nginx负载均衡同步上传文件的问题 - SegmentFault
大神们,我现在有个问题,帮我看下:
因为使用nginx均衡负载,由于分发请求到不同服务器,这样如果只想把上传的图片只保存到一台服务器就会出问题。
百度到的方法:
第一种方法是代码里面使用ftp 把文件同步到保存服务器
第二种方法是如果不是保存文件的服务器,使用curl 把文件提交到保存服务器再重新存一次。
第三种方法就是直接使用保存服务器的ip来调接口了。第三种方法我们这边先不考虑。
不知道大神们,遇到这种情况是怎么实现这种需求的

宿主的nginx对于上传的location做特殊处理, 只让一台机器来负责文件上传, 不完美但是有效, 可以作为一段时间的过度方案
搭建一个分布式文件系统, 挂载到所有的服务器上, 处理文件上传后写只写入这个特定目录, nginx中规划一个location指向这个这个目录(例如/data/upload), 缺点就是要多维护一个这个分布式文件系统 (和你的第一种思路有点像, 但分布式文件系统不需要"同步")
使用外部CDN文件上传来解决这个问题, 七牛, 又拍云都可以
1.专门整几台服务器用来存这些静态资源;
2.整出几个盘,弄成网络盘(nfs),专门用来存储这些文件,每个服务器都去挂载这几个盘,和windows的共享文件夹类似;
3.上传成功之后返回一个文件的url,这个url就是文件的地址了;

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

How to configure an Nginx domain name on a cloud server: Create an A record pointing to the public IP address of the cloud server. Add virtual host blocks in the Nginx configuration file, specifying the listening port, domain name, and website root directory. Restart Nginx to apply the changes. Access the domain name test configuration. Other notes: Install the SSL certificate to enable HTTPS, ensure that the firewall allows port 80 traffic, and wait for DNS resolution to take effect.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

How to confirm whether Nginx is started: 1. Use the command line: systemctl status nginx (Linux/Unix), netstat -ano | findstr 80 (Windows); 2. Check whether port 80 is open; 3. Check the Nginx startup message in the system log; 4. Use third-party tools, such as Nagios, Zabbix, and Icinga.

The methods that can query the Nginx version are: use the nginx -v command; view the version directive in the nginx.conf file; open the Nginx error page and view the page title.

Starting an Nginx server requires different steps according to different operating systems: Linux/Unix system: Install the Nginx package (for example, using apt-get or yum). Use systemctl to start an Nginx service (for example, sudo systemctl start nginx). Windows system: Download and install Windows binary files. Start Nginx using the nginx.exe executable (for example, nginx.exe -c conf\nginx.conf). No matter which operating system you use, you can access the server IP
