我已经使用 Laradock 部署了一个 Laravel 应用程序。
我想指出数据库连接工作正常（用户可以注册、登录等）。
为了备份应用程序，我安装了Spatie 的 Laravel 备份包。
我相应地设置了所有配置变量，如下所示：
配置/备份.php
<?php
return [
'backup' => [
/*
* The name of this application. You can use this name to monitor
* the backups.
*/
'name' => env('APP_NAME', 'laravel-backup'),
'source' => [
/*......*/
/*
* The names of the connections to the databases that should be backed up
* MySQL, PostgreSQL, SQLite and Mongo databases are supported.
*
* The content of the database dump may be customized for each connection
* by adding a 'dump' key to the connection settings in config/database.php.
* E.g.
* 'mysql' => [
* ...
* 'dump' => [
* 'excludeTables' => [
* 'table_to_exclude_from_backup',
* 'another_table_to_exclude'
* ]
* ],
* ],
*
* If you are using only InnoDB tables on a MySQL server, you can
* also supply the useSingleTransaction option to avoid table locking.
*
* E.g.
* 'mysql' => [
* ...
* 'dump' => [
* 'useSingleTransaction' => true,
* ],
* ],
*
* For a complete list of available customization options, see https://github.com/spatie/db-dumper
*/
'databases' => [
'mysql',
],
],
/*
* The database dump can be compressed to decrease diskspace usage.
*
* Out of the box Laravel-backup supplies
* Spatie\DbDumper\Compressors\GzipCompressor::class.
*
* You can also create custom compressor. More info on that here:
* https://github.com/spatie/db-dumper#using-compression
*
* If you do not want any compressor at all, set it to null.
*/
'database_dump_compressor' => null,
/*....*/
],
],
];
在 Laravel Homestead 中，备份工作正常。
$ php artisan backup:run.
根据这个包的文档，我们需要指定mysqldump二进制文件的路径，如下所示：
配置/数据库.php
//config/database.php
'connections' => [
'mysql' => [
'driver' => 'mysql'
...,
'dump' => [
'dump_binary_path' => '/path/to/the/binary', // only the path, so without `mysqldump` or `pg_dump`
'use_single_transaction',
'timeout' => 60 * 5, // 5 minute timeout
'exclude_tables' => ['table1', 'table2'],
'add_extra_option' => '--optionname=optionvalue',
]
],
这是我在同一个文件中默认得到的：
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
'dump'=>[
'dump_binary_path' => env('DB_DUMP_PATH'), // only the path, so without `mysqldump` or `pg_dump`
'use_single_transaction',
'timeout' => 60 * 5, // 5 minute timeout
//'exclude_tables' => ['table1', 'table2'],
//'add_extra_option' => '--optionname=optionvalue',
'add_extra_option' => '--host='.env('DB_HOST'),
]
],
在我的.env文件中：
DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DUMP_PATH='/usr/bin/'
如果我mysqldump在 MySQL 容器内部执行，它确实有效：
Usage: mysqldump [OPTIONS] database [tables]
OR mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...]
OR mysqldump [OPTIONS] --all-databases [OPTIONS]
For more options, use mysqldump --help
但是，如果我在工作空间容器中运行备份命令，
artisan backup:run
我得到错误：
备份失败，因为：转储过程失败，退出代码 127：找不到命令：sh：1：mysqldump：未找到
那我怎么告诉 Laradock mysqldump 二进制路径在哪里呢？
有解决方法吗？也许设置一个与容器连接的新Workspace容器MySQL？
任何替代方法？
在 Adrien
Right的帮助下解决.env文件，我确实发现以下变量设置为 false：
### WORKSPACE #############################################
####
# ...
WORKSPACE_INSTALL_MYSQL_CLIENT=false
# ...
所以我把它改成了真的：
### WORKSPACE #############################################
####
# ...
WORKSPACE_INSTALL_MYSQL_CLIENT=true
# ...
我保存并退出。
这也意味着我不必对docker-compose.custom.yml文件进行任何更改
为了应用该更改，我执行了（无需停止任何容器）
$ docker-compose build workspace
$ docker-compose -f docker-compose.custom.yml up -d workspace
然后我进入了容器
$ docker exec -it my_workspace bash
进去后，我寻找 mysqldump：
# which mysqldump
/usr/bin/mysqldump
最后我可以执行 Spatie 的 Laravel 备份包：
# artisan backup:run
Starting backup...
Dumping database xyz...
Determining files to backup...
Zipping x files and directories...
Created zip containing x files and directories. Size is x.x MB
Copying zip to disk named backMeUp...
Successfully copied zip to disk named backMeUp.
Backup completed!
这就是诀窍！
