一.实验环境说明
1>.测试集群规模说明
搭建ElasticSearch集群最少得有2台服务器，我这里使用3台测试机，其主机名如下所示:
es101.yinzhengjie.org.cn
es102.yinzhengjie.org.cn
es103.yinzhengjie.org.cn
操作环境使用Ubuntu 18.04发行版本，每台节点自行部署JDK和Elasticsearch服务。
[root@es101.yinzhengjie.com ~]# grep yinzhengjie.com /etc/hosts 172.200.5.101 es101.yinzhengjie.com 172.200.5.102 es102.yinzhengjie.com 172.200.5.103 es103.yinzhengjie.com [root@es101.yinzhengjie.com ~]#

二.部署分布式ElasticSearch集群
1>.修改es101.yinzhengjie.org.cn的配置文件
[root@es101.yinzhengjie.com ~]# vim /etc/elasticsearch/elasticsearch.yml [root@es101.yinzhengjie.com ~]# [root@es101.yinzhengjie.com ~]# egrep -v "^#|^$" /etc/elasticsearch/elasticsearch.yml cluster.name: yinzhengjie-es #指定集群名称 node.name: es101.yinzhengjie.com #指定节点名称，通常设置为当前主机名即可 path.data: /yinzhengjie/data/elasticsearch/data #指定ES的数据存储目录，生产环境建议单独使用一块磁盘存储，或者使用磁盘阵列存储均可。 path.logs: /yinzhengjie/data/elasticsearch/log #指定日志存储路径 network.host: 172.200.5.101 #建议大家直接写当前的IP地址，如果有多个地址也可以使用"0.0.0.0",可以指定为当前的主机名，但是会设计到“/etc/hosts"找对应的解析地址. discovery.zen.ping.unicast.hosts: ["172.200.5.101", "172.200.5.102","172.200.5.103"] #设置单播地址，建议集群有多少个节点就写多少个地址 [root@es101.yinzhengjie.com ~]#
[root@es102.yinzhengjie.com ~]# egrep -v "^#|^$" /etc/elasticsearch/elasticsearch.yml cluster.name: yinzhengjie-es node.name: es102.yinzhengjie.com path.data: /yinzhengjie/data/elasticsearch/data path.logs: /yinzhengjie/data/elasticsearch/log network.host: 172.200.5.102 discovery.zen.ping.unicast.hosts: ["172.200.5.101", "172.200.5.102","172.200.5.103"] [root@es102.yinzhengjie.com ~]#
[root@es103.yinzhengjie.com ~]# egrep -v "^#|^$" /etc/elasticsearch/elasticsearch.yml cluster.name: yinzhengjie-es node.name: es103.yinzhengjie.com path.data: /yinzhengjie/data/elasticsearch/data path.logs: /yinzhengjie/data/elasticsearch/log network.host: 172.200.5.103 discovery.zen.ping.unicast.hosts: ["172.200.5.101", "172.200.5.102","172.200.5.103"] [root@es103.yinzhengjie.com ~]#
2>.修改es102.yinzhengjie.org.cn的配置文件
[root@es102.yinzhengjie.com ~]# egrep -v "^#|^$" /etc/elasticsearch/elasticsearch.yml cluster.name: yinzhengjie-es node.name: es102.yinzhengjie.com path.data: /yinzhengjie/data/elasticsearch/data path.logs: /yinzhengjie/data/elasticsearch/log network.host: 172.200.5.102 discovery.zen.ping.unicast.hosts: ["172.200.5.101", "172.200.5.102","172.200.5.103"] [root@es102.yinzhengjie.com ~]#
3>.修改es103.yinzhengjie.org.cn的配置文件
[root@es103.yinzhengjie.com ~]# egrep -v "^#|^$" /etc/elasticsearch/elasticsearch.yml cluster.name: yinzhengjie-es node.name: es103.yinzhengjie.com path.data: /yinzhengjie/data/elasticsearch/data path.logs: /yinzhengjie/data/elasticsearch/log network.host: 172.200.5.103 discovery.zen.ping.unicast.hosts: ["172.200.5.101", "172.200.5.102","172.200.5.103"] [root@es103.yinzhengjie.com ~]#
4>.各节点创建elasticsearch的数据目录并修改授权
[root@es101.yinzhengjie.com ~]# mkdir -pv /yinzhengjie/data/elasticsearch/{data,log} mkdir: created directory '/yinzhengjie/data' mkdir: created directory '/yinzhengjie/data/elasticsearch' mkdir: created directory '/yinzhengjie/data/elasticsearch/data' mkdir: created directory '/yinzhengjie/data/elasticsearch/log' [root@es101.yinzhengjie.com ~]# [root@es101.yinzhengjie.com ~]# ll /yinzhengjie/data/elasticsearch/ total 0 drwxr-xr-x 4 root root 29 Jun 3 02:44 ./ drwxr-xr-x 3 root root 27 Jun 3 02:44 ../ drwxr-xr-x 2 root root 6 Jun 3 02:44 data/ drwxr-xr-x 2 root root 6 Jun 3 02:44 log/ [root@es101.yinzhengjie.com ~]# [root@es101.yinzhengjie.com ~]#
[root@es101.yinzhengjie.com ~]# ll /yinzhengjie/data/elasticsearch/ total 0 drwxr-xr-x 4 root root 29 Jun 3 02:44 ./ drwxr-xr-x 3 root root 27 Jun 3 02:44 ../ drwxr-xr-x 2 root root 6 Jun 3 02:44 data/ drwxr-xr-x 2 root root 6 Jun 3 02:44 log/ [root@es101.yinzhengjie.com ~]# [root@es101.yinzhengjie.com ~]# chown -R elasticsearch:elasticsearch /yinzhengjie/data/elasticsearch/ [root@es101.yinzhengjie.com ~]# [root@es101.yinzhengjie.com ~]# ll /yinzhengjie/data/elasticsearch/ total 0 drwxr-xr-x 4 elasticsearch elasticsearch 29 Jun 3 02:44 ./ drwxr-xr-x 3 root root 27 Jun 3 02:44 ../ drwxr-xr-x 2 elasticsearch elasticsearch 6 Jun 3 02:44 data/ drwxr-xr-x 2 elasticsearch elasticsearch 6 Jun 3 02:44 log/ [root@es101.yinzhengjie.com ~]# [root@es101.yinzhengjie.com ~]#
5>.各节点启动Elasticsearch服务(第一次启动会很慢，因为要初始化目录信息，请耐心等待)
[root@es101.yinzhengjie.com ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 127.0.0.53%lo:53 0.0.0.0:* LISTEN 0 128 0.0.0.0:22 0.0.0.0:* LISTEN 0 128 [::]:22 [::]:* [root@es101.yinzhengjie.com ~]# [root@es101.yinzhengjie.com ~]# systemctl start elasticsearch [root@es101.yinzhengjie.com ~]# [root@es101.yinzhengjie.com ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 127.0.0.53%lo:53 0.0.0.0:* LISTEN 0 128 0.0.0.0:22 0.0.0.0:* LISTEN 0 128 [::ffff:172.200.5.101]:9200 *:* LISTEN 0 128 [::ffff:172.200.5.101]:9300 *:* LISTEN 0 128 [::]:22 [::]:* [root@es101.yinzhengjie.com ~]#

6>.使用Restful API查看ES集群的工作状态
查看ES可以查看的方法： http://es101.yinzhengjie.com:9200/_cat
查看各个node节点信息，不显示头部信息: http://es101.yinzhengjie.com:9200/_cat/nodes
查看各个node节点信息，显示头部信息: http://es101.yinzhengjie.com:9200/_cat/nodes?v
显示主节点信息，显示头部信息: http://es101.yinzhengjie.com:9200/_cat/master?v
查看集群的节点状态: http://es101.yinzhengjie.com:9200/_cat/health?v
三.配置Elasticsearch的内存
1>.修改Elasticsearch服务的堆内存
[root@es103.yinzhengjie.com ~]# egrep -v "^#|^$" /etc/elasticsearch/jvm.options | head -2 -Xms1g -Xmx1g [root@es103.yinzhengjie.com ~]# [root@es103.yinzhengjie.com ~]# vim /etc/elasticsearch/jvm.options [root@es103.yinzhengjie.com ~]# [root@es103.yinzhengjie.com ~]# egrep -v "^#|^$" /etc/elasticsearch/jvm.options | head -2 #修改堆内存大小，生产环境中官方建议不要超过物理内存的一半，比如32G内存则最少分配16G给ES服务。最大不建议超过32G。 -Xms2g -Xmx2g [root@es103.yinzhengjie.com ~]#
2>.修改elaticsearch的配置文件
[root@es103.yinzhengjie.com ~]# egrep -v "^#|^$" /etc/elasticsearch/jvm.options | head -2 -Xms2g -Xmx2g [root@es103.yinzhengjie.com ~]# [root@es103.yinzhengjie.com ~]# vim /etc/elasticsearch/jvm.options [root@es103.yinzhengjie.com ~]# [root@es103.yinzhengjie.com ~]# egrep -v "^#|^$" /etc/elasticsearch/jvm.options | head -2 -Xms2g -Xmx2g [root@es103.yinzhengjie.com ~]#
[root@es103.yinzhengjie.com ~]# grep bootstrap.memory_lock /etc/elasticsearch/elasticsearch.yml # bootstrap.memory_lock: true [root@es103.yinzhengjie.com ~]# [root@es103.yinzhengjie.com ~]# sed -r -i s'@# (bootstrap.memory_lock: true)@1@' /etc/elasticsearch/elasticsearch.yml [root@es103.yinzhengjie.com ~]# [root@es103.yinzhengjie.com ~]# grep bootstrap.memory_lock /etc/elasticsearch/elasticsearch.yml bootstrap.memory_lock: true #该参数的含义就是将上一步分配的物理内存进行立即分配操作。 [root@es103.yinzhengjie.com ~]#

3>.内存锁不起作用(memory locking requested for elasticsearch process but memory is not locked)解决方案
在Elasticsearch版本低于5.1.x，需要修改启动脚本。需要i修改如下的配置文件: /etc/elasticsearch/elasticsearch.yml bootstrap.memory_lock: true /usr/lib/systemd/system/elasticsearch.service [Service] #在该标签内添加下面一行 LimitMEMLOCK=infinity /etc/sysconfig/elasticsearch(Ubuntu系统可忽略该文件，因为默认并不存在该文件，但需要修改下面的limits.conf文件哟~) MAX_LOCKED_MEMORY=unlimited /etc/security/limits.conf CentOS可以参考以下配置: * soft memlock unlimited * hard memlock unlimited Ubuntu可以参考以下配置(需要写具体的账号，不要使用"*"来代指所有用户，否则会不生效哟~): elasticsearch soft memlock unlimited elasticsearch hard memlock unlimited 博主推荐阅读: https://discuss.elastic.co/t/memory-lock-not-working/70576 https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html
