一、Openstack_Ocata环境部署准备

OpenStack Ocata环境搭建准备

环境准备

1、workstation下配置3个虚拟交换机

点击编辑——>虚拟网络编辑器

虚拟网络编辑器

名称 IP地址 作用
VMnet1 10.1.1.0 Openstack内部管理网络
VMnet2 10.2.2.0 Openstack隧道网络,用于vxlan
VMnet6 9.110.187.0 相当于公网
注意:VMnet6的网关地址为9.110.187.2,关闭每个网段的DHCP功能

2、安装虚拟机环境

4、进入操作系统后,进行系统初始化

a、关闭系统防火墙和selinux

[root@localhost ~]# systemctl disable firewalld.service
[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# systemctl status firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
Jun 03 07:02:40 localhost.localdomain systemd[1]: Starting firewalld - dynamic firewall daemon...
Jun 03 07:02:43 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon.
Jun 03 07:05:39 localhost.localdomain systemd[1]: Stopping firewalld - dynamic firewall daemon...
Jun 03 07:05:40 localhost.localdomain systemd[1]: Stopped firewalld - dynamic firewall daemon.
Jun 03 07:11:27 localhost.localdomain systemd[1]: Stopped firewalld - dynamic firewall daemon.

[root@localhost ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config 
[root@localhost ~]# cat /etc/selinux/config 
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted 

[root@localhost ~]# setenforce 0

b、配置三个网卡的网络如下:

[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno16777736 
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes

NETMASK=255.255.255.0
DNS1=114.114.114.114
DNS2=8.8.8.8

[root@localhost ~]# systemctl restart network
[root@localhost ~]# ip a

[root@localhost ~]# ping www.baidu.com

c、修改主机名并且重启系统

[root@localhost ~]# hostnamectl set-hostname controller1

d、安装一些初始化工具

[root@controller1 ~]# yum install lrzsz ntpdate unzip wget net-tools vim -y
注意:不需要执行 yum update -y 操作,可能会导致部分软件的冲突
