尽管 chmod 777，java.io.FileNotFoundException(权限被拒绝) [英] java.io.FileNotFoundException (permission denied) despite chmod 777

问题描述

我在编写部署在 Tomcat 上的 Grails 应用程序时遇到了奇怪的问题.

I have faced strange poblem while writing Grails application deployed on Tomcat.

创建简单的测试控制器后，我想在其中编写测试内容包com

After creating simple test controller I want to write test contents in package com

package com.domain.controller

import java.io.File;
import java.io.PrintWriter;

class TestController {

        def index() {
                // test
                try {
                        PrintWriter writer = new PrintWriter("/home/user/domains/domain.com/public_html/the-file-name.txt");
                        writer.println("The first line");
                        writer.println("The second line");
                        writer.close();
                } catch (IOException e) {
                        throw new RuntimeException(e);
                }
        }
}

我得到一个例外:

类 java.io.FileNotFoundException 消息/home/user/domains/domain.com/public_html/the-file-name.txt (Brakdostępu)

Class java.io.FileNotFoundException Message /home/user/domains/domain.com/public_html/the-file-name.txt (Brak dostępu)

我已将 chmod 设置为 777 到 /home/user/domains/domain.com/public_html/.而 tomcat7.tomcat7 是所有者.我也尝试使用访问权限 777 和设置为 tomcat7 的所有权创建此文件，但我仍然遇到异常:

I have set the chmod to 777 into /home/user/domains/domain.com/public_html/. And tomcat7.tomcat7 is owner. I have also tried to create this file with the access rights 777 and ownership set to tomcat7, but I still get an exception:

ls -al /home/user/domains/domain.com/public_html
razem 16
drwxrwxrwx 3 tomcat7 tomcat7 4096 01-08 23:25 .
drwxr-xr-x 8 user    user    4096 12-16 17:14 ..
-rwxrwxrwx 1 tomcat7 tomcat7    0 01-08 23:25 the-file-name.txt

我还应该满足操作系统中的哪些条件?

What conditions in OS should I also meet?

如果有人能澄清问题，我将不胜感激.

I would be very gratefull if someone could clarify the problem.

编辑:

我在/path1下创建了目录，设置为777.文件保存完好.我也在 /path2/testdir 下创建了目录，但是 path2 没有权限 777 和 chown.它也有效.我还测试了带有字符 . 和 _ 的 testdir，也可以使用.

I have created the directory under /path1, set 777. The files are stored perfectly. I have also crated the directory under under /path2/testdir, but path2 has no permission 777 and chown. It also works. I have also testes the testdir with characters . and _, also works.

我非常善于调查，无法理解这种行为.

I am very investigative and cannot understand the behaviour.

推荐答案

确保您也拥有对所有父目录的读取和执行权限.

Ensure you that you have read and execute access to all parent directories as well.

示例:chmod o+x/home/user
