We are using a debian in GOogle Compute engine and was allowed port tcp:3306 to connect to mysql but we are unable to conect, any workaround ?
Steps:
Created a Health Checks for my service with the name MySQL;
Pools created a Target for my service named mysql pointing to my region and vm instance;
Rules created a Forwarding Service pointing to my external IP of my VM instance and port you wish to release.
Regards
I changed the configuration file located at /etc/mysql/my.cnf. In there, I changed the bind-address to 0.0.0.0. After following this link, I was able to connect. The Health Checks, Pools and Forwarding rules aren't relevant in this case.

I have a google cloud machine which has an ubuntu Os, I have MySQL database on another server, I opened the remote connection on my SQL server, and I connect to my database from any machine else from my google cloud machine I can not, it taking long time then I have a timeout connection problem.
I think the problem is from firewall rules, so I applied this command to create rule that allow 3306 port
cloud compute firewall-rules create "mysql-remote-access" --allow tcp:3306 --source-tags "mysql-client" --target-tags "mysql-server"
but still, I can not connect to a remote MySQL server
from where can I enable it, thank you
I think your firewall rules is not correct. This one should solve the issue
gcloud compute firewall-rules create "mysql-remote-access" \
--direction=EGRESS --action=ALLOW --rules=tcp:3306 \
--destination-ranges=xxx.xxx.xxx.xxx/32 --target-tags=mysql-client
Short description: You allow the EGRESS traffic on port 3306 to the destination xxx.xxx.xxx.xxx for the traffic coming from the VM with the tag "mysql-client"
By default all the outgoing communication are allowed, but you might have a rule with higher priority that prevents this
Implied allow egress rule. An egress rule whose action is allow, destination is 0.0.0.0/0, and priority is the lowest possible (65535) lets any instance send traffic to any destination, except for traffic blocked by Google Cloud.
It the rule doesn't work, share all your existing firewall rules.
I’ve a question regarding Compute VM and its associated privileges. I have ‘Owner’ privileges at Project level. I created a VM but was not able to assign an external IP address to it. Upon referring to google cloud docs, it appears that I’ll still be able to connect to this VM using VPN or IAP. Upon clicking the SSH link next to the VM, I see that it uses a Cloud-IAP tunnel but the connection fails.
Here is the error message
External IP address was not found; defaulting to using IAP tunneling.
ERROR: (gcloud.compute.start-iap-tunnel) Error while connecting [4003: u'failed to connect to backend'].
ssh_exchange_identification: Connection closed by remote host
ERROR: (gcloud.compute.ssh) [/usr/bin/ssh] exited with return code [255].
How do I go about connecting to this VM?
Appreciate your help with this

https://cloud.google.com/iap/docs/using-tcp-forwarding
Firewall rules that are configured to allow access from Cloud IAP's TCP forwarding netblock, 35.235.240.0/20, on all ports of your machine. This ensures that connections are allowed from Cloud IAP's TCP forwarding IP addresses to the TCP port of the admin service on your resource. Note that you might not need to adjust your firewall rules if the default-allow-ssh and default-allow-rdp default rules are applied to ports used for SSH and RDP.
As probably you already have default-allow-ssh instead of trying:
gcloud compute start-iap-tunnel stage-es-kibana 5601 --local-host-port=localhost:5601
jump to port via extra ssh layer:
gcloud compute ssh stage-es-kibana -- -N -L 5601:localhost:5601
or open Google Firewall between host/port stage-es-kibana:5601 and subnet 35.235.240.0/20.
This is a permissions issue.
You are trying to ssh into your vm thru google's IAP proxy.
You don't have permissions to create the tunnel from your computer to the proxy server.
You need have the role "roles/iap.tunnelResourceAccessor" to ssh to your vm:
It seems that the GCP CE requires to initialize SSH and other services after its RUNNING status.
I used a workaround by adding a sleep (60 sec) command, after starting the VM and before SSH using the IAP tunnel.
In my case I solved or worked around it by omitting the --tunnel-through-iap parameter that is passed to gcloud compute ssh.
try open Google Firewall subnet 35.235.240.0/20
I did set INBOUND PORT RULES in Azure. but still it is not working.
I want to connect this with MySQL workbench and with google VMs it works. If you can please help with this?
Some possible reasons you might consider in this case:
If you can connect to google VM with MySQL Workbench, I suppose the local firewall is open for the destination SQL server ports.
Check the NSG both VM and subnet level.
Check if the SQL server configuration is well, especially the SQL server port, options for connectivity. You can get more references about Connect to a SQL Server Virtual Machine on Azure.
Check if the port 3306 is listening on the Azure VM by using netstat -anpl | grep 3306. If not, you can check if your VM firewall blocks this access.
If the issue still exists, you can add more details about your question.
You need to create a Firewall Rule to allow inbound traffic from the Public IP address where MySQL Workbench is being launched (See Image).
I install mysql manually by sshing the virtual disk of google compute engine . I already create user by following this mysql-adding-user-for-remote-access
and I bind address = 0.0.0.0 then restart mysql service, when I connect remotely using external ip address and the created user it doesn't work. How can I connect I am using HeidiSQL mysql client tool.
Thank you in advance.
By default - the mysql port is closed on google cloud platform. If you want to allow external access you should open that port in the firewall.
To do so you can run (using gcloud):
$ gcloud compute firewall-rules create "mysql-remote-access" --allow tcp:3306 --source-tags "mysql-client" --target-tags "mysql-server"
(Or use the CONSOLE for that: https://console.cloud.google.com/firewalls/add?_ga=1.140859190.569287361.1481048942 )
Note that you will also need to create a user (in mysql) that has access privileges from your own IP, and set this user privileges to allow access to the database you are using).
In my case, I had to also open the firewall within Windows in addition to opening the port using Google VPC networking.
Make sure both boxes (public and private) are checked next to MySQL 57 in the Windows Firewall app.
I've setup a google compute VM, and can access phpmyadmin and the default index page. SSH works when I click the button on the website.
I am having issues remotly connecting to my server instance for any sort of management(ftp or sql)
I followed the firewall section here: https://cloud.google.com/solutions/mysql-remote-access
But I still can't connect.
My firewall is configured:
And I have no idea how to get HTTPS working, But it can be a problem to take care of in the future when I fully switch my site over the compute engine. Since I can't switch my domain or current SSL certificates over yet.
EDIT:
More information:
When I try to connect to SQL using client "Sequel Pro" it returns:
With telnet:
When I try connect to SFTP I get:
Could this be caused by me mistyping the password?
Your firewall settings show that you allowed external traffic to both ports 21 and 3306 for TCP protocol. This is good but not enough.
In order to allow remote connections to MySQL, you will need to grant remote access to your username and your external IP address. Take a look at this case for an example. This is also mentioned in step 6 and step 7 of Configure MySQL server on my-server section of the article you specified:
mysql> GRANT ALL PRIVILEGES ON *.* TO 'TESTUSER'#'<external-ip-my-client>' IDENTIFIED BY '<some-password>';
About the ftp server, the VM instance comes with no ftp service installed, but instead you can use SFTP protocol to connect to it which is more secure than FTP protocol and is highly recommended. Use gcloud compute config-ssh to generate SFTP/SSH key pair. For more information visit Setting up secure FTP on Google Compute Engine artcile.
