Ensure a Dedicated Least-Privilege Account Is Used for TDSQL Processes

高级别 1自动化tdsql

说明

Each TDSQL component (OSS, Manager/Scheduler/Keeper, Agent, MySQL) should run under a dedicated, non-root, least-privilege operating system account. The MySQL daemon should not run as root. TDSQL management processes should run under a dedicated account (e.g., tdsql). Counts mysqld, oss_server, scheduler and ZooKeeper processes running as root (FAIL when none of these processes is running).

检查方式

审计方法: Shell 命令

shell

out=$(ps -eo user=,comm=,args= 2>/dev/null) || exit 1; printf '%s\n' "$out" | awk '$2 ~ /^(mysqld|mysqld_safe|oss_server|scheduler)$/ || ($2 == "java" && /zookeeper/) {n++; if ($1 == "root") r++} END {if (n == 0) exit 1; print r + 0}'

预期输出: 0

修复方式

修复方法: 操作指南或基础设施补丁

Create a dedicated system account (groupadd -r tdsql; useradd -r -g tdsql -s /sbin/nologin -d /data/tdsql tdsql), chown the TDSQL directories to it and restart each component under that account.
