Homebrew簡稱brew，OSX上的軟件包管理工具，在Mac終端可以通過brew安裝、更新、卸載各種軟件，(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，這里就不多說了。
1、首先在終端使用命令，這是搜索brew上的MySQL各個版本
brew search mysql
2、選擇自己需要的版本，安裝MySQL,這里我安裝為5.7版本
brew install mysql@5.7
3、執行后稍等片刻，它會自動安裝，以下為安裝成功后顯示的信息
MySQL is configured to only allow connections from localhost by default
To connect run:
mysql -uroot
mysql@5.7 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 mysql@5.7 first in your PATH run:
echo 'export PATH="/usr/local/opt/mysql@5.7/bin:$PATH"' >> ~/.bash_profile
For compilers to find mysql@5.7 you may need to set:
export LDFLAGS="-L/usr/local/opt/mysql@5.7/lib"
export CPPFLAGS="-I/usr/local/opt/mysql@5.7/include"
To have launchd start mysql@5.7 now and restart at login:
brew services start mysql@5.7
Or, if you don't want/need a background service you can just run:
/usr/local/opt/mysql@5.7/bin/mysql.server start
==> Summary
🍺 /usr/local/Cellar/mysql@5.7/5.7.23: 317 files, 234.1MB
以上信息需注意系統環境變量的配置：
echo 'export PATH="/usr/local/opt/mysql@5.7/bin:$PATH"' >> ~/.bash_profile
# 文件修改以后執行寫入bash_profile以后執行立即生效
sousers ~/.bash_profile
4、最后執行,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

mysql>
(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: 1 Changed: 1 Warnings: 1
到這來就完成啦。
最后重新登終端輸入：
mysql -u root -p
按回車鍵，輸入設置的密碼即可登錄
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。
