第六章 NFS、rsync等统一用户相关操作

一、统一用户

1.httpd
2.NFS挂载目录
3.rsync

1.所有服务器统一创建用户

[root@web01 ~]# groupadd www -g 666
[root@web01 ~]# useradd www -u 666 -g 666

2.修改httpd用户

[root@web01 ~]# vim /etc/httpd/conf/httpd.conf
User www
Group www

#重启服务
[root@web01 ~]# systemctl restart httpd
[root@web01 ~]# ps -ef | grep httpd
root      31537      1  1 21:57 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
www       31538  31537  0 21:57 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
www       31539  31537  0 21:57 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
www       31540  31537  0 21:57 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
www       31541  31537  0 21:57 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
www       31542  31537  0 21:57 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
root      31544  18601  0 21:57 pts/1    00:00:00 grep --color=auto httpd

3.修改NFS服务端权限

[root@NFS /data]# vim /etc/exports
/data 172.16.1.0/24(rw,sync,all_squash,anonuid=666,anongid=666)

#重启
[root@NFS /data]# systemctl restart NFS

4.修改rsync用户

[root@backup ~]#vim /etc/rsyncd.conf
uid = www
gid = www
port = 873
fake super = yes
use chroot = no
max connections = 200
timeout = 600
ignore errors
read only = false
list = false
auth users = rsync_backup
secrets file = /etc/rsync.passwd
log file = /var/log/rsyncd.log
#####################################
[backup]
comment = welcome to oldboyedu backup!
path = /backup

5.NFS服务端重新授权目录

[root@NFS ~]# chown -R www.www /data/

6.web端重新挂载

[root@web01 /var/www/html]# umount /var/www/html/upload
[root@web01 /var/www/html]# mount -t NFS 172.16.1.31:/data ./upload

7.rsync服务端重新授权目录

[root@backup ~]#chown -R www:www /backup

二、NFS总结

1.NFS储存优点
1)简单易用,部署方便
2)数据可查,服务稳定

2.NFS的服务缺点
1)存在单点故障, 如果构建高可用维护麻烦web->NFS()->backup
2)NFS数据明文, 并不对数据做任何校验。
3)客户端挂载NFS服务没有密码验证, 安全性一般(内网使用)

3.NFS应用建议
1)开机挂载
如果希望NFS文件共享服务能一直有效,则需要将其写入到fstab文件中
#编辑fstab文件
[root@NFS-client ~]# vim /etc/fstab
172.16.1.31:/data /NFSdir NFS defaults 0 0
#验证fstab是否写正确
[root@NFS-client ~]# mount -a

2)生产场景应将静态数据尽可能往前端推,减少后端存储压力
3)必须将存储里的静态资源通过CDN缓存,jpgpngmp4avicssjs
4)如果没有缓存或架构本身历史遗留问题太大, 在多存储也无用

三、rsync+NFS解决单点故障

1.环境准备

主机

角色IP
backup rsync服务端,NFS服务端 172.16.1.41
NFS rsync客户端,NFS服务端 172.16.1.31
web01 rsync客户端,NFS客户端 172.16.1.7,10.0.0.7

secrets file = /etc/rsync.passwd
log file = /var/log/rsyncd.log
#####################################
[backup]
comment = "文件备份目录"
path = /backup

[data]
comment = "数据备份目录"
path = /data

3.重启rsync
[root@backup ~]# systemctl restart rsyncd

6.NFS数据实时备份到backup服务器

1.安装inotify
[root@nfs ~]# yum -y install inotify-tools

2.编写脚本实时备份data目录
[root@nfs /data]# vim /scripts/backup_data.sh
#!/bin/bash
dir=/data
export RSYNC_PASSWORD=123456
/usr/bin/inotifywait  -mrq  --format '%w %f' -e create,delete,attrib,close_write  $dir | while read line;do

[root@web01 ~]# umount -lf /var/www/html/upload
[root@web01 ~]# mount -t nfs 172.16.1.41:/data /var/www/html/upload

四、实时同步

1.实时同步简单介绍

1.概述
实时同步是一种只要当前目录发生变化则会触发一个事件,事件触发后会将变化的目录同步至远程服务器

2.为什么要实时同步
保证数据的连续性, 减少人力维护成本,解决nfs单点故障

3.实时同步数据选择
sersync+RSYNC(√)、inotify+rsync
Inotify是一个通知接口,用来监控文件系统的各种变化,如果文件存取,删除,移动。可以非常方便地实现文件异动告警,增量备份,并针对目录或文件的变化及时作出响应。rsync+inotify可以实触发式实时同步增量备份

sersync是国人基于rsync+inotify-tools开发的工具,不仅保留了优点同时还强化了实时监控,文件过滤,简化配置等功能,帮助用户提高运行效率,节省时间和网络资源。

2.安装sersync(NFS服务器)

1.安装sersync和inotify
[root@nfs01 ~]# yum install rsync inotify-tools -y

2.下载serdync软件包
[root@nfs01 ~]# wget https://raw.githubusercontent.com/wsgzao/sersync/master/sersync2.5.4_64bit_binary_stable_final.tar.gz

3.解压安装包
[root@nfs ~]# tar xf sersync2.5.4_64bit_binary_stable_final.tar.gz

4.移动并改名
[root@nfs ~]# mv GNU-Linux-x86 /usr/local/sersync

5.修改配置文件
[root@nfs ~]# cat /usr/local/sersync/confxml.xml

execute:echo 327679 > /proc/sys/fs/inotify/max_queued_events
parse the command param
_______________________________________________________
参数-d:启用守护进程模式
参数-r:在监控前,将监控目录与远程主机用rsync命令推送一遍
c参数-n: 指定开启守护线程的数量,默认为10个

参数-m:单独启用其他模块,使用 -m refreshCDN 开启刷新CDN模块
参数-m:单独启用其他模块,使用 -m socket 开启socket模块
参数-m:单独启用其他模块,使用 -m http 开启http模块
不加-m参数,则默认执行同步程序

[root@nfs ~]# /usr/local/sersync/sersync2 -dro /usr/local/sersync/confxml.xml
set the system param
execute:echo 50000000 > /proc/sys/fs/inotify/max_user_watches
execute:echo 327679 > /proc/sys/fs/inotify/max_queued_events
parse the command param
option: -d run as a daemon
option: -r rsync all the local files to the remote servers before the sersync work
option: -o config xml name: /usr/local/sersync/confxml.xml
daemon thread num: 10
parse xml config file
host ip : localhost host port: 8008
will ignore the inotify createFile event
daemon start,sersync run behind the console
use rsync password-file :
user is rsync_backup
passwordfile is /etc/rsync.password
config xml parse success
please set /etc/rsyncd.conf max connections=0 Manually
sersync working thread 12  = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads)
Max threads numbers is: 22 = 12(Thread pool nums) + 10(Sub threads)
please according your cpu ,use -n param to adjust the cpu rate
------------------------------------------
rsync the directory recursivly to the remote servers once
working please wait...
execute command: cd /data && rsync -artuz -R --delete ./ rsync_backup@172.16.1.41::data --password-file=/etc/rsync.password >/dev/null 2>&1
run the sersync:
watch path is: /data

6.创建密码文件并设置权限
[root@nfs ~]# echo "123456" >/etc/rsync.password
[root@nfs ~]# chmod 600 /etc/rsync.password

7.启动数据实时同步
[root@nfs ~]# /usr/local/sersync/sersync2 -dro /usr/local/sersync/confxml.xml
set the system param
execute:echo 50000000 > /proc/sys/fs/inotify/max_user_watches
execute:echo 327679 > /proc/sys/fs/inotify/max_queued_events
parse the command param
option: -d run as a daemon
option: -r rsync all the local files to the remote servers before the sersync work
option: -o config xml name: /usr/local/sersync/confxml.xml
daemon thread num: 10
parse xml config file
host ip : localhost host port: 8008
will ignore the inotify createFile event
daemon start,sersync run behind the console
use rsync password-file :
user is rsync_backup
passwordfile is /etc/rsync.password
config xml parse success
please set /etc/rsyncd.conf max connections=0 Manually
sersync working thread 12  = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads)
Max threads numbers is: 22 = 12(Thread pool nums) + 10(Sub threads)
please according your cpu ,use -n param to adjust the cpu rate
------------------------------------------
rsync the directory recursivly to the remote servers once
working please wait...
execute command: cd /web/data && rsync -artuz -R --delete ./ rsync_backup@172.16.1.41::data --password-file=/etc/rsync.password >/dev/null 2>&1
run the sersync:
watch path is: /web/data

8.backup搭建NFS服务端

1.安装nfs和rpcbind
[root@backup ~]# yum -y install nfs rpcbind

2.配置nfs服务
[root@backup ~]# vim /etc/exports
/backup 172.16.1.0/24(rw,sync,all_squash,anonuid=666,anongid=666)

3.重启服务并验证
[root@backup ~]# cat /var/lib/nfs/etab
/backup 172.16.1.0/24(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,all_squash,no_subtree_check,secure_locks,acl,no_pnfs,anonuid=666,anongid=666,sec=sys,rw,secure,root_squash,all_squash)

9.测试

1.访问交作业页面,上传图片

2.查看web服务器
[[root@web01 /var/www/html/upload]# ll
total 48
-rw-r--r-- 1 www www 46257 Aug 14 21:05 1_jh.jpg

3.查看nfs服务器data目录
[root@nfs /web/data]# ll
total 48
-rw-r--r-- 1 www www 46257 Aug 14 21:05 1_jh.jpg

4.查看backup服务器data目录
[root@backup /data]# ll
total 48
-rw-r--r-- 1 www www 46257 Aug 14 21:05 1_jh.jpg
