he problem happened on lampp, but i can not handle it to work right, please help me,thank you.

after download lampp 1.5.3，the following steps were carried out:

Code: Select all

root@BioInfoServ:/home/biowee# /opt/lampp/lampp start
Starting XAMPP for Linux 1.5.3...
XAMPP: Starting Apache with SSL (and PHP5)...
XAMPP: Another MySQL daemon is already running.
XAMPP: Starting ProFTPD...
XAMPP for Linux started.


then,the services were checked out

Code: Select all

root@BioInfoServ:/home/biowee# ps -ef | grep mysqld
root     17396     1  0 17:07 pts/1    00:00:00 /bin/sh /opt/lampp/bin/mysqld_safe --datadir=/opt/lampp/var/mysql --pid-file=/opt/lampp/var/run/mysqld.pid
mysql    17468 17396  0 17:07 pts/1    00:00:00 /opt/lampp/sbin/mysqld --basedir=/opt/lampp --datadir=/opt/lampp/var/mysql --user=mysql --pid-file=/opt/lampp/var/run/mysqld.pid --skip-locking --port=3306 --socket=/opt/lampp/var/run/mysqld.sock
root     18549     1  0 17:35 ?        00:00:02 gedit file:///opt/lampp/var/run/mysqld.pid
root     23096 17194  0 20:01 pts/1    00:00:00 grep mysqld


but, when browsing from http://localhost, the status looked like this

Code: Select all

so, i had to restart lampp:

Code: Select all

root@BioInfoServ:/home/biowee# /opt/lampp/lampp start
Starting XAMPP for Linux 1.5.3...
XAMPP: Starting Apache with SSL (and PHP5)...
XAMPP: Another MySQL daemon is already running.
XAMPP: Starting ProFTPD...
XAMPP for Linux started.


but, it's so mazing: 'XAMPP: Another MySQL daemon is already running." and phpmyqdmin didn't worked well:

Code: Select all

welcome to phpMyAdmin 2.8.1
MySQL said:
#2002 - Can't connect to local MySQL server through socket '/opt/lampp/var/mysql/mysql.sock'


my.cnf looked like this:

Code: Select all

[client]
#password   = your_password
port      = 3306
socket      = /opt/lampp/var/run/mysqld.sock
[mysqld_safe]
socket      = /opt/lampp/var/run/mysqld.sock
nice      = 0

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
port      = 3306
socket      = /opt/lampp/var/run/mysqld.sock
user      = mysql
pid-file   = /opt/lampp/var/run/mysqld.pid
basedir      = /opt/lampp
datadir      = /opt/lampp/var/mysql
tmpdir      = /opt/lampp/tmp


i have chmod /opt/lampp as nobody:nogroup, now what and how to do?

See the difference:

mysql 17468 17396 0 17:07 pts/1 00:00:00 /opt/lampp/sbin/mysqld --basedir=/opt/lampp --datadir=/opt/lampp/var/mysql --user=mysql --pid-file=/opt/lampp/var/run/mysqld.pid --skip-locking --port=3306 --socket=/opt/lampp/var/run/mysqld.sock

#2002 - Can't connect to local MySQL server through socket '/opt/lampp/var/mysql/mysql.sock'

Code: Select all

welcome to phpMyAdmin 2.8.1
MySQL said:
#2002 - Can't connect to local MySQL server through socket '/opt/lampp/var/mysql/mysql.sock'


should be

Code: Select all

#2002 - the server is not responding (or the local MySQL server's socket is not correctly configured


[/code]

so it's not the diffrent from "mysql.sock" and "mysqld.sock", and the other wrong configures?

2002 - Can't connect to local MySQL server through socket '/opt/lampp/var/mysql/mysql.sock'

should be

#2002 - the server is not responding (or the local MySQL server's socket is not correctly configured

Then your first post was a lie or you have changed something?

when i posted it, i copied it from wrong page on website,. my second post was the real error log. That is to say "#2002 - the server is not responding (or the local MySQL server's socket is not correctly configured" is the real information that i got from phpmyadmin.

so how to handle the problem?

i have edited "/opt/lampp/var/run/mysql.sock" into my.cnf, php.ini and config.inc.php.

my.cnf:

Code: Select all


[client]
#password   = your_password
port      = 3306
socket      = /opt/lampp/var/run/mysql.sock
[mysqld_safe]
socket      = /opt/lampp/var/run/mysql.sock
nice      = 0

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
port      = 3306
socket      = /opt/lampp/var/run/mysql.sock
user      = mysql
pid-file   = /opt/lampp/var/run/mysql.pid
basedir      = /opt/lampp
datadir      = /opt/lampp/var/mysql
tmpdir      = /opt/lampp/tmp


php.ini:

Code: Select all

mysql.default_socket ="/opt/lampp/var/run/mysql.sock"


config.inc.php

Code: Select all

$cfg['Servers'][$i]['host']          = 'localhost'; // MySQL hostname or IP address
$cfg['Servers'][$i]['port']          = '';          // MySQL port - leave blank for default port
$cfg['Servers'][$i]['socket']        = '/opt/lampp/var/run/mysql.sock';   


but when i restart lampp, the proble is still here[

i have edited "/opt/lampp/var/run/mysql.sock" into my.cnf, php.ini and config.inc.php.

What does

Code: Select all

ps -ef | grep mysqld

tell you now?

it told me like this:

Code: Select all

root@BioInfoServ:/home/biowee# cd /
root@BioInfoServ:/# ps -ef | grep mysqld
root     17396     1  0 Aug09 pts/1    00:00:00 /bin/sh /opt/lampp/bin/mysqld_safe --datadir=/opt/lampp/var/mysql --pid-file=/opt/lampp/var/run/mysqld.pid
mysql    17468 17396  0 Aug09 pts/1    00:00:00 /opt/lampp/sbin/mysqld --basedir=/opt/lampp --datadir=/opt/lampp/var/mysql --user=mysql --pid-file=/opt/lampp/var/run/mysqld.pid --skip-locking --port=3306 --socket=/opt/lampp/var/run/mysqld.sock
root     31251 17194  0 00:31 pts/1    00:00:00 grep mysqld


and i wondered that when i restarted lampp, why it told me like this:

Code: Select all

...
XAMPP: Another MySQL daemon is already running.
...


i have edited "/opt/lampp/var/run/mysql.sock" into my.cnf, php.ini and config.inc.php.

it told me like this:

mysql 17468 17396 0 Aug09 pts/1 00:00:00 /opt/lampp/sbin/mysqld --basedir=/opt/lampp --datadir=/opt/lampp/var/mysql --user=mysql --pid-file=/opt/lampp/var/run/mysqld.pid --skip-locking --port=3306 --socket=/opt/lampp/var/run/mysqld.sock

You see, MySQL is allways using "/opt/lampp/var/run/mysqld.sock" and not "/opt/lampp/var/run/mysql.sock".

Better change all configs to "/opt/lampp/var/run/mysqld.sock"

let me try it again. but it can not work well, the proble still here

after edit "/opt/lampp/var/run/mysqld.sock" into my.cnf, php.ini and config.inc.php, and restart ampp:

Code: Select all

# /opt/lampp/lampp restart


if you find "XAMPP: Another MySQL daemon is already running. ", please stop mysql and lampp:

Code: Select all

# /opt/lampp/lampp mysqlstop
# /opt/lampp/lampp stop


then, test it as user=msql to activate mysql

Code: Select all

#/opt/lampp/sbin/mysqld --user=mysql


then check mysql service:

Code: Select all

#ps -ef | grep mysqld


it should tell us like this:

Code: Select all

mysql    12764     1  0 15:16 ?        00:00:00 /opt/lampp/sbin/mysqld --user=my sql
root     13065 12981  0 15:24 pts/1    00:00:00 grep mysqld


but, if you can not stop lampp, please reboot your system, then start mysql alone:

Code: Select all

# /opt/lampp/lampp startmysql
XAMPP: Starting MySQL...


if you retrived it as followings:

Code: Select all

root@BioInfoServ:/home/biowee# Warning: World-writable config file '/opt/lampp/etc/my.cnf' is ignored
Warning: World-writable config file '/opt/lampp/etc/my.cnf' is ignored
Warning: World-writable config file '/opt/lampp/etc/my.cnf' is ignored
Warning: World-writable config file '/opt/lampp/etc/my.cnf' is ignored


you would chmod my.cnf:

Code: Select all

chmod 644 /opt/lampp/etc/my.cnf


now resart your lampp, mysql is right there
