mysql 5.7.22 winx32 解压缩版安装步骤 mysql 5.7.22 winx32 解压缩版的安装实践步骤阅读详情

1、官网下载对应版本，下载地址为https://dev.mysql.com/downloads/mysql/5.7.html#downloads，我下载的文件为“mysql-5.7.22-winx64.zip”；

2、考虑到数据库容量会增加，建议解压缩到可用容量较大的盘符，我解压缩到D盘；

3、进入解压缩目录，新建my.ini文件，内容如下：

[mysqld]
# set basedir to your installation path
basedir=D:/mysql-5.7.22-winx64
# set datadir to the location of your data directory
datadir=D:/mysql-5.7.22-winx64/data

4、使用cmd进入解压缩目录下的bin/目录下

# 安装mysql服务，安装完成后，可在右键“计算机”-“管理”-“服务”中看到，默认服务名为“MySQL”，也可以在install后面指定服务名称
D:\mysql-5.7.22-winx64\bin>mysqld install
Service successfully installed.

# 初始化data目录
D:\mysql-5.7.22-winx64\bin>mysqld.exe --initialize

初始化后会在datadir路径下生成一个*.err的文件，打开如下：

2018-05-27T04:49:08.182952Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2018-05-27T04:49:11.016957Z 0 [Warning] InnoDB: New log files created, LSN=45790
2018-05-27T04:49:11.546958Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2018-05-27T04:49:11.676958Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 4c70979b-6169-11e8-9db4-00ff13a6d817.
2018-05-27T04:49:11.676958Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.
2018-05-27T04:49:11.696958Z 1 [Note] A temporary password is generated for root@localhost: q&10*I#<fi-w

最后一行“A temporary password is generated for root@localhost: q&10*I#<fi-w”冒号后面的就是临时密码；

# 启动MySQL服务
D:\mysql-5.7.22-winx64\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。

5、修改密码

后面有两种方式可以修改密码，一种是使用刚才生成的临时密码登录修改，另一种是修改配置文件跳过密码登录然后修改密码；

5.1 通过临时密码登录

# 使用临时密码登录
E:\mysql-5.7.22-winx64\bin>mysql -u root -p
Enter password: ************

# 查看端口号
mysql> show global variables like 'port';

# 通过ALTER语句修改密码
mysql> ALTER user 'root'@'localhost' identified by 'Jiubugaosuni_01';
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW GLOBAL VARIABLES LIKE 'port';
+---------------+-------+
| Variable_name | Value |

5.2 跳过密码登录

datadir=D:/mysql-5.7.22-winx64/data
skip-grant-tables

5.2.2 无密码登录

# 而应该使用如下命令，设置临时密码
