1. 解壓zip包到安裝目錄
首先，將mysql-8.0.11-winx64.zip 解壓縮到 安裝D:/mysql-8.0.11-winx64 目錄下，
2.配置文件
在安裝根目錄下添加 my.ini
基本配置文件（my）
[mysqld]
basedir = D:\mysql-8.0.11-winx64
datadir = D:\mysql-8.0.11-winx64\data
port = 3306
lower_case_table_names = 2
default_authentication_plugin=mysql_native_password
參考 基本配置：
[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 # 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 = D:\Program\MySQL
datadir = D:\DBs\MySQL
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
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
character-set-server = utf8mb4
performance_schema_max_table_instances = 600
table_definition_cache = 400
table_open_cache = 256
[mysql]
default-character-set = utf8mb4
[client]
default-character-set = utf8mb4
3.初始化數(shù)據(jù)庫(kù)
在MySQL安裝目錄的 bin 目錄下執(zhí)行命令：
mysqld --initialize --console
執(zhí)行完成后，會(huì)打印 root 用戶的初始默認(rèn)密碼，比如：
2018-04-20T02:35:01.507037Z 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:\Program\MySQL8\bin\mysqld.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:\Program\MySQL\share\english\errmsg.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: APWCY5wshjQ
2018-04-20T02:35:07.017280Z 0 [System] [MY-013170] [Server] D:\Program\MySQL8\bin\mysqld.exe (mysqld 8.0.11) initializing of server has completed
其中，第4行的“APWCY5wshjQ”就是初始密碼，在沒(méi)有更改密碼前，需要記住這個(gè)密碼，后續(xù)登錄需要用到。
如果沒(méi)記住，那也沒(méi)事，刪掉初始化的 datadir 目錄，再執(zhí)行一遍初始化命令，又會(huì)重新生成的。當(dāng)然，也可以使用安全工具，強(qiáng)制改密碼，用什么方法，自己隨意。
4.安裝服務(wù)
在MySQL安裝目錄的 bin 目錄下執(zhí)行命令：
mysqld --install [服務(wù)名]
4.啟動(dòng)服務(wù)
net start MySQL
更改密碼和密碼認(rèn)證插件
在MySQL安裝目錄的 bin 目錄下執(zhí)行命令：
mysql -uroot -p
這時(shí)候會(huì)提示輸入密碼，記住了第3步的密碼，填入即可登錄成功，進(jìn)入MySQL命令模式。
之前，MySQL的密碼認(rèn)證插件是“mysql_native_password”，而現(xiàn)在使用的是“caching_sha2_password”。
因?yàn)楫?dāng)前有很多數(shù)據(jù)庫(kù)工具和鏈接包都不支持“caching_sha2_password”，為了方便，我暫時(shí)還是改回了“mysql_native_password”認(rèn)證插件。
在MySQL中執(zhí)行命令：
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
修改密碼驗(yàn)證插件，同時(shí)修改密碼。
如果想默認(rèn)使用“mysql_native_password”插件認(rèn)證，可以在配置文件中配置default_authentication_plugin項(xiàng)。
[mysqld]
default_authentication_plugin=mysql_native_password
總結(jié)
