#終于知道什么叫不會走先會跑了，剛開始接觸第一個case就是數據庫自動備份，我可是都沒安裝過啊？！?? 發完牢騷開始干活

首先，因為業務已經上線，不能隨便動，先搭建測試環境吧

規劃一下

版本：mysql-5.7.14-winx64.zip? 從官網下載

系統：windows 7?? 64bit

解壓縮到本地目錄?D:\app\mysql57 ?? #注意，非系統盤，非中文

將my-default.ini 復制一份重命名為my.ini? 添加如下內容，先保證能開啟服務

# 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.[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 = ..... # datadir = ..... # port = ..... # server_id = .....basedir="D:\app\mysql57"datadir="D:\app\mysql57\data" port=3306 max_connections=200 character-set-server=utf8 default-storage-engine=INNODB# 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 View Code

修改環境變量path，增加bin目錄


在命令行中cd到bin， 輸入mysqld -install MySQL --defaults-file="D:\app\mysql57\my.ini" 添加服務


在命令行中輸入初始化命令 .\mysqld.exe --initialize? 會生成data目錄，并且生成初始的root密碼 ，否則net start mysql 會無法開啟服務 #新版本特殊要求


之后服務可以開啟，從后綴為err的文件中取得密碼


復制默認密碼，使用默認密碼登錄mysql


必須使用命令先修改密碼，否則啥也不讓干


mysql> alter user 'root'@'localhost' identified by 'redhat';
Query OK, 0 rows affected (0.00 sec)
密碼修改成功，可以查詢數據庫了


安裝完成
