1、配置本地源

mkdir /etc/yum.repos.d/bak_repo_bak
mv  /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak_repo_bak

cat <<END >/etc/yum.repos.d/repo.repo
[repo]
name=repo
baseurl=http://172.16.8.7/CentOS7.3-Mini-Ha-Pike/
gpgcheck=0 
enabled=1
proxy=_none_
END


cat <<END > /etc/yum.repos.d/CentOS-Base.repo
[base]
name=CentOS-7 - Base
baseurl=http://172.16.8.200/repos/centos/7/os/x86_64/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[updates]
name=CentOS-7 - Updates
baseurl=http://172.16.8.200/repos/centos/7/updates/x86_64/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[extras]
name=CentOS-7 - Extras
baseurl=http://172.16.8.200/repos/centos/7/extras/x86_64/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
END

注意：172.16.8.200为局域网本地源服务器

更新系统

yum update –y

删除文件

rm -rf /etc/yum.repos.d/CentOS-*

2、关闭防火墙和selinux

service firewalld  stop
chkconfig firewalld off 
sed -i  "s/^SELINUX=enforcing/SELINUX=disabled/g"  /etc/selinux/config
sed -i -e 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux
setenforce 0

3、修改主机名

hostnamectl set-hostname node1
hostnamectl set-hostname node2
hostnamectl set-hostname node3
hostnamectl set-hostname computer1
hostnamectl set-hostname computer2
hostnamectl set-hostname computer3

修改hosts文件

# cat <<"EOF">/etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.8.60 node1 
172.16.8.61 node2
172.16.8.62 node3
172.16.8.63 computer1
172.16.8.64 computer2
172.16.8.65 computer3
EOF

配置本地源

4、时间同步NTP

采用局域网NTP

# echo '* * * * * /usr/sbin/ntpdate NTP服务器地址 ' >/var/spool/cron/root

如果控制节点可以上网：

# echo '* * * * * /usr/sbin/ntpdate 202.108.6.95' >/var/spool/cron/root

5、安装一些工具

# yum install -y vim net-tools 
# yum install openstack-selinux –y

# yum install openstack-selinux python-openstackclient yum-plugin-priorities -y 

# yum install -y openstack-utils

6、重启机器

reboot

以为update过程升级了内核，需要重启下使内核生效

附录：

ntp服务器配置

# yum -y install ntp

修改配置文件/etc/ntp.conf

server 0.centos.pool.ntp.org iburst
server 1.centos.pool.ntp.org iburst
server 2.centos.pool.ntp.org iburst
server 3.centos.pool.ntp.org iburst
server 127.127.1.0
fudge 127.127.1.0 stratum 0

启动服务并设置开机启动

# systemctl start ntpd
# systemctl enable ntpd

查看ntp状态

# ntpq -p
