# 连接redis集群

# 任何一个都行
cd 7001

# ./redis-cli -h xxx -p xxx -c

./redis-cli -p 7001 -c

重装: 先关闭6个节点, 将6个节点中, 任何一个节点的三个文件都删除掉(*.rdb,*.aof,nodes.conf)

redis能用shell脚本

/usr/local/redis-cluster/7001/redis-cli -p 7001 -c --raw hdel content 89

mac os sed 扩展正则表达式, 和GNU不一样…

由于mac系统是原生于bsd系，sed命令和gnu不同

mac sed 正则表达式竟然不能用+号

还得使用扩展参数…略坑…-E

echo "foobar" | sed -E -e "s/o+//"

mac自带的sed和linux表现不一致， 需要安装gnu-sed
