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：

1 basedir=D:/mysql-5.6.20-winx64 2 datadir=D:/mysql-5.6.20-winx64/data base config

我的配置为：

1 # For advice on how to change settings please see 2 # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html 3 # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the 4 # *** default location during install, and will be replaced if you 5 # *** upgrade to a newer version of MySQL. 6 7 [mysqld] 8 character-set-server=utf8 9 10 # Remove leading # and set to the amount of RAM for the most important data 11 # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. 12 # innodb_buffer_pool_size = 128M 13 14 # Remove leading # to turn on a very important data integrity option: logging 15 # changes to the binary log between backups. 16 # log_bin 17 18 # These are commonly set, remove the # and set as required. 19 # basedir = ..... 20 # datadir = ..... 21 # port = ..... 22 # server_id = ..... 23 basedir=D:/mysql-5.6.20-winx64 24 datadir=D:/mysql-5.6.20-winx64/data 25 port=13306 26 27 character-set-server=utf8 28 default-storage-engine=INNODB 29 innodb_data_home_dir=D:/mysql-5.6.20-winx64/data 30 innodb_data_file_path=ibdata1:12M:autoextend 31 innodb_log_group_home_dir=D:/mysql-5.6.20-winx64/data 32 33 innodb_buffer_pool_size=10240M 34 innodb_log_file_size=4G 35 # Remove leading # to set options mainly useful for reporting servers. 36 # The server defaults are faster for transactions and fast SELECTs. 37 # Adjust sizes as needed, experiment to find the optimal values. 38 # join_buffer_size = 128M 39 # sort_buffer_size = 2M 40 # read_rnd_buffer_size = 2M 41 42 # 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D:\mysql-5.6.20-winx64\bin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D:\mysql-5.6.20-winx64\bin目录执行安装

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 "
