首次运行报错：connectTimeOut连接数据库超时，检查了一下，虚拟机中centos7的Redis的端口被防火墙过滤了。
解决方法：
1.将6379端口加入白名单
vi /etc/sysconfig/iptables
# sample configuration for iptables service # you can edit this manually or use system-config-firewall # please do not ask us to add additional ports/services to this default configuration *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT
红色字部分为新加入的部分，即
-A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT
2.重启服务
service iptables restart
3.Windows的cmd打开,测试192.168.1.107的6379端口
telnet 192.168.1.107 6379
如果显示连接成功，--->END
如果显示连接失败，请继续往下看步骤4
4.检查192.168.1.107中Redis的配置文件
vi redis.conf
找到bind 127.0.0.1修改为192.168.1.107。
再次回到步骤3，测试成功-->END
正在学习Redis，记作笔记，有误请指出。谢谢
