[Linux] su: cannot set user id: Resource temporarily unavailable

今天ssh mysql db 测试服务器,进去切换成Mysql帐号报错如下:


登陆mysql报错如下:

[xxx@xxx-c003db2 ~]$ mysql -uroot -
ERROR 1135 (HY000): Can't create a new thread (errno 11); if you are not out of available memory, you can consult the manual for a possible OS-dependent bug


切换进mysql用户进去检查:

[xxx@xxx-c001db2 mysqldata]$ sudo su - mysql
su: cannot set user id: Resource temporarily unavailable



经过检查,确定是mysql有一个目录/data/磁盘满了,测试服务器是虚拟机,所以让sa给/data/目录增加了100M空间之后,就可以sudo su 进去了:




[xxx@xxx-c001db2 mysqldata]$ sudo su - mysql
[mysql@xxx-c001db2 ~]$


[mysql@xxx-c001db2 ~]$ df -h

呵呵,赶紧去清理磁盘上爆发增长的binlog日志吧,今天tester在做高并发测试。
