1 测试环境nginx服务起不来，提示 Failed to start nginx.service: Unit not found.

原因是： /etc/init.d/目录下面缺少nginx启动文件造成的。

在/etc/init.d/目录下新建nginx文件并写以下代码：

#!/bin/bash
#
# chkconfig: - 85 15
# description: nginx is a World Wide Web server. It is used to serve
# Source Function Library
. /etc/init.d/functions


# Nginx Settings
NGINX_SBIN="/export/servers/nginx/sbin/nginx"
NGINX_CONF="/export/servers/nginx/conf/nginx.conf"
NGINX_PID="/export/servers/nginx/logs/nginx.pid"

RETVAL=0
prog="Nginx"

start() 
        echo -n $"Starting $prog: "
        mkdir -p /dev/shm/nginx_temp
        daemon $NGINX_SBIN -c $NGINX_CONF
        RETVAL=$?
        echo
        return $RETVAL


stop() 
        echo -n $"Stopping $prog: "
        killproc -p $NGINX_PID $NGINX_SBIN -TERM
        rm -rf /dev/shm/nginx_temp
        RETVAL=$?
        echo
        return $RETVAL


reload()
        echo -n $"Reloading $prog: "
        killproc -p $NGINX_PID $NGINX_SBIN -HUP
        RETVAL=$?
        echo
        return $RETVAL


restart()
        stop
        start


configtest()
    $NGINX_SBIN -c $NGINX_CONF -t
    return 0


case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  reload)
        reload
        ;;
  restart)
        restart
        ;;
  configtest)
        configtest
        ;;
  *)
        echo $"Usage: $0 start|stop|reload|restart|configtest"
        RETVAL=1
esac

exit $RETVAL

更改文件权限 sudo chmod 755 nginx
