VMware安装Redis遇到的几个问题

1. bind绑定，默认时127.0.0.1，因为还不确定哪些机器访问，故设置为0.0.0.0
2. 防火墙需要配置一下

   iptables -N REDIS
   iptables -A REDIS -s 192.168.2.13 -j ACCEPT
   iptables -A REDIS -s 192.168.2.14 -j ACCEPT
   iptables -A REDIS -s 192.168.2.12 -j ACCEPT
   iptables -A REDIS -j LOG --log-prefix "unauth-redis-access"
   iptables -A REDIS -j REJECT --reject-with icmp-port-unreachable
   iptables -I INPUT -p tcp --dport 6379 -j REDIS
   iptables -I INPUT -p tcp --dport 6380 -j REDIS

    

3. 集群模式先打开cluster-enabled属性开放出来
4. 建立集群时，节点有数据，先删除数据，包括失败的集群配置
5. 集群节点等待

   开放redis集群总线端口，集群总线端口是redis客户端连接的端口+10000。命令如下

   iptables -I INPUT -p tcp --dport 16379 -j REDIS
   iptables -I INPUT -p tcp --dport 16380 -j REDIS

    

6. redis dir 文件路径会导致启动失败
