elk6+filebeat+kafka安裝配置

1、安裝elasticsearch
1.)關閉防火牆及SELinux
service iptables stop
chkconfig iptables off
chkconfig iptables --list
vim /etc/sysconfig/selinux
SELinux=disabled
setenforce 0

2.)配置jdk環境
vim /etc/profile.d/java.sh
export JAVA_HOME=/home/admin/jdk1.8.0_172/
export CLASSPATH=.:$JAVA_HOME/lib.tools.jar
export PATH=$JAVA_HOME/bin:$PATH
source /etc/profile.d/java.sh

3.)安裝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
node.name: node-1
network.host: 10.2.151.203
http.port: 9200
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
http.cors.enabled: true
http.cors.allow-origin: "*"

4.)啓動elasticsearch
useradd elk
chown –R elk.elk /home/admin/project/elk/elasticsearch-6.2.4
./bin/elasticsearch –d

netstat –luntp #查看監聽端口9200 9300

curl 10.2.151.203:9200

5.)啓動常見錯誤
uncaught exception in thread [main]
org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run elasticsearch as root
問題原因：不能使用root用戶啓動
解決方法：切換要其他用戶啓動

unable to install syscall filter:
java.lang.UnsupportedOperationException: seccomp unavailable:
問題原因：其實只是一個警告，主要是因爲你Linux版本過低造成的
解決方法：警告不影響使用，可以忽略

ERROR: bootstrap checks failed
memory locking requested for elasticsearch process but memory is not locked
問題原因：鎖定內存失敗
解決方法：切換到root用戶，編輯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：無法創建本地線程問題,用戶最大可創建線程數太小
解決方案：切換到root用戶，進入limits.d目錄下，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：最大虛擬內存太小
解決方案：切換到root用戶下，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
問題原因：因爲Centos6不支持SecComp
解決方法：在elasticsearch.yml中配置bootstrap.system_call_filter爲false，注意要在Memory下面:
bootstrap.memory_lock: false
bootstrap.system_call_filter: false

2、elasticsearch-head插件安裝
通過web界面來查看elasticsearch集羣狀態信息

1.)下載安裝nodejs
wget https://nodejs.org/dist/v8.11.3/node-v8.11.3-linux-x64.tar.xz

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

cd elasticsearch-head-master
npm install
#如果速度較慢或安裝失敗，建議使用國內鏡像
npm install --ignore-scripts -g cnpm --registry=https://registry.npm.taobao.org

4.)修改elasticserach配置文件
vi ./config/elasticsearch.yml
#增加新的參數，這樣head插件可以訪問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

#localhost替換爲IP地址
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://10.2.151.203:9200";

7.) 啓動grunt
grunt server
#如果啓動成功，則可以直接使用後臺運行，命令行可繼續輸入（但是如果想退出，則需要自己kill進程）
grunt server &
nohup grunt server & exit #後臺啓動

#啓動提示模塊未找到

> Local Npm module "grunt-contrib-jasmine" not found. Is it installed?
