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.-rc-linux-glibc2.-x86-64bit.tar.gz  -C /usr/local/
ln -s /usr/local/mysql-shell-1.0.-rc-linux-glibc2.-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':
Creating a Session to 'appuser@127.0.0.1:3306'
Enter password:
Classic Session successfully established. No default schema selected.
Welcome to MySQL Shell 1.0.-rc

Type '\help', '\h' or '\?' for help, type '\quit' or '\q' to exit.

Currently in JavaScript mode. Use \sql to switch to SQL mode and execute queries.
mysql-js> 

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': --password=
mysqlx: [Warning] Using a password on the command line interface can be insecure.
Creating a Session to 'appuser@127.0.0.1:3306'
Classic Session successfully established. No default schema selected.

Type '\help', '\h' or '\?' for help, type '\quit' or '\q' to exit.

Currently in JavaScript mode. Use \sql to switch to SQL mode and execute queries.
mysql-js> 

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':/tempdb --password=
mysqlx: [Warning] 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`.

Type '\help', '\h' or '\?' for help, type '\quit' or '\q' to exit.

Currently in JavaScript mode. Use \sql to switch to SQL mode and execute queries.
mysql-js> 

把密码也加到连接字符串中去

mysqlsh 'appuser':''@'127.0.0.1':/tempdb
mysqlx: [Warning] 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`.

Type '\help', '\h' or '\?' for help, type '\quit' or '\q' to exit.

mysql-js> 

4、连接字符串的能用格式

mysqlsh [dbuser[:[dbpassword]]@]host[:port][/schema]

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    |
+------+
|     |
|     |
+------+

在mysqlsh中要用如下的方式执行

mysqlsh  --uri 'appuser':''@'127.0.0.1':
mysqlx: [Warning] 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.

Type '\help', '\h' or '\?' for help, type '\quit' or '\q' to exit.

Currently in JavaScript mode. Use \sql to switch to SQL mode and execute queries.
mysql-js> \use tempdb
Schema `tempdb` accessible through db.
mysql-js> db.student.select()
+---+
| x |
+---+
|  |
|  |
+---+

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。
