虚拟机 CentOS 6.5 安装搭建 Elasticsearch 6.2.2

时间：2022-09-13 00:06:04

1.安装jre

Elasticsearch（下文用ES简称代替） 的安装搭建环境要求JAVA环境，需要jre1.8以上，所以先从JAVA官网下载jre的rpm包

http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

下载rpm包后，上传到服务器的 /opt 目录下

服务器上切换到opt 目录下，使用rpm命令安装jre（安装的时候自己补全对应的rpm包的名字），安装完成后使用 命令 java -version 验证java的安装正确性

[root@elk2 ~]# cd /opt[root@elk2 opt]# rpm -ivh jre-8u161-linux-x64.rpm

Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

2.安装ES（官网有多种方法，随意选择）

打开ES官网https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html

根据官网的教程下载es的tar包，

虚拟机 CentOS 6.5 安装搭建 Elasticsearch 6.2.2

下载es的tar包

[root@elk2 opt]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.2.tar.gz

解压

[root@elk2 opt]#tar -xzf elasticsearch-6.2.2.tar.gz

解压成功后获得ES6.2.2文件夹

[root@elk2 opt]# ll总用量 90232drwxr-xr-x. 8 root root     4096 2月  17 03:03 elasticsearch-6.2.2-rw-r--r--. 1 root root 29049540 2月  28 11:30 elasticsearch-6.2.2.tar.gz-rw-r--r--. 1 root root 63333908 2月  28 11:30 jre-8u161-linux-x64.rpm

3.创建ES用户

默认ES 6.X 是不允许root用户运行的，否则ES运行的时候会报错，所以我们需要创建新的用户

[root@elk2 opt]# groupadd es[root@elk2 opt]# useradd es -g es[root@elk2 opt]# passwd es更改用户 es 的密码 。新的 密码：重新输入新的 密码：passwd： 所有的身份验证令牌已经成功更新。

4.修改ES目录权限

修改ES的根目录的权限

[root@elk2 opt]# chown -R es:es elasticsearch-6.2.2

切换当前用户为es ， 进入es的目录， 使用命令 

./bin/elasticsearch 就可以将ES 运行起来了

[root@elk2 opt]# su es[es@elk2 opt]$ cd elasticsearch-6.2.2[es@elk2 elasticsearch-6.2.2]$ ./bin/elasticsearch

正常的启动信息如下：

可以看到默认9200 9300 端口打开

[2018-02-28T11:56:02,537][INFO ][o.e.n.Node               ] [rAnzmAZ] starting ...[2018-02-28T11:56:02,717][INFO ][o.e.t.TransportService   ] [rAnzmAZ] publish_address {127.0.0.1:9300}, bound_addresses {[::1]:9300}, {127.0.0.1:9300}[2018-02-28T11:56:02,736][WARN ][o.e.b.BootstrapChecks    ] [rAnzmAZ] max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536][2018-02-28T11:56:02,737][WARN ][o.e.b.BootstrapChecks    ] [rAnzmAZ] max number of threads [1024] for user [es] is too low, increase to at least [4096][2018-02-28T11:56:02,737][WARN ][o.e.b.BootstrapChecks    ] [rAnzmAZ] max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144][2018-02-28T11:56:02,737][WARN ][o.e.b.BootstrapChecks    ] [rAnzmAZ] system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk[2018-02-28T11:56:05,848][INFO ][o.e.c.s.MasterService    ] [rAnzmAZ] zen-disco-elected-as-master ([0] nodes joined), reason: new_master {rAnzmAZ}{rAnzmAZLR2CCkXXZY1oxAA}{qLtHLrJXRuWme98YA2DxgQ}{127.0.0.1}{127.0.0.1:9300}[2018-02-28T11:56:05,854][INFO ][o.e.c.s.ClusterApplierService] [rAnzmAZ] new_master {rAnzmAZ}{rAnzmAZLR2CCkXXZY1oxAA}{qLtHLrJXRuWme98YA2DxgQ}{127.0.0.1}{127.0.0.1:9300}, reason: apply cluster state (from master [master {rAnzmAZ}{rAnzmAZLR2CCkXXZY1oxAA}{qLtHLrJXRuWme98YA2DxgQ}{127.0.0.1}{127.0.0.1:9300} committed version [1] source [zen-disco-elected-as-master ([0] nodes joined)]])[2018-02-28T11:56:05,906][INFO ][o.e.h.n.Netty4HttpServerTransport] [rAnzmAZ] publish_address {127.0.0.1:9200}, bound_addresses {[::1]:9200}, {127.0.0.1:9200}[2018-02-28T11:56:05,906][INFO ][o.e.n.Node               ] [rAnzmAZ] started[2018-02-28T11:56:05,935][INFO ][o.e.g.GatewayService     ] [rAnzmAZ] recovered [0] indices into cluster_state

可以验证一下服务是否正常

[root@elk2 ~]# curl -i "http://localhost:9200"
HTTP/1.1 200 OKcontent-type: application/json; charset=UTF-8content-length: 436{  "name" : "linux-2",  "cluster_name" : "li-application",  "cluster_uuid" : "LeGL4ApCTDS-Nj76INkZAg",  "version" : {    "number" : "6.2.2",    "build_hash" : "10b1edd",    "build_date" : "2018-02-16T19:01:30.685723Z",    "build_snapshot" : false,    "lucene_version" : "7.2.1",    "minimum_wire_compatibility_version" : "5.6.0",    "minimum_index_compatibility_version" : "5.0.0"  },  "tagline" : "You Know, for Search"}



ps 。后台运行ES，可以加入-p 命令 让es在后台运行， -p 参数 记录进程ID为一个文件

[es@elk2 elasticsearch-6.2.2]$ ./bin/elasticsearch -d -p pid

关闭后台运行ES，使用如下命令（前提是用上面的命令运行）：

[es@elk2 elasticsearch-6.2.2]$ kill `cat pid`

5.配置ElasticSearch，让ElasticSearch支持外网访问，加入集群等

修改配置文件elasticsearch.yml

[es@elk2 elasticsearch-6.2.2]$ vim config/elasticsearch.yml

去掉以下注释，修改以下配置（记得配置项名称冒号后面是有一个空格的，若没有空格会报错

cluster.name: li-application #集群名称，可以自行修改node.name: linux-2 #节点名称，自行修改network.host: 172.16.1.177 #主机地址，这里写本机IPhttp.port: 9200 #端口

修改后，再次启动ES后，会得到以下报错

[es@elk2 elasticsearch-6.2.2]$ ./bin/elasticsearch
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536][2]: max number of threads [1024] for user [es] is too low, increase to at least [4096][3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144][4]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

根据网上的各位大佬的解决办法，逐一去解决，使用root身份，执行以下操作

解决问题【1】【2】

[root@elk2 ~]# vim /etc/security/limits.conf

在文件未添加以下内容（开头es 为用户名）

es soft nofile 65536es hard nofile 131072es soft nproc 4096es hard nproc 4096

解决问题【3】

[root@elk2 ~]# sysctl -w vm.max_map_count=262144   [root@elk2 ~]# vim /etc/sysctl.conf     #让配置永久生效

在文末添加以下内容

vm.max_map_count=262144

解决问题【4】

Centos6不支持SecComp，而ES6默认bootstrap.system_call_filter为true

[es@elk2 elasticsearch-6.2.2]$ vim config/elasticsearch.yml

禁用：在elasticsearch.yml中配置bootstrap.system_call_filter为false，注意要在Memory下面: 

取消bootstrap.memory_lock的注释，添加bootstrap.system_call_filter 配置

bootstrap.memory_lock: false bootstrap.system_call_filter: false

再次启动es，成功启动

[es@elk2 elasticsearch-6.2.2]$ ./bin/elasticsearch
