postgres 数据库的安装

环境：Linux version 2.6.32-642.el6.x86_64   软件版本：postgresql-9.6.8.tar.gz

新项目要上线测试，要求安装一个PG 的数据库

我们进行的是源码包的安装

1：下载源码包

2：安装数据库需要的依赖包

yum install -y perl-ExtUtils-Embed readline-devel zlib-devel pam-devel libxml2-devel libxslt-devel openldap-devel python-devel gcc-c++ openssl-devel cmake

3：解压源码包

[root@oracle soft]# tar -xvf postgresql-9.6.8.tar.gz

4：创建 需要的目录

[root@oracle soft]# mkdir postgres
[root@oracle soft]# mkdir pgsql

5：进入解压后的目录

[root@oracle soft]# cd postgresql-9.6.8

6：开始编译安装PostgreSQL 数据库

[root@oracle postgresql-9.6.8]# ./configure --prefix=/data/soft/postgres

7：执行gmake

8:执行gmake install

9:创建postgresql 的数据目录

[root@oracle soft]# mkdir pgsql

[root@oracle ~]# groupadd postgres
[root@oracle ~]# useradd -g postgres postgres

[root@oracle soft]# chown postgres:postgres /data/soft/postgres -R
[root@oracle soft]# chown postgres:postgres /data/soft/pgsql -R
[root@oracle soft]# chmod 700 /data/soft/pgsql -R

10：配置环境变量

[postgres@oracle ~]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
export PATH=/data/soft/postgresql/bin:$PATH
export PGDATA=/data/soft/pgsql

11:初始化数据库 指定数据目录

[postgres@oracle ~]$ /data/soft/postgres/bin/initdb -D /data/soft/pgsql/
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:

/data/soft/postgres/bin/pg_ctl -D /data/soft/pgsql/ -l logfile start

12：启动数数据库

[postgres@oracle ~]$ /data/soft/postgres/bin/pg_ctl start
server starting
[postgres@oracle ~]$ LOG: database system was shut down at 2018-05-22 15:11:11 CST
LOG: MultiXact member wraparound protections are now enabled
LOG: database system is ready to accept connections
LOG: autovacuum launcher started

13：创建数据库

[postgres@oracle ~]$ psql
-bash: psql: command not found
如果报上面的错误说明你的你的程序的路径不在path变量中,用绝对路径调用下你的psql看看

postgres=# create user lhh with login password 'm2i3sc@newnet';

^
postgres=# grant all privileges on database nntlds to lhh;

到这一个postgresql 数据库就算搭建完成了。
