The final directory structure as shown below:
Dependent test environment
By entering the cmd command window to the bindirectory, execute the following command

3, create and initialize the data directory
Create a data directory
My environment data directory is located at: D:\PGData, has been ahead of the new directory, make sure that this directory exists
Initialization data directory
Specifies the super administrator user name: postgres, enter cmd into the command window by bindirectory, execute the following command,
C:\Program Files\PostgreSQL\pgsql\bin>initdb -D "D:\PGData" -E UTF-8 --locale=chs -U postgres -WAfter the successful implementation of the following figure:
By -Wyou will be prompted to enter the root password parameters
Note authority, if the data directory is in c drive, you need to add to the user full control
5, the configuration database postgres
Configuration file located in the data directory: D:\PGDataas shown below
Open and modify postgresql.conf
By text editor to open the postgresql.conf, modify listen_addressesparameters
before fixing:
Modified:
Open and modify pg_hba.conf
By text editor to open the postgresql.conf, a new authorization allows the remote host (without limitation IP), database access through encrypted passwords
After modification, as shown below:
4, Installation Services
As an administrator to enter C:\Program Files\PostgreSQL\pgsql\binthe directory, run the command to the database way to manage windows services running:
C:\Program Files\PostgreSQL\pgsql\bin\pg_ctl register -D "D:\PGData" -N postgresql-12_1_3-x64 -S auto -U "NT AUTHORITY\LocalService"Account privileges Description:
| account name | Account ID |
|---|---|
| Local Service | NT AUTHORITY\LocalService |
| 网络服务 | NT AUTHORITY\NetworkService |
安装成功后如下图：
然后进入windows服务管理器，启动服务：
若服务启动失败，或者需要更换数据存放目录可以取消注册服务：
C:\Program Files\PostgreSQL\pgsql\bin\pg_ctl unregister -N postgresql-12_1_3-x646、创建用户、数据库
连接数据库
打开cmd窗口，通过psql终端测试数据库是否可用，使用超级用户postgres连接默认的postgres数据库，执行如下命令：
C:\Users\admin>psql -d postgres -U postgres连接成功后如下图：
创建用户、数据库
- 创建用户
CREATE USER dba WITH PASSWORD 'dba' SUPERUSER;
- 创建数据库
CREATE DATABASE exampledb OWNER dba;
- 切换用户及数据库
\c exampledb dba;
到此，postgres数据库的搭建已经完成，接下来可以愉快的使用了。
