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 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 have followed all instructions give across google but somehow i am unable to get access from my desktop to a remote mysql database installed on Google Compute Engine.
I have done the following
a) create user and grant him permissions to get access remotely
b) allow the port in firewall
c) comment out bind-address
but still i get the error
when i try to connect from my remote windows client.
where i am i missing a required step??? Please help...
Ensure that you have allowed TCP traffic from your location to VM in question to port 3306 on a project level in Cloud Console or using CLI:
gcloud compute firewall-rules list
More about setting up firewalls in official documentation:
https://cloud.google.com/compute/docs/vpc/firewalls
As far as I can tell, google doesn't allow remote connections to a mysql DB on cloud engine. Only between VMs, but now with an external client.
It is only allowed if you are using a dedicated Cloud SQL instance
See the first paragraph on this article (I'd be happy to be proven wrong though):
https://cloud.google.com/solutions/mysql-remote-access
Near the bottom they indicate non-compute engine access is out of scope for the article, but tells you to basically do the same stuff and set the google firewall for external access and the db user to access from outside.
I'm trying to connect my local MySQL to a test 2nd generation MySQL instance on Google SQL platform using the following command on my windows laptop.
mysql --host=130.211.xx.xx --port=3306 --user=root --password
I double checked my IP address with whatismyIPaddress.
I can connect via Google Cloud Shell on the Google Platform itself and also ping the IP address from the local cmd prompt.
As a troubleshooting step I have disabled the local firewalls on my laptop and granted full access to 0.0.0.0/0 to allow all connections on the google platform console.
still no joy from either a cmd line connection on windows or using a putty client, can anyone give me any further pointers on the missing step?
Cheers..
If you are behind a NAT your IP might change which prevents you from accessing the Cloud SQL instance. I would recommend setting up access using SSL certificate. More information about the setup can be found in this Help Center article.
You may need to allow remote connections to your remote database in the server and database configuration. These kinds of connections are typically disabled by default.
I can't connect Google Cloud SQL from GCE even I added public IP (external IP) of my GCE instance as a authorized network. It works when I add "0.0.0.0" into authorized network. Obviously I don't want to do that. The authorized network setting may be the cause. But I can't find out it. Does anyone know about this.
I'm using Google Cloud SQL version 2 beta. I am trying to connect from GCP cloud console. Although it may be not necessary, I changed external IP setting from ephemeral to static but it didn't work.
mysql -u root -p -h xxxx <--- I can login normally if I add "0.0.0.0" into authorized network.
I've double checked this same question..
Linking Google Compute Engine and Google Cloud SQL
1. Ensure your Cloud SQL instance has an IPv4 address.
2. Find out the public IP address of your GCE instance and add it as an authorized network on your Cloud SQL instance.
3. Add a MySQL username and password for your instance with remote access.
4. When connecting from GCE use you standard MySQL connection system (e.g. mysqli_connect) with the username and password you just set up, connecting to the IPv4 address of your Cloud SQL instance.
Edit 1
I noticed this description.
Note: Connecting to Cloud SQL from Compute Engine using the Cloud SQL Proxy is currently available only for Cloud SQL Second Generation instances.
https://cloud.google.com/sql/docs/compute-engine-access
Does it mean that I have to use the Proxy..?
Edit 2
$ mysql -u root -p -h (Cloud SQL Instance's IP)
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on '(Cloud SQL Instance's IP)' (110)
Edit 3
Does it mean that I have to use the Proxy..?
According to the official document as Vadim said, Cloud SQL Proxy seems to be optional but it sounds better for security, flexibility and also the price. (static IP will be charged. However, the proxy setting may be complicated for me..)
https://cloud.google.com/sql/docs/compute-engine-access
If you are connecting to a Cloud SQL First Generation instance, then you must use its IP address to connect. However, if you are using a Cloud SQL Second Generation instance, you can also use the Cloud SQL Proxy or the Cloud SQL Proxy Docker image.
Edit 4
I found the reason... I was stupid... I tried connect from Google Cloud Shell but that was not my gce instance. It works when I try to connect from my gce instance.
Did you add the public IP of the GCE VM under authorized networks?
From your post:
2. Find out the public IP address of your GCE instance and add it as an authorized network on your Cloud SQL instance.
The official documentation is here:
https://cloud.google.com/sql/docs/external#appaccessIP
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.
