参考：sonarqube环境搭建采坑详解_HenryXiao的博客-CSDN博客 （感谢分享）
补充：参考后仍有些小问题，记录一下
1.es内存不足：问题翻译过来就是：elasticsearch用户拥有的内存权限太小，至少需要262144
ERROR: [1] bootstrap checks failed
[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决：
切换到root用户修改配置sysctl.conf
vi /etc/sysctl.conf
添加下面配置：
vm.max_map_count=655360
并执行命令：
sysctl -p
2.mysql ssl配置，注意sonar.jdbc.url项useSSL=false可暂时解决
Tue Oct 12 14:49:08 CST 2021 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
