Sonarqube 6.7.4 can not start on CoentOS7

I install sonarqube 6.7.4, and I start it as sonar which is created by root ,and this user has all privileges.

This is my web.log below, and it present some error
[o.e.t.n.Netty4Transport] write and flush on the network layer failed (channel: [id: 0xfac2a38f, L: ! R:/]

Someone can help me? Thanks in advance


Welcome to the community!

Why would you do that? SonarQube 6.7 is ~3.5y old & far past EOL. SonarQube 8.9 was released last week and is the current LTS. Why not give it a try?
