[root@Darren2 proj-4.8.0]# ./configure --prefix=/usr/local/pgsql/plugin/proj

[root@Darren2 proj-4.8.0]# make && make install

Waiting for about 1min

#配置和加載動態鏈接庫：

[root@Darren2 proj-4.8.0]# vim /etc/ld.so.conf.d/proj-4.8.0.conf

/usr/local/pgsql/plugin/proj/lib

[root@Darren2 proj-4.8.0]# ldconfig

安裝geos

[root@Darren2 tools]# wget http://download.osgeo.org/geos/geos-3.4.2.tar.bz2

[root@Darren2 tools]# bzip2 -d geos-3.4.2.tar.bz2

[root@Darren2 tools]# tar xf geos-3.4.2.tar

[root@Darren2 geos-3.4.2]# ./configure --prefix=/usr/local/pgsql/plugin/geos

......

Swig: false

Python bindings: false

Ruby bindings: false

PHP bindings: false

#這些可忽略

[root@Darren2 geos-3.4.2]# make && make install

Waiting for about 5min

#配置和加載動態鏈接庫：

[root@Darren2 geos-3.4.2]# vim /etc/ld.so.conf.d/geos-3.4.2.conf

/usr/local/pgsql/plugin/geos/lib

安裝PostGIS

[root@Darren2 tools]# wget http://download.osgeo.org/postgis/source/postgis-2.1.8.tar.gz

[root@Darren2 tools]# tar xf postgis-2.1.8.tar.gz

./configure --help參數：

  --prefix=PREFIX         install architecture-independent files in PREFIX [/usr/local]

  --with-pgconfig=FILE    specify an alternative pg_config file

  --with-geosconfig=FILE  specify an alternative geos-config file

  --with-projdir=PATH     specify the PROJ.4 installation directory

  --without-raster        Disable the raster extension

[root@Darren2 postgis-2.1.8]# ./configure --prefix=/usr/local/pgsql/plugin/postgis \

--with-pgconfig=/usr/local/pgsql/bin/pg_config \

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

--with-gdalconfig=/usr/local/pgsql/plugin/gdal/bin/gdal-config \

--with-projdir=/usr/local/pgsql/plugin/proj

檢查PostGIS是否安裝成功

Error

(1)

[root@Darren2 postgis-2.1.8]# ./configure --with-pgconfig=/usr/local/pgsql/bin/pg_config --with-geosconfig=/opt/geos-3.4.2/bin/geos-config --with-projdir=/opt/proj-4.8.0/ --without-sfcgal

......

checking for xml2-config... no

configure: error: could not find xml2-config from libxml2 within the current path. You may need to try re-running configure with a --with-xml2config parameter.

解決方法：

查看是否存在xml2-config文件，結果不存在

[root@Darren2 postgis-2.1.8]# find / -name "xml2-config"

查看是否已經安裝了libxml2和libxml2-devel

[root@Darren2 postgis-2.1.8]# rpm -qa |grep  libxml2

libxml2-2.7.6-14.el6.x86_64

libxml2-python-2.7.6-14.el6.x86_64

安裝libxml2-devel：

[root@Darren2 postgis-2.1.8]# yum install libxml2-devel -y

[root@Darren2 postgis-2.1.8]# rpm -qa |grep  libxml2

libxml2-2.7.6-21.el6_8.1.x86_64

libxml2-python-2.7.6-21.el6_8.1.x86_64

libxml2-devel-2.7.6-21.el6_8.1.x86_64

可以看到此時已經有xml2-config文件

[root@Darren2 postgis-2.1.8]# find / -name "xml2-config"

/usr/bin/xml2-config

最后再執行上面的編譯命令可成功。
