mysql5.7通過文件zip方式安裝-九五小龐
為什麼通過zip的方式進行安裝
電腦上已安裝過mysql資料庫，想要再安裝一個。
1.下載mysql安裝包
直接找到mysql官網，在官網上下載zip安裝包。
//downloads.mysql.com/archives/community/
解壓完成後是這個樣子的(注意：解壓完的文件放到一個合適的地方，不要亂放)
2.在mysql-5.7.38-winx64安裝包中創建my.ini文件，創建data文件夾
[mysql] # 設置mysql客戶端默認字符集 default-character-set=utf8 [mysqld] #skip-grant-tables #設置3310埠 port = 3310 #關閉ONLY_FULL_GROUP_BY sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION' # 設置mysql的安裝目錄 basedir=G:\Program Files\mysql-5.7.37-winx64 # 設置mysql資料庫的數據的存放目錄 datadir=G:\Program Files\mysql-5.7.37-winx64\data # 允許最大連接數 max_connections=200 # 服務端使用的字符集默認為8比特編碼的latin1字符集 character-set-server=utf8 # 創建新表時將使用的默認存儲引擎 default-storage-engine=INNODB
3.初始化mysql資料庫
以管理員身份打開命令行
切換到mysql安裝包的目錄下
執行 mysqld --initialize初始化, 然後發現data文件夾多了mysql的文件夾,也就意味著資料庫正常生成了
4.安裝服務
在mysql安裝包目錄下創建bat文件
@set mysql_service="G:\Program Files\mysql-5.7.37-winx64\bin\mysqld.exe" ::設置服務名 @set service_name="MYSQL57" ::安裝服務 %mysql_service% --install %service_name% --defaults-file="G:\Program Files\mysql-5.7.37-winx64\my.ini" pause
然後以管理員身份運行【安裝.bat】
安裝成功後，在電腦服務中會有一個MYSQL57服務（注意，如果服務沒有啟動，需要手動啟動一下服務）
5.修改root管理員密碼和許可權
修改my.ini文件，在[mysqld]節點中加上 skip-grant-tables參數
說明:skip-grant-tables參數的作用是，通過root用戶登錄資料庫，不需要輸入密碼，直接繞過密碼
改完配置後，記得需要重啟一下mysql57服務
連接上mysql資料庫，進行修改

修改root用戶的鏈接訪問許可權
