rsync常用选项

• -a包含-rtplgoD
• -r同步目录时要加上，类似cp时的-r选项
• -v同步时显示一些信息，让我们知道同步的过程
• -l保留软链接
• -L加上该选项后，同步软链接时会把源文件给同步
• -p保持文件的权限属性
• -o保持文件的属主
• -g保持文件的属组
• -D保持设备文件信息
• -t保持文件的时间属性
• --delete删除DEST中SRC没有的文件
• --exclude过滤指定文件，如--exclude "logs"会把文件名包含logs的文件或目录过滤掉，不同步
• -P显示同步过程，比如速率，比-v更加详细
• -u加上该选项后，如果DEST中的文件比SRC新，则不同步
• -z传输时压缩

rsync通过ssh同步

• rsync -av test1/ 192.168.133.132:/tmp/test2/
• rsync -av -e "ssh -p 22" test1/ 192.168.133.132:/tmp/test2/
• rsync通过服务的方式同步
• 要编辑配置文件/etc/rsyncd.conf
• 启动服务rsync --daemon
• 格式：rsync -av test1/ 192.168.133.130::module/dir/
