Ke hana nei i kāu kiʻi ponoʻī me CentOS 5.9 maʻemaʻe ma ke ao Amazon

E like me kāu e ʻike ai, ma ka Amazon cloud virtual i hoʻokumu ʻia ma muli o nā kiʻi (ka mea i kapa ʻia AMI). Hāʻawi ʻo Amazon i kahi helu nui o lākou; hiki iā ʻoe ke hoʻohana i nā kiʻi ākea i hoʻomākaukau ʻia e nā ʻaoʻao ʻekolu, no ka mea, ʻaʻohe kuleana o ka mea hāʻawi kapua. Akā i kekahi manawa pono ʻoe i kahi kiʻi ʻōnaehana maʻemaʻe me nā palena kūpono, ʻaʻole i loko o ka papa inoa o nā kiʻi. A laila ʻo ke ala wale nō e hana ai i kāu AMI ponoʻī.

Hōʻike ka palapala kūhelu ala ka hana ʻana i kahi "AMI i kākoʻo ʻia e ka hale kūʻai". ʻO ka hemahema o kēia ala, ʻo ke kiʻi i hoʻopau ʻia e pono e hoʻololi ʻia i "AMI kākoʻo EBS"

Pehea e hana ai i kāu AMI ponoʻī i kākoʻo ʻia e EBS ma ke ao Amazon me ka ʻole o nā pae waena e kūkākūkā ʻia ma kēia ʻatikala.

Hōʻuluʻulu Hana:

  • E hoʻomākaukau i ke kaiapuni
  • E hoʻouka i kahi pūnaewele maʻemaʻe a hana i nā hoʻonohonoho pono
  • E kiʻi i kahi kiʻi o ka disk
  • Kakau AMI

Hoʻomākaukau i ke Kaiapuni

No kā mākou kumu, kūpono kēlā me kēia ʻano o ke ʻano, ʻo t1.micro. Hiki iā ʻoe ke holo ma o ka CLI:

aws ec2 run-instances --image-id ami-1624987f --max-count 1 --min-count 1 --key-name mel --instance-type t1.micro

E hana kāua ebs-volume, kahi e hoʻokomo ai i kā mākou ʻōnaehana ma hope:

aws ec2 create-volume --availability-zone us-east-1a --size 10

E hana kēia kauoha i kahi diski 10 Gb no mākou. Mea nui: pono ka disk ma ka ʻāpana like me ka laʻana (i kā mākou hihia ʻo us-east-1a).
A laila, pono ʻoe e hoʻopili i ka disk i ka laʻana:

aws ec2 attach-volume --instance-id i-2bc0925b --volume-id vol-08ab3079 --device /dev/xvdf

I kēia manawa, e hoʻokomo i ka laʻana ma o ssh, e hōʻano i ka disk a kau i loko o ka papa kuhikuhi:

mkfs.ext3 /dev/xvdf
mkdir /mnt/centos-image
mount /dev/xvdf /mnt/centos-image
cd !$

Ke hoʻokomo nei i ka Centos maʻemaʻe 5.9

Ma mua o ka hoʻokomo ʻana i ka ʻōnaehana, pono ʻoe e hana i kahi lāʻau papa kuhikuhi, mount proc a me sysfs, a hana i kahi liʻiliʻi o nā mea hana:

mkdir centos-image/{boot,tmp,dev,sys,proc,etc,var}
mount -t proc none /mnt/centos-image/proc/
mount -t sysfs none /mnt/centos-image/sys/
for i in console null zero ; do /sbin/MAKEDEV -d /mnt/centos-image/dev -x $i ; done

E hoʻokomo mākou i ka ʻōnaehana me ka hoʻohana ʻana i ka yum a me kēia faila hoʻonohonoho:

yum -c ~/yum-centos.conf --installroot=/mnt/centos-image/ -y groupinstall Base

Ma hope o ka hoʻopau ʻana i ke kaʻina hana, hiki iā ʻoe ke hoʻokomo i nā pūʻolo pono ma ke ʻano like:

yum -c ~/yum-centos.conf --installroot=/mnt/centos-image/ install $packet_name

E hoʻoponopono iā fstab:

vi /mnt/centos-image

/dev/xvda1  /      ext3    defaults        0 0
none       /dev/pts  devpts  gid=5,mode=620  0 0

none       /proc     proc    defaults        0 0
none       /sys      sysfs   defaults        0 0

Ma CentOS 5.9 pono ʻoe e hoʻokomo i kahi kernel me ke kākoʻo xen:

yum -c ~/yum-centos.conf --installroot=/mnt/centos-image/ -y install kernel-xen

E hoʻouka iā Grub:

chroot /mnt/centos-image/ grub-install /dev/xvdf

a hana i kahi initrd hou:

chroot /mnt/centos-image/
cd boot/
mkinitrd --omit-scsi-modules --with=xennet --with=xenblk --fstab=/etc/fstab --preload=xenblk initrd-2.6.18-348.1.1.el5xen.img 2.6.18-348.1.1.el5xen

He mea koʻikoʻi ke kuhikuhi ʻana i kēia mau ʻāpana āpau a me kahi fstab hou, inā ʻaʻole e holo ka ʻōnaehana.
A laila pono ʻoe e hana i kahi faila menu.lst no grub:

default=0
timeout=5
hiddenmenu

        root (hd0)
        kernel /boot/vmlinuz-2.6.18-348.1.1.el5xen ro root=/dev/xvda1
        initrd /boot/initrd-2.6.18-348.1.1.el5xen.img

E hoʻonohonoho i ka pūnaewele a me sshd:

No laila, e loaʻa iā mākou kahi pūnaewele hana a me ka hiki ke komo i loko o ka hihia me ka hoʻohana ʻana i nā kī. Akā ʻo ke kī ponoʻī pono e hoʻoneʻe ʻia i ke ʻano. Hiki ke hana i kēia me ka hoʻohana ʻana i kahi ʻatikala e lawe i ke kī a mālama iā ia ma ke ʻano:

Pono nō hoʻi e hoʻopau iā Selinux, a i ʻole e hoʻonohonoho pono iā ia. A i ʻole, no ka laʻana, ʻaʻole hiki ke mālama ʻia ke kī ma ka laʻana.
I kēia manawa hiki iā ʻoe ke hoʻōki i ka hoʻonohonoho ʻana i ka ʻōnaehana. Loaʻa iā mākou ka CentOS maʻemaʻe e holo i ke ao. ʻO ka mea i koe, ʻo ka wehe ʻana i ka disk ebs me kā mākou ʻōnaehana a hoʻopaʻa inoa ami.

umount /mnt/centos-image/proc/
umount /mnt/centos-image/sys/
umount /mnt/centos-image/

kakau inoa AMI

No ka loaʻa ʻana o ka ami mai kahi ebs disk, pono ʻoe e lawe i kahi kiʻi o ka disk:

aws ec2 create-snapshot --volume-id vol-0b4bd07a --description centos-snap

ʻO ke ala maʻalahi loa e hoʻopaʻa inoa ami ma o ka AWS Management Console. No ka hana ʻana i kēia, pono ʻoe e hele i ka ʻāpana "Snapshots" i ka lawelawe EC2, koho i ka mea āu e pono ai (i kā mākou hihia he centos-snap), kaomi pololei ma luna a koho i ka "Hana i ke kiʻi mai Snapshot"
A laila, i ka puka aniani e wehe ai, pono ʻoe e koho i nā ʻāpana aʻe:

Ke hana nei i kāu kiʻi ponoʻī me CentOS 5.9 maʻemaʻe ma ke ao Amazon

Hiki iā ʻoe ke ʻike i ka Kernel ID e koho ai penei:

aws ec2 describe-images --owner amazon --region us-east-1 --output text | grep "/pv-grub-hd0.*-x86_64" | awk '{print $7}' | grep aki
aki-88aa75e1
aki-b4aa75dd

ʻo ia wale nō. I kēia manawa hiki iā ʻoe ke hoʻomaka i nā hiʻohiʻona.
Ma kēia ala, hiki iā ʻoe ke hana i kahi kiʻi, ʻoi aku paha, me kekahi mahele Linux. Ma ka liʻiliʻi loa, ʻo Debian (e hoʻohana ana i ka debootstrap e hoʻokomo i kahi ʻōnaehana maʻemaʻe) a me Rhel-ʻohana.
