I have downloaded MYSQL via:
bash <(curl -Ls http://git.io/eUx7rg)
Prior to installing I've completely uninstalled previous components via:
http://community.jaspersoft.com/wiki/uninstall-mysql-mac-os-x
I've had to modify permissions in order to see the log file and see primarily permissions errors. Also, when I try:
type mysql
The result, in terminal, points to a directory that does not exist on my local system. When I trace the path to the executable (via Finder) I get the following error in Terminal:
/usr/local/mysql-5.6.19-osx10.7-x86_64/bin/mysql ; exit;
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2)
logout
Also, when I look at my.conf file, everything is asterisked out:
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html

Had the same problem. Had to switch machines for a week and installing MySQL on "OS X 10.9.3 (13D65)" would not work. Had to wipe the account clean and reinitialize the user to get it going. Apparently there was still an old mysql which wasn't uninstalled completely. Google "uninstall mysql manually"
The access denied happens sometime when the grant is given to the interface 127.0.0.1 but not to localhost.
Try granting access to %, 127.0.0.1, and localhost.

Hello dear StackOverflow community,
I have a large WordPress site that now crashes the database by creating dozens of Creating sort index tasks with:
SELECT t.*, tt.*
FROM wp_terms AS t
INNER JOIN wp_term_taxonomy AS tt ON t.term_id = tt.term_id
WHERE tt.taxonomy IN ('categories')
ORDER BY t.name ASC
Those run for more than 20 seconds +. Afterwards its "sending data" with the same SQL query. The server is using an AMD epyc cpu and shouldn't have any problems (even though the database is large) and it did not have until it suddenly seems to be stuck.
Shouldn't it be caching this query anyways?
The mariadb my.cf config looks like:

I restarted mariadb, but the advisor mentions a huge rate of opening tables (same for files). The server is running only for 15 minutes. Is this due to the short time or do I have to change the settings (before the huge amount of Creating sort index tasks, the server was stable)
Issue:
The rate of opening tables is high.
Recommendation:
Opening tables requires disk I/O which is costly. Increasing table_open_cache might avoid this.
Justification:
Opened table rate: 1.26 per second, this value should be less than 10 per hour
Used variable / formula:
Opened_tables / Uptime
Test:
value*60*60 > 10
I would be awesome if somebody has an idea, what to do about that problem
On server 1 (lets call it 1.1.1.1 , I have Wordpress installed, which has its own MySQL database.
On server 2 (lets call it 2.2.2.2) , I have only MySQL on Ubuntu, with PhpMyAdmin installed.
I am attempting to connect FROM Wordpress (functions.php) FROM server 1, to server 2's MySQL database through the following:
$mydb = new wpdb('rruser','password','dbname', '2.2.2.2');
Following this connection, everything else is fine.
Upon loading the shortcode through a page, the page does not load the content in the shortcode. I am assuming the connection has timed out.
Please can someone advise how I can go about connecting to an external database?
I have created a new user on "2.2.2.2" and granted priveleges to "dbname".
CREATE USER 'rruser'#'1.1.1.1' IDENTIFIED WITH mysql_native_password AS '***';`
`GRANT USAGE ON *.* TO 'rruser'#'1.1.1.1' REQUIRE NONE WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0;`
`GRANT ALL PRIVILEGES ON `rail`.* TO 'rruser'#'1.1.1.1';
My MySQL my.cnf file looks like the following on the remote server which I would like to connect to (2.2.2.2)
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html
#
# * IMPORTANT: Additional settings that can override those from this file!
# The files must end with '.cnf', otherwise they'll be ignored.

!includedir /etc/mysql/mysql.conf.d/

Many thanks in advance.
I have resolved my problem by adding bind-address to 2.2.2.2's my.cnf file, as well as allowing mysql's ports in UWF, including TCP and 8080.
Upon rebooting my server the problem is resolved
i've looked up every tutorial on how to fix this and nothing worked so far,
I'm getting this error
No connection could be made because the target machine actively refused it
i'm using linux centos7 mysql version
mysql Ver 14.14 Distrib 5.6.32, for Linux (x86_64) using EditLine wrapper
blow is my.cnf
also i had to create my own my.cnf as when i installed mysql it didn't have one located i put this into etc/my.cnf it's running the cnf as it's taken mysql out of strict mode.

Ok, I am assuming that you have installed this on a completely different machine (as opposed to a Virtual Host on your Windows box).
You need to make sure that port 3306 is open on your DB server first and foremost. You can check this with a port checker (there are plenty of free ones online).
Then, with the user you are trying to connect with, you need to make sure that user has access from the origin IP address (i.e. the IP on your Windows machine). This can be done with the following code from the mysql prompt.
GRANT ALL PRIVILEGES ON <your db name>.* TO <your user>#<your ip> IDENTIFIED BY '<your password>';
A less secure option would be to allow all inbound IPs by using the % wildcard.
After this you need to run the following command.
FLUSH PRIVILEGES;
That should be it.

Thank you very much in advance.
I just found answer myself. I had my.ini in two plases. one in C drive and the other one in D drive. That caused the confusion. As soon as I renamed one of the my.ini, the problem didn't happen.
I'm working with MySQL Workbench 6.0. I built a schema from a .sql file. It has 1024 tables. when I connect it to local host only 47 tables seem to make it. I check with this command
SELECT COUNT(*) FROM information_schema.tables WHERE table_schema = "my_schema";
Why would it just leave behind the other 977 tables? is it a memory allocation thing? or an issue with my configuration?
Edit 1
result from the MySQL command
SHOW ENGINES;
Edit 2
I checked out the .ini file that my local connection looks at. It uses the default one in
C:\Program Files\MySQL\MySQL Server 5.6
This is its content of my-default.ini

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
so because this is the file its reading and I've not made any changes is there a memory issue for a database that has the large number of tables like mine? Or should I be leaving this allone for my local connection and be changing the settings through MySQL Workbench?
Edit 3
Blow is the results of SQL command
SHOW GRANTS;
First confirm that sql file has all 1024 tables.
Second check that the engine of tables in sql file is present or not in your database server with command SHOW ENGINES:
