問題描述：
??????? 在Centos服務器上裝好Redis緩存服務后，其他機器訪問不了，提示連接超時。,郁悶,在網上找到解決方案：
??? /sbin/iptables?-I?INPUT?-p?tcp?--dport?6379 ?-j?ACCEPT
???? /sbin/iptables?-I?INPUT?-p?tcp?--dport?6380 -j?ACCEPT
然后保存：
??? /etc/rc.d/init.d/iptables?save
這樣重啟計算機后,CentOS防火墻默認已經開放了6379和6380端口。
這里應該也可以不重啟計算機：
??? /etc/init.d/iptables?restart
?
查看CentOS防火墻信息：
??? /etc/init.d/iptables?status
關閉CentOS防火墻服務：
??? /etc/init.d/iptables?stop
永久關閉：
?? chkconfig?–level?35?iptables?off
