add below

to make line 141 looks like

7. commands 
#start

8. 为安装solr 作准备 create /solr node 
9. add auth 
       cd /opt/my_work/my_tools/zookeeper/current/bin 
       sh zkCli.sh 

addauth digest super:my_zookeeper  -- to run as super 
setAcl /solr digest:zk_solr:zwa+EAl8ISxlMCXhxjKNgMfw/a4=:crwda,digest:zk_solr_read:78hARJi0TFVA3LUYDgEqFkT/McU=:r   -- 一次设置两个acl 
-- zk_solr:zk_solr_super , zk_solr_read:zk_solr_read 

注: 可以用zookeeper自带的Java客户端中的类：org.apache.zookeeper.server.auth.DigestAuthenticationProvider 来生成这个digest配置
import org.apache.zookeeper.server.auth.DigestAuthenticationProvider; 

public class EncryptPasswdTest  { 
public static void main(String[] args) throws Exception{ 
String plainDigest = "zk_solr_read:zk_solr_read"; 
String encypted = DigestAuthenticationProvider.generateDigest(plainDigest); 
System.out.println(encypted); 
} 
} 

设置保护/solr 节点的密码，在solr中配置的是super，因为上面两个帐号只针对 节点 /solr 本身，对/solr的字节点不起作用
