| 1、解压数据库 |
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
cd /usr/local/src |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| tar -jxvf postgresql-8.4.14.tar.bz2 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 2、进入数据库文件 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| cd postgresql-8.4.14 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
将数据库安装指定到特定的目录postgresql |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| (postgresql文件夹是新建) |
|
|
|
|
|
|
|
| ./configure --prefix=/usr/local/postgresql/ |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 有可能出现以下报错提示找不到readline，但readline已经安装，说明缺少了readline-devel可通过yum安装 |
|
|
| Ａ、配置/etc/yum.repos.d/rhel-debuginfo.repo (注意linux版本不一样配置也会有所不同) |
|
|
|
|
|
|
| [base] |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
| name=Server Local Sources |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| baseurl=file:///media/rhel/Server |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| enable=1 |
|

|
|
|
|
| gpcheck=1 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| gpgkey=file:///media/rhel/RPM-GPG-KEY-redhat-release |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Ｂ、挂载光驱的系统盘 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 新建一个目录用于挂载点：mkdir /media/rhel |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| mount /dev/cdrom /media/rhel |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| Ｃ、验证挂载是否成功查看df -Th |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| Ｄ、yum安装相关软件 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| yum makecache 清理缓存 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| yum install readline -devel |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| yum install read* |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 3、编译&安装 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| gmake |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| gmake install |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 4、增加postgresql专用用户 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| useradd postgres |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 5、切换postgres用户之前，先建立数据目录data并赋给postgres用户 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| mkdir /postgresql/data |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| chown postgres /usr/local/postgresql/data |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| su - postgres |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 6、初始化目录数据 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| /usr/local/postgresql/bin/initdb -D /usr/local/postgresql/data |
|
|
|
|
|
|
|
|
|
|
|
|
| /usr/local/postgresql/bin/postgres -D /usr/local/postgresql/data >logfile 2>&1 & |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 7、启动postgresql数据库 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| /usr/local/postgresql/bin/postgres -D /usr/local/postgresql/data |
|
|
|
|
|
|
|
|
|
|
|
| 启动报如下错误 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| LOG: could not translate host name "localhost",service "5432" to address: Name or service not known |
| WARNING: could not create listen socket for "localhost" |
|
|
|
|
|

|
|
|
|
|
|
|
| FATAL: could not create any TCP/IP sockets |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 解决办法是：修改/etc/hosts |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 增加了 127.0.0.1 localhost localhost.localdomain |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 8、再次启动postgresql |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
/usr/local/postgresql/bin/postgres -D /usr/local/postgresql/data |
|
|
|
|
|
|
|
|
|
|
|
|
| 出现如下提示，说明数据库安装成功 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| LOG:database system was shut down at 2012-12-10 10:22:40 CST |

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
8、以后台服务方式启动之前，切换到root在/usr/local/postgresql/data/创建logfile文件，并赋用户postgres
|
| $su - root |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| touch /usr/local/postgresql/data/logfile |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| chown postgres logfile |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| /usr/local/postgresql/bin/postgres -D /usr/local/postgresql/data >logfile 2>&1 & |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 9、数据库的启动与关闭 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| $ cd /usr/local/postgresql/bin |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| ./pg_ctl -D /usr/local/postgresql/data start |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| ./pg_ctl -D /usr/local/postgresql/data stop |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 10、创建数据库及连接数据库 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| /usr/local/pgsql/bin/createdb test |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
/usr/local/pgsql/bin/psql test
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 11、数据库的一些相关配置 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 允许远程连接 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| postgresql因为安全方面的考虑，默认情况下只接受本机的连接。为了管理的方便，我们需要开通远程连接。 |
|
| 修改data/postgresql.conf，增加： |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 修改监听端口： |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 修改data/pg_hba.conf，增加md5那一行： |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 然后重启posgtres。 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 修改配置后马上生效不重启： |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| cd /usr/local/postgresql/bin |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
pg_ctl reload
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 12、把Postgres服务设置为自动启动 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 进入postgresql的源代码解压目录:cd /usr/local/src/postgresql-8.4.14 |
|
|
|
|
|
|
|
|
|
|
|
| #cp contrib/start-scripts/linux /etc/init.d/postgresql |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| #chmod a+x /etc/init.d/postgresql |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| #cd /etc/init.d/ |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| #chkconfig --add postgresql |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
#chkconfig postgresql --level 345 on
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
13、在postgresql中创建用户，并设置数据库 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| create database test owner test; |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 这样就设置了一个数据库叫test，并且它的拥有者是一个叫test的用户 |
