我正在尝试按照概述的说明在运行 Proxmox 的 Alpine Linux LXC 上设置 NFS 服务器这里,但rpc.statd
拒绝启动。以下是/var/log/messages
显示错误的摘录:
Nov 26 03:08:25 nfs daemon.notice rpc.statd[226]: Version 2.1.1 starting
Nov 26 03:08:25 nfs daemon.warn rpc.statd[226]: Flags: TI-RPC
Nov 26 03:08:25 nfs daemon.err rpc.statd[226]: Unable to prune capability 0 from bounding set: Operation not permitted
Nov 26 03:08:25 nfs daemon.err /etc/init.d/rpc.statd[224]: start-stop-daemon: failed to start `/sbin/rpc.statd'
Nov 26 03:08:25 nfs daemon.err /etc/init.d/rpc.statd[210]: ERROR: rpc.statd failed to start
Nov 26 03:08:25 nfs daemon.err /etc/init.d/nfs[228]: ERROR: cannot start nfs as rpc.statd would not start
我已经为 LXC 创建了一个自定义 apparmor 配置文件(发现这里)给服务足够的运行权限,但这并没有帮助。
答案1
事实证明我需要CAP_SETPCAP
运行 NFS 服务器的能力。
这可以通过编辑容器的配置文件/etc/pve/lxc/CTID.conf
(其中CTID
是您的容器 ID)来完成,如下所示:
....
# clear cap.drop
lxc.cap.drop:
# copy drop list from /usr/share/lxc/config/common.conf
lxc.cap.drop = mac_admin mac_override sys_time sys_module sys_rawio
# copy drop list from /usr/share/lxc/config/alpine.common.conf with setpcap commented
lxc.cap.drop = audit_write
lxc.cap.drop = ipc_owner
lxc.cap.drop = mknod
# lxc.cap.drop = setpcap
lxc.cap.drop = sys_nice
lxc.cap.drop = sys_pacct
lxc.cap.drop = sys_ptrace
lxc.cap.drop = sys_rawio
lxc.cap.drop = sys_resource
lxc.cap.drop = sys_tty_config
lxc.cap.drop = syslog
lxc.cap.drop = wake_alarm
瞧!
