安装64位mysql5.626
计算机--右击属性--左上高级系统变量---环境变量 path 添加 mysql 的bin目录 ;D:\mysqlwinx64\bin
1 //mysql 5.6.26安装前先解压到d盘根目录 2 cd D:\mysqlwinx64\bin 3 mysqld --install //注册服务 5 net start mysql//启动服务 6 修改数据管理员密码 默认空密码 7 mysqladmin -u root password "root" 8 9 登录数据库 mysql -u root -p
发现空密码登录不上 改了密码好使了 后来重新打开cmd 又不好使干脆删掉这个服务 sc delete mysql
error 1045 (28000):access denied for user 'odbc'@'localhost'(using password:yes)
1、到mysql官网下载mysql-5.6.14-winx64.zip
2、将解压缩后的文件放到自己想要的地方，并配置环境变量。例如我存放的目录为：F:\mysql\mysql-5.6.14-winx64
在环境变量中添加：MYSQL_HOME:F:\mysql\mysql-5.6.14-winx64
在path路径中加入：%MYSQL_HOME%\bin
配置环境变量不是必须的，只是为了能更方便的在命令行中使用mysql的命令行工具。
3、修改ini配置文件
5.6.14的解压缩版里有一个my-default.ini文件，copy一份改名为my.ini放在同级目录下。修改my.ini，遵照第二篇文章的做法。我的my.ini内容如下：
# 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]
loose-default-character-set=utf8
basedir = F:/mysql/mysql-5.6.14-winx64
datadir = F:/mysql/mysql-5.6.14-winx64/data
[client]
loose-default-character-set=utf8
[WinMySQLadmin]
Server=F:/mysql/mysql-5.6.14-winx64/bin/mysqld.exe
# 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
# 设置mysql的安装目录
# 设置mysql数据库的数据存放目录
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
character-set-server=utf8
# 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
4、安装服务
进入cmd：
（这个好像要管理员权限，我在C盘下搜索cmd.exe --> C:\Windows\winsxs\wow64_microsoft-windows-commandprompt_31bf3856ad364e35_6.1.7601.17514_none_f387767e655cd5ab\cmd.exe，右键以管理员身份运行。这个cmd.exe是64位的cmd。因为我安装的是64位的mysql）
输入命令：
C:\>f:
F:\>cd F:\mysql\mysql-5.6.14-winx64\bin
F:\mysql\mysql-5.6.14-winx64\bin>mysqld -install
Service successfully installed.
5、启动服务
F:\mysql\mysql-5.6.14-winx64\bin>cd\
F:\>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
6、配置用户
还在上面的命令窗口里面，输入命令：mysql -u root -p
回车后提示输入密码。
mysql解压缩版初次安装管理员root的密码为空，因此直接再回车一次就登入mysql数据库了。
F:\>mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1

成功后
输入命令：use mysql; /*使用mysql数据库*/
mysql> use mysql
Database changed
输入命令：select host,user,password from user; /* 查看系统的账户信息 */
mysql> select host,user,password from user;
+-----------+------+----------+
| host | user | password |
+-----------+------+----------+
| localhost | root | |
| 127.0.0.1 | root | |
| ::1 | root | |
| localhost | | |
+-----------+------+----------+
4 rows in set (0.00 sec)
到这一步就可以了！！！
host：代表mysql服务允许哪个IP来的请求。localhost和127.0.0.1指mysql服务所在的主机，即本地。：：1是IPV6的IP地址写法，
全称为：0000:0000:0000:0000:0000:0000:0000:0001。现在都是IPV4的网络，可以不用管他。
user：指账户名称。不同的host下账户名称可以相同。
password：密码。
可以看到，默认账户里只支持本地连接，并且账户没有密码。现在的问题明确了，就是要将匿名用户删除，为root用户添加远程访问和密码，再为自己添加个人账户。指令如下：
mysql> update user set password=PASSWORD('root') where user='root';
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0
mysql> grant all on *.* to root@'%' identify by 'root';

mysql> grant all on *.* to walle@'%' identify by '123456' with grant option;

+-----------+------+-------------------------------------------+

| ::1 | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| localhost | | |

使用navicat 连接mysql管理员账户登陆后
还原库原理：
新建同名数据库
在我的文档目录找到navicat根目录
如：D:\Documents\Navicat\MySQL\servers\severs
下面就是数据库备份文件目录
新建scm数据库选择utf字符集 将之前备份的数据库包转移到 d盘我的文档目录下面 查看还原信息 右键还原文件 backinfo发现实在我的文档下面
然后解压数据库文件 选中新建的库 选择还原数据库
任务计划 是需要设置开机密码的
当前计划：
安装tomcat和jdk
部署项目文件
单服务器部署两套程序研究
