php使用pdo连接报错Connection failed SQLSTATE的解决方法_php技巧
本文实例讲述了php pdo_mysql连接报错Connection failed: SQLSTATE[HY000] [2002] No such file or directory问题的解决方法。分享给大家供大家参考。具体方法如下:
错误描述:
Connection failed: SQLSTATE[HY000] [2002] No such file or directory
环境概述:
MacOS
xampp 搭建的开发环境 apache mysql php
xampp 已支持mysql oracle 测试ok,且 phpinfo已上显示支持pdo_mysql pdo_pgsql pdo_sqlite
其中mysql我用的是brew包管理安装到机器里面的,而非xampp自带的mysql
php pdo 连接报错 Connection failed: SQLSTATE[HY000] [2002] No such file or directory
开始以为找不到文件是因为 url rewrite导致的,(因为从nginx切换到apache)结果跟踪程序发现是 new pdo 报错
经过搜索一些资料研究发现:
这个是php.ini配置文件中pdo_mysql.default_socket指定的mysql.sock路径不对
我的mysql.sock文件在 /private/tmp/mysql.sock
所以要设置:
如果不知道自己的mysql.sock在哪里可以搜索(因为编译安装,和yum、apt-get、或者brew等包管理工具安装的位置不一样)
sudo find / -name 'mysql.sock'
下面是官方给出bug修复
1. Open up php.ini (mine was in /private/etc/)
2. locate this line: pdo_mysql.default_socket=/var/mysql/mysql.sock
3. Change the line to: pdo_mysql.default_socket=/tmp/mysql.sock
4. Restart apache
1、我这里需要补充下,如果是新系统或者刚玩php的同志,在Mac的系统中php.ini 文件不存在。
2、需要在/private/etc/目录下cp php.ini.default
php.ini ,然后再做修改下
3、但是如果使用的xampp mysql作为数据库,那么就不需要使用官方的step2,直接写下面方式就可以了。
解决方法三:
把以下三个原来空白的值都设置为:
mysql.default_socket = /tmp/mysql.sock
pdo_mysql.default_socket= /tmp/mysql.sock
mysqli.default_socket =/tmp/mysql.sock
都修改了
修改完成后使用
问题搞定!
希望本文所述对大家的PHP程序设计有所帮助。

In PHP, the final keyword is used to prevent classes from being inherited and methods being overwritten. 1) When marking the class as final, the class cannot be inherited. 2) When marking the method as final, the method cannot be rewritten by the subclass. Using final keywords ensures the stability and security of your code.

The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.

The default style of the Bootstrap list can be removed with CSS override. Use more specific CSS rules and selectors, follow the "proximity principle" and "weight principle", overriding the Bootstrap default style. To avoid style conflicts, more targeted selectors can be used. If the override is unsuccessful, adjust the weight of the custom CSS. At the same time, pay attention to performance optimization, avoid overuse of !important, and write concise and efficient CSS code.

Export default in Vue reveals: Default export, import the entire module at one time, without specifying a name. Components are converted into modules at compile time, and available modules are packaged through the build tool. It can be combined with named exports and export other content, such as constants or functions. Frequently asked questions include circular dependencies, path errors, and build errors, requiring careful examination of the code and import statements. Best practices include code segmentation, readability, and component reuse.

The following steps can be used to resolve the problem that Navicat cannot connect to the database: Check the server connection, make sure the server is running, address and port correctly, and the firewall allows connections. Verify the login information and confirm that the user name, password and permissions are correct. Check network connections and troubleshoot network problems such as router or firewall failures. Disable SSL connections, which may not be supported by some servers. Check the database version to make sure the Navicat version is compatible with the target database. Adjust the connection timeout, and for remote or slower connections, increase the connection timeout timeout. Other workarounds, if the above steps are not working, you can try restarting the software, using a different connection driver, or consulting the database administrator or official Navicat support.

The solution to MySQL installation error is: 1. Carefully check the system environment to ensure that the MySQL dependency library requirements are met. Different operating systems and version requirements are different; 2. Carefully read the error message and take corresponding measures according to prompts (such as missing library files or insufficient permissions), such as installing dependencies or using sudo commands; 3. If necessary, try to install the source code and carefully check the compilation log, but this requires a certain amount of Linux knowledge and experience. The key to ultimately solving the problem is to carefully check the system environment and error information, and refer to the official documents.

There are many reasons why MySQL startup fails, and it can be diagnosed by checking the error log. Common causes include port conflicts (check port occupancy and modify configuration), permission issues (check service running user permissions), configuration file errors (check parameter settings), data directory corruption (restore data or rebuild table space), InnoDB table space issues (check ibdata1 files), plug-in loading failure (check error log). When solving problems, you should analyze them based on the error log, find the root cause of the problem, and develop the habit of backing up data regularly to prevent and solve problems.

Solutions to the garbled code of Bootstrap Table when using AJAX to obtain data from the server: 1. Set the correct character encoding of the server-side code (such as UTF-8). 2. Set the request header in the AJAX request and specify the accepted character encoding (Accept-Charset). 3. Use the "unescape" converter of the Bootstrap Table to decode the escaped HTML entity into original characters.
