云计算之openstack-newton版搭建（一）

openstack搭建准备工作

• 主机名与服务器ip地址
  
  

[size=1em]

[size=1em]1 [size=1em]2

[size=1em][size=1em]controller 192.168.23.98（控制节点） [size=1em]compute1   192.168.23.61（计算节点）

2.配置hosts解析

[size=1em]

[size=1em]1 [size=1em]2 [size=1em]3 [size=1em]4 [size=1em]5 [size=1em]6

[size=1em][size=1em][root@controller ~]# vim /etc/hosts [size=1em]添加 [size=1em]192.168.23.98 controller [size=1em]192.168.23.61 compute1 [size=1em][root@controller ~]# scp /etc/hosts root@compute1:/etc/hosts            要保证每个节点的 [size=1em]hosts文件统一

3.验证

[size=1em]

[size=1em]1 [size=1em]2 [size=1em]3 [size=1em]4 [size=1em]5 [size=1em]6 [size=1em]7 [size=1em]8 [size=1em]9 [size=1em]10

[size=1em][size=1em][root@controller ~]# ping -c 4 compute1 [size=1em]PING compute1 (192.168.23.61) 56(84) bytes of data. [size=1em]64 bytes from compute1 (192.168.23.61): icmp_seq=1 ttl=64 time=0.639 ms [size=1em]64 bytes from compute1 (192.168.23.61): icmp_seq=2 ttl=64 time=0.307 ms [size=1em]64 bytes from compute1 (192.168.23.61): icmp_seq=3 ttl=64 time=0.324 ms [size=1em]64 bytes from compute1 (192.168.23.61): icmp_seq=4 ttl=64 time=0.312 ms [size=1em]--- compute1 ping statistics --- [size=1em]4 packets transmitted, 4 received, 0% packet loss, time 3000ms [size=1em]rtt min/avg/max/mdev = 0.307/0.395/0.639/0.142 ms

5.关闭selinx和防火墙firewalld

[size=1em]

[size=1em]1 [size=1em]2 [size=1em]3 [size=1em]4 [size=1em]5 [size=1em]6 [size=1em]7 [size=1em]8

[size=1em][size=1em]以下命令所有节点都执行 [size=1em]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config [size=1em]# setenforce 0 [size=1em]# systemctl stop firewalld.service [size=1em]# systemctl disable firewalld.service [size=1em]# reboot [size=1em]# sestatus –v         检查是否关闭成功 [size=1em]SELinux status:                 disabled

4.配置时间同步服务器（NTP）

[size=1em]

[size=1em]1 [size=1em]2 [size=1em]3 [size=1em]4 [size=1em]5 [size=1em]6 [size=1em]7 [size=1em]8 [size=1em]9 [size=1em]10 [size=1em]11 [size=1em]12 [size=1em]13 [size=1em]14 [size=1em]15

[size=1em][size=1em]控制节点 [size=1em][root@controller ~]# yum install chrony -y             安装服务 [size=1em][root@controller ~]# sed -i 's/#allow 192.168\/16/allow 192.168\/16/g' /etc/chrony.conf [size=1em][root@controller ~]# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime    更改时区 [size=1em]启动NTP服务 [size=1em][root@controller ~]# systemctl enable chronyd.service [size=1em][root@controller ~]# systemctl start chronyd.service [size=1em]配置计算节点 [size=1em][root@compute1 ~]# yum install chrony -y [size=1em][root@compute1 ~]# sed -i 's/^server.*$//g' /etc/chrony.conf [size=1em][root@compute1 ~]# sed -i "N;2aserver controller iburst" /etc/chrony.conf [size=1em][root@compute1 ~]# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime   更改时区 [size=1em]启动NTP服务 [size=1em][root@compute1 ~]# systemctl enable chronyd.service [size=1em][root@compute1 ~]# systemctl start chronyd.servic

5.openstack安装包

[size=1em]

[size=1em]1 [size=1em]2 [size=1em]3 [size=1em]4

[size=1em][size=1em]所有节点执行 [size=1em]# yum install centos-release-openstack-newton -y [size=1em]# yum upgrade -y [size=1em]# yum install python-openstackclient openstack-selinux -y

基本的准备基本完成
