各位用户为了找寻关于MySql 8.0.11-Winxp64(免安装版)配置教程的资料费劲了很多周折。这里教程网为您整理了关于MySql 8.0.11-Winxp64(免安装版)配置教程的相关资料,仅供查阅,以下为您介绍关于MySql 8.0.11-Winxp64(免安装版)配置教程的详细内容
1. 解压zip包到安装目录
首先,将mysql-8.0.11-winx64.zip 解压缩到 安装D:/mysql-8.0.11-winx64 目录下,
2.配置文件
在安装根目录下添加 my.ini
基本配置文件(my)
? 1 2 3 4 5 6[mysqld]
basedir = D:mysql-8.0.11-winx64
datadir = D:mysql-8.0.11-winx64data
port = 3306
lower_case_table_names = 2
default_authentication_plugin=mysql_native_password
参考 基本配置:
? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27[mysqld]
# 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 #

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 = D:ProgramMySQL
datadir = D:DBsMySQL
port = 3306
# 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

3.初始化数据库
在MySQL安装目录的 bin 目录下执行命令:
mysqld --initialize --console
执行完成后,会打印 root 用户的初始默认密码,比如:
? 1 2 3 4 52018-04-20T02:35:01.507037Z 0 [Warning] [MY-010915] [Server]
'NO_ZERO_DATE'
,
'NO_ZERO_IN_DATE'
and
'ERROR_FOR_DIVISION_BY_ZERO'
sql modes should be used
with
strict mode. They will be merged
with
strict mode
in
a future release.
2018-04-20T02:35:01.507640Z 0 [System] [MY-013169] [Server] D:ProgramMySQL8binmysqld.exe (mysqld 8.0.11) initializing
of
server
in
progress
as
process 11064
2018-04-20T02:35:01.508173Z 0 [ERROR] [MY-010340] [Server] Error message file
'D:ProgramMySQLshareenglisherrmsg.sys'
had
only
1090 error messages, but it should contain
at
least 4512 error messages.
Check
that the above file
is
the
right
version
for
this program!
2018-04-20T02:35:05.464644Z 5 [Note] [MY-010454] [Server] A
temporary
password
is
generated
for
root@localhost: APWCY5ws&hjQ
2018-04-20T02:35:07.017280Z 0 [System] [MY-013170] [Server] D:ProgramMySQL8binmysqld.exe (mysqld 8.0.11) initializing
of
server has completed
其中,第4行的“APWCY5ws&hjQ”就是初始密码,在没有更改密码前,需要记住这个密码,后续登录需要用到。
如果没记住,那也没事,删掉初始化的 datadir 目录,再执行一遍初始化命令,又会重新生成的。当然,也可以使用安全工具,强制改密码,用什么方法,自己随意。
4.安装服务
在MySQL安装目录的 bin 目录下执行命令:
mysqld --install [服务名]
4.启动服务
net start MySQL
更改密码和密码认证插件
在MySQL安装目录的 bin 目录下执行命令:
mysql -uroot -p
这时候会提示输入密码,记住了第3步的密码,填入即可登录成功,进入MySQL命令模式。
之前,MySQL的密码认证插件是“mysql_native_password”,而现在使用的是“caching_sha2_password”。
因为当前有很多数据库工具和链接包都不支持“caching_sha2_password”,为了方便,我暂时还是改回了“mysql_native_password”认证插件。
在MySQL中执行命令:
? 1ALTER
USER
'root'
@
'localhost'
IDENTIFIED
WITH
mysql_native_password
BY
'password'
;
修改密码验证插件,同时修改密码。
如果想默认使用“mysql_native_password”插件认证,可以在配置文件中配置default_authentication_plugin项。
? 1 2[mysqld]
default_authentication_plugin=mysql_native_password
