ความต้องการ
อยากให้ CentOS ทำงานในแบบ text-mode โดยยังคง Desktop package ไว้อยุ่

วิธีทำ
แก้ไฟล์ /etc/inittab

# System initialization is started by /etc/init/rcS.conf
#
# Individual runlevels are started by /etc/init/rc.conf
#
# Ctrl-Alt-Delete is handled by /etc/init/control-alt-delete.conf
#
# Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf,
# with configuration in /etc/sysconfig/init.
#
# For information on how to write upstart event handlers, or how
# upstart works, see init(5), init(8), and initctl(8).
#
# Default runlevel. The runlevels used are:
# 0 – halt (Do NOT set initdefault to this)
# 1 – Single user mode
# 2 – Multiuser, without NFS (The same as 3, if you do not have networking)
# 3 – Full multiuser mode
# 4 – unused
# 5 – X11
# 6 – reboot (Do NOT set initdefault to this)
#
id:5:initdefault:

เปลี่ยน id:5:initdefault:
เป็น id:3:initdefault:

mtop เอาไว้ monitor การทำงานของ MySQL ครับ

ปล. สำหรับ 64bit server นะครับ

โจทย์ไม่ยาก ไม่ง่าย … แค่ไม่เคยทำ

ความต้องการ

1. dhcp server บน CentOS6
2. แจก ip-address บน subnet ตามต้องการ
3. มี switch layer 2 เป็นตัวแยก vlan

ิวิธีทำ

1. สร้าง vlan id ใน switch ก่อน
ตัวอย่าง

2. ติดตั้ง dhcp server , vconfig

# yum install dhcp vconfig -y

3. load module 802.1q

# modprobe 8021q

check :

# lsmod | grep 8021q
8021q                  19587  0 
garp                    5901  1 8021q

4. สร้าง vlan interfaces

# cat /etc/sysconfig/network-scripts/ifcfg-eth0.2
DEVICE="eth0.2"
ONBOOT="yes"
BOOTPROTO=none
VLAN="yes"
IPADDR=10.156.3.2
NETMASK=255.255.255.0

# cat /etc/sysconfig/network-scripts/ifcfg-eth0.3
DEVICE="eth0.3"
ONBOOT="yes"
BOOTPROTO=none
VLAN="yes"
IPADDR=10.156.4.2
NETMASK=255.255.255.0

# cat /etc/sysconfig/network-scripts/ifcfg-eth0.4
DEVICE="eth0.4"
ONBOOT="yes"
BOOTPROTO=none
VLAN="yes"
IPADDR=10.156.5.2
NETMASK=255.255.255.0

# cat /etc/sysconfig/network-scripts/ifcfg-eth0.5
DEVICE="eth0.5"
ONBOOT="yes"
BOOTPROTO=none
VLAN="yes"
IPADDR=10.156.6.2
NETMASK=255.255.255.0

# cat /etc/sysconfig/network-scripts/ifcfg-eth0.6
DEVICE="eth0.6"
ONBOOT="yes"
BOOTPROTO=none
VLAN="yes"
IPADDR=10.156.7.2
NETMASK=255.255.255.0

# cat /etc/sysconfig/network-scripts/ifcfg-eth0.7
DEVICE="eth0.7"
ONBOOT="yes"
BOOTPROTO=none
VLAN="yes"
IPADDR=10.156.9.2
NETMASK=255.255.255.0

# cat /etc/sysconfig/network-scripts/ifcfg-eth0.8
DEVICE="eth0.8"
ONBOOT="yes"
BOOTPROTO=none
VLAN="yes"
IPADDR=10.156.11.2
NETMASK=255.255.255.0

# cat /etc/sysconfig/network-scripts/ifcfg-eth0.9
DEVICE="eth0.9"
ONBOOT="yes"
BOOTPROTO=none
VLAN="yes"
IPADDR=10.156.13.2
NETMASK=255.255.255.0

5. สร้าง /etc/dhcp/dhcpd.conf
