mongodb通过socket链接

mongodb默认绑定ip：127.0.0.1

但是一旦设定其他ip，即使设定nounixsocket 为false，也无法生成mongodb-27017.sock文件，也即无法通过socket链接访问服务mongod。

MongoDB, by default, creates a unix socket at /tmp/mongodb-27017.sock as of pymongo 2.4. You can make a connection like this:

from pymongo import MongoClientCONNECTION = MongoClient('/tmp/mongodb-27017.sock')

Additionally you can disable this behavior by starting mongod with --nounixsocket or specify an alternate location with --unixSocketPrefix <path>

MongoDB will always create and listen on a UNIX socket, unless --nounixsocket is set, --bind_ip is not set, or --bind_ip specifies 127.0.0.1.
