rsync异机备份案例.docx

第一步：实验环境两台机器：backup和web在backup机器上，检查是否安装rsync，[root@backup ~]# rpm -qa | grep rsync独立运行 rsync 服务最简单的独立运行 rsync 服务的方法是执行如下的命令：# /usr/bin/rsync --daemon您可以将上面的命令写入 /etc/rc.local 文件以便在每次启动服务器时运行 rsync 服务。当然，您也可以写一个脚本在开机时自动启动 rysnc 服务。配置文件 rsyncd.conf 默认在 /etc 目录下。为了将所有与 rsync 服务相关的文件放在单独的目录下，可以执行如下命令：# mkdir /etc/rsyncd# touch /etc/rsyncd/rsyncd.conf# ln -s /etc/rsyncd/rsyncd.conf /etc/rsyncd.conf[root@backup backup]# cat /etc/rsyncd/rsyncd.conf # Minimal configuration file for rsync daemon# See rsync(1) and rsyncd.conf(5) man pages for help# This line is required by the /etc/init.d/rsyncd script# GLOBAL OPTIONSuid = rsync gid = rsync use chroot = no #limit access to private LANshosts allow=/ / /hosts deny=* max connections = 5 pid file = /var/run/rsyncd.pid auth users = rsync_backupsecrets file = /etc/rsync.password#lock file = /var/run/rsync.lock motd file = /etc/rsyncd/rsyncd.motd #This will give you a separate log filelog file = /var/log/rsync.log #This will log every file transferred - up to 85,000+ per user, per synctransfer logging = yes log format = %t %a %m %f %bsyslog facility = local3timeout = 300[back]path=/backup/read only=no创建密码文件 /etc/rsync.passwordecho rsync_backup:oldboy /etc/rsync.password修改权限：chmod 600 /etc/rsync.password修改文件夹所有者：首先保证rysnc用户存在，若不存在 则建立rsync用户useradd rsyncchown rsync.rsync /backup/先关闭防火墙：service iptables stop873端口 打开启动 rsyncrsync --daemon --config=/etc/rsyncd.conf?在web机器上操作：# mkdir /etc/rsyncd# touch /etc/rsyncd/rsyncd.conf# ln -s /etc/rsyncd/rsyncd.conf /etc/rsyncd.conf在web服务器上进行操作，安装过程同上，配置文件如下：echo oldboy /etc/rsync.passwordchmod 600 /etc/rsync.password[root@web ~]# cat /etc/rsyncd/rsyncd.conf # Minimal configuration file for rsync daemon# See rsync(1) and rsyncd.conf(5) man pages for help# This line is required by the /etc/init.d/rsyncd script# GLOBAL OPTIO
