各服务器环境
1、创建gjs用户和组
[root@host ~]# groupadd -g 666 gjs
[root@host ~]# useradd -u 666 -g 666 gjs
2、关闭防火墙和selinux
[root@nfs ~]# systemctl stop firewalld
[root@nfs ~]# systemctl disable firewalld
[root@nfs ~]# getenforce 查看是否开启
[root@nfs ~]# setenforce 0
[root@nfs ~]# vim /etc/selinux/config
SELINUX=disabled

3># 创建备份的目录和密码文件
[root@backup ~]# mkdir /web_upload
[root@backup ~]# chown -R gjs.gjs /web_upload/
[root@backup ~]# echo 'gjs_backup:123456' > /etc/rsyncd.passwd
[root@backup ~]# cat /etc/rsyncd.passwd

[root@backup ~]# chmod 600 /etc/rsyncd.passwd
4># 启动rsyncd并检查
[root@backup ~]# systemctl start rsyncd
[root@backup ~]# netstat -lntup | grep rsync
[root@backup ~]# ps aux | grep rsync

NFS服务端
1>#安装NFS和rpcbind
[root@nfs ~]# yum install -y nfs-utils rpcbind
#如果是centos6需要单独安装rpcbind，centos7可以不单独安装
2>#创建数据目录 用于挂载到web服务器
[root@nfs ~]# mkdir /web_upload
[root@nfs ~]# chown -R gjs.gjs /web_upload
3>#配置/etc/exports
[root@nfs ~]# vim /etc/exports

4>#启动NFS服务
[root@nfs ~]# systemctl start rpcbind nfs-server
#如果是centos6，启动时必须先启动rpcbind，centos7会自动启动
#验证启动
[root@nfs ~]# ps -ef | grep nfs
5>#验证NFS配置
[root@nfs ~]# cat /var/lib/nfs/etab

rsyncd客户端
# 安装rsyncd，rsync守护进程
[root@backup ~]# yum install -y rsyncd
# 创建密码文件
[root@backup ~]# echo '123456' > /etc/rsync.passwd
[root@backup ~]# cat /etc/rsync.passwd
123456
# 将密码文件的权限改成600
[root@backup ~]# chmod 600 /etc/rsync.passwd
# 启动rsync
[root@backup ~]# systemctl start rsyncd
# 检查启动情况
[root@backup ~]# netstat -lntup | grep rsync

root 1149 0.0 0.1 114748 1124 ? Ss 02:54 0:00 /usr/bin/rsync --daemon --no-detach
NFS服务端
1>#安装NFS和rpcbind
[root@nfs ~]# yum install -y nfs-utils rpcbind
#如果是centos6需要单独安装rpcbind，centos7可以不单独安装
2>#配置/etc/exports
NFS服务程序的配置文件为/etc/exports，需要严格按照共享目录的路径 允许访问的NFS客户端（共享权限参数）格式书写，定义要共享的目录与相应的权限，具体书写方式如下图所示。
[root@nfs ~]# vim /etc/exports
/data 172.16.1.0/24(rw,sync,all_squash)
| 语法 | /data | 172.16.1.0/24 | (rw,sync,all_squash) |
| -------- | ---------- | -------------------- | ------------------------- |
| 语法含义 | 共享的目录 | 允许连接的客户端网段 | 允许的操作（参数1,参数2） |
3>#创建数据目录 用于挂载到web服务器
[root@nfs ~]# mkdir /data
[root@nfs ~]# chown -R gjs.gjs /data
4>#启动NFS服务
[root@nfs ~]# systemctl start rpcbind nfs-server
#如果是centos6，启动时必须先启动rpcbind，centos7会自动启动
#验证启动
[root@nfs ~]# ps -ef | grep nfs
5>#验证NFS配置
[root@nfs ~]# cat /var/lib/nfs/etab
/data 172.16.1.0/24(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,all_squash,no_subtree_check,secure_locks,acl,no_pnfs,anonuid=65534,anongid=65534,sec=sys,rw,secure,root_squash,all_squash)

User gjs
Group gjs
3># 修改权限
[root@web01 ~]# chown -R gjs.gjs /var/www/html/

[root@web01 ~]# df -h
172.16.1.31:/web_upload 16G 1.7G 15G 11% /var/www/html/upload
6、上传测试
# 浏览器10.0.0.7上传文件
# 查看nfs与web端的文件
[root@web01 ~]# ll /var/www/html/upload
[root@nfs ~]# ll /web_upload/
7、rsyncd服务端配置
1># 安装rsyncd，rsync的守护进程
[root@backup ~]# yum install -y rsyncd

8、NFS推送文件测试
# 确保rsyncd服务正常运行
[root@nfs /web_upload]# rsync -axz ./ gjs_backup@172.16.1.41::upload --password-file=/etc/rsync.passwd
9、sersync服务端配置
