Hi
You can set up VM startup on the Host configuration Tab - "Virtual Machine Startup/Shutdown" setting
The setting will follow the VM to other hosts
I must inform also that these settings becomes/are disabled when the host join/is part of an HA cluster
You could disable HA and set this up before you shut down the whole environment, but I would do the following:
Move vCenter to a specific host (ESXi 001)
Disable DRS on for the vCenter VM so that you always know where it is in future, unless that host fails and HA will move it.
Shut down all VMs accept vCenter
Shut down all Hosts accept (ESX 001)
Connect straight to (ESX 001) with vSphere client
Shut down vCenter VM
Shut Down Host
Starting Up:
Start all Host (ESX 001) 1st
Connect to (ESX 001) with vSphere client
Start vCenter VM
Connect to vCenter
Start all VMs
Just to note, when all VMs are gracefully shut down and a host restarts, the VM will not be started because th3e last state was powered off
(This is for an HA cluster off course 
)
Please award points if you find this helpful/correct 
So to answer your question
When i will restart the esx, i want the vcenter vm to start automaticaly, is it possible ?
If it is an HA cluster = NO not possible
If it is a normal Cluster = Yes through host settings "Virtual Machine Startup/Shutdown"
