### 注意：已非root用户操作一下操作，切记  切记  切记 ###

### 1、官网下载ElasticSearch7.2 ###

打开官⽹链接 https://www.elastic.co/guide/en/elastic-stack/7.2/index.html

选择你要下载的版本

###       下载完成之后，解压到自己想放的路径下 ###

### 2、JDK环境配置。。。省略 ###

注意：ElasticSearch对jdk版本要求很严格，我用的jdk11对应ES7.2

### 3、修改配置文件：/opt/es/elasticsearch-7.2.0/config/elasticsearch.yml    ###

network.host: 192.168.164.26
    http.port: 9200

### 4、启动 ###

查看所有用户：compgen -u

创建用户：useradd es

创建密码：passwd es

切换用户到es：sudo su 或者 su   --》 su es

进入到|/opt/es/elasticsearch-7.2.0/bin/，

启动命令：./elasticsearch

后台运行：./elasticsearch -d

或者守护进程的方式可以使用sh elasticsearch.sh -d -p pid

# 启动问题处理： #

ERROR: [5] bootstrap checks failed
    [1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
    [2]: memory locking requested for elasticsearch process but memory is not locked
    [3]: max number of threads [1024] for user [wangxiang] is too low, increase to at least [4096]
    [4]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
    [5]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

### 1.修改vi /etc/security/limits.conf文件，增加配置 ###

*               soft    nofile          65536
    *               hard    nofile          65536

### 2.  切换到root用户，编辑vi /etc/security/limits.conf配置文件，添加如下内容:  ###

* soft memlock unlimited 
    * hard memlock unlimited

备注：\* 代表Linux所有用户名称

### 3. 最大线程个数太低。修改配置文件 vi /etc/security/limits.d/90-nproc.conf ###

*               soft    nproc           4096
    *               hard    nproc           4096

### 4. 修改/etc/sysctl.conf文件，增加配置 ###

vm.max_map_count=262144
    或者
    vm.max_map_count=655360

执行命令sysctl -p生效

### 5. 在elasticsearch.yml中添加配置项 ###

bootstrap.memory_lock: false
    bootstrap.system_call_filter: false

### 6、在elasticsearch.yml中修改配置项 ###

node.name: node-1
    cluster.initial_master_nodes: ["node-1"]

### 保存重启后访问 ###
