mysql-shell的安装和使用
mysql-shell是一个高级的mysql命令行工具、它直接两种模式(交互式&批处理式)三种语言(javascript\python\sql）1、下载地址
https://dev.mysql.com/downloads/shell/
2、安装 安装方法就比较简单了，下载一个linux-general版本的解压就行
mysql-shell-1.0.8-rc-linux-glibc2.12-x86-64bit.tar.gz-C /usr/local/
ln -s /usr/local/mysql-shell-1.0.8-rc-linux-glibc2.12-x86-64bit /usr/local/mysqlsh
export PATH=/usr/local/mysqlsh/bin/:$PATH
3、通过mysql-shell连接到mysql-server
mysqlsh 'appuser'@'127.0.0.1':3306
Creating a Session to
'appuser@127.0.0.1:3306'
Enter password:
Classic Session successfully established. No default schema selected.

mysql

第每连接都要输入密码、就是不喜欢、好在可以直接指定它
mysqlsh 'appuser'@'127.0.0.1':3306 --password=123456
mysqlx: Using a password on the command line interface can be insecure.

除了这个之处还可以在连接字符串中指定数据库的名字，类似于use dbname；的效果
mysqlsh 'appuser'@'127.0.0.1':3306/tempdb --password=123456
mysqlx: Using a password on the command line interface can be insecure.
Creating a Session to
'appuser@127.0.0.1:3306/tempdb'
Classic Session successfully established. Default schema set to `tempdb`.

把密码也加到连接字符串中去
mysqlsh 'appuser':'123456'@'127.0.0.1':3306/tempdb
mysqlx: Using a password on the command line interface can be insecure.
Creating a Session to
'appuser@127.0.0.1:3306/tempdb'

4、连接字符串的能用格式
mysqlsh ]@]host[:port]
5、应用举例
假设我要执行如下的select 语句、在mysqlsh中我要怎么做呢？
mysql -uroot -e"select * from tempdb.student" -vt
--------------
select * from tempdb.student
--------------
+------+
| x |
+------+
| 1 |
| 2 |
+------+
在mysqlsh中要用如下的方式执行
mysqlsh--uri 'appuser':'123456'@'127.0.0.1':33060
mysqlx: Using a password on the command line interface can be insecure.
Creating a Session to
'appuser@127.0.0.1:33060'
Node Session successfully established. No default schema selected.

mysql

Schema `tempdb` accessible through db.
mysql

| 1 |
| 2 |
+---+
总结：
就目前的情况来说mysqlsh是一个数据库初学者的工具(会javascript,python不太精通SQL)，像资深的DBA应该还是用不太着的。
我个人感觉mysqlsh对一个dba来说并没有mysql这个客户端工具来的方便。
