centos7配置静态ip
- ifconfig查看网卡信息并获取到网卡的名称eth0s3
ifconfig
- 进入到网卡配置目录
cd /etc/sysconfig/network-scripts/
- 找到步骤1中的eth0s3的配置文件,编辑
vim ifcfg-eth0s3
- 重启网卡
systemctl restart network.service
- ifconfig再次查看网卡信息并获取到网卡的名称eth0s3
- ping其他主机或者pingwww.baidu.com等都能ping通了
- 编辑etc/hosts,ip地址映射
vim /etc/hosts
- 修改主机名,修改完需要重启
vim /etc/hostname
网络时间协议(NTP
[控制节点安装NTP]
# yum install chrony (安装软件包)
# vi /etc/chrony.conf
server NTP_SERVER iburst 将原本servcer注释掉,增加这行
# systemctl enable chronyd.service (设置为系统自启动)
# systemctl enable chronyd.service (启动NTP)
[计算节点安装NTP]
# yum install chrony (安装软件包)
# vi /etc/chrony.conf
server controller iburst 将原本servcer注释掉,增加这行
# systemctl enable chronyd.service (设置为系统自启动)
# systemctl enable chronyd.service (启动NTP)
[验证NTP]
在控制节点和计算节点分别执行chronyc sources,出现截图如下
更换软件源

# yum repolist ##检查是否已添加至源列表
# yum clean all
# yum makecache
# yum repolist enabled 查看系统可用的源
[openstack包]
