(Linux系统之使用autofs自动挂载nfs共享)
一、autofs介绍
二、检查本地系统环境
1.检查系统版本
[root@jeven ~]# cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"
CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"
2.检查系统内核版本
[root@jeven ~]# uname -r
6.1.8-1.el7.elrepo.x86_64
三、部署nfs服务
1.检查系统nfs软件包
[root@jeven ~]# yum list installed |grep nfs
libnfsidmap.x86_64 0.25-19.el7 @anaconda
nfs-utils.x86_64 1:1.3.0-0.61.el7 @anaconda
nfs4-acl-tools.x86_64 0.3.3-19.el7 @anaconda
2.安装nfs
[root@jeven ~]# yum install nfs-utils rpcbind -y
Loaded plugins: fastestmirror, langpacks

3.创建共享目录
mkdir -p /nfs #创建共享目录
4.编辑配置文件
echo "/nfs *(insecure,rw,sync,no_root_squash)" > /etc/exports
5.重启nfs相关服务
systemctl enable --now rpcbind
systemctl enable --now nfs-server
6.查看nfs服务状态
[root@jeven ~]# systemctl status nfs-server
● nfs-server.service - NFS server and services

四、远程客户端测试nfs共享
[root@server001 ~]# showmount -e 192.168.3.166
Export list for 192.168.3.166:
/nfs *
五、配置autofs自动挂载
1.安装autofs软件包
[root@server001 ~]# yum -y install autofs
Loaded plugins: fastestmirror, product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.

2.设置服务开机自启
[root@server001 ~]# systemctl enable --now autofs
Created symlink from /etc/systemd/system/multi-user.target.wants/autofs.service to /usr/lib/systemd/system/autofs.service.
3.配置autofs自动挂载
[root@server001 ~]# grep home /etc/auto.master
/home /etc/auto.nfs
[root@server001 ~]# cat /etc/auto.nfs
zhangsan -fstype=nfs,rw 192.168.3.166:/nfs
4.重启autofs服务
[root@server001 ~]# systemctl restart autofs
[root@server001 ~]#
六、测试客户端autofs自动挂载
1.进入/home/zhangsan目录
[root@server001 ~]# cd /home/zhangsan
[root@server001 zhangsan]# df -h |grep zhangsan
192.168.3.166:/nfs 106G 49G 58G 47% /home/zhangsan
2.测试共享目录创建文件
- 客户端写入文件
[root@server001 zhangsan]# touch aa.txt
[root@server001 zhangsan]# ls
aa.txt
- nfs服务端查看文件
[root@jeven ~]# cd /nfs/
[root@jeven nfs]# ls
aa.txt
