mysql5.7.13 環(huán)境搭建教程(解壓縮版)_MySQL

最近決定學習數據庫,在比較了各個數據庫之后,選擇從mysql入手,主要原因:
??開源
??成熟,通用
??用戶量多,社區(qū)完善
??入門簡單

一、下載安裝
?mysql的官網下載地址:http://dev.mysql.com/downloads/mysql/
?mysql官網有倆種版本可供下載,分別是客戶端版本(Recommended Download,也是官網的推薦版本)和解壓縮版本(Archive)。我這里選擇的是解壓縮版本,點擊download進行下載,下載完畢后直接將壓縮包解壓到您想要安裝mysql的目標路徑即可。
我下載的是5.7.13版本,解壓后,得到一個mysql-5.7.13-winx64的文件夾,它包含如下文件:
2016/07/18? 14:34???

????????? .
2016/07/18? 14:34??? ????????? ..
2016/07/18? 14:34??? ????????? bin
2016/05/25? 13:50??????????? 17,987 COPYING
2016/07/18? 14:34??? ????????? docs
2016/07/18? 14:33??? ????????? include
2016/07/18? 14:34??? ????????? lib
2016/05/25? 14:08???????????? 1,141 my-default.ini
2016/05/25? 13:50???????????? 2,478 README
2016/07/18? 14:34??? ????????? share
?????????????? 3 個文件???????? 21,606 字節(jié)
?????????????? 7 個目錄 118,994,726,912 可用字節(jié)
至此,下載安裝完畢?

二、配置mysql?

1.配置my.ini
我這里將mysql-5.7.13-winx64文件重命名為mysql(原文件名太長了),該文件下的my-default.ini是默認的配置文件,我們這里需要自己重新實現配置:將my-default.ini復制一份并重命名為my.ini,并將最將basedir、datadir等參數的文件目錄替換成你自己mysql所在目錄的路徑。

  # 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 = C:mysql datadir = C:mysqldata # port = ..... # 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   

我這里的mysql文件放在c盤下,所以只要把上面文件中“c:/mysql”的地方填入你自己的文件路徑就ok了。?

2.配置環(huán)境變量
將你的mysql bin文件夾的路徑添加到PATH中,很簡單,不多說了。

三、運行mysql
以管理員身份運行cmd(一定要用管理員身份運行),并進入到mysql的bin文件中
mysqld –remove
mysqld –install
mysqld –initialize //會生成一個data文件夾
net start mysql //啟動mysql服務
依次執(zhí)行這三個命令后,打開data文件夾,找到其下error文件類型的文件打開,該文件是本次mysql初始化的log日志,包括初始化密碼。如果顯示“root@localhost is created with an empty password !”,則為空。然后執(zhí)行
?mysql -uroot -p
輸入用戶名和密碼,顯示“ Type ‘help;’ or ‘h’ for help. Type ‘c’ to clear the current input statement. ”,則表示連接成功。?

四、登錄出錯
?
如果登錄的時候存在問題,顯示“ Access denied for user ‘root’@’localhost’”,可以嘗試重新設置設置root密碼:
?1.修改/my.ini文件,在[mysqld]下添加 skip-grant-tables , 再啟動mysql

?2.然后用空密碼方式使用root用戶登錄 MySQL;
?mysql -u root

?3.修改root用戶的密碼;

  mysql> update mysql.user set password=PASSWORD('新密碼') where User='root' mysql> flush privileges; mysql> quit 

?4.重新啟動MySQL,就可以使用新密碼登錄了。
