Amazon экземпляр Linux, работающий beanstalkd

Добавить alias k='kate'. Вот ссылка еще на некоторую информацию о псевдонимах удара.

Вы не можете передать параметр в псевдоним. Можно сделать CD dir_name" => "CD dir_name; ls-l с функцией и псевдонимом как так

mcd () { cd "$1" && ls -l; }
alias cd='mcd'

Это только выполнится ls -l если cd успешно.

I ended up writing a user data script that runs when an ec2 instance is created. The script pulls down the latest source for beanstalkd, compiles, and installs the binary. The script uses a modified upstart script to control the lifecycle of the beanstalkd process.

Here's the user data script:

#!/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

The two scripts it's downloading from gist is the upstart beanstalkd script and a configuration file which sets the options used when running the program.

Here's the upstart beanstalkd.conf script:

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

Here's the configuration file copied into /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
fi
