問(wèn)題描述：
??????? 在Centos服務(wù)器上裝好Redis緩存服務(wù)后，其他機(jī)器訪問(wèn)不了，提示連接超時(shí)。,郁悶,在網(wǎng)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(jì)算機(jī)后,CentOS防火墻默認(rèn)已經(jīng)開(kāi)放了6379和6380端口。
這里應(yīng)該也可以不重啟計(jì)算機(jī)：
??? /etc/init.d/iptables?restart
?
查看CentOS防火墻信息：
??? /etc/init.d/iptables?status
關(guān)閉CentOS防火墻服務(wù)：
??? /etc/init.d/iptables?stop
永久關(guān)閉：
?? chkconfig?–level?35?iptables?off
