MYSQL 未在 Ubuntu 操作系统上运行 - 错误 2002

发布于 2024-10-10 22:43:53 字数 2738 浏览 2 评论 0 原文

我是 mysql DB 的新手。我正在尝试在 Ubuntu 10.04 上运行 MYSQL Server。通过Synaptic Package Manager我已经安装了mysql版本:mysql-client-5.1

我想知道我通过上述方式安装的mysql-client软件的数据库密码是如何设置的。如果您能启发我,那就太好了这。

当我尝试运行此数据库时,遇到了以下错误:

mohnish@mohnish-laptop:/var/lib$ mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
mohnish@mohnish-laptop:/var/lib$ 

我引用了 其他用户发布的类似问题。我没有通过建议的答案找到解决方案。

例如,当我尝试针对类似问题发布的解决方案时,我得到以下结果:

mohnish@mohnish-laptop:/var/lib$ service start mysqld
start: unrecognized service
mohnish@mohnish-laptop:/var/lib$ ps -u mysql

我什至尝试引用 http://forums.mysql.com/read.php?11,27769,84713#msg-84713 但找不到任何有用的东西。

请让我知道如何解决这个错误。

非常感谢..

I am a novice to mysql DB. I am trying to run the MYSQL Server on Ubuntu 10.04. Through Synaptic Package Manager I am have installed the mysql version: mysql-client-5.1

I wonder that how was the database password set for the mysql-client software that I installed through the above way.It would be nice if you could enlighten me on this.

When I tried running this database, I encountered the error given below:

mohnish@mohnish-laptop:/var/lib$ mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
mohnish@mohnish-laptop:/var/lib$ 

I referred to a similar question posted by another user. I didn't find a solution through the proposed answers.

For instance when I tried the solutions posted for the similar question I got the following:

mohnish@mohnish-laptop:/var/lib$ service start mysqld
start: unrecognized service
mohnish@mohnish-laptop:/var/lib$ ps -u mysql

I even tried referring to http://forums.mysql.com/read.php?11,27769,84713#msg-84713 but couldn't find anything useful.

Please let me know how I could tackle this error.

Thank you very much..

mohnish@mohnish-laptop:/var/lib$ 服务 mysqld 启动 

看起来你没有安装mysql服务器包

sudo apt-get install mysql-server

应该有帮助

mohnish@mohnish-laptop:/var/lib$ service mysqld start 

looks like you did not install the mysql server package

sudo apt-get install mysql-server

should help

这确实属于服务器故障。

无论如何,您安装了 mysql-client 软件包,但您需要的是 mysql-server 软件包。客户端只是命令行客户端,而服务器则运行服务器本身。

在 Ubuntu 上安装后,您可以通过以下方式以 root 身份启动和停止它:

/etc/init.d/mysql start
/etc/init.d/mysql stop

This really belongs on serverfault.

Anyway, you installed the mysql-client package but what you need is the mysql-server package. The client is just the command-line client, while the server is what runs the server itself.

After installing it on Ubuntu, you can start and stop it as root via:

/etc/init.d/mysql start
/etc/init.d/mysql stop

使用以下命令

dpkg -l mysql* | grep ii | awk '{ print $2 }' | sudo xargs apt-get remove --purge -y 

&&

sudo apt-get install mysql-server

Use the following commands

dpkg -l mysql* | grep ii | awk '{ print $2 }' | sudo xargs apt-get remove --purge -y 

&&

sudo apt-get install mysql-server
