前言

背景：常常需要将 二进制文件打包成 rpm 包， 以便其他人安装使用或上传 yum 源。本文包含两部分内容，二进制包制作 rpm，以service方式运行。
文件说明：
/usr/bin/gocron-node：二进制文件
/opt/gocron-node/start.sh： service启动脚本
/opt/gocron-node/stop.sh： service停止脚本
/etc/gocron-node/gocron.conf：二进制执行配置文件
/etc/init.d/gocron：service脚本

spec 文件

首先，需要将二进制及需要的其他启动脚本放在一个目录下，目录的命名规则以"Name-Version-Release.arch"方式命名，arch为机器的架构，如本人是 X86_64。名字和spec里必须对应。撰写spec文件，由于是二进制打包，无源码也就没有build过程，本人的二进制没有安装依赖，也没写。源码打包可参看博客 制作rpm ，主要涉及 install 和 file

编写启动停止脚本(自行修改)

建议编写脚本，处理进程已存在和停止的一些逻辑

#!/bin/bash
# start.sh
conf=$1
PIDFILE=$2
if [[ $PIDFILE == "" ]];then
        PIDFILE="/var/run/gocron-node.pid"
fi

oldPid=`pidof gocron-node`
if [[ $oldPid != "" ]];then
        echo "[info]  gocron-node is active, do nothing..."
        exit 0
fi

while read line
do
        if [[ `echo $line | grep -v "#"` ]];then
                port=$line
                break
        fi
done < $conf
port=`echo $port | awk -F '=' '{print $2}'`

function isPositiveInt () {

  if [[ ${1} =~ ^[0-9]*[1-9][0-9]*$ ]]; then
        return 1
  fi

  return 0
}

isPositiveInt $port
returnValue=$?
if [[ $returnValue -eq 0 ]];then
        port=5921
fi

echo "[info]  Your custom port: $port"
gocron-node -allow-root true -s 0.0.0.0:$port &
exitCode=$?

pid=`pidof gocron-node`
echo $pid > "$PIDFILE"
exit $exitCode

#!/bin/bash
# stop.sh

info=`netstat -nlp | grep gocron`

gocronPid=`pidof gocron-node`

if [[ $gocronPid == "" ]];then
        exit 0
else
        echo "[info]  Gocron pid:[$gocronPid]."
        /bin/kill $gocronPid
        exit $?
fi

编写service

为了兼容，使用 /etc/init.d下的方式来编写，也可以使用 systemd编写服务，可自行谷歌。此脚本需编写start，stop，restart等模块。本人参考 hadoop-yarn-manager 撰写。开头使用了service系统调用，详情可参考这篇 博客

. /lib/lsb/init-functions
CONF_PATH="/etc/gocron-node/gocron.conf"
EXEC_DIR="/opt/gocron-node"
SLEEP_TIME=3
RETVAL=0
DESC="Go crontab node"
STATUS_RUNNING=0
RETVAL_SUCCESS=0
PROC_NAME='gocron-node'
PIDFILE="/var/run/gocron-node.pid"

STATUS_RUNNING=0
STATUS_DEAD=1
STATUS_DEAD_AND_LOCK=2
STATUS_NOT_RUNNING=3

start() {
  echo "[info]  Default port: 5921, custom by changing $CONF_PATH"
  /bin/bash $EXEC_DIR/start.sh $CONF_PATH $PIDFILE

  # Some processes are slow to start
  sleep $SLEEP_TIME
  checkstatusofproc
  RETVAL=$?

  if [ $RETVAL -eq $STATUS_RUNNING ]; then
        log_success_msg "[info]  Started ${DESC}: "
  else
        log_failure_msg "[err ]  Failed to start ${DESC}. Return value: $RETVAL"
  fi
  return $RETVAL
}


stop() {
  /bin/bash $EXEC_DIR/stop.sh
  RETVAL=$?

  if [ $RETVAL -eq $RETVAL_SUCCESS ]; then
         log_success_msg "[info]  Stopped ${DESC}: "
  else
         log_failure_msg "[err ]  Failed to stop ${DESC}. Return value: $RETVAL."
  fi
}
restart() {
  stop
  start
}

checkstatusofproc(){
  pidofproc -p $PIDFILE $PROC_NAME > /dev/null
}

checkstatus(){
  checkstatusofproc
  status=$?

  case "$status" in
    $STATUS_RUNNING)
      log_success_msg "[info]  ${DESC} is running"
      ;;
    $STATUS_DEAD)
      log_failure_msg "[info]  ${DESC} is dead and pid file exists"
      ;;
    $STATUS_DEAD_AND_LOCK)
      log_failure_msg "[info]  ${DESC} is dead and lock file exists"
      ;;
    $STATUS_NOT_RUNNING)
      log_failure_msg "[info]  ${DESC} is not running"
      ;;
    *)
      log_failure_msg "[info]  ${DESC} status is unknown"
      ;;
  esac
  return $status
}

check_for_root() {
  if [ $(id -ur) -ne 0 ]; then
    echo '[err ]  Error: root user required'
    echo
    exit 1
  fi
}
service() {
  case "$1" in
    start)
      check_for_root
      start
      ;;
    stop)
      check_for_root
      stop
      ;;
    status)
      checkstatus
      RETVAL=$?
      ;;
    restart)
      check_for_root
      restart
      ;;
    *)
      echo $"[info]  Usage: $0 {start|stop|status|restart}"
      exit 1
  esac
}

service "$@"

exit $RETVAL

编译执行

编译spec文件，启动服务

rpmbuild -bb gnode.spec  #编译
rpm -ivh xxxx.rpm        #安装
# rpm -e xxx             #卸载
service gocron start     #启动

看似简单几步，却过程相对复杂。
