本篇内容主要讲解“怎么用中间组件配置ELK+logback搭建日志系统”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“怎么用中间组件配置ELK+logback搭建日志系统”吧!
命令执行如下 # adduser es # passwd es123456 用root 给新建用户赋予权限 1、进入bin目录下执行chmod +x elasticsearch 2、chown es.es -R /opt/elasticsearch-5.1.1 3、切换到新建用户 # su es 4、修改vm.map 限制 vi /etc/sysctl.conf vm.max_map_count=262144 5、进入bin目录 执行./elasticsearch -d & 然后就可以在命令行中用curl http://localhost:9200?pretty 看看输出 此时，ES可以在本地访问，但是用浏览器远程的话，还是无法访问的，因为相应的端口没有打开
# ======================== Elasticsearch Configuration ========================= # ---------------------------------- Cluster ----------------------------------- `cluster.name: elk-es` # ------------------------------------ Node ------------------------------------ node.name: node-1 # ----------------------------------- Paths ------------------------------------ path.data: /data/program/elk/es/data path.logs: /data/program/elk/es/logs # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # #bootstrap.memory_lock: true # # ---------------------------------- Network ----------------------------------- network.host: 10.100.0.222 http.port: 9200 # --------------------------------- Discovery ---------------------------------- 接下来重启es 然后通过浏览器外部访问就可以了
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536] 意思是说你的进程不够用了 解决方案： 切到root 用户：进入到security目录下的limits.conf；执行命令 vim /etc/security/limits.conf 在文件的末尾添加下面的参数值： * soft nofile 65536 * hard nofile 131072 * soft nproc 65536 * hard nproc 65536 前面的*符号必须带上，然后重新启动就可以了。执行完成后可以使用命令 ulimit -n 查看进程数 [2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] 需要修改系统变量的最大值了 [3]:解决方案：切换到root用户修改配置sysctl.conf 增加配置值： vm.max_map_count=655360 执行命令 sysctl -p 这样就可以了，然后重新启动ES服务 就可以了
如果没有什么问题话，就可以安全生成了；然后执行curl 'http://自己配置的IP地址:9200/' 命令，就出现下面的结果

}6.1 下载head安装包，下载地址：https://github.com/mobz/elasticsearch-head/archive/master.zip 这是接从git 上下载下来 ，然后上传到虚拟机上的；由于head 插件不能放在elasticsearch-5.6.3 文件夹里，head 插件需要单独放，单独去执行；
所 以在elasticsearch-5.6.3 同级目录下解压了 head 插件；解压出来的文件名字，如图
[root@redis-node1 elk]# wget https://github.com/mobz/elasticsearch-head/archive/master.zip --2018-07-10 11:55:41-- https://github.com/mobz/elasticsearch-head/archive/master.zip Resolving github.com (github.com)... 13.229.188.59, 52.74.223.119, 13.250.177.223 Connecting to github.com (github.com)|13.229.188.59|:443... connected.

6.1.2 elasticsearch-head 解压和安装
[root@redis-node1 es-head]# pwd /data/program/elk [root@redis-node1 elk]# unzip master.zip -d ./ [root@redis-node1 elk]# ll total 904 drwxr-xr-x 6 root root 4096 Sep 15 2017 elasticsearch-head-master drwxr-xr-x 9 elk elk 188 Jul 10 11:42 es drwxrwxr-x 13 elk elk 260 Jul 6 12:47 kibana drwxr-xr-x 12 elk elk 278 Jul 10 10:43 logstash -rw-r--r-- 1 root root 921421 Jul 10 11:55 master.zip [root@redis-node1 elk]# mv elasticsearch-head-master es-head [root@redis-node1 elk]# ll total 904 drwxr-xr-x 9 elk elk 188 Jul 10 11:42 es drwxr-xr-x 6 root root 4096 Sep 15 2017 es-head drwxrwxr-x 13 elk elk 260 Jul 6 12:47 kibana drwxr-xr-x 12 elk elk 278 Jul 10 10:43 logstash -rw-r--r-- 1 root root 921421 Jul 10 11:55 master.zip [root@redis-node1 es-head]# cd es-head [root@redis-node1 es-head]# pwd /data/program/elk/es-head
6.2 执行head 插件，需要node.js 的支持，所以，下面先安装一node.js
6.2.1 执行命令一：curl -sL https://rpm.nodesource.com/setup_8.x | bash -

6.2.2 命令二：yum install -y nodejs

6.2.3 OK，执行完成后，可以使用命令 node -v 验证是否安装成功，同时npm 也安装成功了；执行命令 npm -v 也是可以验证的。
[root@redis-node1 ~]# node -v v8.11.3 [root@redis-node1 ~]# npm -v 5.6.0 [root@redis-node1 ~]#
6.3 安装grunt ,由于head 插件的执行文件是有grunt 命令来执行的，所以这个命令必须安装
6.3.1 安装命令一：npm install grunt --save-dev 命令二：npm install
[root@redis-node1 ~]# npm install grunt --save-dev npm WARN saveError ENOENT: no such file or directory, open '/root/package.json' npm notice created a lockfile as package-lock.json. You should commit this file. npm WARN enoent ENOENT: no such file or directory, open '/root/package.json' npm WARN root No description npm WARN root No repository field. npm WARN root No README data npm WARN root No license field. + grunt@1.0.3 added 96 packages in 32.604s [root@redis-node1 ~]# npm install npm WARN saveError ENOENT: no such file or directory, open '/root/package.json' npm WARN enoent ENOENT: no such file or directory, open '/root/package.json' npm WARN root No description npm WARN root No repository field. npm WARN root No README data npm WARN root No license field. up to date in 0.996s [root@redis-node1 ~]#
6.3.2 修改配置文件，cd 进入elasticsearch-head-master 文件夹下，执行命令vim Gruntfile.js文件：增加hostname属性，设置为*；如图：
connect: {
server: {
options: {
port: 9100,
`hostname:*`
base: '.',
keepalive: true
}
}
}6.3.3 修改 vi _site/app.js 文件：修改head的连接地址:，如图所示：
(function( app, i18n ) {
var ui = app.ns("ui");
var services = app.ns("services");
app.App = ui.AbstractWidget.extend({
defaults: {
base_uri: null
},
init: function(parent) {
this._super();
this.prefs = services.Preferences.instance();
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || **"http://10.100.0.222:9200"**;
if( this.base_uri.charAt( this.base_uri.length - 1 ) !== "/" ) {
// XHR request fails if the URL is not ending with a "/"
this.base_uri += "/";
}6.3.4 最后一个命令： grunt server & 执行完成后就OK了
6.3.5 涉及到的问题，在网页上无法正常访问；查看防火墙是否关闭
6.3.5.1 执行命令service iptables status 查看状态 ；直接将防火墙关闭就好了 执行命令service iptables stop 最后执行的结果是这样的，我没有配置集群： 注意下面使用的端口号，不在是9200 了 而是head 插件中的 9100 了 看到上面的出现的健康值了吗，说明的连接还是有问题的，解决方案是修改 cd 命令进入到elasticsearch-5.6.3 /config 文件中 vi elasticsearch.yml 文件下添加 ：
http.cors.enabled: true http.cors.allow-origin: "*"
6.4 然后重新执行ES ./elasticsearch 成功起来就可以了，执行结果就是这样的
wget https://artifacts.elastic.co/downloads/logstash/logstash-6.3.1.tar.gz tar -xzf logstash-6.3.1.tar.gz mv logstash-6.3.1-linux-x86_64 logstash ch logstash
input {
tcp {
##host:port就是上面appender中的 destination，这里其实把logstash作为服务，开启9601端口接收logback发出的消息

port => 9601
#模式选择为server
mode => "server"

##格式json
codec => json_lines
}
}
output {
elasticsearch {

}

(1)、gc.server.project.name 为项目名称，在application.properties配置；
(2)、gc.server.ip.port 为Logstash 提供的TcpSocket的服务ip和端口

<property resource="application.properties" />
<!--输出到elk的LOGSTASH-->
