1.启动MySQL时一直不成功,查看错误日志 /var/log/mysql/error.log
2.主要的错误信息有如下几条:
[ERROR] InnoDB: mmap(136151040 bytes) failed; errno 12 [ERROR] InnoDB: Cannot allocate memory for the buffer pool [ERROR] InnoDB: Plugin initialization aborted with error Generic error [ERROR] Plugin 'InnoDB' init function returned error. [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. [ERROR] Failed to initialize plugins. [ERROR] Aborting
3.查询后是因为内存不足,查看内存
增加swap交换空间解决问题:
dd if=/dev/zero of=/swapfile bs=1M count=1024 mkswap /swapfile swapon /swapfile
4.增加自动挂载:
在文件/etc/fstab中加入 /swapfile swap swap defaults 0 0
service mysql start
启动成功
