I deploy openstack architecture with openstack networking(neutron) according to offcial document icehouse step by step. When I try to add networking service on network node (to configure ml2 plugin), the system prompts me to install a database while I have already had MySQL on controller node. Maybe there exists some problems on connecting to database on controller node.

Following are the prompt information in configureing neutron-common: An error occured while installing the database:

Error 2002 (HY000): can't connect to local MySQL server through socket 'var/run/mysqld/mysqld.sock'

On Controller :-

[root@icehouse1 ~(keystone_admin)]# iptables-save | grep mysql
-A INPUT -s -p tcp -m multiport --dports 3306 -m comment --comment "001 mysql incoming mysql_192.168.1.127" -j ACCEPT
-A INPUT -s -p tcp -m multiport --dports 3306 -m comment --comment "001 mysql incoming mysql_192.168.1.137" -j ACCEPT
[root@icehouse1 ~(keystone_admin)]# netstat -lntp | grep 3306
tcp        0      0  *               LISTEN      3815/mysqld

thank you for your comments, dbaxps! I've solved my problem that MySQL server on controller node can't allow remote connection. I configure MySQL by allowing remote connection from network node and compute node1.
