# PURE LOAD BALANCER - Sample configuration file
#
# Put this file into /etc/plb.conf, or run the load balancer with
# plb -c /path/to/plb.conf
#
# This is the IP address and port the load balancer answers on.
# To listen to all interfaces, just use 0.0.0.0 for the IP address.
listen_ip 0.0.0.0
listen_port 80
# Bind family. 0 for IPv4, 1 for IPv6.
bind_ipv6 0
# Protocol to balance : HTTP (SMTP is not implemented yet)
protocol HTTP
# IP addresses of the real web servers. Use space as a separator.
# IPv4 and IPv6 addresses are allowed.
servers_ip 10.1.1.1 10.1.1.2 10.1.1.3
servers_port 80
# After binding ports, the load balancer chroots to an empty (recommended)
# directory, and drops privileges.
user nobody
group nobody
chroot_dir /var/empty
# Timeouts to avoid clients use unneeded slots on your servers
# with idle connections. Values are in seconds.

# When a server goes down, the load balancer will try to probe it at regular
# interval in order to bring it back to life.
# This is the delay, in seconds, between probes.
timeout_cleanup 15
# Really mark a server down after this many consecutive failures.
server_retry 5
# The total maximal number of clients to allow
max_clients 1000
# The backlog. Try something like (max_clients / 10) for extreme cases.
backlog 100
# The log file verbosity.
# 0 => everything, including debugging info (not recommended)
# 1 => all errors, all warnings, all common notifications
# 2 => all errors, all warnings
# 3 => quiet mode, fatal errors only
# default is 2. Leave this commented if you want to override it with
# the -d command-line switch.
# log_level 2
# By default, PLB will send error to the standard error file descriptor,
# thus making it possible to use software like multilog.
# If you want the load balancer to directly write to a file, uncomment the
# following line :
# log_file /var/log/plb.log
