nginx访问控制，用户认证，https

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比如：allow 192.168.100.20  192.168.100.30;deny all;拒绝某台主机访问nginx状态页面location /status {echo "hello";deny 192.168.100.20;}

 此时使用192.168.100.20来访问

此时是拒绝访问

使用192.168.100.30来访问

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location /status {echo "hello";stub_status on;}

访问

 

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Header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。

 当allow和deny同时存在时

  location /status {stub_status on;allow 192.168.100.20;deny all;

使用192.168.100.20来访问

使用192.168.100.30来访问

拒绝访问

 默认访问权限是allow all，所有用户均可访问

1、只允许指定得ip访问，禁止其他ip访问allow 192.168.100.11;allow 192.168.100.12;deny all;2、只禁止指定的ip访问，允许其他ip访问deny 192.168.100.11;deny 192.168.100.12;allow all;

 用户认证

auth_basic “欢迎信息”;
auth_basic_user_file  “/path/to/user_auth_file”;
//user_auth_file内容格式
username:password//这里的密码为加密后的密码串，建议用htpasswd来创建文件
htpasswd -c -m /path/to/.user_auth_file USERNAME//授权用户
安装httpd-tools软件包
[root@nginx ~]# yum -y install httpd-tools//创建用户密钥文件
[root@nginx ~]# cd /usr/local/nginx/conf/
[root@nginx conf]# htpasswd -c -m .user_auth_file chen
New password: 
Re-type new password: 
Adding password for user chen
[root@nginx conf]# cat .user_auth_file 
chen:$apr1$whXqcpS.$EORacQbsq0P6JblZ0ayM5///配置nginx（注意auth_basic_user_file必须用绝对路径）
[root@nginx conf]# vim nginx.conflocation /status {stub_status on;auth_basic "welcome to hyedu";auth_basic_user_file "/usr/local/nginx/conf/.user_auth_file";}//ngint -t 测试配置文件并重载配置文件
[root@nginx conf]# 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@nginx conf]# nginx -s reload

Nginx：192.168.100.10

CA：192.168.100.30
