在C:\ wamp \ bin \ mysql \ mysql5.1.30 \ my.ini中，我在[mysqldump]和[wampmysqld]中将max_allowed_pa​​cket设置为100M.我在my.ini中找不到wait_timeout变量. 任何解决此问题的方法吗?作为参考，我在下面给出了my.ini文件的内容.

In C:\wamp\bin\mysql\mysql5.1.30\my.ini , i set the max_allowed_packet to 100M in [mysqldump] and [wampmysqld]. I couldnt find wait_timeout variable in my.ini. Any way to fix this problem ?. For your reference, i have given below the contents of my.ini file.

# 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 C:\mysql\data) 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.

# 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=mysql-bin

推荐答案

我在Windows上使用XAMPP，但遇到了同样的问题. 我以为这是超时变量，但它是max_allowed_packet.

I'm using XAMPP on Windows and had the same problem. I thought it was the timeout variable but it was max_allowed_packet.

此问题已解决:

# note the change was made at this section
[mysqld] 
port= 3306
socket= "/xampp/mysql/mysql.sock"
basedir="/xampp/mysql" 
tmpdir="/xampp/tmp" 
datadir="/xampp/mysql/data"
skip-locking
key_buffer = 16M
# it was 1M by default
max_allowed_packet = 2M
table_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M

此配置文件位于«XAMPP安装目录，默认为 C:\XAMPP » \mysql\bin\my.ini.

This configuration file is located at «XAMPP install directory, this is C:\XAMPP by default»\mysql\bin\my.ini.
