我正在尝试通过 exim 使用 proxysql。

我已经进行了必要的配置，但我无法让 exim 从数据库服务器中获取数据。

从 proxysql 到远程数据库服务器的连接工作正常。

mysql -uproxyuser -pPASSWORD -h 127.0.0.1 -P6033 c234 -e "SELECT @@hostname";
mysql: [Warning] Using a password on the command line interface can be insecure.

从 exim 我也看不到错误：

/opt/exim/bin/exim -d+lookup -be '${lookup mysql{servers=127.0.0.1::6033/mydatabase/proxyuser/PASSWORD; SELECT domain FROM eximdomains WHERE active=1 AND domain="pilchita.ferozo.com"}}'

这里是 exim 的调试：https ://pastecode.io/s/a3td0uvw

在 proxysql 日志中我没有看到任何错误，有什么帮助吗？有什么方法可以从proxysql 进行全面调试？

问候，
