rsync有个max connections配置段

一年偶尔有几次就不行了；    

报错：

@ERROR: max connections (8) reached - try again later
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(359)

 可以设置大些：

max connections = 25

另外，多台机器同步时候的频率分开些：

比如：

*/1 * * * * /root/rsync.sh

*/2 * * * * /root/rsync.sh

*/3 * * * * /root/rsync.sh
