一、數據庫搭建
1、yum 指定目錄安裝

2、yum 直接安裝
https://blog.csdn.net/llwy1428/article/details/102486414
3、編譯安裝

4、PostgreSql 基本操作
https://blog.csdn.net/llwy1428/article/details/102598732
二、擴展安裝
1、下載 epel-7.repo
[root@pgadmin ~]# cd /etc/yum.repos.d/
[root@pgadmin yum.repos.d]# wget https://mirrors.aliyun.com/repo/epel-7.repo
2、安裝工具
[root@localhost ~]# yum install pgagent_11 postgis25_11 -y
3、查看當前服務器可用的 Extension 擴展列表
# 切換用戶
[root@localhost ~]# su - postgres
Last login: Mon Mar 16 21:15:46 CST 2020 on pts/3
# 進入 postgresql 命令行
[postgres@localhost ~]$ psql
psql (11.5)
Type "help" for help.
postgres=# select name from pg_available_extensions;
name
------------------------------
insert_username
dict_int
adminpack
amcheck
intagg
autoinc
intarray
bloom
file_fdw
dblink
btree_gin
fuzzystrmatch
seg
btree_gist
jsonb_plperl
hstore
citext
isn
jsonb_plperlu
cube
hstore_plperl
dict_xsyn
hstore_plperlu
earthdistance
lo
ltree
pg_trgm
tcn
moddatetime
pageinspect
pg_visibility
pgstattuple
postgres_fdw
pg_buffercache
xml2
pg_freespacemap
refint
sslinfo
tablefunc
pg_prewarm
pgcrypto
pg_stat_statements
pgrowlocks
timetravel
tsm_system_rows
address_standardizer
tsm_system_time
unaccent
address_standardizer_data_us
uuid-ossp
postgis
postgis_sfcgal
postgis_tiger_geocoder
postgis_topology
plpgsql
(55 rows)
4、查看當前數據庫列表
postgres=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+----------+----------+-------------+-------------+-----------------------
postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
(3 rows)
5、在默認數據庫中安裝 pgagent 擴展
postgres=# create extension pgagent;
CREATE EXTENSION
安裝擴展成功
服務啓動、關閉、設置開機啓動
服務啓動
[root@localhost ~]# systemctl start pgagent_11
服務停止
[root@localhost ~]# systemctl stop pgagent_11
服務當前狀態查看
[root@localhost ~]# systemctl status pgagent_11
服務開機啓動
[root@localhost ~]# systemctl enable pgagent_11
禁止服務開機啓動
[root@localhost ~]# systemctl disable pgagent_11
6、在指定數據庫中 安裝擴展
(1)創建測試數據庫,並查看列表
postgres=# create database pgtest;
CREATE DATABASE
postgres=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+----------+----------+-------------+-------------+-----------------------
pgtest | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
(4 rows)
(2)切換數據庫
postgres=# \c pgtest
You are now connected to database "pgtest" as user "postgres".
pgtest=#
(3)安裝擴展 postgis
pgtest=# create extension "uuid-ossp";
CREATE EXTENSION
(4)安裝擴展 uuid-ossp
pgtest=# create extension postgis;
CREATE EXTENSION
(5)安裝擴展 ltree
pgtest=# create extension "ltree";
CREATE EXTENSION
(6)安裝擴展 timetravel
pgtest=# create extension "timetravel";
CREATE EXTENSION
其他擴展:略。
(7)查看當前已安裝的擴展
pgtest=# \dx
List of installed extensions
Name | Version | Schema | Description
------------+---------+------------+---------------------------------------------------------------------
ltree | 1.1 | public | data type for hierarchical tree-like structures
plpgsql | 1.0 | pg_catalog | PL/pgSQL procedural language
postgis | 2.5.3 | public | PostGIS geometry, geography, and raster spatial types and functions
timetravel | 1.0 | public | functions for implementing time travel
uuid-ossp | 1.1 | public | generate universally unique identifiers (UUIDs)
(5 rows)
(8)刪除Extension擴展,查看結果
pgtest=# drop extension timetravel;
DROP EXTENSION
pgtest=# \dx
List of installed extensions
Name | Version | Schema | Description
-----------+---------+------------+---------------------------------------------------------------------
ltree | 1.1 | public | data type for hierarchical tree-like structures
plpgsql | 1.0 | pg_catalog | PL/pgSQL procedural language
postgis | 2.5.3 | public | PostGIS geometry, geography, and raster spatial types and functions
uuid-ossp | 1.1 | public | generate universally unique identifiers (UUIDs)
(4 rows)
至此,Centos7 PostgreSql 數據庫安裝插件基本操作完畢!
希望能夠對您有所幫助!
