Estou usando o Symfony 4 e a versão Mysql é 8.0.11 e usando um usuário em vez de um login root e quando tento usar o comando php bin/console make:migration i recebo este erro:
In AbstractMySQLDriver.php line 126:
An exception occurred in driver: SQLSTATE[HY000] [2006] MySQL server has gone away
In PDOConnection.php line 50:
SQLSTATE[HY000] [2006] MySQL server has gone away

SQLSTATE[HY000] [2006] MySQL server has gone away
In PDOConnection.php line 46:
PDO::__construct(): Unexpected server respose while doing caching_sha2 auth: 109
Então eu tentei pesquisar on-line e descobri que algo deu errado com as variáveis do MySQL wait_timeout e max_allowed_packet e tive que alterar essas variáveis no arquivo /etc/mysql/my.cnf , o problema é quando eu vou editar esse arquivo Eu só acho isso:

!includedir /etc/mysql/mysql.conf.d/
então eu tentei ver um tópico chamado " Por que é / etc / mysql / my.cnf EMPTY? "e um usuário disse para usar um destes caminhos:
/etc/mysql/conf.d/
/etc/mysql/mysql.conf.d/
/etc/mysql/mysql.conf.d/mysqld.cnf
e então eu tentei ...

e em qualquer um desses arquivos eu não consegui encontrar as variáveis do MySQL wait_timeout e max_allowed_packet , então obrigado antecipadamente se alguém pudesse me ajudar com este problema. :)
P.S: (eu já executei este comando php bin/console make:migration várias vezes antes desse erro e também criei bancos de dados e correu bem, então parece que não é um problema de instalação).
Atualização: parece que as variáveis wait_timeout e max_allowed_packet foram alteradas globalmente, adicionando aos três arquivos os seguintes
max_allowed_packet=1024M
wait_timeout=3000000
e, em seguida, usando este comando sudo service mysql restart
me dando isso:
mysql> SHOW global VARIABLES LIKE "wait_timeout";
+---------------+---------+
| Variable_name | Value |
+---------------+---------+
| wait_timeout | 3000000 |
+---------------+---------+
1 row in set (0,00 sec)
mysql> SHOW VARIABLES like 'max_allowed_packet';
+--------------------+------------+
| Variable_name | Value |
+--------------------+------------+
| max_allowed_packet | 1073741824 |
+--------------------+------------+
1 row in set (0,00 sec)
mas ainda quando tentei usar esse comando php bin/console make:migration me deu o mesmo erro que mencionei acima neste post, também tentei alterar a variável wait_timeout para 300 pelo mesmo método e me deu o mesmo resultado. : (
usando este comando sudo vim /var/log/mysql/error.log i obter isto:

Atualização: Eu desintalled mysql e php e mudei para o mysql 5.7 e php 7.2.7, a mudança do php pode ter resolvido de acordo com link o usuário @jibe, se alguém ainda não conseguir resolver o problema eu deixo esses dois outros links link 1 e link2 .
Eu sei que já faz um tempo, mas encontrei a resposta. Use o seguinte comando para atualizar sua senha com o novo plugin de autenticação. Você pode usar o MySQL 8 agora. Divirta-se.
ALTER USER 'username'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'password';
OR
ALTER USER 'username'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
