Centos7.x下haproxy注册成服务的教程

1.尝试在   usr/lib/systemd/system/下新建haproxy.service,始终不行，网上也没有出现这种方法
2.尝试第二种方法，在etc/init.id/ 创建haproxy，编写脚本如下：

#!/bin/bash

#

# haproxy

#

# chkconfig: 35 85 15

# description: HAProxy is a free, very fast and reliable solution

# offering high availability, load balancing, and

# proxying for TCP and HTTP-based applications

# processname: haproxy

# config: /etc/haproxy.cfg

# pidfile: /var/run/haproxy.pid

# Source function library.

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

# Source networking configuration.

. /etc/sysconfig/network

# Check that networking is up.

[ "$NETWORKING" = "no" ] && exit 0

config="/usr/app/haproxy/etc/haproxy.cfg"

exec="/usr/app/haproxy/sbin/haproxy"

prog=$(basename $exec)

[ -e /etc/sysconfig/$prog ] && . /etc/sysconfig/$prog

lockfile=/var/lock/subsys/haproxy

check() {

    $exec -c -V -f $config

}

start() {

    $exec -c -q -f $config

    if [ $? -ne 0 ]; then

        echo "Errors in configuration file, check with $prog check."

        return 1

    fi

    echo -n $"Starting $prog: "

    # start it up here, usually something like "daemon $exec"

    daemon $exec -D -f $config -p /var/run/$prog.pid

    retval=$?

    echo

    [ $retval -eq 0 ] && touch $lockfile

    return $retval

}

stop() {

    echo -n $"Stopping $prog: "

    # stop it here, often "killproc $prog"

    killproc $prog

    retval=$?

    echo

    [ $retval -eq 0 ] && rm -f $lockfile

    return $retval

}

restart() {

    $exec -c -q -f $config

    if [ $? -ne 0 ]; then

        echo "Errors in configuration file, check with $prog check."

        return 1

    fi

    stop

    start

}

reload() {

    $exec -c -q -f $config

    if [ $? -ne 0 ]; then

        echo "Errors in configuration file, check with $prog check."

        return 1

    fi

    echo -n $"Reloading $prog: "

    $exec -D -f $config -p /var/run/$prog.pid -sf $(cat /var/run/$prog.pid)

    retval=$?

    echo

    return $retval

}

force_reload() {

    restart

}

fdr_status() {

    status $prog

}

case "$1" in

    start|stop|restart|reload)

        $1

        ;;

    force-reload)

        force_reload

        ;;

    checkconfig)

        check

        ;;

    status)

        fdr_status

        ;;

    condrestart|try-restart)

      [ ! -f $lockfile ] || restart

    ;;

    *)

        echo $"Usage: $0 {start|stop|status|checkconfig|restart|try-restart|reload|force-reload}"

        exit 2

esac
