套接字不存在；无法通过套接字 '/var/run/mysqld/mysqld.sock' 连接到本地 MySQL 服务器 (2)

  • 772

我知道这个问题并不新鲜。但是我尝试了很多东西。我想不通的是，自从我下载了 mysql 后，socket 不可用。

/etc/my.cnf
/etc/mysql/my.cnf
/var/lib/mysql/my.cnf

以上文件均不可用。我一开始下载了mysql-server。由于它不起作用，我下载了 MariaDB。还是行不通。我可以用 MySql 做的是enable, restart（但不能启动）和version check. 我找不到其他我能做的事情。

尝试了以下所有链接等等。1、2、3 _ _ _ _

$-mysql -u root -p -h 127.0.0.1
Enter password: 
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1:3306' (111)

如果我执行，我会收到以下消息systemctl status mysql。

mysql.service - MySQL Community Server

我尝试重新安装mysql-server仍然是同样的问题。仅供参考，我也用lampp-server安装了它们，但我也找不到lampp文件夹/文件。

/etc/mysql$ ls
mariadb.conf.d  mysql.conf.d

mariadb.conf.d有50-client.cnf.dpkg-new 50-mysql-clients.cnf.dpkg-new 60-galera.cnf.dpkg-new并且mysql.conf.d是空的。

$ locate mysql.cnf
/etc/mysql/mysql.cnf
/etc/mysql/mysql.conf.d/mysql.cnf

但

/etc/mysql/mysql.conf.d$ cat mysql.cnf
cat: mysql.cnf: No such file or directory

$ cat /var/log/mysql/error.log

    经过比平时更长的思考，我意识到 MySQL 在我的系统中完全坏了。即使在删除 MySQL 时，也总会留下一些文件。所以我直接再次安装了一个新的发行版。再次从官方页面下载了 Xampp。

    $cd Downloads
$sudo chmod +x xampp.run
$sudo ./xampp.run

    然后出现一个对话框（安装），安装完成后，我在/opt中得到了一个Lampp文件夹。还有一个lampp可执行文件/opt/lampp/lampp

    cd /opt/lampp
sudo ./lampp start

    如果 lampp 不可执行，则运行

    sudo chmod +x lampp
