2002年在Bitnami的MariaDB多层堆栈中尝试导入/导出WordPress数据库时出错

Question

我试图通过SSH为Bitnami的WordPress多层堆栈/进行数据库管理，具体来说，我想导出并进行初始导入(尽管我可能只创建一个新的数据库)。

当我运行以下命令时，会得到以下错误：

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0BSQL文件。

命令：mysqladmin -u root -p status (我输入了密码)

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" 

产出:无

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 (我的中型、小型和大型之间有什么区别)？

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。

命令：mysql.server start (不过，如果我的WP站点正常工作，这不是已经在运行了吗？)

输出：-bash: mysql.server: command not found

我四处打听了一下，偶然发现了MariaDB关于2002年错误的文档，但我似乎没有相同的.conf文件(我也不知道该在哪里查找)

...from --我不知道该去哪里，我只通过shell进行了有限的数据库管理。

简明问题：

1. 如何在不获取2002年误差的情况下导出数据库？
2. 如何覆盖/更新我的数据库？

任何帮助都将是非常感谢和预先感谢！

比塔尼的人来了。我接错主机了。

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

出口：

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