How to quickly deploy multiple nodes in openstack
This article mainly introduces how to quickly deploy multi-nodes in openstack. It is very detailed and has a certain reference value. Friends who are interested must finish it!
Install the CentOS6 operating system
Use floppy disk pass to burn and write the downloaded image, set the server to U disk to start and install.
Configure the network
At the control node
Cd / etc/sysconfig/network-scriptsvim ifcfg-eth0
After modification (public network)
Cat ifcfg-eth0 DEVICE=eth0TYPE=Ethernet BOOTPROTO=staticHWADDR=00:0C:29:13:D1:6FONBOOT=yesIPADDR=x.x.x.xGATEWAY=x.x.x.xDNS1=114.114.114.114 DNS2=8.8.8.8
Configure private network
Cd / etc/sysconfig/networ-scrriptsvim ifcfg-eth2
After the modification
Cat ifcfg-eth2 DEVICE=eth2TYPE=Ethernet BOOTPROTO=none HWADDR=00:0C:29:56:8CONBOOT=yes IPADDR=x.x.x.x NETMASK=255.255.255.0
Restart the network
Service network restart
Computing node
Except for the IP address, the rest are exactly the same as the control node (the MAC address is automatically assigned by the system and does not need to be modified)
Replacement network easy to open source (increase speed)
Cd / etc/yum.repos.dyum install-y wget wget http://mirrors.163.com/.help/CentOS6-Base-163.repo mv CentOS-Base.repo CentOS-Base.repo.bakmv CentOS6-Base-163.repo CentOS-Base.repo
Install the RDO source and EPEL remote data deployment package
Yum install-y epel-release-6-8.noarch.rpmyum install-y openstack-icehouse/rdo-release-icehouse-4.noarch.rpm
Note 1: because the URL cannot be added to the code, the correct path is http://mirrors.zju.edu.cn/epel//6/x86_64/epel-release-6-8.noarch.rpm
Note the correct address of the 2:rdo remote data deployment package is https://repos.fedorapeople.org/repos/openstack/openstack-icehouse/rdo-release-icehouse-4.noarch.rpm
Create a yum cache
Yum clean allyum makecache yum update-yreboot-p
Note: execute the same command on the compute node
Installation file settings
Yum install-y openstack-packstack (both control node and compute node need to be executed)
Generate a configuration file (at the control node)
Packstack-gen-answer-file=myanswer.txt
Modify the following in the file
CONFIG_NOVA_COMPUTE_PRIVIF=eth2 CONFIG_NOVA_NETWORK_PRIVIF=eth2 CONFIG_COMPUTE_HOSTS=x.x.x.x (compute node ip) CONFIG_NETWORK_HOSTS=x.x.x.x (controller node ip)
Get rid of demo test network and users
CONFIG_PROVISION_DEMO=n
Start installation
Packstack-answer-file=myanswer.txt
Note: an ERROR error may occur midway, which is due to network reasons, just run the above command again.
