无法在Centos 7中启动NFS :未能发出方法调用:没有这样的文件或目录
提问于 2015-06-23 21:27:53
我无法在CentOS7中启动NFS服务器。
下载的软件包：
yum -y install nfs-utils
yum -y install nfs-utils-lib启用/启动服务
systemctl enable/start rpcbind
systemctl enable/start nfs-server
systemctl enable/start nfs-lock
systemctl enable/start nfs-idmap这导致：
systemctl enable nfs-lock
Failed to issue method call: No such file or directory
systemctl enable nfs-idmap
Failed to issue method call: No such file or directory创建了该份额：
mkdir -p /test
chmod 777 /test出口罚款：
exportfs
/test clientip/24但是，在执行systemctl重新启动nfs-server时，如果出现依赖关系错误，则会失败，journalctl显示：
[user@server /]# journalctl -xn | grep failed
-- Subject: Unit proc-fs-nfsd.mount has failed
-- Unit proc-fs-nfsd.mount has failed.
-- The result is failed.

-- Subject: Unit nfs-mountd.service has failed
-- Unit nfs-mountd.service has failed.
Jun 23 17:06:41 open而systemctl列表单元状态也显示失败。

我用@user136564 's的帖子解决了这个问题。
这解决了我的问题https://www.centos.org/forums/viewtopic.php?f=47&t=53896
我发现我的问题是，即使我在systemd中启用了rpcbind，并且可以手动启动它，它也不会在引导时启动。
这些命令是我在CentOS Linux发行版7.2.1511 (核心)
上所做的。
安装nfs-utils
yum install -y nfs-utils将文本附加到/etc/fstab
192.168.1.100:/mnt/nfs-server /mnt/nfs-client nfs defaults,nofail,x-systemd.automount 0 0有些文章说noauto,x-systemd.automount更好，但对我来说，没有noauto就行了。
检查挂载是否工作
systemctl start rpcbind
systemctl enable rpcbind
mount -a解决了问题CentOS 7不会在引导
上自动挂载
将文本追加到/usr/lib/systemd/system/nfs-idmap.service的末尾
[Install]
WantedBy=multi-user.target将文本追加到/usr/lib/systemd/system/nfs-lock.service的末尾
[Install]
WantedBy=nfs.target启用相关服务
systemctl enable nfs-idmapd.service
systemctl enable rpc-statd.service
systemctl enable rpcbind.socket
systemctl status nfs-idmapd.service -l
systemctl status rpc-statd.service –l然后
重新启动操作系统，我得到了.
