安装配置文件

 

echo "1" > /data/zookeeper/myid

在每个节点配置环境变量/etc/profile

#Set ZOOKEEPER_HOME ENVIRONMENT export ZOOKEEPER_HOME=/data/apps/zookeeper-3.4.12 export PATH=$PATH:$ZOOKEEPER_HOME/bin

修改日志输入目录：

参考： https://blog.csdn.net/dehu_zhou/article/details/81939965

加入开机启动

[root@computer9 ~]# vim /etc/rc.local // 写到这个文件的路经一定要写绝对路径

/data/apps/zookeeper-3.4.13/bin/zkServer.sh start /data/apps/zookeeper-3.4.13/conf/zoo.cfg >> /tmp/zookeeper_start.log

 

zkCli.sh -server 192.168.1.71:2181,192.168.1.81:2181,192.168.1.91:2181

./zkCli.sh -server computer7:2181,computer8:2181,computer9:2181

./zkCli.cmd -server computer7:2181,computer8:2181,computer9:2181

安装配置kerberos认证

https://blog.csdn.net/lovebomei/article/details/79807484

vim bin/zkEnv.sh ZOO_LOG_DIR="$ZOOKEEPER_PREFIX/logs" ZOO_LOG4J_PROP="INFO,ROLLINGFILE" vim bin/zkServer.sh _ZOO_DAEMON_OUT="$ZOO_LOG_DIR/zookeeper.log" vim conf/log4j.properties zookeeper.root.logger=INFO, ROLLINGFILE zookeeper.log.dir=/data/apps/zookeeper-3.4.13 zookeeper.tracelog.dir=/data/zookeeper_data zookeeper.tracelog.file=zookeeper_trace.log

KDCE服务端安装

选择一个主机来运行KDC，并在该主机上安装krb-5libs,krb5-server

yum install krb5-server krb5-libs krb5-auth-dialog

vim /var/kerberos/krb5kdc/kdc.conf

[kdcdefaults]

kdc_ports = 88

kdc_tcp_ports = 88

[realms]

HADOOP.COM = {

#master_key_type = aes256-cts

acl_file = /var/kerberos/krb5kdc/kadm5.acl

dict_file = /usr/share/dict/words

admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab

supported_enctypes = aes128-cts:normal des3-hmac-sha1:normal arcfour-hmac:normal des-hmac-sha1:normal des-cbc-md5:normal des-cbc-crc:normal

}

 

vim /etc/krb5.conf 所有客户端都要配置。

[root@computer6 /]# cat /etc/krb5.conf

[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

dns_lookup_kdc = false

ticket_lifetime = 24h

renew_lifetime = 7d

forwardable = true

 

[realms]

EXAMPLE.COM = {

kdc = computer6

admin_server = computer6

}

 

[domain_realm]

.example.com = HADOOP.COM

example.com = HADOOP.COM

[root@computer6 /]#

 

在maste KDC上执行：

[root@vmw201 /]# /usr/sbin/kadmin.local -q "addprinc admin/admin" 并为其设置密码

 

我们现在为administrator设置权限：将文件/var/kerberos/krb5kdc/kadm5.acl的内容编辑为

*/[email protected] *

代表名称匹配/[email protected] 都认为是admin，权限是 。代表全部权限。

 

在master KDC启动Kerberos daemons

手动启动：

[root@vmw201 /]# service krb5kdc start

[root@vmw201 /]# service kadmin start

设置开机自动启动：

[root@vmw201 /]# chkconfig krb5kdc on

[root@vmw201 /]# chkconfig kadmin on

 

在另外两台主机安装kerberos客户端。

yum install krb5-workstation krb5-libs krb5-auth-dialog

 

配置krb5.conf

配置这些主机上的/etc/krb5.conf，这个文件的内容与KDC中的文件保持一致即可。

 

/usr/sbin/kdb5_util create -s -r HADOOP.COM //创建数据库

/usr/sbin/kadmin.local -q "addprinc admin/admin"

 

Zookeeper集群安装-开启kerberos

https://www.jianshu.com/p/ca78a43ec107

addprinc -randkey zookeeper/[email protected]

addprinc -randkey zookeeper/[email protected]

addprinc -randkey zookeeper/[email protected]

 

xst -k zookeeper.keytab zookeeper/[email protected]

xst -k zookeeper.keytab zookeeper/[email protected]

xst -k zookeeper.keytab zookeeper/[email protected]

 

addAcl /mynode sasl:zookeeper/[email protected]:cdrwa 设置节点权限

vim zoo.cfg

authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider jaasLoginRenew=3600000 kerberos.removeHostFromPrincipal=true kerberos.removeRealmFromPrincipal=true

vim /etc/profile

export JVMFLAGS="-Djava.security.auth.login.config=/data/apps/zookeeper-3.4.13/conf/jaas.conf"

 

 

vim jaas.conf

Server { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/data/apps/zookeeper-3.4.13/conf/zookeeper.keytab" storeKey=true useTicketCache=false principal="zookeeper/[email protected]"; }; Client { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/data/apps/zookeeper-3.4.13/conf/zookeeper.keytab" storeKey=true useTicketCache=false principal="zookeeper/[email protected]"; };

去除认证

去除认证时要把zookeeper-3.4.13/conf/*下的认证文件删除，不然启动时报如下错误
