mysql报错mmap(137428992 bytes) failed; errno 12,Cannot allocate memory for the buffer pool

mysql以`systemctl start mysqld.service`的方式启动一段时间后发现突然无法启动，尝试重新启动也不能解决问题，排查问题时，先后通过`systemctl status mysqld.service`和`journalctl -xe` 命令查看问题，无所得.然后查看`/var/log/mysqld.log`发现日志内报错信息如下:

网上查阅资料，有人说是 swap不够了，使用`free`命令查看发现空余swap确实为0,但很奇怪，我买的vultr和ecs使用`free`看到的空余的swap都是0，那么为什么vultr部署的mysql服务挂掉了，ecs的没有挂掉呢? 后来使用命令`sudo dd if=/dev/zero of=/swapfile bs=1M count=1024` 增加swap发现不起作用,我的空余swap仍然是0。

又查阅资料，有人说修改`my.cnf`里，将`innodb_buffer_pool_size` 注释打开，然后重启服务，发现还是报错.

后来将我的`my.cnf` 里的`innodb_buffer_pool_size= 64M`调低到64M，然后重启服务，mysql启动成功。

总结: 可能是我的服务器配置较低，使得mysql5.7正常的 `Initializing buffer pool=128`无法分配成功，降低其配置即可以。

一.mysql 的bin目录下有个MySQLInstanceConfig.exe,运行就可以进行创建数据库实例,创建实例时也可以生成windows 服务,把服务设置成自动启动就可以了 二.安装在D盘的discuzz!打开后出现上述错误,请问应如何处理?winmysqladmin已经启动,但三色树上有一个小红点如果出现"ERROR 2003: Can't connect to MySQL server on 'localhost' (10061)",说明你的MySQL还没有启动.解决办法
