Windows下安装配置免安装MySQL5.7服务器

 

 

Windows下安装配置免安装MySQL5.7服务器


1、下载、解压安装包

从MySQL官方网站上下载mysql-5.7.19-winx64.zip

下载完成后,把安装包解压到D:DevSoftwaremysql57目录下,会生成一个mysql-5.7.19-winx64目录。现在MySQL的目录就是D:DevSoftwaremysql57mysql-5.7.19-winx64

2、创建数据目录

在D:DevSoftwaremysql57下创建一个data目录,作为mysql服务器的数据目录。

3、创建配置文件

在D:DevSoftwaremysql57mysql-5.7.19-winx64创建一个my.ini文件,做为mysql的配置文件。

其内容为:

[mysqld]
basedir=D:/DevSoftware/mysql57/mysql-5.7.19-winx64
datadir=D:/DevSoftware/mysql57/data
port=3306

 现在MySQL安装目录中的结构是这样的:

D:DevSoftwaremysql57

                              |--mysql-5.7.19-winx64

                              |--data

                              |--mysql-5.7.19-winx64my.ini

这样MySQL软件的目录,数据目录data,和配置文件,就形成了这样一个结构。

4、添加mysql的bin目录到环境变量path中

把D:DevSoftwaremysql57mysql-5.7.19-winx64in目录添加到PATH环境变量中去。

5、把mysql服务器安装成windows服务

以管理员权限运行CMD,进入到D:DevSoftwaremysql57mysql-5.7.19-winx64in目录中,执行:

mysqld --install

就可以把mysql服务器注册成windows服务了。

D:DevSoftwaremysql57mysql-5.7.19-winx64in>mysqld --install
Service successfully installed.

6、初始化MySQL数据库

在CMD中,进入到mysql安装目录的bin下,执行

mysqld --initialize --console

就可以初始化数据库了。如果初始化过程中报错,一般是data目录下有文件,进入data目录,删除其中的文件,再次执行初始化语句,就可以成功了。

初始化完成后,初始化信息中会给出root用户的随机密码,记住这个密码,接下来登陆mysql服务器时,需要输入这个密码。

D:DevSoftwaremysql57mysql-5.7.19-winx64in>mysqld --initialize --console
2017-08-04T10:06:35.200271Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2017-08-04T10:06:36.851562Z 0 [Warning] InnoDB: New log files created, LSN=45790
2017-08-04T10:06:37.312575Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.

2017-08-04T10:06:37.691852Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.
2017-08-04T10:06:37.713805Z 1 [Note] A temporary password is generated for root@localhost: lwuW>7sxauEG

7、启动mysql服务器

因为mysql服务器已经被注册成Windows服务了,所以可以通过启动Windows服务的方式去启动mysql服务器。

在cmd中执行net start mysql。

D:DevSoftwaremysql57mysql-5.7.19-winx64in>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。

  

8、登陆mysql服务器,并修改root密码

启动mysql服务器之后,就可以登陆服务器了。登陆服务器的时候需要输入root密码,root的密码就是初始化数据库后,系统给出的随机密码。

登陆到服务器之后,不能执行其他语句,必须先修改root用户密码。具体信息,见下图:

D:DevSoftwaremysql57mysql-5.7.19-winx64in>mysql -uroot -p
Enter password: ************
Welcome to the MySQL monitor.  Commands end with ; or g.
Your MySQL connection id is 4
Server version: 5.7.19

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

mysql> show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql> set password=password('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)

修改root密码后,就可以在mysql中正常执行其他的命令了。可以试试看是否能执行sql命令。

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+
4 rows in set (0.00 sec)

mysql> create database test;
Query OK, 1 row affected (0.00 sec)

mysql> use test;
Database changed
mysql> create table a1(a int, b int);
Query OK, 0 rows affected (0.25 sec)

mysql> insert into a1 values(1,2), (3, 4), (5, 6);
Query OK, 3 rows affected (0.08 sec)
Records: 3  Duplicates: 0  Warnings: 0

mysql> select * from a1;
+------+------+
| a    | b    |
+------+------+
|    1 |    2 |
|    3 |    4 |
|    5 |    6 |
+------+------+
3 rows in set (0.00 sec)

mysql>

这样就装好了MySQL数据库。
