mysql community server 5.7 win10 怎么安装

win10 下安装、配置、启动mysql

1、下载http://dev.mysql.com/downloads/mysql/

2、Community >MySQL Community Server

3、Other Downloads: >Windows (x86, 32-bit), ZIP Archive

5、解压mysql-5.7.11-winx64.zip，解压在 D:\soft\mysql-5.7.11-winx64\mysql-5.7.11-winx64

6、在D:\soft\mysql-5.7.11-winx64\mysql-5.7.11-winx64目录下新建my.ini 文件，设置代码如下：

[mysql]

# 设置mysql客户端默认字符集

default-character-set=utf8

[mysqld]

#设置3306端口

port = 3306

# 设置mysql的安装目录

basedir=D:\mysql

# 设置mysql数据库的数据的存放目录

datadir=D:\mysql\data

# 允许最大连接数

max_connections=200

# 服务端使用的字符集默认为8比特编码的latin1字符集

character-set-server=utf8

# 创建新表时将使用的默认存储引擎

default-storage-engine=INNODB

#log-error=D:\mysql\mysql_log_err.txt

#log=D:\mysql\mysql_log.txt

#log-bin=d:/log/mysql/mysql_log_bin

#log-slow-queries= D:\mysql\mysql_log_slow.txt

7、安装mysql服务，以管理员身份执行cmd，

C:\WINDOWS\system32>d:

D:\>cd D:\soft\mysql-5.7.11-winx64\mysql-5.7.11-winx64\bin

D:\soft\mysql-5.7.11-winx64\mysql-5.7.11-winx64\bin>mysqld install （卸载用mysqld -remove）

Service successfully installed.

D:\soft\mysql-5.7.11-winx64\mysql-5.7.11-winx64\bin>

8、启动服务 net start mysql 本地计算机上的服务启动后停止。某些服务在未由其他服务或程序使用时将自动停止。

转用旧版本 mysql D:\soft\mysql_5.6.24_winx64\mysql-5.6.24-winx64

启动，提示：Windows 无法启动MySQL服务（位于 本地计算机上）。错误1067：进程意外终止

Windows 管理>时间查看器>自动以视图 >摘要页事件 提示：

Can't find messagefile 'D:\ oft\mysql_5.6.24_winx64\mysql-5.6.24-winx64\share\errmsg.sys'

For more information, see Help and Support Center at http://www.mysql.com.

D:\soft\被识别成D:\ oft\

修改mysql文件存放位置 D:\mysql

设置配置文件my.ini文件：

[mysql]

# 设置mysql客户端默认字符集

default-character-set=utf8

[mysqld]

#设置3306端口

port = 3306

# 设置mysql的安装目录

basedir=D:\mysql

# 设置mysql数据库的数据的存放目录

datadir=D:\mysql\data

# 允许最大连接数

max_connections=200

# 服务端使用的字符集默认为8比特编码的latin1字符集

character-set-server=utf8

# 创建新表时将使用的默认存储引擎

default-storage-engine=INNODB

#log-error=D:\mysql\mysql_log_err.txt

#log=D:\mysql\mysql_log.txt

#log-bin=d:/log/mysql/mysql_log_bin

#log-slow-queries= D:\mysql\mysql_log_slow.txt

并把D:\mysql\my.ini文件复制到C:\Windows 下面，启动mysql成功

9、设置环境变量：D:\mysql\bin

10、设置密码，新安装的root是没有密码，mysql -u root 进入mysql，执行语句：set password = password('123456')设置密码

C:\Users\alex>mysql -u root
