Configurar o limite de conexão

[alexandremanowar 0]

E ae pessoalEu estou com um problema de conexão no mysql que é o seguinte, o mysql esta funcionando legal e eu tenho o apache conectando no mysql com php que também esta funcionando normal, aí eu precisei instalar o tomcat para usar jsp e fiz o código de conexão que estas ok porém ele da uma mensagem de conexão negada, aí procurei na net e descobri que eu tenho que aumentar o limite de conexão. Como eu faço isso ? estou usando linuxAbrigado

Verifique no arquivo de configuração (deve ser o my.cnf no linux) se há este item: max_conections, geralmente está em 100.

Posta a mensagem de erro completa ae p/ nós.

E ae amigo beleza.

Então eu abri o arquivo e não existe essa linha max_conections como eu faço para configurar ela?

A mensagem de erro que o meu código exibe esse msn de erro:

Olha o meu arquivo my.cnf:

# 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>

Como eu faço para configurar o max_conections?

Cara fiz igual você colocou mas não deu certo! Vou fazer alguns testes no mysql que tenho no windows para ver se passa se passar o problema é no mysql mesmo.Valeu pela ajuda assim que eu terminar os teste eu informo se funcionou at+

Galera, obrigado a quem tentou me ajudar, como suspeitei o problema era no mysql um amigo me informou como deveria ser a configuração do mysql no arquivo my.cnf tem uma opção skip-network essa opção desativa a conexão com os host foi só comentar ela que tudo ficou ok.

Obrigado a todos que me ajudaram
