9-2 讓資料庫可以讓別的主機連線
10. 修改網卡及ip等資訊
如果主機要換IP，或者這是做好的虛擬機檔案，想要複製在開另一臺機器，那必然會遇到改IP的需求。
先找出有啟動的網卡，如 eth0
ifconfig -a
修改網卡及ip等資訊
vi /etc/network/interfaces
底下的IP、閘道器、DNS...等請自行視情況修改
auto lo eth0
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet static
address 120.115.2.90
netmask 255.255.255.0
network 120.115.2.0
broadcast 120.115.2.255
gateway 120.115.2.253
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 163.26.1.1
dns-search tn.edu.tw
iface eth0 inet6 static
address 2001:288:7201:2::90
netmask 64
gateway 2001:288:7201:2::fffe
更簡易的寫法：
auto lo eth0
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet static
address 120.115.2.90/24
gateway 120.115.2.253
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 163.26.1.1
dns-search tn.edu.tw
iface eth0 inet6 static
address 2001:288:7201:2::90
netmask 64
gateway 2001:288:7201:2::fffe
修改 /etc/hosts（一樣請自行修改IP及網址）
vi /etc/hosts
127.0.0.1 localhost 120.115.2.90 campus-xoops.tn.edu.tw # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters
修改hostname
vi /etc/hostname
將內容改為主機名稱，如：campus-xoops，接著在手動改一下（立即呈現）
hostname campus-xoops
查詢主機版本以及hostname
uname -a
修改DNS設定
vi /etc/resolv.conf
search campus-xoops.tn.edu.tw nameserver 163.26.1.1
重啟網路
service networking restart
這樣IP就改好了！
