To tune MySQL into a Chinese interface, it can be implemented through MySQLWorkbench or command line tools. 1) In MySQLWorkbench, open "Preferences", select the "Appearance" tab, and then select "Chinese(Simplified)" in the "Language" drop-down menu, and restart. 2) When using command line tools, set the operating system locale variables, such as using "exportLANG=zh_CN.UTF-8" on Linux or macOS, and then run the mysql client.

Linux and Windows have their own advantages and disadvantages in CPU and memory usage: 1) Linux uses time slice-based scheduling algorithms to ensure fairness and efficiency; Windows uses priority scheduling, which may cause low-priority processes to wait. 2) Linux manages memory through paging and switching mechanisms to reduce fragmentation; Windows tends to pre-allocate and dynamic adjustment, and efficiency may fluctuate.

Linux's cost of ownership is usually lower than Windows. 1) Linux does not require license fees, saving a lot of costs, while Windows requires purchasing a license. 2) Linux has low hardware requirements and can extend the service life of the device. 3) The Linux community provides free support to reduce maintenance costs. 4) Linux is highly secure and reduces productivity losses. 5) The Linux learning curve is steep, but Windows is easier to use. The choice should be based on specific needs and budget.

The key to installing dual systems in Linux and Windows is partitioning and boot settings. 1. Preparation includes backing up data and compressing existing partitions to make space; 2. Use Ventoy or Rufus to make Linux boot USB disk, recommend Ubuntu; 3. Select "Coexist with other systems" or manually partition during installation (/at least 20GB, /home remaining space, swap optional); 4. Check the installation of third-party drivers to avoid hardware problems; 5. If you do not enter the Grub boot menu after installation, you can use boot-repair to repair the boot or adjust the BIOS startup sequence. As long as the steps are clear and the operation is done properly, the whole process is not complicated.

The key to enabling EPEL repository is to select the correct installation method according to the system version. First, confirm the system type and version, and use the command cat/etc/os-release to obtain information; second, enable EPEL through dnfinstallepel-release on CentOS/RockyLinux, and the 8 and 9 version commands are the same; third, you need to manually download the corresponding version of the .repo file and install it on RHEL; fourth, you can re-import the GPG key when encountering problems. Note that the old version may not be supported, and you can also consider enabling epel-next to obtain the test package. After completing the above steps, use dnfrepolist to verify that the EPEL repository is successfully added.

Linux usually performs better in web server performance, mainly due to its advantages in kernel optimization, resource management and open source ecosystem. 1) After years of optimization of the Linux kernel, mechanisms such as epoll and kqueue make it more efficient in handling high concurrent requests. 2) Linux provides fine-grained resource management tools such as cgroups. 3) The open source community continuously optimizes Linux performance, and many high-performance web servers such as Nginx are developed on Linux. By contrast, Windows performs well when handling ASP.NET applications and provides better development tools and commercial support.

Newbie users should first clarify their usage requirements when choosing a Linux distribution. 1. Choose Ubuntu or LinuxMint for daily use; programming and development are suitable for Manjaro or Fedora; use Lubuntu and other lightweight systems for old devices; recommend CentOSStream or Debian to learn the underlying principles. 2. Stability is preferred for UbuntuLTS or Debian; you can choose Arch or Manjaro to pursue new features. 3. In terms of community support, Ubuntu and LinuxMint are rich in resources, and Arch documents are technically oriented. 4. In terms of installation difficulty, Ubuntu and LinuxMint are relatively simple, and Arch is suitable for those with basic needs. It is recommended to try it first and then decide.
