Homebrew簡稱brew，OSX上的軟體包管理工具，在Mac終端可以通過brew安裝、更新、解除安裝各種軟體，(簡直就是神器級武器 )。
廢話不多說，沒安裝brew自己去百度學習安裝，這裡就不多說了。
1、首先在終端使用命令，這是搜尋brew上的SQL/">MySQL各個版本
brew search mysql
2、選擇自己需要的版本，安裝MySQL,這裡我安裝為5.7版本
brew install [email protected]
3、執行後稍等片刻，它會自動安裝，以下為安裝成功後顯示的資訊
MySQL is configured to only allow connections from localhost by default To connect run: mysql -uroot [email protected] is keg-only, which means it was not symlinked into /usr/local, because this is an alternate version of another formula. If you need to have [email protected] first in your PATH run: echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bash_profile For compilers to find [email protected] you may need to set: export LDFLAGS="-L/usr/local/opt/[email protected]/lib" export CPPFLAGS="-I/usr/local/opt/[email protected]/include" To have launchd start [email protected] now and restart at login: brew services start [email protected] Or, if you don't want/need a background service you can just run: /usr/local/opt/[email protected]/bin/mysql.server start ==> Summary :beer:/usr/local/Cellar/[email protected]/5.7.23: 317 files, 234.1MB
以上資訊需注意系統環境變數的配置：
echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bash_profile # 檔案修改以後執行寫入bash_profile以後執行立即生效 sousers ~/.bash_profile
4、最後執行,啟動MySQL
mysql.server start # 顯示如下，則安裝成功 Starting MySQL . SUCCESS!
附加：
終端輸入
mysql -u root
如果你運氣不好,出現如下錯誤,應該是修改初始密碼沒有成功
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES),
解決步驟
(1)終端輸入 mysqld_safe --skip-grant-tables 顯示如下
mysqld_safe --skip-grant-tables # 顯示如下 2017-03-21T11:44:11.6NZ mysqld_safe Logging to '/usr/local/var/mysql/huang.local.err'. 2017-03-21T11:44:11.6NZ mysqld_safe Logging to '/usr/local/var/mysql/huang.local.err'. 2017-03-21T11:44:11.6NZ mysqld_safe A mysqld process already exists
(2)再次輸入 mysql -u root 顯示如下
Welcome to the MySQL monitor.Commands end with ; or g. Your MySQL connection id is 10 Server version: 5.7.17 Homebrew Copyright (c) 2000, 2016, Oracle and/or its affiliates. All rights reserved.

(3)終端輸入 use mysql顯示如下
Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql>
(4)修改密碼 UPDATE mysql.user SET authentication_string=PASSWORD('你的密碼') WHERE User='root';
成功Query OK, 1 row affected, 1 warning (0.05 sec) Rows matched: 1Changed: 1Warnings: 1
到這來就完成啦。
最後重新登終端輸入：
mysql -u root -p
按回車鍵，輸入設定的密碼即可登入
以上所述給大家介紹的解決mac使用homebrew安裝MySQL，並出現無法登陸問題的解決方案,希望對大家有所幫助。
