Linux(CentOS6.5)下修改Nginx初始化配置

本文地址http://comexchan.cnblogs.com/，作者Comex Chan,尊重知识产权，转载请注明出处，谢谢！

首先备份相关文件：

cp /comexHome/nginx/conf/nginx.conf /comexHome/nginx/conf/nginx.conf.bak.comex
cp /comexHome/nginx/conf/mime_types /comexHome/nginx/conf/mime_types.bak.comex
cp /comexHome/nginx/conf/fastcgi_conf /comexHome/nginx/conf/fastcgi_conf.bak.comex
cp /comexHome/nginx/conf/proxy_conf /comexHome/nginx/conf/proxy_conf.bak.comex

然后替换默认配置

cat << EOF >/comexHome/nginx/conf/nginx.conf

最后测试配置文件是否ok

/comexHome/nginx/sbin/nginx –t

下图即为ok：
