CentOS 7.9 RPM安装Mysql数据库过程
1.查看系统版本
cat /etc/redhat-release
2.下载mysql 的安装文件
下载地址 https://downloads.mysql.com/archives/community/
3.检查服务器上是否安装mysql
rpm -qa | grep mysql 查看
rpm -e --nodeps 文件名字 卸载
卸载旧版本mariadb
rpm -qa|grep mariadb #查找mariadb
rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64 #卸载
4. 安装mysql所需要的依赖 ,如果不安装后面执行rpm可能会报错
yum -y install libaio yum -y install net-tools yum -y install perl
5.rpm 执行顺序(严格按照这个顺序执行)
rpm -ivh mysql-community-common-5.7.36-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.36-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.36-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.36-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.36-1.el7.x86_64.rpm
记得修改my.cnf
6. 启动MySQL
service mysqld start
7.查看临时密码
grep password /var/log/mysqld.log
8.修改密码
用查看的临时密码去登录数据库 mysql -uroot –p 修改密码 set password for root@localhost=password(‘aniu@123’);
9.配置数据库远程链接
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION;
mysql>FLUSH PRIVILEGES;
mysql>exit;
大功告成!!!
