4.zookeeper节点 *** 作，权限

输入help命令，看到zk的所有命令
创建和查看节点

create [-s] [-e] [-c] [-t ttl] path [data] [acl]
get [-s] [-w] path
ls [-s] [-w] [-R] path

删除节点

delete /test1
#乐观锁 带版本号删除，版本号不匹配返回 version No is not valid : /test
delete -v 0 /test1
deleteall /test1

权限控制，当前会话设置权限账号zhangsan密码123456，创建test节点

[zk: localhost:2181(CONNECTED) 30] addauth digest zhangsan:123456
[zk: localhost:2181(CONNECTED) 31] create /test abc auth:zhangsan:123456:cdrwa
Created /test
[zk: localhost:2181(CONNECTED) 32] get /test
abc

新开一个会话访问test节点，报错没权限org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth for /test

[zk: localhost:2181(CONNECTED) 0] ls /
[test, test10000000008, test10000000009, test10000000010, test20000000002, test20000000003, test20000000004, test20000000005, test20000000006, zookeeper]
[zk: localhost:2181(CONNECTED) 1] get /test
org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth for /test

设置权限addauth digest zhangsan:123456后才可以才做查看 *** 作

[zk: localhost:2181(CONNECTED) 2] addauth digest zhangsan:123456
[zk: localhost:2181(CONNECTED) 3] get /test
abc
