1：nginx配置文件，nginx路径根据自己安装的位置而修改  vim /etc/init.d/nginx

#! /bin/bash
#chkconfig: 2345 80 90
#description:nginx run

# nginx启动脚本

PATH=/data/soft/nginx
DESC="nginx daemon"
NAME=nginx
DAEMON=$PATH/$NAME
CONFIGFILE=$PATH/$NAME.conf
PIDFILE=$PATH/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
set -e
[ -x "$DAEMON" ] || exit 0
do_start()
{
    $DAEMON -c $CONFIGFILE || echo -n "nginx already running"
}
do_stop()
{
    $DAEMON -s stop || echo -n "nginx not running"
}
do_reload()
{
    $DAEMON -s reload || echo -n "nginx can't reload"
}
case "$1" in
    start)
        echo -n "Starting $DESC: $NAME"
        do_start
        echo "."
    ;;
    stop)
        echo -n "Stopping $DESC: $NAME"
        do_stop
        echo "."
    ;;
    reload|graceful)
        echo -n "Reloading $DESC configuration..."
        do_reload
        echo "."
    ;;
    restart)
        echo -n "Restarting $DESC: $NAME"
        do_stop
        do_start
        echo "."
    ;;
    *)
        echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2
        exit 3
    ;;
esac
exit 0

2：设置执行权限

chmod a+x /etc/init.d/nginx

3：注册成服务

chkconfig --add nginx

4：设置开机启动

chkconfig nginx on

5：重启, 查看nginx服务是否自动启动

shutdown -h 0 -r

ps -ef | grep nginx

6：对nginx服务执行停止/启动/重新读取配置文件操作

启动
systemctl start nginx.service

重载
systemctl reload nginx.service

停止
systemctl top nginx.service

重启
systemctl restart nginx.service
