica-lazy-flush no
appendonly yes
appendfilename "appendonly.aof"
appendfsync everysec
no-appendfsync-on-rewrite no
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb
aof-load-truncated yes
aof-use-rdb-preamble yes
lua-time-limit 5000
cluster-enabled yes
cluster-config-file nodes-6380.conf
cluster-node-timeout 15000
slowlog-log-slower-than 10000
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
stream-node-max-bytes 4096
stream-node-max-entries 100
activerehashing yes
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit replica 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60
hz 10
dynamic-hz yes
aof-rewrite-incremental-fsync yes
rdb-save-incremental-fsync yes

来到这个目录下面，搞点事情

if [ ! -d "data" ]; then mkdir data;fi;if [ ! -d "conf" ]; then mkdir conf;fi;if [ ! -d "logs" ]; then  mkdir logs; fi;for i in `seq 6380 6385`;do mkdir data/$i;cp -rvf redis.conf conf/redis_$i.conf;sed -i "s@6380@$i@g" conf/redis_$i.conf;redis5-server conf/redis_$i.conf;done

这个命令如果也可以写一个shell脚本

if [ ! -d "data" ]; then
        mkdir data;
fi;
if [ ! -d "conf" ]; then
        mkdir conf;
fi;
if [ ! -d "logs" ]; then
        mkdir logs;
fi;
for i in `seq 6380 6385`;
do 
mkdir data/$i;
cp -rvf redis.conf conf/redis_$i.conf;
sed -i "s@6380@$i@g" conf/redis_$i.conf;
redis5-server conf/redis_$i.conf;
done

这样我们瞬间启动了六个redis，现在来把她们加入集群把

redis5-cli -a 'Su1m2Ab&kPB0J#' --cluster create 127.0.0.1:6380 127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384 127.0.0.1:6385 --cluster-replicas 1
