Importing alicloud ECS locally to solve deployment problems

Video Explanation ： Alibaba cloud ECS Import local , Resolve deployment issues

explain

 demand ： To be deployed on Alibaba cloud ECS Copy the image file to the local VM, And officially run 

 analysis ：1、 Alicloud downloads to the local raw.tar.gz Format , First decompress to raw
	 2、 And then in the application QEMU Tools will raw It can be interpreted as vmdk form 
	 3、 take vmdk Import VM

QEMU Installation and conversion

QEMU for Windows – Installers (64 bit) (weilnetz.de)

All the way next that will do , Press after installation , First configuration qemu Environment

cmd, Use qemu-img.exe --help Check if the configuration is successful , The following is the configuration success page

application ：qemu-img convert *.raw -f raw -O vmdk *.vmdk

vmdk Import VM

dracut Problem solving

Premise background ：

 There are many reasons for this problem , This problem occurs with virtual machines imported from alicloud , It's usually ： initramfs Files are created by old platform hardware , Hardware that does not support the new platform 

 terms of settlement ： Generate a new initramfs file 

 step ：1、 Boot from the rescue kernel 
	 2、 Get into boot Under the table of contents , to update initramfs file 

Start the system

The initial interface shows that there are three cores , After testing ,

• The first one is ： Beyond repair （ The kernel will be deleted later ）
• The second kind ： The kernel we will enter and operate normally
• The third kind of ： Rescue kernel , After entering, you can repair

Press... Quickly when entering ↓, Enter the rescue kernel

Input ： account number 、 password

Get into /boot Catalog , And then execute dracut -f Order reconstruction , Then restart the system boot

cd /boot
dracut -f initramfs-3.10.0-862.e.12.x86_64.img
reboot

Remove redundant kernels

View all the kernels in the system RPM package

rpm -qa | grep kernel

Check the current kernel version of the system

uname -a

yum remove kernel-headers-3.10.0-862.14.4.el7.x86_64
yum remove kernel-tools-libs-3.10.0-862.14.4.el7.x86_64
yum remove kernel-3.10.0-862.14.4.el7.x86_64
yum remove kernel-tools-3.10.0-862.14.4.el7.x86_64
yum remove kernel-devel-3.10.0-862.14.4.el7.x86_64

y/N？ y Just make sure

Be sure to delete it ！！

modify ip Address

Instructions vim /etc/sysconfig/network-scripts/ifcfg-eth0

BOOTPROTO="static" // Put it ip Set to not change 

#IP Address 
IPADDR=192.168.11.104  
# gateway   
GATEWAY=192.168.11.2   
# Domain name resolver 
DNS1=192.168.11.2

Restart network service systemctl restart network, Then you can see ip The address becomes what we set ：192.168.11.104

Set mapping cd /ect, then vim hosts

ending

Now it can operate normally ~
