MySql 8.0.11-Winxp64(免安裝版)配置教程
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.配置檔案
在安裝根目錄下新增 my.ini
基本配置檔案（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.初始化資料庫
在MySQL安裝目錄的 bin 目錄下執行命令：
mysqld --initialize --console
執行完成後，會列印 root 使用者的初始預設密碼，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: APWCY5ws&hjQ 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“APWCY5ws&hjQ”就是初始密碼，在沒有更改密碼前，需要記住這個密碼，後續登入需要用到。
如果沒記住，那也沒事，刪掉初始化的 datadir 目錄，再執行一遍初始化命令，又會重新生成的。當然，也可以使用安全工具，強制改密碼，用什麼方法，自己隨意。
4.安裝服務
在MySQL安裝目錄的 bin 目錄下執行命令：
mysqld --install [服務名]
4.啟動服務
net start MySQL
更改密碼和密碼認證外掛
在MySQL安裝目錄的 bin 目錄下執行命令：
mysql -uroot -p
這時候會提示輸入密碼，記住了第3步的密碼，填入即可登入成功，進入MySQL命令模式。
之前，MySQL的密碼認證外掛是“mysql_native_password”，而現在使用的是“caching_sha2_password”。
因為當前有很多資料庫工具和連結包都不支援“caching_sha2_password”，為了方便，我暫時還是改回了“mysql_native_password”認證外掛。
在MySQL中執行命令：
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
修改密碼驗證外掛，同時修改密碼。
如果想預設使用“mysql_native_password”外掛認證，可以在配置檔案中配置default_authentication_plugin項。
[mysqld] default_authentication_plugin=mysql_native_password
