    简单利用rsync实现文件的同步

    实验环境

    192.168.13.234 rsync服务端

    192.168.13.226 rsync客户端

    服务端的配置

    yum -y install rsync
    # rpm -qa|grep rsync
    rsync-3.0.9-17.el7.x86_64
    uname -r
    #3.10.0-514.el7.x86_64
    systemctl stop firewalld
    rsync --version
    # rsync version 3.0.9 protocol version 30
    mkdir /test  
    chown -R rsync.rsync /data/test

    编辑vim /etc/rsyncd.conf文件

    vim /etc/rsyncd.conf
    uid = root
    gid = root
    use chroot = yes
    max connections = 10
    pid file = /var/run/rsyncd.pid
    # exclude = lost+found/
    # transfer logging = yes
    lock file = /var/run/rsync.lock
    log file = /var/log/rsyncd.log
    timeout = 300
    # ignore nonreadable = yes
    # dont compress   = *.gz *.tgz *.zip *.z *.Z *.rpm *.deb *.bz2

    # [ftp]
    #       path = /home/ftp
    #       comment = ftp export area
    [test]
    path = /test
    ignore errors
    read only = false
    list = false
    hosts allow = *
    hosts deny = 0.0.0.0/32
    auth users = rsync_backup
    secrets file = /etc/rsync.password

     

    #编辑密码
    echo 'rsync_backup:123456' >/etc/rsync.password
    chmod 600 /etc/rsync.password
    systemctl restart rsyncd
    ss -lntup|grep rsync
    #tcp   LISTEN     0     5         *:873                   *:*                   users:(("rsync",pid=10210,fd=4))
    #tcp   LISTEN     0     5     [::]:873               [::]:*                   users:(("rsync",pid=10210,fd=5))
    cd /test/
    touch file{1..4}

    客户端

    echo '123456' >/etc/rsync.password
    chmod 600 etc/rsync.password
    systemctl stop firewalld
    yum -y install rsync

    rsync --version

    测试

    在客户端上测试

    向服务端同步文件

    将客户端/tmp下的文件通步在服务端的/test下

    rsync  -Rav /tmp  rsync_backup@192.168.13.234::test   --password-file=/etc/rsync.password

    服务端向客户端同步文件

    将服务端的/test下的文件通步在客户端/tmp下

    rsync -Rav  rsync_backup@192.168.13.234::test   /tmp --password-file=/etc/rsync.password

    rsync+inotify的实时文件自动同步

    1 配置rsync服务

    实验环境

    192.168.13.234 rsync的服务器

    192.168.13.226 inotify的服务器

    实现将192.168.13.226 服务器的/backup 目录下的文件实时的同步到192.168.13.234 的test模块下即 /test目录下

    1 在rsync的服务器 配置rsync

    具体操作见上面的操作

    2 在inotify的服务器 配置inotify

    yum -y install gcc*
    cd /usr/local/
    wget http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz
    tar zxf inotify-tools-3.14.tar.gz
    cd inotify-tools-3.14
    ./configure --prefix=/usr/local/inotify-3.14
    make && make install
    cd /usr/local/inotify-3.14/

    创建监控脚本inotify.sh

    [root@laso inotify-3.14]# cat inotify.sh 
    #!/bin/bash
    #para
    host01=192.168.13.234  #rsync服务器地址
    src=/backup        #本地监控的目录
    dst=test         #rsync服务器的模块名称
    user=rsync_backup    #rsync服务器的虚拟用户
    rsync_passfile=/usr/local/inotify-3.14/rsync.password  #本地调用rsync服务的密码文件
    inotify_home=/usr/local/inotify-3.14    #inotify的安装目录
    #judge
    if [ ! -e "$src" ]
    || [ ! -e "${rsync_passfile}" ]
    || [ ! -e "${inotify_home}/bin/inotifywait" ]
    || [ ! -e "/usr/bin/rsync" ];
    then
    echo "Check File and Folder"
    exit 9
    fi
    ${inotify_home}/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f' -e close_write,delete,create,attrib $src
    | while read file
    do
    # rsync -avzP --delete --timeout=100 --password-file=${rsync_passfile} $src $user@$host01::$dst >/dev/null 2>&1
    cd $src && rsync -aruz -R --delete ./  --timeout=100 $user@$host01::$dst --password-file=${rsync_passfile} >/dev/null 2>&1
    # --delete 保持文件的一致性
    done
    exit 0

    创建/backup 目录

    mkdir /backup 

    创建认证密码的文件

    [root@laso inotify-3.14]# pwd
    /usr/local/inotify-3.14
    [root@laso inotify-3.14]# cat rsync.password
    123456

    脚本创建完毕,丢给后台运行。(开机启动的话放到rc.local文档即可)

    sh inotify.sh &

    检查服务

    [root@laso inotify-3.14]#  ps -ef |grep inotify
    root     22786 20066  0 11:57 pts/0    00:00:00 sh inotify.sh
    root     22787 22786  0 11:57 pts/0    00:00:00 /usr/local/inotify-3.14/bin/inotifywait -mrq --timefmt %d/%m/%y %H:%M --format %T %w%f -e close_write,delete,create,attrib /backup
    root     22788 22786  0 11:57 pts/0    00:00:00 sh inotify.sh
    root     22790 20066  0 11:57 pts/0    00:00:00 grep --color=auto inotify

    测试

    在192.168.13.226 inotify的服务器 /backup目录创建测试文件

    [root@laso backup]# touch  inotify{1..14}
    [root@laso backup]# ls
    inotify1   inotify11 inotify13 inotify2 inotify4 inotify6 inotify8
    inotify10 inotify12 inotify14 inotify3 inotify5 inotify7 inotify9

    在192.168.13.234 rsync的服务器/test目录下检测同步的文件

    [root@laso test]# ls
    inotify1   inotify11 inotify13 inotify2 inotify4 inotify6 inotify8
    inotify10 inotify12 inotify14 inotify3 inotify5 inotify7 inotify9
    [root@laso test]# pwd
    /test

    测试成功,完成了同步文件
