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

/etc/init.d/nginx start
/etc/init.d/nginx stop

[root@iZ2ze7dyjfik9i0bgl5o1cZ bin]# /etc/init.d/nginx start
-bash: /etc/init.d/nginx: /bin/sh^M: bad interpreter: No such file or directory

首先要确保文件有可执行权限：
cd /etc/init.d/
chmod a+x nginx然后修改文件格式:
vim nginx利用如下命令查看文件格式 :set ff 或 :set fileformat 

可以看到如下信息 fileformat=dos 或 fileformat=unix 

利用如下命令修改文件格式 :set ff=unix 或 :set fileformat=unix 

:wq (存盘退出)
