我已经遵循了各种脚本来build立2台linode机器。 都有一个外部和本地的IP。 在一个我已经安装了Redis,我想通过本地IP连接到这台机器。
我应该添加哪些规则来允许从其他的linode访问端口6379(redis),但是不能从互联网的其他端口访问?
我的/etc/iptables.firewall.rules到目前为止:
---- *filter # Allow all loopback (lo0) traffic and drop all traffic to 127/8 that doesn't use lo0 -A INPUT -i lo -j ACCEPT -A INPUT -d 127.0.0.0/8 -j REJECT # Accept all established inbound connections -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # Allow all outbound traffic - you can modify this to only allow certain traffic -A OUTPUT -j ACCEPT # Allow HTTP and HTTPS connections from anywhere (the normal ports for websites and SSL). -A INPUT -p tcp --dport 80 -j ACCEPT -A INPUT -p tcp --dport 443 -j ACCEPT # Allow SSH connections # # The -dport number should be the same port number you set in sshd_config # -A INPUT -p tcp -m state --state NEW --dport 22 -j ACCEPT # Allow ping -A INPUT -p icmp --icmp-type echo-request -j ACCEPT # Log iptables denied calls -A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7 # Drop all other inbound - default deny unless explicitly allowed policy -A INPUT -j DROP -A FORWARD -j DROP
在-A INPUT -j DROP规则之前的某个位置包含此规则:
-A INPUT -s 123.45.67.8 -p tcp -m state --state NEW --dport 6379 -j ACCEPT
将123.45.67.8更改为您希望允许访问的服务器的IP地址。
