NFS服务搭建使用

需求：由于线上业务有一些数据存在了Redis数据库和mysql数据库中了，导致了数据较大迁移起来比较麻烦，所以准备搭建NFS来做WEB的共享磁盘，存储这些数据。

服务端搭建：

yum 安装，启动 (有错误，是因为rpcbind服务没启动)

先启动rpcbind服务

[root@vm-10-112-38-104 ]# /etc/init.d/rpcbind restart

启动NFS服务

[root@vm-10-112-38-104 ~]# service nfs start

更改配置文件：共享/nfs目录，rw读写权限，sync时时同步，no_root_squash root用户有所有权限，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。

[root@vm-10-112-38-104 ~]# vi /etc/exports 

/nfs *(rw,sync,no_root_squash,no_subtree_check)

客户端测试：　　

挂载到本地目录：

[root@vm-10-129-93-51 ~]# mkdir /nfs

[root@vm-10-129-93-51 ~]#

[root@vm-10-129-93-51 ~]#

[root@vm-10-129-93-51 ~]#

[root@vm-10-129-93-51 ~]#

[root@vm-10-129-93-51 ~]#

[root@vm-10-129-93-51 ~]# mount -t nfs 10.112.38.104:/nfs /nfs 
[root@vm-10-129-93-51 ~]#

写入/etc/fstab ，开机自动加载

echo "10.112.x.x:/nfs  /nfs nfs defaults 0 0" >> /etc/fstab
