Клиент моей ИТ-консалтинговой службы владеет магазином веб-разработки. У него было проблемы с сервером Slackware 12.0 с MySQL 5.0.67. Машина была настроена сисадмином клиента, который ушел в плохих условиях. Мой клиент больше не использует системного администратора.
Насколько я могу судить, единственная установленная копия MySQL - это та, которая описана в /var/log/packages/mysql-5.0.67-i486-1:
PACKAGE NAME: mysql-5.0.67-i486-1
COMPRESSED PACKAGE SIZE: 16828 K
UNCOMPRESSED PACKAGE SIZE: 33840 K
PACKAGE LOCATION: /var/slapt-get/archives/./slackware/ap/mysql-5.0.67-i486-1.tgz
PACKAGE DESCRIPTION:
mysql: mysql (SQL-based relational database server)
mysql:
mysql: MySQL is a fast, multi-threaded, multi-user, and robust SQL
mysql: (Structured Query Language) database server. It comes with a nice API
mysql: which makes it easy to integrate into other applications.

# Description: MySQL is a very fast and reliable SQL database engine.
### END INIT INFO
# If you install MySQL on some other places than /usr, then you
# have to do one of the following things for this script to work:
#
# - Run this script from within the MySQL installation directory
# - Create a /etc/my.cnf file with the following information:
# [mysqld]
# basedir=<path-to-mysql-installation-directory>
# - Add the above to any other configuration file (for example ~/.my.ini)
# and copy my_print_defaults to /usr/bin
# - Add the path to the mysql-installation-directory to the basedir variable
# below.
#
# If you want to affect other MySQL variables, you should make your changes
# in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.
# If you change base dir, you must also change datadir. These may get
# overwritten by settings in the MySQL configuration files.

#datadir=

Неважно: предыдущие пользователи машины хранили беспорядочный домашний каталог. Их домашний каталог был /root. Я вставил копию в http://www.pastebin.ca/2167496.
Мой вопрос:
Какое ваше лучшее предположение относительно того, почему существует /etc/init.d/mysql файл на этой машине Slackware? Как файл мог попасть туда?
P.S. Этот вопрос далек от совершенства. Пожалуйста, не стесняйтесь редактировать его.
На твой вопрос невозможно ответить. Возможно, предыдущий администратор установил MySQL каким-то другим способом, кроме официального? Возможно, он просто поискал в Google сценарий инициализации и вручную скопировал его в /etc/init.d?
Невозможно узнать, что произошло, если у вас нет каких-либо журналов аудита.
Насколько я знаю, у всех демонов есть собственный файл в /etc/init.d. В основном все файлы, которые там есть, запускаются при загрузке и останавливаются при выключении.
