mysql在阿里云崩溃的问题

mysql在 阿里云 崩溃 自动关闭了 搜索后又不少类似的问题日志如下 140211 14:40:41 mysqld_safe Number of processes running now: 0 140211 14:40:41 mysqld_safe mysqld restarted 140211 14:40:41 InnoDB: The InnoDB memory heap is disabled 140211 14:40:41 InnoDB: Mutexes and rw_locks use GCC atomic builtins 140211 14:40:41 InnoDB: Compressed tables use zlib 1.2.3 140211 14:40:41 InnoDB: Initializing buffer pool, size = 128.0M InnoDB: mmap(137363456 bytes) failed; errno 12 140211 14:40:41 InnoDB: Completed initialization of buffer pool 140211 14:40:41 InnoDB: Fatal error: cannot allocate memory for the buffer pool 140211 14:40:41 [ERROR] Plugin 'InnoDB' init function returned error. 140211 14:40:41 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 140211 14:40:41 [ERROR] Unknown/unsupported storage engine: InnoDB 140211 14:40:41 [ERROR] Aborting 140211 14:40:41 [Note] /usr/local/mysql/bin/mysqld: Shutdown complete 140211 14:40:42 mysqld_safe mysqld from pid file /data/mysql/localhost.localdomain.pid ended 本机没使用innodb，感觉和内存有关，阿里云是建立不要创建swap的 ，个人感觉是内存不够调用不到swap导致的，猜测而已 自己先建立一个swap重启后正常运行。 添加swap分区的步骤: 1) dd if=/dev/zero of=/var/swapfile bs=1M count=1024 2) mkswap /var/swapfile 3) swapon /var/swapfile 4) 添加这行： /var/swapfile swap swap defaults 0 0 到 /etc/fstab 运行7天没有关闭，还有待观察观察！
