Mac 安装mysql(Homebrew)

Mac通过Homebrew安装MySQL

一、安装

安装Homebrew

参见： Mac安装Homebrew

注意，如果之前已经安装过的话，需要先删除如下的文件或者目录；如果是全新安装，这一步可以忽略

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、执行安装命令

brew install mysql@5.7   # 这里一定要加上版本号，否则是安装最新的，比如最新的是8.0.19，则可能有些早期的mysql客户端无法链接

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、创建软连接(可选，如果不存在就需要创建，为了方便/usr/local/bin加入环境变量的情况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、启动mysql

mysql.server start

2.1、首次连接：

 mysql -uroot

3、停止mysql

mysql.server stop

4、修改root密码：

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

5、执行安全设置

mysql_secure_installation

显示如下

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

按照提示选择密码等级，并设置root密码

二、创建新的数据库、用户并授权

1、登录mysql

mysql -u root -p

按提示输入root密码

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

2、创建数据库

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

3、创建用户

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

4、授权用户

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

flush privileges;

5、查看数据库列表

show databases;

6、切换数据库；

use allinone;  # allinone 为数据库名称

7、显示当前数据库所有的表

show tables

三、建表

CREATE TABLE `xmind2chandaocase` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `type` int(11) NOT NULL COMMENT \'上传xmind文件进行解析:upload=1;\\n从禅道导出未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、检查mysql状态

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 %
