一、zookeeper配置

1、conf/zk_server_jaas.conf
##DIGEST-MD5 authentication
Server {
       org.apache.zookeeper.server.auth.DigestLoginModule required
       user_super="adminsecret" #用户为super，密码为adminsecret
       user_bob="bobsecret";
};

Client {
       org.apache.zookeeper.server.auth.DigestLoginModule required
       username="bob"
       password="bobsecret";
};
注意Server和Client在用户和密码配置之间的区别

2、conf/java.env
CLIENT_JVMFLAGS="${CLIENT_JVMFLAGS} -Djava.security.auth.login.config=/path/to/client/jaas/file.conf"
SERVER_JVMFLAGS="-Djava.security.auth.login.config=/path/to/server/jaas/file.conf \
-Dzookeeper.authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider \
-Dzookeeper.requireClientAuthScheme=sasl \
-Dzookeeper.jaasLoginRenew=3600000 \
-Dzookeeper.zookeeper.sasl.client=true \
-Dzookeeper.allowSaslFailedClients=false \
-Dzookeeper.sessionRequireClientSASLAuth=true \
"

3、启动zookeeper即可

二、zookeeper强制开启sasl

1、requireClientAuthScheme=sasl
单纯这一行并不顶用，客户端依旧可以以非sasl的方式登录

2、参数
allowSaslFailedClients=false
sessionRequireClientSASLAuth=true
这俩参数可以控制客户端必须以sasl连接，如果非sasl连接，无法做任何操作
