nginx访问控制

用于location段
allow：设定允许哪台或哪些主机访问，多个参数间用空格隔开
deny： 设定禁止哪台或哪些主机访问，多个参数间用空格隔开

//测试 [root@nginx ~]# cd /usr/local/nginx/html/ [root@nginx html]# ls 50x.html  index.html [root@nginx html]# echo 'hello world' > index.html  [root@nginx html]# systemctl restart nginx  //虚拟机访问 [root@nginx html]# curl 192.168.111.141 hello world 

访问测试

//修改配置文件 [root@nginx html]# cd .. [root@nginx nginx]# vim conf/nginx.conf         location / {             allow 192.168.111.141;             deny all;             root   html;             index  index.html index.htm;         } [root@nginx nginx]# systemctl restart nginx  //虚拟机访问 [root@nginx nginx]# curl 192.168.111.141 hello world 

访问测试

nginx用户认证

//安装httpd工具包 [root@nginx ~]# yum -y install httpd-tools  //修改配置文件 [root@nginx ~]# cd /usr/local/nginx/conf/ [root@nginx conf]# vim nginx.conf         location / {             root   html;             index  index.html index.htm;         }          location /abc {               auth_basic "ABC";               auth_basic_user_file "/usr/local/nginx/conf/.pass"; 	//密码位置               root html;              index index.html;         }  //生成用户密码 [root@nginx conf]# htpasswd -cm /usr/local/nginx/conf/.pass runtime New password:  Re-type new password:  Adding password for user runtime [root@nginx conf]# cat .pass  runtime:$apr1$nPzAshNM$nvmalzBcNQlagDB3ipABc1		//加密后的密码 [root@nginx conf]# systemctl restart nginx

证书申请及签署步骤

a) 生成申请请求 b) RA核验c) CA签署 d) 获取证书
