MySQL - Erro 1045: Access denied for user: 'root@localhost'
Olá pessoal do VOL.
Tive muitos problemas com esta propriedade do MySQL, pois, por padrão após sua instalação, vem com sua senha desconfigurada.
De início, consigo logar normalmente, porém, depois de algum tempo ele começa a dar o seguinte erro:
Bom, para resolvermos isso, primeiramente temos que alterar a senha de root do MySQL:
1. Pare o MySQL:
# /etc/init.d/mysql stop
2. Iniciei o MySQL, sem senha:
# mysqld_safe --skip-grant-tables
3. Conecte ao MySQL, usando:
mysql client - mysql -u root
4. No prompt do MySQL, execute:
mysql> use mysql
mysql> update user set password=PASSWORD("coloque-sua-nova-senha-de-root") where User='root';
mysql> flush privileges;
mysql> quit
5. Pare novamente o MySQL:
# /etc/init.d/mysql stop
6. Iniciei novamente o MySQL:
# /etc/init.d/mysql start
7. Faça o teste:
mysql -u root -p
Bom, fazendo estes procedimentos, sua nova senha de root para o banco de dados estará configurada.
Mas, se tentar acessar sem senha, acontecerá o mesmo erro:
mysql -u root -p
2. Execute o comando abaixo:
mysql> set password for root@localhost=password('');
3. Tente entrar sem a senha no banco de dados, digite:
mysql
Espero ter ajudado pessoal. (:

1. Entre novamente com no MySQL com a senha que setamos anteriormente:mysql -u root -p
2. Execute o comando abaixo:
mysql> set password for root@localhost=password('');
3. Tente entrar sem a senha no banco de dados, digite:
mysql

Se você esta usando esse MySQL somente internamente, sem acesso externo beleza, mas deixar sem senha eu acho um tanto quanto arriscado.

Darlan, acho que deu erro pra mim
pois ao dar o comando

apareceu

no comando mysqld_safe --skip-grant-tables
dá o seguinte:
140226 15:58:50 mysqld_safe Logging to syslog.
140226 15:58:50 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
dai fica assim, como se tivesse iniciando mas sem dá nenhum sinal. Demora muito mesmo ou isso não é assim?

Também estou com o mesmo com o mesmo erro reportado pelo nikaway.
No meu caso fica aparecendo esse erro todos os dias independente de ter alguém logado no banco ou não.

Pessoal, sobre isso eu realizei os seguintes passos (gambiarra, não sei o porque de ter funcionado).
Quando aparece a mensagem "131007 20:07:30 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql" e fica parado, eu fechei o terminal e abri novamente, realizei o passo 3 "$ mysql client - mysql -u root". logo apos eu digitei "$ mysql -i", e voltei a realizar o tutorial a partir do passo 4.
Não sei explicar porque funcionou. Espero ter ajudado :)

Isso provavelmente esta ocorrendo por que vc tem duas instancias rodando, e isso não pode ocorrer:
error log and syslog at the same time
Pare o Mysql(dependendo a sua versão de SO):
/etc/init.d/mysql stop
systemctl stop mysql
Valide que esteja(Se voltar um numero(pid) é pq ainda esta rodando)
pgrep mysql
Mate ele:
kill $(pgrep mysql)
ou(só se necessario)
kill -9 $(pgrep mysql)
Ai siga o procedimento....
Caso mesmo trocando a senha ainda tenha o erro:
Ao invés disso:
update user set password=PASSWORD("coloque-sua-nova-senha-de-root") where User='root';
Faça isso:
UPDATE user SET Password=password('xyz') WHERE User='root'; FLUSH PRIVILEGES; exit;
Para Mysql/MariaDB(validando como informei)
Inicie e pronto...

Usage: mysql [OPTIONS] [database]
-?, --help Display this help and exit.
-I, --help Synonym for -?
--auto-rehash Enable automatic rehashing. One doesn't need to use

and reconnecting may take a longer time. Disable with
--disable-auto-rehash.
(Defaults to on; use --skip-auto-rehash to disable.)
-A, --no-auto-rehash
No automatic rehashing. One has to use 'rehash' to get
table and field completion. This gives a quicker start of
mysql and disables rehashing on reconnect.
--auto-vertical-output
Automatically switch to vertical output mode if the
result is wider than the terminal width.
-B, --batch Don't use history file. Disable interactive behavior.
(Enables --silent.)
--bind-address=name IP address to bind to.
--binary-as-hex Print binary data as hex
--character-sets-dir=name
Directory for character set files.

--histignore=name A colon-separated list of patterns to keep statements
from getting logged into syslog and mysql history.
-G, --named-commands

option, the default pager is taken from your ENV variable
PAGER. Valid pagers are less, more, cat [> filename],
etc. See interactive help (\h) also. This option does not
work in batch mode. Disable with --disable-pager. This
option is disabled by default.
-p, --password[=name]
Password to use when connecting to server. If password is
not given it's asked from the tty.
-P, --port=# Port number to use for connection or 0 for default to, in
order of preference, my.cnf, $MYSQL_TCP_PORT,

--plugin-dir=name Directory for client-side plugins.
--default-auth=name Default authentication client-side plugin to use.
--binary-mode By default, ASCII '\0' is disallowed and '\r\n' is
translated to '\n'. This switch turns off both features,

piped to mysql or loaded using the 'source' command).
This is necessary when processing output from mysqlbinlog
that may contain blobs.
--connect-expired-password

expired password sandbox mode.
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf

--max-allowed-packet=#
The maximum packet length to send to or receive from
server.

(pre-4.1.1) protocol. Deprecated. Always TRUE
--server-arg=name Send embedded server this as a parameter.
--show-warnings Show warnings after every statement.

commands depends on the patterns supplied via histignore
option besides the default patterns.
--plugin-dir=name Directory for client-side plugins.
--default-auth=name Default authentication client-side plugin to use.
--binary-mode By default, ASCII '\0' is disallowed and '\r\n' is
translated to '\n'. This switch turns off both features,
and also turns off parsing of all clientcommands except
\C and DELIMITER, in non-interactive mode (for input
piped to mysql or loaded using the 'source' command).
This is necessary when processing output from mysqlbinlog
that may contain blobs.
--connect-expired-password
Notify the server that this client is prepared to handle
expired password sandbox mode.

/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
