安装Metron

1.Metron简介

Metron是一种多功能的安全遥测数据捕获、流分析和威胁响应平台,最早由Cisco公司的开源大数据系统安全框架项目OpenSOC迁移为Metron项目,现已晋升为Apache顶级项目。Metron提供的功能包括:日志的聚合、对网络包全面捕获的索引和存储、高级行为分析及数据浓缩,并可以将当前的威胁情报信息应用到安全遥测中。从概念上可划分为四个组件:数据捕获与摄取、实时数据处理、受保证的数据持久化和存储、用于驱动监控和风险报警服务的机器学习模型。

2.Metron架构及功能

 

3.安装Metron

1)基础环境及版本

       CentOS 7

       Metron 0.4.1

       HDP 2.5

Hosts:
192.168.11.90  node1
192.168.11.103 node2
192.168.11.104 node3

1)添加epel repository 并更新系统:

yum install epel-release -y
yum update -y

2)配置各节点间的免秘钥登录,具体参考:https://mp.csdn.net/postedit/81384217

3)在将要安装ES和Storm的节点上增加ElasticSearch和Storm的限制(若不确定安装节点,则在所有节点上增加限制)

echo -e "elasticsearch - memlock unlimited\nstorm - nproc 257597" >> /etc/security/limits.conf

4)调整限制以确保安全级别

ulimit -n 32768
ulimit -u 65536
echo -e "* - nofile 32768\n* - nproc 65536" >> /etc/security/limits.conf

5)禁用IPv6,启用它可能会强制服务仅绑定到IPv6地址,从而导致无法连接到IPv6

sysctl -w net.ipv6.conf.all.disable_ipv6=1
sysctl -w net.ipv6.conf.default.disable_ipv6=1
echo -e "\n# Disable IPv6\nnet.ipv6.conf.all.disable_ipv6 = 1\nnet.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf

6)禁用Transparent Hugepage(Transparent HugePages是RHEL6的新特性)

在kernel配置文件(/etc/ default / grub)的末尾添加“transparent_hugepage = never”,并重新启动(reboot)。

# 修改行:
GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=cl/root rd.lvm.lv=cl/swap rhgb quiet"
# 为:
GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=cl/root rd.lvm.lv=cl/swap rhgb quiet transparent_hugepage=never"

之后,执行:

grub2-mkconfig -o /boot/grub2/grub.cfg

重启后检查是否已应用更改(确保在方括号中选择“never”字样)

cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]

备注:若不想搞乱内核参数,可以创建一个新的systemd服务,在每次启动时禁用它。方法如下:

          创建文件“/etc/systemd/system/disable-thp.service”:

[Unit]
Description=Disable Transparent Huge Pages (THP)
 
[Service]
Type=simple
ExecStart=/bin/sh -c "echo 'never' > /sys/kernel/mm/transparent_hugepage/enabled && echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag"
 
[Install]
WantedBy=multi-user.target

       重新启动systemd,启动新服务并确保新服务在启动时运行:

# systemctl daemon-reload
# systemctl start disable-thp
# systemctl enable disable-thp

7)禁用SELinux(Ambari和Metron必需条件):

setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

Metron安装准备

(1)在所有节点上安装Ambari的先决条件:


yum install git wget curl rpm tar unzip scp bzip2 wget createrepo yum-utils ntp python-pip psutils python-psutil ntp libffi-devel gcc openssl-devel -y
pip install --upgrade pip
pip install requests

备注:yum 安装 scp 报错:

安装Metron_第1张图片

原因:yum 不存在独立的scp 包,scp属于openssh-clients这个包。

解决方案:安装openssh-clients 即可

yum install openssh-clients

(2)在Metron节点上安装java 1.8(若不确定Metron安装节点,在所有节点上安装Java1.8):

yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel -y

(3)设置Java环境变量:

export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s_/jre/bin/java__")

(4)保存java环境变量,以备重启时使用:

echo 'export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s_/jre/bin/java__")' > /etc/profile.d/java_18.sh
chmod +x /etc/profile.d/java_18.sh
source /etc/profile.d/java_18.sh

(5)下载并安装Maven 3.3.9:

wget https://archive.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
tar -zxf apache-maven-3.3.9-bin.tar.gz
mv apache-maven-3.3.9 /opt
PATH=/opt/apache-maven-3.3.9/bin:$PATH
echo 'export PATH=/opt/apache-maven-3.3.9/bin:$PATH' > /etc/profile.d/maven.sh
chmod +x /etc/profile.d/maven.sh

(6)检查Maven是否安装成功:

source /etc/profile.d/maven.sh
mvn -V

若安装成功,执行结果如下:

# mvn -V
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T08:41:47-08:00)

(7) 在Ambari节点上安装并启用docker(需要使用docker为Ambari创建Metron包)

yum install docker-io -y
systemctl start docker

(8)在打包节点上安装nmp,这是构建metron-config所必需的,它是UI的一部分。

yum install npm -y

(9)在 /etc/hosts文件中添加:

127.0.0.1 localhost

(10)在主节点上安装数据库,以备Metron REST使用:

yum install mariadb-server -y

(11) 在所有节点上安装JAVA MySQL连接器:

yum install mysql-connector-java -y

配置Metron REST数据库

安装数据库后运行"mysql_secure_installation"进行初始安全设置:

systemctl start mariadb
systemctl enable mariadb
systemctl status mariadb
mysql_secure_installation # 

打包 Metron code

1)从github上克隆Metron repo并切换到0.4.1版本:

git clone https://github.com/apache/metron
cd metron
git checkout Metron_0.4.1

2)使用HDP 2.5构建Metron:

cd metron
mvn clean package -DskipTests -T 2C -P HDP-2.5.0.0,mpack
cd metron-deployment/packaging/docker/rpm-docker
mvn clean install -DskipTests -PHDP-2.5.0.0

     备注:如果rpm-docker失败并报错如下:

/bin/bash:./build.sh:Permission denied

       请禁用selinux后重试 

3)在所有节点上,创建localrepo目录并从Ambari节点复制RPM:


mkdir /localrepo
cp -rp /root/metron/metron-deployment/packaging/docker/rpm-docker/RPMS/noarch/* /localrepo/
createrepo /localrepo

       备注:如果多节点安装,还要将软件包复制到其他节点:

ssh root@node2 mkdir /localrepo
scp /localrepo/*rpm root@node2:/localrepo/
ssh root@node2 createrepo /localrepo

4) 为Hadoop服务获取并创建logrotate脚本:

wget -O /etc/logrotate.d/metron-ambari https://raw.githubusercontent.com/apache/metron/master/metron-deployment/roles/ambari_common/templates/metron-hadoop-logrotate.yml
sed -i 's/^  {{ hadoop_logrotate_frequency }}.*$/  daily/' /etc/logrotate.d/metron-ambari
sed -i 's/^  rotate {{ hadoop_logrotate_retention }}.*$/  rotate 30/' /etc/logrotate.d/metron-ambari
chmod 0644 /etc/logrotate.d/metron-ambari

安装Ambari

(1)首先,在每个节点上时间同步,禁用防火墙和SElinux

systemctl enable ntpd
systemctl start ntpd
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -t nat -F
iptables -t mangle -F
iptables -F
iptables -X
iptables-save > /etc/sysconfig/iptables
systemctl stop firewalld
systemctl disable firewalld
setenforce 0

备注:如果使用的是CentOS 7和Python 2.7.5及更高版本,则在Ambari UI中安装ambari代理时会遇到错误:

[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:579)

解决办法:要修复它,请在Python中禁用cert检查

参考:https://community.hortonworks.com/questions/120861/ambari-agent-ssl-certificate-verify-failed-certifi.html

sed -i 's/verify=platform_default/verify=disable/' /etc/python/cert-verification.cfg

(2)确保每个节点都可以解析每个其他节点的主机名,即将每个节点的主机名添加到/etc/hosts

10.10.10.1 node1
10.10.10.2 node2
10.10.10.3 node3
10.10.10.4 node4

(3)在主节点下载和设置Ambari repo(可以用更新的Ambari版本号替换"2.4.3.0")

wget -nv http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.4.3.0/ambari.repo -O /etc/yum.repos.d/ambari.repo

(4)检查是否添加成功:

yum repolist | grep ambari
# Updates-ambari-2.4.3.0   ambari-2.4.3.0 - Updates 

(5)制作本地yum源:

    a、首先下载包含必要软件的压缩包(tarball)到本地,以CentOS7,Ambari 2.4.3和HDP 2.5.0.0为例:

Ambari-2.4.3.0 压缩包地址:

http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.4.3.0/ambari-2.4.3.0-centos7.tar.gz

HDP-2.5.0.0压缩包地址:

http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.5.0.0/HDP-2.5.0.0-centos7-rpm.tar.gz

HDP UTILS压缩包下载地址:

http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos7/HDP-UTILS-1.1.0.21-centos7.tar.gz

其他版本,下载地址请参考:

Ambari:

http://docs.hortonworks.com/HDPDocuments/Ambari-2.4.1.0/bk_ambari-installation/content/ambari_repositories.html

HDP和HDP UTILS:

http://docs.hortonworks.com/HDPDocuments/Ambari-2.4.1.0/bk_ambari-installation/content/hdp_stack_repositories.html

b、设置本地库,我们先需要完成一些准备工作,如下:

  1. 选择一台机器作为本地库的镜像服务器,这个机器能够被集群中的机器所访问,且有一个被支持的操作系统。
  2. 此台镜像服务器有软件包管理,例如centOS的yum。

c、在镜像服务器上安装一个HTTP服务(例如Apache httpd)

yum install httpd

     启动web 服务:

[root@master ~]# systemctl start httpd
[root@master ~]# systemctl enable httpd

 d、把下载到的3个资源文件,并解压到http服务(web服务)目录下:

# mkdir /var/www/html/ambari-hdp
# mkdir /var/www/html/ambari-hdp/HDP-UTILS
# tar -xvf ambari-2.4.1.0-centos7.tar.gz -C /var/www/html/ambari-hdp/
# tar -xvf HDP-2.5.0.0-centos7-rpm.tar.gz -C /var/www/html/ambari-hdp/
# tar -xvf HDP-UTILS-1.1.0.21-centos7.tar.gz -C /var/www/html/ambari-hdp/HDP-UTILS

e、 确认解压目录正常,在浏览器中确认是否可以访问,访问地址如下:

Ambari Base URL:http://172.16.16.183:82/ambari-hdp/centos7/

HDP Base URL:http://172.16.16.183:82/ambari-hdp/HDP/centos7/

HDP-UTILS Base URL:http://172.16.16.183:82/ambari-hdp/HDP-UTILS/

f、配置Yum本地Repos资源池(在每台node上)

安装插件:

yum install yum-plugin-priorities

 编辑/etc/yum/pluginconf.d/priorities.conf 文件添加如下配置:

[main]
enabled=1
gpgcheck=0

制作本地资源文件,创建Ambari、HDP、HDP-UTIL资源文件:

  •   ambari.repo
[ambari-2.4.1.0]
name=ambari-2.4.1.0
baseurl=http://192.168.0.203/ambari-hdp/AMBARI-2.4.1.0/centos7/2.4.1.0-22/
gpgcheck=0
gpgkey=http://192.168.0.203/ambari-hdp/AMBARI-2.4.1.0/centos7/2.4.1.0-22/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1
  •   hdp.repo
[HDP-2.5.0.0]
name=Hortonworks Data Platform Version - HDP-2.5.0.0
baseurl=http://192.168.0.203/ambari-hdp/HDP/centos7
gpgcheck=0
gpgkey=http://192.168.0.203/ambari-hdp/HDP/centos7/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1
  •   hdp-util.repo
[HDP-UTILS-1.1.0.21]
name=Hortonworks Data Platform Version - HDP-UTILS-1.1.0.21
baseurl=http://192.168.0.203/ambari-hdp/HDP-UTILS/
gpgcheck=0
gpgkey=http://192.168.0.203/ambari-hdp/HDP-UTILS/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1

   查看资源池:

  [root@master yum.repos.d]# yum repolist 
  repo id                                          repo name                                                                     status
  HDP-2.5                                          HDP-2.5                                                                        0+200
  HDP-2.5.0.0                                      Hortonworks Data Platform Version - HDP-2.5.0.0                                  200
  HDP-UTILS-1.1.0.21                               HDP-UTILS-1.1.0.21                                                                64
  ambari-2.4.1.0                                   ambari-2.4.1.0   

(5)安装和设置Ambari server:

yum install ambari-server -y

安装完成后创建ambari数据库及用户,登录root用户执行下面语句:

mysql> create database ambari character set utf8;
mysql> CREATE USER 'ambari'@'%' IDENTIFIED BY 'ambari';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
mysql> FLUSH PRIVILEGES;

如果要安装Hive,再创建Hive数据库和用户 再执行下面的语句:

mysql> create database hive character set utf8;
mysql> CREATE USER 'hive'@'%' IDENTIFIED BY 'hive';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%';
mysql> FLUSH PRIVILEGES;

如果要安装Oozie,再创建Oozie数据库和用户 再执行下面的语句:

mysql> create database oozie character set utf8;
mysql> CREATE USER 'oozie'@'%' IDENTIFIED BY 'oozie';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'%';
mysql> FLUSH PRIVILEGES; 

(6) 配置Ambari-Server

Press  to continue.

 到上面一步时,提示需要配置mysql的 jdbc驱动,并修改Ambari配置文件,指定jdbc驱动文件位置:

在安装Metron准备(11)步骤时我们安装了JAVA MySQL连接器其默认路径为(/usr/share/java/),所以我们只需要在Ambari配置文件中添加jdbc驱动文件位置即可,即在编辑/etc/ambari-server/conf/ambari.properties添加如下配置:

server.jdbc.driver.path=/usr/share/java/mysql-connector-java.jar

 配置完成后继续,会出现如下提示:

Press  to continue.
Configuring remote database connection properties...
WARNING: Before starting Ambari Server, you must run the following DDL against the database to create the schema: /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql
Proceed with configuring remote database connection properties [y/n] (y)? 

 出现上述提示时,根据信息导入数据库:将Ambari数据库脚本导入到数据库。Ambari安装会将安装等信息写入数据库,建议使用自己安装的MySQL数据库,也可以不安装而使用默认数据库PostgreSQL。如果使用自己定义的数据库,必须在启动Ambari服务之前导入Ambari的sql脚本。

# mysql -uroot -p
mysql> use ambari;
mysql> source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql;

(6)通过运行mpack命令将Metron服务添加到Ambari(确保在--mpack =中指定正确的mpack路径):

ambari-server install-mpack --mpack=/root/metron/metron-deployment/packaging/ambari/metron-mpack/target/metron_mpack-0.4.1.0.tar.gz --verbose

 (7)启动Ambari服务

ambari-server start

(8)服务启动成功后,会监听8080端口,通过在Web浏览器中访问Ambari UI:http://:8080/,账号密码admin/admin正常登录,则安装完成。结果如下图所示(图片来自网络,仅供参考):

安装Metron_第2张图片

(9)创建集群

使用ambari的web界面可完成对集群的所有管理操作,创建一个实例集群。

安装Metron_第3张图片

 选择本地源,移除不必要的版本:

安装Metron_第4张图片

 设置本地源为以上步骤中制作的本地源:

Base URL:ambari :http://172.16.16.183:82/ambari-hdp/ambari/centos7/

                     HDP :http://172.16.16.183:82/ambari-hdp/HDP/centos7/

                    HDP-UTILS:http://172.16.16.183:82/ambari-hdp/HDP-UTILS/

及Metron 源采用本地源:file:localrepo/repodata

添加主机节点,上传(Ambari server 节点的)id_rsa文件:
安装Metron_第5张图片

(9)安装Ambari agent,组建集群,如下图所示(由于在安装过程中不仅需要从本地HDP及Metron配置的源中下载文件还需要联网下载文件所以需要时间较长,且有时会因为网络超时导致安装失败,可能需要多次重试,请周知):

 在安装过程中,ambari注册主机的时候,ambari-agent出现如下错误:

NetUtil.py:96 - EOF occurred in violation of protocol (_ssl.c:579)
NetUtil.py:97 - SSLError: Failed to connect. Please check openssl library versions.

有两种可能:

第一是有可能如前面所提到的使用的是centos7、python 2.7.5及以上版本的python 会在安装Ambari agent时报错:

[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:579)

解决办法是:要解决此问题,即在此处禁用Python中的证书检查


sed -i 's/verify=platform_default/verify=disable/' /etc/python/cert-verification.cfg

第二是Ambari agent安全验证引起的;

解决方案 在ambari-agent的配置文件ambari-agent.ini 在 [security]增加一项

[security] 
force_https_protocol=PROTOCOL_TLSv1_2

2.如出现bootstrap、stack-recommendations 目录找不到的错误:

解决方案:

进入/var/run/ambari-server,手动创建bootstrap文件夹,并对其添加owner为ambari:

chown ambari bootstrap

然后重启Ambari server

ambari-server restart

安装成功后,会显示如下界面:
安装Metron_第6张图片
(9)使用Ambari安装其他组件

        a.首先,输入集群任意集群名称;

        b.选择版本:确保选中"Public Repository"。您还应该看到列出的/localrepo目录。

       c.设置安装选项:在"Target Hosts"中指定安装Ambari集群的节点的主机名(/ etc / hosts中指定的所有节点)。在"Host Registration Information"中复制主节点私钥(/root/.ssh/id_rsa)的内容。如果收到警告"以下主机名无效FQDN",请忽略它并单击"确定"。

       d.选择服务:选择以下服务:

安装Metron_第7张图片  

HDFS
YARN + MapReduce2
Tez
HBase
Pig
Zookeeper
Storm
Flume
Ambari Metrics
Kafka
Elasticsearch
Kibana
Metron
Slider
OpenTAXII
Pycapa
Zeppelin Notebook
Hive

      e.分配Masters:在所有节点上分配"Kafka Broker",确保在一个公共节点上安装以下组件:

Storm UI Server
Metron Indexing
MySQL Server
Kibana Server
Elasticsearch Master
Metron Parsers
Metron Enrichment

      f. 分配Slaves和Clients:

DataNode
NodeManager
RegionServer
Supervisor
Client

      g.自定义服务:以下是需要配置的服务列表:

(1)在HDFS - > Configs下将"NameNode Java堆大小"(namenode_heapsize)从默认的1024 MB设置为至少4096 MB。

(2)对于ElasticSearch:
将"zen_discovery_ping_unicast_hosts"设置为在Assign Master选项卡上分配ElasticSearch Master的节点的IP。
在"Advanced elastic-site"下:将"network_host"更改为"0.0.0.0"。如果Metron暴露在公共互联网上,请不要这样做!现在是“[_local_,_ site_]”。
(3)对于Kibana:
将"kibana_es_url"设置为http:// :9200。elasticsearch_master_hostname是" Assign Master "选项卡上分配ElasticSearch Master的节点的IP。
将"kibana_default_application"更改为"dashboard / Metron-Dashboard"
(4)对于Metron:将"Elasticsearch Hosts"设置为在Assign Master选项卡上分配ElasticSearch Master的节点的IP。
(5)对于Storm:将"supervisor.slots.ports"的数量从默认的[6700,6701]增加到[6700,6701,6702,6703,6704]如果只安装一个节点。
(6)对于metron REST使用:
           Metron JDBC客户端路径:/usr/share/java/mysql-connector-java.jar
           Metron JDBC驱动程序:com.mysql.jdbc.Driver

 配置Metron REST,Metron REST可能无法工作,因为我们仍然需要将用户和数据库添加到MariaDB。此时,请确保所有服务都已启动,需要手动启动一些。

在MySQL中为Metron REST配置用户。在安装Metron REST UI的节点上,执行以下操作:

# mysql -u root -p
CREATE USER ''@'localhost' IDENTIFIED BY '';
CREATE DATABASE IF NOT EXISTS ;
GRANT ALL PRIVILEGES ON .* TO ''@'localhost';

例如:

# mysql -u root -p
> CREATE USER 'metron'@'localhost' IDENTIFIED BY 'metron';
> CREATE DATABASE IF NOT EXISTS metronrest;
> GRANT ALL PRIVILEGES ON metronrest.* TO 'metron'@'localhost';
> quit
Bye
# 

在metron REST服务运行之前,我们需要做最后一步。 由于Centos 7中的systemd,服务metron-rest start 不再有效。因此,必须编辑配置文件"/etc/rc.d/init.d/metron-rest"。 在此文件中,将METRON_JDBC_PASSWORD ="$2"更改为METRON_JDBC_PASSWORD =""并通过Ambari界面重新启动metron-rest服务。

配置以下项时,请确保已启动Metron REST UI。

将Metron REST用户名和密码添加到metronrest数据库:

# mysql -u  -p
> use ;
> insert into users (username, password, enabled) values ('','',1);
> insert into authorities (username, authority) values ('', 'ROLE_USER');
> quit
Bye
#

例如:

# mysql -u metron -p
> use metronrest;
> insert into users (username, password, enabled) values ('metron','metron',1);
> insert into authorities (username, authority) values ('metron', 'ROLE_USER');
> quit
Bye
#

确保所有服务都已启动。
