Graphite SQLite3 DatabaseError：尝试写入只读数据库

在 apache httpd 下运行 graphite，使用 slqite 数据库，我拥有正确的文件夹权限

[root@liaan55 httpd]# ls -ltr /var/lib | grep graphite
drwxr-xr-x. 2 apache        apache        4096 Aug 23 19:36 graphite-web

和

[root@liaan55 httpd]# ls -ltr /var/lib/graphite-web/
total 68
-rw-r--r--. 1 apache apache 65536 Aug 23 19:46 graphite.db

syncdb 似乎也运行正常

[root@liaan55 httpd]# sudo -su apache
bash-4.1$ whoami

You just installed Django's auth system, which means you don't have any superusers defined.
Would you like to create one now? (yes/no): yes
Username (leave blank to use 'apache'): root

local-settings.py 文件如下

STORAGE_DIR = '/var/lib/graphite-web'

INDEX_FILE = '/var/lib/graphite-web/index' 

DATABASES = {
    'default': {
        'NAME': '/var/lib/graphite-web/graphite.db',
        'ENGINE': 'django.db.backends.sqlite3',
        'USER': '',
        'PASSWORD': '',
        'HOST': '',
        'PORT': ''
    }
}

我仍然收到此错误

[Sat Aug 23 19:47:17 2014] [error] [client 10.42.33.238]   File "/usr/lib/python2.6/site-packages/django/db/backends/sqlite3/base.py", line 344, in execute

[Sat Aug 23 19:47:17 2014] [error] [client 10.42.33.238] DatabaseError: attempt to write a readonly database

不确定此配置中缺少什么

答案1

检查了父级（即 ）的所有者和组/var/lib/graphite。结果发现两者都是 ，_graphite而不是apache。将所有者和组更改为_graphite并重新启动apache2：

user@host:~$ sudo chown _graphite:_graphite /var/lib/graphite/graphite.db 
user@host:~$ sudo service apache2 restart

解决了 Ubuntu Xenial 上的问题。

答案2

来自石墨安装文件：

如果您在访问数据库文件时遇到问题，则可能需要将数据库文件的所有权更改为拥有 Apache 进程的同一用户。如果您的发行版以用户“nobody”的身份运行 apache：

sudo chown nobody：nobody /opt/graphite/storage/graphite.db

就我而言，由于我在 CentOS 上使用 Graphite 的 RPM 安装，因此 graphite.db 文件位于此处：

-rw-r--r-- 1 apache apache 69632 Sep 30 08:02 /var/lib/graphite-web/graphite.db
