iaas私有云搭建

配置网络，主机名

修改和添加/etc/sysconfig/network-scripts/ifcfg-enp*（具体的网口）文件。

controller节点：

[root@localhost ~]#
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-enoxxxxxx（网卡1）
BOOTPROTO=static  //修改IP为静态
ONBOOT=yes  //开机自启
IPADDR=192.168.1.10  	//添加IP地址
PREFIX=24					//添加子网掩码
GATEWAY=192.168.1.1    	//添加网关
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-enoxxxxxx（网卡2）
BOOTPROTO=static  //修改IP自动获取（dhcp）为静态
ONBOOT=yes  //开机不自启改为自启
IPADDR=192.168.2.10  	//添加IP地址
PREFIX=24					//添加子网掩码
[root@localhos t~]# hostnamectl set-hostname controller //名字命名
[root@localhos t~]# reboot						//重启
[root@controller ~]#

compute节点：

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-enoxxxxxx（网卡1）
BOOTPROTO=static  //修改IP为静态
ONBOOT=yes  //开机自启
IPADDR=192.168.1.20  	//添加IP地址
PREFIX=24					//添加子网掩码
GATEWAY=192.168.1.1    	//添加网关
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-enoxxxxxx（网卡2）
BOOTPROTO=static  //修改IP为静态
ONBOOT=yes  //开机自启
IPADDR=192.168.2.20  	//添加IP地址
PREFIX=24					//添加子网掩码
[root@localhos t~]# hostnamectl set-hostname compute //名字命名
[root@localhos t~]#  reboot                    //重新登陆
[root@compute ~]#

永久关闭防火墙和selinux

controller节点：

[root@controller ~]# systemctl stop firewalld
[root@controller ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

[root@controller ~]# setenforce 0
[root@controller ~]# 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
# 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

搭建ftp服务，并开启自启

[root@controller ~]# yum install  –y vsftpd
[root@controller ~]# vi /etc/vsftpd/vsftpd.conf
添加anon_root=/opt/
保存退出

[root@controller ~]# systemctl restart vsftpd
[root@controller ~]# systemctl enable vsftpd

配置NTP服务

安装ntp服务(时间同步)
（1）配置controller节点
[root@controller ~]# yum -y install ntp
[root@controller ~]# vim /etc/ntp.conf
添加以下内容（删除默认sever规则）
server 127.127.1.0
fudge 127.127.1.0   stratum 10

[root@controller ~]# systemctl restart ntpd
[root@controller ~]# systemctl enable ntpd
Created symlink from /etc/systemd/system/multi-user.target.wants/ntpd.service to /usr/lib/systemd/system/ntpd.service.

（2）配置compute节点
[root@compute ~]# yum install -y ntp
[root@compute ~]# ntpdate controller			//配置时间同步
 1 Oct 08:36:16 ntpdate[2255]: adjust time server 192.168.1.10 offset -0.229334 sec
[root@compute ~]# systemctl enable ntpd
Created symlink from /etc/systemd/system/multi-user.target.wants/ntpd.service to /usr/lib/systemd/system/ntpd.service.
