10.3.3
NFS服务器端操作系统及水源版本

1 [[email protected] ~]# cat /etc/RedHat-release 
2 CentOS release 6.7 (Final)
3 [[email protected] ~]# username -r
4 [[email protected] ~]# uname -r
5 2.6.32-573.el6.x86_64
6 [[email protected] ~]# uname -m
7 x86_64

10.4
NFS服务安装前准备

10.4.1
查询nfs-utils和rpcbind包是不是安装

1 [[email protected] ~]# rpm -qa nfs-utils rpcbind   ##查询结果为两个安装包都未安装
2 [[email protected] ~]#

文化扩充:

设置NFS软件设置的3种艺术:

检查:rpm
-qa nfs-utils rpcbind ←最佳

1)方法1:yum
-y install nfs-utils rpcbind

2)方法2:通过系统光盘里的rpm包安装,命令如:rpm
-ivh nfs-utils-1.2.3-36.e16.x86_64.rpm

3)方法3:LANG=en

yum
grouplist|grep -i nfs

yum
groupinstall “NFS file server” -y

 

10.4.2运用格局1设置所需软件包

图片 2

10.4.3检查安装包是不是安装上

1 [[email protected] ~]# rpm -qa nfs-utils rpcbind
2 rpcbind-0.2.0-11.el6_7.x86_64
3 nfs-utils-1.2.3-64.el6.x86_64

10.4.4
接下去运维相应的服务

 1 [[email protected] ~]# /etc/init.d/rpcbind status  <==检查rpcbind服务状态
 2 rpcbind is stopped
 3 [[email protected] ~]# rpcinfo -p localhost  <==rpcbind服务未启动检查 rpcinfo信息报错
 4 rpcinfo: can't contact portmapper: RPC: Remote system error - Connection refused
 5 [[email protected] ~]# /etc/init.d/rpcbind start  <==启动rpcbind服务
 6 Starting rpcbind:                                          [  OK  ]
 7 [[email protected] ~]# /etc/init.d/rpcbind status
 8 rpcbind (pid  2083) is running...
 9 ​[[email protected] ~]# /etc/init.d/nfs status  <==查看nfs服务状态
10 rpc.svcgssd is stopped
11 rpc.mountd is stopped
12 nfsd is stopped
13 rpc.rquotad is stopped
14 [[email protected] ~]# /etc/init.d/nfs start  <==启动nfs服务
15 Starting NFS services:                                     [  OK  ]
16 Starting NFS quotas:                                       [  OK  ]
17 Starting NFS mountd:                                       [  OK  ]
18 Starting NFS daemon:                                       [  OK  ]
19 Starting RPC idmapd:                                       [  OK  ]

10.4.5
设置开机自运维

1 [[email protected] ~]# chkconfig --level 35  nfs on  <==设置nfs服务开机自启动
2 [[email protected] ~]# chkconfig --list nfs
3 nfs             0:off   1:off   2:off   3:on    4:off   5:on    6:off
4 [[email protected] ~]# chkconfig --level 35 rpcbind on
5 [[email protected] ~]# chkconfig --list rpcbind     <==<==设置rpcbind服务开机自启动
6 rpcbind         0:off   1:off   2:on    3:on    4:on    5:on    6:off

10.5 配置NFS服务端

10.5.1
NFS服务端配置文件路线

NFS服务配置文件路线为:/etc/exports,并且暗中同意是为空。

1 [[email protected] ~]# ll /etc/exports
2 -rw-r--r--. 1 root root 0 Jan 12  2010 /etc/exports
3 [[email protected] ~]# cat /etc/exports
4 [[email protected] ~]# 

10.5.2
编辑NFS服务端配置文件

1 [[email protected] ~]# vim /etc/exports
2 /data 192.168.1.0/24(rw,sync,all_squash)  <==添加如下内容

1 [[email protected] ~]# vim /etc/exports
2 /data 192.168.1.0/24(rw,sync,all_squash)  <==添加如下内容
3 ​[[email protected] ~]# mkdir -p /data  <==创建共享目录/data
4 [[email protected] ~]# ls -ld /data
5 drwxr-xr-x. 3 root root 4096 Nov 26 15:19 /data  <==当前共享目录的属主属组分别为root
6 [[email protected] ~]# chown -R nfsnobody.nfsnobody /data  <==修改/data及子文件属主属组为nfsnobody
7 [[email protected] ~]# ls -ld /data                      
8 drwxr-xr-x. 3 nfsnobody nfsnobody 4096 Nov 26 15:19 /data

10.5.3
重新加载NFS服务(优雅重启)

1 [[email protected] ~]# /etc/init.d/nfs reload ===exportfs -r
2 [[email protected] ~]# cat /var/lib/nfs/etab                
3 /data   192.168.1.0/24(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534,sec=sys,rw,root_squash,all_squash)
4 [[email protected] ~]# showmount -e 192.168.1.14 <==挂载前首先检查有权限需要挂载的信息
5 Export list for 192.168.1.14:
6 /data 192.168.1.0/24 <---可以看到共享/data目录

10.5.4
检查或测验挂载

1 [[email protected]er test]# mount -t nfs 192.168.1.14:/data /mnt  ##将/data共享目录挂载到/mnt目录
2 [[email protected] test]# df -h
3 Filesystem          Size  Used Avail Use% Mounted on
4 /dev/sda3           7.1G  1.5G  5.3G  22% /
5 tmpfs               279M     0  279M   0% /dev/shm
6 /dev/sda1           190M   36M  145M  20% /boot
7 192.168.1.14:/data  7.1G  1.5G  5.3G  22% /mnt

​注意:

巨型公司办事景况统一根据运转标准将劳动的运维写到/etc/rc.local文件里,而不用chkconfig管理。把/etc/rc.local文件作为本机的严重性档案,全数服务的开机自运转都必需放入/etc/rc.local。那样标准的好处是,一旦有运转职员离职,或许职业迁移时都因此/etc/rc.local很轻便查看服务器相关的劳动,能够平价运行管理。而且把运维命令放入到/etc/rc.local文件中显著要足够运转服务的讲解。

 1 [[email protected] test]# vim /etc/rc.local 
 2 #!/bin/sh

 4 # This script will be executed *after* all the other init scripts.

 8 touch /var/lock/subsys/local
 9 #start up nfs services by zhurui at 20160226
10 /etc/init.d/rpcbind start <==开机自启rpcbind服务
11 /etc/init.d/nfs start  <==开机自启nfs服务

mount挂载质量优化参数选项

(1)禁止更新目录及文件时间戳挂载

1 mount -t nfs -o noatime,nodiratime 192.168.1.14:/data

(2)安全加优化的挂载格局

1 mount -t nfs -o nosuid,noexec,nodev,noatime,nodiratime,intr,rsize=131072,wsize=131072 192.168.1.14:/data /mnt

(3)暗中认可的挂载格局

1 mount -t nfs 192.168.1.14:/data /mnt

10.7
NFS内核优化

对应的现实性内核优化命令:

1 cat >>/etc/sysctl.conf<<EOF
2 net.core.wmem_default = 8388608
3 net.core.rmem_default = 8388608
4 net.core.rmem_max = 16777216
5 net.core.wmem_max = 16777216
6 EOF

执行sysctl -p生效
