ELK6+kafka+filebeat安装配置

1、安装elasticsearch
1.)关闭防火墙及SELinux
service iptables stop
chkconfig iptables off
chkconfig iptables --list
vim /etc/sysconfig/selinux
SELinux=disabled
setenforce 0

2.)配置jdk环境
vim /etc/profile.d/java.sh
export JAVA_HOME=/home/admin/jdk1.8.0_172/
export PATH=$ JAVA_HOME/BIN:$PATH

export CLASSPATH=.:$JAVA_HOME/lib.tools.jar
source /etc/profile.d/java.sh

3.)安装ElasticSearch6.x
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.tar.gz
tar -zxvf elasticsearch-6.2.4.tar.gz -C /home/admin/project/elk
cd /home/admin/project/elkelasticsearch-6.2.4
vim config/elasticsearch.yml
cluster.name: elasticsearch #集群名称
node.name: node-1 #节点名称
network.host: 127.0.0.1
http.port: 9200
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
http.cors.enabled: true
http.cors.allow-origin: “*”

4.)启动elasticsearch
useradd elk
chown –R elk.elk /home/admin/project/elk/elasticsearch-6.2.4
./bin/elasticsearch –d #后台启动

netstat –luntp |grep 9200 #查看监听端口9200

curl 10.2.151.203:9200

5.)启动常见错误
uncaught exception in thread [main]
org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run elasticsearch as root
问题原因：不能使用root用户启动
解决方法：切换要其他用户启动

unable to install syscall filter:
java.lang.UnsupportedOperationException: seccomp unavailable:
问题原因：其实只是一个警告，主要是因为你Linux版本过低造成的
解决方法：警告不影响使用，可以忽略

ERROR: bootstrap checks failed
memory locking requested for elasticsearch process but memory is not locked
问题原因：锁定内存失败
解决方法：切换到root用户，编辑limits.conf配置文件
vim /etc/security/limits.conf

• hard nproc 65536
• soft nproc 65536
• hard nofile 65536
• soft nofile 65536

max number of threads [1024] for user [es] is too low, increase to at least [2048]
原因：无法创建本地线程问题,用户最大可创建线程数太小
解决方案：切换到root用户，进入limits.d目录下，修改90-nproc.conf 配置文件
vim /etc/security/limits.d/90-nproc.conf

• soft nofile 65536
• soft nproc 65536
• soft nproc 2048

max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
原因：最大虚拟内存太小
解决方案：切换到root用户下，修改配置文件sysctl.conf
vim /etc/sysctl.conf
vm.max_map_count=655360
sysctl -p

system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
问题原因：因为Centos6不支持SecComp
解决方法：在elasticsearch.yml中配置bootstrap.system_call_filter为false，注意要在Memory下面:
bootstrap.memory_lock: false
bootstrap.system_call_filter: false

2、elasticsearch-head插件安装
目的通过web界面来查看elasticsearch集群状态信息

1.)下载安装nodejs
wget https://nodejs.org/dist/v8.11.3/node-v8.11.3-linux-x64.tar.xz
tar -zxvf node-v8.11.3-linux-x64.tar.gz -C /home/admin/project/elk/
cd /home/admin/project/elk/
mv node-v8.11.3-linux-x64/ node-v8.11.3

#配置nodejs环境变量
vim /etc/profile.d/node.sh
export NODE_HOME=/home/admin/project/elk/node-v8.11.3
export PATH=$ NODE_HOME/bin:$PATH

export NODE_PATH=$NODE_HOME/lib/node_modules
source /etc/profile.d/node.sh

#查看nodejs是否生效
[admin@localhost node-v8.11.3]$ node -v
v8.11.3
[admin@localhost node-v8.11.3]$ npm -v
5.6.0

2.)安装grunt
npm config set registry https://registry.npm.taobao.org
vim ~/.npmrc
registry=https://registry.npm.taobao.org
strict-ssl = false
npm install -g grunt-cli
#将grunt加入系统文件
ln -s /home/admin/project/elk/node-v8.11.3/lib/node_modules/grunt-cli/bin/grunt /usr/bin/grunt

3.)下载head二进制包
wget https://codeload.github.com/mobz/elasticsearch-head/zip/master
unzip elasticsearch-head-master.zip
cd elasticsearch-head-master
npm install
#如果速度较慢或安装失败，建议使用国内镜像
npm install --ignore-scripts -g cnpm --registry=https://registry.npm.taobao.org

4.)修改elasticserach配置文件
vi ./config/elasticsearch.yml
增加新的参数，这样head插件可以访问es
http.cors.enabled: true
http.cors.allow-origin: “*”

5.)修改Gruntfile.js配置
vim Gruntfile.js
port: 9100上面增加hostname地址
hostname: “0.0.0.0”,

6.)修改_site/app.js配置
vim _site/app.js
#localhost替换为IP地址
this.base_uri = this.config.base_uri || this.prefs.get(“app-base_uri”) || “http://localhost:9200”;

7.) 启动grunt
grunt server
#如果启动成功，则可以直接使用后台运行，命令行可继续输入（但是如果想退出，则需要自己kill进程）
grunt server &
nohup grunt server & exit #后台启动

#启动提示模块未找到

Local Npm module “grunt-contrib-jasmine” not found. Is it installed?
npm install grunt-contrib-jasmine #安装模块

3、安装kibana

cd /ho me/admin/project/elk/ kibana-6.2.4-linux-x86_64

2.)修改配置
vim config/kibana.yml
server.port: 5601
server.host: “IP"
elasticsearch.url: http://IP:9200

3.)启动kibana
nohup ./bin/kibana &

4、安装logstash

2.)新建模板
vim config/test.conf
input
{
kafka
{
bootstrap_servers => “10.7.1.112:9092”
topics => “nethospital_2”
codec => “json”
}
}

output
{
if [fields][tag] == “nethospital_2”
{
elasticsearch
{
