我正在尝试通过ssh对bitnami的wordpress多层堆栈进行数据库管理，特别是我想导出并进行初始导入（尽管我可能只会创建一个新的数据库）。
运行以下命令时，出现以下错误：
命令： mysqldump -u root -p bitnami_wordpress > bitnami_wordpress.sql 输出： mysqldump: Got error: 2002: "Can't connect to local MySQL server through socket '/opt/bitnami/mariadb/tmp/mysql.sock' (2)" when trying to connect 这还会在我的主目录中创建一个0b sql文件。
命令： mysqladmin -u root -p status （我输入密码）
输出：

mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket . 
'/opt/bitnami/mariadb/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: 
'/opt/bitnami/mariadb/tmp/mysql.sock' exists!

命令： cd /opt/bitnami/mariadb/ + ls 输出：

bin                 CREDITS            include         licenses   README-wsrep
COPYING             data               INSTALL-BINARY  plugin     sbin
COPYING.thirdparty  EXCEPTIONS-CLIENT  lib             README.md  share

命令： sudo find . -name mysql 输出：

输出：无

find /opt/bitnami/mariadb/ -name "my.cnf"

输出：

/opt/bitnami/mariadb/share/my-huge.cnf
/opt/bitnami/mariadb/share/wsrep.cnf

命令： nano /opt/bitnami/mariadb/share/my-medium.cnf （我的中号、小号和大号有什么区别）？
输出：

# The following options will be passed to all MariaDB clients

[client]

# password       = your_password

port            = 3306
socket          = /opt/bitnami/mariadb/tmp/mysql.sock

注： /opt/bitnami/mariadb/tmp/mysql.sock 不存在。
我浏览了一下mariadb关于2002年错误的文档，但是我似乎没有相同的.conf文件（我也不知道在哪里查找）
…从这里我不知道去哪里，我只通过shell做了有限的数据库管理。
简明问题：
如何导出数据库而不出现2002错误？
如何覆盖/更新数据库？
任何帮助将不胜感激，并提前感谢！
