i already did,
i create multichain on my vagrant.
is always show:
IO error: lock /home/vagrant/.multichain/chain1/permissions.db/LOCK: Resource temporarily unavailable

ERROR: Couldn't initialize permission database for blockchain chain1. Probably multichaind for this blockchain is already running. Exiting...

i still not found how to solve this,

It sounds like you are trying to run two copies of MultiChain on the same server, using the same blockchain directory. This is not allowed.

i just only have 1 chain project,
coz the 1st project i installed already removed.

and how can i fix this:
IO error: lock /home/vagrant/.multichain/chain1/permissions.db/LOCK: Resource temporarily unavailable

and this:
ERROR: Couldn't initialize permission database for blockchain chain1

Please confirm using a process monitor (such as ps -x in Linux) that a copy of MultiChain is not already running on this system.
