搭建rsync服务器,实现文件备份同步

一、服务器端rsync的安装和配置

1. 服务器上的rsync安装

   在此已本地虚拟机192.168.1.113为服务器做例子，客户端192.168.1.114作为备份同步的客户端。
   

   直接yum安装：

   yum install rsync

2. rsync的配置

rsync的主要有以下三个配置文件rsyncd.conf(主配置文件)、rsyncd.secrets(密码文件)、rsyncd.motd(rysnc服务器信息)

服务器配置文件，该文件默认不存在，请创建它.现在我在/etc目录下创建rsync.d目录，再创建

rsyncd.conf、rsyncd.secrets、rsyncd.motd

　　具体步骤如下：

[root@yearnfar local ] # cd /etc/ [root@yearnfar etc] # mkdir rsync.d [root@yearnfar etc] # cd rsync.d/ [root@yearnfar rsync .d] # touch rsyncd.conf [root@yearnfar rsync .d] # touch rsyncd.secrets [root@yearnfar rsync .d] # touch rsyncd.motd [root@yearnfar rsync .d] # chmod 600 rsyncd.secrets ##将rsyncd.secrets这个密码文件的文件属性设为root拥有, 且权限要设为600 [root@yearnfar rsync .d] # ll 总用量 0 -rw-r--r--. 1 root root 0 9月 21 12:14 rsyncd.conf -rw-r--r--. 1 root root 0 9月 21 12:14 rsyncd.motd -rw-------. 1 root root 0 9月 21 12:14 rsyncd.secrets

以下是rsyncd.conf的配置

# Distributed under the terms of the GNU General Public License v2 # 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 # pid file = /var/run/rsyncd.pid port = 873 address = 115.28.34.xxx #修改为自己的ip uid = root gid = root use chroot = yes read only = yes #limit access to private LANs hosts allow=* hosts deny=* max connections = 5 motd file = /etc/rsync .d /rsyncd .motd #This will give you a separate log file #log file = /var/log/rsync.log #This will log every file transferred - up to 85,000+ per user, per sync #transfer logging = yes log format = %t %a %m %f %b syslog facility = local3 timeout = 300 [mysql_backup] path = /data/mysql_backup list= yes ignore errors auth users = yearnfar secrets file = /etc/rsync .d /rsyncd .secrets comment = backup mysql exclude = git/

以下是rsyncd.secrets的配置

tjj:123456

ps:tjj是登陆用户，后面是密码

以下是rsyncd.motd的配置

3.编写启动脚本





[root@yearnfar rsync .d] # vi /etc/init.d/rsync #!/bin/bash # # rsyncd This shell script takes care of starting and stopping # standalone rsync. # # chkconfig: - 99 50 # description: rsync is a file transport daemon # processname: rsync # config: /etc/rsync.d/rsyncd.conf # Source function library . /etc/rc .d /init .d /functions RETVAL=0 rsync = "/usr/local/bin/rsync" prog= "rsync" CFILE= "/etc/rsync.d/rsyncd.conf" start() { # Start daemons. [ -x $ rsync ] || \ { echo "FATAL: No such programme" ; exit 4; } [ -f $CFILE ] || \ { echo "FATAL: config file does not exist" ; exit 6; } echo -n $ "Starting $prog: " daemon $ rsync --daemon --config=$CFILE RETVAL=$? [ $RETVAL - eq 0 ] && touch /var/lock/subsys/ $prog echo return $RETVAL } stop() { # Stop daemons. echo -n $ "Stopping $prog: " killproc $prog -QUIT RETVAL=$? echo [ $RETVAL - eq 0 ] && rm -f /var/lock/subsys/ $prog return $RETVAL } # call the function we defined case "$1" in start) start ;; stop) stop ;; restart|reload) stop start RETVAL=$? ;; status) status $prog RETVAL=$? ;; *) echo $ "Usage: $0 {start|stop|restart|reload|status}" exit 2 esac exit $RETVAL [root@yearnfar rsync .d] # chmod +x /etc/init.d/rsync [root@yearnfar rsync .d] # /etc/init.d/rsync start 正在启动 rsync ： [确定] [root@yearnfar rsync .d] # chkconfig --add /etc/init.d/rsync ## 添加到开机启动 [root@yearnfar rsync .d] # chkconfig --level 235 rsync on ## 添加到开机启动

4.测试链接

[root@yearnfar rsync .d] # rsync --list-only [email protected]::mysql_backup ++++++++++++++++++++++++++++++++++++++++++++++ Welcome to use the mike.org.cn rsync services! centos6.3 yearnfar ++++++++++++++++++++++++++++++++++++++++++++++ Password: drwxr-xr-x 4096 2015 /09/20 15:24:06 . drwxr-xr-x 4096 2015 /09/21 04:00:01 201509

二、在客户机（192.168.1.114）上同步服务器

1. 也要装上rsync,直接yum install rsync即可

2. 编写密码文件

   vi /home/psw/rsync.secrets

   chmod 600 /home/psw/rsync.secrets(必须赋予600权限)

3. 编写链接备份的脚本sh

   vi /home/shell/rsync.sh

   

  chmod+x /home/shell/rsync.sh

     ./home/shell/rsync.sh

ps:sync -avzP --delete --password-file=密码文件  tjj@119.146.203.245::mysql_backup 备份目录

 4.同步成功
