[root@node01 ~]# chown -R postgres.postgres /software*
[root@node01 ~]# chown -R postgres.postgres /stage*

4、切换postgres用户，并解压安装包
[root@node01 stage]# su - postgres
[postgres@node01 ~]$ cd /stage/
[postgres@node01 stage]$ ll

[postgres@node01 stage]$ tar -xvf postgresql-10.14-1-linux-x64-binaries.tar.gz

5、初始化
[postgres@node01 stage]$ /stage/pgsql/bin/initdb -D /software/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".

7、登陆数据库
[postgres@node01 stage]$ psql -Upostgres -dpostgres
psql.bin (10.14)
