You must address the points described in the following [2] lines before starting Elasticsearch.bootstrap check failure [1] of [2]: max number of threads [3870] for user[sonar] istoo low，increase to at least [4096]bootstrap check failure [2] of [2]: max virtual memory areas vm.max map count [65530is too low，increase to at least [262144]ERROR: Elasticsearch did not exit normally- check the logs at /usr/local/sonarqube-90.0.45539/logs/sonarqube.logapp[]

解決如下：

修改/etc/sysctl.conf文件，文件末尾追加vm.max_map_count=262144

修改/etc/security/limits.conf文件，文件末尾追加

* soft nproc 4096* hard nproc 4096* soft nofile 1000000* hard nofile 1000000

然后重啟虛擬機，再次啟動sonar
