Ensure Data Cluster Initialized Successfully

高等級 1自動化postgres

說明

First-time installs of a given PostgreSQL major release require the instantiation of the database cluster. A database cluster is a collection of databases that are managed by a single server instance. Checks that data_directory holds an initialized cluster (PG_VERSION) owned by postgres with mode 0700 or 0750; run on the database host. Runs psql as ${PGUSER:-postgres} against ${PGDATABASE:-postgres}; set PGHOST/PGPORT and use ~/.pgpass (not PGPASSWORD, see 1.6/1.7) when peer authentication is not available.

檢查方式

稽核方法: Shell 指令

shell

d=$(psql -X -U "${PGUSER:-postgres}" -d "${PGDATABASE:-postgres}" -tAc "SHOW data_directory" 2>/dev/null) || exit 1; [ -f "$d/PG_VERSION" ] || { echo "no PG_VERSION in $d"; exit 0; }; s=$(stat -c '%a %U' "$d" 2>/dev/null) || exit 1; case "$s" in "700 postgres"|"750 postgres") echo compliant ;; *) echo "$s" ;; esac

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

Initialize the cluster with checksums (PGSETUP_INITDB_OPTIONS="-k" postgresql-18-setup initdb, or initdb -k) and ensure the data directory is owned by postgres with mode 0700 (0750 with group access): chown postgres:postgres <data_directory>; chmod 0700 <data_directory>.
