mongo连接不上Timed out after 30000

本地连接mongo报错，错误代码为：

Caused by: com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting for a server that matches WritableServerSelector. Client view of cluster state is {type=UNKNOWN, servers= ...............................

Caused by: com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting for a server that matches WritableServerSelector. Client view of cluster state is {type=UNKNOWN, servers= ...............................

系统：

　　centos7， 64位

　　mongo，mongodb-linux-x86_64-rhel70-4.0.10

解压，进入bin，启动

./mongod --dbpath=/data/db/ --config=./mongodb.conf &

./mongod --dbpath=/data/db/ --config=./mongodb.conf &

报错了

为什么呢？

用linux本地连接mongo测试 --》 是ok的，证明服务没有问题

那是什么呢？--》防火墙

[root@localhost data]# systemctl stop firewalld.service #停止firewall
[root@localhost data]# systemctl disable firewalld.service #禁止firewall开机启动
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.

搞定ok！！！！
