Ubuntu:无法通过套接字'/var/run/mysqld/mysqld.sock'连接到本地MySQL服务器(2)
我有一个 Ubuntu 14.04.在运行 Owncloud 的地方安装了 LAMP 的服务器.我尝试安装 paperwork 但没有成功但这不是问题.
I have a Ubuntu 14.04. server with LAMP installed where an Owncloud is running. I tried to install paperwork which didn't work out but thats not the problem.
重新启动服务器后，我尝试再次访问自己的云，但遇到内部服务器错误.见下图.自己的云错误
After restarting my server I tried to access my owncloud again but I am facing an internal server error. See following picture. Owncloud error
我查看了日志/var/log/apache2/error.log 并且有以下短语:
I looked in the log /var/log/apache2/error.log and theres following phrase:
Lost connection to MySQL server during query' in ...
我尝试重启mysql服务但是出现这个错误:
I tried to restart the mysql service but this error appears:
stop: Unknown instance:
start: Job failed to start
然后我尝试使用 mysql -u root -p 登录到 mysql 并且出现以下错误:
Then I tried to login to mysql with mysql -u root -p and follorwing error appears:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
我用 find/-type s 在机器上寻找套接字，套接字在那里: /run/mysqld/ .我创建了一个符号链接并将其粘贴到 /var/run/mysqld/mysqld.sock
I've looked for the sockets on the machine with find / -type s and the socket was there: /run/mysqld/ .
I created a symbolic link and pasted it to /var/run/mysqld/mysqld.sock
不幸的是没有任何效果.再次重新启动后，我再也找不到套接字 find/-type s 的输出是:
Unfortnutely nothing worked. After restarting again I can't find the socket anymore the output of find / -type s is:
/dev/log
/run/php5-fpm.sock
/run/udev/control
find: `/proc/977/task/977/fd/5': No such file or directory
find: `/proc/977/task/977/fdinfo/5': No such file or directory
find: `/proc/977/fd/5': No such file or directory
find: `/proc/977/fdinfo/5': No such file or directory
更新
我已经重新安装了服务器，所以问题解决了 :D
I've reinstalled the server so problem is over :D
推荐答案
如果你安装了lampp服务器，先运行mysql
If you install lampp server, run mysql first
sudo /opt/lampp/lampp startmysql
然后在/var/run 中创建mysqld"目录
Then make "mysqld" directory in /var/run
cd /var/run
sudo mkdir mysqld
将你的mysql从lampp链接到/var/run/mysqld
Link your mysql from lampp to /var/run/mysqld
sudo ln -s /opt/lampp/var/mysql/mysql.sock /var/run/mysqld/mysqld.sock
运行 mysql -u root -p .希望能帮到你
run mysql -u root -p . hope may help you
