Openstack环境准备篇(上)

controller

外部网络：192.168.200.10

管理网络：192.168.100.10

compute

外部网路：192.168.200.20

管理网络：192.168.100.20

controller节点上

修改网卡配置文件

1.外部网络

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

BOOTPROTO=staticONBOOT=yesIPADDR=192.168.200.10NETMASK=255.255.255.0GATEWAY=192.168.200.1DNS1=114.114.114.114

2.管理网络

vi /etc/sysconfig/network-scripts/ifcfg-eno33554960

BOOTPROTO=staticONBOOT=yesIPADDR=192.168.100.10NETMASK=255.255.255.0GATEWAY=192.168.100.1DNS1=114.114.114.114

写入hosts解析

echo 192.168.100.10 controller >> /etc/hostsecho 192.168.100.20 compute >> /etc/hosts

重启网卡

systemctl restart network.service

如果你有网可以试试ping一下百度看能否联网

ping -c 4 www.baidu.comPING www.a.shifen.com (180.97.33.107) 56(84) bytes of data.64 bytes from 180.97.33.107: icmp_seq=1 ttl=128 time=37.2 ms64 bytes from 180.97.33.107: icmp_seq=2 ttl=128 time=37.5 ms64 bytes from 180.97.33.107: icmp_seq=3 ttl=128 time=37.4 ms64 bytes from 180.97.33.107: icmp_seq=4 ttl=128 time=37.3 ms--- www.a.shifen.com ping statistics ---4 packets transmitted, 4 received, 0% packet loss, time 3004msrtt min/avg/max/mdev = 37.222/37.397/37.548/0.266 ms

关闭防火墙firewalld

systemctl stop firewalld.servicesystemctl disable firewalld.service

关闭selinux

vi /etc/selinux/configSELINUX=disabled要使设置生效你可以选择重启或者：setenforce 0

测试

两边节点都需要

ping -c 4 controllerping -c 4 compute

如果正常进行下一步，本地源设置
