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。我已经在此处下载了 Mac OS X 10.9(x86,64 位)压缩的 TAR 存档:http://dev.mysql.com/downloads/mysql/
正如教程所说,我在终端中输入以下命令:
/Users/myuser/Downloads/mysql-5.6.24-osx10.9-x86_64/bin/mysql/mysql -u root -p mypassword
首先,终端要求输入我的密码,当我输入密码时,会发生以下错误:
错误2002(HY000):无法通过套接字'/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,使用上面的命令修复它。
OSX 10.13.2 High Sierra
mariadb 10.2.12
当我尝试使用
mariadb
时,我遇到了完全相同的错误,我用自制软件安装了它。安装后我做的第一件事是:
$ 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

我发现的手动启动和停止 mariadb 的最佳说明却在 自动启动和停止 MariaDB:
您可以选择启动几种不同的 mysqld 服务器 方法:
运行或调用 mysqld 本身。从源目录运行 MariaDB 中详细描述了执行此操作的示例。
使用mysqld_safe启动脚本
使用mysql.server启动脚本
mysql.server 脚本首先更改为 MariaDB 来启动 mysqld 安装目录然后调用mysqld_safe。添加适当的 my.cnf 文件中的 [mysqld] 组的用户行将导致 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,您可能需要 编辑 mysql.server 脚本以使其正常工作。
mysql.server 作为标准 SysV 风格的初始化脚本工作。因此你 使用带有开始和停止参数的脚本,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)
我如何在我的 MAC + MAMP(专业版)设置上解决这个问题:
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,错误就不会再出现了。
在做任何激烈的事情之前,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
(如果您未指定 -h
,则默认使用该名称)通过命名管道而不是 TCP/IP 进行连接。如果未启用命名管道,这是您看到的错误消息。
这是一个常见错误,你可以这样修复它
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
如果您通过 Homebrew 安装了 Mysql,只需运行以下命令,就会很有帮助。
brew服务启动mysql
Homebrew 安装后将不会启动 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)
你只需要启动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,我设法通过以下方式修复它:
警告:在继续执行以下命令之前先备份所有数据库
rm -rf /usr/local/var/mysql
rm /usr/local/etc/my.cnf
brew postinstall [email protected] -v
mysqld
你可以尝试切换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
这对我有用,只需删除文件即可
$ rm /tmp/mysql.sock
然后$ brew services mariadb restart
这是一步一步。找到 pid 并杀死 -9 $PID...

是的,它也适合我...... 但我不明白:在两个 php.ini 文件conf(MAMP 的 apache 和 php)中,套接字路径都很好:
socket=/Applications/MAMP/tmp/mysql/mysql.sock
那么为什么还要寻找/tmp/mysql.sock
???
