nginx-设置默认虚拟主机、设置域名重定向、设置用户认证

Nginx默认虚拟主机

编辑nginx.comf

vim /usr/local/nginx/conf/nginx.conf
删除server段
加入include vhost/*.conf；

    gzip_types text/plain application/x-javascript text/css text/htm
    application/xml;
    include vhost/*.conf;
}

新建vhost目录

mkdir /usr/local/nginx/conf/vhost
cd /usr/local/nginx/conf/vhost/
vim aaa.com.conf

写入代码

server
{
    listen 80 default_server;  // 有这个标记的就是默认虚拟主机
    server_name aaa.com;
    index index.html index.htm index.php;
    root /data/wwwroot/default;
}

创建default网站目录

mkdir /data/wwwroot/default
vim index.html
代码
This is the default test.

检错与重启测试

/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload

curl -x127.0.0.1:80 aaa.com
curl -x127.0.0.1:80 bbb.com

nginx用户认证

编辑web配置文件

cd /usr/local/nginx/conf/vhost/
vim test.com.conf

代码

server
{
    listen 80;
    server_name test.com;
    index index.html index.htm index.php;
    root /data/wwwroot/test.com;
    
location  /
    {
        auth_basic              "Auth";
        auth_basic_user_file   /usr/local/nginx/conf/htpasswd;
}
}

生成密码文件

/usr/local/apache2.4/bin/htpasswd -c /usr/local/nginx/conf/htpasswd admin
注意：如果没有安装apache那么就需要yum install -y httpd
然后htpasswd -c /usr/local/nginx/conf/htpasswd admin

创建test.com目录

mkdir /data/wwwroot/test.com
vim 1.html
输入网页代码This is test.com/1.html

测错与应用配置

/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload

测试

curl -uadmin:admin -x127.0.0.1:80 test.com/1.html
This is test.com/1.html

只针对目录用户认证

vim /usr/local/nginx/conf/vhost/test.com.conf

修改 location / 为location /admin/ 也就是将代表所有的/改为代表目录的/admin/

代码如下

server
{
    listen 80;
    server_name test.com;
    index index.html index.htm index.php;
    root /data/wwwroot/test.com;
location  /admin/
    {
        auth_basic              "Auth";
        auth_basic_user_file   /usr/local/nginx/conf/htpasswd;
}
}

针对单个页面

vim /usr/local/nginx/conf/vhost/test.com.conf

修改 location / 为location ~ admin.php 也就是将代表所有的/改为代表目录的/admin/

---

域名重定向

编辑web配置文件

vim /usr/local/nginx/conf/vhost/test.com.conf

增加

 if ($host != 'test.com' ) {
        rewrite  ^/(.*)$  http://test.com/$1  permanent;
    }

修改server_name 后面增加test1.com

代码预览

server
{
    listen 80;
    server_name test.com test1.com test2.com;
    index index.html index.htm index.php;
    root /data/wwwroot/test.com;
    if ($host != 'test.com' ) {
        rewrite  ^/(.*)$  http://test.com/$1  permanent;
    }
}

检错与重新加载

/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload

测试 访问test1.com定位到test.com上了，成功

curl -x127.0.0.1:80 test1.com/1.html -I
