* 起因

程序哥要登录一台机器看所有javalog 但是有些机器跑的程序日志名是一样的于是只能是多个 nfs server 一个client 然后登录client机器就可以查看6台机的log

client 172.31.27.83 server 172.31.25.239,java03 ,04,05,06 加上01自己一共6台机器

* server install

** java2

yum -y install nfs-utils rpcbind
firewall-cmd --add-service=nfs --permanent --zone=public


systemctl enable nfs-server
systemctl start  nfs-server
# nfs client ip 
echo "/data/logs/hello/ 172.31.27.83(rw,sync,no_root_squash)" >> /etc/exports

systemctl  restart  rpcbind

exportfs -arv

#其它几台机器是一样的 在此就不写上了

client

* client inst

yum -y install nfs-utils

apt-get install nfs-common#debina

config

4java02

mkdir  -p /data/logs/java02/hello/
mount 172.31.25.239:/data/logs/hello/  /data/logs/java02/hello/

记得加入 fstab
172.31.27.83:/data/logs/hello/  /home/logs/java01/hello nfs defaults 0 0
172.31.25.239:/data/logs/hello/  /home/logs/java02/hello nfs defaults 0 0
172.31.16.171:/data/logs/hello/  /home/logs/java03/hello nfs defaults 0 0

4java03

mkdir  -p /data/logs/java02/hello/
mount 172.31.16.171:/data/logs/hello/  /data/logs/java02/hello/

其它一致，在此不写

mount 172.31.16.171:/data/logs/hello/  /data/logs/java03/hello/

mount.nfs: access denied by server while mounting 172.31.16.171:/data/logs/hello/

troubleshooting

on nfs server

# 不然会 showmount -e 没东西  
mount  172.31.26.183:/data/logs/hello/  /data/logs/java04/hello/
mount.nfs: access denied by server while mounting 172.31.26.183:/data/logs/hello/
