问题一：

INFO  app[][o.s.a.ProcessLauncherImpl] Launch process[[key='es', ipcIndex=1, logFilenamePrefix=es]] from [/opt/sonarqube/elasticsearch]: /opt/sonarqube/elasticsearch/bin/elasticsearch
could not find java in ES_JAVA_HOME at /opt/java/openjdk/bin/java

解决方案：

出现此问题的原因是权限不足，需要以root权限启动
docker-compose.yml 文件里添加 ：
privileged: true

问题二：

ERROR:[1] bootstrap checks failed.You must address the points described in the following [1]lines before starting Elasticsearchbootstrap check failure [1] of [1]: max virtual memory areas vm.max map_count [65530] is too liow， increase to at least [262144]
EROR:Elasticsearch did not exit normally - check the logs at /opt/sonarqube/logs/sonarqube.log

解决方案

在宿主机上修改

vim  /etc/sysctl.conf
#在底部插入
vm.max_map_count=262144
#保存后执行以下命令生效
sysctl -p
