Kibana配置nginx反代并本地ca加密nginx

• ELK Stack, Nginx, 代理, 日志分析

简介

我们部署完ELK Stack后,虽然可以直接浏览器访问kibana进行访问,但这样对一些重要数据来说是不安全的,可以利用密码验证设置权限访问,在Kibana所在的服务器上安装Nginx服务，利用Nginx的转发指令实现

部署nginx

rpm -ivh nginx-1.16.0-1.el7.ngx.x86_64.rpm 

配置加密工具htpasswd生成账号和密码

htpasswd -c /etc/nginx/ssl/htpasswd admin
New password: 
Re-type new password: 
Adding password for user admin

配置nginx

cat /etc/nginx/conf.d/kibana.conf 
server {
       listen       80;
       #server_name  kibanaes.com;
       server_name  paidui-kibana.360sides.net;

       access_log  /home/appmanager/data/logs/nginx/kibana_access.log json;
       error_log   /home/appmanager/data/logs/nginx/kibana_error.log;
       location / {
           auth_basic "The Kibana Monitor Center";  
           auth_basic_user_file /etc/nginx/ssl/htpasswd;  
           proxy_pass   //1.1.1.1:5601;
           proxy_http_version 1.1;
           proxy_set_header Host $host;
           proxy_cache_bypass $http_upgrade;
       }
}

重启nginx生效

nginx -s reload

访问验证

配置本地CA生成证书加密nginx

基于https的协议工作的一中虚拟主机，要构建这样的网站需要mod_ssl模块的支持。且需要提供两个文件：证书文件和私钥文件，证书文件是标识这个网站服务器身份的，私钥文件主要用来实现在服务器端对数据进行加密，然后在网站中传输的。证书在生产生活中需要到对应的机构去申请，在实验环境中本应该搭建一台证书服务器，然后由证书服务器给web服务器颁发证书来验证其的身份，但是证书服务器构建是非常麻烦的

生成证书及密钥文件

# 1.准备存放证书和秘钥的目录
mkdir /etc/nginx/ssl
cd /etc/nginx/ssl
 
# 2.使用openssl生成基于rsa数学算法长度为1024bit的秘钥,文件必须以key为结尾
[root@IntelID-Squid-N25 ssl]#  openssl genrsa 1024 > /etc/nginx/ssl/server.key
Generating RSA private key, 1024 bit long modulus
..............++++++
..........++++++
e is 65537 (0x10001)

# 3.使用秘钥文件生成证书申请
[root@IntelID-Squid-N25 ~]# openssl req -new -key /etc/nginx/ssl/server.key > /etc/nginx/ssl/server.csr
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) []:BJ
Locality Name (eg, city) [Default City]:BJ
Organization Name (eg, company) [Default Company Ltd]:dx
Organizational Unit Name (eg, section) []:paidui-kibana.360sides.net
Common Name (eg, your name or your server's hostname) []:paidui-kibana.360sides.net
Email Address []:18621048481@163.com

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

# 4. 同意申请，生成证书
[root@IntelID-Squid-N25 ~]# openssl req -x509 -days 365 -key /etc/nginx/ssl/server.key -in /etc/nginx/ssl/server.csr > /etc/nginx/ssl/server.crt

# -x509：证书的格式，固定的
# days：证书的有效期
# key：指定秘钥文件
# in：指定证书申请文件

配置私有CA的https

[root@IntelID-Squid-N25 conf.d]# cat /etc/nginx/conf.d/kibana.conf 
server {
       listen       80;
       server_name  xxxx.net;
       return 301 //xxxxxx$request_uri;
}

server {
      listen 443 ssl;
      ssl on;
      ssl_certificate /etc/nginx/ssl/server.crt;
      ssl_certificate_key /etc/nginx/ssl/server.key;
      access_log  /home/appmanager/data/logs/nginx/kibana_access.log json;
      error_log   /home/appmanager/data/logs/nginx/kibana_error.log;
      location / {
          auth_basic "The Kibana Monitor Center";
          auth_basic_user_file /etc/nginx/ssl/htpasswd;
          proxy_pass   //1.1.1.1:5601;
          proxy_http_version 1.1;
          proxy_set_header Host $host;
          proxy_cache_bypass $http_upgrade;
      }
}

nginx -s reload
