2、打印数据库连接信息，发现主机地址为内网IP，容器无法访问
stdClass Object
(
[tmp] => Array
(
[datasource] => Database/Mysql
[persistent] =>
[host] => 192.168.150.23
[login] => contenttest
[password] => xxxxxxxx
[database] => creditnew_2de4ad2e76a6d76ee2368b1c93cec41a
[port] => 3306
[prefix] => operation_
[encoding] => utf8
)
)
3、调整为外网IP，打印数据库连接信息，容器可以正常访问。如图2
stdClass Object
(
[tmp] => Array
(
[datasource] => Database/Mysql
[persistent] =>
[host] => xxxxxxxxxxx.bj.tencentcdb.com
[login] => contenttest
[password] => xxxxxxxx
[database] => creditnew_2de4ad2e76a6d76ee2368b1c93cec41a
