MySql 5.7.14 安裝教程詳解(解壓版)
Mysql 5.7.14 使用常見問題匯總(推薦)
1、解壓
2、在目錄D:\Program Files\mysql-5.7.14-winx64下復制my-default.ini,放在與其相同目錄下,名稱顯示為my.ini;
3、編輯my.ini
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html # *** 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. [client] default-character-set=utf8 [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 Files\mysql-5.7.14-winx64 datadir = D:\Program Files\mysql-5.7.14-winx64\data tmpdir = D:\Program Files\mysql-5.7.14-winx64\data socket = D:\Program Files\mysql-5.7.14-winx64\data\mysql.sock port = 3306 # server_id = ..... max_connections = 100 table_open_cache = 256 query_cache_size = 1M tmp_table_size = 32M thread_cache_size = 8 innodb_data_home_dir = D:\Program Files\mysql-5.7.14-winx64\data innodb_flush_log_at_trx_commit = 1 innodb_log_buffer_size = 128M innodb_buffer_pool_size = 128M innodb_log_file_size = 10M innodb_thread_concurrency = 16 innodb-autoextend-increment = 1000 # 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 join_buffer_size = 128M sort_buffer_size = 32M read_rnd_buffer_size = 32M max_allowed_packet = 32M explicit_defaults_for_timestamp = true sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
4、在解壓目錄D:\Program Files\mysql-5.7.14-winx64下新建data文件(不用在文件夾做其他操作)
5、以管理員身份進入cmd界面(必須是管理員)
6、切換至mysql解壓目錄\bin下,初始化data目錄
輸入命令:mysqld --initialize-insecure (生成無密碼的root用戶)
或:mysqld --initialize(生成帶隨機密碼的root用戶)
7、初始化完成後啟動mysql服務
輸入命令:net start mysql
8、開始使用mysql
輸入命令:mysql -u root -p
9、停止mysql服務
輸入命令:net stop mysql
10、忘記root密碼後如何登錄
101、 關閉正在運行的MySQL服務。
10.2、 打開DOS窗口,轉到mysql\bin目錄。
10.3、輸入mysqld --skip-grant-tables 回車。--skip-grant-tables 的意思是啟動MySQL服務的時候跳過權限表認證。
10.4、再開一個DOS窗口(因為剛才那個DOS窗口已經不能動了),轉到mysql\bin目錄。
10.5、輸入mysql回車,如果成功,將出現MySQL提示符 >。
10.6、連接權限數據庫: use mysql; 。
10.7、改密碼:update user set password=password("123") where user="root";(別忘了最後加分號) 。
10.8、刷新權限(必須步驟):flush privileges; 。
10.9、 退出 quit。
10.10、注銷系統,再進入,使用用戶名root和剛才設置的新密碼123登錄。
11、修改root用戶密碼
5.7版本以前:
update user set authentication_string =password( 'root') where user = 'root;
5.7版本以後:
update user set password=password( 'root') where user = 'root;
