環境:Windows 7 XAMPP 1.7.3#2006 - MySQL的恢復轉儲時MySQL服務器已消失

我已經經歷了這個問題,改變的設定文件

my.ini許多計算器解決了

現在看起來像

# 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 @[email protected]) 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] 
#user  = your_username 
#password = your_password

# 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.

# Replication Master Server (default) 
# binary logging is required for replication

# required unique id between 1 and 2^32 - 1 
# 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   = mysql-bin 

# Point the following paths to different dedicated disks 
tmpdir   = "D:/Program Files/xampp/tmp/" 
#log-update  = "D:/Program Files/xampp/tmp/mysql" 

# Uncomment the following if you are using InnoDB tables 
#skip-innodb 
innodb_data_home_dir   = "D:/Program Files/xampp/mysql/data/" 
innodb_data_file_path   = ibdata1:10M:autoextend 
innodb_log_group_home_dir  = "D:/Program Files/xampp/mysql/data/" 
# You can set .._buffer_pool_size up to 50 - 80 % 
# of RAM but beware of setting memory usage too high 
innodb_buffer_pool_size   = 16M 
innodb_additional_mem_pool_size = 2M 
# Set .._log_file_size to 25 % of buffer pool size 
innodb_log_file_size   = 5M 
innodb_log_buffer_size   = 8M 
innodb_flush_log_at_trx_commit = 1

[mysqldump]

max_allowed_packet = 254M 

[mysql]

# Remove the next comment character if you are not familiar with SQL 
#safe-updates 

[isamchk] 
key_buffer = 20M 
sort_buffer_size = 20M 
read_buffer = 2M 
write_buffer = 2M 

[myisamchk] 
key_buffer = 20M 
sort_buffer_size = 20M 
read_buffer = 2M 
write_buffer = 2M 

[mysqlhotcopy] 
interactive-timeout 

但我仍然得到同樣的錯誤。我正在嘗試恢復大小爲160MB的mysqldump,其中有許多BLOB內容。

你製作後重新啓動MySQL服務改變? –

嘗試改變max_allowed_packet設置服務器中的較大值的解釋。

打開位於您的MySQL安裝文件夾中的「my.ini/cnf」,並在[mysqld]部分更改「max_allowed_packet = 64M」,並且不要忘記重新啓動服務器。

SHOW VARIABLES LIKE 'max_allowed_packet';
