В течение последних 3 недель моя 10-летняя дочь умоляла меня построить свой сервер minecraft/bukkit, и я пытаюсь сделать это на моем VPS-сервере Centos6.4. Я следую за https://forums.bukkit.org/threads/tutorial-centos-bukkit-installation.56371/, за исключением того, что вместо JDK-7u2 я установил Oracle Java JDK-7u45. У меня есть обычный пользователь под названием "Minecraft", где я пытаюсь запустить службу под.
На шаге 6 описывается создание /etc/init.d/minecraft
которое я сделал (скрипт продублирован ниже). Я предполагаю, что владелец файла должен быть "minecraft", а не "root", если я хочу, чтобы служба запускалась как пользователь "minecraft", правильно?
На шаге 10 показано, как запустить сервис, запустив service minecraft start
. При этом я получаю следующее. Есть предложения почему?
[minecraft@vps ~]$ service minecraft start
craftbukkit.jar was not running... starting.
Could not start craftbukkit.jar.
[minecraft@vps ~]$ su
Password:
[root@vps minecraft]# service minecraft start
craftbukkit.jar was not running... starting.
Could not start craftbukkit.jar.
[root@vps minecraft]#
РЕДАКТИРОВАТЬ. Нужно ли заменить craftbukkit.jar
на полное имя craftbukkit-1.6.4-R1.0.jar
в одной из двух строк файла /etc/init.d/minecraft
? Кроме того, нужно ли изменить вторую строку в отношении конфигурации Java?
