Welcome wlv001
Say hello to wlv001, my new Linux server. This machine is destined to be my front end Apache box. I have it up and running, but already there have been challenges...
Here are the details on the hardware:
- ASUS RS100-E6/PI2
- Intel® Xeon® Processor X3440
- 8GB 1066MHz DDR3 ECC Reg w/Par CL7 DIMM (Kit of 2) QR, x8 w/Therm Sen
- 2 X Seagate Barracuda 7200.12 SATA 3Gb/s 1TB Hard Drive
- ASUS EN8400GS Silent/P/512M

PostgreSQL on Windows
Download the Windows zip from EnterpriseDB site and unzip to some directory. For this demonstration, I'll assume C:\_apps\pgsql.
C:\>cd \_apps\pgsql
Initialize a new database. This location could be anywhere you like, for simplicity's sake I'll create a directory named data inside the pgsql directory.
C:\_apps\pgsql>mkdir data C:\_apps\pgsql>bin\initdb.exe -D data
After a series of debug messages you should finally receive the following.
WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.
Success. You can now start the database server using:
"bin\postgres" -D "data"
or
"bin\pg_ctl" -D "data" -l logfile startSocial Bookmarks :
