brew在mac os上安装mysql-Java 学习之路

302

我正在尝试使用Homebrew by brew install mysql 5.1.52 在mac os 10.6上设置MySQL .

一切顺利，我也成功了 mysql_install_db .
但是当我尝试使用以下命令连接到服务器时：

/usr/local/Cellar/mysql/5.1.52/bin/mysqladmin -u root password 'mypass'

我明白了：

/usr/local/Cellar/mysql/5.1.52/bin/mysqladmin: connect to server at 'localhost' 
failed error: 'Access denied for user 'root'@'localhost' (using password: NO)'

我也尝试过访问 mysqladmin or mysql using -u root -proot ，
但无论是否有密码都无效 .

这是在全新机器上的全新安装，据我所知，必须可以在没有root密码的情况下访问新安装 . 我也尝试过：

/usr/local/Cellar/mysql/5.1.52/bin/mysql_secure_installation

但我也明白了

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

如果brew安装了MySQL 5.7，则该过程与以前的版本略有不同 . 要重置root密码，请执行以下操作：
```
sudo rm -rf /usr/local/var/mysql
mysqld --initialize
```
临时密码将打印到控制台，它只能用于更新root密码：
```
mysql.server start
echo "ALTER USER 'root'@'localhost' IDENTIFIED BY 'my-new-password';" | mysql -uroot --password=TEMPORARY_PASSWORD
```

我认为已经安装了旧版本的mysql，最终可能会处于这个位置 . 我遇到了同样的问题，上述解决方案都没有对我有用 . 我这样解决了：

使用brew的 remove ＆ cleanup 命令，卸载了 launchctl 脚本，然后删除了 /usr/local/var 中的mysql目录，删除了我现有的 /etc/my.cnf （请保留那个，如果它适用）和launchctl plist

更新了plist的字符串 . 另请注意，您的备用安全脚本目录将基于您要安装的MySQL版本 .

一步步：
```
brew remove mysql

brew cleanup

launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

sudo rm -rf /usr/local/var/mysql
```
然后我从头开始：
- 用 brew install mysql 安装了mysql
- 运行brew建议的命令:(见下面注释）
```
unset TMPDIR

mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
```
- 用 mysql.server start 命令启动mysql，以便能够登录它
- 使用备用安全脚本：
```
/usr/local/Cellar/mysql/5.5.10/bin/mysql_secure_installation
```
- 跟随brew包脚本输出中的 launchctl 部分，例如，
```
#start
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

#stop
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
```
- 轰隆 .
希望有人帮助！

Note: brew cleanup 上的 --force 位也将清理过时的小桶，认为这是一个新的自制功能 .

Note the second: 评论者说第2步不是必需的 . 我不想测试它，所以YMMV！

这里有详细的说明，结合摆脱Mac上的所有MySQL，然后安装它作为Sedorner的Brew Way上面写道：

根据技术实验室完全删除MySQL
- ps -ax | grep mysql
- stop和 kill 任何MySQL进程
- sudo rm /usr/local/mysql
- sudo rm -rf /usr/local/var/mysql
- sudo rm -rf /usr/local/mysql*
- sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
- sudo rm -rf /Library/StartupItems/MySQLCOM
- sudo rm -rf /Library/PreferencePanes/My*
- launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
- 编辑 /etc/hostconfig 并删除行 MYSQLCOM=-YES-
- rm -rf ~/Library/PreferencePanes/My*
- sudo rm -rf /Library/Receipts/mysql*
- sudo rm -rf /Library/Receipts/MySQL*
- sudo rm -rf /private/var/db/receipts/*mysql*
- 尝试运行 mysql ，它应该不起作用
Brew从此StackOverflow答案中为每个用户Sedorner安装MySQL
- brew doctor 并修正任何错误
- brew remove mysql
- brew cleanup
- brew update
- brew install mysql
- unset TMPDIR
- mysql_install_db --verbose --user= whoami --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
- mysql.server start
- 运行Brew建议的命令，将MySQL添加到 launchctl ，以便它在启动时自动启动
mysql 现在应该可以正常运行并按预期运行

一帆风顺 .

有同样的问题 . 似乎设置说明或正在创建的初始表有问题 . 这就是我在我的机器上运行mysqld的方法 .

如果mysqld服务器已在Mac上运行，请先停止它：

launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

使用以下命令启动mysqld服务器，该命令允许任何人以完全权限登录 .

mysqld_safe --skip-grant-tables

然后运行 mysql -u root ，现在可以让您在没有密码的情况下成功登录 . 以下命令应重置所有root密码 .

UPDATE mysql.user SET Password=PASSWORD('NewPassword') WHERE User='root'; FLUSH PRIVILEGES;

现在，如果您终止mysqld_safe的运行副本并在没有skip-grant-tables选项的情况下再次启动它，您应该能够使用 mysql -u root -p 和您刚刚设置的新密码登录 .

好吧我有同样的问题并解决了它 . 出于某种原因，当使用Homebrew安装mysql时，mysql_secure_installation脚本无法正常工作，所以我手动完成了 . On the CLI enter ：
```
mysql -u root
```
这应该让你进入mysql . 现在执行以下操作（取自mysql_secure_installation）：
```
UPDATE mysql.user SET Password=PASSWORD('your_new_pass') WHERE User='root';
DELETE FROM mysql.user WHERE User='root' AND Host NOT IN ('localhost', '127.0.0.1', '::1');
DELETE FROM mysql.user WHERE User='';
DELETE FROM mysql.db WHERE Db='test' OR Db='test\\_%'
DROP DATABASE test;
FLUSH PRIVILEGES;
```
现在退出并返回到mysql： mysql -u root -p

我刚才遇到了同样的问题 . 如果你 brew info mysql 并按照步骤看起来根密码应该是 new-password 如果我没记错的话 . 我看到了你所看到的同样的事情 . This article对我帮助最大 .

事实证明我没有为我创建任何帐户 . 当我在运行 mysqld_safe 后登录并且 select * from user; 没有返回任何行 . 我打开MySQLWorkbench并运行 mysqld_safe 并添加了一个 root 帐户，其中包含我预期的所有权限 . 这对我来说效果很好 .

如果已经安装了mysql

完全停止mysql .
- mysql.server stop < - 可能需要根据您的版本进行编辑
- ps -ef | grep mysql < - 列出名称中包含mysql的进程
- kill [PID] < - 通过PID终止进程
删除文件 . 上面的说明很好 . 我要补充一下：
- sudo find /. -name "*mysql*"
- 用你的判断， rm -rf 这些文件 . 请注意，许多程序都有mysql驱动程序，您不想删除它们 . 例如，don 't delete stuff in a PHP install' s目录 . 在自己的mysql目录中删除东西 .
安装

希望你有自制软件 . 如果没有，请下载它 .

我喜欢以root身份运行brew，但我不认为你必须这样做 . 编辑2018：您不能再以root身份运行brew
- sudo brew update
- sudo brew install cmake < - 对mysql的依赖，很有用
- sudo brew install openssl < - 对mysql的依赖，很有用
- sudo brew info mysql < - 浏览一遍......它让您了解接下来会发生什么
- sudo brew install mysql --with-embedded; say done < - 使用嵌入式服务器安装mysql . 告诉你什么时候完成（我的安装花了10分钟）
之后
- sudo chown -R mysql /usr/local/var/mysql/ < - 在我运行此命令之前，mysql对我不起作用
- sudo mysql.server start < - 再一次，确切的语法可能会有所不同
- 在mysql中创建用户（http://dev.mysql.com/doc/refman/5.7/en/create-user.html） . 请记住为root用户添加密码 .

    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

mysql.service启动

. ERROR! The server quit without updating PID file (/var/run/mysqld/mysqld.pid).

或者mysql -u root

我正在寻找一段时间的解决方案，但我无法解决我的问题 . 我在stackoverflow.com上尝试了几个解决方案，但没有这个帮助我 .

TL;DR

使用Brew安装后，MySQL服务器可能无法运行 . 如果您不希望MySQL作为后台服务运行，请尝试 brew services start mysql 或仅 mysql.server start .

Full Story:

我刚刚在运行Sierra的新MacBook Pro上安装了MySQL（稳定版）5.7.17，并且在运行_580634时也遇到了错误：
```
Securing the MySQL server deployment.

Enter password for user root: 
Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
```
说什么？

根据Brew的安装信息， mysql_secure_installation 应该提示我......确保安装 . 我认为MySQL服务器可能没有正常运行 . 运行 brew services start mysql 然后 mysql_secure_installation 就像一个魅力 .

当使用brew与最新版本的mysql和yosemite时，上述答案（或我在其他地方看到的任何答案中的任何一个）都没有为我工作 . 我最终通过brew安装了一个不同的mysql版本 .

通过说（例如）指定旧版本
```
brew install mysql56
```
为我工作 . 希望这有助于某人 . 这是一个令人沮丧的问题，我觉得我永远陷入困境 .

我尝试重新启动mysql后遇到了同样的问题 .

为方便起见，我在.profile中使用了以下两个别名
```
alias mysql-stop='launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist'
alias mysql-start='launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist'
```
在停止mysql然后尝试重新启动后，我遇到了你遇到的问题 . 我查看了launchctl加载，它报告了“没有发现加载”错误 .

快速搜索后我发现了这个..

http://www.daveoncode.com/2013/02/01/solve-mac-osx-launchctl-nothing-found-to-load-error/

所以我更新了 mysql-start 别名，如下所示
```
alias mysql-start='launchctl load -w -F ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist'
```
这解决了我的问题，可能对您有用 .

Mysql的"Base-Path"存储在 /etc/my.cnf 中，当您进行brew升级时不会更新 . 只需打开它并更改basedir值即可

例如，改变这个：
```
[mysqld]
basedir=/Users/3st/homebrew/Cellar/mysql/5.6.13
```
指向新版本：
```
[mysqld]
basedir=/Users/3st/homebrew/Cellar/mysql/5.6.19
```
用以下命令重启mysql：
```
mysql.server start
```
