OpenStack Installation Configuration

First, pre-installation preparation

Installing OpenStack Liberty on the RHEL7/CENTOS7

Two virtual machines, install the CENTOS7 system (prepare two network cards, one NAT, the other host only)

NAT network card set IP, can be networked, only the host's network card as long as we can access the windows, mainly with Putty remote connection

Turn off SELinux

Close Iptables

Systemctl Stop Firewalld

Systemctl Disable FIREWALLD

Close NetworkManager

Systemctl Stop NetworkManager

Systemctl Disable NetworkManager

Second, the configuration password

Passwords are used in multiple places during the deployment of OpenStack, and in order to facilitate administration and security settings, we need to define the password in advance and use the command Mkpasswd-s 0 to generate a random string

Database password (no variable used)Root password for the database Tn1pi6ytm

Admin_passPassword of user admin 3qivpzu2x

Ceilometer_dbpassDatabase password for the Telemetry service CZN3BF1HM

Ceilometer_passPassword of Telemetry service user Ceilometer Abquh12gu

Cinder_dbpassDatabase password for the Block Storage service o3bwbpoz3

Cinder_passPassword of Block Storage service user CINDER Hf8lx9bow

Dash_dbpassDatabase password for the dashboard 5qbzxnn1g

Demo_passPassword of user demo 9ttbgaa1q

Glance_dbpassDatabase password for Image service zznky4tp0

Glance_passPassword of Image service user GLANCE Wuyaf4cv6

Heat_dbpassDatabase password for the Orchestration service B7FK5WJLG

Heat_domain_passPassword of Orchestration DOMAIN 7gotb3eoh

Heat_passPassword of Orchestration service user HEAT eqq2jlgz0

Keystone_dbpassDatabase password of Identity service f6zx0gurv

Neutron_dbpassDatabase password for the Networking service quidyOC50

Neutron_passPassword of Networking service user NEUTRON mdcgvl29i

Nova_dbpassDatabase password for Compute service rygv0rg7p

Nova_passPassword of Compute service user Nova HsSNsqc43

Rabbit_passPassword of user guest of RabbitMQ O3NXOVNZ5

Swift_passPassword of Object Storage service user Swift 6CI5XWODK

Metadata_secret M8UHMQTU2

Third, configure the IP (a NAT mode, a host-only mode, only the host network card only need to connect to the Xshell)

On the controler.

Dhclient eno16777736 (NAT card)

Dhclient-r

Dhclient Eno 33554984 (host card only)

Ifconfig View IP

vim/etc/sysconfig/network-scripts/ifcfg-eno16777736

Type=ethernet

Bootproto=static

Defroute=yes

Ipv4_failure_fatal=no

name=eno16777736

Uuid=6612a6a5-090b-43b8-9c87-e43545f800a9

Onboot=yes

ipaddr=192.168.163.249

Prefix=24

gateway=192.168.163.2

Peerdns=no

On the computer.

Dhclient eno16777736 (NAT card)

Dhclient-r

Dhclient Eno 33554984 (host card only)

Ifconfig View IP

vim/etc/sysconfig/network-scripts/ifcfg-eno16777736

Vim/etc/resolv.conf

Four, two machines, set hostname, configure time synchronization

HOSTNAMECTL Set-hostname Controller

Hostnamectl Set-hostname Computer

Edit/etc/hosts:192.168.163.249 Controller

192.168.163.246 Computer

Controller on:

Yum Install-y chrony

Vi/etc/chrony.conf

Add or change: Allow 192.168.163.0/24

After saving, execute Systemctl enable Chronyd.service

Systemctl Start Chronyd.service

On COMPUTE:

Yum Install-y chrony;vi/etc/chrony.conf

Add or change: Server controller Iburst

After saving, execute Systemctl enable Chronyd.service

Systemctl Start Chronyd.service

V. Configuring the Yun source upgrade software to install the packages required by OpenStack

Install OpenStack's Yum Source (operates on two machines)

Yum Install-y Centos-release-openstack-liberty

Upgrade all packages (operate on two machines)

Yum Upgrade

Restart the system after the end

Installing the OpenStack client and Openstack-selinux

Yum install-y python-openstackclient Openstack-selinux

VI. Installing SQL Services (Controler)

Yum install-y mariadb mariadb-server Mysql-python

Edit Profile VI/ETC/MY.CNF.D/MARIADB_OPENSTACK.CNF//Add to the content below

[Mysqld]

Bind-address = 192.168.163.249

Default-storage-engine = InnoDB

Innodb_file_per_table #表示一个表对应一个文件

Collation-server = Utf8_general_ci

Init-connect = ' SET NAMES UTF8 '

Character-set-server = UTF8

Start Mariadb:systemctl Enable Mariadb.service

Systemctl Start Mariadb.service

Security configuration, setting the root password

Mysql_secure_installation

Set the root password to Tn1pi6ytm #此处密码为第二步用mkpasswd生成的密码

All you need to determine is Y.

Use Mysql-uroot-ptn1pi6ytm to test if you can log in

Vii. install NoSQL (Control) If the schema does not need to be installed

NoSQL databases are used by telemetry service to

Here we are installing MongoDB

Yum install-y mongodb-server MongoDB

Edit the configuration file vi/etc/mongod.conf//change the configuration as follows

BIND_IP = 192.168.163.249

Smallfiles = True

Start the service

Systemctl Enable Mongod.service

Systemctl Start Mongod.service

VIII. Installing Message Queuing (controler)

The RABBITMQ Message Queuing service plays a critical role in OpenStack, as it is a transport hub, where communication between components is done.

Yum Install-y rabbitmq-server

Start the Rabbitmq-server service

Systemctl Enable Rabbitmq-server

Systemctl Start Rabbitmq-server

Use PS aux |grep rabbitmg and NETSTAT-LNP |grep 5672 to determine if there is a boot

Add OpenStack Users

Rabbitmqctl Add_user OpenStack O3nxovnz5

Password O3NXOVNZ5 user name is OpenStack

Licensing for OpenStack Users

Rabbitmqctl set_permissions OpenStack ". *" ". *" ". *"

Allow OpenStack users to be configurable, writable, readable
