fstab掛載nfs

### 配置fstab
cat /etc/fstab 
myhuaweicloud.com:/share/standard/ /webser/www/FineReport/WEB-INF/reportlets/standard nfs vers=4,minorversion=0,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,_netdev,noresvport 0 0
myhuaweicloud.com:/share/tenant/   /webser/www/FineReport/WEB-INF/reportlets/tenant nfs   vers=4,minorversion=0,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,_netdev,noresvport 0 0

### 掛載時報錯
[root@report-prod reportlets]# mount -a
mount.nfs: Protocol not supported

### 查看mountvers
cat /etc/nfsmount.conf
# Server Mountd Version
# mountvers=3

### 修改/etc/fstab，兩邊要保持一致
vers=4 -> vers=3
