一、下载解压

下载地址： MySQL :: Download MySQL Community Server (Archived Versions)

tar -xvf mysql-8.0.32-1.el7.x86_64.rpm-bundle.tar -C /opt/mysql-8.0.32

 二、安装

最开始安装一直报错

参考博客：https://blog.51cto.com/flyfish225/10596050

 缺少 libcrypto.so.10库文件,安装openssl可以解决

wget http://mirror.centos.org/centos/8-stream/AppStream/x86_64/os/Packages/compat-openssl10-1.0.2o-4.el8.x86_64.rpm

# 如果报404，用这个
wget http://mirrors.aliyun.com/centos/8-stream/AppStream/x86_64/os/Packages/compat-openssl10-1.0.2o-4.el8.x86_64.rpm

rpm -ivh compat-openssl10-1.0.2o-4.el8.x86_64.rpm --nodeps

2.还是按之前的安装方法

rpm -hiv mysql-community-common-8.0.32-1.el7.x86_64.rpm
rpm -hiv mysql-community-client-plugins-8.0.32-1.el7.x86_64.rpm
rpm -hiv mysql-community-libs-8.0.32-1.el7.x86_64.rpm
rpm -hiv mysql-community-client-8.0.32-1.el7.x86_64.rpm --force --nodeps  # 安装失败，添加 --force --nodeps
rpm -hiv mysql-community-icu-data-files-8.0.32-1.el7.x86_64.rpm
rpm -hiv mysql-community-server-8.0.32-1.el7.x86_64.rpm

备注：后续安装 报错执行过命令

yum install -y net-tools
yum update
yum install libcrypto*
 
yum install -y net-tools
yum install -y libaio
yum install -y perl

三、启动mysql

启动MySQL服务
systemctl start mysqld
 
查看MySQL的进程并设置服务器开机启动mysql
systemctl status mysqld
systemctl enable mysqld
 
查看初始化密码
cat /var/log/mysqld.log | grep password

mysql启动成功，但是查看版本提示异常

参考博客：mysql启动时报错：error while loading shared libraries: libncurses.so.5: cannot open shared object file的解决办法_Mysql_脚本之家

ln -s /usr/lib64/libncurses.so.6 /usr/lib64/libncurses.so.5
ln -s /usr/lib64/libtinfo.so.6 /usr/lib64/libtinfo.so.5

接下来进行下一步操作

查看初始化密码
cat /var/log/mysqld.log | grep password
 
mysql -uroot -p 初始密码
ALTER USER 'root'@'localhost' IDENTIFIED WITH MYSQL_NATIVE_PASSWORD BY '******';
 
use mysql;
update user set host = '%' where user ='root';
flush privileges;
 
ps: 用mysql连接工具就可以正常连接了。
