1臺nfs主被服務器都下載nfs、keepalived

yum install nfs-utils rpcbind keepalived -y

2臺nfs服務器nfs掛載目錄及配置必須相同

3.在主nfs服務期編寫一個死循環並後臺運行

while true

do

if [ `/etc/init.d/nfs status|awk ‘NR==2{print $NF}‘` = "stopped" ]

then

/etc/init.d/keepalived stop

fi

done

4.再掛載服務器寫一個守護進程並執行守護進程

掛載服務器腳本內容：

while true

do

if [ `showmount -e 172.16.1.31|wc -l` -eq 0 ]

then

umount /application/nginx-1.10.3/html/blog/wp-content/uploads

umount /application/nginx-1.10.3/html/bbs/data/attachment/image

umount /application/nginx-1.10.3/html/www/uploads/allimg

mount -t nfs 172.16.1.30:/data/blog /application/nginx-1.10.3/html/blog/wp-content/uploads

mount -t nfs 172.16.1.30:/data/bbs /application/nginx-1.10.3/html/bbs/data/attachment/image

mount -t nfs 172.16.1.30:/data/www /application/nginx-1.10.3/html/www/uploads/allimg

exit

fi

done

nfs+keepalived高可用
