linux启动错误:lldpad: config file failed to load

1. 查看lldpad信息:man lldpad(不存在时创建该文件) /conf --->定位OPTIONS

       lldpad has the following command line options:
   
       -h     show usage information
   
       -f filename
              use  the specified file as the configuration file instead of the
              default file:  /var/lib/lldpad/lldpad.conf  lldpad  expects  the
              directory of the configuration file to exist, but if the config‐
              uration file does not exist, then a default  configuration  file
              will  be  created.  lldpad creates and maintains the contents of
              the configuration file.  Configuration should  be  performed  by
              using lldptool or dcbtool.
        ...
   

2. 使用locate lldpad|grep conf不存在该文件
3. 输入lldpad产生lldpad.conf,
4. find /var/log -type f -exec rm -v {}\; //delete log info
5. find /var/log -type f|xargs grep failed 然仍然不能去除该错误. /var/log/messages:Feb 19 09:13:28 door2 lldpad: config file failed to load,

6. google --lldpad: config file failed to load help me in https://github.com/openSUSE/lldpad/blob/master/config.c code:

   /*
   * init_cfg - initialze the global lldpad_cfg via config_init
   *
   * Returns true (1) for succes and false (0) for failed

   */
    int init_cfg(void)
    {
            const char *p;
            int err = 1;
   
            config_init(&lldpad_cfg);
   
            if (check_cfg_file()) {
                err = 0;
                LLDPAD_INFO("%s: failed to create config file\n", __func__);
            } else if (!config_read_file(&lldpad_cfg, cfg_file_name)) {
                err = 0;
                LLDPAD_INFO("%s: config file failed to load\n", __func__);
            } else if (config_lookup_string(&lldpad_cfg, "version", &p)) {
                LLDPAD_INFO("%s: config file version incorrect ", __func__);
                LLDPAD_INFO("rebuild file with correct version.\n");
                destroy_cfg();
                remove(cfg_file_name);
                if (check_cfg_file() ||
                    !config_read_file(&lldpad_cfg, cfg_file_name))
                    err = 0;
            }
            return err;
    }
   

7. ll /var/lib/lldpad/lldpad.conf -rw-------. 1 root root 587 11月 19 00:23 /var/lib/lldpad/lldpad.conf

8. chmod 644 lldpad.conf
