我在连接到我的mongo shell时遇到问题。当我从IPTables中删除所有指令时，我可以成功连接。 CentOS 6.5，mongod正在运行。这是我得到的错误：
[samir@core ~]$ mongo 127.0.0.1:27017
MongoDB shell version: 2.4.9
connecting to: 127.0.0.1:27017/test
Wed Mar 12 00:42:12.193 Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:147
exception: connect failed
我也尝试从mongo开始。
Mongod正在运行：
[samir@core ~]$ sudo service mongod start
Starting mongod: about to fork child process, waiting until server is ready for connections.
forked process: 2104
all output going to: /var/log/mongo/mongod.log
child process started successfully, parent exiting
[ OK ]
mongo日志没有任何指向：

我的IPTables看起来像这样：
Chain INPUT (policy DROP 49 packets, 3315 bytes)
pkts bytes target prot opt in out source destination
1665 130K ACCEPT all -- eth0 any anywhere anywhere state RELATED,ESTABLISHED
2 128 ACCEPT tcp -- any any anywhere anywhere tcp dpt:ssh
0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:http
0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:https
18 1080 ACCEPT tcp -- any any anywhere anywhere tcp dpt:27017
0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:28017
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 987 packets, 156K bytes)
pkts bytes target prot opt in out source destination
如果我将INPUT指令设置为ACCEPT，则mongo shell可以工作：
[samir@core db]$ sudo mongo
MongoDB shell version: 2.4.9
connecting to: test

Netstat -pln |代表27017：
[samir@core db]$ sudo netstat -pln | grep 27017

我的iptables输入政策肯定有问题。有什么想法吗？
答案 0 :(得分：1)
您可能想尝试替换
行iptables -A INPUT -s 127.0.0.1 -j ACCEPT
使用
iptables -A INPUT -i lo -j ACCEPT
