用户态的NFS Server

2022-07-06 1 分钟阅读

NFS Server 很常用，但是坑也是巨大的。之前在京东运维 Hadoop 集群的时候碰到过脑裂，原因就是 NFS 引起的。

关键 NFS 是内核态的，一旦崩溃，那么客户端的所有命令，ls、df、du等等，统统无反应，结果是很悲剧的。

下面要推荐一下 nfs-ganesha ，它是用户态的nfs-server，支持v3和v4，而nfs缺省是内核态的v3。

强烈推荐大家用这个，而不是用内核态的，并且 nfs-ganesha 还是支持 glusterFS 的。

yum install -y centos-release-nfs-ganesha30.noarch
    
vi /etc/ganesha/ganesha.conf
%include /etc/ganesha/exports/gv0.conf
    
vi /etc/ganesha/exports/gv0.conf
EXPORT{
    Export_Id = 1 ;   # Export ID unique to each export
    Path = "/mnt/upload";
    Pseudo = /upload;
    FSAL {
        name = VFS;
    }
    Access_type = RW;    # Access permissions
    Squash = No_root_squash; # To enable/disable root squashing
    Disable_ACL = TRUE;  # To enable/disable ACL
    Protocols = "4" ;    # NFS protocols supported
    Transports = "UDP","TCP" ; # Transport protocols supported
    SecType = "sys";     # Security flavors supported
}

#启动
systemctl restart nfs-ganesha

#手动mount的方法
mount -t nfs -o soft,intr,rsize=8192,wsize=8192,timeo=900,proto=tcp,vers=4 192.168.31.2:/upload /mnt/nfs-upload
    
#自动mount的方法
cat /etc/fstab
192.168.31.2:/upload /mnt/nfs-upload nfs rw,vers=4,addr=192.168.31.2,clientaddr=192.168.31.8 0 0

注意id对齐问题可能要用到rpcidmapd
