一. 新舊域名跳轉(zhuǎn)
作用場(chǎng)景:基于域名的跳轉(zhuǎn)，現(xiàn)在公司舊域名：www.peihua.com
有業(yè)務(wù)需求要變更，需要使用新域名www.zhenguo.com代替，但是舊域名不能廢除。需要跳轉(zhuǎn)到新域名上，而且后面的參數(shù)保持不變
配置dns，分別配置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
(必須要有官方源才能yum安裝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
#修改區(qū)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; };
};
#修改區(qū)域數(shù)據(jù)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
瀏覽器測(cè)試
瀏覽器輸入模擬訪問(wèn) http://www.peihua.com/test/1/index.php(雖然這個(gè)請(qǐng)求內(nèi)容) 是不存在的）跳轉(zhuǎn)到
http://www.zhneguo.com/test/1/index.php,從headers 里面 可以看到301，實(shí)現(xiàn)了永久跳轉(zhuǎn)，而且域名后的參數(shù)也正常跳轉(zhuǎn)。
二. 基于IP訪問(wèn)跳轉(zhuǎn)
作用場(chǎng)景：基于客戶端IP訪問(wèn)跳轉(zhuǎn)，例如今天公司業(yè)務(wù)版本上線，所有IP 訪問(wèn)任何內(nèi)容都顯示一個(gè)固定維護(hù)頁(yè)面，只有公司IP：12.0.0.100訪問(wèn)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'; //識(shí)別中文字符
access_log /var/log/nginx/peihua.com-access.log main;
#設(shè)置是否合法的IP標(biāo)志
set $rewrite ture;
#判斷是否為合法IP
if ($remote_addr = "12.0.0.100") {
set $rewrite false;
}
#非法IP進(jìn)行判斷打上標(biāo)記
if ($rewrite = ture) {
rewrite (.+) /maintenance.html;
}
#匹配標(biāo)記進(jìn)行跳轉(zhuǎn)站點(diǎn)
location = /maintenance.html {
root /usr/share/nginx/html;
}
給maintenance.html添加自定義頁(yè)面內(nèi)容
[root@localhost html]# cat /usr/share/nginx/html/maintenance.html
<h1>網(wǎng)站正在維護(hù)</h1>
瀏覽器測(cè)試
使用ip地址為12.0.0.100 進(jìn)行訪問(wèn)http://www.peihua.com,可以正常訪問(wèn)
使用IP地址為12.0.0.99進(jìn)行訪問(wèn)http://www.peihua.com,顯示維護(hù)頁(yè)面
三. 基于舊域名跳轉(zhuǎn)到新域名后面加目錄
作用場(chǎng)景：基于舊域名跳轉(zhuǎn)到新域名后面加目錄，例如現(xiàn)在訪問(wèn)的是http://bbs.peihua.com.
現(xiàn)在需要將這個(gè)域名下面的發(fā)帖都跳轉(zhuǎn)到http://www.peihua.com/bbs,注意保持域名跳轉(zhuǎn)后 的參數(shù)不變
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 需要更改主機(jī)域名解析，把www改成 bbs
[root@localhost named]# cd /var/named
[root@localhost named]# vim peihua.com.zone
$TTL 1D
@ IN SOA @ rname.invalid. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS @
A 127.0.0.1
bbs IN A 12.0.0.25
[root@localhost named]# systemctl restart named
[root@localhost named]# systemctl restart nginx
瀏覽器訪問(wèn)
瀏覽器訪問(wèn) http://bbs.peihua.com/post/a.html,被跳轉(zhuǎn)稱為www.peihua.com/bbs/post/a.txt
四. 基于參數(shù)匹配的跳轉(zhuǎn)
作用場(chǎng)景：基于參數(shù)匹配的跳轉(zhuǎn)，例如現(xiàn)在訪問(wèn) http://www.peihua.com/100-(100 | 200)-100.html
跳轉(zhuǎn)到http://www.peihua.com頁(yè)面
修改nginx配置文件
[root@localhost named]# vim /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name www.peihua.com;
#charset koi8-r;
charset 'utf-8';
access_log /var/log/nginx/peihua.com-access.log main;
if ($request_uri ~ ^/100-(100|200)-(\d+).html$) {
rewrite (.*) http://www.peihua.com permanent;
}
注意：\d匹配一個(gè)數(shù)字，0~9之間
修改會(huì)dns,把bbs改成www
[root@localhost named]# vim peihua.com.zone
$TTL 1D
@ IN SOA @ rname.invalid. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS @
A 127.0.0.1
www IN A 12.0.0.25
[root@localhost named]# systemctl restart named
[root@localhost named]# systemctl restart nginx
瀏覽器測(cè)試
瀏覽器訪問(wèn) http://www.peihua.com/100-200-26.html,被跳轉(zhuǎn)稱為 www.peihua.com首頁(yè)
五. 基于所有以php結(jié)尾及基于某一個(gè)頁(yè)面的跳轉(zhuǎn)
修改nginx配置文件
[root@localhost named]# vim /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name www.peihua.com;
#charset koi8-r;
charset 'utf-8';
access_log /var/log/nginx/peihua.com-access.log main;
location ~* /upload/.*\.php$ {
rewrite (.+) http://www.peihua.com permanent;
}
[root@localhost named]# systemctl restart nginx
瀏覽器訪問(wèn)
瀏覽器訪問(wèn) http://www.peihua.com/upload/a.php,被跳轉(zhuǎn)稱為 www.peihua.com
六. 基于具體的某一個(gè)頁(yè)面進(jìn)行跳轉(zhuǎn)/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
瀏覽器訪問(wèn)
瀏覽器訪問(wèn) http://www.peihua.com/abc/123.html,被跳轉(zhuǎn)稱為 www.peihua.com
