我有一只tomcat在弹性豆茎EC2:上运行
64位Amazon Linux 2015.09 v2.0.4运行Tomcat 8 Java 8
当web应用程序想要创建新目录/文件时，我遇到了问题。我在catalina.out 中收到以下错误
java.io.IOException: java.io.FileNotFoundException: /home/ec2-user/images/companydata/images/2/10/ac3feab8-a2db-4052-9614-eea41c0a509e.png (Permission denied)

所以，我知道这是一个权限问题，所以我在谷歌上搜索了一下，找到了如何通过键入来找出用户启动tomcat的方法
[root@ip-172-31-1-99 tomcat8]# ps auxwww | grep -v grep | grep tomcat

我可以看到tomcat是由用户tomcat启动的。
因此，我更改了我想存储所有详细信息的根文件夹，并将chown提供给用户tomcat和组tomcat，以及上的chmod 777
/主页/ec2用户/图像/
drwxrwxrwx 2 tomcat tomcat 4096 1月5日19:40图像
但我得到了同样的权限拒绝错误。
方法如下：
String StoreImageHere =
locationOfCompanyData
+ File.separator
+ locationOfImage
+ File.separator
+ user.getCompany_id()
+ File.separator +
+ notUpdatedImage.getServer_questionnaire_attempt_key()
+ File.separator ;
File uploadedFileFolderLocation = new File(locationRoot, StoreImageHere);
uploadedFileFolderLocation.mkdirs();
String storeImageName = StoreImageHere + notUpdatedImage.getImage_name();
File uploadedFile = new File(locationRoot, storeImageName);
try {
file.transferTo(uploadedFile);
} catch (IllegalStateException e) {
e.printStackTrace();
logger.error(user.getUsers_email()
+ " /api/mobile/uploadImage/{server_image_id}/ "
+ " userID[" + user.getUsers_id() + "]"
+ " error[" + e.getMessage() + "]");
} catch (IOException e) {
e.printStackTrace();
logger.error(user.getUsers_email()
+ " /api/mobile/uploadImage/{server_image_id}/ "
+ " userID[" + user.getUsers_id() + "]"
+ " error[" + e.getMessage() + "]");
}
if(uploadedFile.exists()) {
notUpdatedImage.setSync(ENUM_SYNC_STATUS.SYNCED.getValue());
notUpdatedImage = mobileManagment.updateImage(user, notUpdatedImage, ENUM_ACTIVITY_TYPE.ANSWER_INPUT_UPLOADED);
return new Gson().toJson(notUpdatedImage);
} else {
logger.error(user.getUsers_email()
+ " /api/mobile/"+VERSION+"/uploadImage/{server_image_id}/ "
+ " userID[" + user.getUsers_id() + "]"
+ " dest.exists() == false ");
}
我运行
设置强制0
它返回
setenforce:SELinux已禁用
在windows机器上，它采用这个参数
location.server.root=C:/Users/killesk_bouse/Desktop/temp/
在linux机器上，它需要这个
location.server.root=/home/ec2用户/images/
除非有一个简单的错误，我只是没有看到
您可能仍然存在权限问题。为了能够浏览/home/ec2 user/images，您的"tomcat"用户需要在所有上层目录（即home和ec2 user）上都有"x"。您可能可以通过更改这些目录的模式以允许其他组执行它们来解决您的问题：
chmod o+x /home
chmod o+x /home/ec2-user
尽管如此，您不应该在敏感系统上这样做。您可能想尝试在适当的目录中进行写和读操作。
如果它不能解决您的问题，那么您的问题可能与SELinux有关。
您可以尝试以下命令进行检查：
setenforce 0
