Centos 7 中无法启动 NFS：无法发出方法调用：没有这样的文件或目录

Centos 7 中无法启动 NFS：无法发出方法调用：没有这样的文件或目录

我无法在 CentOS7 中启动 NFS 服务器。

下载的包：

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

创建共享：

mkdir -p /test
chmod 777 /test

出口罚款：

exportfs
/test           clientip/24

但是，在执行systemctlrestart时nfs-server，它失败并出现依赖错误，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

并且systemctl列表单位状态也显示失败

systemctl list-units | grep nfs
proc-fs-nfsd.mount                      loaded failed failed    NFSD configuration filesystem

nfs-idmapd.service                      loaded failed failed    NFSv4 ID-name mapping service

客户反映，按照上面的错误，我认为是正常的：

RPC: Remote system errorRPC: Port mapper failure - RPC: Timed out.

我通过 @user136564 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 rpcbind 不会在启动时启动，即使我在 systemd 中启用了它并且我可以手动启动它。

这些命令是我在 CentOS Linux 版本 7.2.1511（核心）上执行的操作

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noauto对我来说没有效果。

检查挂载是否有效

systemctl start rpcbind
systemctl enable rpcbind
mount -a

修复 CentOS 7 启动时无法自动挂载 NFS 的问题

将文本附加到 /usr/lib/systemd/system/nfs-idmap.service 的末尾 
[Install]
WantedBy=multi-user.target
将文本附加到 /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，我明白了。

shutdown -r now
