Wauzh学习笔记（三、Wazuh集群环境搭建）

日常运维疑难杂症 jus4fun 2505 阅读

1.Wazuh分布式部署架构

由于Wazuh中的日志分析匹配工作都是放在Manager节点中进行的，所以单台Manager节点所能支撑的agent数量是有限的。同样的，日积月累数据库中日志数量可能爆炸增长，导致查询速度缓慢。贴心的Wazuh支持部署成集群形式，通过增加集群中节点的数量整个系统将可以支持更多的agent。集群环境的整体架构如下图所示：

2.Wazuh集群安装

以下简单记录Wazuh集群的安装配置过程。

2.1 Elasticsearch数据库集群安装

集群中存在多个Elasticsearch节点，首个节点安装时需要生成证书用于保障通信安全，因此安装步骤与其余节点略有不同。

2.1.1 首个Elasticsearch节点安装

1.安装必要软件包

apt update
apt install curl apt-transport-https unzip wget software-properties-common

2.添加jdk源

add-apt-repository ppa:openjdk-r/ppa

3.安装jdk

apt update
export JAVA_HOME=/usr/ && apt install openjdk-11-jdk

4.添加Wazuh源

curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | apt-key add -
echo "deb https://packages.wazuh.com/4.x/apt/ stable main" | tee -a /etc/apt/sources.list.d/wazuh.list
apt-get update

5.安装elasticsearch及opendistroforelasticsearch 

apt install elasticsearch-oss opendistroforelasticsearch

6.修改elasticsearch数据库配置文件/etc/elasticsearch/elasticsearch.yml。节点数量和信息要和配置文件内容匹配。这里我一共两个elasticsearch节点,分别为:

  • node-1：172.16.0.235
  • node-2： 172.16.0.238

参考写入配置文件如下：

network.host: 0.0.0.0
node.name: node-1
cluster.name: elastic-cluster
cluster.initial_master_nodes:
        - node-1
        - node-2
discovery.seed_hosts:
        - 172.16.0.235
        - 172.16.0.238

node.master: true
node.data: true
node.ingest: true

8.删除默认的证书

rm /etc/elasticsearch/esnode-key.pem /etc/elasticsearch/esnode.pem /etc/elasticsearch/kirk-key.pem /etc/elasticsearch/kirk.pem /etc/elasticsearch/root-ca.pem -f

9.建立证书文件夹

mkdir /etc/elasticsearch/certs
cd /etc/elasticsearch/certs

10.下载tlstool

curl -so ~/search-guard-tlstool-1.8.zip https://maven.search-guard.com/search-guard-tlstool/1.8/search-guard-tlstool-1.8.zip

11.解压tlstool

unzip ~/search-guard-tlstool-1.8.zip -d ~/searchguard

12.修改~/searchguard/search-guard.yml。根据elasticsearch及filebeat(wazuh-manager）的node数量修改配置文件。

# Self-signed certificate authority
ca:
   root:
      dn: CN=elasticsearch,OU=Docu,O=Jus4fun,L=Shanxi,C=CN
      keysize: 2048
      validityDays: 3650
      pkPassword: none
      file: root-ca.pem

# Default values and global settings
defaults:
      validityDays: 3650
      pkPassword: none
      generatedPasswordLength: 12
      httpsEnabled: true

# Nodes certificates
nodes:
  - name: node-1
    dn: CN=node-1,OU=Docu,O=Jus4fun,L=Shanxi,C=CN
    ip: 
      - 172.16.0.235
  - name: node-2
    dn: CN=node-2,OU=Docu,O=Jus4fun,L=Shanxi,C=CN
    ip: 
      - 172.16.0.238
  - name: kibana
    dn: CN=kibana,OU=Docu,O=Jus4fun,L=Shanxi,C=CN 
    ip:
      - 172.16.0.237           

# Clients certificates
clients:
  - name: admin
    dn: CN=admin,OU=Docu,O=Jus4fun,L=Shanxi,C=CN
    admin: true
  - name: filebeat-1
    dn: CN=filebeat-1,OU=Docu,O=Jus4fun,L=Shanxi,C=CN
  - name: filebeat-2
    dn: CN=filebeat-2,OU=Docu,O=Jus4fun,L=Shanxi,C=CN

13.生成证书及密钥并放置在elasticsearch的证书目录下

~/searchguard/tools/sgtlstool.sh -c ~/searchguard/search-guard.yml -ca -crt -t /etc/elasticsearch/certs/
mv /etc/elasticsearch/certs/node-1.pem /etc/elasticsearch/certs/elasticsearch.pem
mv /etc/elasticsearch/certs/node-1.key /etc/elasticsearch/certs/elasticsearch.key
mv /etc/elasticsearch/certs/node-1_http.pem /etc/elasticsearch/certs/elasticsearch_http.pem
mv /etc/elasticsearch/certs/node-1_http.key /etc/elasticsearch/certs/elasticsearch_http.key

14.压缩证书文件并拷贝至集群中其余所有节点（包括wazuh-manager和kibana）

tar -cf /etc/elasticsearch/certs/certs.tar *
拷贝至其余节点，这里我都拷贝到了/home/ubuntu/目录下

15.删除无用文件

rm /etc/elasticsearch/certs/client-certificates.readme /etc/elasticsearch/certs/elasticsearch_elasticsearch_config_snippet.yml search-guard-tlstool-1.7.zip filebeat* node-* -f

16.卸载无用插件

/usr/share/elasticsearch/bin/elasticsearch-plugin remove opendistro_performance_analyzer

17.重启elasticsearch使配置生效

systemctl daemon-reload
systemctl enable elasticsearch
systemctl start elasticsearch

2.1.2 其余Elasticsearch节点安装

1.安装必要软件

apt install curl apt-transport-https unzip wget software-properties-common

2.添加jdk源

add-apt-repository ppa:openjdk-r/ppa

3.安装jdk

apt update
export JAVA_HOME=/usr/ && apt install openjdk-11-jdk

4.添加Wazuh源

curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | apt-key add -
echo "deb https://packages.wazuh.com/4.x/apt/ stable main" | tee -a /etc/apt/sources.list.d/wazuh.list
apt-get update

5.安装elasticsearch和opendistroforelasticsearch

apt install elasticsearch-oss opendistroforelasticsearch

6.修改es数据库配置文件/etc/elasticsearch/elasticsearch.yml。这里我只有两个节点，如下为node-2节点的配置文件。

network.host: 0.0.0.0
node.name: node-2
cluster.name: elastic-cluster
cluster.initial_master_nodes:
        - node-1
        - node-2
discovery.seed_hosts:
        - 172.16.0.235
        - 172.16.0.238

node.master: true
node.data: true
node.ingest: true

opendistro_security.ssl.transport.pemcert_filepath: /etc/elasticsearch/certs/elasticsearch.pem
opendistro_security.ssl.transport.pemkey_filepath: /etc/elasticsearch/certs/elasticsearch.key
opendistro_security.ssl.transport.pemtrustedcas_filepath: /etc/elasticsearch/certs/root-ca.pem
opendistro_security.ssl.transport.enforce_hostname_verification: false
opendistro_security.ssl.transport.resolve_hostname: false
opendistro_security.ssl.http.enabled: true
opendistro_security.ssl.http.pemcert_filepath: /etc/elasticsearch/certs/elasticsearch_http.pem

opendistro_security.nodes_dn:
- CN=node-1,OU=Docu,O=Jus4fun,L=Shanxi,C=CN
- CN=node-2,OU=Docu,O=Jus4fun,L=Shanxi,C=CN
opendistro_security.authcz.admin_dn:
- CN=admin,OU=Docu,O=Jus4fun,L=Shanxi,C=CN


opendistro_security.audit.type: internal_elasticsearch
opendistro_security.enable_snapshot_restore_privilege: true
opendistro_security.check_snapshot_restore_write_privileges: true
opendistro_security.restapi.roles_enabled: ["all_access", "security_rest_api_access"]
cluster.routing.allocation.disk.threshold_enabled: false
node.max_local_storage_nodes: 3

path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch

7.部署证书及密钥文件。其中node-X中的X替换为当前节点的编号。

mkdir /etc/elasticsearch/certs
mv /home/ubuntu/certs.tar /etc/elasticsearch/certs/
cd /etc/elasticsearch/certs/
tar -xf certs.tar node-X.pem node-X.key node-X_http.pem node-X_http.key root-ca.pem
mv /etc/elasticsearch/certs/node-X.pem /etc/elasticsearch/certs/elasticsearch.pem
mv /etc/elasticsearch/certs/node-X.key /etc/elasticsearch/certs/elasticsearch.key
mv /etc/elasticsearch/certs/node-X_http.pem /etc/elasticsearch/certs/elasticsearch_http.pem
mv /etc/elasticsearch/certs/node-X_http.key /etc/elasticsearch/certs/elasticsearch_http.key

8.删除无用文件

rm /etc/elasticsearch/certs/client-certificates.readme /etc/elasticsearch/certs/elasticsearch_elasticsearch_config_snippet.yml search-guard-tlstool-1.7.zip filebeat* node-* -f

9.卸载无用插件

/usr/share/elasticsearch/bin/elasticsearch-plugin remove opendistro_performance_analyzer

10.重启服务

systemctl daemon-reload
systemctl enable elasticsearch
systemctl start elasticsearch

2.1.3 初始化集群

在第一个安装的es数据库节点上执行如下命令进行初始化：

/usr/share/elasticsearch/plugins/opendistro_security/tools/securityadmin.sh -cd /usr/share/elasticsearch/plugins/opendistro_security/securityconfig/ -icl -nhnv -cacert /etc/elasticsearch/certs/root-ca.pem -cert /etc/elasticsearch/certs/admin.pem -key /etc/elasticsearch/certs/admin.key -h <elasticsearch_IP>

其中<elasticsearch_IP>替换为第一个安装的es数据库节点的ip地址。

完成上述初始化后即可使用如下命令测试安装是否成功，若安装成功则显示如下图所示内容：

curl -XGET https://localhost:9200/_cat/nodes -u admin:admin -k

2.2 Wazuh-Manger集群安装

Wazuh-Manger集群中需要有一个控制节点即Master节点，其余的被成为Worker节点。二者仅配置文件略有不同。以下为Master节点和Worker节点均需要进行的安装过程。

1.安装必要软件

apt update
apt install curl apt-transport-https lsb-release gnupg2

2.添加wazuh源

curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | apt-key add -
echo "deb https://packages.wazuh.com/4.x/apt/ stable main" | tee -a /etc/apt/sources.list.d/wazuh.list
apt-get update

3.安装wazuh-manager

apt-get install wazuh-manager

2.2.1 Master节点配置文件修改

修改配置文件/var/ossec/etc/ossec.conf中的<cluster>节。Master节点的参考如下：

  <cluster>
    <name>Jus4fun</name>
    <node_name>masterNode</node_name>
    <node_type>master</node_type>
    <key>c37cd4b580c3e51cab31f5cbbf0ea6f0</key>
    <port>1516</port>
    <bind_addr>0.0.0.0</bind_addr>
    <nodes>
        <node>172.16.0.244</node>
    </nodes>
    <hidden>no</hidden>
    <disabled>no</disabled>
  </cluster>

其中node中填写的ip为Master节点的ip，key值可以使用如下命令生成，需要注意其余节点的key值必须相同：

openssl rand -hex 16

配置修改后需要重启服务

systemctl daemon-reload
systemctl enable wazuh-manager
systemctl start wazuh-manager

2.2.2 Worker节点配置文件修改

修改配置文件/var/ossec/etc/ossec.conf中的<cluster>节。Worker节点的参考如下：

  <cluster>
    <name>Jus4fun</name>
    <node_name>workerNode01</node_name>
    <node_type>worker</node_type>
    <key>c37cd4b580c3e51cab31f5cbbf0ea6f0</key>
    <port>1516</port>
    <bind_addr>0.0.0.0</bind_addr>
    <nodes>
        <node>172.16.0.244</node>
    </nodes>
    <hidden>no</hidden>
    <disabled>no</disabled>
  </cluster>

注意，这里的node里，依旧填写master节点的ip。修改后重启服务：

systemctl daemon-reload
systemctl enable wazuh-manager
systemctl start wazuh-manager

2.2.3 安装filebeat

此处master节点和worker节点安装过程相同。

1.安装filebeat

apt-get install filebeat

2.修改filebeat配置文件/etc/filebeat/filebeat.yml，写入如下内容。注意，hosts里面填入所有es数据库节点的地址。

# Wazuh - Filebeat configuration file
output.elasticsearch:
  hosts: ["172.16.0.235:9200", "172.16.0.238:9200"]
  protocol: https
  username: "admin"
  password: "admin"
  ssl.certificate_authorities:
    - /etc/filebeat/certs/root-ca.pem
  ssl.certificate: "/etc/filebeat/certs/filebeat.pem"
  ssl.key: "/etc/filebeat/certs/filebeat.key"
setup.template.json.enabled: true
setup.template.json.path: '/etc/filebeat/wazuh-template.json'
setup.template.json.name: 'wazuh'
setup.ilm.overwrite: true
setup.ilm.enabled: false

filebeat.modules:
  - module: wazuh
    alerts:
      enabled: true
    archives:
      enabled: false

3.添加es数据库alerts模版文件/etc/filebeat/wazuh-template.json。注意,raw.githubusercontent.com可能被防火墙墙。

curl -so /etc/filebeat/wazuh-template.json https://raw.githubusercontent.com/wazuh/wazuh/4.1/extensions/elasticsearch/7.x/wazuh-template.json
chmod go+r /etc/filebeat/wazuh-template.json

4.安装filebeat的wazuh插件

curl -s https://packages.wazuh.com/4.x/filebeat/wazuh-filebeat-0.1.tar.gz | tar -xvz -C /usr/share/filebeat/module

5.配置filebeat证书，其中filebeat-X中的X替换为对应节点编号。

mkdir /etc/filebeat/certs
mv /home/ubuntu/certs.tar /etc/filebeat/certs/
cd /etc/filebeat/certs/
tar -xf certs.tar filebeat-X.pem filebeat-X.key root-ca.pem
mv /etc/filebeat/certs/filebeat-X.pem /etc/filebeat/certs/filebeat.pem
mv /etc/filebeat/certs/filebeat-X.key /etc/filebeat/certs/filebeat.key

6.重启服务

systemctl daemon-reload
systemctl enable filebeat
systemctl start filebeat

2.2.4 验证安装

1.首先需要验证各节点是否成功加入集群。可以在任意节点执行如下命令检测。

/var/ossec/bin/cluster_control -l

2.验证filebeat和es数据库的连接情况，在任意节点执行以下命令。应能看的所有es数据库的响应输出。

filebeat test output

2.3 Nginx负载均衡安装

1.安装nginx

apt update
apt install nginx

2.添加负载均衡配置，修改/etc/nginx/nginx.conf，添加如下内容：

stream {
    upstream cluster {
        hash $remote_addr consistent;
        server 172.16.0.244:1514;
        server 172.16.0.234:1514;
    }
    upstream master {
        server 172.16.0.244:1515;
    }
    server {
        listen 1514;
        proxy_pass cluster;
    }
    server {
        listen 1515;
        proxy_pass master;
    }
}

其中upstream master中填入wazuh-Manager的master节点的ip。cluster里面填入所有节点的地址。

2.4 Kibana安装

1.安装依赖软件

apt install curl apt-transport-https libcap2-bin

2.添加wazuh源

curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | apt-key add -
echo "deb https://packages.wazuh.com/4.x/apt/ stable main" | tee -a /etc/apt/sources.list.d/wazuh.list
apt-get update

3.安装kibana

apt-get install opendistroforelasticsearch-kibana

4.修改kibana配置文件/etc/kibana/kibana.yml。这里es的hosts有几个就填几个。

server.host: 0.0.0.0
elasticsearch.hosts: ["https://172.16.0.235:9200", "https://172.16.0.238:9200"]
server.port: 443
elasticsearch.ssl.verificationMode: certificate
elasticsearch.username: kibanaserver
elasticsearch.password: kibanaserver
elasticsearch.requestHeadersWhitelist: ["securitytenant","Authorization"]
opendistro_security.multitenancy.enabled: false
opendistro_security.readonly_mode.roles: ["kibana_read_only"]
server.ssl.enabled: true
server.ssl.key: "/etc/kibana/certs/kibana.key"
server.ssl.certificate: "/etc/kibana/certs/kibana.pem"
elasticsearch.ssl.certificateAuthorities: ["/etc/kibana/certs/root-ca.pem"]
server.defaultRoute: /app/wazuh

5.创建kibana数据文件夹

mkdir /usr/share/kibana/data
chown -R kibana:kibana /usr/share/kibana/data

6.将编译好的Wazuh Kibana插件拷贝至/usr/share/kibana，这里插件代码我的放在了/home/ubuntu目录下

apt install unzip
unzip /home/ubuntu/wazuh-kibana-app.zip
mv /home/ubuntu/kibana/wazuh/ /usr/share/kibana/plugins/

7.启动一下服务生成插件的配置文件

systemctl daemon-reload
systemctl enable kibana
systemctl start kibana

8.添加证书，证书为安装第一个es节点的时候生成的。这里我放到了/home/ubuntu目录下

mkdir /etc/kibana/certs
mv /home/ubuntu/certs.tar /etc/kibana/certs/
cd /etc/kibana/certs/
tar -xf certs.tar kibana_http.pem kibana_http.key root-ca.pem
mv /etc/kibana/certs/kibana_http.key /etc/kibana/certs/kibana.key
mv /etc/kibana/certs/kibana_http.pem /etc/kibana/certs/kibana.pem
rm -f certs.tar

9.修改kibana-wazuh插件配置文件，连接wazuh-cluster-master的api。配置文件位于/usr/share/kibana/data/wazuh/config/wazuh.yml。修改url地址为wazuh-cluster-master的api地址。

hosts:
  - default:
     url: https://172.16.0.244
     port: 55000
     username: wazuh-wui
     password: wazuh-wui
     run_as: false

10.给kibana开启443端口的权限

setcap 'cap_net_bind_service=+ep' /usr/share/kibana/node/bin/node

11.重启服务

systemctl restart kibana
