不能运行任何shell脚本，即使是root

Question

当尝试在新租的VPS上运行teamspeak服务器和minecraft服务器时，我遇到了一些大麻烦。每当我尝试运行shell脚本时，即使在root下它也不起作用。

一个脚本:spigot.sh

#!/bin/sh
BINDIR=$(dirname "$(readlink -fn "$0")")
cd "$BINDIR"
java -Xms5G -Xmx7G -XX:MaxPermSize=128M -jar spigot.jar

尝试将此作为根

后出现错误

root@vps23946:/home/user/minecraft# ./spigot.sh
-bash: ./spigot.sh: Permission denied

尝试使用此用户

后出现错误

user@vps23946:~/minecraft$ ./spigot.sh
-bash: ./spigot.sh: Permission denied

ls -l

结果

root@vps23946:/home/user/minecraft# ls -l
total 22616

第二个脚本:ts3server_minimal_runscript.sh#！/bin/sh

export LD_LIBRARY_PATH=".:$LD_LIBRARY_PATH"
D1=$(readlink -f "$0")
D2=$(dirname "${D1}")
cd "${D2}"
if [ -e ts3server_linux_x86 ]; then
    if [ -z "`uname | grep Linux`" -o ! -z "`uname -m | grep 64`" ]; then
            echo "Do you have the right TS3 Server package for your system? You have:        `    uname` `uname -m`, not Linux i386."
    fi
    ./ts3server_linux_x86 $@
elif [ -e ts3server_linux_amd64 ]; then
    if [ -z "`uname | grep Linux`" -o -z "`uname -m | grep 64`" ]; then
            echo "Do you have the right TS3 Server package for your system? You have: `  uname` `uname -m`, not Linux x86_64."
    fi
    ./ts3server_linux_amd64 $@
elif [ -e ts3server_freebsd_x86 ]; then
    if [ ! -z "`uname | grep Linux`" -o ! -z "`uname -m | grep 64`" ]; then

用这些我得到相同的错误。

我正在运行Ubuntu Server 14.04

Answer 1

脚本和程序必须是可执行的才能按名称调用。或者使用chmod为文件添加可执行权限(chmod a+x ./spigot.sh)，或者调用可执行解释器并传入脚本，例如/bin/sh ./spigot.sh

Answer 2

Try

 chmod +x spigot.sh

，这将使脚本能够执行
