I've run into a problem. I have a Google Cloud SQL instance (Second Generation) and I use it as a master to run my own replication slave from. It all works fine, but I'm trying to change the connection to use SSL and failing. I have followed a variety of guides...
I've tried putting this in my.cnf
[client]
ssl-ca=server-ca.pem
ssl-cert=client-cert.pem
ssl-key=client-key.pem
I've also tried putting those lines under the [mysqld] heading. I've changed the slave to use SSL using
CHANGE MASTER TO MASTER_SSL=1;
I've put the word ssl in my.cnf (this causes the connection to fail). I've also tried to change the slave using
CHANGE MASTER TO MASTER_SSL=1, MASTER_SSL_CA = 'ca-cert.pem', MASTER_SSL_CERT = 'client-cert.pem', MASTER_SSL_KEY = 'client-key.pem';
Nothing will make it use SSL. If I query the slave is says SSL is disabled but putting ssl in the [mysqld] section stops replication working.
The certificates themselves are all downloaded from the instance and work fine in a PHP database class I use to connect from a different server.
Does anyone have any experience with this? I know it's failing as I've used tcpdump to watch the port and also \s in the MySQL console says SSL is off.
MySQL on the slave is version: 5.6.38-log MySQL Community Server (GPL).
On Google it reports MySQL 5.6
Thanks in advance!
Found the issue, I hadn't installed mysql-devel, now working

I just use IDEA recently and want to use IDEA to connect MySQL(8.0.12).but the IDEA indicate below
However, I use cmd could connect to my database,thus I did not configure out the problem.
I am in serah of many ways to solve this problem on tech forum but those are not working.
change mysql to lower version driver
set time_zone
add properties on url
There are a couple of things to check to solve the 'Communications links' failure.
One thing in particular is to check whether your MySQL server accepts TCP connections. In your terminal, it looks like you are using named pipes.
Make sure your MySQL server allows TCP connections; check for the bind-address configuration in mysql.ini under [mysqld] section. Its value should be at least 127.0.0.1, or set it as * to bind to all (not always a good idea).
Another point is the skip_networking configuration. Check if you have that, and remove and restart MySQL server. I believe this is set by default when you are installing MySQL.
(Also note that 8.0.17 is 'ancient' already).
I have FreeBSD with mysql server and want to connect navicat with them. On vBox I have bridged network (192.168.0.225). I can ping to this from my system (192.168.0.135)
With ssh and ftp, it isn't a problem.
navicat error: 2003 -can't connnect to mysql server on 192.168.0.225.
10061 unknown error
It's a navicat's bug.
Delete the connection config where in navicat/servers/your-connection-name.
Then try to create a new connection and run.
It is likely, your mysqld is only listening on the local socket (/tmp/mysql.sock or some such). That's the most secure mode.
To make it more promiscuous, you'll need to configure the server to listen for TCP-connections as well.
Look for the bind-address setting in the [mysqld] section of /usr/local/mysql/my.cnf. You'll, probably, need something like
bind-address = 192.168.0.225
Consult this tutorial for more information on how to then authorize remote users -- MySQL allows configuring different passwords and access-policies depending on the where the connection is coming from.
You've probably disabled all apps from the service.
Click from start menu System Configuration
Click Services
Hide all Microsoft Services

I use Nginx for my webserver, and have MariaDB installed with PhpMyAdmin as webgui. The server which it runs is public, and not a private local ip home server. I have also binded a domain to this server. To run everything, I've chosen to use Docker containers. Everything is setting up really well from getting images and so ever. At the moment, I have Nginx working with my main domain and subdomains. Surely, I came at a breakpoint. I wanted, for my (remote) connection to PhpMyAdmin to use tls certificates between PMA itself and MariaDB. In this case, it is needed for PMA to let me know that it is secured. So, that this message is gone:
And after the login, under database as Server Connection: SSL not being used - that also changes.
But, the important thing is that I have a my.cnf for my MariaDB instance. In that file, I have a couple lines of what's needed:
[mysqld]
### MySQL Server ###
## Securing the Database with ssl option and certificates ##
ssl = true
ssl-ca = /etc/mysql/ssl/ca-cert.pem
ssl-cert = /etc/mysql/ssl/server-cert.pem
ssl-key = /etc/mysql/ssl/server-key.pem
ssl-cipher = DHE-RSA-AES256-SHA
My cert files are correctly in that path, and inside the MariaDB container listed with the cipher:
But, it says yes for the have_openssl and for the have_ssl that it is disabled. I've done research about this problem in the past days and I cannot get it to work properly. Also, I checked the permissions on the files and made sure there are execute rights. I readed somewhere else that in normal situation without the containers, it needs the permissions set to be for the mysql user. Since I do not have a mysql user, do I ask if it is needed to make one.
How can I fix this issue, that MariaDB has 'have_ssl' on yes and it is configured right? Also, if MariaDB is set up. Do I need to fill in the config for PMA with the files or?
I have installed MySQL Query browser 1.2.11 on my windows 8 machine, but i open MySQL Query Browser it show me error like bellow image
when i click on ping button it works fine for me.
i google this problem and disable my windows firewall still it same error on open MySQL Query Browser
The server not starting mostly happens with permission issues or installation errors. Please check if there is any permission issues or try to reinstall mysql.
Please check the following link for more info Can't connect to [local] MySQL server
Error No. 2003: Can't connect to MySQL server on 'localhost' (or some other host)
simply means that connection is not possible for one of the following (or similar) reasons:
There is no MySQL server running at the specified host
Connection to the MySQL server is not allowed using TCP-IP. Check the 'skip-networking' setting in the MySQL configuration file (my.ini on Windows, my.cnf on Unix/Linux). It shall be commented out like '#skip-networking'. If it is not commented out, then do it and restart the MySQL server for the change to take effect. Needs to connect using TCP-IP.
Some networking issue prevents connection. It could be a network malconfiguration or a firewall issue.
This error usually occur when mysql service get stopped.
In Windows OS:
Right click on my computer>> manage>>services and application>>services
Then search for mysql. Right click on mysql then properties from there select "start up type" after that click on start.
Now login to your mysql. It should be working fine.
seems like service went down.
please start the service if it stopped .
service mysqld start
go to start-> run-> services.msc
in this search for MySQL right click and 'start'...
now you can login again...Query Browser will start again...
I use WampServer (Apache, PHP, MySQL) and have no problems when some kind of network adapter(wireless or lan) is connected (i.e. Local Area Connection has status connected) even if i am not connected to the internet (for example when i am connected to the router but that is not connected to the internet).
When there is no network connection, I get a php error like MySQL could not connect to 127.0.0.1 on port 3306.
Interestingly, telnet 127.0.0.1 3306 says that it could not connect to the port, even when the server and MySQL are running fine (i.e. when some kind of local area connection is connected).
So I turned off all kinds of firewall (antivirus and Windows) but still no difference in anything. And that is why this issue is quite puzzling.
Things I have already tried (will update this list along the way):
The skip-networking directive in my.ini.
You could modify your MySQL server and client configuration to connect to one another using a named pipe instead of a TCP/IP loopback connection. That way, the current state of the network connection should have less impact.
To do so, start the server with --enable-named-pipe or the corresponding config file setting, and execute the client with --pipe or --protocol=PIPE. Similar configurations should be available for your PHP connector as well. It may depend on which library you use there, and whether or not it will take the mentioned configuration settings from the my.ini file (settings without leading -- there).
