MySQL5.6+windows2008怎么没有my.ini配置文件

Posted 2023-05-08

是有的my.ini配置一些服务参数的，必须有这个文件：
查找路径：安装路径\\mysql\\MySQL Server 5.6\\my.ini
my.ini配置内容：

# MySQL Server Instance Configuration File
# ----------------------------------------------------------------------
# Generated by the MySQL Server Instance Configuration Wizard
#
#
# Installation Instructions
# ----------------------------------------------------------------------
#
# On Linux you can copy this file to /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options
# (@localstatedir@ for this installation) or to
# ~/.my.cnf to set user-specific options.
#
# On Windows you should keep this file in the installation directory
# of your server (e.g. C:\\Program Files\\MySQL\\MySQL Server 4.1). To
# make sure the server reads the config file use the startup option
# "--defaults-file".
#
# To run run the server from the command line, execute this in a
# command line shell, e.g.
# mysqld --defaults-file="C:\\Program Files\\MySQL\\MySQL Server 4.1\\my.ini"
#
# To install the server as a Windows service manually, execute this in a
# command line shell, e.g.
# mysqld --install MySQL41 --defaults-file="C:\\Program Files\\MySQL\\MySQL Server 4.1\\my.ini"
#
# And then execute this in a command line shell to start the server, e.g.
# net start MySQL41
#
#
# Guildlines for editing this file
# ----------------------------------------------------------------------
#
# In this file, you can use all long options that the program supports.
# If you want to know the options a program supports, start the program
# with the "--help" option.
#
# More detailed information about the individual options can also be
# found in the manual.
#
#
# CLIENT SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by MySQL client applications.
# Note that only client applications shipped by MySQL are guaranteed
# to read this section. If you want your own MySQL client program to
# honor these values, you need to specify it as an option during the
# MySQL client library initialization.
#
[client]

port=3306

[mysql]

default-character-set=gbk

# SERVER SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by the MySQL Server. Make sure that
# you have installed the server correctly (see above) so it reads this
# file.
#
[mysqld]

# The TCP/IP Port the MySQL Server will listen on
port=3306

#Path to installation directory. All paths are usually resolved relative to this.
basedir="D:/MySQL Server 5.0/"

#Path to the database root
datadir="D:/MySQL Server 5.0/Data/"

# The default character set that will be used when a new schema or table is
# created and no character set is defined
default-character-set=gbk

# The default storage engine that will be used when create new tables when
default-storage-engine=INNODB

# Set the SQL mode to strict
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

# The maximum amount of concurrent sessions the MySQL server will
# allow. One of these connections will be reserved for a user with
# SUPER privileges to allow the administrator to login even if the
# connection limit has been reached.
max_connections=100

# Query cache is used to cache SELECT results and later return them
# without actual executing the same query once again. Having the query
# cache enabled may result in significant speed improvements, if your
# have a lot of identical queries and rarely changing tables. See the
# "Qcache_lowmem_prunes" status variable to check if the current value
# is high enough for your load.
# Note: In case your tables change very often or if your queries are
# textually different every time, the query cache may result in a
# slowdown instead of a performance improvement.
query_cache_size=14M

# The number of open tables for all threads. Increasing this value
# increases the number of file descriptors that mysqld requires.
# Therefore you have to make sure to set the amount of open files
# allowed to at least 4096 in the variable "open-files-limit" in
# section [mysqld_safe]
table_cache=256

# Maximum size for internal (in-memory) temporary tables. If a table
# grows larger than this value, it is automatically converted to disk
# based table This limitation is for a single table. There can be many
# of them.
tmp_table_size=17M

# How many threads we should keep in a cache for reuse. When a client
# disconnects, the client\'s threads are put in the cache if there aren\'t
# more than thread_cache_size threads from before. This greatly reduces
# the amount of thread creations needed if you have a lot of new
# connections. (Normally this doesn\'t give a notable performance
# improvement if you have a good thread implementation.)
thread_cache_size=8

#*** MyISAM Specific options

# The maximum size of the temporary file MySQL is allowed to use while
# recreating the index (during REPAIR, ALTER TABLE or LOAD DATA INFILE.
# If the file-size would be bigger than this, the index will be created
# through the key cache (which is slower).
myisam_max_sort_file_size=100G

# If the temporary file used for fast index creation would be bigger
# than using the key cache by the amount specified here, then prefer the
# key cache method. This is mainly used to force long character keys in
# large tables to use the slower key cache method to create the index.
myisam_max_extra_sort_file_size=100G

# If the temporary file used for fast index creation would be bigger
# than using the key cache by the amount specified here, then prefer the
# key cache method. This is mainly used to force long character keys in
# large tables to use the slower key cache method to create the index.
myisam_sort_buffer_size=33M

# Size of the Key Buffer, used to cache index blocks for MyISAM tables.
# Do not set it larger than 30% of your available memory, as some memory
# is also required by the OS to cache rows. Even if you\'re not using
# MyISAM tables, you should still set it to 8-64M as it will also be
# used for internal temporary disk tables.
key_buffer_size=22M

# Size of the buffer used for doing full table scans of MyISAM tables.
# Allocated per thread, if a full scan is needed.
read_buffer_size=64K
read_rnd_buffer_size=256K

# This buffer is allocated when MySQL needs to rebuild the index in
# REPAIR, OPTIMZE, ALTER table statements as well as in LOAD DATA INFILE
# into an empty table. It is allocated per thread so be careful with
# large settings.
sort_buffer_size=256K 参考技术A include int main() char string[10];int i; for(i=0;i..

mysql忘记密码怎么办？

Windows:
1. 用系统管理员登陆系统。
2. 停止MySQL的服务。
3. 进入命令窗口(cmd)，然后进入MySQL的安装目录，比如我的安装目录是c:\mysql,进入C:\mysql\bin
4. 跳过权限检查启动MySQL，
c:\mysql\bin>mysqld-nt --skip-grant-tables
5. 重新打开一个cmd窗口，进入c:\mysql\bin目录，设置root的新密码
c:\mysql\bin>mysqladmin -u root flush-privileges password "newpassword"
c:\mysql\bin>mysqladmin -u root -p shutdown
将newpassword替换为你要用的root的密码，第二个命令会提示你输入新密码，重复第一个命令输入的密码。
6. 停止MySQL Server，用正常模式启动Mysql
7．你可以用新的密码链接到Mysql了。

Unix&Linux：
1.用root或者运行mysqld的用户登录系统；
2．利用kill命令结束掉mysqld的进程；
3．使用--skip-grant-tables参数启动MySQL Server
shell>mysqld_safe --skip-grant-tables &
4.为[email protected]设置新密码
shell>;mysqladmin -u root flush-privileges password "newpassword"
．重启MySQL Server

kill -9 mysql进程
mysqld_safe --user=mysql --skip-grants-table
