NFS AutoFS
两台机器
一、NFS服务端配置
1.配置本地 hosts 解析
[root@nfs-server ~]# echo "192.168.195.145 "nfs-server" >> /etc/hosts [root@nfs-server ~]# echo "192.168.195.146 "client" >> /etc/hosts [root@nfs-server ~]# tail -n2 /etc/hosts 192.168.195.145 nfs-server 192.168.195.146 client
2.安装 nfs 以及 rpc 所需要的包
[root@nfs-server ~]# yum -y install nfs-utils rpcbind
3.启动 rpc 和 nfs 服务并设置为开机自启动
[root@nfs-server ~]# systemctl start rpcbind //先启动 rpc 服务再启动 nfs 服务。 [root@nfs-server ~]# systemctl start nfs [root@nfs-server ~]# systemctl enable rpcbind [root@nfs-server ~]# systemctl enable nfs
4.配置挂载目录
[root@nfs-server ~]# vi /etc/exports /mnt 192.168.195.0/24(rw,async) /opt *(rw,async)
5.关闭防火墙和selinux
[root@nfs-server ~]# systemctl stop firewalld [root@nfs-server ~]# systemctl disable firewalld [root@nfs-server ~]# setenforce 0 [root@nfs-server ~]# vi /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of three values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted
6.验证NFS
[root@nfs-server ~]# systemctl restart rpcbind nfs-server [root@nfs-server ~]# showmount -e 127.0.0.1 Export list for 192.168.195.145: /opt * /mnt 192.168.195.0/24
二、NFS客户端挂载
1.安装NFS
[root@nfs-client ~]# yum -y install rpcbind nfs-utils
2.配置本地 hosts 解析
[root@nfs-client users]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.195.145 nfs-server 192.168.195.146 nfs-client
3.验证NFS
[root@nfs-client ~]# showmount -e 192.168.195.145 Export list for 192.168.195.145: /opt * /mnt 192.168.195.0/24
4.挂载NFS
[root@nfs-client ~]# mount -t nfs 192.168.195.145:/mnt /mnt [root@nfs-client ~]# mount -t nfs 192.168.195.145:/opt /opt [root@nfs-client ~]# df -Th 文件系统 类型 容量 已用 可用 已用% 挂载点 192.168.195.145:/mnt nfs4 17G 1.5G 16G 9% /mnt 192.168.195.145:/opt nfs4 17G 1.5G 16G 9% /opt
三、使用autofs配置自动挂载
1.配置本地 hosts 解析
[root@client users]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.195.145 nfs-server 192.168.195.147 client
2.创建挂载目录并挂载
[root@client ~]# mkdir /nfsdir [root@client ~]# mount -t nfs 192.168.195.145:/mnt /nfsdir [root@client ~]# df -Th 文件系统 类型 容量 已用 可用 已用% 挂载点 192.168.195.145:/mnt nfs4 17G 1.5G 16G 9% /mnt 192.168.195.145:/opt nfs4 17G 1.5G 16G 9% /opt 192.168.195.145:/mnt nfs4 17G 1.5G 16G 9% /nfsdir
3.编辑 “/etc/auto.master” 主配置文件
[root@client ~]# echo "/nfsdir /etc/auto.user" >> /etc/auto.master
4.编辑 “/etc/auto.user” 子配置文件
[root@client ~]# echo "users -fstype=nfs,rw,sync,no_root_squash nfs-server:/home" >> /etc/auto.user
5.启动 autofs 服务并设置为开机自启动
#服务端 [root@server ~]# mkdir /mnt/users #客户端 [root@client ~]# cd /nfsdir/ [root@client nfsdir]# ls -lh 总用量 0 [root@client nfsdir]# cd users [root@client users]# pwd /nfsdir/users [root@client users]# ls -lh /nfsdir/ total 0 drwxr-xr-x 2 root root 6 Mar 16 03:26 users
6.测试autofs自动挂载
#服务端 [root@server ~]# mkdir /mnt/users #客户端 [root@client ~]# cd /nfsdir/ [root@client nfsdir]# ls -lh 总用量 0 [root@client nfsdir]# cd users [root@client users]# pwd /nfsdir/users [root@client users]# ls -lh /nfsdir/ total 0 drwxr-xr-x 2 root root 6 Mar 16 03:26 users
