nginx - php-fpm 一直是ESTABLISHED
这两天服务器上的php-fpm 一直很奇怪的被一个外部ip访问到 我的php-fpm配置里 做了ip限制 listen.allowed_clients = 127.0.0.1 但是他还是能连进来 而且不是通过9000端口进来的 整个进程一直被占用处于ESTABLISHED状态 怎么回事 是php-fpm有漏洞么 该怎么查杀 ？为什么php-fpm本来监听的9000端口 却通过其他端口连出去了
正常的连接 是下面截图

web server和fastcgi之间是通过网络连接的啊
一段fastcgi listen 9000，另一端难道不要开端口吗？
因为nginx和php之间是长连接，一旦连接建立成功，就不需要再关闭了，然后两者就可以一直愉快的通信了啊。如果用完一次，就关闭一次，会凭空产生不必要的重连的时延。反正这个连接就只有nginx和php使用，不用担心连接数被耗尽;传统的http协议之所以要做成短连接，是由于web服务是在公网上使用，一个浏览器访问当前网站建立的socket连接如果长时间不释放，然后每个访问的浏览器都学他不释放，服务器连接数就会被耗尽。综上所述，就是长短连接之间的区别和用途了。
我现在已经知道是什么了 那是php和memcache建立的长连接 和nginx没关系 请看清截图和问题 链接是从php出去连外部的 不是外部来连php谢谢

PHP: Handling Databases and Server-Side Logic
Apr 15, 2025 am 12:15 AM
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.
