分布式日志平台--ELKStack实践
在运维系统中，经常遇到如下情况:
①开发人员不能登录线上服务器查看详细日志
②各个系统都有日志，日志数据分散难以查找
③日志数据量大，查询速度慢，或者数据不够实时
④一个调用会涉及多个系统，难以在这些系统的日志中快速定位数据
我们可以采用目前比较流行的ELKStack来满足以上需求。
ELK Stack组成部分:
原理流程图如下:
系统环境:
[root@node01 ~]# cat /etc/redhat-release CentOS release 6.4 (Final)[root@node01 ~]# uname -aLinux node01 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux[root@node01 ~]#
| IP地址 | 运行程序 | 角色 | 备注 |
| 10.0.0.41 | elasticsearch | node01 | |
| 10.0.0.42 | elasticsearch | node02 | |
| 10.0.0.43 | elasticsearch | node03 | |
| 10.0.0.44 | redis kibana | kibana | |
| 10.0.0.9 | nginx logstash | web01 | |
| 10.0.0.10 | logstash | logstash |
实战操作:
①下载安装包安装Java环境以及配置环境变量:
[root@node01 tools]# ll
total 289196
-rw-r--r-- 1 root root 28487351 Mar 24 11:29 elasticsearch-1.7.5.tar.gz
-rw-r--r-- 1 root root 173271626 Mar 24 11:19 jdk-8u45-linux-x64.tar.gz
-rw-r--r-- 1 root root 18560531 Mar 24 11:00 kibana-4.1.6-linux-x64.tar.gz
-rw-r--r-- 1 root root 74433726 Mar 24 11:06 logstash-2.1.3.tar.gz
-rw-r--r-- 1 root root 1375200 Mar 24 11:03 redis-3.0.7.tar.gz
[root@node01 tools]#
安装jdk(在本次实验中所有服务器上做同样的操作安装jdk,这里以node01为例):
[root@node01 tools]# tar xf jdk-8u45-linux-x64.tar.gz
[root@node01 tools]# ll
[root@node01 tools]# mv jdk1.8.0_45 /usr/java/
[root@node01 tools]# vim /etc/profile
export JAVA_HOME=/usr/java/jdk1.8.0_45
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
[root@node01 ~]#
[root@node01 ~]# source /etc/profile
[root@node01 ~]# java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
[root@node01 ~]#
②安装配置elasticsearch（node01、node02、node03上做同样操作）
[root@node01 tools]# tar xf elasticsearch-1.7.5.tar.gz
[root@node01 tools]# mv elasticsearch-1.7.5 /usr/local/elasticsearch
[root@node01 tools]#
[root@node01 tools]# cd /usr/local/elasticsearch/
[root@node01 elasticsearch]# ll

-rw-rw-r-- 1 root root 150 Feb 2 17:24 NOTICE.txt
-rw-rw-r-- 1 root root 8700 Feb 2 17:24 README.textile
[root@node01 elasticsearch]#
[root@node01 elasticsearch]# cd config/
[root@node01 config]# ll
total 20
-rw-rw-r-- 1 root root 13476 Feb 2 17:24 elasticsearch.yml
-rw-rw-r-- 1 root root 2054 Feb 2 17:24 logging.yml
[root@node01 config]#
修改配置文件如下:
[root@node01 config]#
[root@node01 config]# grep -vE '^#|^$' elasticsearch.yml
cluster.name: elasticsearch
node.name: "node01"
node.master: true
node.data: true
index.number_of_shards: 5
index.number_of_replicas: 1
path.conf: /usr/local/elasticsearch/config
path.data: /usr/local/elasticsearch/data
path.work: /usr/local/elasticsearch/work
path.logs: /usr/local/elasticsearch/logs
path.plugins: /usr/local/elasticsearch/plugins
bootstrap.mlockall: true
[root@node01 config]#
创建对应的目录:
[root@node01 elasticsearch]# mkdir -p /usr/local/elasticsearch/{data,work,logs,plugins}
[root@node01 elasticsearch]# ll
total 56
drwxr-xr-x 2 root root 4096 Mar 24 11:34 bin
drwxr-xr-x 2 root root 4096 Mar 24 12:52 config

drwxr-xr-x 3 root root 4096 Mar 24 11:34 lib
-rw-rw-r-- 1 root root 11358 Feb 2 17:24 LICENSE.txt
drwxr-xr-x 2 root root 4096 Mar 24 13:00 logs
-rw-rw-r-- 1 root root 150 Feb 2 17:24 NOTICE.txt
drwxr-xr-x 2 root root 4096 Mar 24 13:01 plugins
-rw-rw-r-- 1 root root 8700 Feb 2 17:24 README.textile
drwxr-xr-x 2 root root 4096 Mar 24 13:00 work
[root@node01 elasticsearch]#
③启动elasticsearch服务
[root@node01 elasticsearch]# pwd
/usr/local/elasticsearch
[root@node01 elasticsearch]# ll
total 44
drwxr-xr-x 2 root root 4096 Mar 24 11:34 bin
drwxr-xr-x 2 root root 4096 Mar 24 12:52 config

drwxr-xr-x 3 root root 4096 Mar 24 11:34 lib
-rw-rw-r-- 1 root root 11358 Feb 2 17:24 LICENSE.txt
-rw-rw-r-- 1 root root 150 Feb 2 17:24 NOTICE.txt
-rw-rw-r-- 1 root root 8700 Feb 2 17:24 README.textile
[root@node01 elasticsearch]# /usr/local/elasticsearch/bin/elasticsearch
[root@node01 elasticsearch]
如果要elasticsearch在后台运行则只需要添加-d，即:
[root@node01 elasticsearch]# /usr/local/elasticsearch/bin/elasticsearch -d
启动之后查看端口状态:
[root@node01 elasticsearch]# netstat -lpnut|grep java
tcp 0 0 :::9300 :::* LISTEN 26868/java
tcp 0 0 :::9200 :::* LISTEN 26868/java
udp 0 0 :::54328 :::* LISTEN 26868/java
[root@node01 elasticsearch]#
访问查看状态信息:
[root@node01 elasticsearch]# curl http://10.0.0.41:9200
{
"status" : 200,
"name" : "node01",
"cluster_name" : "elasticsearch",
"version" : {
"number" : "1.7.5",
"build_hash" : "00f95f4ffca6de89d68b7ccaf80d148f1f70e4d4",
"build_timestamp" : "2016-02-02T09:55:30Z",
"build_snapshot" : false,
"lucene_version" : "4.10.4"
},
"tagline" : "You Know, for Search"
}
[root@node01 elasticsearch]#
④管理elasticsearch服务的脚本(该部分可选)
[root@node01 elasticsearch]# git clone https://github.com/elastic/elasticsearch-servicewrapper

插件能额外扩展elasticsearch功能，提供各类功能等等。有三种类型的插件：
1. java插件
只包含JAR文件，必须在集群中每个节点上安装而且需要重启才能使插件生效。
2. 网站插件
这类插件包含静态web内容，如js、css、html等等，可以直接从elasticsearch服务，如head插件。只需在一个节点上安装，不需要重启服务。可以通过下面的URL访问，如：http://node-ip:9200/_plugin/plugin_name
3. 混合插件
顾名思义，就是包含上面两种的插件。
安装elasticsearch插件Marvel:

logstash快速入门
官方建议yum安装:
Download and install the public signing key:
rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch
Add the following in your /etc/yum.repos.d/ directory in a file with a .repo suffix, for example logstash.repo
[logstash-2.2]
name=Logstash repository for 2.2.x packages
baseurl=http://packages.elastic.co/logstash/2.2/centos
gpgcheck=1
gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch
enabled=1
And your repository is ready for use. You can install it with:
yum install logstash
我这里采用源码解压安装: web01上部署nginx和logstash
[root@web01 tools]# tar xf logstash-2.1.3.tar.gz

logstash配置文件格式:
input { stdin { } }
output {
elasticsearch { hosts => ["localhost:9200"] }
stdout { codec => rubydebug }
}
配置文件结构:
# This is a comment. You should use comments to describe
# parts of your configuration.
input {
...
}
filter {
...
}
output {
...
}
插件的结构:
input {
file {
path => "/var/log/messages"
type => "syslog"
}
file {
path => "/var/log/apache/access.log"
type => "apache"
}
}
插件的数据结构:
数组array
Example:
path => [ "/var/log/messages", "/var/log/*.log" ]
path => "/data/mysql/mysql.log"
布尔类型
Example:
ssl_enable => true
字节
Examples:
my_bytes => "1113" # 1113 bytes
my_bytes => "10MiB" # 10485760 bytes
my_bytes => "100kib" # 102400 bytes
my_bytes => "180 mb" # 180000000 bytes
codeC
Example:
codec => "json"
HASH
Example:
match => {
"field1" => "value1"
"field2" => "value2"
...
}
Number
Numbers must be valid numeric values (floating point or integer).
Example:
port => 33
Password
A password is a string with a single value that is not logged or printed.
Example:
my_password => "password"
Pathedit
A path is a string that represents a valid operating system path.
Example:
my_path => "/tmp/logstash"
String
A string must be a single character sequence. Note that string values are enclosed in quotes, either double or single. Literal quotes in the string need to be escaped with a backslash if they are of the same kind as the string delimiter, i.e. single quotes within a single-quoted string need to be escaped as well as double quotes within a double-quoted string.
Example:
name => "Hello world"
name => 'It\'s a beautiful day'
Comments
Comments are the same as in perl, ruby, and python. A comment starts with a # character, and does not need to be at the beginning of a line. For example:
# this is a comment
input { # comments can appear at the end of a line, too
# ...
}
logstash版本不同，插件也会不同，我这里用的logstash-2.1.3.tar.gz
https://www.elastic.co/guide/en/logstash/2.1/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-hosts
logstash的启动方式为:
/usr/local/logstash/bin/logstash -f /usr/local/logstash/logstash.conf &
使用方法如下:
[root@node01 ~]# /usr/local/logstash/bin/logstash -t
Error: Usage:
/bin/logstash agent [OPTIONS]
Options:
-f, --config CONFIG_PATH Load the logstash config from a specific file
or directory. If a directory is given, all
files in that directory will be concatenated
in lexicographical order and then parsed as a
single config file. You can also specify
wildcards (globs) and any matched files will
be loaded in the order described above.
-e CONFIG_STRING Use the given string as the configuration
data. Same syntax as the config file. If no
input is specified, then the following is
used as the default input:
"input { stdin { type => stdin } }"
and if no output is specified, then the
following is used as the default output:
"output { stdout { codec => rubydebug } }"
If you wish to use both defaults, please use
the empty string for the '-e' flag.
(default: "")
-w, --filterworkers COUNT Sets the number of filter workers to run.
(default: 0)
-l, --log FILE Write logstash internal logs to the given
file. Without this flag, logstash will emit
logs to standard output.
-v Increase verbosity of logstash internal logs.
Specifying once will show 'informational'
logs. Specifying twice will show 'debug'
logs. This flag is deprecated. You should use
--verbose or --debug instead.
--quiet Quieter logstash logging. This causes only
errors to be emitted.
--verbose More verbose logging. This causes 'info'
level logs to be emitted.
--debug Most verbose logging. This causes 'debug'
level logs to be emitted.
-V, --version Emit the version of logstash and its friends,
then exit.
-p, --pluginpath PATH A path of where to find plugins. This flag
can be given multiple times to include
multiple paths. Plugins are expected to be
in a specific directory hierarchy:
'PATH/logstash/TYPE/NAME.rb' where TYPE is
'inputs' 'filters', 'outputs' or 'codecs'
and NAME is the name of the plugin.
-t, --configtest Check configuration for valid syntax and then exit.
--[no-]allow-unsafe-shutdown Force logstash to exit during shutdown even
if there are still inflight events in memory.
By default, logstash will refuse to quit until all
received events have been pushed to the outputs.

redis的安装和配置：
[root@kibana ~]#tar xf redis-3.0.7.tar.gz
[root@kibana ~]#cd redis-3.0.7
[root@kibana ~]#make MALLOC=jemalloc
[root@kibana ~]#make PREFIX=/application/redis-3.0.7 install
[root@kibana ~]#ln -s /application/redis-3.0.7 /application/redis
[root@kibana ~]#echo "export PATH=/application/redis/bin:$PATH" >>/etc/profile
[root@kibana ~]#source /etc/profile
[root@kibana ~]#mkdir -p /application/redis/conf
[root@kibana ~]#cp redis.conf /application/redis/conf/
[root@kibana ~]#vim /application/redis/conf/redis.conf
修改bind地址，为本机ip地址
[root@kibana ~]#redis-server /application/redis/conf/redis.conf &
切换到node01，登录node02的redis服务
[root@kibana ~]# redis-cli -h 10.0.0.44 -p 6379
10.0.0.11:6379> info
# Server
redis_version:3.0.7
redis_git_sha1:00000000
修改web01上logstash配置文件如下:
[root@web01 ~]# vim /usr/local/logstash/conf/logstash.conf
input {
file {
#type => "accesslog"
path => "/application/nginx/logs/access.log"
start_position => "beginning"
}
}
output {
redis {
data_type => "list"
key => "system-messages"
host => "10.0.0.44"
port => "6379"
db => "0"
}
}
[root@web01 ~]#
这里用nginx访问日志作为测试，定义输入文件为"/application/nginx/logs/access.log ",输出文件存储到redis里面，定义key为 "system-messages",host为10.0.0.44,端口6379，存储数据库库为db=0。
保证nginx是运行状态:
[root@web01 ~]# ps -ef|grep nginxroot 1109 1 0 12:59 ? 00:00:00 nginx: master process /application/nginx/sbin/nginxnobody 1113 1109 0 12:59 ? 00:00:00 nginx: worker process nobody 1114 1109 0 12:59 ? 00:00:00 nginx: worker process nobody 1115 1109 0 12:59 ? 00:00:00 nginx: worker process nobody 1116 1109 0 12:59 ? 00:00:00 nginx: worker process root 1572 1185 0 14:06 pts/0 00:00:00 grep nginx[root@web01 ~]# [root@web01 ~]# tail -f /application/nginx/logs/access.log 10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"10.0.0.10 - - [17/Aug/2016:14:10:02 +0800] "GET /index.html HTTP/1.0" 200 612 "-" "ApacheBench/2.3"[root@web01 ~]#
登录redis，查看数据是否已经传入到redis上:
[root@kibana ~]# redis-cli
127.0.0.1:6379> keys *
1) "system-messages"
127.0.0.1:6379>
127.0.0.1:6379>
127.0.0.1:6379> keys *
1) "system-messages"
127.0.0.1:6379>
发现通过浏览器访问的日志已经存入到了redis中，这一步实现日志的转存，下一步实现日志的从redis中通过logstash转存到elasticsearch中
以上实现了数据从数据源（access.log）中转存到redis中，下一步实现从redis中转存到elasticsearch中
这里在logstash上开启一个logstash，并且编写配置文件/usr/local/logstash/logstash.conf
[root@logstash ~]# cd /usr/local/logstash
[root@logstash logstash]# pwd
/usr/local/logstash
[root@logstash logstash]#
[root@node02 conf]# ps -ef|grep logstash
root 43072 42030 0 15:46 pts/1 00:00:00 grep logstash
[root@node02 conf]# cat /usr/local/logstash/logstash.conf
input {
redis {
data_type => "list"
key => "system-messages"
host => "10.0.0.44"
port => "6379"
db => "0"
}
}
output {
elasticsearch {
hosts => "10.0.0.41"
#protocol => "http"
index => "redis-messages-%{+YYYY.MM.dd}"
}
}
[root@logstash conf]#
说明:定义数据写入文件为redis,对应的键和主机以及端口如下:
redis {
data_type => "list"
key => "system-messages"
host => "10.0.0.44"
port => "6379"
db => "0"
}
数据输出到 elasticsearch中，具体配置为:
elasticsearch {
hosts => "10.0.0.41"
index => "system-redis-messages-%{+YYYY.MM.dd}"
}
启动logstash进行日志收集
[root@logstash conf]# /usr/local/logstash/bin/logstash -f /usr/local/logstash/conf/logstash.conf &

root 1339 1141 0 14:14 pts/0 00:00:00 grep logstash
[root@logstash logstash]#
再回过来查看redis的db中的数据是否已经转存过去（即存储到elasticserach中）
127.0.0.1:6379> LLEN system-messages
(integer) 0
127.0.0.1:6379>
127.0.0.1:6379>
127.0.0.1:6379> keys *
(empty list or set)
127.0.0.1:6379>
从上述输入可以知道数据应转存到elasticsearch中，下面我可以进行查看:
进一步查看日志信息:
logstash收集json格式的nginx日志，然后将日志转存到elasticsearch中
json格式分割nginx日志配置参数:
log_format logstash_json '{ "@timestamp": "$time_local", '

'"body_bytes_sent":"$body_bytes_sent", '
'"http_x_forwarded_for": "$http_x_forwarded_for", '
'"http_user_agent": "$http_user_agent" } }';
修改后的nginx配置文件为:
[root@web01 conf]# pwd
/application/nginx/conf
[root@web01 conf]# cat nginx.conf
worker_processes 4;

数据成功写入redis，接下来将redis数据写入elasticsearch中
在logstash主机上编写logstash配置文件
[root@logstash]#cd /usr/local/logstash/conf
[root@logstash conf]# cat logstash.conf
input {
redis {
data_type => "list"
key => "system-messages"
host => "10.0.0.44"
port => "6379"
db => "0"
}
}
output {
elasticsearch {
hosts => "10.0.0.41"
index => "nginx-access-log-%{+YYYY.MM.dd}"
}
}
[root@logstash conf]#
测试文件是否正确，然后重启logstash
[root@logstash conf]# /usr/local/logstash/bin/logstash -t -f /usr/local/logstash/conf/logstash.conf
Configuration OK
[root@logstash conf]#
[root@logstash conf]# /usr/local/logstash/bin/logstash -f /usr/local/logstash/conf/logstash.conf &

浏览器输入http://192.168.0.44:5601/
点击“create”创建nginx-access-log索引
切换到discover
在这里可以选择"today、Laster minutes等时间"，例如我们选择"Laster minutes";
点击“Laster minutes”
y因为我们创建的索引是在15分钟以内的，所以这里显示找不到结果，这里选择today，时间选长一点，再看
点击“today”
下面是根据需要列出以前实验的操作步骤，仅供参考
如果根据需求显示（默认是显示全部):这里用add来选择要显示的内容
搜索功能，比如搜索状态为404的
搜索状态为200的
总结ELKStack工作流程
元数据（tomcat、Apache、PHP等服务器的日志文件log）-------->logstash将原始数据写入到redis中，然后通过logstash将redis中的数据写入到elasticsearch，最后通过kibana对elasticsearch数据进行分析整理，并展示出来
补充elasticsearch配置文件注释:
elasticsearch的config文件夹里面有两个配置文 件：elasticsearch.yml和logging.yml，第一个是es的基本配置文件，第二个是日志配置文件，
es也是使用log4j来记录日 志的，所以logging.yml里的设置按普通log4j配置文件来设置就行了。下面主要讲解下elasticsearch.yml这个文件中可配置的 东西。
cluster.name: elasticsearch
配置es的集群名称，默认是elasticsearch，es会自动发现在同一网段下的es，如果在同一网段下有多个集群，就可以用这个属性来区分不同的集群。
node.name: "Franz Kafka"
节点名，默认随机指定一个name列表中名字，该列表在es的jar包中config文件夹里name.txt文件中，其中有很多作者添加的有趣名字。
node.master: true
指定该节点是否有资格被选举成为node，默认是true，es是默认集群中的第一台机器为master，如果这台机挂了就会重新选举master。
node.data: true
指定该节点是否存储索引数据，默认为true。
index.number_of_shards: 5
设置默认索引分片个数，默认为5片。
index.number_of_replicas: 1
设置默认索引副本个数，默认为1个副本。
path.conf: /path/to/conf
设置配置文件的存储路径，默认是es根目录下的config文件夹。
path.data: /path/to/data
设置索引数据的存储路径，默认是es根目录下的data文件夹，可以设置多个存储路径，用逗号隔开，例：
path.data: /path/to/data1,/path/to/data2
path.work: /path/to/work
设置临时文件的存储路径，默认是es根目录下的work文件夹。
path.logs: /path/to/logs
设置日志文件的存储路径，默认是es根目录下的logs文件夹
path.plugins: /path/to/plugins
设置插件的存放路径，默认是es根目录下的plugins文件夹
bootstrap.mlockall: true
设置为true来锁住内存。因为当jvm开始swapping时es的效率 会降低，所以要保证它不swap，可以把ES_MIN_MEM和ES_MAX_MEM两个环境变量设置成同一个值，并且保证机器有足够的内存分配给es。 同时也要允许elasticsearch的进程可以锁住内存，linux下可以通过`ulimit -l unlimited`命令。
network.bind_host: 192.168.0.1
设置绑定的ip地址，可以是ipv4或ipv6的，默认为0.0.0.0。
network.publish_host: 192.168.0.1
设置其它节点和该节点交互的ip地址，如果不设置它会自动判断，值必须是个真实的ip地址。
network.host: 192.168.0.1
这个参数是用来同时设置bind_host和publish_host上面两个参数。
transport.tcp.port: 9300
设置节点间交互的tcp端口，默认是9300。
transport.tcp.compress: true
设置是否压缩tcp传输时的数据，默认为false，不压缩。
http.port: 9200
设置对外服务的http端口，默认为9200。
http.max_content_length: 100mb
设置内容的最大容量，默认100mb
http.enabled: false
是否使用http协议对外提供服务，默认为true，开启。
gateway.type: local
gateway的类型，默认为local即为本地文件系统，可以设置为本地文件系统，分布式文件系统，hadoop的HDFS，和amazon的s3服务器，其它文件系统的设置方法下次再详细说。
gateway.recover_after_nodes: 1
设置集群中N个节点启动时进行数据恢复，默认为1。
gateway.recover_after_time: 5m
设置初始化数据恢复进程的超时时间，默认是5分钟。
gateway.expected_nodes: 2
设置这个集群中节点的数量，默认为2，一旦这N个节点启动，就会立即进行数据恢复。
cluster.routing.allocation.node_initial_primaries_recoveries: 4
初始化数据恢复时，并发恢复线程的个数，默认为4。
cluster.routing.allocation.node_concurrent_recoveries: 2
添加删除节点或负载均衡时并发恢复线程的个数，默认为4。
indices.recovery.max_size_per_sec: 0
设置数据恢复时限制的带宽，如入100mb，默认为0，即无限制。
indices.recovery.concurrent_streams: 5
设置这个参数来限制从其它分片恢复数据时最大同时打开并发流的个数，默认为5。
discovery.zen.minimum_master_nodes: 1
设置这个参数来保证集群中的节点可以知道其它N个有master资格的节点。默认为1，对于大的集群来说，可以设置大一点的值（2-4）
discovery.zen.ping.timeout: 3s
设置集群中自动发现其它节点时ping连接超时时间，默认为3秒，对于比较差的网络环境可以高点的值来防止自动发现时出错。
discovery.zen.ping.multicast.enabled: false
设置是否打开多播发现节点，默认是true。
discovery.zen.ping.unicast.hosts: ["host1", "host2:port", "host3[portX-portY]"]
设置集群中master节点的初始列表，可以通过这些节点来自动发现新加入集群的节点。
下面是一些查询时的慢日志参数设置
index.search.slowlog.level: TRACE
index.search.slowlog.threshold.query.warn: 10s
index.search.slowlog.threshold.query.info: 5s
index.search.slowlog.threshold.query.debug: 2s
index.search.slowlog.threshold.query.trace: 500ms
index.search.slowlog.threshold.fetch.warn: 1s
index.search.slowlog.threshold.fetch.info: 800ms
index.search.slowlog.threshold.fetch.debug:500ms
index.search.slowlog.threshold.fetch.trace: 200ms
