现在主流的Unix系统有两种风格:System V和BSD,他们的区别如下:
Linux作为类Unix,同样也存在这两种风格,其中Centos属于System V,本文主要介绍在Centos下(即System V风格)如何启动和关闭MySQL,同时简单介绍BSD系统的情况。
MySQL启动方式
1)直接调用mysqld。这是最不常见的方式,不推荐使用。
2)运行mysql.server脚本
mysql.server脚本通过调用mysqld_safe启动服务器,该脚本可以通过参数start和stop指定启动还是关闭。
mysql.server脚本在MySQL安装目录下的share/mysql目录中,如果是采用源码安装的MySQL,则可以在support-files目录里找到。如果想使用mysql.server,则必须把它复制到合适的运行级别目录中,如下所示:
[plain] cp mysql.server /etc/init.d/mysqld chmod 755 /etc/init.d/mysqld 如上配置之后,就可以利用以下命令启动和关闭MySQL实例了:[sql] service mysqld start/stop /etc/init.d/mysqld start/stop 使用chkconfig命令配置开机自动启动:[sql] chkconfig --add mysqld chkconfig mysqld on 运行以下命令检查是否正确启用:[plain] [root@data data]# chkconfig --list mysqld mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off MySQL关闭方式[sql] mysqladmin -p -u root shutdown

How to use Docker Desktop? Docker Desktop is a tool for running Docker containers on local machines. The steps to use include: 1. Install Docker Desktop; 2. Start Docker Desktop; 3. Create Docker image (using Dockerfile); 4. Build Docker image (using docker build); 5. Run Docker container (using docker run).

The key differences between CentOS and Ubuntu are: origin (CentOS originates from Red Hat, for enterprises; Ubuntu originates from Debian, for individuals), package management (CentOS uses yum, focusing on stability; Ubuntu uses apt, for high update frequency), support cycle (CentOS provides 10 years of support, Ubuntu provides 5 years of LTS support), community support (CentOS focuses on stability, Ubuntu provides a wide range of tutorials and documents), uses (CentOS is biased towards servers, Ubuntu is suitable for servers and desktops), other differences include installation simplicity (CentOS is thin)

Troubleshooting steps for failed Docker image build: Check Dockerfile syntax and dependency version. Check if the build context contains the required source code and dependencies. View the build log for error details. Use the --target option to build a hierarchical phase to identify failure points. Make sure to use the latest version of Docker engine. Build the image with --t [image-name]:debug mode to debug the problem. Check disk space and make sure it is sufficient. Disable SELinux to prevent interference with the build process. Ask community platforms for help, provide Dockerfiles and build log descriptions for more specific suggestions.

Docker process viewing method: 1. Docker CLI command: docker ps; 2. Systemd CLI command: systemctl status docker; 3. Docker Compose CLI command: docker-compose ps; 4. Process Explorer (Windows); 5. /proc directory (Linux).

VS Code system requirements: Operating system: Windows 10 and above, macOS 10.12 and above, Linux distribution processor: minimum 1.6 GHz, recommended 2.0 GHz and above memory: minimum 512 MB, recommended 4 GB and above storage space: minimum 250 MB, recommended 1 GB and above other requirements: stable network connection, Xorg/Wayland (Linux)

Docker uses Linux kernel features to provide an efficient and isolated application running environment. Its working principle is as follows: 1. The mirror is used as a read-only template, which contains everything you need to run the application; 2. The Union File System (UnionFS) stacks multiple file systems, only storing the differences, saving space and speeding up; 3. The daemon manages the mirrors and containers, and the client uses them for interaction; 4. Namespaces and cgroups implement container isolation and resource limitations; 5. Multiple network modes support container interconnection. Only by understanding these core concepts can you better utilize Docker.

VS Code is the full name Visual Studio Code, which is a free and open source cross-platform code editor and development environment developed by Microsoft. It supports a wide range of programming languages and provides syntax highlighting, code automatic completion, code snippets and smart prompts to improve development efficiency. Through a rich extension ecosystem, users can add extensions to specific needs and languages, such as debuggers, code formatting tools, and Git integrations. VS Code also includes an intuitive debugger that helps quickly find and resolve bugs in your code.
