前提:安装好nginx,如果已经启动nginx,先停止,命令:

./usr/local/nginx/sbin/nginx -s stop

修改nginx配置

vi /usr/local/nginx/conf/nginx.conf  

配置好以后的nginx.conf文件内容:

#user  nobody;
worker_processes 1; #error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info; #pid logs/nginx.pid; events {
