HAProxy – Instalación, configuración, actualización…..

Pruebas con HAProxy.  Muy buena experiencia general, estupendo balanceo con muuuchas opciones.

Para más información y detalles de HAProxy

Instalar la distribucion de linux deseada, en mi caso opté por Debian, Ubunto lo traé integrado en el repositorio.

Configurar las tarjetas de red con ip´s fijas y las que sean necesarias según el entorno, para ello editamos el fichero /etc/network/interfaces:

Como ejemplo:

nano /etc/network/interfaces

allow-hotplug eth0
auto eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.255.254.0
gateway 10.0.1.254
dns-nameservers 10.0.0.21 10.0.0.22

auto eth0:0
iface eth0:0 inet static
address 10.0.1.1
netmask 255.255.254.0
gateway 10.0.1.254
dns-nameservers 10.0.0.21 10.0.0.22
——————————————————————–

Actualizar el sistema.

apt-get update

apt-get upgrade

apt-get dist-update

INSTALAMOS:

Aquí comienza la instación de los requisitos para HAProxy:

apt-get install build-essential make libpcre3 libpcre3-dev

apt-get install build-essential libssl-dev libpopt-dev git libpcre3-dev

apt-get install linux-kernel-headers  (opcional)

——————————————————————————————————————————————

Opcional para evitar estos avisos o errores con versiones de kernel 2.6.xx:

PCRE library supports JIT : no (USE_PCRE_JIT not set)

PCRE library supports JIT : no (libpcre build without JIT?)

——————————————————————————————————————————————

cd /usr/src/

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.32.tar.gz

tar xzfv pcre-8.32.tar.gz

cd pcre-8.32

./configure –enable-jit –enable-utf && make

——————————————————————————————————————————————
Ahora descargamos el programa HAProxy:

cd /usr/src/

wget http://haproxy.1wt.eu/download/1.5/src/devel/haproxy-1.5-dev21.tar.gz

tar xzfv haproxy-1.5-dev21.tar.gz

cd haproxy-1.5-dev21

—————————————————————————————

chmod +x /etc/init.d/haproxy

update-rc.d haproxy defaults

nano /etc/default/haproxy (creamos el fichero de configuración para habilitarlo)

————————————————————————————

# Set ENABLED to 1 if you want the init script to start haproxy.
ENABLED=1
# Add extra flags here.
#EXTRAOPTS=»-de -m 16″

—————————————————————————————

groupadd haproxy
useradd -g haproxy haproxy

mkdir /etc/haproxy

mkdir /etc/haproxy/errors

cp /usr/src/haproxy-1.5-dev21/examples/errorfiles/* /etc/haproxy/errors

nano /etc/haproxy/haproxy.cfg

service haproxy restart

Ya estaría funcionando.

——————————————————————————————————————————————

Lo siguiente es para organizar los logs y que se eliminen pasado un tiempo (28 días).

nano /etc/rsyslog.d/haproxy.conf

if ($programname == ‘haproxy’ and $syslogseverity-text == ‘info’) then -/var/log/haproxy/haproxy-info.log
& ~
if ($programname == ‘haproxy’ and $syslogseverity-text == ‘notice’) then -/var/log/haproxy/haproxy-notice.log
& ~

nano /etc/logrotate.d/haproxy

/var/log/haproxy/*.log {
daily
missingok
rotate 28
compress
delaycompress
notifempty
create 644 root adm
sharedscripts
postrotate
/etc/init.d/haproxy reload > /dev/null
endscript
}

——————————————————————————————————————————————

Para actualizar o cambiar de versión de HAProxy:

cd /usr/src/haproxy-xxxxxx
make clean
make TARGET=linux2628 CPU=native ARCH=x86_64 USE_LINUX_SPLICE=1 USE_LIBCRYPT=1 USE_POLL=default USE_ZLIB=1 USE_LINUX_TPROXY=1 USE_OPENSSL=1 USE_STATIC_PCRE=1 USE_PCRE_JIT=1 PCRE_INC=/usr/src/pcre-8.32/ \PCRE_LIB=/usr/src/pcre-8.32/.libs
sudo make install

Ya estaría cambiada la versión.

——————————————————————————————————————————————

Reiniciar el servicio sin apenas parada, aunque de por sí es muy rápido.

haproxy -f /etc/haproxy/haproxy.cfg -p /var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid)

haproxy -f configfile -sf

——————————————————————————————————————————————

Si queremos tener varios HAProxy por si falla el principal que tome el control otro, podemos utilizar Keepalived.

Primero lo instalamos.

apt-get install -y keepalived

update-rc.d keepalived defaults

echo «net.ipv4.ip_nonlocal_bind = 1» >> /etc/sysctl.conf
sysctl -p

La configuración del principal o master sería (XXX.XXX.XXX.XXX = IP Virtual deseada):

Master

nano /etc/keepalived/keepalived.conf

———————————————————————————————–

vrrp_script chk_haproxy {
script «killall -0 haproxy»   # verify the pid existance
interval 2                    # check every 2 seconds
weight 2                      # add 2 points of prio if OK
}

vrrp_instance VI_1 {
interface eth0                # interface to monitor
state MASTER
virtual_router_id 51          # Assign one ID for this route
priority 101                  # 101 on master, 100 on backup
virtual_ipaddress {
XXX.XXX.XXX.XXX            # the virtual IP
}
track_script {
chk_haproxy
}
}

La configuración del backup o esclavo sería (XXX.XXX.XXX.XXX = IP Virtual deseada):

Esclavo

nano /etc/keepalived/keepalived.conf

vrrp_script chk_haproxy {
script «killall -0 haproxy»   # verify the pid existance
interval 2                    # check every 2 seconds
weight 2                      # add 2 points of prio if OK
}

vrrp_instance VI_1 {
interface eth0                # interface to monitor
state MASTER
virtual_router_id 51          # Assign one ID for this route
priority 100                  # 101 on master, 100 on backup
virtual_ipaddress {
XXX.XXX.XXX.XXX            # the virtual IP
}
track_script {
chk_haproxy
}
}

————————————————————————————————–

/etc/init.d/keepalived start

ip a | grep -e inet.*eth0

cat /var/log/messages | grep VRRP_Instance

——————————————————————————————————————————————

Para comprobar si la configuración del HAProxy es correcta antes de ponerla en producción:

haproxy -f /etc/haproxy/haproxy.cfg -c
——————————————————————————————————————————————

Saber versión instalada de HAProxy y compilación:

haproxy -vv
