一、kerberos服务端
-
上传kerberos安装包到/opt/rpm
-
安装:rpm -Uvh --force --nodeps *.rpm
yum -y install krb5-libs krb5-workstation krb5-server
-
修改配置:vi /var/kerberos/krb5kdc/kdc.conf
[kdcdefaults] kdc_ports = 88 kdc_tcp_ports = 88 [realms] HADOOP.COM = { acl_file = /var/kerberos/krb5kdc/kadm5.acl dict_file = /usr/share/dict/words max_life = 24h 0m 0s max_renewable_life = 7d max_life = 1d admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab supported_enctypes = aes256-cts:normal aes128-cts:normal des3-hmac-sha1:normal arcfour-hmac:normal camellia256-cts:normal camellia128-cts:normal des-hmac-sha1:normal des-cbc-md5:normal des-cbc-crc:normal }
[kdcdefaults] kdc_ports = 88 #KDC监听的UDP端口 kdc_tcp_ports = 88 #KDC监听TCP端口 [realms] #使用该KDC的所有域,一个KDC可以支持多个域 HADOOP.COM = { acl_file = /var/kerberos/krb5kdc/kadm5.acl #具有管理服务的用户其访问权限控制文件的位置,默认文件名:kadm5.acl dict_file = /usr/share/dict/words #列举了不允许用做密码的单词,这些单词拥有被破解或猜测 max_life = 1d #票据默认的有效期,默认值是1d max_renewable_life = 7d #票据默认的最大可再生时间,默认是0 admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab #KDC进行校验的keytab。 supported_enctypes = aes256-cts:normal aes128-cts:normal des3-hmac-sha1:normal arcfour-hmac:normal camellia256-cts:normal camellia128-cts:normal des-hmac-sha1:normal des-cbc-md5:normal des-cbc-crc:normal #KDC支持的加密类型 }

修改配置:vi /etc/krb5.conf
# Configuration snippets may be placed in this directory as well includedir /etc/krb5.conf.d/ [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = HADOOP.COM dns_lookup_realm = false ticket_lifetime = 24h renew_lifetime = 7d forwardable = true rdns = false pkinit_anchors = FILE:/etc/pki/tls/certs/ca-bundle.crt udp_preference_limit = 1 # default_realm = EXAMPLE.COM # default_ccache_name = KEYRING:persistent:%{uid} [realms] HADOOP.COM = { kdc = 192.168.248.12 admin_server = 192.168.248.12 } [domain_realm] .hadoop.com = HADOOP.COM hadoop.com = HADOOP.COM

-
初始化数据库:/usr/sbin/kdb5_util create -s -r HADOOP.COM。密码设为:ffcsict1234!#%&
-
查看生成文件:cd /var/kerberos/krb5kdc --> ls
-
创建数据库管理员:/usr/sbin/kadmin.local -q “addprinc admin/admin”,密码为ffcsict1234!#%&
-
管理员设置ACL权限:vi /var/kerberos/krb5kdc/kadm5.acl
*/admin@HADOOP.COM *
-
设置启动和开机自启动:systemctl enable kadmin -->systemctl start kadmin --> systemctl status kadmin
-
设置启动和开机自启动:systemctl enable krb5kdc -->systemctl start krb5kdc --> systemctl status krb5kdc
-
登录管理员:kadmin.local
ps:如果在非服务器上登录管理员,则需要kinit admin/admin -->kadmin
-
管理员操作
ps1-登录:kinit admin/admin --> kadmin。注:如果是在服务端登录,可以直接输入 kadmin.local进入,客户端则如前面。
ps2-查看:listprincs
ps3-创建用户:addprinc 用户名。注:如果需要添加管理员帐户密码。,只需要配置用户名以“/admin”结尾即可,如第7点。
ps4-修改密码:kpasswd 用户名,先输入旧密码,在输入新密码。注:忘记密码,可用kadmin.local登录,change_password 用户名,直接输入新密码。
ps5-删除用户:delprinc 用户名
ps6-查看用户信息:getprinc 用户名
ps7-查看所有命令:?
-
管理员创建kafka用户凭据
在创建用户凭据前 ,需要了解客户端登录的机制有两种。第一种就是使用凭证登录,第二种就是使用账号密码登录。
13.1 使用凭据登录
ps1-创建用户:addprinc -randkey kafka
ps2-创建导出凭据:ktadd -k /root/kerberos/kafka.keytab kafka 或者 xst -k /root/kerberos/kafka.keytab kafka
ps3-查看凭据信息:klist -ket /root/kerberos/kafka.keytab
ps4:将生成的“kafka.keytab”凭据给客户端,客户端可凭借该凭据登录。
13.2 使用账号密码登录
ps1-创建用户:addprinc kafka ,然后输入账号密码即可
ps2:将账号密码给客户端,客户端可以凭借账号密码登录。
ps3-创建凭据:这种方法创建的用户也可以凭借导出凭据登录,但是需要注意的是,在导出凭据的时候需要加上“-randkey ”关键字,否则每次导出密码会变动。这种情况下,只能在服务端的kadmin.local登录环境在操作。 如:ktadd -k /root/kerberos/kafka.keytab -norandkey kafka
-
导出联合凭据:xst -norandkey -k /root/kerberos/kafka.keytab-all kafka kadmin/admin (仅支持服务端的kadmin.local登录环境)
-
将用户信息全部导出: kdb5_util dump ./slava_data,将会生成slava_data 、slava_data.dump_ok两个文件,信息都存在slava_data 里。
二、kerberos客户端
-
下载:yum install -y krb5-lib krb5-workstation krb5-devel krb5-auth-dialog
-
将服务端的/etc/krb5.conf复制到其他节点的/etc底下
-
账号密码登录:kinit admin/admin–>klist
-
删除当前认证用户的缓存:kdestroy --> klist
-
凭据登录:kinit -kt /home/hadoop/kerberos/admin.keytab admin/admin --> klist
三、hadoop集群安装HTTPS服务
安装说明:生成CA证书hdfs_ca_key和hdfs_ca_cert只需要在任意一台节点上完成即可,其他每个节点包括生成证书的节点都需要执行第四步以后的操作,且必须使用root用户执行以下操作
-
在node10节点生成CA证书,需要输入两次密码,其中CN:中国简称;ST:省份;L:城市;O和OU:公司或个人域名;ha01是生成CA证书主机名
openssl req -new -x509 -keyout hdfs_ca_key -out hdfs_ca_cert -days 9999 -subj /C=CN/ST=shanxi/L=xian/O=hlk/OU=hlk/CN=ha01 ffcsict123
-
将node10节点上生成的CA证书hdfs_ca_key、hdfs_ca_cert分发到每个节点上的/tmp目录下
ps:因为我是使用winscp直接拷贝的,如果使用scp指令,建议root用户也配置ssh免登录
scp /opt/https/hdfs_ca_cert root@0001.novalocal:/tmp scp /opt/https/hdfs_ca_key root@0001.novalocal:/tmp
-
发送完成后删除node10节点上CA证书
-
在每一台机器上生成keystore和trustores(注意:集群中每个节点都需要执行以下命令)
1)cd /tmp
2)生成keystore,这里的keytool需要java环境,否则command not found
name="CN=$HOSTNAME, OU=hlk, O=hlk, L=xian, ST=shanxi, C=CN" #需要输入第一步输入的密码四次 keytool -keystore keystore -alias localhost -validity 9999 -genkey -keyalg RSA -keysize 2048 -dname "$name" ffcsict123
3) 添加CA到truststore,同样需要输入密码:keytool -keystore truststore -alias CARoot -import -file hdfs_ca_cert
4)从keystore中导出cert:keytool -certreq -alias localhost -keystore keystore -file cert
5)用CA对cert签名:openssl x509 -req -CA hdfs_ca_cert -CAkey hdfs_ca_key -in cert -out cert_signed -days 9999 -CAcreateserial
6)将CA的cert和用CA签名之后的cert导入keystore
keytool -keystore keystore -alias CARoot -import -file hdfs_ca_cert keytool -keystore keystore -alias localhost -import -file cert_signed
7)将最终keystore,trustores放入合适的目录,并加上后缀jks
mkdir -p /etc/security/https && chmod 755 /etc/security/https cp keystore /etc/security/https/keystore.jks cp truststore /etc/security/https/truststore.jks
8) 删除/tmp目录下产生的垃圾数据文件:rm -f keystore truststore hdfs_ca_key hdfs_ca_cert.srl hdfs_ca_cert cert_signed cert
-
配置$HADOOP_HOME/etc/hadoop/ssl-server.xml和ssl-client.xml文件
注:这两个配置文件在一台节点配好,发送到其他节点对应位置下!
1) :vi /home/hadoop/module/hadoop-3.2.2/etc/hadoop/ssl-client.xml文件

-
拷贝keytab到所有的节点
-
修改所有节点zk的zoo.cfg配置文件:vi /home/hadoop/zookeeper/apache-zookeeper-3.6.3-bin/conf/zoo.cfg
kerberos.removeHostFromPrincipal=true kerberos.removeRealmFromPrincipal=true authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider jaasLoginRenew=3600000
-
生成jaas.conf文件:vi /home/hadoop/zookeeper/apache-zookeeper-3.6.3-bin/conf/jaas.conf
Server { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/home/hadoop/kerberos/hadoop.keytab" storeKey=true useTicketCache=false principal="zookeeper/node10@HADOOP.COM"; }; Client { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/home/hadoop/kerberos/hadoop.keytab" storeKey=true useTicketCache=false principal="hadoop/node10@HADOOP.COM"; };
-
分发到其他节点,需要修改principal
-
配置java.env文件:vi /home/hadoop/zookeeper/apache-zookeeper-3.6.3-bin/conf/java.env
export JVMFLAGS="-Djava.security.auth.login.config=/home/hadoop/zookeeper/apache-zookeeper-3.6.3-bin/conf/jaas.conf"

-
初始化ranger-admin脚本
cd /opt/RangerAdmin/ranger-2.2.0-admin ./setup.sh
-
启动:ranger-admin start
六、kerberos整合hdfs
ps1:如果怕ranger影响安装测试,可以考虑先移除ranger配置,kerberos测试通过后再重新加上ranger配置。可以使用插件自带的脚本disable-hdfs-plugin.sh
ps2:所有节点都要操作
-
修改所有节点core-site.xml配置:vi /home/hadoop/module/hadoop-3.2.2/etc/hadoop/core-site.xml
<!-- 配置kerberos认证 --> <property> <name>hadoop.security.authentication</name> <value>kerberos</value> </property> <property> <name>hadoop.security.authorization</name> <value>true</value> </property> <property> <name>hadoop.rpc.protection</name> <value>authentication</value> </property> <property> <name>hadoop.http.authentication.type</name> <value>kerberos</value> </property>

-
启动hdfs:/home/hadoop/module/hadoop-3.2.2/sbin/start-dfs.sh
-
配置ranger服务
-
新增、并且在ranger web端,配置rangadmin用户所有目录权限
-
验证:首先分发各配置文件
1)票据初始化(每个节点都执行):kinit -kt /home/hadoop/kerberos/hadoop.keytab hadoop/node10
2)使用 klist 命令查看当前是否生成票据,出现有效及过期时间即表示生成票据成功
3)测试:hadoop fs -ls /4)创建zhanzhk用户进行测试(无权限):hadoop fs -ls /
5)hdfs配置zhanzhk权限(看前面文章),再次测试,成功!
七、kerberos整合yarn
ps1:如果怕ranger影响安装测试,可以考虑先移除ranger配置,kerberos测试通过后再重新加上ranger配置。可以使用插件自带的脚本disable-yarn-plugin.sh
ps2:所有节点都要操作
-
配置yarn:vi /home/hadoop/module/hadoop-3.2.2/etc/hadoop/yarn-site.xml
<!-- 配置yarn的web ui 访问https --> <property> <name>yarn.http.policy</name> <value>HTTPS_ONLY</value> </property> <!-- RM1 HTTP访问地址,查看集群信息 --> <property> <name>yarn.resourcemanager.webapp.https.address.rm1</name> <value>node10:8088</value> </property> <!-- RM2 HTTP访问地址,查看集群信息 --> <property> <name>yarn.resourcemanager.webapp.https.address.rm2</name> <value>node11:8088</value> </property> <!-- 配置yarn提交的app程序在hdfs上的日志存储路径 --> <property> <description>Where to aggregate logs to.</description> <name>yarn.nodemanager.remote-app-log-dir</name> <value>/home/hadoop/module/hadoop-3.2.2/logs</value> </property> <!--YARN kerberos security--> <property> <name>yarn.resourcemanager.keytab</name> <value>/home/hadoop/kerberos/hadoop.keytab</value> </property> <property> <name>yarn.resourcemanager.principal</name> <value>hadoop/_HOST@HADOOP.COM</value> </property> <property> <name>yarn.nodemanager.keytab</name> <value>/home/hadoop/kerberos/hadoop.keytab</value> </property> <property> <name>yarn.nodemanager.principal</name> <value>hadoop/_HOST@HADOOP.COM</value> </property> <property> <name>yarn.nodemanager.container-executor.class</name> <value>org.apache.hadoop.yarn.server.nodemanager.LinuxContainerExecutor</value> </property> <!--此处的group为nodemanager用户所属组--> <property> <name>yarn.nodemanager.linux-container-executor.group</name> <value>hadoop</value> </property> <property> <name>yarn.nodemanager.linux-container-executor.path</name> <value>/hdp/bin/container-executor</value> </property>
-
配置yarn:vi /home/hadoop/module/hadoop-3.2.2/etc/hadoop/mapred-site.xml
<!--mapred kerberos security--> <property> <name>mapreduce.jobhistory.keytab</name> <value>/home/hadoop/kerberos/hadoop.keytab</value> </property> <property> <name>mapreduce.jobhistory.principal</name> <value>hadoop/_HOST@HADOOP.COM</value> </property> <property> <name>mapreduce.jobhistory.http.policy</name> <value>HTTPS_ONLY</value> </property> <property> <name>mapreduce.jobhistory.webapp.https.address</name> <value>node10:19888</value> </property> <property> <name>mapreduce.ssl.enabled</name> <value>true</value> </property> <property> <name>mapreduce.shuffle.ssl.enabled</name> <value>true</value> </property>
-
分发修改的配置文件至各节点
-
配置container-executor:vi /home/hadoop/module/hadoop-3.2.2/etc/hadoop/container-executor.cfg
ps:注意:该container-executor.cfg文件内不允许有空格或空行,否则会报错!
#configured value of yarn.nodemanager.linux-container-executor.group yarn.nodemanager.linux-container-executor.group=hadoop #comma separated list of users who can not run applications banned.users=mysql #Prevent other super-users min.user.id=500 #comma separated list of system users who CAN run applications allowed.system.users=root
-
配置Yarn使用LinuxContainerExecutor(各节点都需要操作)
1)创建文件夹:mkdir -p /hdp/bin、mkdir -p /hdp/etc/hadoop
2)拷贝文件:
cp /home/hadoop/module/hadoop-3.2.2/bin/container-executor /hdp/bin/container-executor cp /home/hadoop/module/hadoop-3.2.2/etc/hadoop/container-executor.cfg /hdp/etc/hadoop/container-executor.cfg
3)修改权限:
chown -R root:hadoop /hdp/bin/container-executor chown -R root:hadoop /hdp/etc/hadoop/container-executor.cfg chown -R root:hadoop /hdp/bin chown -R root:hadoop /hdp/etc/hadoop chown -R root:hadoop /hdp/etc chown -R root:hadoop /hdp chmod 6050 /hdp/bin/container-executor
-
测试:hadoop checknative
-
/hdp/bin/container-executor --checksetup,没输出东西说明正常
-
拷贝密钥:cp /home/hadoop/kerberos/hadoop.keytab /home/hadoop/hadoop.keytab
-
启动start-yarn.sh(root用户):/home/hadoop/module/hadoop-3.2.2/sbin/start-yarn.sh
-
验证(无权限):
1. kinit -kt /home/hadoop/kerberos/hadoop.keytab zhanzhk/node10 2. hadoop jar /home/hadoop/module/hadoop-3.2.2/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.2.2.jar pi -Dmapred.job.queue.name=default 2 2
-
修改rangeryarn服务
ps:此时点击连接测试会报错,忽略即可
Unable to retrieve any files using given parameters, You can still save the repository and start creating policies, but you would not be able to use autocomplete for resource names. Check ranger_admin.log for more info. org.apache.ranger.plugin.client.HadoopException: Unable to get a valid response for expected mime type : [application/json] URL : https://node10:8088,https://node11:8088. Unable to get a valid response for expected mime type : [application/json] URL : https://node10:8088,https://node11:8088 - got null response.. ```
-
配置添加zhanzhk账户策略即可!
-
重新测试,成功!
八、kerberos整合hive
ps1:如果怕ranger影响安装测试,可以考虑先移除ranger配置,kerberos测试通过后再重新加上ranger配置。可以使用插件自带的脚本disable-hive-plugin.sh
同时需要移除/home/hadoop/module/hive/conf/hiveserver2-site.xml配置文件。
-
配置hive-site.xml:vi /home/hadoop/module/hive/conf/hive-site.xml
<property> <name>hive.server2.enable.doAs</name> <value>true</value> </property> <property> <name>hive.server2.authentication</name> <value>KERBEROS</value> </property> <property> <name>hive.server2.authentication.kerberos.principal</name> <value>hadoop/_HOST@HADOOP.COM</value> </property> <property> <name>hive.server2.authentication.kerberos.keytab</name> <value>/home/hadoop/kerberos/hadoop.keytab</value> </property> <property> <name>hive.server2.authentication.spnego.keytab</name> <value>/home/hadoop/kerberos/hadoop.keytab</value> </property> <property> <name>hive.server2.authentication.spnego.principal</name> <value>hadoop/_HOST@HADOOP.COM</value> </property> <property> <name>hive.metastore.sasl.enabled</name> <value>true</value> </property> <property> <name>hive.metastore.kerberos.keytab.file</name> <value>/home/hadoop/kerberos/hadoop.keytab</value> </property> <property> <name>hive.metastore.kerberos.principal</name> <value>hadoop/_HOST@HADOOP.COM</value> </property> <!--配置hiveserver2高可用--> <property> <name>hive.server2.support.dynamic.service.discovery</name> <value>true</value> </property> <property> <name>hive.server2.zookeeper.namespace</name> <value>hiveserver2_zk</value> </property> <property> <name>hive.zookeeper.quorum</name> <value> node10:2181,node11:2181,node12:2181</value> </property> <property> <name>hive.zookeeper.client.port</name> <value>2181</value> </property>
-
修改core-site.xml配置文件:vi /home/hadoop/module/hadoop-3.2.2/etc/hadoop/core-site.xml
<property> <name>hadoop.proxyuser.hive.users</name> <value>*</value> </property> <property> <name>hadoop.proxyuser.hive.hosts</name> <value>*</value> </property>
-
赋权:chown hadoop:hadoop /home/hadoop
-
启动hive客户端:cd /home/hadoop/module/hive —》 nohup ./bin/hiveserver2>> hiveserver2.log 2>&1 &
-
连接测试:
ps:beeline连接必须使用配置文件配置的Hadoop连接,如下。如果想要区分用户,需要根据kinit用户进行区分
kinit -kt /home/hadoop/kerberos/hadoop.keytab zhanzhk/node10 beeline -u "jdbc:hive2://node10:10000/default;principal=hadoop/node10@HADOOP.COM" create table zk(id int,name String); insert into zk values('4', 'abc222'); show tables;
报错无权限:Error: Error while compiling statement: FAILED: HiveAccessControlException Permission denied: user [zhanzhk] does not have [USE] privilege on [default] (state=42000,code=40000)
-
重新配置hive的service
-
设置用户策略
-
保存,然后回到service点击test,显示成功即可
-
重新连接测试:成功!
kinit -kt /home/hadoop/kerberos/hadoop.keytab zhanzhk/node10 beeline -u "jdbc:hive2://node10:10000/default;principal=hadoop/node10@HADOOP.COM" create table zk(id int,name String); insert into zk values(13,'小红'); show tables; beeline -u "jdbc:hive2://0003.novalocal:10000/default;principal=hadoop/node10@HADOOP.COM" bin/beeline -u jdbc:hive2://0003.novalocal:10000/default -n root -p ffcsict123 create table sqoop_test(id int,name String,age int,address String,phone String); insert into sqoop_test values(13,'小红',18,'连花村','18854523654');
九、kerberos整合hbase
ps1:如果怕ranger影响安装测试,可以考虑先移除ranger配置,kerberos测试通过后再重新加上ranger配置。可以使用插件自带的脚本disable-hbase-plugin.sh
-
修改hbase-site.xml配置:vi /home/hadoop/hbase/hbase-2.1.0/conf/hbase-site.xml
<!-- hbase配置kerberos安全认证 --> <property> <name>hbase.security.authentication</name> <value>kerberos</value> </property> <!-- 配置hbase rpc安全通信 --> <property> <name>hbase.rpc.engine</name> <value>org.apache.hadoop.hbase.ipc.SecureRpcEngine</value> </property> <property> <name>hbase.coprocessor.region.classes</name> <value>org.apache.hadoop.hbase.security.token.TokenProvider</value> </property> <!-- hmaster配置kerberos安全凭据认证 --> <property> <name>hbase.master.kerberos.principal</name> <value>hadoop/_HOST@HADOOP.COM</value> </property> <!-- hmaster配置kerberos安全证书keytab文件位置 --> <property> <name>hbase.master.keytab.file</name> <value>/home/hadoop/kerberos/hadoop.keytab</value> </property> <!-- regionserver配置kerberos安全凭据认证 --> <property> <name>hbase.regionserver.kerberos.principal</name> <value>hadoop/_HOST@HADOOP.COM</value> </property> <!-- regionserver配置kerberos安全证书keytab文件位置 --> <property> <name>hbase.regionserver.keytab.file</name> <value>/home/hadoop/kerberos/hadoop.keytab</value> </property>
-
创建文件:vi /home/hadoop/hbase/hbase-2.1.0/conf/zk-jaas.conf
Client { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/home/hadoop/kerberos/hadoop.keytab" useTicketCache=false principal="hadoop/node10@HADOOP.COM"; };
-
修改hbase-site.xml配置:vi /home/hadoop/hbase/hbase-2.1.0/conf/hbase-env.sh
#修改HBASE_OPTS属性为该内容 export HBASE_OPTS="-XX:+UseConcMarkSweepGC -Djava.security.auth.login.config=/home/hadoop/hbase/hbase-2.1.0/conf/zk-jaas.conf"
-
赋权:chown hadoop:hadoop /home/hadoop
-
重启
-
测试(无权限):
kinit -kt /home/hadoop/kerberos/hadoop.keytab zhanzhk/node10 cd /home/hadoop/hbase/hbase-2.1.0/bin ./hbase shell hive测试指令: 1. create 'B_TEST_STU','cf' 2. 插入数据:put 'B_TEST_STU','001','cf:age','17' 3. 查看表数据: scan 'B_TEST_STU'
-
重新配置hbase的service
-
测试连接
-
重新测试创建表
kinit -kt /home/hadoop/kerberos/hadoop.keytab zhanzhk/node10 cd /home/hadoop/hbase/hbase-2.1.0/bin ./hbase shell hbase测试指令: 1. create 'B_TEST_STU','cf' 2. 插入数据:put 'B_TEST_STU','001','cf:age','17' 3. 查看表数据: scan 'B_TEST_STU'
-
成功!
十、遇到的问题
-
用户找不到
问题:main : requested yarn user is zhanzhk,User zhanzhk not found。且kdc服务器已经创建了zhanzhk用户
解决:在所有节点创建zhanzhk用户,useradd zhanzhk
-
KeeperErrorCode = AuthFailed fo XXXXX
解决:zookeeper整合kerberos即可
-
RM could not transition to Active
删除tmp底下的yarn相关文件夹即可
