nginx rewrite

应用场景1——基于域名的跳转

公司旧域名 ,因业务需求有变更,需要使用新域名www.kgc.com 代替

1.不能废除旧域名
2.从旧域名跳转到新域名,且保持其参数不变

部署环境

一台linux服务器(192.168.142.130)
一台测试主机windows 7

1,安装nginx服务

[root@localhost ~]# rpm -uvh http://nginx.org/packages/centos/7/noarch/rpms/nginx-release-centos-7-0.el7.ngx.noarch.rpm
#安装nginx官方源

[root@localhost ~]# yum install nginx -y  
#yum安装nginx
Copy after login

2,修改nginx默认配置文件

[root@localhost ~]# vim /etc/nginx/conf.d/default.conf ##修改默认配置文件
server {
    listen    80;
    server_name www.accp.com;  ##修改主机名

    #charset koi8-r;
    access_log /var/log/nginx/www.accp.com-access.log main;  ##开启日志服务
Copy after login

3,安装bind解析服务

[root@localhost ~]# yum install bind -y
Copy after login

4,修改主配置文件(named.conf)

[root@localhost ~]# vim /etc/named.conf 
options {
                listen-on port 53 { any; };     ##监听所有
                ...
                allow-query   { any; };      ##允许所有
Copy after login

[root@localhost ~]# vim /etc/named.rfc1912.zones  ##配置区域配置文件

zone "accp.com" in {
                type master;
                file "accp.com.zone";       ##accp区域数据配置文件
                allow-update { none; };
};
Copy after login

6,修改区域数据配置文件(accp.com.zone)

[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
                                    1h   ; retry

                ns   @
                a    127.0.0.1
www in a    192.168.142.130         ##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
Copy after login

      #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;
      }
Copy after login

                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

    #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 = "192.168.142.120"){
        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;
    }
Copy after login
