MyCli 简介：

MyCli 是一个 mysql 命令行工具，支持自动补全和语法高亮。也可用于 MariaDB 和 Percona。
参考地址如下：
https://github.com/dbcli/mycli
http://www.cnblogs.com/Jing-420-/p/5883595.html

pgcli 是一个postgresql的命令行工具，支持自动补全和语法高亮
官网地址：
https://www.pgcli.com/
https://github.com/dbcli/pgcli

mycli 使用 prompt_toolkit 编写
当你输入 SQL 关键字，数据库的表格和列时，自动补全。
语法高亮使用 Pygments.
智能补全（默认启用），会提示文本感应的（context-sensitive）补全。
SELECT FROM <tab> 只显示表格名称
SELECT FROM users WHERE <tab> 只显示列名称。
配置文件在第一次启动时，自动创建在 ~/.myclirc
漂亮的打印表格数据。

演示环境：

[[email protected] ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
MySQL5.7.24 二进制安装

安装mycli命令：

首先安装python-pip
使用yum安装python-pip时找不到该软件包，所以我们先安装拓展源。
sudo yum -y install epel-release
然后安装python-pip
sudo yum -y install python-pip python-devel
清除一下cache
sudo yum clean all
现在安装完python-pip了，可以安装mycli了。
sudo pip install mycli

[[email protected] ~]# pip install mycli

[[email protected] ~]#

显示如下表示mycl客户单命令安装成功：

[[email protected] ~]# mycli --help
Usage: mycli [OPTIONS] [DATABASE]
  A MySQL terminal client with auto-completion and syntax highlighting.
  Examples:
    - mycli my_database
    - mycli -u my_user -h my_host.com my_database
    - mycli mysql://[email protected]_host.com:3306/my_database

[[email protected] ~]# cat .my.cnf
[mysql]
user=root
password=‘654321‘
socket=/tmp/mysql.sock

[email protected] [(none)]>select user,host from mysql.user;
+---------------+-----------+
| user | host |
+---------------+-----------+
| mysql.session | localhost |
| mysql.sys | localhost |
| root | localhost |
+---------------+-----------+
6 rows in set (0.01 sec)

[[email protected] ~]# mycli
(1130, u"Host ‘::1‘ is not allowed to connect to this MySQL server")

直接mycli登录报错，应该是没有给数据库授权登录账户

进行登录账户授权如下：

[email protected] [(none)]>grant all on *.* to [email protected]‘127.0.0.1‘ identified by ‘654321‘ with grant option;
Query OK, 0 rows affected, 1 warning (0.02 sec)
