上一次安装完成Mysql5.6服务，一段时间后发生异常，Mysql服务无法启动进程终止： 1067；网上找了好多方法还是没能解决这个问题，今天重新安装Mysql5.6，同样出现这个问题，后来通过阅读

MySQL 5.6 Reference Manual Including MySQL Cluster NDB 7.3 Reference Guide

这个问题最终得以解决了。

下面是安装Mysql On Windows 解压安装方式。

下载Mysql安装包：mysql-5.6.12-win32.zip；
解压安装到D:\__dev下；
添加环境变量，创建MYSQL_HOME变量，

1

MYSQL_HOME=D:\__dev\mysql-5.6.12-win32

配置Path路径，、bin

1

%MYSQL_HOME%\bin;
修改mysql-5.6.12-win32下的my-default.ini文件

#Path to installation directory. All paths are usually resolved relative to this.

#basedir="C:/Program Files/MySQL/MySQL Server 5.0/"

basedir = D:/__dev/mysql-5.6.12-win32

#Path to the database root

#datadir="C:/Program Files/MySQL/MySQL Server 5.0/Data/"

datadir = D:/__dev/mysql-5.6.12-win32/data

如上图配置basedir和datadir.

在开发指南上有精简配置如下图：

mysql5.6 1067问题

5. 使用管理员权限运行命令窗口，切换工作目录为Path目录下，安装Mysql服务

mysqld -install

出现Service successfully installed.

表示安装服务成功

6. 启动mysql服务

1	`net start mysql`

7.登录到mysql，并修改root用户密码，默认为空

1 2	`mysql>mysq -uroot` `mysql>update mysql.user` `set` `password=PASSWORD('root') where User='root'`

问题解决了，mysql5.6的配置文件在安装目录下，名字已经变为my-default.ini.

# 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=0

# 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

# div [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=15M

# 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=30M

# 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

#*** INNODB Specific options ***

# Use this option if you have a MySQL server with InnoDB support enabled

# but you do not plan to use it. This will save memory and disk space

# and speed up some things.

#skip-innodb

# Additional memory pool that is used by InnoDB to store metadata

# information. If InnoDB requires more memory for this purpose it will

# start to allocate it from the OS. As this is fast enough on most

# recent operating systems, you normally do not need to change this

# value. SHOW INNODB STATUS will display the current amount used.

innodb_additional_mem_pool_size=2M

# If set to 1, InnoDB will flush (fsync) the transaction logs to the

# disk at each commit, which offers full ACID behavior. If you are

# willing to compromise this safety, and you are running small

# transactions, you may set this to 0 or 2 to reduce disk I/O to the

# logs. Value 0 means that the log is only written to the log file and

# the log file flushed to disk approximately once per second. Value 2

# means the log is written to the log file at each commit, but the log

# file is only flushed to disk approximately once per second.

innodb_flush_log_at_trx_commit=1

# The size of the buffer InnoDB uses for buffering log data. As soon as

# it is full, InnoDB will have to flush it to disk. As it is flushed

# once per second anyway, it does not make sense to have it very large

# (even with long transactions).

innodb_log_buffer_size=1M

# InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and

# row data. The bigger you set this the less disk I/O is needed to

# access data in tables. On a dedicated database server you may set this

# parameter up to 80% of the machine physical memory size. Do not set it

# too large, though, because competition of the physical memory may

# cause paging in the operating system. Note that on 32bit systems you

# might be limited to 2-3.5G of user level memory per process, so do not

# set it too high.

innodb_buffer_pool_size=40M

# Size of each log file in a log group. You should set the combined size

# of log files to about 25%-100% of your buffer pool size to avoid

# unneeded buffer pool flush activity on log file overwrite. However,

# note that a larger logfile size will increase the time needed for the

# recovery process.

innodb_log_file_size=20M

# Number of threads allowed inside the InnoDB kernel. The optimal value

# depends highly on the application, hardware as well as the OS

# scheduler properties. A too high value may lead to thread thrashing.

innodb_thread_concurrency=8

log-error=D:/__dev/mysql-5.6.12-win32/err.log
