设置core文件路径


1 设置 vi /etc/sysctl.conf kernel.core_pattern=/home/allcores/core-%e-%p-%s-%t sysctl -p 在home目录下创建allcores文件夹 附上core文件支持的格式列表: %p – insert pid into filename 【pid】 %u – insert current uid into filename 【uid】 %g – insert current gid into filename 【gid】 %s – insert signal that caused the coredump into the filename 【core信号】 %t – insert UNIX time that the coredump occurred into filename 【core文件生成时的unix时间】 %h – insert hostname where the coredump happened into filename 【主机名】 %e – insert coredumping executable name into filename 【应用的名字 2 确认 more /proc/sys/kernel/core_pattern查看是否修改成功 3 测试 #include <stdio.h> #include <stdlib.h> #include <sys/time.h> #include <sys/resource.h> int main() {         struct rlimit rl;         rl.rlim_cur = RLIM_INFINITY;         rl.rlim_max = RLIM_INFINITY;         setrlimit(RLIMIT_CORE,&rl);         int i = 0;         int *p = &i;         p = NULL;         i = *p;         printf("%s", p);         printf("printf success!\n");         return 0; }
