Shortly after I first came into contact with openstack, I encountered some problems when implementing 3-node deployment by referring to the official documentation, mainly focusing on the compute node. Fortunately, I had more than a decade of O M experience to help me solve the problem one by one. The solution is marked in red.
System Environment: centos 6.5 64-bit
IP addresses of each node: configured according to the IP addresses in the official documentation.
