采用apache的rotatelogs进行按天分割

1. 从一台已经安装好apache的机器上的apache bin目录下把rotatelogs拷贝到本机的/opt/nginx_logs下

   mkdir -p /opt/nginx_logs
   cp rotatelogs /opt/nginx_logs/
   chmod +x /opt/nginx_logs/rotatelogs

2. 创建有名管道

   mkdir /opt/nginx_logs/abc_www/
   mkfifo /opt/nginx_logs/abc_www/access_log

3. 在nginx配置文件server中加上

   access_log /opt/nginx_logs/abc_www/access_log;

4. 创建日志目录

   mkdir /opt/nginx_logs/abc_www/log/

5. 创建日志分割脚本

   [root@localhost nginx_logs]# cat /opt/nginx_logs/abc_www/rotate.sh
   baselogdir=/opt/nginx_logs/abc_www
   rotatelogs=/opt/nginx_logs/rotatelogs
   while [ 1 ]
   do
   echo `date +"%F %T"`" rotatelogs access start"
   $rotatelogs $baselogdir/log/access_%Y%m%d.log 86400 480 < $baselogdir/access_log
   echo `date +"%F %T"`" rotatelogs access stop"
   sleep 1;
   done

6. 创建启动日志分割脚本

   [root@localhost nginx_logs]# cat /opt/nginx_logs/abc_www/run.sh
   sh /opt/nginx_logs/abc_www/rotate.sh >> /opt/nginx_logs/abc_www/log/access-rotate.log 2>&1 &

Nginx反向代理映射成子路径

多个web应用共享一个域名和端口时，可以考虑把不同的web应用映射成不同的子路径，这个子路径在Java EE里称作ContextPath。下面的配置片段解决nginx作为前端，反向代理多个tomcat主机，通过不同子路径共享一个域名的情况。

server {
    listen       80;
    server_name  _;
    index index.html index.htm index.php;
    root /home/dashboard;

    location /dashboard {
        rewrite /dashboard/(.*) /$1 break;
        rewrite ^/dashboard$ /dashboard/ permanent;
        proxy_pass http://127.0.0.1:9082;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

子目录跳转：

upstream abc{
        server 127.0.0.1:8000;
}

server {
  listen  80;

  server_name abc.com;

gzip on;
gzip_http_version 1.0;
gzip_comp_level 3;
gzip_types text/plain application/x-javascript text/css application/xml;

 location ~ .*\.(?:ico|css|js|gif|jpe?g|png|html)$ {
        proxy_pass http://abc;
        expires 30d;
 }

  location / {
        rewrite /(.*)$ /player/$1 break;
        proxy_pass http://abc;
  }

  error_page   500 502 503 504  /50x.html;
  error_page   404  /404.html;
  location = /50x.html {
    root   html;
  }
  location = /404.html {
    root   /mnt/website/abc;
  }

}
