Java拒絕在低特權用戶的Linux下啓動（以root身份正常工作）

雖然如根：

[email protected] [~]# uname -a 
Linux web01 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux` 

[email protected] [~]# java -version 
java version "1.6.0_27" 
Java(TM) SE Runtime Environment (build 1.6.0_27-b07) 
Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)

雖然作爲低特權用戶：

[email protected] [~]# java -Xmx32m -version 
Error occurred during initialization of VM 
Could not reserve enough space for object heap 
Could not create the Java virtual machine.

更新：的的ulimit -a（

輸出時作爲低特權運行用戶）：

core file size   (blocks, -c) 200000 
data seg size   (kbytes, -d) 200000 
scheduling priority    (-e) 0 
file size    (blocks, -f) unlimited

「ulimit -a」的輸出是什麼？ –

您是否曾嘗試以root和非root身份運行_same_命令？ – Mat

@Paul新增了ulimit的輸出。 – Yon

virtual memory   (kbytes, -v) 200000

這是你的罪魁禍首。 Java虛擬機具有32M堆不適合成：

 
$ java -version 
java version "1.6.0_22" 
OpenJDK Runtime Environment (IcedTea6 1.10.3) (fedora-59.1.10.3.fc15-x86_64) 
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode) 
$ ulimit -v 200000 
$ java -version 
Error occurred during initialization of VM 
Could not reserve enough space for object heap 
Could not create the Java virtual machine.

這是我們得到的root用戶：虛擬內存（千字節，-v）無限制爲什麼會有區別？在哪裏配置？ – Yon

添加以下行/etc/security/limits.conf文件

<user> soft as unlimited 
<user> hard as unlimited

你的Linux用戶更換<user>。 -as（地址空間）將用於修改虛擬/實際內存。
