1.前言

作为一名技术人员，少不了接触数据库，那么当遇到一个旧项目数据库表比较多，怎么快速的导出表结构，形成文档方便后续跟进呢？今天我给大家安利一个好用的工具mysql_markdown。

2.工具官网代码地址

https://github.com/alicfeng/mysql_markdown

它是一款基于 go 语言编写的一个命令行工具，适用于 Linux、Mac、Windows等平台。

3.直接部署（小白推荐方式）

发布包从官网代码直接下载安装

https://github.com/alicfeng/mysql_markdown/releases

下载稳定版本

4.编译部署

有时候我们需要使用工具新特性，可以自行编译此工具，这里也介绍下如何编译最新代码。

4.1部署Go环境

官网下载Go安装包

官网https://golang.google.cn/dl/下载go安装包，选择合适的平台下载安装即可。

Go官网

这里我是macos平台，下载后默认安装在/usr/local/go/目录下。配置环境变量，追加环境变量。$ vim ~/.bash_profileexport GOROOT=/usr/local/go/export GOBIN=$GOROOT/binexport PATH=$GOBIN:$PATH生效环境变量$ source ~/.bash_profile验证是否生效$ which go/usr/local/go/bin/go

4.2编译工具

编译安装（有编译知识的童鞋可以自行编译）

$ git clone https://github.com/alicfeng/mysql_markdown.git$ cd mysql_markdown$ go get "github.com/go-sql-driver/mysql"$ go build -o /usr/local/bin/mysql_markdown mysql_markdown.go$ chmod +x /usr/local/bin/mysql_markdown

5.工具语法

$ ./mysql_markdown_mac --helpUsage: mysql_markdown [options...]--help This help text-h host. default 127.0.0.1-u username. default root-p password. default root-d database. default mysql-P port. default 3306-c charset. default utf8-o output. default current location-t tables. default all table and support ',' separator for filter

是不是和mysql的语法一样，容易上手。

6.工具实战

下面我以导出mysql表为例，这里注意参数选项和参数值要空一格，切记切记！

$ ./mysql_markdown_mac -h 10.10.10.10 -P 33706 -u root -p kkdd123 -d mysql1/31 the columns_priv table is making ...2/31 the db table is making ...3/31 the engine_cost table is making ...4/31 the event table is making ...5/31 the func table is making ...6/31 the general_log table is making ...7/31 the gtid_executed table is making ...8/31 the help_category table is making ...9/31 the help_keyword table is making ...10/31 the help_relation table is making ...11/31 the help_topic table is making ...12/31 the innodb_index_stats table is making ...13/31 the innodb_table_stats table is making ...14/31 the ndb_binlog_index table is making ...15/31 the plugin table is making ...16/31 the proc table is making ...17/31 the procs_priv table is making ...18/31 the proxies_priv table is making ...19/31 the server_cost table is making ...20/31 the servers table is making ...21/31 the slave_master_info table is making ...22/31 the slave_relay_log_info table is making ...23/31 the slave_worker_info table is making ...24/31 the slow_log table is making ...25/31 the tables_priv table is making ...26/31 the time_zone table is making ...27/31 the time_zone_leap_second table is making ...28/31 the time_zone_name table is making ...29/31 the time_zone_transition table is making ...30/31 the time_zone_transition_type table is making ...31/31 the user table is making ...mysql_markdown finished ...

然后你会看到当前目录下会生成一个mysql_20200610_103451.md文件。

Typora打开md文档

7.结束

是不是很简单，生成表结构文档，so easy。你学会了吗？
