Centos6使用yum安装PostGres以及PostGis
一.安装Postgresql 9.4
1.安装命令：
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
2.初始化PostGres数据库
service postgresql-9.4 initdb
3.添加到自启动服务
chkconfig postgresql-9.4 on
4.修改配置文件
查找pg_hba.conf文件并修改
[root@localhost ~]# find / -name pg_hba.conf
/var/lib/pgsql/9.4/data/pg_hba.conf
[root@localhost ~]# vi /var/lib/pgsql/9.4/data/pg_hba.conf
# TYPE DATABASE USER ADDRESS METHOD
# “local” is for Unix domain socket connections only
local all all peer
# IPv4 local connections:
host all all 0.0.0.0/0 md5
# IPv6 local connections:
host all all ::1/128 ident
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
#host replication postgres 127.0.0.1/32 ident
#host replication postgres ::1/128 ident
查找postgresql.conf
[root@localhost ~]# find / -name postgresql.conf
find / -name postgresql.conf
[root@localhost ~]# vi /var/lib/pgsql/9.4/data/postgresql.conf
将监听的ip改为’*’，取消之前的#注释，注意要取消注释。
# – Connection Settings –
listen_addresses = ‘*’ # what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to ‘localhost’; use ‘*’ for all
# (change requires restart)
#port = 5432 # (change requires restart)
max_connections = 100 # (change requires restart)
5.修改环境变量
找到安装主目录
[root@localhost ~]# find / -name pgsql-9.4
/usr/pgsql-9.4
设置环境变量
[root@localhost ~]# vi /etc/profile
增加以下环境变量
export PGHOME=/usr/pgsql-9.4
export PGDATA=/var/lib/pgsql/9.4/data
export PATH=$PGHOME/bin:$PATH
重新启用profile文件，对更改生效。
source /etc/profile
6.服务启动
service postgresql-9.4 start #初始化启动了一次，所以是restart
8.账户登录
[root@localhost ~]# useradd postgres #新增postgres账户，已有的话，跳过本句，直接执行下一句设置密码
[root@localhost ~]# passwd 123456
#切换到postgres账户
[root@localhost ~]# su – postgres
Last login: Mon Aug 10 10:45:32 CST 2015 on pts/0
#执行psql语句
-bash-4.2$ psql
psql (9.4.4)
Type “help” for help.
postgres=# #这里输入psql命令
二.安装PostGis
yum install postgis2_94
1.如果出现以下情况

2.请先安装以下rpm
#CentOS 7, RHEL 7 64-bit:
sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
# CentOS 6, RHEL 6 64-bit:（这里根据自已的系统版本作选择）
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
3.然后重新安装PostGis
yum install postgis2_94
三。安装pgrouting
yum install pgrouting_94
