1 用./upgrade.sh mysql 升级到mysql 8.0.16,报下面的错误。

Uncompress mysql-boost-8.0.16.tar.gz...
cd mysql-8.0.16...
^[[0;34m[+] Download or use exist boost...^[[0m

2 然后我 yum install cmake3 安装了cmake3。
3 我又重新用./upgrade.sh mysql 升级到mysql 8.0.16,然后报下面的错误:
============================check files==================================
mysql-boost-8.0.16.tar.gz [found]
============================check files==================================

If the database is large, the backup time will be longer.

[root@colin-aliyun lnmp1.6-full]# mysql
bash: mysql: command not found



这个情况应该怎么处理呢?

只安装上肯定是没有的他不会去主动找cmake3,只会找默认cmake
mv /usr/bin/cmake /usr/bin/cmake.old
ln -s /usr/bin/cmake3 /usr/bin/cmake
或直接
yum remove cmake 把老版本的卸载掉
再 ln -s /usr/bin/cmake3 /usr/bin/cmake

升级失败需要按教程恢复mysql后再进行升级
