2: 初始化數據庫: initdb --locale=C -E UTF-8 /opt/homebrew/var/postgres

chirs@ChrisdeMacBook-Pro ~ % initdb --locale=C -E UTF-8 /opt/homebrew/var/postgres The files belonging to this database system will be owned by user "chirs". This user must also own the server process.The database cluster will be initialized with locale "C". The default text search configuration will be set to "english".Data page checksums are disabled.initdb: error: directory "/opt/homebrew/var/postgres" exists but is not empty If you want to create a new database system, either remove or empty the directory "/opt/homebrew/var/postgres" or run initdb with an argument other than "/opt/homebrew/var/postgres".

3:如果有報錯信息: initdb: error: directory “/opt/homebrew/var/postgres” exists but is not empty， 刪除文件 rm -rf /opt/homebrew/var/postgres

chirs@ChrisdeMacBook-Pro ~ % rm -rf /opt/homebrew/var/postgres chirs@ChrisdeMacBook-Pro ~ % initdb --locale=C -E UTF-8 /opt/homebrew/var/postgres The files belonging to this database system will be owned by user "chirs". This user must also own the server process.The database cluster will be initialized with locale "C". The default text search configuration will be set to "english".Data page checksums are disabled.creating directory /opt/homebrew/var/postgres ... ok creating subdirectories ... ok selecting dynamic shared memory implementation ... posix selecting default max_connections ... 100 selecting default shared_buffers ... 128MB selecting default time zone ...

You can now start the database server using:pg_ctl -D /opt/homebrew/var/postgres -l logfile start

4: 啟動服務: pg_ctl -D /opt/homebrew/var/postgres -l logfile start

chirs@ChrisdeMacBook-Pro ~ % pg_ctl -D /opt/homebrew/var/postgres -l logfile start waiting for server to start.... done server started

5: 創建一個數據庫用戶: createuser username -P

chirs@ChrisdeMacBook-Pro ~ % pg_ctl -D /opt/homebrew/var/postgres -l logfile start waiting for server to start.... done server started chirs@ChrisdeMacBook-Pro ~ % createuser username -P Enter password for new role: Enter it again:

6: 創建一個數據庫: createdb dbname -O username -E UTF8 -e

chirs@ChrisdeMacBook-Pro ~ % createdb dbname -O username -E UTF8 -e SELECT pg_catalog.set_config('search_path', '', false); CREATE DATABASE dbname OWNER username ENCODING 'UTF8';

7: 登入: psql -U username -d dbname
