安裝

雙擊下載好的dmg文件，會彈出pkg彈框，再雙擊pkg圖標，進入安裝界面，在安裝界面上一路繼續，就安裝成功了。

環境變量

第一步，在終端切換到根目錄，編輯./.bash_profile文件

?  ~ cd ~ ?  ~ vim ./.bash_profile

第二步，進入vim編輯環境，按下i進入insert模式，輸入

export PATH=$PATH:/usr/local/mysql/bin export PATH=$PATH:/usr/local/mysql/support-files

第三步，按下 esc 退出 insert 模式，輸入 :wq 保存配置文件

:wq

第四步，在終端界面輸入以下命令，讓配置文件的修改生效，并查看環境變量是否設置成功

?  ~ echo $PATH /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin ?  ~ source ~/.bash_profile  ?  ~ echo $PATH             /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/mysql/bin:/usr/local/mysql/support-files ?  ~

MYSQL服務的啟停和狀態的查看

查看MYSQL的服務狀態

?  ~ sudo mysql.server status Password:  ERROR! MySQL is not running

啟動MYSQL服務

?  ~ sudo mysql.server start  Starting MySQL .Logging to '/usr/local/mysql/data/mj.local.err'.  SUCCESS!

停止MYSQL服務

?  ~ sudo mysql.server stop   Shutting down MySQL . SUCCESS!

重啟MYSQL服務

?  ~ sudo mysql.server restart  ERROR! MySQL server PID file could not be found! Starting MySQL . SUCCESS!

啟動

第一步，終端界面下輸入

?  ~ sudo mysql.server start  Starting MySQL .Logging to '/usr/local/mysql/data/mj.local.err'.  SUCCESS!

第二步，啟動MYSQL服務，啟動成功后繼續輸入

?  ~ mysql -u root -p

第三步，直接回車，進入數據庫，看到以下歡迎界面

Enter password:  Welcome to the MySQL monitor.  Commands end with ; or g. Your MySQL connection id is 1 Server version: 5.6.41 MySQL Community Server (GPL)  Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.  Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners.  Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.  mysql>

備注：默認安裝成功后沒有初始密碼，所以密碼不用輸入，直接回車即可。

初始化設置

設置初始密碼，進入mysql數據庫之后執行下面的語句，設置當前root用戶的密碼為root

?  ~ mysql -u root -p Enter password:  Welcome to the MySQL monitor.  Commands end with ; or g. Your MySQL connection id is 2 Server version: 5.6.41 MySQL Community Server (GPL)  Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.  Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners.  Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.  mysql> set password = password('root'); Query OK, 0 rows affected (0.01 sec)  mysql>

退出MYSQL的界面

mysql> exit Bye ?  ~

配置

進入到 /usr/local/mysql/support-files目錄，里面有個文件my-default.cnf

?  ~ cd /usr/local/mysql/support-files ?  support-files ll total 64 -rwxr-xr-x  1 root  wheel   1.1K  6 15  2018 binary-configure -rw-r--r--  1 root  wheel   773B  6 15  2018 magic -rw-r--r--  1 root  wheel   1.1K  6 15  2018 my-default.cnf -rwxr-xr-x  1 root  wheel   894B  6 15  2018 mysql-log-rotate -rwxr-xr-x  1 root  wheel    10K  6 15  2018 mysql.server -rwxr-xr-x  1 root  wheel   1.0K  6 15  2018 mysqld_multi.server ?  support-files

將目錄下的my-default.cnf文件復制到桌面上，改名為my.cnf，

?  support-files ll total 64 -rwxr-xr-x  1 root  wheel   1.1K  6 15  2018 binary-configure -rw-r--r--  1 root  wheel   773B  6 15  2018 magic -rw-r--r--  1 root  wheel   1.1K  6 15  2018 my-default.cnf -rwxr-xr-x  1 root  wheel   894B  6 15  2018 mysql-log-rotate -rwxr-xr-x  1 root  wheel    10K  6 15  2018 mysql.server -rwxr-xr-x  1 root  wheel   1.0K  6 15  2018 mysqld_multi.server ?  support-files cp my-default.cnf /Users/a1/Desktop/my.cnf

將內容替換為下面的內容

[mysqld] default-storage-engine=INNODB character-set-server=utf8 port = 3306  [client] default-character-set=utf8

將修改后的my.cnf文件復制到/etc目錄下，重啟MYSQL

?  /etc cp /Users/a1/Desktop/my.cnf ./ cp: ./my.cnf: Permission denied ?  /etc sudo cp /Users/a1/Desktop/my.cnf ./ Password: ?  /etc ll total 1064 ...... -rw-------   1 root  wheel   7.3K  2 29 14:10 master.passwd -rw-r--r--   1 root  wheel   1.2K  5 17 17:24 my.cnf -rw-r--r--   1 root  wheel    11B  2 29 14:43 nanorc -rw-r--r--   1 root  wheel    53B  2 29 14:09 networks ...... ?  /etc

備注：拷貝文件到etc目錄需要系統權限，因此需要在命令前加sudo

檢測修改結果

備注：此時不輸入密碼就登錄不了數據庫了，必須使用修改后的密碼登錄數據庫了，并且數據庫的字符集編碼信息已經修改了。

至此，就可以愉快的使用數據庫了！！！
