mysql5.7通过文件zip方式安装-九五小庞
为什么通过zip的方式进行安装
电脑上已安装过mysql数据库，想要再安装一个。
1.下载mysql安装包
直接找到mysql官网，在官网上下载zip安装包。
https://downloads.mysql.com/archives/community/
解压完成后是这个样子的(注意：解压完的文件放到一个合适的地方，不要乱放)
2.在mysql-5.7.38-winx64安装包中创建my.ini文件，创建data文件夹
[mysql] # 设置mysql客户端默认字符集 default-character-set=utf8 [mysqld] #skip-grant-tables #设置3310端口 port = 3310 #关闭ONLY_FULL_GROUP_BY sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION' # 设置mysql的安装目录 basedir=G:\Program Files\mysql-5.7.37-winx64 # 设置mysql数据库的数据的存放目录 datadir=G:\Program Files\mysql-5.7.37-winx64\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
3.初始化mysql数据库
以管理员身份打开命令行
切换到mysql安装包的目录下
执行 mysqld --initialize初始化, 然后发现data文件夹多了mysql的文件夹,也就意味着数据库正常生成了
4.安装服务
在mysql安装包目录下创建bat文件
@set mysql_service="G:\Program Files\mysql-5.7.37-winx64\bin\mysqld.exe" ::设置服务名 @set service_name="MYSQL57" ::安装服务 %mysql_service% --install %service_name% --defaults-file="G:\Program Files\mysql-5.7.37-winx64\my.ini" pause
然后以管理员身份运行【安装.bat】
安装成功后，在电脑服务中会有一个MYSQL57服务（注意，如果服务没有启动，需要手动启动一下服务）
5.修改root管理员密码和权限
修改my.ini文件，在[mysqld]节点中加上 skip-grant-tables参数
说明:skip-grant-tables参数的作用是，通过root用户登录数据库，不需要输入密码，直接绕过密码
改完配置后，记得需要重启一下mysql57服务
连接上mysql数据库，进行修改

修改root用户的链接访问权限
