Code: Select all

[root@lkennagiost01 ~]# tail -55 /var/lib/pgsql/pgstartup.log
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".

Success. You can now start the database server using:

or
    /usr/bin/pg_ctl -D /var/lib/pgsql/data -l logfile start

You have new mail in /var/spool/mail/root
[root@lkennagiost01 ~]#
so I ran those two cmd lines and got:

You have new mail in /var/spool/mail/root

Code: Select all

[root@lkennagiost01 ~]# /usr/bin/postgres -D /var/lib/pgsql/data
"root" execution of the PostgreSQL server is not permitted.
The server must be started under an unprivileged user ID to prevent
possible system security compromise.  See the documentation for
more information on how to properly start the server.
[root@lkennagiost01 ~]# /usr/bin/pg_ctl -D /var/lib/pgsql/data -l logfile start
pg_ctl: cannot be run as root
Please log in (using, e.g., "su") as the (unprivileged) user that will
own the server process.
and THEN

Code: Select all

[root@lkennagiost01 ~]# /var/spool/mail/root
-bash: /var/spool/mail/root: Permission denied
I dont get it I made no changes to my system. I cant even get to var log messages.

Is there a way to see who made changes to my machine and what those changes were?

Well, this is an esoteric error. Rare indeed.
There was a postgres bug floating around for a while, does the following command fail due to a detected loop?

Code: Select all

find -L /usr/share/zoneinfo/
Lets also get an strace of this:

Code: Select all

yum install -y strace
su postgres
strace -o gregtest -ff -t pg_ctl start -D /var/lib/pgsql/data -l /tmp/postgres.startup.log
Once it stops, ctrl-c it and PM me a copy of /tmp/postgres.startup.log.
