参考官网 http://postgis.net/

PostGis版本2.5.3

1.安装libxml2

# yum install libxml2 libxml2-devel

2.安装json-c

# tar zxvf json-c-json-c-0.13.1-20180305.tar.gz

# cd json-c-json-c-0.13.1-20180305

# ./configure && make && make install

3.安装protobuf-c

# tar zxvf protobuf-3.9.2.tar.gz

# cd protobuf-3.9.2

# ./autogen.sh

# ./configure && make && make install

# /usr/local/bin/protoc --version

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

# tar zxvf protobuf-c-1.3.2.tar.gz

# cd protobuf-c-1.3.2

# ./configure && make && make install

4.安装proj

# tar zxvf sqlite-autoconf-3290000.tar.gz

# cd sqlite-autoconf-3290000

# ./configure && make && make install

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

# tar zxvf proj-6.2.0.tar.gz

# cd proj-6.2.0

# ./configure && make && make install

5.安装geos

# tar zxvf geos-3.7.2.tar.gz

# cd geos-3.7.2

# ./autogen.sh

# ./configure

# make && make install

6.安装gdal

# tar zxvf gdal-3.0.1.tar.gz

# cd gdal-3.0.1

# ./configure && make && make install

7.安装postgis

# tar zxvf postgis-2.5.3.tar.gz

# cd postgis-2.5.3

# ./configure \

--with-geosconfig=/usr/local/bin/geos-config \

--with-projdir=/usr/local/ \

--with-gdalconfig=/usr/local/bin/gdal-config

# make && make install

确认postgis组间已安装

$ ll /pgdata/postgres/share/extension/postgis*

8.使用postgis

使用超级用户创建扩展

$ psql -Upostgres postgres

create extension postgis;

create extension postgis_topology;

create extension fuzzystrmatch;

create extension postgis_tiger_geocoder;

--测试SQL

CREATE TABLE gtest ( gid serial primary key, name varchar(20));

SELECT AddGeometryColumn ('gtest', 'geom', 4326,'LINESTRING', 2);

select DropGeometryColumn('gtest','geom');

SELECT AddGeometryColumn ('gtest', 'geom', 0,'LINESTRING', 2);

INSERT INTO gtest (GID, NAME, GEOM)

VALUES (1, 'First Geometry',ST_GeomFromText('LINESTRING(2 3,4 5,6 5,7 8)'));

源码编译比较慢，大约需要几个小时不等，如果只是测试使用建议使用docker安装
