# nodetool repair 顾名思义就是修复，这是nodetool中一个非常重要的操作。当我们对数据有修改或删除动作时，或定期执行repair操作，以保持各个节点的一致性。 #

基本格式

nodetool \[(-h <host> | --host <host>)\] \[(-p <port> | --port <port>)\]  
     \[(-pw password | --password password)\]  
     \[(-pwf passwordFilePath | --password-file passwordFilePath)\]  
     \[(-u username | --username username)\] **repair**  
     \[(-dc specific\_dc | --in-dc specific\_dc)...\]  
     \[(-dcpar | --dc-parallel)\] \[(-et end\_token | --end-token end\_token)\]  
     \[(-full | --full)\]  
     \[(-hosts specific\_host | --in-hosts specific\_host)...\]  
     \[(-j job\_threads | --job-threads job\_threads)\]  
     \[(-local | --in-local-dc)\] \[(-pr | --partitioner-range)\]  
     \[(-seq | --sequential)\]  
     \[(-st start\_token | --start-token start\_token)\] \[(-tr | --trace)\]  
     \[--\] \[keyspace tables...\]

**这里要注意的是这些参数是有顺序的，有些只能在repair，有些只能在repair后，哥一开始没注意这些顺序，走了很多弯路。**

示例：

在当前节点,顺序修复所有的keyspaces  
**./nodetool repair -seq**  
  
  
修复当前所在的数据中心(data\_center)，该命令只能在当前数据中心使用。  
**./nodetool repair -dc DC1**  
  
  
如果想修复某一段ring的数据(相对于全部修复,话费时间更少)，就用-st(即start\_token) -et(即end\_token),这对token必须是同一个node,且有大小顺序。查看ring的命令用**repair ring**

**./nodetool repair -st 7521963415957825786 -et 8097903535872843286**  
  
  
只修复range落在该节点的master数据  
**./nodetool repair -pr**
