Ubuntu
#
sudo apt-get update
sudo apt-get install lsyncd
CentOS
#
yum -y update
yum -y install lsyncd
Running these commands will install Lsyncd as well as include some examples within the following directory /usr/share/doc/lsyncd/examples. These examples can be used to help get a better idea of the configuration possibles when using this synchronization method.
Setting up lsyncd over SSH with KeyCDN
#
Before getting started, you must first ensure that you have uploaded your public SSH key to the KeyCDN dashboard and added your private key on your system using ssh-add /path/to/your/private.key. If you do not yet have an SSH key pair, see our article on How to: Create SSH Key.
Once you have properly set up your SSH keys you can begin configuring your environment. To do this you must create lsyncd.log and lsyncd-status.log files in these respective directories
/var/log/lsyncd/lsyncd.log
and
/var/log/lsyncd/lsyncd-status.log
Once this is complete, you can then begin to set up your configuration file. There is no default configuration file, however you can create one in your /etc/lsyncd/lsyncd.conf.lua directory on your local machine and add the following information.
settings {
-- 日志文件存放位置
logfile = "/var/log/lsyncd/lsyncd.log",
-- 监控目录状态文件的存放位置
statusFile = "/var/log/lsyncd/lsyncd-status.log",
-- 指定要监控的事件,如,CloseWrite,Modify,CloseWrite or Modify
inotifyMode = "CloseWrite or Modify",
-- 指定同步时进程的最大个数
maxProcesses = 10,
-- 隔多少秒记录一次被监控目录的状态
statusInterval = 10
-- false=启用守护模式
nodaemon = false,
-- 当事件被命中累计多少次后才进行一次同步(即使间隔低于statusInterval)
-- maxDelays = 20
}
-- 将 本地/home/temp/ 推送到 47.91.228.160:/var/log/nginx/ 目录
sync {
-- lsyncd运行模式
-- default.direct=本地目录间同步
-- default.rsync=使用rsync
-- default.rsyncssh=使用rsync的ssh模式
default.rsync,
-- 同步的源目录
source="/home/temp/",
-- 同步的目标目录
target="[email protected]:/var/log/nginx/",
-- 是否同步删除 true=同步删除 false=增量备份
delete = false,
-- 忽略文件路径规则，可用table也可用外部配置文件
-- excludeFrom = "/etc/lsyncd_exclude.lst",
exclude = {
".*",
".svn",
".git",
},
-- 排除同步文件
exclude = { ".*" },
-- 等待rsync同步延时时间(秒)
delay = 5,
-- init=false则只同步lsyncd启动后变更，不设置则lsyncd启动后进行全量的同步
--init = True,
rsync = {
archive = false,
acls = false,
chmod = "D2755,F644",
compress = true,
links = false,
owner = false,
perms = false,
verbose = true,
rsh = "/usr/bin/ssh -p 22 -o StrictHostKeyChecking=no"
}
}
通过 Rsync 配置的范本
rsync = {
-- 单位kb
bwlimit=1000,
binary = "/usr/bin/rsync",
archive = true,
compress = true,
verbose = true,
perms = true,
-- rsync的用户密码，不是Linux系统的用户密码
password_file = "/etc/lsyncd/rsync.passwd"
}
重启服务
service lsyncd restart
