Ahoj, mám LAMP řešení. Pokouším se přistoupit k MySQL serveru (localhost) v Céčku. Při připojení přes prohlížeč (
http://localhost/phpmyadmin) vše funguje jak má. V programu ale dojde k chybě
2002: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)Vlezl jsem do /opt/lampp/etc/my.cnf a socket přesměroval do /tmp/mysql.sock. Po restartu serveru přestalo fungovat webové rozhraní
#2002 - The server is not responding (or the local MySQL server's socket is not correctly configured)
Connection for controluser as defined in your configuration failed.
a program podal následující výpis:

//vím, ten kod je prasarna, teprve zkousim jak na to

# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /opt/lampp/var/mysql) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients
[client]
#password = pass
port = 3306
#socket = /opt/lampp/var/mysql/mysql.sock

# Replication Master Server (default)

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <hostname>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <pass>
#
# The port the master is listening on.
