如何在Ubuntu 18.04上安装配置Nginx(安装ELK的先决条件)

本文详细介绍了如何使用sudo权限配置ELK Stack并将其与Nginx服务器集成，包括创建目录、设置文件权限、修改Nginx配置文件等步骤，确保ELK Stack能够正确运行并提供日志分析服务。

$ sudo mkdir -p /var/www/elk/html
$ sudo chown -R $USER:$USER /var/www/elk/html
$ sudo chmod -R 755 /var/www/elk
$ nano /var/www/elk/html/index.html
$ hostname

您将看到以下输出结果

elk

$ sudo nano /etc/nginx/sites-available/elk
$ cat /etc/nginx/nginx.conf

您将看到以下输出结果
