小編給大家分享一下如何在Mac下搭建MySQL環境,希望大家閱讀完這篇文章之后都有所收獲,下面讓我們一起去探討吧!
1、安裝
官網下載好 MySQL Mac 版安裝包,常規步驟安裝,安裝過程中會出現如下提示:
2019-03-24T18:27:31.043133Z 1 [Note] A temporary password is generated for root@localhost: TdfRm19!o0Xi
其中TdfRm19!o0Xi
是初始密碼,最好先記住!
2、登陸
在終端命令行 登陸mysql:
$ mysql -u root -p # 輸入上述密碼即可
如果這一步提示: bash: mysql: command not found
, 執行下面2個命令做個軟連接即可:
cd /usr/local/bin ln -fs /usr/local/mysql-8.0.11-macos10.13-x86_64/bin/mysql mysql
3、修改密碼
在 MySQL8.0.4 以前,執行 SET PASSWORD=PASSWORD('新密碼')
即可。但新版本不能這樣改了,因為密碼認證變了。具體步驟可以參考 https://blog.csdn.net/yi247630676/article/details/80352655。
總所周知,Mac 可以利用 homebrew 進行安裝管理,十分方便,如果沒有安裝 homebrew, 可以點擊 https://brew.sh/ 安裝。
下面是 mysql 的安裝方式
$ brew install mysql # 安裝指定版本: brew install mysql@1.1.1
接下來只要等待就可以了,出現下面文字后我們已經很清楚我們需要做什么了:
==> mysql We've installed your MySQL database without a root password. To secure it run: mysql_secure_installation MySQL is configured to only allow connections from localhost by default To connect run: mysql -u root To have launchd start mysql now and restart at login: brew services start mysql Or, if you don't want/need a background service you can just run: mysql.server start
按說明繼續執行,進行初始化操作:
$ myysql_secure_installation
初始化過程中會有很多問題,以下是具體問題部分,以注釋為解釋:
Would you like to setup VALIDATE PASSWORD component? Press y|Y for Yes, any other key for No: Y ## 回復y 需要密碼8位以上,回復n 則不做限制 The password validation component is not available. Proceeding with the further steps without the component. Please set the password for root here. New password: ## 設置你的密碼 Re-enter new password: ## 再次輸入你的密碼 By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y ## 是否移除匿名用戶。考慮安全我選了y Success. Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y ## 是否允許遠程連mysql 的 root。我用做本地調試,不是遠程服務器,所以y了 Success. By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y ## 是否y了刪除test數據庫,我選了y - Dropping test database... Success. - Removing privileges on test database... Success. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y ## 選y, 重新加載權限列表 Success. All done!
到此配置就結束了,下面我們啟動 mysql 即可,記住以下命令:
$ mysql -u root -p ## 登陸 mysql $ brew services start mysql@5.7 ## 啟動 mysql $ brew services stop mysql@5.7 ## 停止 mysql $ mysql.server start ## 啟動 mysql(無后臺服務)
