MySQL 命令行神器：mycli

欢迎关注

今天再推荐一款命令行神器 —— Mycli。
Mycli是一个MySQL命令行客户端工具，具有自动完成和语法突出显示功能。
它是由印度人基于python开发的一个工具，，适合初学者或者对数据库熟悉但命令记不住的人群，能很好地克服记不住命令的困难。

官网：https://www.mycli.net/

安装
建议先安装依赖
$ yum install python-pip python-devel
$ pip install mycli
官方的安装就是先安装python的两个插件后，使用python插件pip来下载安装mycli工具，但很多时候安装都会报错。首先国内的一些yum源可能都不支持安装python-pip工具

安装完python后，你以为直接运行pip install mycli就可以完成安装mycli.

如果遇到以下错误

Cannot uninstall ‘configobj’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
执行一下安装

$ pip install --ignore-installed mycli
一般的已经知道如何安装python包，那么您可以简单地执行：

$ pip install mycli
如果是在macOS上，你可以通过homebrew安装它。

$ brew update && brew install mycli
如果您在安装时遇到问题，请查看官网以获取详细说明。

使用
你只需要一个命令 mycli 就可以启动
