linux网络目录挂载方法

NFS:
1,首先要配置服务端
编辑/etc/exports,加入:
/opt/data0/courseware 172.17.1.0/24(rw,sync,no_root_squash) #IP是客户端的地址, 目录是要共享出的目录

2,然后启动nfs服务:
/etc/init.d/nfs start
systemctl start nfs
systemctl start rpcbind
修改/etc/exprots文件后需要重新启动才能生效
/etc/init.d/nfs restart

3,SSH到客户端上就可以挂载了
mount -t nfs 192.168.3.16:/data/bakup /home/data

4，修改服务器的目录权限后就可以在客户断对服务器目录文件进行编辑了
chmod -R 777 /opt/data0/courseware

防火墙时可以正常使用NFS服务：
a] TCP/UDP 111 – RPC 4.0 portmapper
b] TCP/UDP 2049 – NFSD (nfs server)
c] Portmap 静态端口—在/etc/sysconfig/nfs文件中定义的一系列TCP/UDP端口

vim /etc/sysconfig/nfs
RQUOTAD_PORT=16005
LOCKD_TCPPORT=16004
LOCKD_UDPPORT=16004
MOUNTD_PORT=16002
STATD_PORT=16003
STATD_OUTGOING_PORT=16006

service nfs restart
