Mysql连接到服务器:用户root@localhost拒绝访问。

edit9: Is it a possibility that I'm simply missing a few permissions on folders? I'd really, REALLY appreciate some more suggestions..

edit9:我可能只是缺少一些文件夹的权限吗?我真的很感激你的建议。

edit3: As this post did not get enough replies and it is absolutely vital I get this going as soon as possible I reconstructed my post to display what I think I have deducted so far.

Note: logging in normally via numerous different commands simply did not work.

注意:通常通过许多不同的命令登录，根本不起作用。

I get a notification that a temporary password for root@localhost has been created. I wrote this down perfectly.

我得到一个通知，创建了root@localhost的临时密码。我写得很完美。

Here is where the problems start.

这里是问题开始的地方。

Attempting to start mysql server via terminal with: sudo /usr/local/mysql/support-files/mysql.server start returns: Starting MySQL .. ERROR! The server quit without updating PID file (/var/run/mysqld/mysqld.pid).

试图通过终端启动mysql服务器:sudo / usr/local/mysql/supportfiles /mysql。服务器启动返回:启动MySQL ..错误!服务器在不更新PID文件(/var/run/mysqld/mysqld. PID)的情况下退出。
After some research about this pid file I realized I needed to create my.cnf in /etc, so I did.. cd /usr/local/mysql/support-files/ sudo cp my-default.cnf /etc/my.cnf

在对这个pid文件进行了一些研究之后，我意识到我需要在/etc中创建my.cnf，所以我做到了。cd / usr/local/mysql/supportfiles / sudo cp my-default.cnf /etc/my.cnf。
Edited and saved my.cnf.. cd /etc sudo nano my.cnf, entered the line pid-file = /var/run/mysqld/mysqld.pid

. .编辑并保存my . cnf中所做cd /etc sudo nano my.cnf，输入行文件= /var/run/mysqld/mysqld.pid。
Created the directory..

创建该目录。

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

sudo mkdir /var/run/mysqld sudo touch /var/run/mysqld/mysqld。pid sudo chown -R mysql:mysql /var/run/mysqld。
Assuming my.cnf should be all set now including the pid file. I tried to start the server again. However nothing has changed.

假设my.cnf现在都设置为pid文件。我试着重新启动服务器。但是什么都没有改变。

Okay, so then I decided fine, I'll try to change the password that was temporarily set when I installed.

好的，然后我决定好了，我将试着修改安装时临时设置的密码。

I stop the mysql server (it shouldn't be running, but just in case). sudo /usr/local/mysql/support-files/mysql.server stop. This might be interesting because I end up in some sort of shell form in which I am not able to do anything whatsoever. I have to restart terminal from here.

我停止mysql服务器(它不应该运行，只是以防万一)。sudo /usr/local/mysql/support-files / mysql。服务器停止。这可能很有趣，因为我最终以某种形式，我不能做任何事情。我必须从这里重新启动终端。
Trying to start mysql in safe mode with sudo mysql_safe --skip-grant-tables returns:

尝试使用sudo mysql_safe——skip-grant表返回安全模式的mysql。

151110 10:28:10 mysqld_safe Logging to '/usr/local/var/mysql/Robs-MacBook-Pro.local.err'. 151110 10:28:10 mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql 151110 10:28:10 mysqld_safe mysqld from pid file /usr/local/var/mysql/Robs-MacBook-Pro.local.pid ended

151110 10:10 mysqld_safe登录到/usr/local/var/mysql/Robs-MacBook-Pro.local.err。mysqld_safe启动mysqld守护进程，数据库来自/usr/local/var/mysql 151110 10:28:10 mysqld_safe mysqld，从pid文件/ usr/local/var/mysql/robs-macbookpro.local。pid结束

So again it's all about this pid file.. I have no values set for basedir/datadir/port/server_id/socket here.. Perhaps that is it? If so what values should I set here?

这就是这个pid文件。我没有为basedir/datadir/port/server_id/socket设置值。也许这是吗?如果有，我应该在这里设置什么值?

Other errors that regularly occur when I fiddle around with different suggestions on the internet include: Access denied for user root@localhost using password: yes/no or Cant connect to mysql server through socket ..

当我在互联网上随意修改建议时，经常会出现的其他错误包括:用户root@localhost被拒绝使用密码:yes/no或不能通过socket连接到mysql服务器。

Outcome to a nice suggestion from Vasfed: Then, creating the txt file as described. Entered the command with my used directory and filename: mysqld_safe --init-file=/home/mysql-init & Which returns: 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

从Vasfed得到一个不错的建议:然后，按照描述创建txt文件。使用我使用的目录和文件名输入命令:mysqld_safe—init-file=/home/mysql-init &返回:robs - macbookpro:home leroyklotz$ 151118 09:25:23 mysqld_safe日志到'/usr/local/var/mysql/Robs-MacBook-Pro.local.err'。使用数据库从/usr/local/var/mysql /usr/local/bin/mysqld_safe:第129行:/ usr/local/var/mysql/robs-macbookpro.local。err:权限拒绝rm: /tmp/mysql。sock:权限拒绝/usr/local/bin/mysqld_safe:第166行:/ usr/local/var/mysql/robs-macbookpro.local。err:允许从pid文件/usr/local/var/mysql/Robs-MacBook-Pro.local中删除mysqld_safe mysqld。pid结束/usr/local/bin/mysqld_safe:第129行:/ usr/local/var/mysql/robs-macbookpro.local。错:没有权限

Granting permissions on Robs-MacBook-Pro.local.err and mysql.sock (which is still called mysql.sock.lock, does this matter?)does not completely solve the issue, error message now reads:

Robs-MacBook-Pro.local授予权限。犯错和mysql。袜子(它仍然被称为mysql.sock。锁，这要紧吗?)不完全解决问题，错误消息现在读:

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

Do not create/touch pid file yourself, it's intended to be created by daemon itself to indicate its pid

不要自己创建/触摸pid文件，它是由守护进程自己创建的，以显示它的pid ?

On macos mysql should run fine without my.cnf

在macos mysql中，没有my.cnf就可以运行。

First thing is to look into mysqld logs at /usr/local/var/mysql/Robs-MacBook-Pro.local.err.

首先要查看/ usr/local/var/mysql/robs-macbookpro.local.err中的mysqld日志。

Strange location, btw, default is in /usr/local/mysql/data/<your_hostname>.err (need sudo to read), may be your installed server does not start at all and you have other daemon running (for example installed via homebrew)

奇怪的位置，btw，默认值是/usr/local/mysql/data/ 。err(需要sudo来读取)，可能是您安装的服务器没有启动，并且您还运行了其他守护进程(例如通过homebrew安装)

Check ps ax | grep mysql | grep -v grep - it should have 2 processes, both with binaries in /usr/local/mysql/bin, if there's other mysql - this explains all

检查ps ax | grep mysql | grep -v grep -它应该有2个进程，都是在/usr/local/mysql/bin中的二进制文件，如果还有其他的mysql，这说明了所有的问题。
