CentOS DNS配置

Linux 下设置DNS位置有3处，其生效顺序如下：

  • /etc/hosts
  • 网卡配置文件DNS服务器地址
  • /etc/resolv.conf

通过设置主机表地址进行特定主机的解析，优先DNS服务器地址，/etc/hosts：

1
2
3
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
123.125.114.144 www.baidu.com #手动指定百度的IP

在/etc/hosts配置www.baidu.com的网址后，可以用ping www.baidu.com命令来观看ping的地址是否是123.125.114.114

Linux中默认的DNS服务器地址配置文件为/etc/resolv.conf:

1
2
nameserver 114.114.114.114 #配置DNS服务器地址，可配置多个
nameserver 8.8.8.8

在网卡配置文件中添加DNS服务器地址， /etc/sysconfig/network-scripts/ifcfg-eno16777736：

1
2
DNS1=114.114.114.114
DNS2=8.8.8.8

CentOS网络配置

根据centos7.0安装教程安装虚拟机。

su root切换到root用户，编辑配置文件vim /etc/sysconfig/network-scripts/ifcfg-eno16777736

注意配置能够使用的DNS，否则无法解析域名，可参考常用公共DNS服务器地址

service network restart重启网络

ping baidu.com是否能够ping通百度

时间配置

配置本地时区：
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
同步网络时间：
yum install ntpdate
ntpdate pool.ntp.org

Samba服务配置

yum install samba samba-client samba-common安装相关软件

# rpm -qa | grep samba
samba-4.1.12-23.el7_1.x86_64
samba-libs-4.1.12-23.el7_1.x86_64
samba-common-4.1.12-23.el7_1.x86_64
samba-client-4.1.12-23.el7_1.x86_64

这里顺便说一下搭建samba服务器所需要的基本软件包：

  1. samba 这个软件包包含了主要的daemon文件（smbd和nmbd）
  2. samba-common 提供samba的主要配置文件(smb.conf)、smb.conf语法检测程序(testparm)等
  3. samba-client 当linux作为samba 客户端的时候，提供了一套所需的工具和指令。

备份配置文件cp /etc/samba/smb.conf /etc/samba/smb.conf.$(date +%F)
编辑vim /etc/samba/smb.conf

	cups options = raw

[samba]
	comment = my share dir
	path = /home/user
	browseable = yes
	guest ok = yes

添加用户smbpasswd -a samba_user,设置密码
重启服务
service smb restart
service nmb restart

关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service
setenforce 0

Linux下客户端测试
smbclient -L //192.168.0.122/samba -U samba_user

设置开机启动
systemctl enable smb.service

Win8下添加网络位置
进入我的电脑，【右击】-【添加网络位置】根据向导一直点击【下一步】，在Internet地址或网络位置下填写\\192.168.0.122\samba,【下一步】根据提示填写用户与密码。
