3.mongo常见操作
# #####read client
# client = pymongo.MongoReplicaSetClient(['172.31.46.25:27017,172.31.43.36:27017,172.31.40.242:27017'],replicaset='shard1')
# db = client.get_database("collection")
# db.authenticate('collection', '78hRdJEnJcHRb4qA')
#
# print db.client.read_preference
# print db.client.primary
# print db.client.secondaries
# print db.client.arbiters
# print db.command('ismaster')
#####read client
client = pymongo.MongoClient(['172.31.32.223:20000'])
db = client.get_database("admin")
db.authenticate('admin', 'ggxP6tPI971K3W0r')
# print db.client.read_preference
# print db.client.primary
# print db.client.secondaries
# print db.client.arbiters
# print db.client.is_primary
# print db.command('ismaster')
# print db.command('currentOp')
# print db.command('replSetGetStatus')
# print db.list_collection_names()
statement=client.collection.get_collection('statement') ###获取对应db下的对应集合
print statement.count()
# client.collection.add_user('newTestUser', 'Test123', roles=[{'role':'readWrite','db':'collection'}]) ####添加用户
# client.collection.remove_user('newTestUser') ####删除用户
db2 = client.get_database("collection")
db2.add_user('newTestUser', 'Test123', roles=[{'role':'readWrite','db':'collection'}]) ###添加用户
print db.current_op()
# options = {'lock': True}
# db.client.fsync(**options)
# print db.client.is_locked
# ####
# print db.command('fsyncUnlock')
# print db.client.is_locked
