我正在尝试在我的终端上运行 mysql 客户端。我已经安装了最新的 mysql gem。

我无法摆脱上述错误。我在 /Users/HPV/expertiza/tmp/sockets 中创建了一个 mysql.sock 文件。在文件中我编写了mysql.default_socket =/expertiza/tmp/sockets/mysql.sock。

我做错了什么？

谢谢！

I am not able to get rid of the above error. I have created a mysql.sock file in /Users/HPV/expertiza/tmp/sockets. In the file I have written mysql.default_socket =/expertiza/tmp/sockets/mysql.sock.

What am I doing wrong?

Thanks!

您需要按照说明安装并启动服务器。

该命令根据您安装 MySQL 的方式而有所不同。首先尝试这个：

sudo /Library/StartupItems/MySQLCOM/MySQLCOM 启动

如果失败：

cd /usr/local/mysql
sudo ./bin/mysqld_safe
（如有必要，请输入您的密码）
（按 Control-Z）
背景

You need to follow the directions to install and start the server.

The command varies depending on how you installed MySQL. Try this first:

sudo /Library/StartupItems/MySQLCOM/MySQLCOM start

If that fails:

cd /usr/local/mysql
sudo ./bin/mysqld_safe
(Enter your password, if necessary)
(Press Control-Z)

另外，如果您遇到此错误并通过 Homebrew 安装了 mysql，我发现这可以工作（尽管您需要将“5.6.12”更改为您自己的版本）：

/usr/local/Cellar/mysql/5.6.12/bin/mysql.server重启

我刚刚在我的主目录中创建了一个文件 ~/restartMysql.sh （其中只有上面的行），这样我就可以在任何时候使用它MySQL 正在运行

Also, if you got this error and installed mysql via Homebrew, I found that this works (though you need to change "5.6.12" to your own version):

/usr/local/Cellar/mysql/5.6.12/bin/mysql.server restart

I just created a file ~/restartMysql.sh in my home directory (with only the line above in it) so that I can just use this whenever MySQL is acting up

这 post 帮助我完成了这件事，我将在这里重写这些步骤（注意：我还将编写您的命令的输出..只是为了让您知道你已经步入正轨）

如果正在运行，首先停止服务器：

[root@servert1 ~]# /etc/init.d/mysqld stop
Stopping MySQL: [ OK ]

在单独的线程上运行 sql 守护进程

[root@servert1 ~]# mysqld_safe --skip-grant-tables &    
[1] 13694    
[root@servert1 ~]# Starting mysqld daemon with databases from /var/lib/mysql

打开一个单独的 shell 窗口并输入

[root@servert1 ~]# mysql -u root

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 1

Server version: 5.0.77 Source distribution



Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

< em>开始使用 mysql

mysql> use mysql; 

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

使用新密码手动更新 user 表（注意：随意输入 mysql> showtables;
 只是为了了解您所在的位置）

注意：从 MySQL 5.7 开始，密码位于 authenication_string 表中，因此命令是 update user setauthentication_string=password ('testpass') where user='root';

mysql> update user set password=PASSWORD("testpass") where User='root';

Query OK, 3 rows affected (0.05 sec)

Rows matched: 3 Changed: 3 Warnings: 0

刷新权限（我不确定这个权限是什么......但它有效）

mysql> flush privileges; 

Query OK, 0 rows affected (0.04 sec)

退出

mysql> quit

Bye

停止服务器

注意：在 OS X 或 macOS 上，mysql.server 位于 /usr/local/mysql/support-files/。

mysql.server stop

Shutting down MySQL
.130421 09:27:02 mysqld_safe mysqld from pid file /usr/local/var/mysql/mycomputername.local.pid ended
 SUCCESS! 
[2]-  Done                    mysqld_safe --skip-grant-tables

杀死正在运行守护进程的其他 shell 窗口（只是为了确保）

现在就可以开始了！尝试一下：

[root@servert1 ~]#  mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>

完成！

this post helped did it for me, I'll rewrite the steps here (note: i'll be also writing the output of your commands.. just so that you know you're on track)

first stop the server if running:

[root@servert1 ~]# /etc/init.d/mysqld stop
Stopping MySQL: [ OK ]

run an sql dameon on a separate thread

[root@servert1 ~]# mysqld_safe --skip-grant-tables &    
[1] 13694    
[root@servert1 ~]# Starting mysqld daemon with databases from /var/lib/mysql

open a separate shell window and type

[root@servert1 ~]# mysql -u root

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 1

Server version: 5.0.77 Source distribution



Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

start using mysql 

mysql> use mysql; 

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

update the user table manually with your new password (note: feel free to type mysql> show tables;
 just to get a perspective on where you are)

NOTE: from MySQL 5.7 passwords are in the authenication_string table, so the command is update user set authentication_string=password('testpass') where user='root';

mysql> update user set password=PASSWORD("testpass") where User='root';

Query OK, 3 rows affected (0.05 sec)

Rows matched: 3 Changed: 3 Warnings: 0

flush privileges (i'm not sure what this privileges is all about.. but it works)

mysql> flush privileges; 

Query OK, 0 rows affected (0.04 sec)

quit

mysql> quit

Bye

stop the server

NOTE: on OS X or macOS, mysql.server is located at /usr/local/mysql/support-files/.

mysql.server stop

Shutting down MySQL
.130421 09:27:02 mysqld_safe mysqld from pid file /usr/local/var/mysql/mycomputername.local.pid ended
 SUCCESS! 
[2]-  Done                    mysqld_safe --skip-grant-tables

kill the other shell window that has the dameon running (just to make sure)

now you are good to go! try it:

[root@servert1 ~]#  mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 3

我希望这对某人有帮助。我遇到了同样的错误，但似乎与其他人有很大不同的原因。

我有 2 台 CentOS 机器。

我将my.cnf复制到新机器上，没有意识到我已经将旧机器升级到MySQL 5.6，而新机器安装了5.5。当我注释掉仅 5.6 的指令时，MySQL 按预期启动。 （现在我正在运行升级，以便我可以应用非常有用的 innodb_buffer_pool_dump_at_shutdown 和 innodb_buffer_pool_load_at_startup 指令）

我建议尝试最少的 my.cnf。如果 MySQL 启动，那么您就找到了问题的根源。

I hope this helps somebody. I was getting the same error, but seemingly for a much different reason than other people.

I have 2 CentOS machines.

I copied my.cnf to the new machine, not realizing that I had upgraded the old machine to MySQL 5.6, and the new machine had 5.5 installed. When I commented out the 5.6-only directives, MySQL started as expected. (and now I am running the upgrade so I can apply the massively useful innodb_buffer_pool_dump_at_shutdown and innodb_buffer_pool_load_at_startup directives)

I would suggest trying a bare minimum my.cnf. If MySQL starts up, then you've found the source of your problem.

看起来你需要安装一个 MySQL 服务器，mysql 的网站上有安装包，或者你可以通过 macports 安装（我假设是来自 darwin11 行）。
我通过端口安装了我的，套接字位于 /opt/local/var/run/mysql5/ 中。

It looks like you need a MySQL server installed, there is install packages on mysql's site, or you can install through macports (I assume from the darwin11 line).
I installed mine via ports, and the socket lives in /opt/local/var/run/mysql5/.

就我而言，我没有正确设置 tmp 文件夹。我通过这些步骤最终得到了什么：

1. cd /

2. ln -s private/tmp /tmp

In my case, I don't got tmp folder setting up right. What I end up with these steps:

1. cd /

2. ln -s private/tmp /tmp
