4, modify the main configuration file (the named.conf)

[root@localhost ~]# vim /etc/named.conf 
options {
                                listen-on port 53 { any; };          ##监听所有

[root@localhost ~]# cd /var/named/  
[root@localhost named]# cp -p named.localhost accp.com.zone    ##复制模板
[root@localhost named]# vim accp.com.zone    ##修改区域配置文件

$TTL 1D
@       IN SOA  @ rname.invalid. (
                                                                        1D      ; refresh

www IN  A       192.168.13.144     ##本机地址
[root@localhost named]# systemctl start named      ##开启dns服务
[root@localhost named]# systemctl stop firewalld.service    ##关闭防火墙
[root@localhost named]# setenforce 0
[root@localhost named]# systemctl start nginx   ##开启nginx服务
[root@localhost named]# netstat -ntap | grep nginx  ##查看端口
tcp   0    0 0.0.0.0:80      0.0.0.0:*       LISTEN   4093/nginx: master 

7, with the test machine test page

8, modify the configuration file, set the domain name to jump

[root@localhost named]# vim /etc/nginx/conf.d/default.conf  ##修改配置文件

        server_name  www.accp.com;

        #charset koi8-r;
        access_log  /var/log/nginx/www.accp.com-access.log  main;

        location / {
                if ($host = "www.accp.com"){        ##匹配如果域名是老域名
                                rewrite ^/(.*)$ http://www.kgc.com/$1 permanent;   ##则永久设置跳转新域名
                }
                root   /usr/share/nginx/html;
                index  index.html index.htm;
        }

9, add a new DNS

[root@localhost named]# vim /etc/named.rfc1912.zones 

zone "kgc.com" IN {
                                type master;
                                file "kgc.com.zone";             ##accp区域数据配置文件
                                allow-update { none; };
};

[root@localhost named]# cp -p /var/named/accp.com.zone /var/named/kgc.com.zone
##复制区域数据配置文件为kgc的数据配置文件
[root@localhost named]# systemctl restart named   ##重启解析服务
[root@localhost named]# systemctl restart nginx     ##重启nginx服务

10, with the old domain name to access, view Jump

Are there parameters 11, after the old domain name plus the parameters, see the jump a new domain name

2-- scenarios based on the client IP Access Jump

公司业务版本上线，所有IP访问任何内容都显示一个固定维护页面，只有公司IP访问正常

1, modify the default configuration file Nginx

[root@localhost ~]# cd /etc/nginx/conf.d/
[root@localhost conf.d]# vim default.conf

        #charset koi8-r;
        access_log  /var/log/nginx/www.accp.com-access.log  main;
        #设置是否合法的IP标志
        set $rewrite true;         ##设置变量为真
        #判断是否为合法的IP
        if ($remote_addr = "192.168.13.140"){
                set $rewrite false;    ##匹配合法IP，将变量设置为假，正常跳转页面
        }
        #非法IP进行判断打上标记
        if ($rewrite = true){                ##匹配非法IP，跳转到main的网页
                rewrite (.+) /main.html;
        }
        #匹配标记进行跳转站点
        location = /main.html {              ##精确匹配
                root /usr/share/nginx/html;   ##站点路径
        }

        location / {
                root   /usr/share/nginx/html;
                index  index.html index.htm;
        }  

2, create a web page and main site of illegal IP

[root@localhost conf.d]# cd /usr/share/nginx/html/  ##切换到站点中
[root@localhost html]# vim main.html    ##编辑非法IP访问网页内容
<h1>this is test web</h1>
[root@localhost html]# systemctl restart nginx   ##重启Nginx服务

3, visit the page

3-- scenarios based on the old, the new domain name and add a table of contents to jump

        #charset koi8-r;
        access_log  /var/log/nginx/www.accp.com-access.log  main;
        location /post {          ##用location匹配post目录
                rewrite (.+) http://www.accp.com/bbs$1 permanent;   ##永久重定向跳转
        }

2, modify dns area data profile (accp.com.zone)

[root@localhost conf.d]# cd /var/named/

                                                    0       ; serial
                                                    1D      ; refresh

                A       127.0.0.1
bbs IN  A       192.168.13.144
[root@localhost named]# systemctl restart named   ##重启解析服务
[root@localhost named]# systemctl restart nginx     ##重启Nginx服务
[root@localhost named]# echo "nameserver 192.168.13.144" > /etc/resolv.conf 
##将解析服务器地址放到本地解析配置文件中
