OpenStack Build Prep Work

1. Host name and server IP address

Controller 192.168.23.98 (Control node) compute1 192.168.23.61 (Compute node)

2. Configuring the Hosts resolution

[[email protected] ~]# vim/etc/hosts add 192.168.23.98 controller192.168.23.61 compute1[[email protected] ~]# scp/etc/ hosts [email protected]:/etc/hosts to ensure that the hosts file for each node is unified

3. Verification

[Email protected] ~]# ping-c 4 compute1ping compute1 (192.168.23.61) (+) bytes of data.64 bytes from compute1 (192.16 8.23.61): icmp_seq=1 ttl=64 time=0.639 ms64 bytes from compute1 (192.168.23.61): icmp_seq=2 ttl=64 time=0.307 ms64 bytes F Rom compute1 (192.168.23.61): icmp_seq=3 ttl=64 time=0.324 ms64 bytes from compute1 (192.168.23.61): Icmp_seq=4 ttl=64 Tim e=0.312 ms---compute1 PING statistics---4 packets transmitted, 4 received, 0% packet loss, time 3000msrtt MIN/AVG/MAX/MD EV = 0.307/0.395/0.639/0.142 ms

5. Turn off Selinx and firewall firewalld

The following command all nodes Execute # sed-i ' s/selinux=enforcing/selinux=disabled/g '/etc/selinux/config# setenforce 0# systemctl Stop                 firewalld.service# systemctl Disable firewalld.service# reboot# sestatus–v Check if successful SELinux status is turned off: Disabled

4. Configure the time synchronization server (NTP)

Control Node [[email protected] ~]# yum install chrony -y               installation Service [[email protected] ~]# sed -i  ' s/ #allow  192.168\/16/allow 192.168\/16/g '  /etc/chrony.conf [[email protected] ~]#  cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime     Change the time zone to start the NTP service [[Email  protected] ~]# systemctl enable chronyd.service[[email protected] ~]#  systemctl start chronyd.service Configuring compute nodes [[Email protected] ~]# yum install  chrony -y[[email protected] ~]# sed -i  ' s/^server.*$//g '  /etc/ chrony.conf [[email protected] ~]# sed -i  "n;2aserver controller  Iburst " /etc/chrony.conf [[email protected] ~]# cp /usr/share/zoneinfo/asia/ Shanghai /etc/localtime    changing the time zone to start the NTP service [[Email protected] ~]# systemctl enable chronyd.service[[email  protected] ~]# systemctl start chronyd.servic

5.openstack installation Package

All nodes Execute # yum install centos-release-openstack-newton-y# yum upgrade-y# yum install python-openstackclient Openstack-seli Nux-y

Basic preparation is basically done
