1 准备模板机
具体步骤如下:
1. 下载镜像安装系统
https://mirrors.aliyun.com/centos/7.5.1804/isos/x86_64/
2. 安装完成配置好IP ,关闭SELINUX ,关闭firewalld ,修改网卡名
3. 预设置好修改其他机器IP脚本
1.1 安装系统
略
1.2 模板机的设置
修改网卡名eth0
# 当前系统版本 [root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) # 修改网卡配置文件为eth0 [root@localhost ~]# cd /etc/sysconfig/network-scripts [root@localhost network-scripts]# mv ifcfg-enxxxx eth0 # 修改为静态ip [root@localhost network-scripts]# cat ifcfg-eth0 TYPE="Ethernet" BOOTPROTO="static" 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="eth0" DEVICE="eth0" ONBOOT="yes" IPADDR=10.0.0.79 NETMASK=255.255.255.0 GATEWAY=10.0.0.2 DNS1=10.0.0.2 # 禁用该可预测命名规则 # 在 grup 文件里面的 GRUB_CMDLINE_LINUX 变量添加 net.ifnames=0 biosdevname=0 [root@localhost ~]# cat /etc/default/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap net.ifnames=0 biosdevname=0 rhgb quiet" GRUB_DISABLE_RECOVERY="true" #运行命令重新生成GRUB配置并更新内核参数 [root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfg Generating grub configuration file ... Found linux image: /boot/vmlinuz-3.10.0-327.el7.x86_64 Found initrd image: /boot/initramfs-3.10.0-327.el7.x86_64.img Found linux image: /boot/vmlinuz-0-rescue-692c580a413f41d8b51ddc4724500560 Found initrd image: /boot/initramfs-0-rescue-692c580a413f41d8b51ddc4724500560.img done
关闭selinux
[root@localhost ~]# sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/sysconfig/selinux [root@localhost ~]# egrep -v "^#|^$" /etc/sysconfig/selinux SELINUX=disabled SELINUXTYPE=targeted
关闭firewalld
[root@localhost ~]# systemctl disable firewalld.service
重启系统
[root@localhost ~]# reboot
然后给批量创建虚拟机设置自定义的IP和主机名的脚本
[root@localhost ~]# cat /root/first.sh #!/bin/bash #Author:keme #Blog:https://www.cnblogs.com/keme #Time:2018-11-23 #Name:first.sh #Version:V1.0 #Description:This is a test script. ip=$1 hostname=$2 if [ $# -ne 2 ] then echo "sh $0 ip hostname" fi set_ip(){ sed -ri "/IPADDR/s#(.*.)\..*#\1.${ip}#" /etc/sysconfig/network-scripts/ifcfg-eth0 sed -ri "/IPADDR/s#(.*.)\..*#\1.${ip}#" /etc/sysconfig/network-scripts/ifcfg-eth1 echo "==============================================" echo "now you can running : service network restart" service network restart } set_hostname(){ sed -i "s#.*#${hostname}#" /etc/hostname hostnamectl set-hostname ${hostname} echo "==============================================" echo "hostname is : $(cat /etc/hostname)" echo "==============================================" } main(){ set_ip set_hostname } main [root@localhost ~]# chmod +x /root/first.sh
关机创建快照
2 目录规划
- 模板虚拟机所在目录
2.1 模板机所在目录
E:\VMS\Centos7\template
3 vmrun结合脚本批量创建虚拟机
- vmrun.exe 程序
- git 软件
- 编写脚本
- 设置IP 的脚本
3.1 vmrun.exe
找到vmrun.exe 程序
创建一个E:\SOFT\VM文件夹复制到新创建的文件夹
vmrun使用
https://www.cnblogs.com/qiaoyanlin/p/6883487.html
https://www.vmware.com/pdf/vix162_vmrun_command.pdf
3.2 git 软件作用
方便使用linux 的shell 命令
3.3 编写脚本
auto_VM.sh
内容如下
#!/bin/bash #Author:keme #Blog:https://www.cnblogs.com/keme/ #Time:2018-11-23 #Name:auto_vm.sh #Version:V1.0 PATH_TEM="/E/VMS/Centos7/template/template.vmx" PATH_SERVICE="/E/VMS/Centos7" PATH_SERVICE_CMD="E:\VMS\Centos7" ####################################### #PATH_TEM="/E/VMS/Debian8/template/template.vmx" #PATH_SERVICE="/E/VMS/Debian8" #PATH_SERVICE_CMD="E:\\VMS\\Debian8" ###################################### PATH_VMRUN_CMD="E:\\SOFT\\VM" PATH_VMS="E:\\VMS" SERVER_NAME="FDSF" CLUSTER_NAME="FDFS-cluster" SHOT_NAME="$2" # 创建克隆链接的虚拟机 VM_create(){ for i in $(cat host-list.txt) do echo "开始创建链接克隆: ${SERVER_NAME}-${i}" /E/SOFT/VM/vmrun.exe -T ws clone "${PATH_TEM}" ${PATH_SERVICE}/${CLUSTER_NAME}/${SERVER_NAME}-${i}/${SERVER_NAME}-${i}.vmx linked -snapshot=CLEAN -cloneName=${SERVER_NAME}-${i} sleep 2 done } # 启动创建好的虚拟机 VM_start(){ for i in $(cat host-list.txt) do echo "开始启动: ${SERVER_NAME}-${i}" /E/SOFT/VM/vmrun.exe -T ws start ${PATH_SERVICE}/${CLUSTER_NAME}/${SERVER_NAME}-${i}/${SERVER_NAME}-${i}.vmx sleep 10 done } # 批量修改IP地址 VM_set_IP(){ > ${PATH_VMS}\\set_ip.bat for i in $(cat host-list.txt) do echo "${PATH_VMRUN_CMD}\\vmrun.exe -T ws -gu root -gp 123456 runProgramInGuest \"${PATH_SERVICE_CMD}\\${CLUSTER_NAME}\\${SERVER_NAME}-${i}\\${SERVER_NAME}-${i}.vmx\" /bin/bash /root/first.sh ${i} ${SERVER_NAME}-${i}" >> ${PATH_VMS}\\set_ip.bat echo "ping -n 5 127.0.0.1 >nul" >> ${PATH_VMS}\\set_ip.bat done echo "修改IP脚本生成路径: ${PATH_VMS}\\set_ip.bat" echo -e "运行命令:\n1.打开cmd.exe\n2.输入: ${PATH_VMS}\\set_ip.bat" } # 修改好后批量关机 VM_stop(){ for i in $(cat host-list.txt) do echo "开始关闭: ${SERVER_NAME}-${i}" /E/SOFT/VM/vmrun.exe -T ws stop ${PATH_SERVICE}/${CLUSTER_NAME}/${SERVER_NAME}-${i}/${SERVER_NAME}-${i}.vmx sleep 2 done } # 关机后批量创建快照 VM_snapshot(){ for i in $(cat host-list.txt) do echo "开始快照: ${SERVER_NAME}-${i}" /E/SOFT/VM/vmrun.exe -T ws snapshot "${PATH_SERVICE}/${CLUSTER_NAME}/${SERVER_NAME}-${i}/${SERVER_NAME}-${i}.vmx" ${SHOT_NAME} sleep 2 done } # 获取快照列表 VM_shot_list(){ for i in $(cat host-list.txt) do echo "获取快照列表: ${SERVER_NAME}-${i}" /E/SOFT/VM/vmrun.exe -T ws listSnapshots "${PATH_SERVICE}/${CLUSTER_NAME}/${SERVER_NAME}-${i}/${SERVER_NAME}-${i}.vmx" sleep 2 done } # 批量恢复快照 VM_shot_back(){ for i in $(cat host-list.txt) do echo "开始恢复快照: ${SERVER_NAME}-${i} ${SHOT_NAME}" /E/SOFT/VM/vmrun.exe -T ws revertToSnapshot "${PATH_SERVICE}/${CLUSTER_NAME}/${SERVER_NAME}-${i}/${SERVER_NAME}-${i}.vmx" ${SHOT_NAME} sleep 2 done } # 批量删除快照 VM_shot_del(){ for i in $(cat host-list.txt) do echo "开始删除快照: ${SERVER_NAME}-${i} ${SHOT_NAME}" /E/SOFT/VM/vmrun.exe -T ws deleteSnapshot "${PATH_SERVICE}/${CLUSTER_NAME}/${SERVER_NAME}-${i}/${SERVER_NAME}-${i}.vmx" ${SHOT_NAME} sleep 2 done } # 获取当前正在运行的虚拟机 VM_list(){ echo "当前正在运行的虚拟机:" /E/SOFT/VM/vmrun.exe -T ws list } case $1 in create) VM_create ;; start) VM_start ;; stop) VM_stop ;; shot) VM_snapshot ;; set_ip) VM_set_IP ;; shot_back) VM_shot_back ;; shot_del) VM_shot_del ;; shot_list) VM_shot_list ;; list) VM_list ;; *) echo "bash $0 {create|start|set_ip|stop|shot|shot_list|shot_back|shot_del|list}" esac
除了 set_ip
这个函数在windows 里面需要单独拿出来放到cmd 窗口使用
host-list.txt
表示创建虚拟机的数量,80,81,82表示最后的ip地址第四位
设置IP的脚本
E:\VMS\set_ip.bat
E:\SOFT\VM\vmrun.exe -T ws -gu root -gp 123456 runProgramInGuest "E:\VMS\Centos7\FDFS-cluster\FDSF-80\FDSF-80.vmx" /bin/bash /root/first.sh 80 FDSF-80 ping -n 5 127.0.0.1 >nul E:\SOFT\VM\vmrun.exe -T ws -gu root -gp 123456 runProgramInGuest "E:\VMS\Centos7\FDFS-cluster\FDSF-81\FDSF-81.vmx" /bin/bash /root/first.sh 81 FDSF-81 ping -n 5 127.0.0.1 >nul E:\SOFT\VM\vmrun.exe -T ws -gu root -gp 123456 runProgramInGuest "E:\VMS\Centos7\FDFS-cluster\FDSF-82\FDSF-82.vmx" /bin/bash /root/first.sh 82 FDSF-82 ping -n 5 127.0.0.1 >nul
4 模拟演示创建,修改ip和主机名
- 创建虚拟机
- 开启所创建的虚拟机
ok 都启动了
- 设置所创建虚拟机的ip 和 主机名
- 查看是否修改成功了
FAST-80 ,OK
FAST-81,OK
FAST-82,OK
注: 只是为了方便做实验用,方便自己快速搭建环境练习测试
