bitsCN.comubuntu下启动mysql服务出现The server quit without..问题
这个错误是如何产生的呢?
启动mysql 为什么会报 The server quit without updating PID file(....pid )
产生的原因有几种,
1:配置文件出现错误my.cnf
2:/usr/local/mysql/data 文件夹 的权限问题
3:进程已存在 mysql 的服务
首先 说说楼主的遭遇, 由于
配置 mysql 默认编码格式的时候出现配置错误,导致启动mysql (后来才想起来 我改过配置文件了)
The server quit without updating PID file(updat file .....pid )
悲催的折腾到2点多,google 查各种资料..于是便有了上面几个总结
问题1 的解决:
由于我当时脑抽了估计,居然改/usr/local/mysql/my.cnf 配置文件,导致后来才发现这里改动过了,
但是mysql 启动的时候,我觉得应该是这样进行查找my.cnf 的
首先 /etc/my.cnf 是否存在
1if( true):2 读取/etc/my.cnf3else:4
读取/usr/local/mysql/my.cnf | /usr/local/mysql/my.cnf~
检查发现 my.cnf 没问题,于是问题1 忽略( 结果就是折腾到2点,忽略了/usr/local/mysql/my.cnf 的检查 )
问题2:
usr/local/mysql/data 权限的问题, 看当前登入用户是否具有写的权限. 这里要搞清楚 linux 群组与文件拥有者 权限的关系(不清楚? 鸟哥私房菜.)
问题3:
查看进程是否有 mysql 服务的进程,有的话 kill 掉
命令:
ps aux|grep mysql
若存在, kill -9 相对应的 id(例如3871)
三个问题,解决.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The process of starting MySQL in Docker consists of the following steps: Pull the MySQL image to create and start the container, set the root user password, and map the port verification connection Create the database and the user grants all permissions to the database

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

The key to installing MySQL elegantly is to add the official MySQL repository. The specific steps are as follows: Download the MySQL official GPG key to prevent phishing attacks. Add MySQL repository file: rpm -Uvh https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm Update yum repository cache: yum update installation MySQL: yum install mysql-server startup MySQL service: systemctl start mysqld set up booting
