前一段时间记录了下如何在centos7中离线安装postgresql，因为工作需要，我不仅要安装postgresql，还需要安装postgis插件，这篇文章记录下postgis插件的安装过程。
1. 安装前的参考
如下的链接都是官网上的链接，对你安装postgis 应该会有很大的帮助，安装前可以先仔细看看；
- https://trac.osgeo.org/postgis/wiki/UsersWikiPostgreSQLPostGIS 最新版依赖及下载地址
- https://trac.osgeo.org/postgis/wiki/PostGISObsoleteVersionsMatrix 版本依赖说明
- https://trac.osgeo.org/postgis/wiki/UsersWikiInstall 安装指引
- https://trac.osgeo.org/postgis/wiki
2. 我安装的版本
由于工作需要，我安装的版本与我们线上保持一致，pg安装的是11.11，postgis安装的是2.5，其它详细信息如下：
| 软件 | 依赖 | 版本 |
|---|---|---|
| postgresql | 11.11 | |
| postgis | 2.5 | |
| godal | 2.2.3 | |
| proj | 4.8.0 | |
| geos | 3.5.1 | |
| json-c | 0.10 | |
| protobuf | 2.6.1 | |
| protobuf-c | 1.2.1 | |
| LibXML2 | 2.7.7 |
3.安装依赖
安装postgis共分成两步，第一步是安装依赖，第二步是安装postgis本身，因为postgis需要的依赖比较多，一个一个安装需要有点儿耐心。
注意，如下目录需要修改成你自己使用的目录
3.1 安装gdal
tar -zxvf gdal-2.2.3.tar.gz
cd gdal-2.2.3
./configure --prefix=/app/address/postgre/postgis_dep/gdal
make
make install
3.2 安装proj
tar -zxvf proj-4.8.0.tar.gz
cd proj-4.8.0
./configure --prefix=/app/address/postgre/postgis_dep/proj
make
make install
3.3 安装geos
tar -jxvf geos-3.5.1.tar.bz2
cd geos-3.5.1
./configure --prefix=/app/address/postgre/postgis_dep/geos
make
make install
3.4 安装 json-c
tar -zxvf json-c-0.10.tar.gz
cd json-c-0.10
./configure --prefix=/app/address/postgre/postgis_dep/json-c
make
make install
3.5 安装protobuf
tar -zxvf protobuf-2.6.1.tar.gz
cd protobuf-2.6.1
./configure --prefix=/app/address/postgre/postgis_dep/protobuf
make
make install
3.6 安装 protobuf-c
tar -zxvf protobuf-c-1.2.1.tar.gz
cd protobuf-c-1.2.1
./configure --prefix=/app/address/postgre/postgis_dep/protobuf-c
make
make install
3.7 安装LibXML2
下载地址 http://xmlsoft.org/sources/
tar -zxvf libxml2-2.7.7.tar.gz
cd libxml2-2.7.7
./configure --prefix=/app/address/postgre/postgis_dep/libxml2
make
make install
3.8 编辑 ld.so.conf
增加如下配置
/app/address/postgre/postgis_dep/geos/lib
/app/address/postgre/postgis_dep/gdal/lib
/app/address/postgre/postgis_dep/proj/lib
/app/address/postgre/postgis_dep/json-c/lib
/app/address/postgre/postgis_dep/protobuf/lib
/app/address/postgre/postgis_dep/protobuf-c/lib
/app/address/postgre/postgis_dep/libxml2/lib执行sudo ldconfig 使生效
3.9 修改环境配置文件
修改 vi ~/.bashrc
增加如下配置
export PKG_CONFIG_PATH=/app/address/postgre/postgis_dep/protobuf/lib/pkgconfigexport LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/app/address/postgre/postgis_dep/geos/lib:/app/address/postgre/postgis_dep/gdal/lib:/app/address/postgre/postgis_dep/proj/lib:/app/address/postgre/postgis_dep/json-c/lib:/app/address/postgre/postgis_dep/protobuf/lib:/app/address/postgre/postgis_dep/protobuf-c/lib:/app/address/postgre/postgis_dep/libxml2/lib
source ~/.bashrc 使生效
4. 安装postgis
4.1 安装postgis
tar -zxvf postgis-2.5.0.tar.gz
cd postgis-2.5.0
./configure --with-geosconfig=/app/address/postgre/postgis_dep/geos/bin/geos-config --with-projdir=/app/address/postgre/postgis_dep/proj --with-gdalconfig=/app/address/postgre/postgis_dep/gdal/bin/gdal-config --with-jsondir=/app/address/postgre/postgis_dep/json-c --with-pgconfig=/app/address/postgre/pginstall/bin//pg_config --with-xml2config=/app/address/postgre/postgis_dep/libxml2/bin/xml2-config
make
make install
4.2 登录数据库，创建扩展
psql postgres
创建扩展
create extension postgis;
create extension postgis_topology;
4.3 测试
select postgis_full_version();
SELECT ST_SetSRID(ST_Point(-87.71,43.741),4326),ST_GeomFromText(‘POINT(-87.71 43.741)’,4326);
5. 错误解决
-
fatal error: json_object_iterator.h: No such file or director
解决：yum install json-c-devel -
error: #pragma GCC diagnostic not allowed inside functions
使用高版本gcc，4.4.7不行，我用的是4.8版本

当然在安装postgis之前需要安装postgresql，如果你还没有安装，可以参考我另一篇记录: centos7 离线安装postgresql
