Mysql| Mysql5.6软件的安装

1.下载压缩软件

版本选择:
mysql 5.6 密码：wvsx

2.解压缩

将mysql软件解压到指定的位置.

3.设置环境变量和添加path

设置MySQL环境变量:
MYSQL_HOME:D:\ProgramFiles\mysql-5.6.27-winx64
添加MySQL安装路径到Path中:
;%MYSQL_HOME%\bin

PS: 环境变量设置主要是在Path中可以引用环境变量,Path是程序运行时默认的搜寻路径.

4.设置安装或卸载服务:(cmd最好以管理员身份运行)

指定mysql的配置文件来安装mysql服务:`mysqld install MySQL --defaults-file="D:\ProgramFiles\MySQL\mysql-5.6.27-winx64\my-default.ini"` 注：my-default.ini文件在MySQL解压后的根目录下，如果没有，可从其他地方中获取。

安装服务
mysqld -install

启动服务:
net start mysql

停止服务
net stop mysql

卸载服务
mysqld -remove

4.启动或停止MySQL

①通过mysql服务来启动mysql(前提是已经将mysql服务安装)
②直接运行mysql执行文件(如果是将mysql的安装路径添加到path中,可以直接通过命令行来启动mysql)

5. 修改 root 账号的密码

刚安装完成时root账号默认密码为空，此时可以将密码修改为指定的密码。如：123456
方法一：

c:>mysql –u rootmysql>show databases; mysql>use mysql;mysql>UPDATE user SET password=PASSWORD("123456") WHERE user='root';mysql>FLUSH PRIVILEGES;mysql>QUIT

方法二：
利用第三方管理工具进行密码修改。如Navicat for MySQL.

安装可能出现的问题:

问题1:错误信息:ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)问题1解决办法:主要是删除了my-int配置文件.重新启动mysql.  注意:初始密码是空  而不是root

有关MySQL目录的操作:

• 1.查看Mysql的安装目录:select @@basedir
