A) the content is as follows:

On error resume nextset sysenv = CreateObject ("WScript. shell "). environment ("system") 'array object of the system Environment variable Path = CreateObject ("Scripting. fileSystemObject "). getFolder (". "). path 'add variable sysenv ("PGHOME") = "D: \ pgsql" sysenv ("PGHOST") = "localhost" sysenv ("Path") = sysenv ("PGHOME ") + "\ bin;" + sysenv ("Path") sysenv ("PGLIB") = sysenv ("PGHOME") + "\ lib" sysenv ("PGDATA ") = sysenv ("PGHOME") + "\ data" wscript. echo "PostgreSQL environment variable installation successful! No need to restart the computer! "

B) perform the following:

3. Right-click shift in the blank space, open a new cmd window, and cd to d: \ postgresql \ bin;

4. initialize and create a database(Once)

-U: the default encoding format is chs.

-W: Prompt for specifying a password for a Super User

As follows:

4. Start the database

Note: If you are not registered as a system service, you must manually start the service each time. Otherwise, pgadmin3 fails to connect to the database.

Pg_ctl-D d: \ postgresql-l logfile start

After it is started, A logfile file is generated under the main directory installed in the database: D: \ postgresql \ logfile

View the registered service: win + R in the pop-up dialog box, enter services. msc, as shown below:

Net start PostgreSQL to check whether the task is started: Enter tasklist in the command line

Netstat-an allows you to view all IP addresses that are connected to the local computer and uninstall the service. You also need administrator permissions.

2) SC delete PostgreSQL (PostgreSQL)

6. Configure the pgAdmin3 Client

7. Database Connection successful

How can postgresql support remote login?

By default, the remote access to postgresql is unsuccessful. To allow remote access, you need to modify two configuration files as follows:

1. postgresql. conf

Set the value of listen_addresses in this file to "*". In Windows 9.0, this configuration is already "*" and does not need to be modified.

2. pg_cmd.conf

Add the following configuration under the host all 127.0.0.1/32 md5 line after the ipv4 configuration in the configuration file, or directly change this line to the following configuration

Host all 0.0.0.0/0 md5

If you do not want to allow remote access from all IP addresses, you can set 0.0.0.0 in the preceding configuration item to a specific IP address.

Note: The value of listen_addresses is set to "*", which is commented out by default. If this parameter is not commented out, it cannot be accessed, use the built-in pgadmin tool to modify the configuration.

The above is all the content of this article. I hope it will be helpful for your learning and support for helping customers.
