OpenStack云平台搭建需要两个节点,一个是controller(控制节点),另一个是compute(计算节点)。
控制节点(controller)规划如下:
一块200G的硬盘。两块网卡,第一块网卡IP地址使用192.168.100.10,第二块网卡IP地址使用192.168.200.10。
计算节点(compute)规划如下:
一块200G的硬盘和一块100G的硬盘。两块网卡,第一块网卡IP地址使用192.168.100.20,第二块网卡IP地址使用192.168.200.20。
云平台搭建需要使用centos7.5及7.0版本的镜像和chinaskills_cloud_iaas.iso镜像,镜像提供如下:
centos7.5镜像链接:https://pan.baidu.com/s/1stvdGLKTwVqrAyzTW-WQuA
提取码:yjsqcentos7.0镜像链接:https://pan.baidu.com/s/10zQAxkSqO37_EAX2wVyy9A
提取码:yjsqiaas镜像链接:https://pan.baidu.com/s/11iAL7pQf31Kyer2UfVe2ZA
提取码:yjsq
重启后使用root用户登录,然后修改主机名,配置网卡、内核。
修改、添加内容如下 (注:按下i键进入插入模式,按下ESC键,然后输入冒号wq退出)。
修改、添加内容如下:
重启网卡,使配置生效。
使用ip a 命令检验配置是否生效。
4.修改内核。
添加内容如下:
刷新内核,然后重启使配置生效。
重启之后使用SecureCRT连上controller节点。(注:连接SecureCRT是为了方便)
注意:VMnet8必须跟controller节点和compute节点在同一个网段才能连接上SecureCRT。
输入密码后,点击“确定”即可连接上SecureCRT。
出现以下图示表示连接成功。
说明:compute节点与controller节点基础环境及安装系统大致相同,可参考controller节点配置,以下是稍有不同的地方。
第一块网卡配置如下:
第二块网卡配置如下:
注意:compute节点也需要连上SecureCRT。
centos7.0镜像上传方式如上。
[root@controller ~]# systemctl stop firewalld #关闭防火墙
[root@controller ~]# systemctl disable firewalld #设置防火墙开机不自启
