我正在使用fc19,刚才我已经安装了syslog-ng。看起来syslog不再适用于fc19。我启动了syslog-ng服务。 syslog-ng的状态正在运行。这是我的计划。我不记录输出的位置。
#include<iostream>
#include<ctime>
#include<syslog.h>
#include <unistd.h>
using namespace std;
class my_syslog
{
private:
int m_sys;
public:
my_syslog(int init);
void get_time();
};
my_syslog::my_syslog(int init):m_sys(init)
{
cout<<"Constructor called"<<endl;
}
void my_syslog::get_time()
{
time_t now = time(0);
tm* localtm = localtime(&now);
//cout << "SJ:The local date and time is: " << asctime(localtm) << endl;
// Convert now to tm struct for UTC
//tm* gmtm = gmtime(&now);
//if (gmtm != NULL) {
//cout << "The UTC date and time is: " << asctime(gmtm) << endl;
//}
syslog (LOG_INFO, "SJ:The local date and time is: %s",asctime(localtm));
}
int main(int argc, char **argv)
{
my_syslog instant(100);
for(int i = 0; i<=10;i++)
{
instant.get_time();
sleep(10);
}
cout<<"Program End"<<endl;
return 0;
}
/etc/syslog-ng/syslog-ng.conf如下。
@version:3.3

# This should behave pretty much like the original syslog on RedHat. But
# it could be configured a lot smarter.
#
# See syslog-ng(8) and syslog-ng.conf(5) for more information.
#
# Note: it also sources additional configuration files (*.conf)

在使用syslog()
之前,您需要openlog()
。
