Hello team,

 

We have the data directory under /var/lib/pgsql/9.3/data/

 

FYI. Below are the permissions to group and user on each directory. Please do help .

 

drwxr-xr-x. 19 root root  267 Nov 22 08:42 var/

drwxr-xr-x. 30 root root 4096 Nov 23 09:09 lib/

-rwx------. 1 postgres postgres 20124 Nov 24 03:42 postgresql.conf

 

Also we have change the below parameters in Postgres.conf file to resolve the issue but still not resolved.

 

listen_addresses = '*                                  

port = 5432                            

max_connections = 100                  

unix_socket_directories = '/tmp'       

unix_socket_group = ''                 

unix_socket_permissions = 0777

Daulat

It appears the permissions with your data directory have changed. According to the error message, you should set the appropriate permissions for /var/lib/pgsql/9.3/data

Hi team,

 

But it was working fine earlier.

 

Another message I have seen after starting by

-bash-4.2$  /usr/pgsql-9.3/bin/pg_ctl -D /var/lib/pgsql/9.3/data/ -l logfile start

It seems you may have just the postgresql package installed and not the postgresql-server package. This Linode guide may be helpful:

Hi team,

 

We are facing the below issue while logging with postgres as given below:

 

[centos@ip-192-90-2-208 ~]$ su - postgres

Password:

Last login: Thu Nov 23 16:15:45 UTC 2017 on pts/1

-bash-4.2$ psql

psql: could not connect to server: No such file or directory

        Is the server running locally and accepting

        connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

-bash-4.2$

 

 

OS: Centos

AWS environment
