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 (责任编辑：IT) |
