Manual installation of OpenStack Based on CentOS 6.8

Manual installation of OpenStack Based on CentOS 6.8

1 Environment
1.1 host network

1.1.1 System Architecture
1) nodes are divided into control nodes, computing nodes, block storage nodes, and object storage nodes.
2) All management networks (10.168.0.0/24) and virtual networks use private network addresses to connect to a shared network (Internet 203.0.113.x/8)
3) The physical network and virtual network (non-10.168.0.0/24 segments) should be in different network segments
4) the gateway address in the NAT architecture is 10.168.0.1.
5) Physical nodes use NAT to maintain Time Synchronization
1.1.2 deployment information
1) Control Node
Hostname = rodm.bkjia.org
Ip address = 10.168.0.125
OS = CentOS 6.8

2) computing nodes
Hostname = rod0 [1-2] .bkjia.org
Ip address = 10.168.0. [126-127]
OS = CentOS 6.8
1.1.3 Name Service (optional)
Vim/etc/hosts

Enter the following information:
123 10.168.0.125 rodm.bkjia.com
10.168.0.126 rod01.bkjia.com
10.168.0.127 rod02.bkjia.org

1.2 Security

1.2.1 install the following Password

RABBIT_PASS	Password of user guest of RabbitMQ
SWIFT_PASS	Password of Object Storage service user swift

1.2.2 deploy with a random password
Openssl rand-hex 10

Note: The above command can generate the random password required for the 2.1 Table
1.3 Network Time Protocol

1.3.1 Control Node

1) install the chrony service in yum
Yum install-y chrony

2) configure the chrony Service
Vim/etc/chrony. conf

Modify the synchronized ntp address
Server ntp 10.168.0.x iburst

Note: Intranet NTP servers or Internet NTP servers (in fact, by default)
3) allow non-control nodes to access the ntp service
Vim/etc/chrony. conf
Modify the synchronized ntp address
Allow 10.168.0.0/24

4) Start the NTP service
Chkconfig chronyd on
/Etc/init. d/chronyd start

1.3.2 other nodes
1) install the chrony service in yum
Yum install-y chrony

2) configure the chrony Service
Vim/etc/chrony. conf

Modify as follows:
# Server 0.rhel.pool.ntp.org iburst
# Server 1.rhel.pool.ntp.org iburst
# Server 2.rhel.pool.ntp.org iburst
# Server 3.rhel.pool.ntp.org iburst
Server 10.168.0.125 iburst

3) Start the NTP service
Centos6:
Chkconfig chronyd on
/Etc/init. d/chronyd start

Centos7:
Systemctl enable chronyd. service
Systemctl start chronyd. service
