HomeBackend DevelopmentPHP Tutorialphp 远程连接Oracle 报错 oci_connect(): ORA-12541: TNS:no listener

情况如下:

  1. Oracle和php不在同一台机器上,在Oracle所在的机器上可以访问Oracle。

  2. 但是通过php远程连接时,报错oci_connect(): ORA-12541: TNS:no listener。

  3. Oracle所在机器的listener已经打开了的。

如何解决php远程连接,谢谢!

各种方法都试过了,最后把oracle卸载了重新安装后,一切正常...

在oracle的服务器上,用下面的命令,查看oracle的监听服务是否运行正常

<code>su - oracle
lsnrctl status</code>

如果监听服务正常的话,应该输出下面类似的结果, XXX是serive和instance的名称
Service "XXX" has 1 instance(s).
Instance "XXX", status READY, has 1 handler(s) for this service...
The command completed successfully

首先确认一点PHP报错no listener那就肯定是no listener这一点不用质疑。

1.远程连接Oracle是否可以连接(Oracle是否允许远程访问)
2.PHP所在服务器是否能连通Oracle所在服务器。

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
