mysql5.7版本windows的安装

mysql5.7版本windows的安装,

mysql-5.5.46-win32.msi；mysql-5.5.46-winx64.msi；mysql-5.7.12-winx64.msi

5.5的版本安装后自动调用初始化和序进行初始化工做（由MySQLInstanceConfig.exe完成）,不过5.7版本开始要进行自行初始化.

下面开始说5.7windows版本的安装.

1. 先正常安装,固然也能够自定义,选择好安装目录.我这里选择.D:\盘，安装好的路径为

“ D:\Program Files\MySQL\MySQL Server 5.7 ”

2. 而后copy一下 my-default.ini 复制一分为 my.ini 这个文件。

而后修改这个文件。

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[mysqld]
character-set-server=utf8 
collation-server=utf8_general_ci 

#init_connect='SET NAMES utf8'


# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M 

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 


[mysql]
default-character-set = utf8

[mysql.server]
default-character-set = utf8


[mysqld_safe]
default-character-set = utf8


[client]
default-character-set = utf8

主要有这些地方须要说明

# basedir = .....
# datadir = .....
# port = .....
这些是安装目录，数据目录，和程序端口。能够默认

另外一些主要是说字符编码的问题。在windows上mysql会利用系统默认的编码的GBK。

因此咱们要添加一些配置。

在 mysqld 标端下添加以下：

[mysqld]
character-set-server=utf8 
collation-server=utf8_general_ci 

#init_connect='SET NAMES utf8'

[mysql]
default-character-set = utf8

[mysql.server]
default-character-set = utf8


[mysqld_safe]
default-character-set = utf8


[client]
default-character-set = utf8

写好配置文件后，咱们就能够进行初始化了。

到安装好后的目录下的 \bin 执行

mysqld –initialize 能够进行这初始化。 这里也提供--defaults-file=file_name 这个来指定参数。

若是使用了 --defaults-file要把它放在第一个参数，另外一个参数是 --console .

生成的mysql的root用户密码在data目录下的.err日志文件里如图

再就是注册成服务。

mysqld --install mysql --defaults-file="D:\Program Files\MySQL\MySQL Server 5.7\my.ini"

这样就完成了.

咱们能够在windows系统的服务的mysql服务打开mysql服务。

mysql.exe -uroot -p 输入用户密码，会进入mysql中，可是没法使用，会要求咱们先改密码。

能够以使用以下命令：

set password=password("root");
flush privileges;

ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';

网上有人说5.7版本这个mysql数据的user表中没有password这个项了，不能使用，我亲测能够使用，我确实查看了下，user表中确实已经改成authentication_string了。

而后退出，从新使用新密码登录便可。

别忘了，show variables like '%character%';查看相关的字符类型。

为了确保不出理乱码最好使用utf8这种编码。

show variables like '%character%';

这样就OK了。

[mysql]
default-character-set = utf8


[mysql.server]
default-character-set = utf8


[mysqld_safe]

[client]

这样的话，初始化和服务安装都不用指定文件
