一 配置机器启动方式
命令:vi /etc/inittab
[root@localhost puppet]# vi /etc/inittab # inittab is only used by upstart for the default runlevel. # # ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM. # # 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: |
注:
- id:3 :命令模式启动
- id:5 :XWindows启动
重启生效
二修改机器名
命令:vi /etc/sysconfig/network
[root@AY131216151615898d19Z ~]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=dc-fetch-000 【机器名】 |
注:
- NETWORKING=yes:表示系统是否使用网络,一般设置为yes。如果设为no,则不能使用网络,而且很多系统服务程序将无法启动
- HOSTNAME=centos:设置本机的主机名,这里设置的主机名要和/etc/hosts中设置的主机名对应
重启生效
三 修改网络
(一)网络服务
1 重启网络服务器
命令: service network restart 或 /etc/init.d/network restart
[root@BigData-01 puppet]# service network restart Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: Active connection state: activated Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/2 [ OK ] |
2 开启关闭防火墙
命令: service iptables start , service iptables stop , service iptables restart
[root@localhost ailk]# service iptables status iptables: Firewall is not running. [root@localhost ailk]# service iptables Usage: iptables {start|stop|restart|condrestart|status|panic|save} |
(二)网络环境
1 主机IP映射
命令:vi /etc/hosts
[root@BigData-01 puppet]# vi /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 8.8.8.10 BigData-01 ZK-01 |
注:
- 第一部份:网络IP地址;
- 第二部份:
- 主机名.域名,注意主机名和域名之间有个半角的点,比如 localhost.localdomain
- 主机名(主机名别名) ,其实就是主机名;
及时生效
2 静态IP设置
命令: cd /etc/sysconfig/network-scripts/
vi ifcfg-eth0
[root@localhost sysconfig]# cd /etc/sysconfig/network-scripts/ [root@localhost network-scripts]# vi ifcfg-eth0 DEVICE="eth0" BOOTPROTO="static" IPADDR="8.8.8.2" NETMASK="255.255.255.0" NETWORK="8.8.8.0" #HWADDR="00:0C:29:8E:42:B2"
GATEWAY="8.8.8.1"
ONBOOT="yes"
|
注:
- DEVICE=eth0:描述网卡对应的设备别名,例如ifcfg-eth0的文件中它为eth0
- BOOTPROTO=static:设置网卡获得ip地址的方式,可能的选项为static,dhcp或bootp,分别对应静态指定的 ip地址,通过dhcp协议获得的ip地址,通过bootp协议获得的ip地址
- BROADCAST=192.168.0.255:对应的子网广播地址
- HWADDR=00:07:E9:05:E8:B4:对应的网卡物理地址
- IPADDR=12.168.0.33:如果设置网卡获得 ip地址的方式为静态指定,此字段就指定了网卡对应的ip地址
- NETMASK=255.255.255.0:网卡对应的网络掩码
- NETWORK=192.168.0.0:网卡对应的网络地址
- GATEWAY=192.168.0.1:设置本机连接的网关的IP地址
重启网络服务生效
3 设置DNS
命令:
[root@BigData-01 puppet]# vi /etc/resolv.conf # Generated by NetworkManager # No nameservers found; try putting DNS servers into your # ifcfg files in /etc/sysconfig/network-scripts like so: # # DNS1=xxx.xxx.xxx.xxx # DNS2=xxx.xxx.xxx.xxx # DOMAIN=lab.foo.com bar.foo.com |
注:
DNS1 即是DNS服务器IP地址,第一个是首选,第二个是备用
