问题描述
我已经在Laradock上部署了Laravel应用程序。
我想指出的是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，我已经安装了Spatie's Laravel Backup package。
我相应地设置了所有配置变量，如下所示：
config / backup.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to this package's docs，我们需要如下指定mysqldump二进制文件的路径：
config / database.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',]
],这是我默认情况下在同一文件中得到的：
'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','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'),so without `mysqldump` or `pg_dump`
'use_single_transaction',// 5 minute timeout
//'exclude_tables' => ['table1',//'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/'
如果我在MySQL容器中执行mysqldump，它将起作用：
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，如果我在工作区容器中运行backup命令，
artisan backup:run
我得到了错误：
备份失败，因为：转储过程失败，退出代码为127： 找不到命令：sh：1：mysqldump：找不到
那我如何告诉Laradock mysqldump二进制路径在哪里？
有解决方法吗？也许要建立一个将Workspace与MySQL容器连接起来的新容器？
还有其他方法吗？
在Adrien的帮助下解决
我确实在.env文件中发现以下变量设置为false：
### WORKSPACE #############################################
####
# ...
WORKSPACE_INSTALL_MYSQL_CLIENT=false
# ...
所以我将其更改为true：
### WORKSPACE #############################################
####
# ...
WORKSPACE_INSTALL_MYSQL_CLIENT=true
# ...
我保存并退出。
这也意味着我不必在docker-compose.custom.yml文件中进行任何更改
要应用该更改，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
一旦我在里面寻找mysqldump：
# which mysqldump
/usr/bin/mysqldump
最后，我可以执行Spatie的Laravel Backup软件包：
# 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!
那就成功了！
