【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
