CentOS 7安装主从DNS服务和配置Apache服务器

一、安装主DNS服务器

1、配置主DNS

[root@centos01 ~]# yum -y install bind bind-chroot bind-utils    [root@centos01 ~]# cp /etc/named.conf /etc/named.conf.bak   [root@centos01 ~]# echo "" > /etc/named.conf       options{                  listen-on   port    53  { any; };          directory "/var/named";           };zone    "benet.com" IN  {              type    master;                           file    "benet.com.zone";              allow-transfer { 192.168.100.20; };       };zone    "accp.com"  IN  {    type    master;    file    "accp.com.zone";    allow-transfer  { 192.168.100.20; };};[root@centos01 ~]# named-checkconf -z /etc/named.conf  

2、配置benet区域的正向解析区域

[root@centos01 ~]# vim /var/named/benet.com.zone  $TTL    86400         @   SOA benet.com.  root.benet.com(           2020020910             1H                 15M                  1W               1D             )@   NS  centos01.benet.com.     NS  centos02.benet.com.              centos01 A  192.168.100.10        centos02 A  192.168.100.20        ftp  A  192.168.100.10           www A  192.168.100.10          [root@centos01 ~]# named-checkzone benet.com /var/named/benet.com.zone  zone benet.com/IN: loaded serial 2020020910OK[root@centos01 ~]# chmod 755 /var/named/benet.com.zone             [root@centos01 ~]# chown named:named /var/named/benet.com.zone                       

3、配置accp区域的正向解析区域

[root@centos01 ~]#cp /var/named/benet.com.zone  /var/named/accp.com.zone     [root@centos01 ~]# vim /var/named/accp.com.zone          $TTL    86400 @   SOA accp.com.   root.accp.com(    2020020910    1H    15M    1W    1D)@   NS  centos01.accp.com.             NS  centos02.accp.com.         centos01 A  192.168.100.10       ftp  A  192.168.100.10            www A  192.168.100.10          [root@centos01 ~]# named-checkzone accp.com /var/named/accp.com.zone              zone accp.com/IN: loaded serial 2020020910OK

4、启动DNS服务

[root@centos01 ~]# systemctl start named            [root@centos01 ~]# systemctl enable named       

5、网卡添加DNS

[root@centos01 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens32            DNS1=192.168.100.20                DNS2=192.168.100.10                  [root@centos01 ~]# systemctl restart network      [root@centos01 ~]# systemctl restart named     

二、安装从DNS服务器

1、配置从DNS

[root@centos02 ~]# yum -y install bind bind-chroot bind-utils[root@centos02 ~]# cp /etc/named.conf /etc/named.conf.bak[root@centos02 ~]# echo "" > /etc/named.conf[root@centos02 ~]# vim /etc/named.confoptions {    listen-on   port    53  { any; };    directory   "/var/named";};zone    "benet.com" IN  {    type    slave;    file    "slaves/benet.com.zone";    masters { 192.168.100.10; };};zone    "accp.com"  IN  {    type    slave;    file    "slaves/accp.com.zone";    masters { 192.168.100.10; };};

2、启动DNS服务

[root@centos02 ~]# systemctl start named[root@centos02 ~]# systemctl enable named

3、检测从是否自动复制主的配置文件

[root@centos02 ~]# cd /var/named/[root@centos02 named]# lschroot  data  dynamic  named.ca  named.empty  named.localhost  named.loopback  slaves[root@centos02 named]# cd slaves/[root@centos02 slaves]# lsaccp.com.zone  benet.com.zone

4、网卡添加DNS

[root@centos02 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens32DNS1=192.168.100.10DNS2=192.168.100.20[root@centos02 ~]# systemctl restart network[root@centos02 ~]# systemctl restart named

5、测试DNS解析

1）主DNS测试解析

[root@centos01 ~]# nslookup ftp.benet.comServer:     192.168.100.20Address:    192.168.100.20#53Name:   ftp.benet.comAddress: 192.168.100.10

2）客户端测试解析

3）备用DNS测试解析

[root@centos02 ~]# nslookup ftp.accp.comServer:     192.168.100.10Address:    192.168.100.10#53Name:   ftp.accp.comAddress: 192.168.100.10

三、配置基于域名的Apache服务器

1、安装配置Apache

[root@centos01 ~]# tar zxvf /mnt/httpd-2.2.17.tar.gz -C /usr/src/ [root@centos01 ~]# cd /usr/src/httpd-2.2.17/[root@centos01 httpd-2.2.17]# ./configure --prefix=/usr/local/httpd--enable-so --enable-rewrite -enable-charset-lite --enable-cgi         [root@centos01 httpd-2.2.17]# make && make install [root@centos01 ~]# ln -s /usr/local/httpd/bin/* /usr/local/bin/ [root@centos01 ~]# cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd           [root@centos01 ~]# chmod +x /etc/init.d/httpd  [root@centos01 ~]# vim /etc/init.d/httpd  #chkconfig:35 80 20 [root@centos01 ~]# chkconfig --add httpd [root@centos01 ~]# chkconfig --level 35 httpd on[root@centos01 ~]# systemctl start httpd  

2、配置虚拟主机

[root@centos01 ~]# mkdir /var/www      [root@centos01 ~]# mkdir /var/www/benetcom [root@centos01 ~]# mkdir /var/www/accpcom[root@centos01 ~]# echo "www.benet.com" >  /var/www/benetcom/index.html         [root@centos01 ~]# echo "www.accp.com" >   /var/www/accpcom/index.html         [root@centos01 ~]# vim /usr/local/httpd/conf/httpd.conf            98 ServerName 192.168.100.10:80 389 Include conf/extra/httpd-vhosts.conf [root@centos01 ~]# vim /usr/local/httpd/conf/extra/httpd-vhosts.conf        NameVirtualHost 192.168.100.10:80               Order   allow,deny        allow   from    all           DocumentRoot "/var/www/benetcom/"       ServerName www.benet.com                 CustomLog "logs/www.benet.com_access_log" common                         DocumentRoot "/var/www/accpcom/"    ServerName www.accp.com    CustomLog "logs/www.accp.com_access_log" common[root@centos01 ~]# systemctl restart httpd [root@centos01 ~]# httpd -t Syntax OK 

3、客户端访问测试
