nginx启动失败：Redirecting to /bin/systemctl restart nginx.service Failed to restart nginx.service: Unit nginx.service not found.

 

 解决：在/etc/init.d/下创建nginx文件作启动脚本

#!/bin/bash
#
# chkconfig: - 85 15
# description: Nginx is a World Wide Web server.
# processname: nginx

nginx=/usr/local/nginx/sbin/nginx
conf=/usr/local/nginx/conf/nginx.conf
case $1 in
start)
echo -n "Starting Nginx"
$nginx -c $conf
echo " done"
;;
stop)
echo -n "Stopping Nginx"
killall -9 nginx
echo " done"
;;
test)
$nginx -t -c $conf
;;
reload)
echo -n "Reloading Nginx"
ps auxww | grep nginx | grep master | awk '{print $2}' | xargs kill -HUP
echo " done"
;;
restart)
$0 stop
$0 start
;;
show)
ps -aux|grep nginx
;;
*)
echo -n "Usage: $0 {start|restart|reload|stop|test|show}"
;;
esac

注意，保存一定要保存成UNIX格式（notepad++：编辑–文档格式转换–转为UNIX格式），否则会报错。

设置执行权限：chmod +x /etc/init.d/nginx
注册成服务：chkconfig --add nginx
设置开机启动：chkconfig nginx on

之后，就可以使用以下命令了
service nginx start
service nginx stop
service nginx restart
service nginx reload
