創建文件夾時系統權限被拒絕
我正在嘗試安裝InfluxDB 2.0並按照此處的說明進行操作
Centos 7
。所以,我的服務文件是:/lib/systemd/system/influxdb.service
及其內容:[Unit] Description=InfluxDB 2.0 service file. Documentation=https://v2.docs.influxdata.com/v2.0/get-started/ After=network-online.target [Service] User=influxdb Group=influxdb ExecStart=/usr/local/bin/influxd Restart=on-failure [Install] WantedBy=multi-user.target
並
ls
輸入文件:[vagrant@localhost ~]$ ls /lib/systemd/system/inf* -l -rw-r--r--. 1 root root 268 Oct 17 09:54 /lib/systemd/system/influxdb.service
Influxdb 二進製文件在這裡:
[vagrant@localhost ~]$ ls /usr/local/bin/inf* -l -rwxr-xr-x. 1 influxdb influxdb 33235536 Oct 17 09:46 /usr/local/bin/influx -rwxr-xr-x. 1 influxdb influxdb 95804192 Oct 17 09:46 /usr/local/bin/influxd
Systemd 服務狀態為:
[vagrant@localhost ~]$ systemctl status influxdb.service ● influxdb.service - InfluxDB 2.0 service file.

但是,該服務無法正常工作並且正在尋找
sudo journalctl | grep influxdb | less

根據上面的日誌,創建文件夾失敗。我執行了這個:
sudo mkhomedir_helper influxdb
創建主文件夾influxdb
,檢查權限的結果是這樣的:[vagrant@localhost ~]$ sudo ls -l /home total 0 drwxr-xr-x. 4 influxdb influxdb 95 Oct 17 11:39 influxdb drwx------. 4 vagrant vagrant 109 Oct 17 11:54 vagrant
我無法弄清楚我缺少給使用者(創建的:)足夠的權限以
sudo useradd -rs /bin/false influxdb
將二進製文件作為服務執行?更新:添加了審核日誌

幫助?謝謝
直到昨天我遇到一個類似的問題並將其追溯到 SELinux 時,我才確定這個問題。
InfluxDB 沒有 SELinux 策略,Red Hat 既不提供也不包含在 InfluxDB 本身中。此類服務在通用策略下執行,除其他外,該策略禁止服務訪問
/home
,因為系統服務應將其文件放置在其他地方。嘗試將 InfluxDB 主目錄
/home/influxdb
從/var/lib/influxdb
. 你可以這樣做:
- 執行
sudo mv /home/influxdb /var/lib/influxdb
以移動文件。- 執行
sudo restorecon -rv /var/lib/influxdb
以修復 SELinux 上下文。- 執行
sudo vipw
以編輯 passwd 文件,並將 influx 使用者的主目錄從/home/influxdb
更改為/var/lib/influxdb
.現在嘗試再次啟動服務。如果它不起作用,您可能還需要重新執行
influx setup
以擺脫任何引用/home
.
