ELK5.0安装教程

ELK升级后，安装稍微发生了点变化，在Elasticsearch中增加了很多资源上的限制，其他的倒是没什么变化。不过所有的安装都是基于JDK已经安装完的情况，且为1.8版本。

安装Elasticsearch

在官网下载elsaticsearch安装包：

下载地址

下载对应版本拷贝到服务器，然后执行下面命令解压缩:

tar -zxvf elasticsearch-5.2.2.tar.gz

解压后进入对应的目录,修改配置文件：

cluster.name: page-cluster
node.name: node-104
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
network.host: 0.0.0.0
http.port: 9200
discovery.zen.ping.unicast.hosts: ["other ip"]

其中bootstrap相关是为了解决一个报错：

ERROR: bootstrap checks failed
system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

修改参数vi /etc/sysctl.conf

fs.file-max=65536
vm.max_map_count=262144

然后执行命令sysctl -p

修改系统参数vi /etc/security/limits.conf:

*               soft    nofile          65536
*               hard    nofile          65536
*               soft    nproc           65536
*               hard    nproc           65536

修改参数vi /etc/security/limits.d/90-nproc.conf

* soft nproc 1024
#修改为
* soft nproc 2048

然后进入bin目录，切换新账户执行ulimit -u 2048，执行./elasticsearch

看到下面输出信息：

},

}

安装Kibana

去官网下载Kibana安装包，下载地址

解压缩后，修改配置文件vi kibana.yml：

server.host: 0.0.0.0

运行./bin/kibana,看到输出:

[hdfs@localnode4 bin]$ ./kibana
  log   [05:22:04.137] [info][status][plugin:kibana@5.2.2] Status changed from uninitialized to green - Ready

然后访问对应的页面即可：1.1.1.1:5601

安装logstash

Logstash我用的wondows版本，下载后解压就可以用。下载地址

在logstash_home/bin目录下创建logstash.conf文件，内容如下：

input {
	stdin{}
}
output {
	stdout{codec=>rubydebug}
}

然后执行下面的命令logstash.bat -f logstash.conf:

C:\Users\xx\Documents\workspace\elk\logstash-5.2.2\bin>logstash.bat -f logstash.conf
Could not find log4j2 configuration at path /Users/xinghailong/Documents/workspace/elk/logstash-5.2.2/config/log4j2.properties. Using default config which logs to console
