我在CentOS机器上安装了SonarQube 5.6.6。在运行命令sudo /etc/init.d/sonar start时，我在控制台上收到一条消息，说服务器已启动。但是，我无法通过点击URL访问服务器。它说＆＃34;网页不可用＆＃34;。这是启动服务器后的日志文件：

如果我尝试通过此链接访问服务器页面：http://localhost:9000/sonar，网页不可用，并且在尝试停止时，我收到一条控制台消息：＆＃34; SonarQube未运行＆＃34; 。但是，如果我在点击URL之前尝试停止它，则控制台消息为：＆＃34;停止SonarQube＆＃34;。这似乎很奇怪。
停止服务器后，日志文件的其余部分如下：

这是我在sonar.properties文件中编写的一些属性：
sonar.web.host = 172.31.254.181 sonar.web.context = / sonar sonar.web.port = 9000 sonar.jdbc.username =声纳 sonar.jdbc.password =声纳 ？sonar.jdbc.url = JDBC：MySQL的：//本地主机：3306 /声纳了useUnicode =真安培;的characterEncoding = UTF8＆安培; rewriteBatchedStatements =真安培; useConfigs = maxPerformance
任何帮助整理此问题都将不胜感激。

您的SonarQube服务器实际上无法启动。并且错误就在您共享的日志中：
2017.03.08 03:46:26 ERROR web [o.a.c.c.C。[。[。[/ sonar]]将上下文初始化事件发送到类org.sonar.server.platform.PlatformServletContextListener的侦听器实例的异常 org.sonar.api.utils.MessageException：不支持的mysql版本：5.1。支持的最低版本为5.6。
SonarQube v5.6.x要求为here，而对于MySQL，仅支持版本5.6或5.7（就像日志所述）。
