Centos7单机部署openstack ——All In One

前期准备：

一.准备一台虚拟机

8核

100G磁盘

手动分区

/home 41.12GiB

/boot 512MiB

/ 50.5Gib

swap 4096MiB

centos-root 挂载点/

期望容量 70 GiB

接受更改后点击完成

开启以太网，必须开启ens33

暂时不修改主机名

禁用Kdump

设置root密码

二.ssh连接

1.完成后登录查看地址

ip a

2.关闭防火墙，禁用防火墙

systemctl stop firewalld
systemctl disable firewalld

3.测试连接

ping baidu.com

三.安装前设置

4.禁用防火墙

systemctl disable firewalld

5.禁用selinux

vi /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  #这里设置为disable
# 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

6.保存退出后重启虚拟机

reboot

7.启用network服务 ——一定要！！！

systemctl enable network
systemctl start network

8.修改主机名以及映射

hostnamectl set-hostname openstack

vi /etc/hosts
#在最后添加 ip  hostname  hostname.localdomain
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.35   openstack openstack.localdomain

保存退出后测试ping通主机名

[root@localhost ~]# ping openstack
PING openstack (192.168.200.354) 56(84) bytes of data.
64 bytes from openstack (192.168.200.35): icmp_seq=1 ttl=64 time=0.020 ms
64 bytes from openstack (192.168.200.35): icmp_seq=2 ttl=64 time=0.046 ms
^Z
[1]+  已停止               ping openstack

9.进行时间同步

[root@localhost ~]# yum install -y chrony
