Working VRRP

After crawling websites, manual pages, made working config for proxies.

Just change priority, and maybe state

global_defs {
   notification_email {
       admin@mail.com
   }
   # The address to use in the From: header
   notification_email_from admin@mail.com

   # The SMTP server to route mail through
   smtp_server 1.1.1.1

   # How long to wait for the mail server to respond
   smtp_connect_timeout 30

   # A descriptive name describing the router
   router_id VRRP-director2
}

# Create a VRRP instance
vrrp_instance VRRP_ROUTER1 {

    # The initial state to transition to. This option isn't
    # really all that valuable, since an election will occur
    # and the host with the highest priority will become
    # the master. The priority is controlled with the priority
    # configuration directive.
    state BACKUP

    # The interface keepalived will manage
    interface eth0

    mcast_src_ip 2.2.2.155

    # The virtual router id number to assign the routers to
    # ID SHOULD BE SAME ON REDUNDANT UNITS!
    virtual_router_id 50

    # The priority to assign to this device. This controls
    # who will become the MASTER and BACKUP for a given
    # VRRP instance.
    # HIGHER - MORE CHANCE TO BECOME ACTIVE!
    priority 150

    # How many seconds to wait until a gratuitous arp is sent
    garp_master_delay 2

    # How often to send out VRRP advertisements
    advert_int 1

    # Execute a notification script when a host transitions to
    # MASTER or BACKUP, or when a fault occurs. The arguments
    # passed to the script are:
    #  $1 - "GROUP"|"INSTANCE"
    #  $2 = name of group or instance
    #  $3 = target state of transition
    # Sample: VRRP-notification.sh VRRP_ROUTER1 BACKUP 100
    notify_master "/config/proxy-up"
    notify_backup "/config/proxy-down"


    # Send an SMTP alert during a state transition
    #smtp_alert

    # Authenticate the remote endpoints via a simple
    # username/password combination
    authentication {
        auth_type PASS
        auth_pass 1533524254
    }
    # The virtual IP addresses to float between nodes. The
    # label statement can be used to bring an interface
    # online to represent the virtual IP.
    virtual_ipaddress {
        2.2.2.2/29 dev eth0 label eth0:0
    }
}
