Add node prodapp03 (centos 6.8) node on haproxy 7-1-2017

Add node prodapp04 (centos 6.8) node on haproxy 14-1-2017

Will remove prodapp02 (centos 5.6) node on haproxy 21-1-2017





Following steps need  need to be done for adding new nodes in production learnexa server

step 1. Maintenance Page On in Haproxy

sudo openconnect na1.cloud-vpn.net 

ssh expprodl@10.166.152.11  ###(login to prodapp01)


cd /home/expprodl/crossbow

./runcap.sh

Enter target environment number [1,2]: 2 (according to environment for ex production or qa )

Enter Cap Task number [1-9]: 9 ——to install maintanence page



step 2. From prodapp01 To  Prdoapp03 , Prodapp04 Nodes Following folder need to be copy for identical configuration  /deploy/crossbow/shared/config/


step 3. vi /etc/fstab #prodapp03  Nodes for  gluster mount

clear log file prodapp03 and prodapp04 

> /deploy/crossbow/shared/log/production.log

prodapp03 and prodapp04 restart servers 

init 6



step 4. Dkim install  Prodapp03 and Prodapp04 steps following link https://wiki.exphosted.com/doku.php/email_server_domain_reputation?s[]=dkim

step 5. Haproxy config file backup and Add New Nodes prodapp03 and prodapp04 Nodes , 

login to haproxy

Haproxy service reload

/etc/init.d/haproxy reload





step 6.New Public for prodapp03 prodapp04


prodapp04 public ip = 198.46.49.166  mail04.learnexa.com

prodapp03 public ip = 198.46.49.161 mail03.learnexa.com

have to add dns entry for forward lookup zone 

For this week end migration learnexa adding new nodes prodapp03  in Production Haproxy Load Balancer


step 7. Maintenance Page Remove in Haproxy

sudo openconnect na1.cloud-vpn.net 

ssh expprodl@10.166.152.11  ###(login to prodapp01)


cd /home/expprodl/crossbow

./runcap.sh

Enter target environment number [1,2]: 2 (according to environment for ex production or qa )



Enter Cap Task number [1-9]: 8 ——to remove maintanence page

Things to do later

1. Memcache roles move from app01 server to Slave DB 

2. Rufus roles move from all app servers to Slave DB
