我想你的MySQL服务器还没有启动。因此，使用以下命令之一启动服务器。

#services mysql start

or

#/etc/init.d/mysql start

这应该在终端中完成，在服务器内部，当你的mysql数据库没有正确安装，当你得到这个错误:'无法连接到本地mysql服务器通过套接字'/var/run/mysqld/mysqld。袜子(2)。

停止MySql

sudo /etc/init.d/mysqld stop

重新启动或启动它

sudo /etc/init.d/mysqld restart or sudo /etc/init.d/mysqld start

像这样做一个链接，然后把它交给系统

ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock

运行一个安全安装，它可以指导你配置mysql所需的所有过程

/usr/bin/mysql_secure_installation

mysql。sock文件在MariaDB启动时创建，在MariaDB关闭时删除。如果MariaDB不运行，它就不存在。 也许你没有安装MariaDB。 你可以按照下面的说明操作: https://www.linode.com/docs/databases/mariadb/how-to-install-mariadb-on-centos-7 最好的

对于那些通过Vitess使用MySql的人。

我在vttablet组件收到这个错误，由于语法错误(忘记添加;to end of SQL命令)传递给init_db。在get started docs中作为示例给出的SQL:

apiVersion: v1
kind: Secret
metadata:
  name: my-cluster-config
type: Opaque
stringData:
  users.json: |
    {
      "user": [{
        "UserData": "user",
        "Password": "pass"
      }]
    }
  init_db.sql: |
    # This file is executed immediately after mysql_install_db,
    # to initialize a fresh data directory.
    CREATE DATABASE IF NOT EXISTS my_db <--- No ';' at the end

完整的错误日志:

TabletManager.ReplicationStatus()(on zone1from)错误: net.Dial(/vt/socket/mysql.sock) to local server失败 / vt /套筒/ mysql。Sock: connect:没有这样的文件或目录(errno 2002)

您必须安装mysql-server

apt install mysql-server

解决方法简单多了。

First, you have to locate(in Terminal with "sudo find / -type s") where your mysql.sock file is located. In my case it was in /opt/lampp/var/mysql/mysql.sock Fire up Terminal and issue sudo Nautilus This starts your Files manager with super user privileges From Nautilus navigate to where your mysql.sock file is located Right click on the file and select Make Link Rename the Link File to mysqld.sock then Right click on the file and Cut it Go to /var/run and create a folder called mysqld and enter it Now right click and Paste the Link File Voila! You will now have a mysqld.sock file at /var/run/mysqld/mysqld.sock :)
