mysql安裝配置

1.首先到http://dev.mysql.com/ 上下載windows版，mysqlinstall,這個軟件mysql爲windows平臺提供安裝解決方案的軟件，。

2.複製mysql下的my-default.ini, 在同目錄下建立my.ini. my.ini爲mysql的配置。最簡單的配置：

1 basedir=D:/mysql-5.6.20-winx64
2 datadir=D:/mysql-5.6.20-winx64/data

base config

個人配置爲：

 1 # For advice on how to change settings please see
 2 # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
 3 # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
 4 # *** default location during install, and will be replaced if you
 5 # *** upgrade to a newer version of MySQL.
 6 
 7 [mysqld]
 8 character-set-server=utf8
 9 
10 # Remove leading # and set to the amount of RAM for the most important data
11 # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
12 # innodb_buffer_pool_size = 128M
13 
14 # Remove leading # to turn on a very important data integrity option: logging
15 # changes to the binary log between backups.
16 # log_bin
17 
18 # These are commonly set, remove the # and set as required.
19 # basedir = .....
20 # datadir = .....
21 # port = .....
22 # server_id = .....
23 basedir=D:/mysql-5.6.20-winx64
24 datadir=D:/mysql-5.6.20-winx64/data
25 port=3306
26 
27 character-set-server=utf8
28 default-storage-engine=INNODB
29 innodb_data_home_dir=D:/mysql-5.6.20-winx64/data
30 innodb_data_file_path=ibdata1:12M:autoextend
31 innodb_log_group_home_dir=D:/mysql-5.6.20-winx64/data
32 
33 innodb_buffer_pool_size=512M
34 # Remove leading # to set options mainly useful for reporting servers.
35 # The server defaults are faster for transactions and fast SELECTs.
36 # Adjust sizes as needed, experiment to find the optimal values.
37 # join_buffer_size = 128M
38 # sort_buffer_size = 2M
39 # read_rnd_buffer_size = 2M 
40 
41 # sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 

my.ini

3.設置環境變量PATH。將D:\mysql-5.6.20-winx64\bin加入path中。

4.CMD下面嘗試啓動mysqld,並將後臺log輸出在屏幕。

5.註冊mysql爲windows service. 之後能夠使用windows service來安裝mysqld和卸載mysqld的服務.

6.進入服務管理器

7.啓動MySQL服務

8.net start mysql 啓動mysql服務,net stop mysql 中止mysql服務

9.也能夠使用mysqladmin命令關閉mysql服務。

10.使用root用戶登陸mysql數據庫

11.show databases;顯示全部數據庫

12.修改root賬戶的登錄密碼1234：

13.建立數據庫須要指定中文編碼方式

14.查看MySQL存儲引擎

15.建立mysql遠程鏈接用戶，設置最大權限和登錄密碼。

還有一些測試mysql安裝的命令：

 

 

若是發生啓動錯誤的狀況，通常是my.ini沒有配置成功。

能夠查看根目錄下的*.err文件，針對具體狀況進行排查。

其中有一種狀況是將ib_logfile0，ib_logfile1刪除之後，重啓便可。
