在CentOS 6.3 安裝postgresql9.5

一、安裝準備

需要安裝的包：

      yum install postgresql95-devel-9.5.5-1PGDG.rhel6.x86_64.rpm

     檔案可以從官網下載下傳。http://yum.postgresql.org/repopackages.php

作業系統：

     CentOS release 6.3 (Final)

     安裝時如果提示yum源不對，注意調整rpm源如下：

[[email protected] yum.repos.d]# cat pgdg-95-redhat.repo

[pgdg95]

name=PostgreSQL 9.5 $releasever - $basearch

baseurl=https://download.postgresql.org/pub/repos/yum/9.5/redhat/rhel-$releasever-$basearch

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG-95

[pgdg95-source]

name=PostgreSQL 9.5 $releasever - $basearch - Source

failovermethod=priority

baseurl=https://download.postgresql.org/pub/repos/yum/srpms/9.5/redhat/rhel-$releasever-$basearch

enabled=0

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG-95

二、開始安裝：

      yum install postgresql95-devel-9.5.5-1PGDG.rhel6.x86_64.rpm

      yum install postgresql95-server postgresql95-contrib

三、初始化資料庫：

　　mkdir -p /data/postgres/pgsql/data

　　chown -R postgres.postgres /data/postgres/

   （1）先切換到postgres使用者

　　[[email protected] yum.repos.d]# su - postgres

   （2）如果初始化成功，會有如下提示：

-bash-4.1$ /usr/pgsql-9.5/bin/initdb -D /data/postgres/pgsql/data

The files belonging to this database system will be owned by user "postgres".

This user must also own the server process.

The database cluster will be initialized with locale "en_US.UTF-8".

The default database encoding has accordingly been set to "UTF8".

The default text search configuration will be set to "english".

Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections

You can change this by editing pg_hba.conf or using the option -A, or

--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

/usr/pgsql-9.5/bin/pg_ctl -D /data/postgres/pgsql/data -l logfile start

-bash-4.1$

四、啟動資料庫：

$ /usr/pgsql-9.5/bin/pg_ctl -D /data/postgres/pgsql/data -l /tmp/postrest.log start

server starting

五、建立db

createdb mysql2gp_sy

六、登入資料庫：

$ psql -h 127.0.0.1 -d mysql2gp_sy -U postgres

psql (9.5.6)

Type "help" for help.

mysql2gp_sy=#

至此，安裝成功。
