启用--skip-name-resolve参数的话，就不能用主机名直接连接了，把用户里的带AY1308162201443403e0Z的删除，删除前要确保有127.0.0.1的

但是这个问题不会导致mysql挂掉

nginx日志里只是显示php-fpm挂了，具体原因要看php-fpm日志或开启slowlog看

superman

昨天晚上从凌晨两点开始又挂了，cpu一直都是100%
查看php-fpm.log  cpu100%的时间段没有任何记录
nginx_error.log里面的日志也是这个时间段没有任何记录
求助下军哥我该怎么找到问题的所在？现在站一开，一会就cpu100%了，而且找不到记录，谢谢军哥了
