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/
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,当我输入密码时,会出现以下错误:
ERROR 2002(HY000):无法通过socket' /tmp/mysql.sock'连接到本地MySQL服务器; (2)

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。
答案 1 :(得分:5)
OSX 10.13.2 High Sierra
mariadb 10.2.12
当我尝试使用mariadb
时,我得到了完全相同的错误,这是我用自制软件安装的。我在安装后做的第一件事就是:
$ mysql -u root
ERROR 2002 (HY000): Can't connect to local MySQL server through
socket '/tmp/mysql.sock' (2)
要排除故障,我做了:
~$ which mysql
/usr/local/mysql/bin/mysql
然后我尝试了:
~$ 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的最佳说明是Starting and Stopping MariaDB Automatically矛盾的:
您可以选择启动几个不同的mysqld服务器 方法:
运行或调用mysqld本身。执行此操作的示例将在源目录中运行MariaDB中进行更详细的描述。
使用mysqld_safe启动脚本
- 醇>
使用mysql.server启动脚本
mysql.server脚本首先更改为MariaDB,启动mysqld 安装目录,然后调用mysqld_safe。添加适当的 用户行到my.cnf文件中的[mysqld]组会导致 服务器以该用户身份运行。
如果您已将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作为标准的SysV样式的init脚本。就这样你 使用带有start和stop参数的脚本,如下所示:
mysql.server start mysql.server stop

错误:
Mac terminal ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
我是如何在我的MAC + MAMP(专业版)设置中解决这个问题的:
sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock
从/tmp/mysql.sock创建一个符号链接到MAMP mysql.sock
现在重新启动MAMP,然后不应再发生错误。

如果您通过Homebrew安装了Mysql,只需运行以下命令,这将有所帮助。
brew服务启动mysql
答案 5 :(得分:1)
您可以尝试切换mysql的版本。
以下是在Mac上使用HomeBrew的说明。
首先列出mysql的所有版本:
$ brew list --versions mysql
切换到旧版本:
$ brew services stop mysql
$ brew switch mysql 5.7.20
$ brew services start mysql
答案 6 :(得分:1)
一旦安装,Homebrew将无法启动mysql服务器,因此会出现错误。
$ brew services list
Name Status User Plist
mysql stopped
$ mysql -u root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2)
$ mysql -uroot
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2)
您只需要启动mysql服务,然后连接即可。
$ mysql.server start
Starting MySQL
. SUCCESS!
$ mysql -u root

如果您在通过 Homebrew 从 MySQL8 降级到 MySQL5.7 后在 MacOSX Catalina 上遇到此问题,我设法修复它:
警告:在继续执行以下命令之前备份所有数据库
rm -rf /usr/local/var/mysql
rm /usr/local/etc/my.cnf
brew postinstall mysql@5.7 -v
mysqld

答案 10 :(得分:0)
在进行任何大动作之前,请尝试使用环回地址127.0.0.1
而不是默认的localhost
进行连接。
mysql -h 127.0.0.1 -u root -p
名称localhost
通过命名管道而不是TCP / IP进行连接,如果您未指定-h
,则默认使用该名称。如果未启用命名管道,这是您看到的错误消息。
