1、下载mysql-8.0.33 源码包（包含boost库）

2、解压文件

 tar -xvf mysql-boost-8.0.33.tar.gz

3、在解压后的mysql-8.0.33文件夹创建vscode的配置文件夹.vscode,并配置settings.json和launch.json

#settings.json
{
    "cmake.buildBeforeRun": true,
    "cmake.buildDirectory": "/Users/xxx/cpp/src_project/mysql-8.0.33/build",
    "cmake.configureSettings": {
        "WITH_DEBUG": "1",
        "CMAKE_INSTALL_PREFIX": "/Users/xxx/cpp/src_project/cmake-build-debug/bin",
        "MYSQL_DATADIR": "/Users/xxx/cpp/src_project/cmake-build-debug/data/mysql_data/",
        "SYSCONFDIR": "/Users/xxx/cpp/src_project/cmake-build-debug/etc/my33.cnf",
        "MYSQL_TCP_PORT": "3306",
        "WITH_BOOST": "/Users/xxx/cpp/src_project/mysql-8.0.33/boost/boost_1_77_0",
        "DOWNLOAD_BOOST": "1",
        "DOWNLOAD_BOOST_TIMEOUT": "600"
    }
}

#launch.json
{
    // 使用 IntelliSense 了解相关属性。 
    // 悬停以查看现有属性的描述。
    // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lldb",
            "request": "launch",
            "name": "Debug mysqld",
            "program": "/Users/xxx/cpp/src_project/cmake-build-debug/bin/bin/mysqld",
            "args": [
                "--defaults-file=/Users/xxx/cpp/src_project/cmake-build-debug/etc/my33.cnf"
            ],
        },
        {
            "type": "lldb",
            "request": "launch",
            "name": "Debug mysql",
            "program": "/Users/xxx/cpp/src_project/cmake-build-debug/bin/bin/mysql",
            "args": [
                "-uroot",
                "-P3307",
                "-h127.0.0.1"
            ],
        }
    ]
}

4、安装vscode相关插件

5、新建build和数据配置目录（本文以我的环境为例，xxx是我的用户名，根据自己电脑环境配置）

mkdir -p /Users/xxx/cpp/src_project/cmake-build-debug
cd /Users/xxx/cpp/src_project/cmake-build-debug/
mkdir -p {bin,data,etc}
mkdir -p /data/{mysql_data,mysql_log, mysql_slow}

6、设置mysql配置文件，放在/etc/目录下

#cat my33.cnf
[client]
port            = 3306
socket          = /tmp/mysql.sock
default-character-set=utf8mb4

[mysqld]
# generic configuration options

key_buffer_size = 64M

7、编译
【vscode菜单栏】->【view】->【command Palett...】-> 【CMake build target】->【mysqld】

8、到终端文件目录下

make install 

9、初始化数据 在编译完成的二进制目录下

./mysqld --defaults-file=/Users/xxx/cpp/src_project/cmake-build-debug/etc/my33.cnf --initialize-insecure

10、启动调试
