startup GUI di slackware
slackware defaultnya running level3 yang boot masyk command propt mode
untukmengubah ke boot mode GUI lakukan langkah di bawah ini:
edit file di : /etc/inittab
temukan baaris berikut :
# Default run level. (Do not set to 0 or 6)
id:3:initdefault:
ubah angka 3 diatas menjadi angka 4 untuk mode GUI
=============================
install Grub buat slackware :
http://slackbuilds.org/repository/13.1/system/grub2/
download :ftp://alpha.gnu.org/gnu/grub/grub-1.98.tar.gz
http://slackbuilds.org/slackbuilds/13.1/system/grub2.tar.gz
tar -xvf grub2.tar.gz
mv grub-1.98.tar.gz grub2/
cd grub2
./grub2.SlackBuild
cd /tmp
installpkg grub2-1.98-x86_64-2_SBo.tgz
cat /proc/mdstat
grub-install /dev/md0
berikut ini pilihan bisa 2 cara :
1.grub-mkconfig -o /boot/grub/grub.cfg
hasilnya masih kosong...
2.copy grub.cfg
cp /usr/doc/grub2-1.98/grub.cfg /boot/grub2/
saya pilih yang no 2.
edit file grub.cfg jadi :
---------------------------------------------------------------
#
# Sample GRUB configuration file
#
# Boot automatically after 30 secs.
set timeout=10
# By default, boot the first entry.
set default=0
# Fallback to the second entry.
set fallback=1
# For booting GNU/Linux
menuentry "linuxslac_serever" {
set root='(md0)'
linux /boot/vmlinuz root=/dev/md0
initrd
}
# Change the colors.
menuentry "Change the colors" {
set menu_color_normal=light-green/brown
set menu_color_highlight=red/blue
}
==============================
lupa password :
boot dari media apa aja ( cd linux/flashdisk atau yg lain )
yg penting bisa akses HDD asli yang buat boot :
masuk command prompt :
create direktori :
mkdir /mnt/satu
mount HDD asli :
mount /dev/sda2 /mnt/satu
kemudian masuk ke folder /etc/passwd ( di hdd asli nya :
cd /mnt/satu/etc/
vi passwd
cari bagian :
root:x:0:0::/root:/bin/bash
bin:x:1:1:bin:/bin:/bin/false
daemon:x:2:2:daemon:/sbin:/bin/false
adm:x:3:4:adm:/var/log:/bin/false
lp:x:4:7:lp:/var/spool/lpd:/bin/false
sync:x:5:0:sync:/sbin:/bin/sync
shutdown:x:6:0:shutdown:/sbin:/sbin/shutdown
...
pada bagian :
root:x:0:0::/root:/bin/bash
hilangkan huruf x nya menjadi :
root::0:0::/root:/bin/bash
kemudian save : esc --> wq enter
kemudian reboot , dan boot dari flash Haddisk asli :
insyalloh password jadi kosong...
login pake root untuuk password jangan ketik apa1 tapi langsung enter.
setelah bisa masuk baru buat passwoed baru lagi...

=================================create swap file ====================================
8G memory swap
root@darkstar:/etc/rc.d# dd if=/dev/zero of=/swapfile bs=1024 count=8000000
8000000+0 records in
8000000+0 records out
8192000000 bytes (8.2 GB) copied, 74.8582 s, 109 MB/s
# dd if=/dev/zero of=/mnt/swap/swapfile bs=1k count=20480
# mkswap /mnt/swap/swapfile
# swapon /mnt/swap/swapfile
To make it enable at boot, you need to add the swap file in the /etc/fstab file like below:
/swap1 swap swap defaults 0 0
1. Adding swap file on Linux
Login as root or change to super user then type the following command to create 1 GB swap file.
dd if=/dev/zero of=/swap1 bs=1M count=1024
bash-3.1# dd if=/dev/zero of=/swap1 bs=1M count=1024
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 28.3646 s, 37.9 MB/s
Run ?mkswap? to set up a Linux swap area on a device or in a file, in this case in the /swap1 file.
mkswap /swap1
For example:
bash-3.1# mkswap /swap1
Setting up swapspace version 1, size = 1048572 KiB
no label, UUID=e501fc72-f731-4624-ab45-ee898f6cf1c5
After setting up the swap area, now we need to enable / activate the swap file by using ?swapon? command.
swapon /swap1
You are done. But the swap file will be disable if you reboot the system.
To make it enable at boot, you need to add the swap file in the /etc/fstab file like below:
/swap1 swap swap defaults 0 0
----------
dd if=/dev/zero of=/swap1 bs=1M count=1024
mkswap /swap1
swapon /swap1
