Em uma nova instalação do Kubuntu 14.04, eu corri sudo aptitude install mysql-server-core-5.6
. A instalação não pôde ser concluída devido às dependências de alguns pacotes do KDE mysql-server-core-5.5
, que teriam sido substituídos. Agora, quando executo sudo aptitude install mysql-server-5.5
, recebo este erro após especificar uma senha:
Configuring mysql-server-5.5
Unable to set password for the MySQL "root" user
An error occurred while setting the password for the MySQL administrative user. This may have happened
because the account already has a password, or because of a communication problem with the MySQL server.
You should check the account's password after the package installation.
Please read the /usr/share/doc/mysql-server-5.5/README.Debian file for more information.
De fato, li, /usr/share/doc/mysql-server-5.5/README.Debian
mas não havia nada relevante para a minha situação. O log do MySQL ajuda:
$ tail /var/log/mysql/error.log

140818 10:17:18 [Note]
No entanto, não consigo encontrar em qual script a --explicit_defaults_for_timestamp
opção está definida. Tentei começar mysql
sem service
evitar a --explicit_defaults_for_timestamp
opção, mas ela ainda não inicia:
$ ps aux | grep mysql
dotanco+ 25458 0.0 0.0 11748 928 pts/4 S+ 10:30 0:00 grep --color=auto mysql

140818 10:30:54 mysqld_safe Can't log to error log and syslog at the same time. Remove all --log-error configuration options for --syslog to take effect.

$ ps aux | grep mysql
dotanco+ 25810 0.0 0.0 11748 932 pts/4 S+ 10:31 0:00 grep --color=auto mysql
O erro me diz para Remove all --log-error configuration options
. Portanto, editei /etc/mysql/my.cnf
e comentei a seguinte linha:
log-error = /var/log/mysql/error.log
Agora não recebo nenhum erro, mas ainda não consigo fazer login:
$ sudo mysqld_safe --skip-grant-tables &

$ mysql -uroot
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Qual pode ser o problema? Como devo proceder?
EDITAR
Eu já comentei a explicit-defaults-for-timestamp
linha my.cnf
. Aqui está o arquivo inteiro, menos os comentários do cabeçalho:
$ cat /etc/mysql/my.cnf
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
[mysqld_safe]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
nice = 0
[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
#explicit_defaults_for_timestamp
bind-address = 127.0.0.1
#log-error = /var/log/mysql/error.log
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
symbolic-links=0
!includedir /etc/mysql/conf.d/
É o que acontece quando tento executar o MySQL:
$ sudo echo 1 >> /var/log/mysql/error.log
$ tail /var/log/mysql/error.log

Como pode ser visto, nada de novo é gravado nos logs e a explicit_defaults_for_timestamp
opção não é definida em nenhum lugar.
Consegui reinstalar, mysql-server-core-5.5

Isso 1

e indica que nada de novo foi adicionado ao log.
timestamp
foi encontrada apenas em etc/mysql/my.cnf
e eu a comentei. No entanto, ainda recebo a mesma menção no log.
