linux服务器端启动NFS报“Job for nfs-server.service canceled.”的解决办法

linux服务器端启动NFS报“Job for nfs-server.service canceled.”的解决办法

网上百度了好久都没找到这个报错的原因（白嫖失败）

1. 打开linux的系统日志：

tail -f /var/log/messages

2. 再次重启NFS服务：

systemcrl restart nfs

果不其然再次报错：

Job for nfs-server.service canceled.

3. 去日志里看看有啥有用的消息：

Nov  3 16:48:31 localhost exportfs[9503]: exportfs: No host name given with /share (rw), suggest *(rw) to avoid warning
Nov  3 16:48:31 localhost exportfs[9503]: exportfs: /etc/exports [2]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/share".

好家伙，原来是export配置文件出了问题

4. 去修改相关的配置文件，正确格式之一如下：

/ 10.3.0.0/16(rw,sync,insecure,no_subtree_check,no_root_squash)
#服务器端共项目录  -权限   -network   客户端ip
/share -rw -network 10.3.45.37
~                                                                                                   
~                                                                                                   
~                                                                                                   
~                                  

大功告成，重启成功!
