把Nginx加为系统服务(service nginx start/stop/restart)

1、编写脚本，名为nginx

#!/bin/sh 
# 
# nginx - this script starts and stops the nginx daemon 
# 
# chkconfig:   - 85 15 
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \ 
#               proxy and IMAP/POP3 proxy server 
# processname: nginx 
# config:      /etc/nginx/nginx.conf 
# config:      /etc/sysconfig/nginx 
# pidfile:     /var/run/nginx.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 

nginx="/usr/local/nginx/sbin/nginx" 
prog=$(basename $nginx) 

NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf" 

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx 

lockfile=/var/lock/subsys/nginx 

start() { 
    [ -x $nginx ] || exit 5 
    [ -f $NGINX_CONF_FILE ] || exit 6 
    echo -n $"Starting $prog: " 
    daemon $nginx -c $NGINX_CONF_FILE 
    retval=$? 
    echo 
    [ $retval -eq 0 ] && touch $lockfile 
    return $retval 
} 

stop() { 
    echo -n $"Stopping $prog: " 
    killproc $prog -QUIT 
    retval=$? 
    echo 
    [ $retval -eq 0 ] && rm -f $lockfile 
    return $retval 
killall -9 nginx 
} 

restart() { 
    configtest || return $? 
    stop 
    sleep 1 
    start 
} 

reload() { 
    configtest || return $? 
    echo -n $"Reloading $prog: " 
    killproc $nginx -HUP 
RETVAL=$? 
    echo 
} 

force_reload() { 
    restart 
} 

configtest() { 
$nginx -t -c $NGINX_CONF_FILE 
} 

rh_status() { 
    status $prog 
} 

rh_status_q() { 
    rh_status >/dev/null 2>&1 
} 

case "$1" in 
    start) 
        rh_status_q && exit 0 
    $1 
        ;; 
    stop) 
        rh_status_q || exit 0 
        $1 
        ;; 
    restart|configtest) 
        $1 
        ;; 
    reload) 
        rh_status_q || exit 7 
        $1 
        ;; 
    force-reload) 
        force_reload 
        ;; 
    status) 
        rh_status 
        ;; 
    condrestart|try-restart) 
        rh_status_q || exit 0 
            ;; 
    *)    
      echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}" 
        exit 2 
esac

[root@example ~]# cp nginx /etc/init.d/
[root@example ~]# chmod 755 /etc/init.d/nginx
[root@example ~]# chkconfig --add nginx

3、nginx启动、停止、无间断服务重启

[root@example ~]# service nginx start

[root@example ~]# service nginx stop

[root@example ~]# service nginx reload

完毕我想应该也可以按照此方法添加其他的服务。
