ELK5.2+kafka+zookeeper+filebeat集群部署

架构图

  • 考虑到日志系统的可扩展性以及目前的资源（部分功能复用），整个ELK架构如下：

这里写图片描述

架构解读 : （整个架构从左到右，总共分为5层）

第一层、数据采集层

最左边的是业务服务器集群，上面安装了filebeat做日志采集，同时把采集的日志分别发送给两个logstash服务（2.187、2.189）

第二层、数据处理层，数据缓存层

logstash服务把接受到的日志经过格式处理，转存到本地的kafka broker+zookeeper 集群中。

第三层、数据转发层

这个单独的Logstash（2.184）节点会实时去kafka broker集群拉数据，转发至ES DataNode。

第四层、数据持久化存储

ES DataNode 会把收到的数据，写磁盘，建索引库。

第五层、数据检索，数据展示

ES Master + Kibana 主要 协调 ES集群，处理数据检索请求，数据展示。

安装部署

  • 系统优化

    cat /etc/sysctl.conf
    net.ipv4.tcp_max_syn_backlog = 4096
    net.core.netdev_max_backlog = 2048
    net.ipv4.tcp_fin_timeout = 15
    net.ipv4.tcp_tw_reuse = 1
    net.ipv4.tcp_tw_recycle = 1
    net.ipv4.tcp_syncookies = 1
    vm.max_map_count= 262144 #后期配置ES很关键
    vm.swappiness = 1
    cat /etc/security/limits.conf
    *                               soft    nofile  65536
    *                               hard    nofile  65536

  • 配置java环境 

    cd /apps/svr
    tar zxvf jdk-8u151-linux-x64.tar.gz
    ln -s jdk1.8.0_151 jdk
     
    cat >> /etc/profile <<EOF
    export JAVA_HOME=/apps/svr/jdk
    export PATH=$JAVA_HOME/bin:$PATH
    export CLASSPATH=.:\$JAVA_HOME/lib/dt.jar:\$JAVA_HOME/lib/tools.jar
    EOF
     
    source /etc/profile

  • 用户问题 
    为了方便这里所有的应用全部都在apps帐号下 
    useradd apps && echo "Qwer1234" | passwd --stdin apps

  • python升级以及安装supervisor 

     

     

     

    cat update_python.sh
    #!/bin/bash
    #creat by xiaojs
    if [ whoami != 'root' ]
    then
    exit 1
    fi
    if [[ python -c "import platform ;print platform.python_version()" = 2.7.* ]]
    then
    echo 'you need not do everything'
    exit 0
    else
    echo '============================'
    echo '=======start update========'
    fi
    # get the tar
    cd /usr/local/src
    wget http://ops.bubugao-inc.com/python/Python-2.7.8.tgz
    wget http://ops.bubugao-inc.com/python/pyinotify.tar.gz
    wget http://ops.bubugao-inc.com/python/MySQL-python-1.2.4.zip
    ##
    yum -y install git gcc mysql mysql-devel

    tar zxvf Python-2.7.8.tgz
    cd Python-2.7.8
    ./configure --prefix=/usr/local/python2.7.8
    make && make install
    mv /usr/bin/python /usr/bin/python_old
    ln -s /usr/local/python2.7.8/bin/python /usr/bin/
    sed -i 's/python/python_old/1' /usr/bin/yum
    #intall the plugin
    cd ..
    tar zxvf pyinotify.tar.gz
    cd pyinotify
    python setup.py install
    cd ..
    unzip MySQL-python-1.2.4.zip
    cd MySQL-python-1.2.4
    python setup.py install
    ####install supervisor
    cd /usr/local/src
    wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
    wget http://pypi.python.org/packages/source/d/distribute/distribute-0.6.10.tar.gz
    tar xf distribute-0.6.10.tar.gz
    cd distribute-0.6.10
    python setup.py install
    easy_install supervisor
    cd /usr/local/python2.7.8/bin/
    cp supervisord supervisorctl echo_supervisord_conf /usr/bin/
    mkdir /etc/supervisor && cd /etc/supervisor
    wget http://ops.bubugao-inc.com/python/supervisord.conf

  • 安装elasticsearch 
    cd /apps/svr/ 
    tar zxvf elasticsearch-5.2.2.tar.gz 
    ln -s elasticsearch-5.2.2 elasticsearch 
    [root@17161 elasticsearch]# sed -n /^[^#]/p config/elasticsearch.yml

    cluster.name: SuperApp
    node.name: manjinba01
    network.host: 0.0.0.0
    http.port: 9200
    discovery.zen.ping.unicast.hosts: ["192.168.2.184:9300","192.168.2.187:9300","192.168.2.189:9300"]
    discovery.zen.minimum_master_nodes: 1
    bootstrap.system_call_filter: false
    bootstrap.memory_lock: false
    http.cors.enabled: true
    http.cors.allow-origin: "*"

启动elasticsearch

chown -R apps.apps /apps

su - apps

cd /apps/svr/elasticsearch

bin/elasticsearch -d

  • 另外两台类似，后续会安装x-pack，所以以前的head和bigdesk不用安装

  • zookeeper+kafka集群部署 

 

#zookeeper 
cd /apps/svr 
tar zxvf zookeeper-3.4.9.tar.gz 
ln -s zookeeper-3.4.9 zookeeper 
mkdir -p /apps/dbdat/zookeeper

server.2=192.168.2.187:12888:13888 
server.3=192.168.2.189:12888:13888

 

#三台服务器分别赋值 
echo 1 > /apps/dbdat/zookeeper/myid 
echo 2 > /apps/dbdat/zookeeper/myid 
echo 3 > /apps/dbdat/zookeeper/myid

 

#启动并查看状态 
/apps/svr/zookeeper/bin/zkServer.sh start 
/apps/svr/zookeeper/bin/zkServer.sh status 
[root@17163 zookeeper]# /apps/svr/zookeeper/bin/zkServer.sh status 
ZooKeeper JMX enabled by default 
Using config: /apps/svr/zookeeper/bin/../conf/zoo.cfg

#以上信息就是没问题

 

#kafka集群

cd /apps/svr
 tar zxvf kafka_2.10-0.10.2.0.tgz
ln -s kafka_2.10-0.10.2.0 kafka

#不同的节点，注意broker.id和linsten的ip

\#启动查看是否正常
nohup /apps/svr/kafka/bin/kafka-server-start.sh /apps/svr/kafka/config/server.properties &
 
\#有一些用得到的指令
bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test  # 创建topic
 
bin/kafka-topics.sh --list --zookeeper localhost:2181   # 查看已经创建的topic列表
 
bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic test  # 查看topic的详细信息
 
bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test # 发送消息, 回车后模拟输入一下消息
 
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test # 消费消息, 可以换到其他kafka节点, 同步接收生产节点发送的消息
 
bin/kafka-topics.sh --zookeeper localhost:2181 --alter --topic test --partitions 6  # 给topic增加分区
 
bin/kafka-topics.sh --delete --zookeeper localhost:2181 --topic test1  # 删除已经创建的topic, 前提是开了delete.topic.enable=true参数
 
如果还不能删除, 可以到zookeeper中去干掉它
cd /usr/local/zookeeper-3.4.10/
bin/zkCli.sh
ls /brokers/topics            # 查看topic
rm -rf /brokers/topics/test1     # 删除topic

 

logstash的部署和配置 

 
cd /apps/svr 
tar zxvf logstash-5.2.2.tar.gz 
ln -s logstash-5.2.2/ logstash 
#安装都一样，重点是两端配置文件不一样，一个是负责写入kafka，一个是负责从kafka提取出来写入elasticsearch,配置分别如下： 
[root@17162 ~]# cat /apps/conf/logstash/logstash-in-kafka.conf

启动logstash

192.168.2.184

nohup /apps/svr/logstash/bin/logstash -f /apps/conf/logstash/logstash-kafka.conf &

192.168.2.187/192.168.2.189

nohup /apps/svr/logstash/bin/logstash -f /apps/conf/logstash/logstash-in-kafka.conf &

 

应用服务器的filebeat的配置

 

 

cd /apps/svr
tar zxvf filebeat-5.2.2-linux-x86_64.tar.gz
ln -s filebeat-5.2.2-linux-x86_64 filebeat
[root@java1732 svr]# sed -n ‘/^[^#]/’p filebeat/filebeat.yml
filebeat.prospectors:
  
- input_type: log
  paths:
    - /var/log/messages
  document_type: sys-messages
output.logstash:
# The Logstash hosts
 hosts: ["192.168.2.187:5044","192.168.2.189:5044"]
 
#调试指令：./filebeat -e -c filebeat.yml -d “production”
 
启动： nohup ./filebeat -c filebeat.yml -e &

 

kibana页面配置 

cd /apps/svr
tar zxvf kibana-5.2.2-linux-x86_64.tar.gz
ln -s kibana-5.2.2-linux-x86_64 kibana
[root@17161 kibana]# sed -n ‘/^[^#]/’p config/kibana.yml
server.port: 5601
server.host: "192.168.2.189"
elasticsearch.url: "http://192.168.2.189:9200"
kibana.index: ".kibana"

启动kibana

nohup bin/kibana &

 

 

#对应的nginx的配置如下

 

upstream kibana {
        keepalive      400;
           server  192.168.2.184:5601 max_fails=3  fail_timeout=30s;
}
server  {
    listen          80;
    server_name     192.168.2.184;
 
    if (-d $request_filename) {
        rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;
    }
 
    location / {
        proxy_pass              http://kibana;
        proxy_http_version 1.1;
        proxy_set_header Connection "";
        proxy_set_header        X-Real-IP  $remote_addr;
        proxy_set_header        Host             $host;
        proxy_set_header        X-Forwarded-For  $proxy_add_x_forwarded_for;
    }
    error_log           logs/kinaba5.error.log;
    access_log          logs/kinaba5.access.log log_access;

 

}

#至此，整个框架已经完成，可以先建立kafka的topic测试，然后观察elasticsearch的索引是否建立成功，或简单的从页面观察即可

  • 插件和其他相关

    1、由于上述大部分应用都是跑在后台，有时候进程是否挂掉，不得而知，监控如果对于每个进程监控略显麻烦，而且不方便启动，所以这里用supervisor进行统一管理，上述已经有安装记录，具体的配置就不做展示了 
    2、 x-pack的安装 
    /apps/svr/kibana/bin/kibana-plugin install x-pack
