CentOS 6.9/7通过yum安装指定版本的PostgreSQL扩展PostGIS

一、安装PostGIS扩展插件（24_10）

// 安装EPEL源
# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
// 安装PostGIS
# yum install -y postgis24_10

备注：提示依赖错误需要安装EPEL的源，对应的每个系统不一样，如下所示：

# CentOS 7, RHEL 7 64-bit:
# rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
# CentOS 6, RHEL 6 64-bit:（这里根据自已的系统版本作选择）
# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

提示：还有一些系统的，可以在上级目录找到（http://dl.fedoraproject.org/pub/epel/）。

二、开启PostgreSQL的PostGIS扩展并验证

// 开启插件
# su postgres
# psql
// 开启pgsql的插件
postgres=# create extension postgis;
postgres=# create extension postgis_topology;
postgres=# create extension fuzzystrmatch;
postgres=# create extension address_standardizer;
postgres=# create extension address_standardizer_data_us;
postgres=# create extension postgis_tiger_geocoder;
// 测试验证
-- 创建表
postgres=# create table mytable (
id serial primary key,
geom geometry(point, 26910),
name varchar(128)
);
-- 添加索引
postgres=# create index mytable_gix
on mytable
using gist (geom);
-- 添加一条数据
postgres=# insert into mytable (geom) values (
st_geomfromtext('point(0 0)', 26910)
);
-- 测试查询，正常能查出一条数据
postgres=# select id, name
from mytable
where st_dwithin(
geom,
st_geomfromtext('point(0 0)', 26910),
1000
);
