[mysql]

# 设置mysql的安装目录

Other configuration items are set according to their own needs, which are not explained here.
Fourth, configure the service and start
1. Run cmd as an administrator, and enter the bin directory under the decompression directory
2. Install mysql service
|
1
|
mysqld
install
|
3. Initialization:
|
1
|
mysqld --initialize
|
4. Turn on the service
net start mysql
5. Find the initial password
mysq在5.7版本以上为root用户默认生成了一个临时登录密码，该密码是生成在数据目录下的.err文件里的；在my.ini配置文件里我写的数据目录是：
|
1
|
datadir=D:
/db/mysqldata
|
所以找到该文件：
上面圈出的部分即为登录密码。
如果没有该文件，请用错误的密码尝试登录一次mysql
|
1
|
mysql -uroot -p<br>输入一个错误密码后再回来查看有没有sheng.err文件
|
6.修改初始密码
首先用默认初始密码登录root
|
1
|
mysql -uroot -p<br>输入默认密码
|
修改密码：
mysql> set password for 用户名@localhost = password('新密码');
mysql> set password for root@localhost = password('123456');
显示Ok后密码修改成功。
如果提示缺少.dll报错：
无法定位程序输入点fegetound于动态链接库MSVCR120.dll上
安装MYSQL途中提示 无法定位程序输入点fegetound于动态链接库MSVCR120.dll上 查看本地C:windos下 system32跟64都有这个MSVCR120.dll文件，从网上或者360上搜到微软运行库合计，然后安装安装完运行库后，问题解决。
