Windows下面安装和配置MySQL(5.6.20)

1.首先到http://dev.mysql.com/ 上下载windows版mysql5.6免安装zip包。然后将zip包解压到D:\mysql-5.6.20-winx64下。

2.复制mysql下的my-default.ini, 在同目录下创建my.ini. my.ini为mysql的配置。最简单的配置：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[mysqld]
character-set-server=utf8

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
basedir=D:/mysql-5.6.20-winx64
datadir=D:/mysql-5.6.20-winx64/data
port=13306

character-set-server=utf8
default-storage-engine=INNODB
innodb_data_home_dir=D:/mysql-5.6.20-winx64/data
innodb_data_file_path=ibdata1:12M:autoextend
innodb_log_group_home_dir=D:/mysql-5.6.20-winx64/data

innodb_buffer_pool_size=10240M
innodb_log_file_size=4G
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

# sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

my.ini
还可以在my.ini中增加lower_case_table_names=1(默认linux是区分表名大小写的，加上这句话表示在linux下不区分表名大小写)

mysql : Lock wait timeout exceeded; try restarting transaction

原因是你使用的InnoDB表类型的时候,
默认参数:innodb_lock_wait_timeout设置锁等待的时间是50s,
因为有的锁等待超过了这个时间,所以抱错.你可以把这个时间加长,或者优化存储过程,事务避免过长时间的等待.

#innodb_lock_wait_timeout = 50
innodb_lock_wait_timeout = 500 改成500秒

3.设置环境变量PATH。将[b]D:\mysql-5.6.20-winx64\bin[/b]加入path中。





4.CMD下面尝试启动mysqld --console,并将后台log输出在屏幕。



5.注册mysql为windows service. 以后可以使用windows service来安装mysqld和卸载mysqld的服务.

安装MySQL服务,一定要进入[b]D:\mysql-5.6.20-winx64\bin目录执行安装[/b]

mysqld install

卸载MySQL服务

mysqld remove

6.进入服务管理器



7.启动MySQL服务



8.net start mysql 启动mysql服务,net stop mysql 停止mysql服务



9.也可以使用mysqladmin命令关闭mysql服务。



10.使用root用户登录mysql数据库



如果MySQL的连接端口不是默认的3306，可以使用下面的命令

mysql -P13306 -u root -p

指定MySQL连接端口13306

如果MySQL的连接服务器IP不是本机或者用户名不支持本机登陆，可以使用下面的命令

mysql -h机器名或IP地址 -P13306 -u root -p

11.显示数据库文件存放路径和所有数据库

show global variables like "%datadir%"; --查看数据库文件存放路径
show databases;  --显示所有数据库

12.修改root帐户的登陆密码1234：

GRANT ALL ON *.* TO 'root'@'localhost' IDENTIFIED BY '1234';

\q 退出MySQL

13.创建数据库需要指定中文编码方式



14.查看MySQL存储引擎

show engines;

15.创建mysql远程连接用户，设置最大权限和登陆密码。

GRANT ALL ON *.* TO 'sa'@'%' IDENTIFIED BY '1234' WITH GRANT OPTION;

还有一些测试mysql安装的命令：







最后设置打开死锁开关的命令:

set global innodb_print_all_deadlocks=on

查看开关是否已经打开的命令：

show variables like 'innodb_print_all_deadlocks'

[b]skip-grant-tables：非常有用的mysql启动参数[/b]

在my.cnf文件中增加一行：

skip-grant-tables

或者以命令行参数启动mysql：

/usr/bin/mysqld_safe --skip-grant-tables &

登陆mysql

mysql

修改管理员密码：

use mysql;
update user set password=password('1234') where user='root';
flush privileges;
exit;

重启mysql
