Ingredients：
-
Java：Java SE Development Kit 8u162(Oracle Java Archive)，Linux下安装JDK并修改环境变量
-
Elasticsearch：elasticsearch-6.6.2.tar.gz，(Elasticsearch version 6.6.2，Download Elasticsearch，Past Releases)
1 下载
创建文件夹：
mkdir -p /opt/elasticsearch/
进入文件夹：
cd /opt/elasticsearch/
下载elasticsearch-6.6.2.tar.gz版本：
curl -c https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.6.2.tar.gz
2 解压缩
tar -zxvf elasticsearch-6.6.2.tar.gz
进入解压后的文件夹：
cd /opt/elasticsearch/elasticsearch-6.6.2/
3 启动
启动：
./elasticsearch
3.1 错误1：不能使用root用户
报错：
[root@shizhi002 bin]# ./elasticsearch

解决办法：
[root@shizhi002 bin]# useradd es
[root@shizhi002 bin]# chown -R es:es /opt/elasticsearch/elasticsearch-6.6.2
[root@shizhi002 bin]# su es
[es@shizhi002 bin]$ ./elasticsearch
3.2 错误2：文具描述符不够，虚拟内存不够
[2019-03-21T11:23:56,092][INFO ][o.e.b.BootstrapChecks ] [T92Oci_] bound or publishing to a non-loopback address, enforcing bootstrap checks
ERROR: [2] bootstrap checks failed
[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]

这里面有2个错误：
- 1：文件描述符太少：
[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]
解决办法是编辑文件：
vi /etc/security/limits.conf
将原有的：
* hard nofile 65535
修改为：
* hard nofile 65536
配置完需重新启动服务器。
- 2：虚拟内存太少
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决办法是编辑文件：
vi /etc/sysctl.conf
加入内容：
vm.max_map_count=262144
配置完需重新启动服务器。
3.3 错误3：日志操作权限不够

错误原因：有可能你先使用了root用户启动，发现不可以又换成了es用户，这时候其实log日志已经被root用户生成了，权限也为root，这时候就需要再次参考错误1设置权限：
chown -R es:es /opt/elasticsearch/elasticsearch-6.6.2
4 再次启动
再启动就成功了：
