Ensure Appropriate System Resource Limits Are Configured

中等級 1自動化tdsql

說明

Operating system resource limits (ulimits) should be properly configured for TDSQL processes, particularly the number of open file descriptors, maximum processes, and memory locking. Passes when /etc/security/limits.conf or limits.d sets hard nofile and nproc limits of at least 65535 for the tdsql user (the benchmark baseline). For systemd-managed components also confirm LimitNOFILE/LimitNPROC in the unit.

檢查方式

稽核方法: Shell 指令

shell

out=$(cat /etc/security/limits.conf /etc/security/limits.d/*.conf 2>/dev/null) || exit 1; printf '%s\n' "$out" | awk '$1 == "tdsql" && $2 == "hard" && $3 == "nofile" && ($4 == "unlimited" || $4 + 0 >= 65535) {f++} $1 == "tdsql" && $2 == "hard" && $3 == "nproc" && ($4 == "unlimited" || $4 + 0 >= 65535) {p++} END {print (f && p) ? "compliant" : "noncompliant"}'

預期輸出: compliant

修補方式

修補方法: 操作指南或基礎設施修補檔

Add to /etc/security/limits.conf: tdsql soft nofile 65535; tdsql hard nofile 65535; tdsql soft nproc 65535; tdsql hard nproc 65535; tdsql soft memlock unlimited; tdsql hard memlock unlimited; then restart the components.
