OpenStack-Queens——环境准备-网络配置

 

controller

为了方便后面的搭建，这里把虚拟机的名称改为controller

hostnamectl set-hostname controller

Ctrl+D 重新登录即可生效

修改网卡配置文件

第一张网卡作为管理网络，并不需要设置网关。

vi /etc/sysconfig/network-scripts/ifcfg-ens33

BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.100.10
PREFIX=24

第二张网卡作为外部网络，需要配置网关，并且设置DNS

vi /etc/sysconfig/network-scripts/ifcfg-ens34

BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.200.10
PREFIX=24
GATEWAY=192.168.200.2
DNS1=114.114.114.114
DNS2=8.8.8.8

重启网卡

systemctl restart network

写入hosts解析

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

 关闭防火墙firewalld

systemctl stop firewalld.service
systemctl disable firewalld.service

关闭selinux

vi /etc/selinux/config

SELINUX=disabled

要使设置生效你可以选择重启或者：

setenforce 0

compute

修改虚拟机名称

hostnamectl set-hostname compute

修改网卡配置

vi /etc/sysconfig/network-scripts/ifcfg-ens33

BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.100.20
PREFIX=24

vi /etc/sysconfig/network-scripts/ifcfg-ens34

BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.200.20
PREFIX=24
GATEWAY=192.168.200.2
DNS1=114.114.114.114
DNS2=8.8.8.8

写入hosts解析

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

关闭防火墙firewalld

systemctl stop firewalld.service
systemctl disable firewalld.service

关闭selinux

vi /etc/selinux/config

SELINUX=disabled

要使设置生效你可以选择重启或者：

setenforce 0

验证操作 

网络时间协议(NTP)

controller

安装软件包

yum install chrony

编辑/etc/chrony.conf文件，配置时钟源同步服务端

vi /etc/chrony.conf

server time.windows.com iburst
allow 192.168.100.0/24

设置NTP服务开机启动

systemctl enable chronyd.service
systemctl start chronyd.service

compute

安装软件包

yum install chrony

编辑/etc/chrony.conf文件，配置时钟源同步服务端

vi /etc/chrony.conf

server controller iburst

设置NTP服务开机启动

systemctl enable chronyd.service
systemctl start chronyd.service
