There is nothing more to be said:
SELECT gen.TABLE_SCHEMA , gen.TABLE_NAME , (select count(TABLE_NAME) from information_schema.columns idx where idx.TABLE_SCHEMA = gen.TABLE_SCHEMA and idx.TABLE_NAME=gen.TABLE_NAME ) as COLUMN_NUM , (select count(TABLE_NAME) from information_schema.columns idx where idx.TABLE_SCHEMA = gen.TABLE_SCHEMA and idx.TABLE_NAME=gen.TABLE_NAME and COLUMN_KEY != "" ) as INDEX_NUM_ALL , (select count(TABLE_NAME) from information_schema.columns idx where idx.TABLE_SCHEMA = gen.TABLE_SCHEMA and idx.TABLE_NAME=gen.TABLE_NAME and COLUMN_KEY = "PRI" ) as INDEX_NUM_PRI , (select count(TABLE_NAME) from information_schema.columns idx where idx.TABLE_SCHEMA = gen.TABLE_SCHEMA and idx.TABLE_NAME=gen.TABLE_NAME and COLUMN_KEY = "UNI" ) as INDEX_NUM_UNI , (select count(TABLE_NAME) from information_schema.columns idx where idx.TABLE_SCHEMA = gen.TABLE_SCHEMA and idx.TABLE_NAME=gen.TABLE_NAME and COLUMN_KEY = "MUL" ) as INDEX_NUM_MUL from information_schema.tables gen where true and gen.TABLE_SCHEMA !='mysql' and gen.TABLE_SCHEMA!='performance_schema' and gen.TABLE_SCHEMA!='information_schema' ; +-----------------+-----------------------+------------+---------------+---------------+---------------+---------------+ | TABLE_SCHEMA | TABLE_NAME | COLUMN_NUM | INDEX_NUM_ALL | INDEX_NUM_PRI | INDEX_NUM_UNI | INDEX_NUM_MUL | +-----------------+-----------------------+------------+---------------+---------------+---------------+---------------+
MySQL, Percona, MariaDB long running processes clean up one liner
April 30, 2015
Leave a comment
There are tools like pt-kill from the percona tool kit that may print/kill the long running transactions at MariaDB, MySQL or at Percona data instances, but a lot of backup scripts are just some simple bash lines.
So checking for long running transactions before the backup to be executed seems to be a step that is missed a lot.
Here is one line that might be just added in every bash script before the backup to be executed
Variant 1. Just log all the processlist entries and calculate which ones were running longer than TIMELIMIT:
$ export TIMELIMIT=70 && echo "$(date) : check for long runnig queries start:" >> /tmp/processlist.list.to.kill && mysql -BN -e 'show processlist;' | tee -a /tmp/processlist.list.to.kill | awk -vlongtime=${TIMELIMIT} '($6>longtime){print "kill "$1";"}' | tee -a /tmp/processlist.list.to.kill
Variant 2: Log all the processlist, calculate the calculate which processes are running longer than TIMELIMIT, and kill them before to execute the backup:
$ export TIMELIMIT=70 && echo "$(date) : check for long runnig queries start:" >> /tmp/processlist.list.to.kill && mysql -BN -e 'show processlist;' | tee -a /tmp/processlist.list.to.kill | awk -vlongtime=${TIMELIMIT} '($6>longtime){print "kill "$1";"}' | tee -a /tmp/processlist.list.to.kill | mysql >> /tmp/processlist.list.to.kill 2>&1

How to relabel two identical TOSHIBA 1Tb USB 3.0 disks in a view to be auto mounted properly at XBMC
September 19, 2014
Leave a comment
I have two identical 1TB Toshiba USB 3.0 disks, and when I attach them to my RaspberryPI running XBMC, they appear as identical TOSHIBA EXT mounts at the GUI
After searching at the udev rules, I decided just to rename the partitions …

Fedora release 20 (Heisenbug) enable client OpenVPN service on boot
August 21, 2014
Leave a comment
In short, I had to deal with the Fedora EVIL EVIL EVIL !!! Systemd
I found my openvpn startup script useless ..
Managed to set the VPN at the Network Manager just loading the openvpn config file, but I wanted to be started on boot … because out of the blue my Fedora 20 Gnome boot hanged on the blue logo !!! This is another story to be told.
Anyway, back to the OpenVPN issue, the steps to do make it start on boot, following the instructions at http://fedoraproject.org/wiki/Openvpn
1. Set the keys and the config file at /etc/openvpn
root@outoutdragkh.f20:[Thu Aug 21 01:30:06][~]$ cd /etc/openvpn/ root@outdragkh.f20:[Thu Aug 21 01:30:10][/etc/openvpn]$ ls keys outdragkh.client.conf
2. Fix selinux context of the config files :
root@outdragkh.f20:[Thu Aug 21 01:30:10][/etc/openvpn]$ restorecon -Rv /etc/openvp
3. Check the general openvpn service file:
root@outdragkh.f20:[Thu Aug 21 01:30:32][/etc/openvpn]$ ls /lib/systemd/system/openvpn\@.service /lib/systemd/system/openvpn@.service root@outdragkh.f20:[Thu Aug 21 01:30:51][/etc/openvpn]$ cat /lib/systemd/system/openvpn\@.service [Unit] Description=OpenVPN Robust And Highly Flexible Tunneling Application On %I After=syslog.target network.target [Service] PrivateTmp=true Type=forking PIDFile=/var/run/openvpn/%i.pid ExecStart=/usr/sbin/openvpn --daemon --writepid /var/run/openvpn/%i.pid --cd /etc/openvpn/ --config %i.conf [Install] WantedBy=multi-user.target
4. Set the systemd start scripts for the outoutdragkh.client.conf
root@outdragkh.f20:[Thu Aug 21 01:30:55][/etc/openvpn]$ ln -s /lib/systemd/system/openvpn\@.service /etc/systemd/system/multi-user.target.wants/openvpn\@outdragkh.client.service root@outdragkh.f20:[Thu Aug 21 01:32:04][/etc/openvpn]$ ls /etc/systemd/system/multi-user.target.wants/openvpn@outdragkh.client.service /etc/systemd/system/multi-user.target.wants/openvpn@outdragkh.client.service
5. Enable the dragkh OpenVPN service
root@outdragkh.f20:[Thu Aug 21 01:32:12][/etc/openvpn]$ systemctl -f enable openvpn@outdragkh.client.service rm '/etc/systemd/system/multi-user.target.wants/openvpn@outdragkh.client.service' ln -s '/usr/lib/systemd/system/openvpn@.service' '/etc/systemd/system/multi-user.target.wants/openvpn@outdragkh.client.service'
6. Start the dragkh OpenVPN service
root@outdragkh.f20:[Thu Aug 21 01:32:30][/etc/openvpn]$ systemctl start openvpn@outdragkh.client.service
root@outdragkh.f20:[Thu Aug 21 01:32:49][/etc/openvpn]$ systemctl status openvpn@outdragkh.client.service

Resolving deltas: 100% (18716/18716), done.
2. Update the CentOs install just in case before to play with it:
root@webscalesql-5.6.clean:[Mon Mar 31 11:40:35][/opt/installs]$ yum update -y
3. Compile it :
Note : The final part of the prompt here “[webscalesql-5.6.17]” id the actual git branch version.
root@webscalesql-5.6.clean:[Mon Mar 31 12:23:22][/opt/installs/webscalesql-5.6] [webscalesql-5.6.17]$ cmake . -DBUILD_CONFIG=mysql_release -DENABLE_DOWNLOADS=1 -bash: cmake: command not found
3.1 No Cmake ? The CentOS install was done without cmake etc dev tools as at production they are not needed.
Now, we need it: Install cmake
root@webscalesql-5.6.clean:[Mon Mar 31 12:23:34][/opt/installs/webscalesql-5.6] [webscalesql-5.6.17]$ yum install cmake -y ....

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/local/mysql/bin/mysqladmin -u root password 'new-password'
/usr/local/mysql/bin/mysqladmin -u root -h webscalesql-5.6.clean password 'new-password'
Alternatively you can run:
/usr/local/mysql/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; /usr/local/mysql/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems at http://bugs.mysql.com/

New default config file was created as /usr/local/mysql/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
WARNING: Default config file /etc/my.cnf exists on the system

Connect MySQL to sqlite3 database or to flat txt file via CONNECT engine of MariaDB 10.0.7 on Fedora/CentOS
January 31, 2014
Leave a comment
You might don’t know that, but the MariaDB engines are amazing ..
More info you can find here:
https://mariadb.com/kb/en/mariadb-storage-engines/
I was teased by CONNECT engine : https://mariadb.com/kb/en/connect/
What is good for ? Well, I leave that to your imagination, as you could have MariaDB as a spider connected and managing InnoDB tables, flat files, MS ACCESS databases, MS Excel files … all that in same time.
So how to use it?
By the documentation :
1. https://mariadb.com/kb/en/loading-the-connect-handler/
check if there is CONNECT already installed, if not, install it:

Its not installed by default for MariaDB 10.0.7
So lets install it:
mysql root@mariadb-10.0.7:[Wed Jan 29 09:36:19 2014][(none)]> INSTALL PLUGIN CONNECT SONAME 'ha_connect'; ERROR 1126 (HY000): Can't open shared library '/usr/lib64/mysql/plugin/ha_connect.so' (errno: 2, cannot open shared object file: No such file or directory)
My first install failed and I had to install MariaDB-connect-engine package from MariaDB

Now, sqlite3
UnixODBC was installed along with the MariaDB-connect-engine package, but I was not a able to find SQLite UnixODBC driver installed. Neither I was able to get if from the Fedora repos.
Checking for the http://www.unixodbc.org/drivers.html I ended up with compiling the SQLite ODBC Driver from http://www.ch-werner.de/sqliteodbc/
The instructions are good enough for me:
1. get the source from
$ wget http://www.ch-werner.de/sqliteodbc/sqliteodbc-0.996.tar.gz
2. Untar it :
$ tar xvf sqliteodbc-0.996.tar.gz
3. go to the source directory:
$ cd sqliteodbc-0.996
4. compile it
$ ./configure .. ... configure: WARNING: SQLite4 header file and source not found configure: error: No usable SQLite header/library on this system
4.1 In case you get the No usable SQLite header/library error, installs the sqlite-devel package
$ yum install sqlite-devel sqlite-devel.x86_64 0:3.6.20-1.el6 will be installed
4.2 run configure again
$ ./configure .. ... checking for ODBC headers and libraries... no configure: error: ODBC header files and/or libraries not found
4.3 In case you get error: ODBC header files and/or libraries not found, install the unixODBC-devel package:
$ yum install unixODBC-devel Package unixODBC-devel.x86_64 0:2.2.14-12.el6_3 will be installed
4.4 run configure again:
$ ./configure make make install
5. Check the installed ODBC drivers:
$ odbcinst -q -d [PostgreSQL] [MySQL] $ cat /etc/odbcinst.ini # Example driver definitions # Driver from the postgresql-odbc package # Setup from the unixODBC package [PostgreSQL] Description = ODBC for PostgreSQL Driver = /usr/lib/psqlodbc.so Setup = /usr/lib/libodbcpsqlS.so Driver64 = /usr/lib64/psqlodbc.so Setup64 = /usr/lib64/libodbcpsqlS.so FileUsage = 1 # Driver from the mysql-connector-odbc package # Setup from the unixODBC package [MySQL] Description = ODBC for MySQL Driver = /usr/lib/libmyodbc5.so Setup = /usr/lib/libodbcmyS.so Driver64 = /usr/lib64/libmyodbc5.so Setup64 = /usr/lib64/libodbcmyS.so FileUsage = 1
6. Install the sqlite3 odbc driver:
$ nano /etc/odbcinst.ini # Example driver definitions # Driver from the postgresql-odbc package # Setup from the unixODBC package [PostgreSQL] Description = ODBC for PostgreSQL Driver = /usr/lib/psqlodbc.so Setup = /usr/lib/libodbcpsqlS.so Driver64 = /usr/lib64/psqlodbc.so Setup64 = /usr/lib64/libodbcpsqlS.so FileUsage = 1 # Driver from the mysql-connector-odbc package # Setup from the unixODBC package [MySQL] Description = ODBC for MySQL Driver = /usr/lib/libmyodbc5.so Setup = /usr/lib/libodbcmyS.so Driver64 = /usr/lib64/libmyodbc5.so Setup64 = /usr/lib64/libodbcmyS.so FileUsage = 1 [SQLite] Description=SQLite ODBC Driver Driver=/usr/local/lib/libsqliteodbc.so Setup=/usr/local/lib/libsqliteodbc.so Threading=2 $ odbcinst -q -d [PostgreSQL] [MySQL] [SQLite]
So the SQLite ODBC driver was installed.
In a view to trace the CONNECT engine , its good to create connect.ini file in the mysql directory
$ cat /var/lib/mysql/connect.ini [CONNECT] Trace=2
The CONNECT engine errors will be in the mysql error.log, in my case mariadb-10.0.7.err
How to create a MySQL table using sqlite3 database?
create the sqlite3 table :

It seems you have your SQLite db in a folder where your database user /mysql/ must have write permissions,but does not.
Most probably you have selinux activated.
How to fix that without disabling the selinux? The best way is move the SQLite db file to the mysql data directory : /var/lib/mysql/, or to create a separated directory where mysql shell user has write permissions.
