一、rsync部署
-
服务器：source 192.168.58.130 （进行数据备份的主机）
-
客户端：targetpc 192.168.58.131 （备份存储的主机）
push推数据
1、编写rsync配置文件
#192.168.58.131 # 在客户端上编写rsync配置文件，创建一个存放备份的同步目录 [root@targetpc ~]# vim /etc/rsyncd.conf # /etc/rsyncd: configuration file for rsync daemon mode # See rsyncd.conf man page for more options. # configuration example: # uid = nobody # gid = nobody # use chroot = yes # max connections = 4 # pid file = /var/run/rsyncd.pid # exclude = lost+found/ # transfer logging = yes # timeout = 900 # ignore nonreadable = yes # dont compress = *.gz *.tgz *.zip *.z *.Z *.rpm *.deb *.bz2 # [ftp] # path = /home/ftp # comment = ftp export area #在这些内容后面加上下面的内容
#加上 port=873 address = 192.168.58.131 uid = root gid = root use chroot = yes max connections = 4 pid file = /var/run/rsyncd.pid lock file = /var/run/rsync.lock log file = /var/log/rsyncd.log motd file = /etc/rsyncd.motd hosts allow = 192.168.58.0/24 [data] path = /data/backup comment = bakcup data read only = false list = yes auth users = rsyncuser secrets file = /etc/rsync.passwd
#192.168.58.131 # 创建密码文件，格式 用户名:密码 # 设置密码文件权限为600或者700 [root@targetpc ~]# touch /etc/rsync.passwd [root@targetpc ~]# vim /etc/rsync.passwd rsyncuser:123456 [root@targetpc ~]# chmod 600 /etc/rsync.passwd
#192.168.58.131 # 创建欢迎信息文件 [root@targetpc ~]# echo "Welcome to Backup Server" > /etc/rsyncd.motd [root@targetpc ~]# systemctl start rsyncd [root@targetpc ~]# mkdir -p /data/backup [root@targetpc ~]# cd /data/backup
2、备份测试
#192.168.58.130 [root@source ~]# mkdir /data [root@source ~]# cd /data [root@source data]# touch 1.txt [root@source data]# mkdir aaa [root@source data]# rsync -avz /data/* rsyncuser@192.168.58.131::data Welcome to Backup Server Password: sending incremental file list 1.txt aaa/ sent 124 bytes received 43 bytes 9.03 bytes/sec total size is 0 speedup is 0.00 [root@source data]# touch 2.txt [root@source data]# ls 1.txt 2.txt aaa [root@source data]# rsync -avz /data/* rsyncuser@192.168.58.131::data Welcome to Backup Server Password: sending incremental file list 2.txt sent 137 bytes received 36 bytes 9.89 bytes/sec total size is 0 speedup is 0.00
3、检验结果
#192.168.58.131 [root@targetpc backup]# ls 1.txt 2.txt aaa [root@targetpc backup]# touch 3.txt [root@targetpc backup]# ls 1.txt 2.txt 3.txt aaa
#192.168.58.130 [root@source data]# rsync -avz --delete /data/ rsyncuser@192.168.58.131::data Welcome to Backup Server Password: sending incremental file list deleting 3.txt sent 125 bytes received 22 bytes 8.91 bytes/sec total size is 0 speedup is 0.00
#192.168.58.131 [root@targetpc backup]# ls 1.txt 2.txt aaa
非交互式：
如果想不输入密码，可以使用--password-file参数指定密码
#192.168.58.130 [root@source data]# vim /etc/rsync.passwd 123456 [root@source data]# chmod 600 /etc/rsync.passwd [root@source data]# rsync -avz --delete /data/ rsyncuser@192.168.58.131::data --password-file=/etc/rsync.passwd Welcome to Backup Server sending incremental file list deleting data/aaa/ deleting data/2.txt deleting data/1.txt deleting data/ ./ sent 132 bytes received 70 bytes 13.93 bytes/sec total size is 0 speedup is 0.00
#192.168.58.131 [root@targetpc backup]# ls 1.txt 2.txt aaa
二、rsync+sersync 实现数据实时同步
1、安装sersync服务
#192.168.58.130 [root@source data]# cd [root@source ~]# rz rz waiting to receive.**[root@source ~]# ls anaconda-ks.cfg ceph-release-1-1.el7.noarch.rpm init.sh sersync2.5.4_64bit_binary_stable_final.tar.gz shell [root@source ~]# ls anaconda-ks.cfg ceph-release-1-1.el7.noarch.rpm init.sh sersync2.5.4_64bit_binary_stable_final.tar.gz shell [root@source ~]# tar xf sersync2.5.4_64bit_binary_stable_final.tar.gz [root@source ~]# ls anaconda-ks.cfg GNU-Linux-x86 sersync2.5.4_64bit_binary_stable_final.tar.gz ceph-release-1-1.el7.noarch.rpm init.sh shell [root@source ~]# cd GNU-Linux-x86/ [root@source GNU-Linux-x86]# ls confxml.xml sersync2 [root@source GNU-Linux-x86]# vim confxml.xml <inotify><delete start="true"/><createFolder start="true"/><createFile start="false"/><closeWrite start="true"/><moveFrom start="true"/><moveTo start="true"/><attrib start="false"/><modify start="false"/></inotify><sersync><localpath watch="/opt/tongbu"><remote ip="127.0.0.1" name="tongbu1"/><!--<remote ip="192.168.8.39" name="tongbu"/>--><!--<remote ip="192.168.8.40" name="tongbu"/>--></localpath><rsync><commonParams params="-artuz"/><auth start="false" users="root" passwordfile="/etc/rsync.pas"/><userDefinedPort start="false" port="874"/><!-- port=874 --><timeout start="false" time="100"/><!-- timeout=100 --><ssh start="false"/></rsync>

#192.168.58.130 # 开启sersync守护进程同步数据，即实时同步。 # -r参数，先做一次完全同步，再做差异同步。 [root@source GNU-Linux-x86]# ./sersync2 -d -r -o ./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： ./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 rsyncuser passwordfile is /etc/rsync.passwd 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 ./ rsyncuser@192.168.58.131::data --password-file=/etc/rsync.passwd >/dev/null 2>&1 #或者 [root@source GNU-Linux-x86]# nohup ./sersync2 -r -o ./confxml.xml & [1] 117240
2、检验结果
#192.168.58.130 #更改名称，查看变化 [root@source data]# mv aaa AAA root@source data]# ls 1.txt 2.txt AAA
#192.168.58.131 #检测到名称已变 [root@targetpc backup]# ls 1.txt 2.txt AAA
pull拉取数据
以上的同步过程都是服务端主动推送数据给目标主机（服务器），这里演示下目标主机主动拉取数据进行同步。
1、编写rsync配置文件
#192.168.58.130 [root@source ~]# vim /etc/rsyncd.conf #在这个文件里加入下面内容# ort=873 address = 192.168.58.130 uid = root gid = root use chroot = yes max connections = 4 pid file = /var/run/rsyncd.pid lock file = /var/run/rsync.lock log file = /var/log/rsyncd.log motd file = /etc/rsyncd.motd hosts allow = 192.168.58.0/24 [data] path = /data comment = master data read only = false list = yes auth users = rsyncuser secrets file = /etc/rsync.passwd
# 认证文件 [root@source ~]# vim /etc/rsync.passwd rsyncuser:123456 # 服务端上启动rsync [root@source ~]# systemctl start rsyncd [root@source ~]# netstat -antup | grep 873 tcp 0 0 192.168.58.130:873 0.0.0.0:* LISTEN 15646/rsync # 看到以上结果，说明服务端的rsync服务已经配置完成。 # 开放873端口号，允许通过873端口号拉取数据 [root@source ~]# cd /data [root@source data]# mkdir BBB [root@source data]# ls 1.txt 2.txt AAA BBB
2、检验结果
#192.168.58.131 # 目标主机上拉取数据 [root@targetpc backup]# rsync -avz rsyncuser@192.168.58.130::data /data/backup/ Password: receiving incremental file list ./ BBB/ sent 32 bytes received 145 bytes 9.57 bytes/sec total size is 0 speedup is 0.00 [root@targetpc backup]# ls 1.txt 2.txt AAA BBB
三、脚本编写
计划将服务器的/data目录的文件实时发送到客户端/data/backup目录中，操作前请检查服务器是否有该目录
1、客户端脚本编写
#!/bin/bash
#客户端配置
#编写rsync配置文件
read -p "请输入符合此掩码的当前主机IP(默认掩码为255.255.255.0)：" ip
ip1=$(echo $ip | awk -F. '{print $1"."$2"."$3}')
echo "
port=873
address = $ip
uid = root
gid = root
use chroot = yes
max connections = 4
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
motd file = /etc/rsyncd.motd
hosts allow = $ip1.0/24
[data]
path = /data/backup
comment = bakcup data
read only = false
list = yes
auth users = rsyncuser
secrets file = /etc/rsync.passwd
" > /etc/rsyncd.conf
touch /etc/rsync.passwd
echo "rsyncuser:123456" > /etc/rsync.passwd
chmod 600 /etc/rsync.passwd
echo "Welcome to Backup Server" > /etc/rsyncd.motd
systemctl restart rsyncd
mkdir -p /data/backup
2、服务器脚本编写
#!/bin/bash #服务端配置 read -p "请输入符合此掩码的客户端主机IP(默认掩码为255.255.255.0)：" ip echo "123456" > /etc/rsync.passwd chmod 600 /etc/rsync.passwd rsync -avz --delete /data/ rsyncuser@$ip::data --password-file=/etc/rsync.passwd
