一、CentOS设置

1. 更换阿里源

  1. curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
  3. yum makecache

2. 安装网络工具

yum install net-tools wget -y

3. 使用阿里NTP服务

yum install chrony -y

sed -i "/server/d" /etc/chrony.conf

vi /etc/chrony.conf 增加 server ntp.aliyun.com iburst

systemctl restart chronyd

chronyc tracking

4. 设置主机名

hostnamectl set-hostname nfs

5. 关闭防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service

二、安装NFS

1. 安装类库

yum install -y nfs-utils

2. 设置配置

vi /etc/exports

/home/nfs_root/ *(insecure,rw,sync,no_root_squash)

3. 启动NFS服务

mkdir /home/nfs_root

systemctl enable rpcbind
systemctl enable nfs-server

systemctl start rpcbind
systemctl start nfs-server

exportfs -r

4. 检查是否生效

exportfs

以上指令应该输出/home/nfs_root /home/nfs_root

三、客户端测试NFS

1. 安装软件包

yum install -y nfs-utils

2. 检查NFS服务

showmount -e 192.168.1.229

执行以上命令如果成功则输出

Export list for 192.168.1.229:
/root/nfs_root *

3. 挂载NFS

mkdir /root/nfsmount

mount -t nfs 192.168.1.229:/home/nfs_root /root/nfsmount

echo "hello nfs server" > /root/nfsmount/test.txt

4. NFS服务器执行

cat /root/nfs_root/test.txt
