Redhat6安装postgresql

系统运维

yum install http://yum.postgresql.org/9.4/redhat/rhel-6-x86_64/pgdg-redhat94-9.4-1.noarch.rpm

yum install postgresql-server

发现如下问题：Error: Package: postgresql93-contrib-9.3.5-1PGDG.rhel6.i686 (pgdg93) Requires: libcrypto.so.10(libcrypto.so.10)

su postgres

yum install http://mirror.centos.org/centos/6/os/x86_64/Packages/openssl-1.0.1e-30.el6.x86_64.rpm

yum install postgresql-server
service postgresql-9.4 initdb
chkconfig postgresql-9.4 on

find / -name \'pg_hba.conf\'

vim /var/lib/pgsql/9.4/data/pg_hba.conf

# local is for Unix domain socket connections only

su postgres

psql

yum install postgresql-odbc

=====================================================================

wget ftp://ftp.unixodbc.org/pub/unixODBC/unixODBC-2.3.2.tar.gz

make
make install

这时，unixodbc已经安装完毕，这时候可以使用odbc的通用api进行编程了。

但是如果要操作具体的数据库，还需要相应数据库提供的odbc驱动，比如操作mysql的ODBC驱动，下载地址是：http://dev.Mysql.com/downloads/connector/odbc/5.1.html。
