阿新 • • 發佈：2019-07-22
後端的人員都會用到資料庫，一大部分人喜歡用mysql，因為mysql是開源的，那麼mysql怎麼安裝呢？如果不注意安裝不成功，很有可能導致刪除不乾淨再一次也很難安裝成功，這篇文章小猿圈加加詳細介紹一下，mysql的安裝過程，大家一起來看看吧。
1、下載MySQL 8.0.16，地址：官網下載
2、解壓到你自己的磁碟
3. 配置Path路徑：系統屬性 => 高階 => 高階 => 系統變數 => path後新增 (如：D:\Tools\mysql-8.0.16-winx64\bin)
4. 在mysql根目錄下新建 my.ini，此檔案是初始化資訊（預設mysql根目錄不存此檔案）：
# 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 = D:\Tools\mysql-8.0.16-winx64 datadir = D:\Tools\mysql-8.0.16-winx64\data 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
5. 系統管理員模式執行cmd 輸入如下命令
C:\WINDOWS\system32>d: //進入d盤 D:\>cd "Tools\mysql-8.0.16-winx64\bin" //進入mysql bin檔案下 D:\Tools\mysql-8.0.16-winx64\bin>mysqld --install //執行安裝mysql服務程序 Service successfully installed. //提示服務安裝成功 D:\Tools\mysql-8.0.16-winx64\bin>mysqld --initialize --console //根據配置檔案初始化mysql，注意檢視輸出的日誌中有臨時密碼， C_:qVsvG6Hxa 就是登入的臨時密碼 A temporary password is generated for root@localhost: C_:qVsvG6Hxa D:\Tools\mysql-8.0.16-winx64\bin>net start mysql //啟動mysql服務 D:\Tools\mysql-8.0.16-winx64\bin>mysql -uroot -p //登入mysql Enter password: //這裡輸入上面的臨時密碼 mysql> alter user root@localhost identified by '123456'; //修改密碼，123456是當前root賬號登陸的密碼 mysql> flush privileges; // 刷新系統表 應用上面修改的新密碼
到處安裝完成！
只要按著上面的步驟走，一般是不會導致mysql會安裝失敗的，一定要一步一步來，這樣防止mysql安裝不成功，後面會很麻煩的，這篇文章就到這了，希望看到這篇文章的朋友們能順利安裝成功，安裝完畢之後，咱們就可以通過命令對資料庫進行增、刪、改、查了，下一篇文章小猿圈加加會詳細寫，可以先去小猿圈預習一下
