Lsyncd For CentOS配置步骤

CentOS 6 配置lsyncd实现应用目录自动同步备份

 

官方Reference:  https://axkibe.github.io/lsyncd

#首先关掉SElinux

#临时关闭:setenforce 0

#永久关闭: vim /etc/selinux/config 设置为disabled

#lsync需要调用rsync，故需要在客户端和服务端分别安装rsync软件包

 

1.

#rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

注:如果遇到URL地址无法解析的情况,需检查配置的DNS Server地址

cat >>/etc/resolv.conf <<EOF
    nameserver 114.114.114.114
    nameserver 8.8.8.8
EOF

　　

2.

#yum –y install lsyncd

　　

3.修改/etc/lsyncd.conf配置文件,内容如下:

-- User configuration file for lsyncd.
-- Simple example for default rsync, but executing moves through on the target.
-- For more examples, see /usr/share/doc/lsyncd*/examples/
--sync{default.rsyncssh,source="/var/www/html", host="localhost", targetdir="/tmp/htmlcopy/"}

settings {
    logfile ="/var/log/lsyncd.log",
    statusFile ="/var/log/lsyncd.status",
    inotifyMode = "CloseWrite",
    maxProcesses = 10,
}
sync {
    default.rsync,
    source    = "/var/mg",
    target    = "root@10.1.1.40:/var/mg",
    maxDelays = 5,
    delay = 20,
    excludeFrom = "/root/lsyncd_exclude.lst",
    rsync     = {
        binary = "/usr/bin/rsync",
        archive = true,
        compress = false,
        bwlimit   = 5000,
        -- rsh = "/usr/bin/ssh -p 6622 -o StrictHostKeyChecking=no" –如果ssh非默认端口,需添加此行，同时注意语法问题
        }
    }

　　

4.在客户端上创建lsyncd_exclude.lst并指定exclude的目录

#touch /root/lsyncd_exclude.lst
#echo "mglogs" > /root/lsyncd_exclude.lst

 

5.在客户端上生成SSH密钥对并将公钥CP到备份服务器

#ssh-keygen –t rsa
#scp /root/.ssh/id_rsa.pub  ｛备份服务器IP｝:/root/.ssh/authorized_keys

 

6.在备份服务器上创建目录

#mkdir –p /var/mg

 

7.启动lsyncd进程

#/etc/init.d/lsyncd start
#ps –ef|grep lsyncd 确认进程已启动

　

8.添加开机自启动

#chkconfig rsyncd on
