Web server basics-Nginx web service access authentication

This environment is based on the Centos 7.8 system to build the Nginx learning environment. For
specific construction, please refer to Nginx-1.18.0 Environment Deployment

Nginx rewrite is the same as Apache and other web service software, the main function of Nginx rewrite is to realize URL address rewriting. Nginx's rewrite rules need the support of PCRE software, that is, rule matching is performed through Perl compatible regular expression grammar.

1. Access control based on IP address

[root@node01 ~]# vim /etc/nginx/conf.d/host.conf 
    server {
    
    
        listen       192.168.5.11:80;
        server_name  bbs.123.cn;
        location / {
    
    
            root   /usr/share/nginx/html/bbs;
            index  index.html index.htm;
            deny 192.168.5.12;
            allow 192.168.5.0/24;
            deny all;
        }
}

[root@node01 ~]# nginx -s reload

Physical machine

rhel7

node02

Two, based on user access control

[root@node01 ~]# yum install httpd-tools -y
[root@node01 ~]# htpasswd -c /etc/passwd wan

User Xiaoming failed to access

wan user access successfully

Three, based on file access control

[root@node01 ~]# vim /etc/nginx/conf.d/host.conf 
    server {
    
    
        listen       192.168.5.11:80;
        server_name  bbs.123.cn;
        location / {
    
    
            root   /usr/share/nginx/html/bbs;
            index  index.html index.htm;
        location ~ \.txt{
    
    
            deny all;
           }
        }
}
[root@node01 ~]# nginx -s reload
