vscode调试mysql5.7.37教程_mysql 源码调试 vscode

前一篇用的是launch，这一篇更改为attach。

1.启动数据库

/usr/local/mysql/support-files/mysql.server start
1

2.进入数据库

mysql -uroot -p
1

我在/etc/my.cnf 加了skip-grant tables
免密登录（问也是空密码）

顺便查了一下版本

3.改了配置文件

    // Hover to view descriptions of existing attributes.

    "version": "0.2.0",
    "configurations": [
        {
            "name": "openGauss-debug",
            "type": "cppdbg",
            "request": "attach",
            "program": "/usr/local/mysql/bin/mysqld",
            "args": ["--user=mysql --datadir=/usr/local/mysql/data"],
            "processId": "${command:pickProcess}",
            "MIMode": "gdb",
            "setupCommands": [
                {

                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                },
                {
                    "description":  "Set Disassembly Flavor to Intel",
                    "text": "-gdb-set disassembly-flavor intel",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

4.调试

以时间函数Item_time_literal（）为例：
先打好断点，我打在了1041行，通过命令查看进程号

ps aux | grep mysql
1

打好断点就run->start debugging
选择attach 12430

• 终端进入数据库输入查询语句敲enter
  
  与此同时，vscode图形化界面就会开始调试！
