Deploy a complete set of mongo shard servers

• 3 mongos
• 3 shardsvr, One master and two slaves
• 1 configsvr, One master and two slaves

sehema.py

configsvr_define configsvr : Linux server address configuration information shardsvr_define : 3 groups of shardsvr, each group is one master and two slaves mongos_define : Deploy 3 mongos processes servers linux : linux server ip, port, pwd root : root path

Example: start: python deploy.py --start --project test close: python deploy.py --close --project test

test mongo:

mongo --host 192.168.0.100 --port 3201
