1、定義和初始化函數(shù)：

bool Init(std::string ip);

1.1、獲取ip地址，這里的ip地址是通過makefile文件直接設定的。

bool XAgent::Init(string ip)
{
    if (ip.empty())
    {
        cerr << "Agent::init failed! ip is empty" << endl;
        return false;
    }
}

1.2、調用動態(tài)鏈接庫，這里的LXMysql是前面文章中講過的

my = new LXMysql();

1.3、連接數(shù)據庫，這里的Connect函數(shù)見 之前講的這篇文章https://blog.csdn.net/wjl990316fddwjl/article/details/135379309

#ifdef _WIN32
    if (!my->Connect(ip.c_str(), "root", "990107Wjl@", "database_test"))
    {
        cerr << "Agent::init failed! Connect DB failed!" << endl;        
        return false;
    }
#else   
    //LINUX
    if (!my->Connect(ip.c_str(), "fdd", "990107Wjl@", "test_fdd"))
    {
        cerr << "Agent::init failed! Connect DB failed!" << endl;
        return false;
    }
#endif //!_WIN32

bool LXMysql::Connect(const char* host, const char* user, const char* password, const char* database, unsigned short port, unsigned short flag)
	{

		if (!Init())//防止內存泄露
		{
			cerr << "Connect faivertgled,mysql is not init!" << endl;
			return false;
		}
		if (!mysql_real_connect(mysql, host, user, password, database, port, 0, flag))
		{
			cerr << "mysql_real_connect failed!" << mysql_error(mysql) << endl;
			return false;
		}
		cout << "mysql connect success!" << endl;
		return true;
	}

1.4、日志文件地址

//日志的路徑
#define LOGPATH "/var/log/auth.log"

1.5、 測試日志是否存在

//讀取日志文件
    fp = fopen(LOGPATH, "rb");
    if (!fp)
    {
        cerr << "open" << LOGPATH << "failed" << endl;
        return false;
    }
    cout << "open" << LOGPATH << "success" << endl;

1.5、測試連接初始化

int main(int argc,char *argv[])
{
    //agrc當前執(zhí)行路徑
    if (argc < 2)
    {
        cout << "please set ip" << endl;
        cout << "./agent 192.168.122.128" << endl;
        return false;
    }
    //1、初始化agent 連接數(shù)據庫
    if (!XAgent::Get()->Init(argv[1]))
    {
        //!XAgent::Get()->Init()通過::Get()訪問靜態(tài)函數(shù)，靜態(tài)函數(shù)來調用Init(),
        cout << "agent Init failed!" << endl;
        return -1;
    }
    cout << "Agent Start!" << endl;
    std::cout << "Hello World!\n";
}

完結，下一篇主要是讀取日志文件，并讀取最新日志文件文章來源地址http://www.zghlxwxcb.cn/news/detail-794696.html
