在 nginx.conf 中，增加以下内容：
server {
listen 7070;
server_name localhost;
location /report.html {
alias /home/huangjian/local/nginx/www/html/;
index report.html;
}
}
打开浏览器访问：localhost:7070/report.html
如果是在服务器上，可以用 ssh 把端口 7070 映射到本地电脑。
root 的处理结果是：root 路径 ＋ location 路径
alias 的处理结果是：使用 alias 路径替换 location 路径
还有一个重要的区别是 alias 后面必须要用 “/” 结束，否则会找不到文件的，而 root 则可有可无。
location ^~ /a/ {
root /home/huangjian/local/nginx/www/html;
}
如果一个请求的 URI 是 /a/index.html 时，web 服务器将会返回服务器上的 /home/huangjian/local/nginx/www/html/a/index.html 的文件。
location ^~ /b/ {
alias /home/huangjian/local/nginx/www/html/alias_dir/;
}
如果一个请求的 URI 是 /b/index.html 时，web 服务器将会返回服务器上的 /home/huangjian/local/nginx/www/html/alias_dir/index.html 的文件。
#!/bin/bash
#Rotate the Nginx logs
logs_path=/home/huangjian/local/openresty/nginx/logs #Nginx 的日志目录
backup_path=${logs_path}/history #Nginx 日志的备份目录
expire_backup_delete="ON" #是否开启过期备份删除 ON为开启 OFF为关闭
expire_days=3 #过期时间天数 默认为三天，此项只有在expire_backup_delete开启时有效
if [ ! -d ${backup_path} ]; then
mkdir -p ${backup_path}
fi
YESTERDAY=$(date -d "yesterday" +%Y-%m-%d)
mv ${logs_path}/access.log ${backup_path}/access_${YESTERDAY}.log
mv ${logs_path}/error.log ${backup_path}/error_${YESTERDAY}.log
# send signal USR1 to Nigix master process, to reopen logs.
kill -USR1 $(cat ${logs_path}/nginx.pid)
if [ "$expire_backup_delete" == "ON" -a "$backup_path" != "" ]; then
`find $backup_path/ -type d -mtime +$expire_days | xargs rm -rf`
fi
logs_path 目录和 backup_path 目录需要在同一个硬盘下。因为 mv 的时候，只有在同一个硬盘下，log 文件的 inode 才不会改变，这样日志才不会丢失。
