note The full stack trace of the root cause is available in the Apache Tomcat/7.0.76 logs.
Apache Tomcat/7.0.76摸索
翻遍了各种搜索引擎，就没遇到过说权限不够的
1 修改服务运行用户为root
没效果
2 给tomcat所有相关的目录授权
没效果
3 修改tomcat配置文件，注入jvm参数
没效果
解决
也不算是解决了，是放弃了
原来 tomcat 是用 yum 安装的
换成官方的安装包，或编译安装都可以，就没有权限问题了
到最后我也没搞清楚啥原因，有时间了在继续研究
记得添加tomcat运行用户
groupadd tomcat
useradd -g tomcat -s /usr/sbin/nologin tomcat最后
以上就是自信狗为你收集整理的redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: 权限不够的全部内容，希望文章能够帮你解决redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: 权限不够所遇到的程序开发问题。
