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  
\*                hard    nofile          65536  
\*                soft    nofile          65536  
\*                soft    nproc           65536  
\*                hard    nproc           65536

坑4：  
max number of threads \[1024\] for user \[es\] is too low, increase to at least \[2048\]  
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:  
java.lang.UnsupportedOperationException: seccomp unavailable: requires kernel 3.5+ with CONFIG\_SECCOMP and CONFIG\_SECCOMP\_FILTER compiled in

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以坑10：*org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: Property \[elasticsearch.version\] is missing for plugin \[head\]*

        ... 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
