我尝试启动xampp mysql服务，但我失败了。我已经在Windows服务面板中禁用了mysql服务，并在my.ini文件中将端口3306更改为3309。
# The following options will be passed to all MySQL clients
[client]
# password = your_password
port = 3309 // change here
socket = "C:/xampp/mysql/mysql.sock"
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
port= 3309 // change here
socket = "C:/xampp/mysql/mysql.sock"
basedir = "C:/xampp/mysql"
tmpdir = "C:/xampp/tmp"
datadir = "C:/xampp/mysql/data"
pid_file = "mysql.pid"
# enable-named-pipe
key_buffer = 16M
max_allowed_packet = 1M
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
log_error = "mysql_error.log"
然而，仍有人说
5:56:19 PM [mysql] Problem detected!
5:56:19 PM [mysql] Port 3306 in use by "C:\mysql_community_server\bin\mysqld MySQL"!
5:56:19 PM [mysql] MySQL WILL NOT start without the configured ports free!
5:56:19 PM [mysql] You need to uninstall/disable/reconfigure the blocking application
5:56:19 PM [mysql] or reconfigure MySQL and the Control Panel to listen on a different port

问题：
为什么我更改为端口3309并且仍然连接到端口3306？
我已经禁用了其他mysql服务，所以即使它是3306，它仍然可以连接
