一、资源规划

服务名所在服务器kafka1—2.13-2.4.1192.168.76.10kafka2—2.13-2.4.1192.168.76.11kafka3—2.13-2.4.1192.168.76.12zookeeper1—3.6.3192.168.76.10zookeeper2—3.6.3192.168.76.11zookeeper3—3.6.3192.168.76.12elasticsearch1—7.12.1192.168.76.10elasticsearch2—7.12.1192.168.76.11elasticsearch3—7.12.1192.168.76.12kibana—7.12.1192.168.76.13logstash—7.12.1192.168.76.14JDK—11.0.21------

二、JDK-11

# 官网下载JDK11的安装包,并上传到服务器解压/home/javatar-zxvf jdk-11.0.21_linux-x64_bin.tar.gz

# 编辑文件并加入以下内容vim /etc.profile
# JAVA_11exportPATH=/home/java/jdk-11.0.21/bin:$PATH# 使环境变量生效source /etc/profile

java-versionjava version "11.0.21"2023-10-17 LTS
Java(TM) SE Runtime Environment 18.9(build 11.0.21+9-LTS-193)
Java HotSpot(TM)64-Bit Server VM 18.9(build 11.0.21+9-LTS-193, mixed mode)

三、kafka

# 以下操作在3个节点执行# zookeeper集群mkdir /apps
cd /apps

wget https://downloads.apache.org/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz

# 三个zookeeper节点执行:解压安装包并做软链接tar xvf apache-zookeeper-3.6.3-bin.tar.gz
ln-sv /apps/apache-zookeeper-3.6.3-bin /apps/zookeeper

# zookeeper配置cd /apps/zookeeper/conf
cp zoo_sample.cfg zoo.cfg
vim zoo.cfg

tickTime=2000initLimit=10syncLimit=5dataDir=/data/zookeeper
clientPort=2181server.1=192.168.76.10:2888:3888
server.2=192.168.76.11:2888:3888
server.3=192.168.76.12:2888:3888

# 创建数据目录mkdir-p /data/zookeeper

# 配置zookeeper节点id(注意,zookeeper集群每个节点的id都不一样)
在zookeeper1节点192.168.76.10上执行:
echo1> /data/zookeeper/myid
在zookeeper2节点192.168.76.11上执行:
echo2> /data/zookeeper/myid
在zookeeper3节点192.168.76.12上执行:
echo3> /data/zookeeper/myid

# 运行zookeeper集群.# 注意:zookeeper配置的初始化时间为10*2000ms,即20s,因此三个节点服务拉起时间不能超过20s,超过20s将会集群初始化失败查看集群各节点角色
/apps/zookeeper/bin/zkServer.sh start

四、elasticsearch

# 以下操作在3个节点执行cd /apps
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.12.1-x86_64.rpm
rpm-ivh elasticsearch-7.12.1-x86_64.rpm

五、kibana

# 下载wget https://artifacts.elastic.co/downloads/kibana/kibana-7.12.1-x86_64.rpm
rpm-ivh kibana-7.12.1-x86_64.rpm

vim /etc/kibana/kibana.yml
server.port: 5601#kibana监听端口

访问:http://192.168.76.13:5601/

六、logstash

# 构建镜像vim logstash.yml
http.host: "0.0.0.0"#xpack.monitoring.elasticsearch.hosts: [ "http://elasticsearch:9200" ]    #关闭xpack功能,该功能收费,如果不关闭将无法正常使用logstash# 准备logstash日志收集的配置,通过配置input日志输入和output输出来匹配收集的容器日志vim app1.conf

宿主机安装logstash消费kafka集群日志

wget https://artifacts.elastic.co/downloads/logstash/logstash-7.12.1-x86_64.rpm
rpm-ivh logstash-7.12.1-x86_64.rpm

# 编辑配置文件vim /etc/logstash/conf.d/daemonset-log-to-es.conf
input {
  kafka {
    bootstrap_servers =>"192.168.76.10:9092,192.168.76.11:9092,192.168.76.12:9092"# kafka三个节点地址
    topics =>["jsonfile-log-topic"]
    codec =>"json"}}

output {if[type]=="jsonfile-daemonset-applog"{
    elasticsearch {
      hosts =>["192.168.76.10:9200","192.168.76.11:9200"]# es地址,写两个就好
      index =>"jsonfile-daemonset-applog-%{+YYYY.MM.dd}"}}if[type]=="jsonfile-daemonset-syslog"{
    elasticsearch {
      hosts =>["192.168.76.10:9200","192.168.76.11:9200"]# es地址,写两个就好
      index =>"jsonfile-daemonset-syslog-%{+YYYY.MM.dd}"}}}# 启动查看有无报错
systemctl start logstash

配置参数说明:
input配置:指定kafka集群个节点地址,指定topics,该topics就是在k8s集群中daemonset yml文件中引用的topics变量,指定编码为json
output配置:通过type过来日志,将过滤的日志发送给elasticsearch,hosts指定elasticsearch集群各节点地址,index指定索引,用日期进行区分。这里分别过滤容器日志jsonfile-daemonset-applog和系统日志jsonfile-daemonset-syslog
hosts:指定elasticsearch集群各节点地址
index:指定索引格式

七、配置kibana
