Mac通過Homebrew安裝MySQL

一、安裝

安裝Homebrew

參見： Mac安裝Homebrew

注意，如果之前已經安裝過的話，需要先刪除如下的文件或者目錄；如果是全新安裝，這一步可以忽略

rm -rf /usr/local/etc/my.cnf*
rm -rf /usr/local/Cellar/mysql@5.7/
rm -rf /System/Volumes/Data/usr/local/Cellar/mysql@5.7
rm -rf /System/Volumes/Data/usr/local/etc/my.cnf
rm -rf /System/Volumes/Data/usr/local/Cellar/mysql@5.7

1、執行安裝命令

brew install mysql@5.7   # 這里一定要加上版本號，否則是安裝最新的，比如最新的是8.0.19，則可能有些早期的mysql客戶端無法鏈接

localhost:~ local$ brew install mysql
==> Downloading https://homebrew.bintray.com/bottles/mysql-5.6.26.yosemite.bottle.1.tar.gz
Already downloaded: /Library/Caches/Homebrew/mysql-5.6.26.yosemite.bottle.1.tar.gz
==> Pouring mysql-5.6.26.yosemite.bottle.1.tar.gz
==> Caveats
A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.

1.1、創建軟連接(可選，如果不存在就需要創建，為了方便/usr/local/bin加入環境變量的情況下可以直接使用命令)：

ln -s /usr/local/opt/mysql@5.7/bin/mysqladmin /usr/local/bin/mysqladmin
ln -s /usr/local/opt/mysql@5.7/bin/mysql.server /usr/local/bin/mysql.server
ln -s /usr/local/opt/mysql@5.7/bin/mysql /usr/local/bin/mysql

2、啟動mysql

mysql.server start

2.1、首次連接：

 mysql -uroot

3、停止mysql

mysql.server stop

4、修改root密碼：

/usr/local/bin/mysqladmin -u root password 1234567890(root的新密碼)
# /usr/local/bin/mysqladmin -> ../Cellar/mysql/8.0.19_1/bin/mysqladmin

5、執行安全設置

mysql_secure_installation

顯示如下

There are three levels of password validation policy:

LOW    Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file

按照提示選擇密碼等級，並設置root密碼

二、創建新的數據庫、用戶並授權

1、登錄mysql

mysql -u root -p

按提示輸入root密碼

local:~# mysql -u root -p
Enter password: 

2、創建數據庫

CREATE DATABASE IF NOT EXISTS `allinone` DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

3、創建用戶

create user 'adminuser'@'%' identified by 'test2020';

4、授權用戶

grant all privileges on allinone.* to 'adminuser'@'%';

flush privileges;

5、查看數據庫列表

show databases;

6、切換數據庫；

use allinone;  # allinone 為數據庫名稱

7、顯示當前數據庫所有的表

show tables

三、建表

CREATE TABLE `xmind2chandaocase` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `type` int(11) NOT NULL COMMENT '上傳xmind文件進行解析:upload=1;\n從禪道導出未xmind用例:export=2;',
  `fire_time` datetime NOT NULL,
  `ip` varchar(18) NOT NULL,
  `mac` varchar(48) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

四、檢查mysql狀態

local % mysql.server status
 SUCCESS! MySQL running (60677)
local % mysql.server stop  
Shutting down MySQL
.. SUCCESS! 
local % mysql.server status
 ERROR! MySQL is not running
local % mysql.server start            
Starting MySQL
. SUCCESS! 
local % mysql.server status
 SUCCESS! MySQL running (60992)
local %
