es不能用root启动，所以创建用户es

#添加用户
    adduser es
    #设置密码
    passwd es
    ---------------
    #授权，root用户下
    chmod -v u+w /etc/sudoers
    #编辑
    vim /etc/sudoers
    #文件中插入，在root用户的下面（NOPASSWD:ALL，使用sudo时不用输密码）
    es      ALL=(ALL)       NOPASSWD:ALL
    #收回权限
    chmod -v u-w /etc/sudoers
    ---------------
    #添加分组
    groupadd testgroup
    usermod -G testgroup es
    #修改es目录的访问权限
    chown -R es:testgroup *

授权：
    chown -R es:es /usr/local/elasticsearch-7.3.2

修改配置：
    vi /etc/security/limits.conf
    文末增加：

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

![1628476-20190918230338967-7693966.png][]

cd /etc/security/limits.d/
    vim 20-nproc.conf 
    （*改成用户名es，如图）

![1628476-20190918230523054-1083783555.png][]

vi /etc/sysctl.conf
    增加：
    vm.max_map_count = 655360

![1628476-20190918230640823-1278784156.png][]

使其生效 
    sysctl -p

![1628476-20190918230807440-1842251579.png][]

切换到es用户，启动es
     su es

启动
     /usr/local/elasticsearch-7.3.2/bin/elasticsearch

![1628476-20190918230922202-368981436.png][]

![1628476-20190918230938117-1309938126.png][]

配置完成，访问出现下面内容，则启动正常：

127.0.0.1:9200

安装es后，不能直观的查看es中的数据，我们可以安装head插件，window方法：[https://blog.csdn.net/weixin\_41575259/article/details/82531276][https_blog.csdn.net_weixin_41575259_article_details_82531276]
