本文主要是介绍nginx访问控制、用户认证、https，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
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：设定禁止那台或哪些主机访问，多个参数间用空格隔开
//deny
[root@nginx ~]# vim /usr/local/nginx/conf/nginx.conflocation /status {echo "lisy";deny 192.168.35.143;}
[root@nginx ~]# nginx -s reload
//验证
[root@test ~]# curl http://192.168.35.142/status
<html>
<head><title>403 Forbidden</title></head>
<body>
<center><h1>403 Forbidden</h1></center>
<hr><center>nginx/1.24.0</center>
</body>
</html>//开启stub_status模块，stub_status模块主要作用于查看nginx的一些状态信息
[root@nginx ~]# vim /usr/local/nginx/conf/nginx.conflocation /status {echo "lisy";stub_status on;}[root@nginx ~]# nginx -s reload
//查看状态信息
[root@test ~]# curl http://192.168.35.142/status
Active connections: 1
server accepts handled requests19 19 19
Reading: 0 Writing: 1 Waiting: 0
//Active connections：当前nginx正在处理的活动连接数
//Server accepts handled requests：nginx总共处理了63个连接，成功创建63次握手，总共处理了62个请求
//Reading：nginx读取到客户端的Header信息数
//Writing：nginx返回给客户端的eader信息数
//Waiting：开启keep-alive的情况下，这个值等于active-（reading+writing），意思就是nginx已经处理完成，正在等候下一次请求指令的驻留连接。所以，在访问效率高、请求很快就被处理完毕的情况下，waiting数比较多是正常的。如果reading+writing数较多，则说明并发访问量非常大，正在处理过程中。//allow和deny同时存在时
[root@nginx ~]# vim /usr/local/nginx/conf/nginx.conflocation /status {echo "lisy";allow 192.168.35.143;deny all;}
[root@nginx ~]# nginx -s reload
//验证
[root@test ~]# curl http://192.168.35.142/status
lisy
[root@test2 ~]# curl http://192.168.35.142/status
<html>
<head><title>403 Forbidden</title></head>
<body>
<center><h1>403 Forbidden</h1></center>
<hr><center>nginx/1.24.0</center>
</body>
</html>用户认证
//安装httpd-tools软件包
[root@nginx ~]# yum -y install httpd-tools//创建用户密钥文件
[root@nginx ~]# htpasswd -c -m /usr/local/nginx/conf/.user_auth_file lsy123
New password:
Re-type new password:
Adding password for user lsy123//配置nginx（注意auth_basic_user_file必须用绝对路径）
[root@nginx conf]# vim nginx.conf
[root@nginx conf]# nginx -s reload验证
https配置
//环境准备
//nginx/example.com 192.168.35.142
//test.example.com 192/168.35.143//tesr主机
//在CA服务器中生成一对密钥
[root@test ~]# mkdir -p /etc/pki/CA/private
[root@test ~]# cd /etc/pki/CA/
[root@test CA]# (umask 077;openssl genrsa -out private/cakey.pem 2048)[root@test CA]# ls
private
[root@test CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 1024
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:HB
Locality Name (eg, city) [Default City]:WH
Organization Name (eg, company) [Default Company Ltd]:huayu
Organizational Unit Name (eg, section) []:linux
Common Name (eg, your name or your server's hostname) []:lsy
Email Address []:lsy@example.com//nginx主机
