Linux Mint(or ubuntu) 快速安裝 postgresql 9.3


安裝 postgresql 9.3 伺服器程式
mt ~ # apt-get install postgresql-9.3

安裝 pgadmin3 的客戶端管理工具
mt ~ # apt-get install pgadmin3

切換到 postgres 帳號, postgres 預設沒有密碼且是 superuser 權限
mt ~ # su - postgres
postgres@mt ~ $ ls
9.3
postgres@mt ~ $ pwd
/var/lib/postgresql

建立使用者帳號,-r 能夠建立 role ,並且賦予  -s 超級使用者、-d 能夠建立 DB 、-l 能夠登入系統、-P能夠建立密碼
postgres@mt ~ $ createuser --r mtchang -s -d -l  -P
Enter password for new role:
Enter it again: 

建立一個資料庫 mtchang 屬於 -O mtchang 使用者的
postgres@mt ~ $ createdb  -O mtchang mtchang

設定 PGADMINIII 客戶端工具






以上為本機使用 postgresql 的安裝方式,如果還要讓外面的 IP 可以連到這台請參考這篇:
