Server take 20s to connect

2005-11-23 Thread Luiz Rafael Culik Guimaraes

Dear Friends

I've set up an mysql server with version 4.1.15 by compiling the .src.rpm on 
an linux machine running conectiva linux 10 with 1.5Gb of RAM on an Pentiun 
4 2.88 Gz machine


The app I have  is running on windows connecting to this linux server by 
using direct ip address for mysql linux machine, but is taking more then 20s 
to connect.

also no firewall active on linux server

all tables are innodb

bellow the server config

# Example MySQL config file for very large systems.
#
# This is for a large system with memory of 1G-2G where the system runs 
mainly

# MySQL.
#
# 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 /var/lib/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 = your_password
port  = 3306
socket  = /var/lib/mysql/mysql.sock

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
port  = 3306
socket  = /var/lib/mysql/mysql.sock

key_buffer = 384M
max_allowed_packet = 1M

# Try number of CPU's*2 for thread_concurrency

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the enable-named-pipe option) will render mysqld useless!

# Replication Master Server (default)

# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id = 1

# 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 =   username
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   password
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port =  port
#
# binary logging - not required for slaves, but recommended
#log-bin

# Point the following paths to different dedicated disks
#tmpdir  = /tmp/
#log-update  = /path-to-dedicated-directory/hostname

# Uncomment the following if you are using BDB tables
#bdb_cache_size = 384M
#bdb_max_lock = 10

# Uncomment the following if you are using InnoDB tables
#innodb_data_home_dir = /var/lib/mysql/
#innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend
#innodb_log_group_home_dir = /var/lib/mysql/
#innodb_log_arch_dir = /var/lib/mysql/
# You can set .._buffer_pool_size up to 50 - 80 %

#innodb_buffer_pool_size = 384M
#innodb_additional_mem_pool_size = 20M

Hi Luiz,

.src.rpm on an linux machine running conectiva linux 10 with 1.5Gb of 
RAM on an Pentiun 4 2.88 Gz machine

Sounds like the machine where your MySQL server is running has a broken 
DNS configuration, or the machine that purports to provide reverse DNS 
mappings for your client machine is broken.


Try using the 'host' command to determine where the problem is.

Regards,

Jeremy
