Mac终端ERROR 2002(HY000):无法通过套接字'/tmp/mysql.sock'连接到本地MySQL服务器(2)

Question

我正在按照本教程在Google云上设置Wordpress网站:https: //googlecloudplatform.github.io/appengine-php-wordpress-starter-project/

• 我正在使用OSX 10.10.3在Mac上工作.
• 我已经为Google App Engine软件安装了PHP SDK.

现在我正在尝试在我的mac上安装MySQL服务器.我在这里下载了Mac OS X 10.9(x86,64位)压缩TAR存档:http://dev.mysql.com/downloads/mysql/

正如教程所说,我在终端中命令以下行:

/Users/myuser/Downloads/mysql-5.6.24-osx10.9-x86_64/bin/mysql/mysql -u root -p mypassword

首先,终端要求输入密码,当我输入此密码时,会发生以下错误:

ERROR 2002(HY000):无法通过套接字'/tmp/mysql.sock'连接到本地MySQL服务器(2)

Answer 1

看起来Mysql服务器还没有启动.

mysqld stop
mysql.server start

有完全相同的问题,使用上面的命令来修复它.

Answer 2

这是一个常见的错误，你可以像这样修复它

您可以使用以下命令序列删除 root 密码：

$ mysql -u root
mysql> use mysql;
mysql> update user set password=PASSWORD("") where User='root';
mysql> flush privileges;
mysql> quit

Answer 3

错误： Mac terminal ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

如何在MAC + MAMP（pro）设置中解决此问题：

sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock

这会创建从/tmp/mysql.sock到MAMP mysql.sock的符号链接

现在重新启动MAMP，然后该错误不应再发生。

Answer 4

OSX 10.13.2 High Sierra
mariadb 10.2.12

当我尝试使用时mariadb,我得到了完全相同的错误,我用自制软件安装.安装后我做的第一件事就是:

$ mysql -u root
ERROR 2002 (HY000): Can't connect to local MySQL server through 
socket '/tmp/mysql.sock' (2)

为了排除故障,我做了:

~$ which mysql
/usr/local/mysql/bin/mysql

然后我试了一下:

~$ mysql -u 7stud -p test
 Enter password:
 ERROR 2002 (HY000): Can't connect to local MySQL server 
 through socket '/tmp/mysql.sock' (2)

和:

~$ mysql -u -p
ERROR 2002 (HY000): Can't connect to local MySQL server 
through socket '/tmp/mysql.sock' (2) 

解决方案:

~$ mysql.server start
Starting MySQL
.180127 00:24:48 mysqld_safe Logging to '/usr/local/var/mysql/MyMBP.home.err'.
180127 00:24:48 mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql
 SUCCESS! 

~$ mysql -u root

我发现手动启动和停止mariadb的最佳指令在自动启动和停止MariaDB时是矛盾的:

您可以选择以几种不同的方式启动mysqld服务器:

1. 运行或调用mysqld本身.执行此操作的示例在源目录中运行MariaDB中有更多描述.

2. 使用mysqld_safe启动脚本

3. 使用mysql.server启动脚本

mysql.server脚本首先更改为MariaDB安装目录然后调用mysqld_safe来启动mysqld.将适当的用户行添加到my.cnf文件中的[mysqld]组将导致服务器以该用户身份运行.

如果已将MariaDB安装到非标准位置,则可能需要编辑mysql.server脚本以使其正常工作.

mysql.server用作标准的SysV样式的init脚本.因此,您可以使用带有start和stop参数的脚本,如下所示:

mysql.server start
mysql.server stop

Answer 5

在做任何激烈的事情之前，请尝试使用回送地址127.0.0.1而不是默认的localhost.

mysql -h 127.0.0.1 -u root -p

localhost如果您不指定-h，默认情况下将使用name ，它通过命名管道而不是 TCP/IP 连接。这是您在未启用命名管道时看到的错误消息。
