當一臺計算機安裝多個MySQL的時候就需要一些下面的配置
mysqld --install [服務名] //這裡可以設定服務名
重新解釋一下安裝的操作各個含義
D:\Program Files\mysql-8.0.11>cd bin //切換到bin目錄下 D:\Program Files\mysql-8.0.11\bin>mysqld --remove //我以前安裝過mysql，先移除 Service successfully removed. D:\Program Files\mysql-8.0.11\bin>mysqld --install //安裝mysql，注意這裡都是兩個小橫線 Service successfully installed. D:\Program Files\mysql-8.0.11\bin>mysqld --install mysql5.6//這裡可以設定服務名 設定服務名在一個機器安裝多個MySQL服務時可以用到,建議服務名全部用小寫,否則服務無法啟動 D:\Program Files\mysql-8.0.11\bin>mysqld --initialize --console //注意這裡會生成一個密碼 //在mysql5.6版本時,此步驟不能要,否則服務無法啟動, 2018-05-17T07:59:00.988023Z 0 [System] [MY-013169] [Server] D:\Program Files\mysql-8.0.11\bin\mysqld.exe (mysqld 8.0.11) initializing of server in progress as process 3556 2018-05-17T07:59:25.239288Z 5 [Note] [MY-010454] [Server] A temporary password is generated for[email protected]host: 3<?*Yfr3>gdw //這裡3<?*Yfr3>gdw就是隨機生成的密碼 2018-05-17T07:59:45.170784Z 0 [System] [MY-013170] [Server] D:\Program Files\mysql-8.0.11\bin\mysqld.exe (mysqld 8.0.11) initializing of server has completed D:\Program Files\mysql-8.0.11\bin>net start mysql //啟動mysql服務 MySQL 服務正在啟動 ..

在安裝了mysql 8.0.11之後又安裝了mysql 5.6,現在我們再裝一個MySQL 5.7
記錄一下過程
首先去官網下載 ----> 解壓 配置環境變數 ------> 然後新建data資料夾---->新建my.ini
注意修改一下埠 我的修改成如下的樣子
[mysql] # 設定mysql客戶端預設字符集 default-character-set=utf8 [mysqld] #設定3308埠,由於以前使用了3306和3307了,現在使用3308 port = 3308 # 設定mysql的安裝目錄，根據自己目錄修改 basedir=D:\Program Files\mysql-5.7.23 # 設定mysql資料庫的資料的存放目錄 datadir=D:\Program Files\mysql-5.7.23\data # 允許最大連線數 max_connections=1000 # 服務端使用的字符集預設為8位元編碼的latin1字符集 character-set-server=utf8 # 建立新表時將使用的預設儲存引擎 default-storage-engine=INNODB ###下面的這些配置我沒用#### #忘記密碼時使用 #skip-grant-tables #設定協議認證方式 #default_authentication_plugin=mysql_native_password
然後就是一通安裝服務 初始化資料庫
D:\Program Files\mysql-5.7.23\bin>net stop mysql5.6
mysql5.6 服務正在停止..
mysql5.6 服務已成功停止。
D:\Program Files\mysql-5.7.23\bin>mysqld --install mysql5.7
Service successfully installed.
D:\Program Files\mysql-5.7.23\bin>mysqld --initialize --console

D:\Program Files\mysql-5.7.23\bin>net start mysql5.7
mysql5.7 服務正在啟動 .
mysql5.7 服務已經啟動成功。
D:\Program Files\mysql-5.7.23\bin>mysql -h localhost -P3308 -uroot -p
Enter password: ************
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)發現無法連線!!!
找了一會原因,發現服務有問題
發現5.6和5.7的路徑竟然是一樣的,果斷刪除服務
D:\Program Files\mysql-5.7.23\bin>net stop mysql5.7
mysql5.7 服務正在停止.
mysql5.7 服務已成功停止。
D:\Program Files\mysql-5.7.23\bin>mysqld --remove mysql5.7
Service successfully removed.修改環境變數
path中將5.7的環境變數移到前面,
然後以管理身份重新開啟一個命令視窗！！！
安裝服務
C:\windows\system32>D:
D:\>cd D:\Program Files\mysql-5.7.23\bin
D:\Program Files\mysql-5.7.23\bin>mysqld --install mysql5.7
Service successfully installed.檢視服務正常
刪除5.7路徑下data目錄中的所有內容（不刪除直接啟動服務也是可以的）
C:\windows\system32>D:
D:\>cd D:\Program Files\mysql-5.7.23\bin
D:\Program Files\mysql-5.7.23\bin>mysqld --install mysql5.7
Service successfully installed.
//初始化資料庫，如果沒有刪除data資料夾可以不用初始化，直接啟動服務即可
D:\Program Files\mysql-5.7.23\bin>mysqld --initialize --console

//啟動服務
D:\Program Files\mysql-5.7.23\bin>net start mysql5.7
mysql5.7 服務正在啟動 .
mysql5.7 服務已經啟動成功。
//指定埠連結資料庫
D:\Program Files\mysql-5.7.23\bin>mysql -h localhost -P3308 -uroot -p
Enter password: ************ //這裡是密碼，部落格中解釋過了，如果沒有重新初始化就是上一個密碼

//修改密碼，兩步，還有一個重新整理許可權
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)至此，資料庫安裝完成。
效果，三個版本的資料庫都啟動成功，各自佔用不同的埠
