Ubuntu 12.04与CentOS 6用户管理实战：sudo权限修复与安全增删 Linux用户管理是系统运维的基础能力，其核心在于账户生命周期控制、权限继承机制与安全边界设定。sudo作为提权枢纽，依赖setuid位、/etc/sudoers策略及用户组归属三重保障；一旦失效（如'effective uid is not 0'），将导致整个特权操作链断裂。在老旧系统中，由于内核模块锁定、闭源软件依赖及包源停更，无法通过常规升级修复，必须掌握底层命令差异（useradd vs adduser）、shadow密码字段语义（!!与*）、home目录清理逻辑（-r行为反转）等关键细节。本文聚焦阅读详情

第一次用sudo 安装mysql,用root 去做安转没有什么问题，
现在sudo 安装完以后，无论如何也启动不了mysql,以下是错误信息:
