I installed xampp. After I type sudo /opt/lampp/lampp start into terminal, I get
$ sudo /opt/lampp/lampp start
Starting XAMPP for Linux 5.6.23-0...
XAMPP: Starting Apache...ok.
XAMPP: Starting MySQL...ok.
XAMPP: Starting ProFTPD...ok.
I changed the root password in /opt/lampp/phpmyadmin/config.inc.php
The password in localhost/phpmyadmin agrees with the change made in the config.inc.php file.
When I type mysql -u root -p into terminal I get
The program 'mysql' can be found in the following packages:
* mysql-client-core-5.5
* mariadb-client-core-5.5
* mysql-client-core-5.6
* percona-xtradb-cluster-client-5.5
Try: sudo apt-get install <selected package>
I installed mysql-client-core-5.6
$ sudo apt-get install mysql-client-core-5.6
[sudo] password for experiment:

After installing the client, when I typed mysql -u root -p into terminal I got

Some threads suggest that multiple instances of mysql could be running.
When I type ps ax | grep mysql into terminal, I get
$ ps ax | grep mysql

11112 pts/6 S+ 0:00 grep --color=auto mysql
I don't know how to interpret the output. Is this one instance of mysql?
Some threads suggest making changes to the my.cnf file. I don't have one. I do have a etc/mysql/my.cnf.bak file. Where should I put the my.cnf file?
Should I be able to use the mysql command line after installing xampp only or do I need to install a client?
My ultimate goal is to have a system where I can use xampp, Workbench, NetBeans, and the mysql command line.
To find the path where my.cnf or my.ini is picked up, issue a command
mysql --help
It will echo out a lot of info. Search thru the text to find a line like the following:
Default options are read from the following files in the given order:
C:\WINDOWS\my.ini C:\WINDOWS\my.cnf C:\my.ini C:\my.cnf C:\Program Files\MySQL\MySQL Server 5.7\my.ini C:\Program Files\MySQL\MySQL Server 5.7\my.cnf
or
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
It is buried right in the middle of the echo output.
Lastly,
$ sudo netstat -tlpn | grep mysql
tcp6 0 0 :::3306 :::* LISTEN 10954/mysqld
port 3306.
If you have a few daemons running, you will get multiple lines. You use the -P (uppercase) switch at the cmd line for the port number. Note that lowercase -p is for the password (either prompt for it or give it)
I have CentOS 6.4 with NGINX.
When I try to start/stop/restart mysql server (/etc/init.d/mysqld restart) I get this error:
MySQL server PID file could not be found! [FAILED]
Starting MySQL..The server quit without updating PID file ([FAILED]/mysql/mysqld.pid).
What can I do to solve this problem?
Thanks!
I got the same error on a CentOS 6.3 where I upgraded MySQL to 5.6.14 but I kept the old my.cnf file. After upgrade, MySQL did not start anymore, giving me the same error as you described.
The problem was that I had this setting in my.cnf:
table_cache=2048
According to this link table_cache renamed table_open_cache..
"Seem like in 5.5 the system variable table_cache was renamed
table_open_cache..
In 5.6 mysqld fails if it finds an unknown variable
this means that upgrades from versions earlier than 5.5 can have
problems if table_cache is specified in my.cnf."
After I changed the above line to
table_open_cache=2048
MySQL started perfectly.
So, in the case you have MySQL 5.5+ (and maybe an older my.cnf), I suggest you to do the following:
remove my.cnf from /etc folder and try to start MySQL
if MySQL starts, the the problem is in my.cnf. Comment/uncomment all the settings one by one in order to see which is causing the problem.
Hope this helps.
I upgraded my Mac OS to 10.9.3 and encountered the above problem on mysql.server restart
The following fixed my problem
sudo chmod -R o+rwx /usr/local/var/mysql/
sudo chown -R mysql /usr/local/var/mysql/
sudo mysql.server restart
First of all make sure that which folder/file is not exist in /var/run/mysqld/mysqld.pid
if dir not exists then create it as:
sudo mkdir -p /var/run/mysqld/
if mysqld.pid is not exists then create it as:
sudo touch /var/run/mysqld/mysqld.pid
change ownership as:
sudo chown mysql:mysql -R /var/run/mysqld
chmod 775 -R /var/run/mysqld
restart mysql service
sudo service mysql restart
I find that sometimes MySQL processes are still running. Certainly this was the case on my OS X Yosemite system so use the following command to find any processes that show up with MySQL in the name:
ps aux | grep mysql
Then kill them using the command
sudo kill -9 PID, replacing PID with the offending process ID.
Check if there is a lock.
/etc/init.d/mysql status
If the OS says that there is a lock, something like:
ERROR! MySQL is not running, but lock file (/var/lock/subsys/mysql) exists
remove that lock file and restart.
I found this worked....
# ps aux | grep mysql

Please I need Help, Thanks.
i've resolved the issue in this way:
sudo chmod -R 777 /opt/lampp
sudo chown -hR nobody /opt/lampp
sudo chmod -R 755 /opt/lampp
then stop other mysqld running with:
sudo service mysql stop
Also had this issue, after troubleshooting for almost 2 hours I found that it was because of other Apache and MySQL packages also running on my system. Removed all Apache and MySQL packages and reinstalled XAMPP again. Success.
