1、背景

近日将主要精力放在Linux下测试MySQL Replication,宿主机安装了Centos7.0系统,需要安装三台虚拟机。因此,尝试了一下在Centos7.0上安装虚机机。



2、安装步骤



(1)yum源安装软件(前提:CPU开启虚拟化)

[root@localhost ~]# yum install qemu-kvm libvirt virt-install bridge-utils virt-manager vir-viewer



(2)查看模块支持

[root@localhost ~]# lsmod | grep kvm #make sure modules are loaded

kvm_intel 138567 0

kvm 441119 1 kvm_intel



(3)启动服务

[root@localhost ~]# systemctl enable libvirtd

[root@localhost ~]# systemctl start libvirtd



(4)配置网络

[root@localhost ~]# cd /etc/sysconfig/network-scripts/

[root@localhost network-scripts]# cp ifcfg-enp3s0 ifcfg-br0

[root@localhost network-scripts]# cat ifcfg-br0

TYPE=Bridge

BOOTPROTO=none

DEVICE=br0

ONBOOT=yes

IPADDR0=192.168.9.233

PREFIX0=26

GATWAY0=192.168.9.254



[root@localhost network-scripts]# cat ifcfg-enp3s0

HWADDR=AC:22:0B:74:57:1E

TYPE=Ethernet

BRIDGE=br0

BOOTPROTO=none

DEFROUTE=yes

PEERDNS=yes

PEERROUTES=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

IPV6_FAILURE_FATAL=no

NAME="enp3s0"

UUID=1c80a08d-be65-462b-9788-84dd477f3360

ONBOOT=yes



[root@localhost network-scripts]# systemctl restart network
