一、★★★★★★★单机版安装及环境配置★★★★★★★
安装环境 CentOS release 6.7 (Final)
1、因Elasticsearch是基于Java写的,所以它的运行环境中需要java的支持,在Linux下执行命令:
java -version,检查Jar包是否安装
安装java版本至少是1.8以上
2、首先准备下载Elasticsearch5.5.0 安装包
wget https://artifacts.elastic.co/d ... earch
3、下载到/usr/openv 目录下,解压
tar -zxvf elasticsearch-5.5.0.tar.gz
4、因为Elasticsearch5.0之后,不能使用root账户启动,我们先创建一个esuser组和账户
useradd esuser -g esuser -p esuser
5.更改文件夹权限
chown -R esuser:esuser /usr/openv/elasticsearch-5.5.0
6、启动elasticsearch:
/usr/openv/elasticsearch-5.5.0/bin
su esuser
./elasticsearch (前台启动)
这时候我们看见下面的提示,说明就成功了:
1. [elasticsearch@vmlnx-sma bin]$ ./elasticsearch

./elasticsearch -d (后台启动)
执行 curl http://localhost:9200
打开另一个终端进行测试:
curl 'http://localhost:9200/?pretty'
你能看到以下返回信息:
{
"status": 200,
"name": "Shrunken Bones",
"version": {
"number": "1.4.0",
"lucene_version": "4.10"
},
"tagline": "You Know, for Search"
}
说明安装成功。
但是我们希望能够使用ip访问,那么还需要设置相关内容
跳转到Elasticsearch的config配置文件下,使用vim打开elasticsearch.yml,找到里面的"network.host",将其改为本机IP,保存。
cd elasticsearch/config/
vim elasticsearch.yml
重启ElasticSearch,然后使用http://192.168.37.137:9200/访问。
二、★★★★★★★常见错误★★★★★★★
问题一:警告提示
[2016-11-06T16:27:21,712][WARN ][o.e.b.JNANatives ] unable to install syscall filter:
java.lang.UnsupportedOperationException: seccomp unavailable: requires kernel 3.5+ with CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER compiled in
at org.elasticsearch.bootstrap.Seccomp.linuxImpl(Seccomp.java:349) ~[elasticsearch-5.0.0.jar:5.0.0]
at org.elasticsearch.bootstrap.Seccomp.init(Seccomp.java:630) ~[elasticsearch-5.0.0.jar:5.0.0]
报了一大串错误,其实只是一个警告。
解决:使用心得linux版本,就不会出现此类问题了。
问题二:ERROR: bootstrap checks failed
max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
max number of threads [1024] for user [lishang] likely too low, increase to at least [2048]
解决:切换到root用户,编辑limits.conf 添加类似如下内容
vi /etc/security/limits.conf
添加如下内容:
* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096
问题三:max number of threads [1024] for user [lish] likely too low, increase to at least [2048]
解决:切换到root用户,进入limits.d目录下修改配置文件。
vi /etc/security/limits.d/90-nproc.conf
修改如下内容:
* soft nproc 1024
#修改为
* soft nproc 2048
问题四:max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]
解决:切换到root用户修改配置sysctl.conf
vi /etc/sysctl.conf
添加下面配置:
vm.max_map_count=655360
并执行命令:
sysctl -p
然后,重新启动elasticsearch,即可启动成功。
三、★★★★★★★★★★★★★★★★★★★
查看集群健康状态:curl -XGET 'http://localhost:9200/_cluster/health?pretty=true'
查看本地节点信息:curl -XGET http://localhost:9200/
其它一些命令:
查看集群状态:curl -XGET http://localhost:9200/_cat/health?v
curl -XGET 'http://localhost:9200/_cluster/state?pretty'
curl -XGET 'http://localhost:9200/_cluster/stats?human&pretty'
查看集群节点:curl -XGET http://localhost:9200/_cat/nodes?v
curl -XGET 'http://localhost:9200/_nodes/stats?pretty'
curl -XGET 'http://localhost:9200/_nodes/stats/os,process?pretty'
查询索引列表:curl -XGET http://localhost:9200/_cat/indices?v
创建索引:curl -XPUT http://localhost:9200/customer?pretty
查询索引:curl -XGET http://localhost:9200/customer/external/1?pretty
删除索引:curl -XDELETE http://localhost:9200/customer?pretty
停服与重启
停止ES服务器
如果是前台启动,直接Ctrl+Z或者直接关掉命令行窗口,则服务器立即停止。
如果是通过后台启动的ES服务,则需要用如下命令停止服务器:
也可以直接在Window系统的服务列表中找到安装的服务,然后右键停止。
另外,还可以通过curl工具来关掉整个集群或者集群中的指定节点,命令如下:
关掉集群:curl -XPOST http://localhost:9200/-cluster/nodes/_shutdown。
关掉指定的节点,节点标识符为jMJhGirhSRa9Iw2fQtjJ5A:curl -XPOST http://localhost:9200/_cluster ... tdown。
重启ES服务器
如果是想再次重启已经启动的ES服务,可以在Window系统的服务列表中找到安装的服务,然后右键重新启动即可。
