Centos7 如何部署MySQL8.0.30数据库

xz -d mysql-8.0.30-linux-glibc2.12-x86_64.tar.xz
# 将tar文件解压到/usr/local/目录下
tar -xvf mysql-8.0.30-linux-glibc2.12-x86_64.tar -C /usr/local
cd /usr/local/
# 修改MySQL文件名
mv mysql-8.0.30-linux-glibc2.12-x86_64 mysql-8.0.30
# 创建数据存放目录
mkdir /usr/local/mysql-8.0.30/data

yum search libaio

yum install libaio

vim /etc/profile

export MYSQL_HOME=/usr/local/mysql-8.0.30/bin
export PATH=$PATH:$MYSQL_HOME

source /etc/profile
