ngx_lua 安装,使用

• 验证是否链了luajit

  • linux , ldd

    ldd  `which nginx` | grep lua

  • OSX otool
    • otool -L /usr/local/nginx/sbin/nginx

• 常用命令

  • nginx 修改端口
    • nginx.conf
  • nginx 指定配置文件
    • nginx -c /opt/nginx/conf/nginx.conf 启动时，指定配置文件
    • nginx.conf 会 include mime.types 文件， 所以要把 mime.types 拷贝到新的 配置文件目录。
  • 查看 nginx 配置信息
    • nginx -V
  • nginx 检查修改后的配置的正确性
    • sudo /usr/local/nginx/sbin/nginx -t
  • nginx 重启
    • sudo /usr/local/nginx/sbin/nginx -s reload
  • nginx 停止
    • 1. 查找nginx master 进程
      • ps -ef | grep nginx
    • 2. 平滑关闭
      • sudo kill -QUIT 进程号
  • nginx 日志清理后， 日志不再生成的问题
    • 需要发送 USE1 信号给 nginx master 进程重新打开日志文件

    kill -USR1 `ps axu | grep "nginx: master process" | grep -v grep | awk '{print $2}'`

  • 支持 HTTP Range
    • 配置文件中加入:

    add_header Accept-Ranges bytes; # 断点下载
