【八】将日志写入log(glog)

【任务8】将日志写入log(glog)

glog简介

glog是google开源的一个日志系统,相比较log4系列的日志系统，它更加轻巧灵活，而且功能也比较完善

glog配置使用资料

下载glog

  • 命令：git clone https://github.com/google/glog.git

  • 如果没有git命令：yum -y install git

编译glog

  • 进入glog目录，打开README文件，按照其中的提示步骤进行编译：./autogen.sh && ./configure && make && make install

  • 完成后，会在/usr/local/lib路径下看到libglog*一系列库

Makefile文件和RecSys_server.skeleton.cpp文件

  • 修改之前在gen-cpp目录中的Makefile文件,在LIBS变量的末尾加上-lglog:LIBS = -L/usr/local/lib/*.so -lthrift -lfcgi -lglog

  • 修改gen-cpp目录中RecSys_server.skeleton.cpp文件:

      #include "RecSys.h"
  #include <thrift/protocol/TBinaryProtocol.h>
  #include <thrift/server/TSimpleServer.h>
  #include <thrift/transport/TServerSocket.h>
  #include <thrift/transport/TBufferTransports.h>

  //添加头文件
  #include <glog/logging.h>

  using namespace ::apache::thrift;
  using namespace ::apache::thrift::protocol;
  using namespace ::apache::thrift::transport;
  using namespace ::apache::thrift::server;

  using boost::shared_ptr;

  class RecSysHandler : virtual public RecSysIf {
  public:
      RecSysHandler() {
          // Your initialization goes here
      }

      void rec_data(std::string& _return, const std::string& data) {
          // Your implementation goes here
          printf("=======================\n");
          std::cout << "receive client data:" << data << std::endl;
          
          std::string ack = "yeah,I love you too!!";
          
          //log输出，使用时按情况选择
          LOG(INFO) << data;
          LOG(ERROR) << data;
          LOG(WARNING) << data;

          _return = ack;
      }

      };

      int main(int argc, char **argv) {
      
      google::InitGoogleLogging(argv[0]);	

      int port = 9090;
      shared_ptr<RecSysHandler> handler(new RecSysHandler());
      shared_ptr<TProcessor> processor(new RecSysProcessor(handler));
      shared_ptr<TServerTransport> serverTransport(new TServerSocket(port));
      shared_ptr<TTransportFactory> transportFactory(new TBufferedTransportFactory());
      shared_ptr<TProtocolFactory> protocolFactory(new TBinaryProtocolFactory());

      TSimpleServer server(processor, serverTransport, transportFactory, protocolFactory);
      server.serve();
      return 0;
  }

重新编译client端和server端

  • kill掉之前的client和server，在make相应的client和server

  • 再次启动server端和client，命令：./server,/usr/local/src/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 8088 -f /test/thrift_test/python_thrift_demo/gen-cpp/client

  • 同上操作，用浏览器的方式访问，server端会打印出log，并产生log日志文件，默认路径：/tmp/下的server.ERROR,server.INFO,server.WARNING

  • 更改glog产生log日志文件的路径，在gen-cpp目录下的RecSys_server.skeleton.cpp文件中的int main()方法中添加代码，添加glog输出地址：

int main(int argc, char **argv) {

//glog地址
FLAGS_log_dir = "/test/thrift_test/python_thrift_demo/gen-cpp/logs"
google::InitGoogleLogging(argv[0]);	

int port = 9090;
shared_ptr<RecSysHandler> handler(new RecSysHandler());
shared_ptr<TProcessor> processor(new RecSysProcessor(handler));
shared_ptr<TServerTransport> serverTransport(new TServerSocket(port));
shared_ptr<TTransportFactory> transportFactory(new TBufferedTransportFactory());
shared_ptr<TProtocolFactory> protocolFactory(new TBinaryProtocolFactory());

TSimpleServer server(processor, serverTransport, transportFactory, protocolFactory);
server.serve();
return 0;
}

其中logs目录需要自行创建

  • 然后执行make命令，重新生成client端和server端
