一、www.a.com -> www.b.com
1、目标：当在网页中输入www.a.com时，自动跳转到www.b.com。
2、操作步骤：
(1) 安装nginx，保证nginx能够正常访问
(2) 修改nginx的配置文件
(3) 重启nginx服务
(4) 浏览器测试
3、操作流程
关闭防火墙以及linux安全机制
[root@localhost ~]# systemctl stop firewalld [root@localhost ~]# iptables -F [root@localhost ~]# setenforce 0
在nginx正常访问的情况下，修改配置文件
[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf if ($host = "www.b.com") { rewrite ^(.*)$ http://www.a.com/$1 permanent; }
测试语法，重启
[root@localhost ~]# nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@localhost ~]# nginx
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
网页测试（访问www.b.com ，返回www.a.com）
二、www.a.com/a.html -> www.a.com/file/a.html
1、目标：当在网页中输入www.a.com/a.html时，自动跳转到www.a.com/file/a.html
2、操作步骤：
(1) 安装nginx，保证能正常访问
(2) 修改nginx的配置文件
(3) 重启nginx服务
(4) 在/usr/local/nginx/html下创建文件a.html，编写内容“1111111111”
(5) 在/usr/local/nginx/html下创建文件夹file，在file下创建文件a.html，编写内容“22222222”
(6) 浏览器测试
3、操作过程
关闭防火墙以及linux安全机制
[root@localhost ~]# systemctl stop firewalld [root@localhost ~]# iptables -F [root@localhost ~]# setenforce 0
nginx安装完了，修改配置文件
[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf location /a.html { rewrite ^(.*)$ http://www.a.com/file/a.html permanent; }
重启nginx服务
[root@localhost ~]# nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful [root@localhost ~]# nginx nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] still could not bind()
创建文件a.html，编写内容“11111111”
[root@localhost ~]# cd /usr/local/nginx/html/
[root@localhost html]# vim a.html 1111111111
创建文件夹file，在file中创建文件a.html，编写内容“22222222”
[root@localhost ~]# cd /usr/local/nginx/html/ [root@localhost html]# mkdir file [root@localhost html]# ls 50x.html file index.html [root@localhost html]# cd file/ [root@localhost file]# touch a.html [root@localhost file]# vim a.html 22222222
浏览器测试（访问www.a.com/a.html ,返回www.a.com/file/a.html）
