Nginx 结合Python Ldap认证用于Kibana权限登陆

参考及依赖

https://github.com/nginxinc/nginx-ldap-auth
http://nginx.org/
nginx-1.14.2
http_auth_request_module
nginx-ldap-auth
python2.7
python-ldap

Nginx支持ldap

  1. 部署nginx,注意需要http_auth_request_module支持
wget http://nginx.org/download/nginx-1.14.2.tar.gz
tar zxvf nginx-1.14.2.tar.gz
cd nginx-1.14.2
./configure --with-http_auth_request_module
make
make install
/usr/local/nginx/sbin/nginx
  1. 配置nginx,注意ldap配置

Python Ldap认证

wget https://github.com/nginxinc/nginx-ldap-auth/archive/0.0.4.tar.gz
tar zxvf 0.0.4.tar.gz
python nginx-ldap-auth-daemon.py &

后端登陆跳转页面

默认页面只能测试,这里需要大概改下才能使用
vim backend-sample-app.py
python backend-sample-app.py &
backend-sample-app.py其中html=“““修改后如下
