检查PostGIS是否安装成功
Darren2:postgres:/usr/local/pgsql:>psql
postgres=# select * from pg_available_extensions where name like 'postgis%';

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.
解决方法：
查看是否存在xml2-config文件，结果不存在
[root@Darren2 postgis-2.1.8]# find / -name "xml2-config"
查看是否已经安装了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
安装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
可以看到此时已经有xml2-config文件
[root@Darren2 postgis-2.1.8]# find / -name "xml2-config"
/usr/bin/xml2-config
最后再执行上面的编译命令可成功。
(2)创建extension时报错
postgres=# create extension postgis;
