在linux或unix服务器上安装、使用MySQL的注意事项_MySQL

bitsCN.com 一、怎么样取得最新版本的MySQL?要安装MySQL,首先要当然要取得它的最新版本,虽然大家都知道在FreeBSD的Packages中可以找到MySQL,但是我还是建议大家到网络上去找最新版本的MySQL。我介绍大家到http://www.mysql.org去下载,这里的最新版本是MySQL 3.23 versions 。
二、安装MySQL时候的注意事项?
1、如果您是用MySQL+Apache,使用的又是FreeBSD网路操作系统的话,安装时候你应按注意到FreeBSD的版本问题,在FreeBSD的3.0以下版本来说,MySQL Source内含的MIT-pthread运行是正常的,但在这版本以上,你必须使用native threads,也就是加入一个with-named-thread-libs=-lc_r的选项。
2、如果您在COMPILE过程中出了问题,请先检查你的gcc版本是否在2.81版本以上,gmake版本是否在3.75以上。
3、如果不是版本的问题,那可能是你的内存不足,请使用./configure -- with-low-memory来加入。
4、如果您要重新做你的configure,那么你可以键入rm config.cache和make clean来清除记录。
5、我们一般把MySQL安装在/usr/local目录下,这是缺省值,您也可以按照你的需要设定你所安装的目录。
三、启动和停止MySQL
如果你的机器上从未安装过MySQL的话,在安装MySQL时,最后一个键入的命令是/usr/local/mysql-3.23X/scripts/mysql_install_db
如果你是同时安装多台机器的话,你可以编辑一下这档案,这样一来可以使你方便的设置好每一台的权限。
1、在安装目录/usr/local启动mysql可以使用/usr/local/share/mysql/mysql.server start记得把mysql.server的属性设置成777
2、要停止mysql daemon可以使用/usr/local/bin/mysqladmin shutdown来实现
3、如果你的mysql已经设置了密码,你必须使用mysqladmin -u root -p shutdown来实现
四、用root建一个MYSQL的使用者
你需要先用root登入机器,然后改变目录存取权限chown -R mysql /usr/local/var,接着修改mysql.server 档案,这文件位于/usr/local/share/mysql/下,把mysql_daemon_user=root改成mysql_daemon_user=mysql。
但是在以后新增资料库之后,记得把你的相关档案存取权限改过去:chown -R mysql /usr/local/var/some_new_dbs
如果你希望你的电脑启动时候自动加载mysql,你只要在/et c.local加入一行/usr/local/mysql/share.server startbitsCN.com

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.

The reasons for the installation of VS Code extensions may be: network instability, insufficient permissions, system compatibility issues, VS Code version is too old, antivirus software or firewall interference. By checking network connections, permissions, log files, updating VS Code, disabling security software, and restarting VS Code or computers, you can gradually troubleshoot and resolve issues.
