Using MySQL 5.5.27, in my.cnf I have:
[mysql]
sql_mode=ANSI
Upon starting the mysql console I get:
unknown variable 'sql-mode=TRADITIONAL'
The MySQL doc Server SQL Modes shows that option, so why does it not work?
(If it helps, I am on OSX Lion)
Also, here is a pastebin showing the things another person has tried, with no solution.
sql-mode should be in the [mysqld] section, not in the [mysql] section; if you move sql-mode=ANSI to the [mysqld] section, it should work.
I'm pretty certain the reason it isn't working is because it is an argument for mysqld and not the client. I came up with an alternative way that you could do this instead. Edit your users my.cnf i.e. ~/.my.cnf to be something like this:
[client]
init-command="set sql_mode='TRADITIONAL'"
In config file you should use sql-mode name instead (with dash, not underscore)
http://dev.mysql.com/doc/refman/5.5/en/server-options.html#option_mysqld_sql-mode
And as #cogsmos pointed out, you should put it [mysqld] section

I wanted to disable some options in the MySql server strict mode, but for some reason I'm not even able to find its configuration file (my.cnf)
Currently installed MySql:
Ver 14.14 Distrib 5.7.20, for macos10.12 (x86_64)
Output generated by
mysql --help
Default options are read from the following files in the given order:
/etc/my.cnf
/etc/mysql/my.cnf
/usr/local/mysql/etc/my.cnf
~/.my.cnf
But there is no such file as my.conf
I had done some research work on SO but none of the advises has worked for me.
What I'm supposed to do?
There are defaults built into MySQL. The configuration file(s), if any, override the defaults.
Note that the config files are not looked at except during startup. So, editing or creating such a file has no effect until you restart mysqld.
If you mess up the syntax, mysqld will not start. Then you need to find the error, either during startup, or in a log file. (Or you could ask here "what is my syntax error".)
As for the location, and name, of the config files that will be used:
$ mysql --help
gives you the list for mysql, but perhaps you need it for the server, so try
$ mysqld --help --verbose
gives you long output; maybe 50 lines from the top, you should see something like:
Usage: mysqld [OPTIONS]
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf
You asked about my.conf; was that a typo?
Regardless, If those files are missing, you can create them, make them readable by mysql, and put things into it preceded by [mysqld] so that the server will see them.
Personal override
Regardless of what is in the defaults and/or config files, you can add to the last file given. In the examples above that is 'hidden' .my.cnf in your home directory. All you need to do is create a few lines:
[mysql]
some_setting = somevalue
[client]
some_setting = somevalue
That helps for the "mysql" commandline tool and/or other clients (maybe).
But if you need to make changes to the server mysqld, it needs to be in one of the other files. Again, the minimum is something like
[mysqld]
some_setting = somevalue
Note the mysqld to refer to the server. And remember to restart the service.
Another note: If you see (in an existing config file), !includedir ..., then go to that directory to find any number of further files. You could add your own file, say z.cnf (so it would be picked last) with the two (or more) lines as indicated above.
If you have installed Mysql 8 or Above using the package installer from mysql website, then follow what i did
Create the config file in your home directory vim ~/.my.cnf
Do open System preferences in mac
Then Select the configuration file you created on the option.

I had the urgent need to configure some specific stuff in MySQL 5.7 on my developer machine, a MacBook Pro running Mac OS Sierra. Unfortunately, I did not find a my.cnf file that could be customized anywhere?
Internet research showed that MySQL Database Server on Mac OS runs without a my.cnf config file by default, simply started with default values.
Luckily, it is pretty simple to customize the MySQL Server installation by creating and editing a custom my.cnf file like this:
sudo cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
Then edit / customize the /etc/my.cnf file as required and restart your MySQL Server.
Or you can refer to this answer
You could try:
$ locate mysql | grep my.cnf
It should reveal the location(s) if it exists.
I an currently using mysql server 5.6 in windows 10. while using mysql, an error keeps appearing that goes as something like this "the following column does not have a default value" i read on the internet that i can solve this problem if i change the sql_mode. It is currently set to
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
I took this from "my-default.ini" file in "mysql server 5.6" folder. I read several other answers that say that if you want to permanently change your sql_mode, you should do it through the "my-default.ini" file. So what i did was, i run my notepad as administrator, then i browsed to open "my-default.ini" file that is found in:
c:\programs files (x86)\mysql\mysql server 5.6\my-default.ini
when i opened the file, i modified the last line:
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
to
sql_mode=
then i saved the file, closed it. then by using task manager i restarted my sql sever:
task manager >> services >> mysql56
This is the whole process that should permanently modify my sql_mode. when i look in my "my-default.ini" file, the last line is still modified. but if i log into mysql through the command line and view my sql_mode with the following code:
select ##sql_mode;
I get that my sql_mode is
STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
I want all this to be removed (permanently) in order for my error to disappear. IF i try to modify the sql_mode from the command line by using:
set ##global.sql_mode="";
It worked, but when i restarted MySQL, everything was back as it was before.
Can someone please tell me what i am doing wrong? and if there is another way to solve this problem.
UPDATE: Sorry, forgot you were using Windows 10. I'm not sure how to deal with this issue in Windows but maybe try copying my-default.ini to my.ini and changing that setting. Sorry for confusion.
Not sure if you can set your sql_mode to nothing but try changing the value in your /etc/mysql/my.cnf file. If that folder/file doesn't exist, create it and try setting sql_mode under [mysqld] like this:
[mysqld]
sql_mode=
I just did this same thing only I set the sql_mode to NO_ENGINE_SUBSTITUTION.
If you have MySQL Workbench installed, check the Server Status for the base directory of your instance. You should find a my.ini file there that keeps your changes.
sql_mode need to add to file /etc/init.d/mysql as a argument to start like:
$bindir/mysqld_safe --datadir="$datadir" --pid-file="$mysqld_pid_file_path" --sql-mode="" $other_args >/dev/null 2>&1 &
Restart MySQL database server to apply new config.
In MYSQL 8 and ubuntu server 20.xx I had to add:
sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTIO
To file
/etc/mysql/mysql.conf.d/mysqld.cnf
In order that the setting stay persistent after server restart
Disclaimer:
this was the only place it actually worked, I have no idea what's the good practice where to add these custom settings but it 'ain't stupid if it works'. Somebody can tell me.
I tried the other options I found on forums:
my.cnf did not work creating
custom cnf did not work
adding it to mysql.cnf did not work
I've been trying to set up two databases as master & slave.
I followed the famous guide here:
https://dev.mysql.com/doc/refman/5.1/en/replication-howto-existingdata.html
But no luck on my slave server,
The issue I'm having is setting the server-id variable.
No matter where I define it (I looked into all the possible cnf files that might allow me to define the variable)
I tried to define it like so:
[mysqld]
server-id = 2
I also tried setting it by using SET GLOBAL server_id but obviously, it didn't save the setting.
when I do:
SHOW VARIABLES LIKE 'server_id'
It returns
server_id 0
Among the cnf files I've looked into are:
etc/mysql/mysql.conf.d/mysqld.cnf
etc/mysql/mysql.conf.d/mysqld_safe_syslog.cnf
etc/mysql/conf.d/mysql.cnf
etc/mysql/debian.cnf
etc/mysql/mysql.cnf
usr/my.cnf
usr/my-new.cnf
usr/etc/my.cnf
My MySQL server is running on Ubuntu.
And if it matters, I start it by typing:
service mysql start
I'd love to know where else I could look to fix this issue.
Thanks a bunch!
Additional Notes:
MySQL Ignoring the global conf file
I received this warning a couple of times and it disappeared when I returned the chmod to 644 on the etc/mysql folder, although every thing stated above was attempted using both 644 and 777 permissions, with 644 the warning disappears.
I know it's to late, but for those who will make the mistake.
It's server_id and not server-id:
[mysqld]
server_id = 2
For me it worked by renaming the from /etc/mysql/conf.d/my.cnf to /etc/mysql/conf.d/my.ini
I'm not sure of the exact reason for that (feel free to edit this answer and add to it).
I tried out various combinations:
Keeping the variable as: server-id and server_id
Keeping the group/section as: [mysql] and [mysqld]
Renaming the file to: my.cnf , mysqld.cnf, mysql.cnf, my.ini
You can keep trying various combinations out of the above options, it should definitely work. :)
How to give a specific .my.cnf config file to the mysql command line?
$ mysql --my-config=.my.cnf
The --defaults-file option lets you specify which options file you want to use. It would be a good idea to give it the full path to your options file.
mysql --defaults-file=/home/user/.my.cnf database
In here: http://dev.mysql.com/doc/refman/5.5/en/option-files.html it says you can also specify "defaults-extra-file" for additional params. Otherwise it defaults to the various my.cnf (depending on OS).
how can i save permanently settings of MySQL ?
i got MySQL from WAMP, and there is no my.cnf file, there is a my.ini file !
how can i set some global variable,
Drive:\wamp\bin\mysql\mysql5.5.8\my.ini
this is the place to save settings.
WAMP uses the my.ini file.
To get to your my.ini file, just click the WAMP tray icon and hover over the 'MySQL' menu, and click 'my.ini'.
Edit your my.ini file and under the [mysqld] section, add this:
setting-name=setting-value , example: event-scheduler=on
restart all services
You do not need to use quotes around either the setting or value.
Global system variables must be specified using the command line or SQL commands (runtime/session) or by configuration file (permanent).
I have had the same question because in WAMP we only have a my.ini file instead of my.conf.
Through a SQL statement, proceeded as follow:
mysql> SET global max_heap_table_size=524288000;
mysql> SET global tmp_table_size=524288000;
but when restarted the server, the query:
select ##global.tmp_table_size, ##global.max_heap_table_size
returned the old values by default.
Then edited my.ini file ading the following statements:
max_heap_table_size=524288000
tmp_table_size=524288000
and the changes were permanent.
