CIFS clustering through load balancer

For Linux from Source:

1. Download Balance from the Balance download page.

   Ensure that building toolchains specific to your OS version are installed. For example, GNU Compiler Collection (GCC), GNU make, or any other related packages.

2. Run the following commands to install Balance:

   make
   make install

   This installs Balance at /usr/sbin/ and the man page at /usr/man/man1.

3. Enable Balance to bind on port 445 of the local IPv4 IP address and distribute connections to <host1_IP>, port 445, and <host2_IP>, port 445.

   #balance -fb ::ffff:<IP>  445 <host1_IP>:445 % <host2_IP>:445

   where <IP> is the local IPv4 IP address, <host1_IP> is the IPv4 address of the first server hostname, and <host2_IP> is the IPv4 address of the second server hostname.

1. To configure HAProxy on Solaris, download the appropriate version of HAProxy in accordance to your server (x86 or Sparc).

   For example, haproxy-1.4.18-pcre-solaris10-x86.stripped.gz.

2. Get Perl Compatible Regular Expressions (PCRE) and its dependencies from http://www.pcre.org/.
   1. Unzip the PCRE library.

      gunzip prce-x.x.tar.gz
       tar xf prce-x-x.tar
      cd prce-x.x

   2. Run the following commands:

      ./configure --enable-static --enable-shared --prefix=/usr/local--enable-unicode-properties
      make && make install

3. Create a new user and group with name haproxy.
4. Run the following commands:

   gunzip haproxy-1.4.x-pcre-solaris10-x86.stripped.gz
   mv haproxy-1.4.x-pcre-solaris10-x86.stripped haproxy
   mv haproxy /usr/bin/
   chmod +x /usr/bin/haproxy
   mkdir -p /etc/haproxy

5. Create and edit the /etc/haproxy/haproxy.cfg configuration file by adding the configuration shown below:

   global
       log 127.0.0.1  local0 notice
       user haproxy
       group  haproxy
       chroot /etc/haproxy #directory
       daemon
       nbproc  7
       pidfile /var/run/haproxy.pid
   
   defaults
         log global
         option tcplog
         option redispatch
         contimeout     3000
         clitimeout     5000
         srvtimeout     5000
   
   listen hostname  <IP>:445
         mode tcp
         balance roundrobin
         server hostname <host1_IP>:445 weight  77
         server hostname <host2_IP>:445 weight 179

   Note: Make sure you have /usr/bin in your environment path.
6. Run HAProxy with the following command:

   haproxy -f /etc/haproxy/haproxy.cfg -D
