这个错误是因为centos6的内核不支持SecComp，所以我们需要禁止这个功能：

[yutao@master01 config]# vim elasticsearch.yml

Failed to create temporary file for /com/sun/jna/linux-x86-64/libjnidispatch.so library

下面中/home/yutao/tmp/elasticsearch路径被我改过，默认不是这个，但是错都是一样的！

这个错基本是因为访问权限的原因造成的！

其在往tmp文件写入时，发现没有权限！

所以我就自己创建了一个tmp目录，并修改配置，指定好：

[yutao@master01 config]# vim jvm.options
# 上面省略。。。
# 在最后添加
-Djava.io.tmpdir=/home/yutao/tmp/elasticsearch
-Djna.tmpdir=/home/yutao/tmp/elasticsearch

我知道是权限问题，但是明明elasticsearch能正常启动，安装插件居然报错，
其实上面写修改elasticsearch启动脚本，还不如修改elasticsearch-env这个文件，这里是elasticsearch环境变量文件，修改方式和之前一样。

对于这个问题，我就是重新登录下CRT，就好了。

==============2017年12月2日 23点32分===========
特意记录下，上面我写到，重新登录下就好了，其实是因为重新登录后，我的登录用户变成了root，自然有权限往/tmp目录里写东西啦！

而当我以yutao用户登录，安装时，就会报没有权限，也就是上面这个错误；

我没有找到好的办法，我把/tmp的权限改为777，就可以安装啦！

但是我觉得 ，能指定这个路径才是最优的做法；

我在elastic中文社区提出了这个问题，知道的帮忙回答下谢谢：
https://elasticsearch.cn/question/2996

WWW-Authenticate”:”Basic realm=\”security\” charset=\”UTF-8\”

{"error":{"root_cause":[{"type":"security_exception","reason":"Failed to authenticate user [elastic]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}}],"type":"security_exception","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}},"status":401}

输入默认用户和密码，就报这个错，猜想就是用户名和密码不对，虽然不明白为什么会不对，后来我执行下面命令重新生成密码：

[yutao@master01 elasticsearch-6.0.0]$ bin/x-pack/setup-passwords auto
Initiating the setup of reserved user elastic,kibana,logstash_system passwords.
The passwords will be randomly generated and printed to the console.
Please confirm that you would like to continue [y/N]y


Changed password for user kibana
PASSWORD kibana = WjFJ6G$lEH71W7K1+vcl

Changed password for user logstash_system
PASSWORD logstash_system = TS8ZR41smxm9o?F6gbBB

Changed password for user elastic
PASSWORD elastic = rc~ENBxy?18hOQ^R9OUJ

[yutao@master01 elasticsearch-6.0.0]$

Can not upgrade to a production license unless TLS is configured or security is disabled

{"error":{"root_cause":[{"type":"illegal_state_exception","reason":"Can not upgrade to a production license unless TLS is configured or security is disabled"}],"type":"illegal_state_exception","reason":"Can not upgrade to a production license unless TLS is configured or security is disabled"},"status":500}

这个错误，是因为elasticsearch6.0.0，现在更新license文件时，要么配置SSL\TLS，要么就禁用security。

那就临时禁用，更新完了再启用就行了：

[yutao@master01 elasticsearch-6.0.0]$ vim config/elasticsearch.yml
# 以上省略。。。
xpack.security.enabled: false
#xpack.security.transport.ssl.enabled: true

更新完了license后，再改为：

xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

bootstrap checks Failed

ERROR: [1] bootstrap checks Failed
[1]: Transport SSL must be enabled for setups with production licenses. Please set [xpack.security.transport.ssl.enabled] to [true] or disable security by setting [xpack.security.enabled] to [false]
[2017-12-02T23:30:06,538][INFO ][o.e.n.Node ] [FWGb82W] stopping ...

[2017-12-02T23:30:06,610][INFO ][o.e.n.Node ] [FWGb82W] closed

这是因为更新license并启动xpack.security.enabled: true，后必须也要启用xpack.security.transport.ssl.enabled: true；

小技巧

因为elasticsearch不能使用root用户登录，而我一般都是使用root登录CRT的，所以可以使用：

su yutao

临时切下身份，可以使用ctrl + D，再切换回来。
