Misc

• Setting up HAProxy

• Prevent out of ports on high traffic webserver due to FIN_WAIT and other issues:

    # Ensure to maximize available ports
    cat /proc/sys/net/ipv4/ip_local_port_range
    echo 1024 65535 >/proc/sys/net/ipv4/ip_local_port_range
  

  and set sockets to reuse

    # sysctl -p
    net.ipv4.tcp_tw_reuse = 1
    net.ipv4.tcp_tw_recycle = 1
