rsync同步配置

rsync配置

环境说明：

masterrsync_server:192.168.124.101

slaversync_client: 192.168.124.102

同步需求：

将client中的/var/test的文件同步至master;

将master中的/var/ab的文件同步至slave;

一、master，slave均安装rsync服务：

#yum –y install rsync

二、master端配置：

2.1添加rsyncd.conf：

vim /etc/rsyncd.conf ############################################# #/etc/rsyncd.conf motd file = /rsyncd.motd transfer logging = yes port = 873 address = 192.168.124.101 uid = root gid = root use chroot = no max connections = 200 timeout = 300 log file = /var/log/rsyncd.log pid file = /var/run/rsyncd.pid lock file = /var/run/rsyc.lock [test] path = /var/test/ ignore errors read only = false list = false #exclude = phpmyadmin/ #hosts allow = 192.168.1.0/255.255.255.0 hosts allow =192.168.124.102 hosts deny = * auth users = rsync_backup secrets file = /etc/rsync.password [ab] path = /var/ab/ ignore errors read only = false list = false #exclude = phpmyadmin/ #hosts allow = 192.168.1.0/255.255.255.0 hosts allow =192.168.124.102 hosts deny = * auth users = rsync_backup secrets file = /etc/rsync.password

 

2.2修改同步目录权限：

mkdir /var/test /var/ab chown -R root.root /var/test chown -R root.root /var/ab

 

2.3添加同步账号并授权：

echo "rsync_backup:bbc0123!" >/etc/rsync.password cat /etc/rsync.password chmod 600 /etc/rsync.password

2.4 rsync后台启动，并加入开机启动：

/usr/bin/rsync --daemon ps -ef | grep rsync | grep -v grep netstat -aplnt | grep 873   echo “/usr/bin/rsync --daemon” >>/etc/rc.local pkill rsync

三、slave端配置：

3.1修改目录同步权限：

mkdir /var/test /var/ab chown -R root.root /var/test chown -R root.root /var/ab

3.2添加同步账号并授权：

echo "bbc0123!" >/etc/rsync.password chmod 600 /etc/rsync.password

3.3添加同步脚本及定时任务并将定时任务：

vi /var/tb.sh #!/bin/bash sleep 2s host=192.168.124.101 #rsync_server地址 src1=/var/test/ dst1=test src2=/var/ab/ dst2=ab user=rsync_backup Passfile=/etc/rsync.password function rsync(){          echo `date +"%F  %T %:z"` 'rsync start begining' >> /var/monitor_tb.log #从客户端同步至服务端          /usr/bin/rsync -avz  --delete --progress --password-file=$Passfile $src1 $user@$host::$dst1  >/dev/null 2>&1 #从服务端同步至客户端          /usr/bin/rsync -avz  --delete --progress --password-file=$Passfile $user@$host::$src2 $src2  >/dev/null 2>&1          echo `date +"%F  %T %:z"` 'rsync start end' >> /var/monitor_tb.log                } function checkRsync(){              num=`ps -ef|grep  '/usr/bin/rsync -avz --delete --progress --password-file'|grep -v grep|awk  '{print $8}' |uniq |wc -l`          #echo $num >>  /var/monitor_tb.log          if [[ $num -eq 0 ]];  then                    echo `date  +"%F %T %:z"` "文件同步开始">>  /var/monitor_tb.log                    rsync          else                    echo `date  +"%F %T %:z"` '文件同步正在进行，稍后开始同步'  >> /var/monitor_tb.log                    exit 0;                    fi } checkRsync

编辑定时任务

crontab -l */1 * * * * /bin/bash /var/tb.sh

 

PS：1、同步测试

#将client中的/var/test的文件同步至master;(均在clien执行) #/usr/bin/rsync -avz --delete --progress  --password-file=/etc/rsync.password /var/test/ rsync_backup@192.168.124.101::test   #将master中的/var/ab的文件同步至slave;（均在clien执行） #/usr/bin/rsync -avz --delete --progress  --password-file=/etc/rsync.password rsync_backup@192.168.124.101::ab /var/ab/
