MYSQL-8.0.11-WINX64(免安裝版)配置

OS value auth IE alter ransac 不支持 caching 安裝服務
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.初始化數據庫
在MySQL安裝目錄的 bin 目錄下執行命令:
mysqld --initialize --console
執行完成後,會打印 root 用戶的初始默認密碼,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,後續登錄需要用到。
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,用什麽方法,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插件
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,填入即可登錄成功,進入MySQL命令模式。
之前,MySQL的密碼認證插件是“mysql_native_password”,而現在使用的是“caching_sha2_password”。
因為當前有很多數據庫工具和鏈接包都不支持“caching_sha2_password”,為了方便,我暫時還是改回了“mysql_native_password”認證插件。
在MySQL中執行命令:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
修改密碼驗證插件,同時修改密碼。
如果想默認使用“mysql_native_password”插件認證,可以在配置文件中配置default_authentication_plugin
項。
[mysqld]
default_authentication_plugin=mysql_native_password
