启动Sonar报错，ERROR: [1] bootstrap checks failed [1]: system call filters failed to install

错误提示信息：

ERROR: [1] bootstrap checks failed
[1]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

解决： 
Centos6不支持SecComp，而ES5.2.0默认bootstrap.system_call_filter为true

禁用：在elasticsearch.yml中配置bootstrap.system_call_filter为false，注意要在Memory下面: 
bootstrap.memory_lock: false 
bootstrap.system_call_filter: false

网上大多数解决办法如上，但是实际操作后发现不生效，原因是以上针对老版本sonar,本人使用最新版sonar7.9.

解决办法如下：

1，修改sonar配置 sonar.properties 

sonar.search.javaAdditionalOpts=-Dbootstrap.system_call_filter=false  

2，修改 ../sonar/conf 下wrapper.conf 

wrapper.java.additional.1=-Dsonar.wrapped=true -Dbootstrap.system_call_filter=false

3, 修改../sonar/elasticsearch/config/elasticsearch.yml Memory下面 

bootstrap.memory_lock: false

bootstrap.system_call_filter: false

问题解决，es启动成功
