Run the child process using the os/exec package, create the command through exec.Command but not execute it immediately; 2. Run the command with .Output() and catch stdout. If the exit code is non-zero, return exec.ExitError; 3. Use .Start() to start the process without blocking, combine with .StdoutPipe() to stream output in real time; 4. Enter data into the process through .StdinPipe(), and after writing, you need to close the pipeline and call .Wait() to wait for the end; 5. Exec.ExitError must be processed to get the exit code and stderr of the failed command to avoid zombie processes.

In VSCode, you can quickly switch the panel and editing area through shortcut keys. To jump to the left Explorer panel, use Ctrl Shift E (Windows/Linux) or Cmd Shift E (Mac); return to the editing area to use Ctrl ` or Esc or Ctrl 1~9.

When dealing with large tables, MySQL performance and maintainability face challenges, and it is necessary to start from structural design, index optimization, table sub-table strategy, etc. 1. Reasonably design primary keys and indexes: It is recommended to use self-increment integers as primary keys to reduce page splits; use overlay indexes to improve query efficiency; regularly analyze slow query logs and delete invalid indexes. 2. Rational use of partition tables: partition according to time range and other strategies to improve query and maintenance efficiency, but attention should be paid to partitioning and cutting issues. 3. Consider reading and writing separation and library separation: Read and writing separation alleviates the pressure on the main library. The library separation and table separation are suitable for scenarios with a large amount of data. It is recommended to use middleware and evaluate transaction and cross-store query problems. Early planning and continuous optimization are the key.

Check whether the MySQL service is running, use sudosystemctlstatusmysql to confirm and start; 2. Make sure that bind-address is set to 0.0.0.0 to allow remote connections and restart the service; 3. Verify whether the 3306 port is open, check and configure the firewall rules to allow the port; 4. For the "Accessdenied" error, you need to check the user name, password and host name, and then log in to MySQL and query the mysql.user table to confirm permissions.
