  一般情况下,我们想要进入MySQL命令模式总是需要按如下交互输入密码确认,才能进入命令行模式:

  zhanhailiang@linux-06bq:~> mysql -u sl -p

  Enter password:

  其实我们完全可以使用expect编写脚本,来通来expect与shell交互通信来实现免密码登录:

  zhanhailiang@linux-06bq:~> cat mysql.sh

  #!/usr/local/bin/expect

  spawn /usr/local/services/mysql/bin/mysql -u sl -p

  expect {

  "assword" { send "slr" }

  }

  interact

  其实这段脚本的意思就是说“执行/usr/local/services/mysql/bin/mysql -u sl -p,等待响应,若匹配assword,则发送sl(即MySQL用户登录密码),回车,,模拟用户手工操作”。

  编写完mysql.sh脚本后,赋予执权限,然后就可以通过执行mysql.sh来免密码进入MySQL命令行模式。

  zhanhailiang@linux-06bq:~> chmod +x mysql.sh

  zhanhailiang@linux-06bq:~> ./mysql.sh

  spawn /usr/local/services/mysql/bin/mysql -u sl -p

  Enter password:
