linux service启动添加nginx

linux系统的service启动 是基于shell脚本运行的。
如要加入service管理启动 ，将启动的脚本统一放入 /etc/init.d 下。如：nginx

#!/bin/bash
#nginx Startup script for the Nginx HTTP Server
#it is v.0.0.2 version.
#chkconfig: - 85 15
#description: Nginx is a high-performance web and proxy server.
#It has a lot of features, but it’s not for everyone.
#processname: nginx
#pidfile: /var/run/nginx.pid
#config: /usr/local/nginx/conf/nginx.conf

nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_pid=/var/run/nginx.pid
RETVAL=0
prog=“nginx”
#Source function library.

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

#Source networking configuration.

. /etc/sysconfig/network
#Check that networking is up.

[ ${NETWORKING} = “no” ] && exit 0

[ -x $nginxd ] || exit 0

#Start nginx daemons functions.

start() {

if [ -e $nginx_pid ];then

echo “nginx already running…”
exit 1

fi

echo -n $"Starting $prog: "
daemon $nginxd -c ${nginx_config} RETVAL=$?
echo

[ $RETVAL = 0 ] && touch /var/lock/subsys/nginx

return $RETVAL

}

#Stop nginx daemons functions.
stop() {

    echo -n $"Stopping $prog: "
    killproc $nginxd
    RETVAL=$?
    echo
    [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid

}

#reload nginx service functions.
reload() {
echo -n $"Reloading $prog: "
#kill -HUP cat ${nginx_pid}
killproc $nginxd -HUP RETVAL=$?
echo

}

#See how we were called.
