Question

我正在尝试通过SSH对Bitnami's WordPress Multi-tier Stack /进行数据库管理/具体来说，我想导出并进行初始导入（尽管我可能只会创建一个新数据库）。

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：

命令：

find /opt/bitnami/mysql/ -name "*.cnf"

输出：没什么

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

输出：

/opt/bitnami/mariadb/share/my-medium.cnf
/opt/bitnami/mariadb/share/my-small.cnf
/opt/bitnami/mariadb/share/my-large.cnf
/opt/bitnami/mariadb/share/my-innodb-heavy-4G.cnf
/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，我的小号和我的大号之间有什么区别）？

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

注意：/opt/bitnami/mariadb/tmp/mysql.sock不存在。

我已经戳了一下，发现MariaDB's Documentation about 2002 errors，但是我似乎没有相同的.conf文件（也不知道在哪里查找）

...从这里开始，我不知道要去哪里，我只通过shell进行了有限的数据库管理。

简明的问题：

如何在不获取2002 error的情况下导出数据库？
如何覆盖/更新数据库？

任何帮助将不胜感激，并在此先感谢！

Bitnami的人们来了。我连接到错误的主机。

查找主机： sudo cat /opt/bitnami/wordpress/wp-config.php | grep 'DB_HOST'

要导出：

mysqldump -h provisioner-peer -u root -p bitnami_wordpress > bitnami_wordpress.sql

尝试在Bitnami的WordPress多层堆栈中导入/导出MariaDB数据库时出现2002代码错误
