Mysql连接到服务器：用户root @ localhost

edit9：我是否有可能在文件夹上缺少一些权限？我真的，真的很感激一些建议......

编辑3：因为这篇文章没有得到足够的回复，所以我尽快得到这个，我重新设计了我的帖子，以显示我认为到目前为止已扣除的内容。

注意：通过许多不同的命令正常登录根本不起作用。

我的流程：

  1. 删除运行以下命令的mysql（我忘了什么吗？）：

    2. sudo rm /usr/local/mysql sudo rm -rf /usr/local/mysql* sudo rm -rf /Library/StartupItems/MySQLCOM sudo rm -rf /Library/PreferencePanes/MySQL* rm -rf ~/Library/PreferencePanes/MySQL* sudo rm -rf /Library/Receipts/mysql* sudo rm -rf /Library/Receipts/MySQL* sudo rm -rf /var/db/receipts/com.mysql.*

    1. 从http://dev.mysql.com/downloads/mysql/

      2. 下载mysql-5.7.9-osx10.10-x86_64.dmg

    2. 在标准位置使用标准安装安装mysql-5.7.9-osx10.9-x86_64.pkg。 （为什么我下载10.10时pkg 10.9？我的OS X版本是10.10 yosemite）

    3. 我收到一条通知，告知已创建root @ localhost的临时密码。我写得很完美。

      4. 这是问题的起点。

      1. 尝试通过终端启动mysql服务器： sudo /usr/local/mysql/support-files/mysql.server start返回： Starting MySQL .. ERROR! The server quit without updating PID file (/var/run/mysqld/mysqld.pid).

      2. 经过对这个pid文件的一些研究，我意识到我需要在/ etc中创建my.cnf，所以我做了.. cd /usr/local/mysql/support-files/ sudo cp my-default.cnf /etc/my.cnf

      3. 编辑并保存my.cnf .. cd /etc sudo nano my.cnf，进入第 pid-file = /var/run/mysqld/mysqld.pid行

      4. 创建目录..

        sudo mkdir / var / run / mysqld sudo touch /var/run/mysqld/mysqld.pid sudo chown -R mysql：mysql / var / run / mysqld

      5. 假设my.cnf现在应该全部设置，包括pid文件。我试着再次启动服务器。但是没有任何改变。

        6. 好的，所以我觉得很好，我会尝试更改安装时临时设置的密码。

        1. 我停止了mysql服务器（它不应该运行，但以防万一）。 sudo /usr/local/mysql/support-files/mysql.server stop。这可能很有趣，因为我最终会以某种形式出现，我无法做任何事情。我必须从这里重新启动终端。

        2. 尝试使用sudo mysql_safe --skip-grant-tables以安全模式启动mysql：

          151110 10:28:10 mysqld_safe记录到'/usr/local/var/mysql/Robs-MacBook-Pro.local.err'。 151110 10:28:10 mysqld_safe用/ usr / local / var / mysql中的数据库启动mysqld守护进程 151110 10:28:10来自pid文件的mysqld_safe mysqld /usr/local/var/mysql/Robs-MacBook-Pro.local.pid已结束

          3. 所以再一次关于这个pid文件..我没有在这里为basedir / datadir / port / server_id / socket设置值..也许就是这样？如果是这样，我应该在这里设置什么值？

          当我在互联网上提出不同建议时经常出现的其他错误包括： Access denied for user root@localhost using password: yes/no或 Cant connect to mysql server through socket ..

          /usr/local/var/mysql/data/mysqld.local.err最后几行：

          来自Vasfed的一个好建议的结果： 然后，按照描述创建txt文件。使用我用过的目录和文件名输入命令：mysqld_safe --init-file=/home/mysql-init & 哪个返回：Robs-MacBook-Pro:home leroyklotz$ 151118 09:25:23 mysqld_safe Logging to '/usr/local/var/mysql/Robs-MacBook-Pro.local.err'. 151118 09:25:23 mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql /usr/local/bin/mysqld_safe: line 129: /usr/local/var/mysql/Robs-MacBook-Pro.local.err: Permission denied rm: /tmp/mysql.sock: Permission denied /usr/local/bin/mysqld_safe: line 166: /usr/local/var/mysql/Robs-MacBook-Pro.local.err: Permission denied 151118 09:25:23 mysqld_safe mysqld from pid file /usr/local/var/mysql/Robs-MacBook-Pro.local.pid ended /usr/local/bin/mysqld_safe: line 129: /usr/local/var/mysql/Robs-MacBook-Pro.local.err: Permission denied

          授予Robs-MacBook-Pro.local.err和mysql.sock（仍称为mysql.sock.lock，这有关系吗？）的权限并不能完全解决问题，现在的错误信息如下： 

          Robs-MacBook-Pro:~ leroyklotz$ mysqld_safe --init-file=/home/mysql-init &

答案 0 :(得分：1)

不要自己创建/触摸pid文件，它旨在由守护程序本身创建以指示其pid

在macos上mysql运行正常，没有my.cnf

首先要查看/usr/local/var/mysql/Robs-MacBook-Pro.local.err的mysqld日志。

奇怪的位置，顺便说一句，默认是在/usr/local/mysql/data/<your_hostname>.err（需要sudo来阅读），可能是你安装的服务器根本没有启动而你有其他守护进程正在运行（例如通过自制软件安装）

检查ps ax | grep mysql | grep -v grep - 它应该有2个进程，两个都有/usr/local/mysql/bin中的二进制文件，如果还有其他mysql - 这解释了所有
