Question

我想自动添加mariadb数据库条目，而使用expect脚本我有一些错误。我期待的剧本：

#!/usr/bin/expect 
spawn /usr/bin/mysql -u root -p

expect "Enter password:"
send "123456 \r"

expect "MariaDB [(none)]>"
send "create database zabbixdb character set utf8;\r"

expect "MariaDB [(none)]>"
send "grant all privileges on zabbixdb.* to 'zabbixuser'@'localhost' identified by '123456';\r"

expect "MariaDB [(none)]>"
send "flush privileges;\r"

expect "MariaDB [(none)]>"
send "exit\r"

但它一直失败，错误信息：

spawn /usr/bin/mysql -u root -p
Enter password: invalid command name "(none)"
    while executing
"(none)"
    invoked from within
"expect "MariaDB [(none)]>""
    (file "./mariadb.sh" line 9)

我做错了什么？

Answer 1

从错误消息中看，问题是因为未转义的空方括号[。如果你想匹配文字的开放方括号，那么它应该是，

"MariaDB \\\[(none)]>"

原因是，[对Tcl和Expect都很特殊。除非转义，否则它将被视为命令调用。

将您的代码更改为，

expect "MariaDB \\\[(none)]>"

注意：我们不需要逃离近方括号。

解决了这个问题，我的剧本：

#!/usr/bin/expect

spawn mysql -u root -p123456


expect "MariaDB \\\[(none)]>"
send "create database zabbixdb character set utf8;\r"


expect "MariaDB \\\[(none)]>"
send "grant all privileges on zabbixdb.* to 'zabbixuser'@'localhost' identified by '123456';\r"


expect "MariaDB \\\[(none)]>"
send "flush privileges;\r"


expect "MariaDB \\\[(none)]>"
send "exit;\r"

主要问题是密码验证，请勿使用任何空格“-p123456”
