回馈loc——pacificrack（pr）手动VNC安装centos7.2_美国VPS

感谢MJJ们总是第一时间发羊毛信息到论坛

只是用于1G内存的小鸡，512M的不用试了，内存太小。

pacificrack的centos6模板有问题，进入管理面板重装系统：Fedora 23 x86_64。

Fedora的安装命令好像是dnf，用习惯了yum，无视提示不管也能用。

yum install -y wget
cd /boot
wget http://vault.centos.org/7.2.1511/os/x86_64/images/pxeboot/vmlinuz -O vmlinuz-7
wget http://vault.centos.org/7.2.1511/os/x86_64/images/pxeboot/initrd.img -O /boot/initrd-7.img

复制代码

cat /boot/grub2/grub.cfg

复制代码

查看/boot/grub2/grub.cfg，找到如下代码部分（下面的38e2da31-8c88-494f-8497-e206c326634c换成你自己的）：

menuentry ‘Fedora (4.2.6-301.fc23.x86_64) 23 (Server Edition)’ –class fedora –class gnu-linux –class gnu –class os –unrestricted $menuentry_id_option ‘gnulinux-4.2.3-300.fc23.x86_64-advanced-38e2da31-8c88-494f-8497-e206c326634c’ {
load_video
set gfxpayload=keep
insmod gzio
insmod part_msdos
insmod ext2
set root=’hd0,msdos1′
if [ x$feature_platform_search_hint = xy ]; then
search –no-floppy –fs-uuid –set=root –hint=’hd0,msdos1′ 38e2da31-8c88-494f-8497-e206c326634c

initrd16 /boot/initramfs-4.2.6-301.fc23.x86_64.img
}

复制代码

然后把这一段拷贝到/etc/grub.d/40_custom中做如下修改（下面的38e2da31-8c88-494f-8497-e206c326634c换成你自己的）：

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the ‘exec tail’ line above.
menuentry ‘NetInstall’ {
load_video
set gfxpayload=keep
insmod gzio
insmod part_msdos
insmod ext2
set root=’hd0,msdos1′
if [ x$feature_platform_search_hint = xy ]; then
search –no-floppy –fs-uuid –set=root –hint=’hd0,msdos1′ 38e2da31-8c88-494f-8497-e206c326634c
else
search –no-floppy –fs-uuid –set=root 38e2da31-8c88-494f-8497-e206c326634c
fi

}

复制代码

# 重建grub配置

grub2-mkconfig -o /boot/grub2/grub.cfg

复制代码

# 列出所有启动条目

awk -F\’ ‘$1=="menuentry " {print $2}’ /etc/grub2.cfg

复制代码

# 下一次启动使用NetInstall，仅使用一次

grub2-reboot NetInstall

复制代码

# 重启系统

reboot

复制代码

使用VNC安装CentOS系统，你的小鸡ip，端口1

然后，没有了，开始安装。
