instância do Amazon Linux executando o beanstalkd

Question

Qual é a melhor maneira de executar o beanstalkd em uma instância do Amazon Linux no EC2? O Beanstalkd não existe no repositório yum e o script upstart incluído no beanstalkd não parece funcionar imediatamente. Eu estou querendo saber se alguém já resolveu este problema, ou se eu preciso ir me esquivar com um script personalizado de dados de usuário EC2 + script upstart beanstalkd.

    

Answer 1

Acabei escrevendo um script de dados do usuário que é executado quando uma instância do ec2 é criada. O script puxa a última fonte para o beanstalkd, compila e instala o binário. O script usa um script upstart modificado para controlar o ciclo de vida do processo beanstalkd.

Aqui está o script de dados do usuário:

#!/bin/bash -ex
set -e -x

# Log output
exec > >(tee /var/log/user-data.log|logger -t user-data -s 2>/dev/console) 2>&1

# Update yum first
yum groupinstall "Development Tools" -y 
yum update -y

# Download /etc/default/beanstalkd
curl -J -O https://gist.github.com/phaitour/6482469/download
tar -zxvf *.tar.gz
/bin/cp -f gist*/beanstalkd /etc/default/ 
ln -s /etc/default/beanstalkd /etc/beanstalkd.conf 
rm -rf gist*

# Download /etc/init/beanstalkd.conf
curl -J -O https://gist.github.com/phaitour/6482467/download
tar -zxvf *.tar.gz
/bin/cp -f gist*/beanstalkd.conf /etc/init/
rm -rf gist*

# Create beanstalkd user
/usr/sbin/useradd -c "beanstalk user" -s /bin/false -r -m -d /var/lib/beanstalkd/ beanstalkd

# Compile latest version of beanstalkd
wget https://github.com/kr/beanstalkd/archive/v1.9.tar.gz
tar -zxvf v1.9.tar.gz
cd beanstalkd-1.9
make
mv beanstalkd /usr/bin/beanstalkd-1.9
cd /usr/bin
rm -rf beanstalkd
ln -s beanstalkd-1.9 beanstalkd

# Start beanstalks with upstart
initctl reload-configuration
initctl start beanstalkd

Os dois scripts que está baixando do gist são o script beanstalkd upstart e um arquivo de configuração que define as opções usadas durante a execução do programa.

Aqui está o script beanstalkd.conf inicializado:

description "simple, fast work queue"

start on runlevel [2345]
stop on runlevel [!2345]

respawn
respawn limit 5 2

expect fork

script
    . /etc/default/beanstalkd
    exec su -c "exec /usr/bin/beanstalkd $BEANSTALKD_OPTIONS"
end script

Aqui está o arquivo de configuração copiado em / etc / default / beanstalkd:

# Set some constants to be used to construct BEANSTALKD_OPTIONS

BEANSTALKD_ADDR=0.0.0.0
BEANSTALKD_PORT=11300
BEANSTALKD_USER=beanstalkd
BEANSTALKD_BINLOG_DIR=/var/lib/beanstalkd
BEANSTALKD_BINLOG_FSYNC_PERIOD=0



# Create the actual BEANSTALKD_OPTIONS string
# Copied from https://gist.github.com/shiki/515422

BEANSTALKD_OPTIONS="-l ${BEANSTALKD_ADDR} -p ${BEANSTALKD_PORT} -u ${BEANSTALKD_USER}"
if [ "${BEANSTALKD_MAX_JOB_SIZE}" != ""  ]; then
    BEANSTALKD_OPTIONS="${BEANSTALKD_OPTIONS} -z ${BEANSTALKD_MAX_JOB_SIZE}"
fi

if [ "${BEANSTALKD_BINLOG_DIR}" != "" ]; then
    if [ ! -d "${BEANSTALKD_BINLOG_DIR}" ]; then
        echo "Creating binlog directory (${BEANSTALKD_BINLOG_DIR})"
        mkdir -p ${BEANSTALKD_BINLOG_DIR} && chown ${BEANSTALKD_USER}:${BEANSTALKD_USER} ${BEANSTALKD_BINLOG_DIR}
    fi
    BEANSTALKD_OPTIONS="${BEANSTALKD_OPTIONS} -b ${BEANSTALKD_BINLOG_DIR}"
    if [ "${BEANSTALKD_BINLOG_FSYNC_PERIOD}" != "" ]; then
        BEANSTALKD_OPTIONS="${BEANSTALKD_OPTIONS} -f ${BEANSTALKD_BINLOG_FSYNC_PERIOD}"
    else
        BEANSTALKD_OPTIONS="${BEANSTALKD_OPTIONS} -F"
    fi
    if [ "${BEANSTALKD_BINLOG_SIZE}" != "" ]; then
        BEANSTALKD_OPTIONS="${BEANSTALKD_OPTIONS} -s ${BEANSTALKD_BINLOG_SIZE}"
    fi
