下载redis_exporter

wget https://github.com/oliver006/redis_exporter/releases/download/v0.15.0/redis_exporter-v0.15.0.linux-amd64.tar.gz

tar -zxvf redis_exporter-v0.15.0.linux-amd64.tar.gz -C /usr/local/redis_exporter

编写启动脚本

cd /usr/local/redis_exporte

ln -s redis_exporter /usr/sbin/redis-exporter

mkdir bin

cd bin

vim redis-exporter.sh

#!/bin/bash

basedir=$(cd `dirname $0`/..; pwd)

redis_host=localhost

redis_port=6379

redis_password=abc123

RETVAL=0

PROG="redis-exporter"

EXEC="/usr/sbin/redis-exporter"

LOCKFILE="/var/lock/subsys/$PROG"

OPTIONS="-redis.addr $redis_host:$redis_port -redis.password $redis_password"

# Source function library.

if [ -f /etc/rc.d/init.d/functions ]; then

  . /etc/rc.d/init.d/functions

else

  echo "/etc/rc.d/init.d/functions is not exists"

  exit 0

fi

start() {

  if [ -f $LOCKFILE ]

  then

    echo "$PROG is already running!"

  else

    echo -n "Starting $PROG: "

    nohup $EXEC $OPTIONS >/dev/null 2>&1 &

    RETVAL=$?

    [ $RETVAL -eq 0 ] && touch $LOCKFILE && success || failure

    echo

    return $RETVAL

  fi

}

stop() {

  echo -n "Stopping $PROG: "

  killproc $EXEC

  RETVAL=$?

  [ $RETVAL -eq 0 ] && rm -r $LOCKFILE && success || failure

  echo

}

restart ()

{

  stop

  sleep 1

  start

}

case "$1" in

  start)

    start

    ;;

  stop)

    stop

    ;;

  status)

    status $PROG

    ;;

  restart)

    restart

    ;;

  *)

    echo "Usage: $0 {start|stop|restart|status}"

    exit 1

esac

exit $RETVAL

如果redis没有密码，就不需要-redis.password

启动脚本并验证

./redis-exporter.sh start

curl localhost:9121/metrics

加入Prometheus

    - job_name: 'redis'

        static_configs:

        - targets: ['172.16.10.62:9121']
