nginx里的rewrite跳转的实现
一. 新旧域名跳转
作用场景:基于域名的跳转，现在公司旧域名：www.peihua.com
有业务需求要变更，需要使用新域名www.zhenguo.com代替，但是旧域名不能废除。需要跳转到新域名上，而且后面的参数保持不变
配置dns，分别配置www.peihua.com(old)和www.zhenguo.com(new)解析
rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
(必须要有官方源才能yum安装nginx)
yum install nginx -y rpm -qc nginx //查找配置文件
修改nginx的配置文件
[root@localhost ~]# vim /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name www.peihua.com; #域名修改
#charset koi8-r;
access_log /var/log/nginx/peihua.com-access.log main; #日志修改
location / {
#域名重定向
if ($host = 'www.peihua.com') {
rewrite ^/(.*)$ http://www.zhenguo.com/$1 permanent;
}
root /usr/share/nginx/html;
index index.html index.htm;
}
[root@localhost named]# systemctl restart nginx
配置域名解析
yum -y install bind
#修改主配置文件
[root@localhost conf.d]# vim /etc/named.conf
options {
listen-on port 53 { any; }; //修改成any
listen-on-v6 port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
recursing-file "/var/named/data/named.recursing";
secroots-file "/var/named/data/named.secroots";
allow-query { any; }; //修改成any
#修改区域配置文件
[root@localhost conf.d]# vim /etc/named.rfc1912.zones
zone "peihua.com" IN {
type master;
file "peihua.com.zone";
allow-update { none; };
};
zone "zhenguo.com" IN {
type master;
file "zhenguo.com.zone";
allow-update { none; };
};
#修改区域数据文件
[root@localhost conf.d]# cd /var/named/
[root@localhost named]# cp -p named.localhost peihua.com.zone
[root@localhost named]# cp -p peihua.com.zone zhenguo.com.zone
[root@localhost named]# systemctl start named
浏览器测试
浏览器输入模拟访问 http://www.peihua.com/test/1/index.php(虽然这个请求内容) 是不存在的）跳转到
http://www.zhneguo.com/test/1/index.php,从headers 里面 可以看到301，实现了永久跳转，而且域名后的参数也正常跳转。
二. 基于IP访问跳转
作用场景：基于客户端IP访问跳转，例如今天公司业务版本上线，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：12.0.0.100访问正常
修改nginx配置文件
[root@localhost html]# vim /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name www.peihua.com;
#charset koi8-r;
charset 'utf-8'; //识别中文字符
access_log /var/log/nginx/peihua.com-access.log main;
#设置是否合法的IP标志
set $rewrite ture;
#判断是否为合法IP
if ($remote_addr = "12.0.0.100") {
set $rewrite false;
}
#非法IP进行判断打上标记
if ($rewrite = ture) {
rewrite (.+) /maintenance.html;
}
#匹配标记进行跳转站点
location = /maintenance.html {
root /usr/share/nginx/html;
}
给maintenance.html添加自定义页面内容
[root@localhost html]# cat /usr/share/nginx/html/maintenance.html <h1>网站正在维护</h1>
浏览器测试
使用ip地址为12.0.0.100 进行访问http://www.peihua.com,可以正常访问
使用IP地址为12.0.0.99进行访问http://www.peihua.com,显示维护页面
三. 基于旧域名跳转到新域名后面加目录
作用场景：基于旧域名跳转到新域名后面加目录，例如现在访问的是http://bbs.peihua.com.
现在需要将这个域名下面的发帖都跳转到http://www.peihua.com/bbs,注意保持域名跳转后 的参数不变
修改nginx配置文件
[root@localhost named]# vim /etc/nginx/conf.d/default.conf
listen 80;
server_name bbs.peihua.com;
#charset koi8-r;
charset 'utf-8';
access_log /var/log/nginx/peihua.com-access.log main;
location /post {
rewrite (.+) http://www.peihua.com/bbs$1 permanent;
}
注意：accp.com.zone 需要更改主机域名解析，把www改成 bbs
[root@localhost named]# cd /var/named
[root@localhost named]# vim peihua.com.zone
$TTL 1D
@ IN SOA @ rname.invalid. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS @
A 127.0.0.1
bbs IN A 12.0.0.25
[root@localhost named]# systemctl restart named
[root@localhost named]# systemctl restart nginx
浏览器访问
浏览器访问 http://bbs.peihua.com/post/a.html,被跳转称为www.peihua.com/bbs/post/a.txt
四. 基于参数匹配的跳转
作用场景：基于参数匹配的跳转，例如现在访问 http://www.peihua.com/100-(100 | 200)-100.html
跳转到http://www.peihua.com页面
修改nginx配置文件
[root@localhost named]# vim /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name www.peihua.com;
#charset koi8-r;
charset 'utf-8';
access_log /var/log/nginx/peihua.com-access.log main;
if ($request_uri ~ ^/100-(100|200)-(\d+).html$) {
rewrite (.*) http://www.peihua.com permanent;
}
注意：\d匹配一个数字，0~9之间
修改会dns,把bbs改成www
[root@localhost named]# vim peihua.com.zone
$TTL 1D
@ IN SOA @ rname.invalid. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS @
A 127.0.0.1
www IN A 12.0.0.25
[root@localhost named]# systemctl restart named
[root@localhost named]# systemctl restart nginx
浏览器测试
浏览器访问 http://www.peihua.com/100-200-26.html,被跳转称为 www.peihua.com首页
五. 基于所有以php结尾及基于某一个页面的跳转
修改nginx配置文件
[root@localhost named]# vim /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name www.peihua.com;
#charset koi8-r;
charset 'utf-8';
access_log /var/log/nginx/peihua.com-access.log main;
location ~* /upload/.*\.php$ {
rewrite (.+) http://www.peihua.com permanent;
}
[root@localhost named]# systemctl restart nginx
浏览器访问
浏览器访问 http://www.peihua.com/upload/a.php,被跳转称为 www.peihua.com
六. 基于具体的某一个页面进行跳转/abc/123.html
修改nginx配置文件
[root@localhost named]# vim /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name www.peihua.com;
#charset koi8-r;
charset 'utf-8';
access_log /var/log/nginx/peihua.com-access.log main;
location ~* ^/abc/123.html {
rewrite (.+) http://www.peihua.com permanent;
}
[root@localhost named]# systemctl restart nginx
浏览器访问
浏览器访问 http://www.peihua.com/abc/123.html,被跳转称为 www.peihua.com
