ElasticSearch-6.5.3系列 安装篇一

准备资料：JDK ElasticSearch-6.5.3 Kibana Logstash

链接：https://pan.baidu.com/s/1TMpMvXjMvUbpVnpfBIJDXA 
提取码：e1jz 
安装环境：CentOS 7.3

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.5.3.tar.gz
wget https://artifacts.elastic.co/downloads/kibana/kibana-6.5.3-linux-x86_64.tar.gz
wget https://artifacts.elastic.co/downloads/logstash/logstash-6.5.3.tar.gz

第一步：创建账号

[root@izwz99z5o9dc90keftqhlrz ~]# useradd es
[root@izwz99z5o9dc90keftqhlrz ~]# passwd es
123456
123456

第二步：安装JDK

[root@izwz99z5o9dc90keftqhlrz ~]# tar -zxvf jdk-8u172-linux-x64.tar.gz -C /usr/local

配置环境变量，记得我们JDK使用root账户安装，免得后面总是提示没有权限:

[root@izwz99z5o9dc90keftqhlrz install]# vi /etc/profile


#加到最后面

PATH=$PATH:$HOME/bin

export JAVA_HOME=/usr/local/jdk1.8.0_172
export JRE_HOME=${JAVA_HOME}/jre

export PATH=$JAVA_HOME/bin:$PATH

export PATH

使环境变量立即生效： 

[root@izwz99z5o9dc90keftqhlrz install]# source /etc/profile

测试一下：

[root@izwz99z5o9dc90keftqhlrz install]# echo $JAVA_HOME
/usr/local/jdk1.8.0_172

第三步：配置系统参数

vi /etc/sysctl.conf

在文件最后面添加内容:
vm.max_map_count=262144

保存后，执行
sysctl -p

vi /etc/security/limits.conf

添加如下内容:
* hard nofile 65536
* soft nofile 65536

* soft nproc 2048
* hard nproc 4096

第四步：安装Elastic

这时我们使用es账户登录，操作

开始安装：

[es@izwz99z5o9dc90keftqhlrz ~]$ tar -zxvf elasticsearch-6.5.3.tar-1.gz 

配置：

修改内容(没有就添加):
cluster.name: es-wuneng
node.name: node-1
network.host: 0.0.0.0 
http.port: 9200
bootstrap.memory_lock: false
bootstrap.system_call_filter: false

测试运行：

进入Elasticsearch的bin目录 
控制台 测试使用
[es@izwz99z5o9dc90keftqhlrz bin]$ ./elasticsearch

后台运行 生产使用
[es@izwz99z5o9dc90keftqhlrz bin]$ ./elasticsearch -d

运行成功的代码：

第五：安装错误处理

错误：
 in 'reader', line 17, column 1:
    cluster.name: es-xing
    ^
expected <block end>, but found Scalar
 in 'reader', line 51, column 2:
     -------------------------------- ... 
     ^

    cluster.name: es-xing
    ^

     -------------------------------- ... 

解决：加个空格就好了，每个选项 - 非常坑
这是说配置文件的问题：config/elasticsearch.yml
#
 network.host: 0.0.0.0
#
# Set a custom port for HTTP:
#
 http.port: 9200

问题：
ERROR: [1] bootstrap checks failed
[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]
[2019-10-23T22:11:00,102][INFO ][o.e.n.Node               ] [node-1] stopping ...

[2019-10-23T22:11:00,160][INFO ][o.e.n.Node               ] [node-1] closed

解决：root账户
vim /etc/security/limits.conf
# End of file
root soft nofile 65536
root hard nofile 65536
* soft nofile 65536
* hard nofile 65536

* soft nproc 2048
* hard nproc 4096

要改到：65536
然后用es再登录操作，原来那个窗口可能获取不到新参数

问题：内存不足
[2019-10-23T22:20:49,428][INFO ][o.e.d.DiscoveryModule    ] [node-1] using discovery type [zen] and host providers [settings]

启动内存改小点：
[es@izwz99z5o9dc90keftqhlrz elasticsearch-6.5.3]$ vi config/jvm.options 

#-Xms1g
#-Xmx1g

-Xms700m
-Xmx700m
