lsyncd实时同步工具安装

有2种方法可以安装

1.yum安装，前提是安装了epel更新源。使用命令：

yum install -y lsyncd

2.github下载，地址为：https://github.com/axkibe/lsyncd

安装lua软件包以及依赖软件

yum install -y lua lua-devel cmake rsync

解压下载的压缩包

unzip lsyncd-master.zip -d /usr/src/

进入目录

cd /usr/src/lsyncd-master/

使用cmake编译，如果没有安装cmake,可以yum安装一下

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/lsyncd

make && make install

进入安装目录

cd /usr/local/lsyncd/

mkdir etc var

进入配置文件目录

cd etc/

编译配置文件

vim lsyncd.conf

settings {

 --pid文件

 logfile = "/usr/local/lsyncd/var/lsyncd.log",

 --状态文件

 statusFile = "/usr/local/lsyncd/var/lsyncd.status",

 --同步模式，意思就是有更新就同步

 inotifyMode = "CloseWrite or Modify",

 --最大8个进程

    maxProcesses = 8,

}

sync {
    default.rsync,
    source    = "/www",
    target    = "root@192.168.10.50:/www",
    maxDelays = 5,
    delay = 30,
    -- init = true,
    rsync     = {
        binary = "/usr/bin/rsync",
        archive = true,
        compress = true,
        bwlimit   = 2000
        -- rsh = "/usr/bin/ssh -p 22 -o StrictHostKeyChecking=no"
        }
    }

在远端被同步的服务器上开启ssh无密码登录，请注意用户身份：（用root还是最吼的！！！）

链接：ssh免密码登录

最后启动

/usr/local/lsyncd/bin/lsyncd -log Exec /usr/local/lsyncd/etc/lsyncd.conf

关闭

 ps -aux | grep lsyncd
kill id

编译启动脚本

vim /etc/init.d/lsyncd

#!/bin/bash

#

# chkconfig: - 85 15

        echo $"Usage: $0 {start|stop|status|restart|condrestart|reload}"

        RETVAL=1

esac



exit $RETVAL

设置权限

chmod 755 /etc/init.d/lsyncd

添加到开机自启动文件中

echo "/etc/init.d/lsyncd start" >> /etc/rc.local
