首先要安装MySQL 数据库才可以继续安装图形工具SQLyog
第一步：下载解压包》》
MYSQL官网地址：https://dev.mysql.com/downloads/file/?id=479669
绿色安装 直接解压即可。
第二步》》环境变量配置
解压之后放入E盘，需在系统进行环境变量配置
==============================================================================
第三步》》mysql初始化配置
接下来连接和启动数据库操作：
3.1 创建初始化配置my.ini配置文件 存放根目录下面 复制下面文档(需修改路径)
[mysqld] # 设置3306端口 port=3306 # 设置mysql的安装目录 basedir=E:\mysql\mysql-8.0.12-winx64 # 切记此处一定要用双斜杠\，单斜杠我这里会出错。 # 设置mysql数据库的数据的存放目录 datadir=E:\mysql\mysql-8.0.12-winx64\Data # 此处同上 # 允许最大连接数 max_connections=200 # 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统 max_connect_errors=10 # 服务端使用的字符集默认为UTF8 character-set-server=utf8 # 创建新表时将使用的默认存储引擎 default-storage-engine=INNODB # 默认使用“mysql_native_password”插件认证 default_authentication_plugin=mysql_native_password [mysql] # 设置mysql客户端默认字符集 default-character-set=utf8 [client] # 设置mysql客户端连接服务端时默认使用的端口 port=3306 default-character-set=utf8
3.2 在c:Windowssystem32 找到cmd.exe 右键以系统管理员身份启动该程序
指令路径切换到bin目录下输入指令：
//生成临时密码
mysqld --initialize --console
示例：
E:mysqlmysql-8.0.12-winx64in>mysqld --initialize --console 2018-09-03T03:05:19.275614Z 0 [System] [MY-013169] [Server] E:mysqlmysql-8.0.12-winx64inmysqld.exe (mysqld 8.0.12) initializing of server in progress as process 7608 2018-09-03T03:05:37.017614Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: oZig3fdGSh<E 2018-09-03T03:05:50.090414Z 0 [System] [MY-013170] [Server] E:mysqlmysql-8.0.12-winx64inmysqld.exe (mysqld 8.0.12) initializing of server has completed
oZig3fdGSh<E 为系统随机生成的临时密码
3.3 安装mysql 服务
mysqld --install
示例:
E:mysqlmysql-8.0.12-winx64in>mysqld --install Service successfully installed.
3.4 启动mysql服务
net start mysql
示例:
E:mysqlmysql-8.0.12-winx64in>net start mysql MySQL 服务正在启动 .. MySQL 服务已经启动成功。
3.5 进入mysql 输入以下指令之后 需要输入临时密码
mysql -u root -p
示例:
E:mysqlmysql-8.0.12-winx64in>mysql -u root -p Enter password: ************ Welcome to the MySQL monitor. Commands end with ; or g. Your MySQL connection id is 8 Server version: 8.0.12 Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or 'h' for help. Type 'c' to clear the current input statement. mysql>
3.6 修改临时密码
修改密码为root
alter user user() identified by "root";
示例:
mysql> alter user user() identified by "root"; Query OK,0 rows affected (0.25 sec)
修改完密码 退出数据库操作
mysql> exit
Bye
3.7 验证密码
E:mysqlmysql-8.0.12-winx64in>mysql -u root -p Enter password: **** Welcome to the MySQL monitor. Commands end with ; or g. Your MySQL connection id is 10 Server version: 8.0.12 MySQL Community Server - GPL Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.

Type 'c' to clear the current input statement. mysql>
ok mysql安装完成了密码也修改成功了 命令行操作麻烦，推荐使用图形化工具SQLyog。
