运维 - nginx + php 上传图片报warn
网站是nginx+php,有个接口是接受用户上传的图片,当接口并发量大的时候会报nginx warn
<code>a client request body is buffered to a temporary file /var/cache/nginx/client_temp/***** </code>
查了一下资料,应该是客户端请求内容大于缓冲区,请求内容被写入临时文件 一般用户上传的图片都有1M左右,是否可以
<code>client_body_buffer_size 1024k </code>
疑问:这样是否就是将请求保存在内存中?那么请求量大的时候会不会因为内存不足造成更大的问题
最近服务器负载会飙高,估计也和这个接口有关系,上传图片比较慢导致大量php进程在处理,是否有其它替代方案?

如果你设定了最大的buffersize,那么当这个maxbuffer_size小于可以使用的内存大小时,是不会报内存不足的,这点可以不用担心。如果要坚持用php做这个的话,我个人觉得只能加强些硬件性能了,否则可以换一种异步io的方式做做看(nodejs),但不见得一定有效,也不知道会不会有其他方面的问题。
这本身就不是个问题。我nginx设置的上传大小是100wGB。我认为就不应该设置这个限制。然后说回问题本身,有这么多用户你还愣用一个小水管!!?!?!这本身就不科学啊!!那腾讯网银新浪神马的岂不是都能一台服务器搞定所有事了= =

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.

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 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.

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.

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.

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.

Steps to create a Docker image: Write a Dockerfile that contains the build instructions. Build the image in the terminal, using the docker build command. Tag the image and assign names and tags using the docker tag command.
