• Rsync保持两服务器数据一致


    服务端配置
    1,发现原系统已安装rsync,就直接利用
    #rpm -qa | grep rsync
    rsync-2.5.7-5.3E
    #ls /etc/xinetd.d/rsync
    /etc/xinetd.d/rsync
    

    2,主要是更改rsyncd.conf和 rsync这两个文件

    #mkdir /etc/rsyncd
    #cd /etc/rsyncd
    #ls
    

    rsyncd.conf    #主配置文件

    rsyncd.motd    #banner消息

    rsyncd.secrets #里面的内容用户名:密码

    3,#cat rsyncd.conf
    pid file = /var/run/rsyncd.pid
    port = 873
    address = 服务器IP
    uid = root
    gid = root
    use chroot = yes
    read only = yes
    max connections = 5
    motd file = /etc/rsyncd/rsyncd.motd
    log file = /var/log/rsync.log
    [home]
    path = /home
    list = yes
    ignore errors
    auth users = root
    hosts allow = 客户端IP
    secrets file = /etc/rsyncd/rsyncd.secrets
    strict modes =  yes
    [home2]
    path = /home2
    list = yes
    ignore errors
    auth users = root
    hosts allow = 客户端IP
    secrets file = /etc/rsyncd/rsyncd.secrets
    strict modes =  yes
    [home3]
    path = /home3
    list = yes
    ignore errors
    auth users = root
    hosts allow = 客户端IP
    secrets file = /etc/rsyncd/rsyncd.secrets
    strict modes =  yes
    [cvs]
    path = /cvs
    list = yes
    ignore errors
    auth users = root
    hosts allow = 客户端IP
    secrets file = /etc/rsyncd/rsyncd.secrets
    strict modes =  yes
    #
    

    4,#cat /etc/xinetd.d/rsync

    # default: off
    # description: The rsync server is a good addition to an ftp server, as it 
    #       allows crc checksumming etc.
    service rsync
    {
            disable = no    #开
            socket_type     = stream
            wait            = no
            user            = root
            server          = /usr/bin/rsync
            server_args     = --daemon --config=/etc/rsyncd/rsyncd.conf  #主配置文件的位置
            log_on_failure  += USERID
    }
    # service xinetd restart
    Stopping xinetd: [  OK  ]
    Starting xinetd: [  OK  ]
    # netstat -tulpn | grep :873
    tcp        0      0 0.0.0.0:873                 0.0.0.0:*                   LISTEN      26323/xinetd   
    
        
    客户端配置
    1,
    # rpm -qa | grep rsync
    rsync-3.0.6-4.el5_7.1
    

    2,#直接用命令复制

    rsync  -avz --progress --delete  root@服务端IP::home /home --password-file=/etc/rsyncd.secrets
    rsync  -avz --progress --delete  root@服务端IP::home2 /home2 --password-file=/etc/rsyncd.secrets
    rsync  -avz --progress --delete  root@服务端IP::home3 /home3 --password-file=/etc/rsyncd.secrets
    rsync  -avz --progress --delete  root@服务端IP::cvs /cvs --password-file=/etc/rsyncd.secrets
    

    客户端的rsyncd.secrets文件里只要写上密码即可

    其中-a 代表rlptgoD,其实就是保证目录及文件的权限,修改时间,属主,组等一致
        --progress 查看进程
        --delete   客户端内容和服务的一致,当服务端有删除时,客户端也要删除
    另外由于strict modes 开了,rsyncd.secrets文件权限要设置成600
