命令行提示“20752 -bash: $: command not found [1] Exit 127”,这可能是因为$符号被当做了命令来执行,而不是变量的引用。建议检查命令语法和变量使用是否正确。
对于命令“sudo mysqld_safe --init-file=/path/to/mysql-init”,它是用于启动MySQL数据库并且执行指定的初始化脚本。其中“/path/to/mysql-init”是初始化脚本的路径,需要根据实际情况进行替换。该命令需要使用root权限,因此使用sudo命令来执行。

This error message indicates that the command prompt is trying to execute a command that begins with a "$" symbol, which is not a valid command. It is possible that the "$" symbol was accidentally included in the command when it was entered.
The second part of the error message indicates that the command "sudo mysqld_safe --init-file=/path/to/mysql-init" was executed but exited with an error code of 127. This could be due to a variety of reasons, such as a missing or incorrect file path, insufficient permissions, or an issue with the MySQL server itself.
To resolve this issue, try removing the "$" symbol from the beginning of the command, ensuring that the file path specified in the "--init-file" option is correct, and checking that the user executing the command has sufficient permissions to run it. Additionally, you may want to check the MySQL server logs for any error messages that could provide more information about the issue.

如果你在执行 "sudo mysql -u root -p" 命令时遇到 "-bash: :mysql: command not found" 错误,这可能意味着你的系统没有正确安装或者配置了MariaDB。
你可以尝试以下步骤来解决这个问题:
1. 确保你已经正确安装了MariaDB。你可以通过运行以下命令来检查:
```
sudo apt-get install mariadb-server
```
这将安装MariaDB服务器。
2. 如果已经安装了MariaDB,但是仍然遇到问题,可能是因为MariaDB的可执行文件路径没有被正确添加到系统的环境变量中。
你可以尝试手动指定可执行文件的路径来运行MariaDB。在终端中输入以下命令:
```
sudo /usr/bin/mysql -u root -p
```
请注意,上述路径 `/usr/bin/mysql` 可能会因为不同的系统而有所不同。你可以使用 `which mysql` 命令来查找正确的路径。
希望这些步骤能够帮助您解决问题并成功启动MariaDB。
