yum安装mysql8.0
要使用yum安装MySQL 8.0,您需要按照以下步骤操作:
1. 首先,添加MySQL Yum存储库。您可以使用以下命令将MySQL的存储库添加到您的系统中:
yum -y install https://repo.mysql.com//mysql80-community-release-el7-3.noarch.rpm
2. 接下来,运行以下命令将服务器的包信息下载到本地电脑缓存起来:
yum makecache
3. 然后,使用yum安装MySQL Community Server:
sudo yum -y install mysql-community-server
这样就完成了MySQL 8.0的安装。请确保您已经备份了CentOS的yum源,并删除了已经安装的MySQL或mariadb版本。如果您还没有wget命令,可以通过运行以下命令来安装它:
yum -y install wget
然后,您可以使用wget命令下载MySQL的rpm包:
wget https://repo.mysql.com//mysql80-community-release-el7-7.noarch.rpm
接下来,使用以下命令安装刚刚下载的rpm包:
rpm -ivh mysql80-community-release-el7-7.noarch.rpm
完成安装后,您可以设置新密码并重新启动MySQL。使用以下命令登录数据库并修改密码:
mysql -u root -p
ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';
flush privileges;
然后,您可以重新登录并测试MySQL是否正常工作:
mysql -u root -p
这样,您就成功地使用yum安装了MySQL 8.0版本。请记住,在执行这些操作之前,确保您已经备份了相关的文件和数据。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
