首次運行報錯：connectTimeOut連接數據庫超時，檢查了一下，虛擬機中centos7的Redis的端口被防火墻過濾了。

解決方法：

1.將6379端口加入白名單

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

紅色字部分為新加入的部分，即

-A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT

2.重啟服務

service iptables restart

3.Windows的cmd打開,測試192.168.1.107的6379端口

telnet 192.168.1.107 6379

如果顯示連接成功，--->END

如果顯示連接失敗，請繼續往下看步驟4

4.檢查192.168.1.107中Redis的配置文件

vi redis.conf

找到bind 127.0.0.1修改為192.168.1.107。

再次回到步驟3，測試成功-->END

正在學習Redis，記作筆記，有誤請指出。謝謝
