1、下載地址 https://www.enterprisedb.com/download-postgresql-binaries
2、創建用戶並修改密碼
[root@node01 ~]# useradd postgres
[root@node01 ~]# passwd postgres
Changing password for user postgres.
New password:
BAD PASSWORD: The password contains the user name in some form
Retype new password:
passwd: all authentication tokens updated successfully.
[root@node01 ~]# id postgres
uid=1000(postgres) gid=1000(postgres) groups=1000(postgres)
3、創建目錄並授權
[root@node01 ~]# mkdir /software/pgsql_data ---------數據目錄
[root@node01 ~]# mkdir -p /stage ---------軟件安裝目錄
[root@node01 ~]# chown -R postgres.postgres /software*
[root@node01 ~]# chown -R postgres.postgres /stage*
4、切換postgres用戶，並解壓安裝包
[root@node01 stage]# su - postgres
[postgres@node01 ~]$ cd /stage/
[postgres@node01 stage]$ ll
total 156744
-rw-r--r-- 1 postgres postgres 160504039 Aug 17 23:11 postgresql-10.14-1-linux-x64-binaries.tar.gz
[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".
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:
/stage/pgsql/bin/pg_ctl -D /software/pgsql_data -l logfile start
6、啟動數據庫
[postgres@node01 stage]$ /stage/pgsql/bin/pg_ctl -D /software/pgsql_data -l logfile start
waiting for server to start.... done
server started
7、登陸數據庫
[postgres@node01 stage]$ psql -Upostgres -dpostgres
psql.bin (10.14)
Type "help" for help.
postgres=#
8、關閉數據庫
[postgres@node01 stage]$ /stage/pgsql/bin/pg_ctl -D /software/pgsql_data -l logfile stop
waiting for server to shut down.... done
server stopped
9、擴展
postgres=# \l ---------列出所有的database
postgres=# \c test ----------選擇database
test=# \d ----------列出所用database的表
test=# \d tablename ----------查看表結構
test=# \q ---------退出登陸
