如何使用 lsyncd 实时同步并执行 shell 命令

修改 lsyncd 的默认配置，不直接执行rsync 进行同步，而是改用自己的脚本。

binary 指定我们的脚本

vim /usr/local/lsyncd/etc/lsyncd.conf

settings  {
   logfile = "/usr/local/lsyncd/logs/lsyncd.log",
   statusFile = "/usr/local/lsyncd/logs/lsyncd.status",
   maxDelays = 100,
   statusInterval = 5,
   delay = 5,
   exitcodes = {[0] = "ok", [1] = "again", [2] = "die"}

   }
sync {
    default.rsync,
    source    = "/data/logs/nginx",
    target    = "sync_user@192.168.31.140::sync_test",
    exclude   = { ".*", "*.tmp", "*.bak" , "*.pid"},
    delete    = true,
    rsync     = {
        binary = "/data/sh/mysync.sh",
        compress = false,
        archive  = true,
        verbose  = false,
        timeout  = 3600,
        password_file = "/usr/local/lsyncd/etc/rsync.pass"
    }
}

编写自己的脚本

vim /data/sh/mysync.sh

#!/bin/bash
/usr/bin/rsync "$@"
result=$?
args="$@"
(
  if [ $result -eq 0 ]; then
     echo "argument：$args" >> /tmp/lsync_test.txt
  fi
) >/dev/null 2>/dev/null </dev/null

exit $result

lsyncd 会调用 /data/sh/mysync.sh 脚本触发 rsync 同步，并执行脚本后续的命令。
