关于mysql8的安装

wc7086

内存不足2GB的，是先判断是否满足mysql8安装条件才加swap，为什么不先加swap再判断呢？

centos7.6安装mysql8.0.15的时候也出现了和之前那个帖子一样的问题，错误提示都差不多，不过是在56%的时候出现，我安装mysql8.0.16的话则是一开始就出现...

https://bbs.vpser.net/thread-18524-1-1.html centos7.6出现与这个帖子相似的提示可以确定是gcc版本问题对吧,下面是8.0.16的错误提示

mysql 8.0.16需要gcc 5.3以上版本，centos 7的是4.8.5不符合要求，可以按 https://www.vpser.net/manage/centos-6-upgrade-gcc.html 升级gcc
同时升级cmake至3.4.3以上版本，升级方法：安装epel，然后

1. yum install cmake3
   
2. mv /usr/bin/cmake /usr/bin/cmake.old
   
3. ln -s /usr/bin/cmake3 /usr/bin/cmake

复制代码

后再试试
