一、Openstack_Ocata环境部署准备

OpenStack Ocata环境搭建准备

1、workstation下配置3个虚拟交换机

点击编辑——>虚拟网络编辑器

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

3、安装操作系统

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

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
