军哥你好：
安装好lnmp 1.3之后，运行两个网站，但是mysql会挂掉，也没有时间的规律，突然就挂掉了，每次重启lnmp restart，就恢复了。

err的日志：

内存可能不足了
你内存多大，建议把 innodb_buffer_pool_size 调小一些，再观察看看

主机的内存是2G，现在这里设置的是：256M.

调整到128或者64M ？

军哥您好，另外一个阿里云的ECS，是2核4G内存的；

innodb_buffer_pool_size 之前设置的大小是：512M，也会导致数据库挂掉，但是不是很频繁，一般是1~2天才挂一次，是不是也要调整小一点，比如设置成256M ？

谢谢。

另外，刚才查看了数据库编码，都是mysiam的，这样是不是可以关闭InnoDB这个数据库引擎？

谢谢。

回复 7# 的帖子


2G的话设置128MB把，4G的256MB

mysql 5.6的话，编辑/etc/my.cnf
innodb=OFF
ignore-builtin-innodb
skip-innodb
default_storage_engine = MyISAM
default_tmp_storage_engine = MyISAM

将#loose-innodb 那些行前面的# 删掉
