mongo鏈接不上Timed out after 30000

 

 

 

 

本地鏈接mongo報錯，錯誤代碼爲：

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= ...............................

 

系統： 

　　centos7， 64位

　　mongo，mongodb-linux-x86_64-rhel70-4.0.10

解壓，進入bin，啓動

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

 

報錯了

 

爲何呢？

用linux本地鏈接mongo測試 --》 是ok的，證實服務沒有問題

 

那是什麼呢？--》防火牆

 

[root@localhost data]# systemctl stop firewalld.service #中止firewall
[root@localhost data]# systemctl disable firewalld.service #禁止firewall開機啓動
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost data]# 

搞定ok！！！！
