This project is for Linux server administrators. Here are the task details.
1. Need to setup HAProxy load balancing. We have two servers having two ip address from two different ISP. If one server goes down then all traffic must be sent to another server.
1. We have have two identical Centos 7 servers. We will say these two servers A and B. Server A is the master server, publicly available. While server B is the back up server. Currently syncing between A to B is implemented. The following syncing are done......
i). Web server syncing is done using Rsync Linux package. Any changes made in server A root directory will automatically take effect at server B's root directory. Now you have to do same thing for server B to A.
ii). Both server A and B has MySQL installed. Server A has master MySQL installation and B has salve MySQL installation. Now you have to do B to A configuration.
iii). If any server goes down or if server A or B can't communicate to each other, a mail must be sent to the administrator email address to take over the issue.
2. Both server A and B need FTP server installation and syncing. So creating FTP account in one server will sync to another server immediately. We can can connect any of them using FTP accounts that we want.
3. We have two email servers in our office. These two email servers are A and B. Server A is completely installed with POSTFIX, dovecot. Server A sends outgoing email using postfix via another postfix mail server C. Server A stores all incoming emails. Now you need do the same for server B. Need to do IMAP syncing for both server A and B. If server A goes down server B must take care of all the things. Like MX records DNS entry. Mail server must not go down. Need to do high availability email server.
