1 Deciding whether to root

Root_user () {
[$UID-ne 0] && {echo "Please use root user"; exit 1;}
}

2 Determine if you can connect to the Internet

Con_internet () {
PING-C2 mirrors.aliyun.com &>/dev/null
[$?-ne 0] && {echo "Cannot connect to the Internet"; exit 1;}
}

3 is selinux off

Selinux_cls () {
if [! getenforce = "Disabled"];then
Setenforce 0
Sed-ir ' s/^ (selinux=). */\1disabled/'/etc/sysconfig/selinux
Fi
}

4 Iptables whether to close

Iptables_cls () {
if! /etc/init.d/iptables status|grep-q ' not running ';
/etc/init.d/iptables stop
Chkconfig iptables off
Fi
}

5 Yum Modifications

Yum_mod () {
if! Grep-q Aliyun/etc/yum.repos.d/centos-base.repo;then
\cp/etc/yum.repos.d/centos-base.repo/etc/yum.repos.d/centos-base.reop.bak

}

6 Install NFS Server

Ins_nfs () {
If [ rpm -aq rpcbind nfs-utils|wc -l -lt 2];then
Yum install-y rpcbind nfs-utils &>/dev/null
If [$?-ne 0];then
echo "NFS Server Install fail"
Exit 1
Fi
/etc/init.d/rpcbind Start &>/dev/null
/etc/init.d/nfs Start &>/dev/null
Fi
If [ netstat -lntup|egrep "rpcbind|nfs"|wc -l -lt 6];then
Action "NFS Server install ..."/bin/fasle
Else
Action "NFS Server install ..."/bin/true
Fi
}

7 Configuring the/etc/exports document, the NFS server default directory is set to/nfsnobody

Nfs_conf () {
[-d/nfsnobody] | | Mkdir/nfsnobody
Chown-r Nfsnobody:nfsnobody/nfsnobody
if [-s/etc/exports];then
Echo '/nfsnobody 192.168.0.0/24 (rw,all_squash,sync) ' >>/etc/exports
Else
Echo '/nfsnobody 192.168.0.0/24 (rw,all_squash,sync) ' >/etc/exports
Fi
Exportfs-r &>/dev/null
}

8 Optimizing NFS, setting/etc/sysctl.conf documentation

Sysctl_opt () {
default=$ (sysctl-a|grep "[Rw]mem_default" |awk ' {print $NF} ')
max=$ (sysctl-a|grep "[Rw]mem_max" |awk ' {print $NF} ')
If ["$default"! = "8388608 8388608"-a "$max"! = "16777216 16777216"];then
Cat >>/etc/sysctl.conf<<eof
Net.core.rmem_default = 8388608
Net.core.wmem_default = 8388608
Net.core.rmem_max = 16777216
Net.core.wmem_max = 16777216
Eof
Sysctl-p &>/dev/null
Fi
}

9 Place NFS Server on boot to/etc/rc.local

Nfs_boot_start () {
If [ egrep "(rpcbind|nfs) start" /etc/rc.local|wc -l -lt 2];then
ECHO-E "\n#nfs server 20171129\n/etc/init.d/rpcbind start\n/etc/init.d/nfs start" >>/etc/rc.local
Fi
}
