How to to update link between Apache tomcat and PostgreSQL server












0















My company got 2 Ubuntu server (ver 18 )



svr-erpdb (IP :192.168.2.1/24 & GW : 192.168.2.254)
svr-erapp (IP :192.168.2/2/24 & GW : 192.168.2.254)
url 192.168.2.2 to access erp.


Now we setup 2 VM for above 2 erp server at DR Center.
But DR center IP segment is 192.168.1.0 /24



I had did below:



Step 1:Change both server IP address



svr-erpdb change to 192.168.1.67/24 & Gw : 192.168.1.222
svr-erpapp change to 192.168.1.68/24 & Gw : 192.168.1.222
result : able ping both server from client PC


Step 2 : update pg_hba.conf at svr-erpdb



change to 192.168.1.68 from 192.168.2.2


Ori pg_hba.conf



Updated pg_hba.conf



then sudo reboot both server



Step 3 : update postgresql.conf



change ip to 192.168.1.67,192.168.1.68 from 192.168.2.1,192.168.2.1


Ori postgresql.conf



Updated-postgresql.conf



then sudo reboot



Step4 : change URL to new IP



192.168.1.68


Yellow error page come out said : FATAL: no pg_hba.conf entry for host "192.168.1.68", user "postgres", database "symphonydb", SSL off



Error page



update : 17/1/2019
I finally find out the reason why i did all but still received error msg no pg_hpa.conf for host 192.168.1.68



bcos this new ip app-server still keep connected to old db server (192.168.2.2)



so the solution is update the link between app server and db server.



app server installed Apache tomcat 8.0.35 and db server installed postgreSql 10



pls guide me how to update the link between apache tomcat server and postgresql server (mean instruct app server 192.168.1.68 point to db server 192.168.1.67, not 192.168.2.2 anymore)



thanks in advance.
