lsyncd 文件同步配置文件配置

实现多台服务器服务器之间的文件同步

安装步骤

yum install epel-release -y
yum install lsyncd -y

2台服务器之间做免密操作

ssh-keygen -t rsa -b 2048
ssh-copy-id username@remote_host

配置lsyncd     /etc/lsyncd.conf

A服务器配置：

settings {
logfile = "/var/log/lsyncd/lsyncd.log",
statusFile = "/var/run/lsyncd/lsyncd.status",
statusInterval = 20,
}

sync {
default.rsyncssh,
source = "/root/a/",
host = "root@192.168.249.33",
targetdir = "/root/b/",
ssh = {
port = 22,
},
rsync = {
archive = true,
compress = true,
verbose = true,
},
delay = 5,
}

B服务器配置:

settings {
logfile = "/var/log/lsyncd/lsyncd.log",
statusFile = "/var/run/lsyncd/lsyncd.status",
statusInterval = 20,
}

sync {
default.rsyncssh,
source = "/root/b/",
host = "root@192.168.249.34",
targetdir = "/root/a/",
ssh = {
port = 22,
},
rsync = {
archive = true,
compress = true,
verbose = true,
},
delay = 5,
}

启动服务

systemctl restart lsyncd

效果展示

 

单台服务器目录同步

settings {
    logfile    = "/var/log/lsyncd/lsyncd.log",
    statusFile = "/tmp/lsyncd.status",
    inotifyMode = "CloseWrite or Modify",
}

sync {
    default.direct,
    source = "/root/A/",
    target = "/root/B"
}
