Instalasi Centos 7 secara remote via VNC pada prinsipnya sama dengan instalasi Centos 6, hanya saja karena Centos 7 menggunakan versi grub yang berbeda maka ada perbedaan ssetting sbb:<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Pastikan anda sudah mencatat\u00a0IP Address, Gateway, Netmask, dan nama interface (eth0, eth1, venet0, dsb) dengan benar.<\/p>\n

Langkah 1:\u00a0 Copy file bootstrap (Linux kernel image dan ramdisk image) ke partisi \/ boot Anda:<\/p>\n

cd \/boot\r\nwget http:\/\/mirror.centos.org\/centos\/7\/os\/x86_64\/isolinux\/vmlinuz -O vmlinuz-7\r\nwget http:\/\/mirror.centos.org\/centos\/7\/os\/x86_64\/isolinux\/initrd.img -O initrd-7.img<\/code><\/pre>\n

\nLangkah 2: Buat menu entry<\/p>\n
Paling aman anda copy isi dari file\u00a0\/boot\/grub2\/grub.cfg ke \/etc\/grub.d\/40_custom, misal isinya sbb:<\/p>\n
menuentry 'CentOS Linux, with Linux 3.10.0-123.el7.x86_64' --class centos --class gnu-linux --class gnu --class os --unrestricted $menuentry_id_option 'gnulinux-3.10.0-123.el7.x86_64-advanced-ac9e46e0-6de5-4e6f-baf2-cca39dffe49b' {\r\n    load_video\r\n    set gfxpayload=keep\r\n    insmod gzio\r\n    insmod part_msdos\r\n    insmod ext2\r\n    set root='hd0,msdos1'\r\n    if [ x$feature_platform_search_hint = xy ]; then\r\n      search --no-floppy --fs-uuid --set=root --hint='hd0,msdos1'  ac9e46e0-6de5-4e6f-baf2-cca39dffe49b\r\n    else\r\n      search --no-floppy --fs-uuid --set=root ac9e46e0-6de5-4e6f-baf2-cca39dffe49b\r\n    fi\r\n    linux16 \/vmlinuz-3.10.0-123.el7.x86_64 root=UUID=ac9e46e0-6de5-4e6f-baf2-cca39dffe49b ro vconsole.keymap=us crashkernel=auto  vconsole.font=latarcyrheb-sun16 rhgb quiet LANG=en_US.UTF-8\r\n    initrd16 \/initramfs-3.10.0-123.el7.x86_64.img\r\n}<\/code><\/pre>\n
Edit menu entry title, linux16, initrd16, misal menjadi seperti di bawah ini<\/p>\n
#!\/bin\/sh\r\nexec tail -n +3 $0\r\n# This file provides an easy way to add custom menu entries.  Simply type the\r\n# menu entries you want to add after this comment.  Be careful not to change\r\n# the 'exec tail' line above.\r\n\r\nmenuentry 'NetInstall' {\r\n    load_video\r\n    set gfxpayload=keep\r\n    insmod gzio\r\n    insmod part_msdos\r\n    insmod ext2\r\n    set root='hd0,msdos1'\r\n    if [ x$feature_platform_search_hint = xy ]; then\r\n      search --no-floppy --fs-uuid --set=root --hint='hd0,msdos1'  ac9e46e0-6de5-4e6f-baf2-cca39dffe49b\r\n    else\r\n      search --no-floppy --fs-uuid --set=root ac9e46e0-6de5-4e6f-baf2-cca39dffe49b\r\n    fi\r\n    linux16 \/vmlinuz-7 inst.vnc inst.vncpassword=12345678 inst.headless ip=ip::gateway:netmask::interface:none nameserver=8.8.8.8 inst.repo=http:\/\/mirror.centos.org\/centos\/7\/os\/x86_64\/ inst.lang=en_US inst.keymap=us\r\n    initrd16 \/initrd-7.img\r\n}<\/code><\/pre>\n
Note:<\/strong> Ganti ip=ip::gateway:netmask::interface:none sesuai parameter network server anda. sesuaikan bila menggunakan UEFI based.<\/p>\n
Langkah 3: Konfigurasi Grub<\/p>\n
Pastikan Grub menggunakan custom menu entry sekali. Edit\u00a0\/etc\/default\/grub<\/code>, ubah\u00a0GRUB_DEFAULT=0<\/code>\u00a0menjadi\u00a0GRUB_DEFAULT=saved<\/code><\/p>\n
Simpan konfigurasinya, rebuild grub<\/p>\n
grub2-mkconfig -o \/boot\/grub2\/grub.cfg<\/code><\/pre>\n
Cek list dari custom menu entry<\/p>\n
awk -F\\' '$1==\"menuentry \" {print $2}' \/etc\/grub2.cfg<\/code><\/pre>\n
pastikan isi menu entry sudah benar, terutama parameter network<\/p>\n
grub2-editenv list<\/code><\/pre>\n
Reboot menggunakan custom menu entry<\/p>\n
grub2-reboot NetInstall<\/code><\/pre>\n
Pastikan koneksi internet anda stabil, jika putus ditengah jalan maka anda harus kontak DC untuk meminta install ulang atau install dari client area bila disediakan oleh provider anda.<\/p>\n","protected":false},"excerpt":{"rendered":"
