Linux下创建nginx脚本-start、stop、reload…

1、关闭nginx
利用ps -aux | grep nginx 查看nginx是否启动 如果启动了就kill杀死
2、创建/etc/init.d/nginx文件

root@dnnp:~/software/nginx-1.2.3# vim /etc/init.d/nginx

3、添加权限并启动

root@dnnp:~/software/nginx-1.2.3# chmod +x /etc/init.d/nginx
root@dnnp:~/software/nginx-1.2.3# /etc/init.d/nginx start
starting nginx: nginx.
root@dnnp:~/software/nginx-1.2.3# ps -aux | grep nginx
warning: bad ps syntax, perhaps a bogus '-'? see http://procps.sf.net/faq.html
root   25078 0.0 0.0  4596  700 ?    ss  14:20  0:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody  25079 0.0 0.1  4820 1056 ?    s  14:20  0:00 nginx: worker process
root   25081 0.0 0.0  3304  768 pts/0  s+  14:20  0:00 grep nginx
root@dnnp:~/software/nginx-1.2.3#

注：/etc/init.d/nginx文件内容如下

#! /bin/sh
 
### begin init info

# required-stop:   $all
# default-start:   2 3 4 5

# include nginx defaults if available
