Not very sure I understood the problem in detail.Please let me explain step by step.
I setup two web servers and one at my PC and another one at AWS EC2 instance.
I installed phpmyadmin for localhost. I can access my phpmyadmin at localhost and setup database and web application at localhost.
When I tried to install phpmyadmin at AWS EC2 instance, installation is fine.
But access to the phpmyadmin has problem and always have 403 Forbidden error.
That error is always because of right ip address issue at /etc/httpd/conf.d/phpMyAdmin.conf file.
The problem is there. If I set the Public ip for that particular EC2 instance, I have 403 Forbidden error.If I changed to default ip as 127.0.0.1, then I can access the phpmyadmin installed at my localhost not at EC2 instance. So I am curious about
(1)Why I can't access the phpmyadmin installed at EC2 instance with Public IP address of that instance.
(2)Why there is a connection or link or association between the two phpmyadmin installed at my localhost and the EC2 instance?
Thanks
Let me see if I understood your question well.
127.0.0.1 is localhost address, if you try to access that Ip from your computer you will be accessing your own pc and everything that is installed in there: mysql, phpmyadmin, etc
For the AWS server, to access phpmyadmin from outside make sure that the security group assigned to your EC2 server has port 80 enabled from your public IP address at the inbound tab

I am unable to access an AWS server on various software -- Microsoft Remote Desktop, MySQLWorkbench and DBeaver. The credentials are correct and the same as those of my teammates and they are able to access the server. It resolves the hostname to be the IP address and not the host address, which is strange. In the dialog box attached, it should say that Access is denied to admin# but it says admin instead.
I have tried uninstalling and installing MySQLWorkbench multiple times. I uninstalled and installed the mysql library. I have tried changing the my.cnf files but that doesn't help either. I have a suspicion that it may be something on the server-side (AWS). I looked at the AWS console and it allows access to all IP addresses. I have tried a lot of things and still face the issue of the hostname being resolved to the local IP.
Can you please help me out?
enter image description here
I have the following topology.
One Ubuntu 16.04. Instance on the Amazon AWS where my global MySQL Server is running. I want to use this Server as a Slave (Multi-Source Replication) for many local Master (Windows Machines MySQL Server).
For Testing Reasons I`ve Managed to make this running on one local Machine (with three different MySQL Server Running).
But now I want to make this Replication work on the mentioned global Server with the local ones. But it fails on the attempt to connect from the EC2 ubuntu Instance to the local Windows MySQL Server.
When I try to connect from my EC2 Instance to the local Computer with MySQL running on Port 3307 it keep saying:
ERROR 2003 (HY000): Can't connect to MySQL server on (113)
The strange Part is, that I can PING the Local Computer but not telnet it.
Telnet just says:
telnet: Unable to connect to remote host: No route to host
I can access the Global (EC2 / Ubuntu MySQL Server) from the local Machine but not the other way around.
I`ve already made a new Rule for this Port on the Windows Firewall Settings.
But the Port 3307 on the IPv4 Address seems to be still Closed.
I have no clue what I am missing to get a Connection from the EC2 Instance to my local Computer via TCP.
Do I have to open the Port Specific on the Router?
I hope for your help.
Best Regards.
It seems like your local computer is not visible, as your incoming ports to your local pc are closed. It may be a problem with your router, or your internet service provider, which is not allowing you to open ports(the most common one).
The possible solutions are:
1.) If your ports are not open due to the router
Try forwarding required ports to your pc.
Try Switching off your NAT firewall that may be blocking ports.
Try switching off your windows or antivirus firewall if any.
2.) If your ports are blocked by your Internet service provider.
Try getting help from ISP
Switch to a static IP connection if on dynamic.
Use a VPN service that provides an unblocked port service to all IPs.(This one solved my problem when I was struck in this situation.)
Apologies for the bad english, i'm french. :D
I've been looking for an answer since approximatively 4 days, and I don't know how to fix my issue.
So:
I want to virtualize two servers using virtualBox on Windows7 and i want them all on the same local network.
My VMs are running on Ubuntu 16.04
On the first VM I installed a lamp web server with MySQL 5.7 and i add phpmyadmin.
On the second VM I installed Jira standalone
--> I need to connect to my Database from my Jira server
So I used the Bridge adapter on each machine:
network configuration
network configuration
Ip adresses are attributed with the DHCP protocol.
The SQL machine ip is 192.168.6.80
The Jira machine ip is 192.168.6.101
The Host machine ip is 192.168.6.87
I'm able to ping each machine so there is no problem.
SQL server
When I start the machine everything seems to work, i can access from my SQL server:
localhost : home page of apache 2 saying "It Works"
localhost:5671 :
[���
5.7.18-0ubuntu0.16.04.1� ���UKBeM�ÿ÷�ÿ����������T(DGKg1hwd=�mysql_native_password���ÿ„Got
packets out of order
localhost/phpmyadmin : the index page where I can connect perfectly with root.
Host Machine (Windows)
192.168.6.80 : home page of apache 2 saying "It Works"
192.168.6.80:5671 :
[���
5.7.18-0ubuntu0.16.04.1� ���UKBeM�ÿ÷�ÿ����������T(DGKg1hwd=�mysql_native_password���ÿ„Got
packets out of order
192.168.6.80/phpmyadmin : the index page where I can connect perfectly with root.
Jira server
Here when i start the machine it works during approximatively 2-3 minutes,
I'am able to connect via:
mysql -u root -p -h 192.168.6.80 -P 5671
I am perfectly connected and i can also access to all the other adresses.
And then it stop working on this machine only.
Unable to connect
Firefox can’t establish a connection to the server at 192.168.6.80.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
And when i re-try to connect via mysql on terminal I get the Error 2003 (HYOOO)
This happen only when i use the connection of my work, at home it works perfectly without stopping!!
I have few leads:
problems of proxy authentication
problems of firewall configuration
i am in a private network with a domain name called something.eu
And when i launch firefox the proxy shows up automatically:
and-etc-ha.something.eu:9090
So i'm invited to enter my id and password.
My id is : luc.myName#something.eu
After that i'm connected to internet with firefox but not in terminal when i want to use apt.
I search on the web and i found this:
export http_proxy="http://Username:password#proxyip:port/"
and
export http_proxy="http://Domain\user:pasword#proxyip:port/"
So I tried different ways and i was able to download with apt. But the internet connexion with firefox was unstable. But if I use firefox on my host machine the connexion is perfect.
I also tried with settings -> network -> network proxy -> method manual
http: and-etc-ha.something.eu port: 9090
I don't know if I was understandable, tell me!^^
If you have any ideas to help me to solve this problem let me know.
Bye!
I found the cause: In fact there was a ip conflict inside the LAN because the DHCP was giving in-use ip address.
I decide to use the NAT connection with Port Forwarding on VirtualBox.
With that configuration I'm able to access my VMs on my LAN using the host ip address followed by the port of my choice.
I have a MySql Server 5.7 running as service on one computer of a LAN.
My application is installed and running fine on the same computer. I have 'Shared with everyone' set for the directory where my application is located. In the same directory I have put the libmysql.dll and the FDConnectionDefs.ini files.
My application is running fine on that computer. On the other computers on the LAN I created a link to the directory where my application is shared. When I try to run my application from these LAN systems they produce the error message
[FireDac][Phys][mySql] can't connect to mySql server 127.0.0.1 on port 3306... (10061).
All machines are running Windows 10 on 64 bit processors.
Here what i've tried to resolve the problem:
make sure that the user, password and host (%) are the same in mySql Profile and FDConnectionDefs.ini.
I've tried with different users even with root, i've tried to change host (%) to put the IP address of the computer trying to connect in the mySql profile.
I make sure that i have permissions to run my application and mySql and that the port 3306 is open in the Firewall/Kaspersky on each computer of the LAN. But always the same error message.
127.0.0.1 is a special IP address - the "loopback" address that is typically resolved for localhost on most systems. It is a private internal IP address that a computer can use to refer to itself. It has no meaning to other systems on a LAN since every computer will recognize 127.0.0.1 as meaning itself.
This means that when you are running the application on a remote system it will be trying to connect to a MySQL server running locally rather than on a server elsewhere.
You'll need to configure your FireDac components to connect to the actual LAN IP address that belongs to the system hosting the MySQL server. You will probably also need to make sure that your MySQL users are set up to authenticate from an IP other than localhost.
Is it possible to do the following?:
I have a local Mac running OS X Lion with a MySQL Server installed which runs different processes regularly and stores data into a local DB.
On the other hand I have an Amazon EC2 instance.
What I would like to do is to use the Amazon instance to perform certain cronjobs (using its own resources) but connecting to the data that is on my localhost (my computer) and performing basic SQL actions like updating the data, inserting, etc.
I don't know if this helps, but I have a static IP. Is there any way I can "open" my IP so the Amazon instance can recognize my home computer as a valid MySQL server?
Thanks for your help, any tip in the right direction will be much appreciated.
If your EC2 instance is connecting to your local db you'll need a static IP locally. Well not need... but if you don't have it anytime you reset your router or loose power etc your ip will change. You can look into Dynamic DNS as well for your local instance.
Your ISP will not block your port on your local instance. This would be a firewall inside your network that is preventing you from connecting to mysql or a configuration with mysql itself. Users can only connect to mysql from certain IP addresses.
You would have to open up the mysql port on your firewall if you are using one, have the mysql client installed on your EC2 instance, and make sure that the user that had proper grantable permissions.
That said why not run cron locally on the mac?
If you can login to your server via SSH then there's no need to open any other port and no static IP is required. You can use SSH port forwarding instead. From your local machine run:
ssh -C -R 5555:127.0.0.1:3306 <your-server-host>
Now you should be able to connect to your Mac's database running on localhost:3306 from the remote server at localhost:5555.
