这是我转载的一片文章，解决了我的问题，所以记录一下。
话不多说，见正文吧！
elasticsearch安装踩过的那些坑：
坑1:
[***]failed to send join request to master
原因：你复制了某个节点的elasticsearch文件夹，但是这里面包含了该节点的data文件
解决：删除elasticsearch文件夹下data目录的内容
坑2：
ERROR: bootstrap checks failed
memory locking requested for elasticsearch process but memory is not locked
原因：锁定内存失败
解决：vim /etc/security/limits.conf 添加下面两行
- soft memlock unlimited
- hard memlock unlimited
tips:* 代表的是linux内所有的用户
坑3：
ERROR: bootstrap checks failed
max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
原因：无法创建本地文件,用户最大可创建文件数不够
解决：vim /etc/security/limits.conf
原因：无法创建本地线程问题,用户最大可创建线程数太小
解决：vim /etc/security/limits.d/90-nproc.conf
-
soft nproc 2048（这边原本是1024）
坑5：
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
原因：最大虚拟内存太小
解决：vim /etc/sysctl.conf 添加下面这一行
vm.max_map_count=262144
并执行命令：sysctl -p
坑6：
system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
原因：Centos6不支持SecComp
解决：vim elasticsearch.yml 切记在内存锁的下面加
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
坑7：
uncaught exception in thread [main]
org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run elasticsearch as root
原因：elasticsearch不能使用root用户启动
解决：创建新用户（useradd elasticsearch）并 chown -R elasticsearch:elasticsearch elasticsearch-5.2.2 [更改elasticsearch文件夹的用户以及所属组]
坑8：
unable to install syscall filter:

at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:84) [elasticsearch-5.4.0.jar:5.4.0]
原因：linux内核版本太低
解决：凉凉，换个新版本的linux系统吧。
坑9：
Unsupported major.minor version 52.0
原因：java版本太低
解决：更换jdk版本，ElasticSearch5.0.0支持jdk1.8.0以上
坑10：

... 6 more
原因：elasticsearch新版本是不允许安装插件在文件目录plugins下面的
解决：将plugins下面的插件目录放到其他目录即可
