Debian Jessie에 MySQL 설치 (8)

저는 Linux를 처음 사용합니다. Debian Jessie(8) 운영 체제를 새로 설치했고 MySQL을 사용해야 합니다. 호스트 이름은

hostname -f

그것은 인쇄됩니다,debian8

터미널에 입력하면,

sudo dpkg --get-selections | grep mysql

나는 출력을 얻습니다.

libdbd-mysql-perl               install
libmysqlclient18:amd64              install
mysql-client-5.5                install
mysql-common                    install
mysql-server                    install
mysql-server-5.5                install
mysql-server-core-5.5               install
php5-mysql                  install

터미널에 입력하면,

sudo apt-cache show mysql

출력은,

N: Unable to locate package mysql
E: No packages found
chaklader@debian8:/home/cx-components$ 

터미널에 입력하면,

locate mysql

출력은,

/usr/lib/libreoffice/program/libmysqllo.so

/usr/share/bash-completion/completions/mysqladmin

/usr/share/nmap/scripts/mysql-vuln-cve2012-2122.nse

터미널에 입력하면, which mysql

출력이 없습니다.

터미널에 입력하면,

mysql -u root -p

출력은,

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

운영 체제에 MySQL이 설치되어 있습니까? 그렇지 않은 경우 어떻게 설치합니까?

고쳐 쓰다:

제안된 대로 MySQL 서버가 시작되지 않습니다. 그래서 다음 명령을 사용하여 서버를 시작했습니다.

sudo /etc/init.d/mysql start

출력은 다음과 같습니다.

[....] Starting mysql (via systemctl): mysql.service
Job for mysql.service failed. See 'systemctl status mysql.service' and 'journalctl -xn' for details.
 failed!

관련 명령에 대한 자세한 정보를 찾아보는 것이 좋습니다. 이는 잘못된 정보입니다.

터미널에 입력하고,

sudo systemctl status mysql.service

제공된 출력을 얻었습니다.

둘째, 아래 제공된 명령을 입력합니다 journalctl.

sudo journalctl -xn

출력은,

따라서 기본적으로 가장 먼저 해야 할 일은 MySQL 서버를 올바르게 실행하는 것입니다.

서버도 운영해봤는데,

sudo systemctl start mysql.serivce

제공된 출력은 다음과 같습니다.

Failed to start mysql.serivce.service: Unit mysql.serivce.service failed to load: No such file or directory.

이를 위해서는 어떤 조치를 취해야 합니까?

Note:

댓글에서 요청한대로 명령을 실행하면

sudo systemctl status mysql.service -l

내가 얻는 결과는 다음과 같습니다.

● mysql.service - LSB: Start and stop the mysql database server daemon
   Loaded: loaded (/etc/init.d/mysql)

제가 주로 해야 할 일은 다음 명령을 사용하여 데이터베이스를 마이그레이션하는 것입니다.

/home/cx-components/cx-admin/app/console doctrine:migrations:migrate

내가 얻는 결과는 다음과 같습니다.

                    Application Migrations                    

  [PDOException]

doctrine:migrations:migrate [--write-sql] [--dry-run] [--query-time] [--configuration[="..."]] [--db-configuration[="..."]] [--db="..."] [--em="..."] [version]

여기서 문제가 무엇입니까?

댓글에서 언급한 대로 오타를 수정하고 다시 sudo systemctl start mysql.service 명령을 실행했습니다.

출력은 여기로 이동합니다.

Job for mysql.service failed. See 'systemctl status mysql.service' and 'journalctl -xn' for details.
