原文地址：，转载烦请注明原文地址。

1. 安装配置JDK 8

（1）下载并解压缩

[root@node1 ~]# tar -zxvf jdk-8u112-linux-x64.tar.gz -C /opt

（2）编辑环境变量

vi /etc/profile.d/custom.sh

[root@node1 ~]# vi /etc/profile.d/custom.sh[root@node1 ~]# cat /etc/profile.d/custom.sh#!/bin/bash#java pathexport JAVA_HOME=/opt/jdk1.8.0_112export PATH=$PATH:$JAVA_HOME/binexport CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib

（3）生效

[root@node1 ~]# source /etc/profile.d/custom.sh

（4）查看JDK版本

[root@node1 ~]# java -versionjava version "1.8.0_112"Java(TM) SE Runtime Environment (build 1.8.0_112-b15)Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)[root@node1 ~]#

2. 创建用户

从5.0开始，ElasticSearch 安全级别提高了，不允许采用root帐号启动，所以我们要添加一个用户。

（1）创建bigdata 用户组

[root@node1 ~]# groupadd bigdata

（2）创建用户es

[root@node1 ~]# useradd es[root@node1 ~]# passwd esChanging password for user es.New password: BAD PASSWORD: The password is shorter than 8 charactersRetype new password: passwd: all authentication tokens updated successfully.[root@node1 ~]#

（3）将es用户添加到bigdata组

[root@node1 ~]# usermod -G bigdata es

（4）设置sudo权限

[root@node1 ~]# visudo

找到root ALL=(ALL) ALL一行，添加es用户，如下。

## Allow root to run any commands anywhereroot    ALL=(ALL)       ALLes      ALL=(ALL)       ALL

（5）切换用户

[root@node1 ~]# su es[es@node1 root]$ cd[es@node1 ~]$

3. ElasticSearch 6.x 软件包下载

（1）ElasticSearch官网

（2）下载ElasticSearch

[es@node1 ~]$ wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.1.1.tar.gz--2018-01-06 08:24:06--  https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.1.1.tar.gzResolving artifacts.elastic.co (artifacts.elastic.co)... 54.225.188.6, 54.243.108.41, 184.72.218.26, ...Connecting to artifacts.elastic.co (artifacts.elastic.co)|54.225.188.6|:443... connected.HTTP request sent, awaiting response... 200 OKLength: 28462503 (27M) [application/x-gzip]Saving to: ‘elasticsearch-6.1.1.tar.gz.1’100%[===================================================================================================================================================>] 28,462,503   232KB/s   in 3m 33s 2018-01-06 08:27:42 (130 KB/s) - ‘elasticsearch-6.1.1.tar.gz.1’ saved [28462503/28462503][es@node1 ~]$

（3）解压缩

tar -zxvf elasticsearch-6.1.1.tar.gz

[es@node1 ~]$ tar -zxvf elasticsearch-6.1.1.tar.gz[es@node1 ~]$ sudo mv elasticsearch-6.1.1 /opt

（4）修改目录权限

更改elasticsearch-6.1.1文件夹以及内部文件的所属用户为es, 用户组组为bigdata，-R表示逐级（N层目录）

[es@node1 ~]$ sudo chown -R es:bigdata /opt/elasticsearch-6.1.1[es@node1 ~]$ ll /opt/elasticsearch-6.1.1total 220drwxr-xr-x  2 es bigdata   4096 Jan  6 08:35 bindrwxr-xr-x  2 es bigdata     75 Dec 17 15:24 configdrwxr-xr-x  2 es bigdata   4096 Dec 17 15:24 lib-rw-r--r--  1 es bigdata  11358 Dec 17 15:22 LICENSE.txtdrwxr-xr-x 15 es bigdata    272 Dec 17 15:24 modules-rw-r--r--  1 es bigdata 191887 Dec 17 15:24 NOTICE.txtdrwxr-xr-x  2 es bigdata      6 Dec 17 15:24 plugins-rw-r--r--  1 es bigdata   9326 Dec 17 15:22 README.textile[es@node1 ~]$

4. ElasticSearch 配置

（1）修改elasticsearch.yml

[es@node1 elasticsearch-6.1.1]$ vi config/elasticsearch.yml

修改network.host和http.port

# Set the bind address to a specific IP (IPv4 or IPv6):#network.host: 192.168.80.131## Set a custom port for HTTP:#http.port: 9200

保存退出。

（2）修改/etc/sysctl.conf

切换到root用户，

[root@node1 elasticsearch-6.1.1]# vi /etc/sysctl.conf

添加内容如下：

vm.max_map_count=262144

用命令sysctl -p 生效

[root@node1 ~]# sysctl -pnet.ipv4.ip_forward = 0net.ipv4.conf.default.rp_filter = 1net.ipv4.conf.default.accept_source_route = 0kernel.sysrq = 0kernel.core_uses_pid = 1net.ipv4.tcp_syncookies = 1kernel.msgmnb = 65536kernel.msgmax = 65536kernel.shmmax = 68719476736kernel.shmall = 4294967296vm.max_map_count = 262144[root@node1 ~]#

（3）修改文件/etc/security/limits.conf

[root@node1 logs]# vi /etc/security/limits.conf

添加如下内容

* hard nofile 65536* soft nofile 65536* soft nproc 2048* hard nproc 4096# End of file

5.ElasticSearch启动与停止

（1）直接启动

[es@node1 elasticsearch-6.1.1]$ bin/elasticsearch[2018-01-06T08:53:21,796][INFO ][o.e.n.Node               ] [] initializing ...[2018-01-06T08:53:21,941][INFO ][o.e.e.NodeEnvironment    ] [cNWkQjt] using [1] data paths, mounts [[/ (rootfs)]], net usable_space [13.8gb], net total_space [21.9gb], types [rootfs][2018-01-06T08:53:21,941][INFO ][o.e.e.NodeEnvironment    ] [cNWkQjt] heap size [1007.3mb], compressed ordinary object pointers [true][2018-01-06T08:53:21,945][INFO ][o.e.n.Node               ] node name [cNWkQjt] derived from node ID [cNWkQjt9SzKFNtyx8IIu-A]; set [node.name] to override[2018-01-06T08:53:21,945][INFO ][o.e.n.Node               ] version[6.1.1], pid[2752], build[bd92e7f/2017-12-17T20:23:25.338Z], OS[Linux/3.10.0-514.el7.x86_64/amd64], JVM[Oracle Corporation/Java HotSpot(TM) 64-Bit Server VM/1.8.0_112/25.112-b15][2018-01-06T08:53:21,946][INFO ][o.e.n.Node               ] JVM arguments [-Xms1g, -Xmx1g, -XX:+UseConcMarkSweepGC, -XX:CMSInitiatingOccupancyFraction=75, -XX:+UseCMSInitiatingOccupancyOnly, -XX:+AlwaysPreTouch, -Xss1m, -Djava.awt.headless=true, -Dfile.encoding=UTF-8, -Djna.nosys=true, -XX:-OmitStackTraceInFastThrow, -Dio.netty.noUnsafe=true, -Dio.netty.noKeySetOptimization=true, -Dio.netty.recycler.maxCapacityPerThread=0, -Dlog4j.shutdownHookEnabled=false, -Dlog4j2.disable.jmx=true, -XX:+HeapDumpOnOutOfMemoryError, -Des.path.home=/opt/elasticsearch-6.1.1, -Des.path.conf=/opt/elasticsearch-6.1.1/config][2018-01-06T08:53:23,614][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [aggs-matrix-stats][2018-01-06T08:53:23,615][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [analysis-common][2018-01-06T08:53:23,615][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [ingest-common][2018-01-06T08:53:23,615][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [lang-expression][2018-01-06T08:53:23,615][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [lang-mustache][2018-01-06T08:53:23,615][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [lang-painless][2018-01-06T08:53:23,616][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [mapper-extras][2018-01-06T08:53:23,616][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [parent-join][2018-01-06T08:53:23,616][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [percolator][2018-01-06T08:53:23,616][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [reindex][2018-01-06T08:53:23,616][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [repository-url][2018-01-06T08:53:23,617][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [transport-netty4][2018-01-06T08:53:23,617][INFO ][o.e.p.PluginsService     ] [cNWkQjt] loaded module [tribe][2018-01-06T08:53:23,618][INFO ][o.e.p.PluginsService     ] [cNWkQjt] no plugins loaded[2018-01-06T08:53:26,588][INFO ][o.e.d.DiscoveryModule    ] [cNWkQjt] using discovery type [zen][2018-01-06T08:53:27,618][INFO ][o.e.n.Node               ] initialized[2018-01-06T08:53:27,619][INFO ][o.e.n.Node               ] [cNWkQjt] starting ...[2018-01-06T08:53:27,836][INFO ][o.e.t.TransportService   ] [cNWkQjt] publish_address {192.168.80.131:9300}, bound_addresses {192.168.80.131:9300}[2018-01-06T08:53:27,860][INFO ][o.e.b.BootstrapChecks    ] [cNWkQjt] bound or publishing to a non-loopback or non-link-local address, enforcing bootstrap checks[2018-01-06T08:53:30,984][INFO ][o.e.c.s.MasterService    ] [cNWkQjt] zen-disco-elected-as-master ([0] nodes joined), reason: new_master {cNWkQjt}{cNWkQjt9SzKFNtyx8IIu-A}{eRRknS3vQ52ffJA8I2u9iQ}{192.168.80.131}{192.168.80.131:9300}[2018-01-06T08:53:30,992][INFO ][o.e.c.s.ClusterApplierService] [cNWkQjt] new_master {cNWkQjt}{cNWkQjt9SzKFNtyx8IIu-A}{eRRknS3vQ52ffJA8I2u9iQ}{192.168.80.131}{192.168.80.131:9300}, reason: apply cluster state (from master [master {cNWkQjt}{cNWkQjt9SzKFNtyx8IIu-A}{eRRknS3vQ52ffJA8I2u9iQ}{192.168.80.131}{192.168.80.131:9300} committed version [1] source [zen-disco-elected-as-master ([0] nodes joined)]])[2018-01-06T08:53:31,073][INFO ][o.e.h.n.Netty4HttpServerTransport] [cNWkQjt] publish_address {192.168.80.131:9200}, bound_addresses {192.168.80.131:9200}[2018-01-06T08:53:31,073][INFO ][o.e.n.Node               ] [cNWkQjt] started[2018-01-06T08:53:31,094][INFO ][o.e.g.GatewayService     ] [cNWkQjt] recovered [0] indices into cluster_state

（2）停止

ctrl+c停止。

^C[2018-01-06T08:55:24,513][INFO ][o.e.n.Node               ] [cNWkQjt] stopping ...[2018-01-06T08:55:24,568][INFO ][o.e.n.Node               ] [cNWkQjt] stopped[2018-01-06T08:55:24,569][INFO ][o.e.n.Node               ] [cNWkQjt] closing ...[2018-01-06T08:55:24,585][INFO ][o.e.n.Node               ] [cNWkQjt] closed[es@node1 elasticsearch-6.1.1]$

（3）后台运行

可以通过参数-d后台运行

[es@node1 elasticsearch-6.1.1]$ bin/elasticsearch -d

（4）查询进程

[es@node1 elasticsearch-6.1.1]$ jps3120 Elasticsearch3135 Jps[es@node1 elasticsearch-6.1.1]$

6. 验证

（1）使用curl验证

[es@node1 elasticsearch-6.1.1]$ curl http://192.168.80.131:9200{  "name" : "cNWkQjt",  "cluster_name" : "elasticsearch",  "cluster_uuid" : "Kd_e-tqxSx20dl_HjAt1ZQ",  "version" : {    "number" : "6.1.1",    "build_hash" : "bd92e7f",    "build_date" : "2017-12-17T20:23:25.338Z",    "build_snapshot" : false,    "lucene_version" : "7.1.0",    "minimum_wire_compatibility_version" : "5.6.0",    "minimum_index_compatibility_version" : "5.0.0"  },  "tagline" : "You Know, for Search"}[es@node1 elasticsearch-6.1.1]$

（2）浏览器验证

如果在Windows平台通过浏览器打开，需要配置hosts。编辑C:\Windows\System32\drivers\etc\hosts 添加

192.168.80.131  node1

6.问题解决

（1）jps看不到Java进程

[es@node1 elasticsearch-6.1.1]$ bin/elasticsearch -d[es@node1 elasticsearch-6.1.1]$ jps[es@node1 elasticsearch-6.1.1]$ jps[es@node1 elasticsearch-6.1.1]$ ps -aux|grep elasticsearches         2930  125 65.2 3627480 1218920 pts/0 Sl   09:33   0:15 /opt/jdk1.8.0_112/bin/java -Xms1g -Xmx1g -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+AlwaysPreTouch -server -Xss1m -Djava.awt.headless=true -Dfile.encoding=UTF-8 -Djna.nosys=true -XX:-OmitStackTraceInFastThrow -Dio.netty.noUnsafe=true -Dio.netty.noKeySetOptimization=true -Dio.netty.recycler.maxCapacityPerThread=0 -Dlog4j.shutdownHookEnabled=false -Dlog4j2.disable.jmx=true -XX:+HeapDumpOnOutOfMemoryError -Des.path.home=/opt/elasticsearch-6.1.1 -Des.path.conf=/opt/elasticsearch-6.1.1/config -cp /opt/elasticsearch-6.1.1/lib/* org.elasticsearch.bootstrap.Elasticsearch -des         2998  0.0  0.0 112660   968 pts/0    S+   09:33   0:00 grep --color=auto elasticsearch[es@node1 elasticsearch-6.1.1]$

查找原因

原因是当前es用户没有/tmp/hsperfdata_es目录的写权限。

解决办法：

[root@node1 ~]# chown -R es:es /tmp/hsperfdata_es
