CentOS7 安装 PostGIS方法（适合国内网络）

安装Postgresql 9.4

yum install http://yum.postgresql.org/9.4/redhat/rhel-6-x86_64/pgdg-redhat94-9.4-1.noarch.rpm
yum install postgresql94-server postgresql94-contrib
service postgresql-9.4 initdb
chkconfig postgresql-9.4 on

安装Postgis

yum install postgis2_94

如果提示缺少一大堆依赖库，则需要安装对应源，

#CentOS 7, RHEL 7 64-bit:
sudo http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

# CentOS 6, RHEL 6 64-bit:
sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

# CentOS 6, RHEL 6 32-bit:
sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

# CentOS 5, RHEL 5 64-bit:
sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

# CentOS 5, RHEL 5 32-bit:
sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

这里网络被墙，不能导入，改用阿里云源（针对centos7
