在CentOS 7 上部署NFS服务器

yum install nfs-utils

systemctl start rpcbind
systemctl start nfs-server
systemctl start nfs-lock
systemctl start nfs-idmap

systemctl enable rpcbind
systemctl enable nfs-server
systemctl enable nfs-lock
systemctl enable nfs-idmap

vim /etc/exports
#添加以下配置
/share    192.168.0.3(rw,sync,no_root_squash,no_subtree_check)  192.168.0.4(rw,sync,no_root_squash,no_subtree_check)  192.168.0.5(rw,sync,no_root_squash,no_subtree_check)

# /share – 共享目录
# /192.168.0.3 – 允许访问NFS的客户端IP地址段
# /rw – 允许对共享目录进行读写
# /sync – 实时同步共享目录
# /no_root_squash – 允许root访问
# /no_all_squash - 允许用户授权
# /no_subtree_check - 如果卷的一部分被输出，从客户端发出请求文件的一个常规的调用子目录检查验证卷的相应部分。如果是整个卷输出，禁止这个检查可以加速传输。

vim /etc/sysconfig/nfs
#添加
MOUNTD_PORT=892
RQUOTAD_PORT=875
STATD_PORT=662
STATD_OUTGOING_PORT=2020

vim /etc/modprobe.d/lockd.conf

#添加
options lockd nlm_tcpport=32803
options lockd nlm_udpport=32769
