CentOS 7安装mysql(rpm)

1.检查是否安装了mysql

 

rpm -qa|grep -i mysql

 

centos7默认是安装的mariadb,而安装mysql的话会和mariadb的文件冲突,所以需要先卸载掉mariadb

2.卸载默认安装的mysql

 

rpm -e --nodeps mysql-libs-XX
yum remove mysql mysql-server mysql-libs mysql-server;

rpm -e --nodeps pcp-pmda-mysql-3.10.6-2.el7.x86_64

 

3.安装mysql,上传安装包

 

这里面有六个rpm包,下这一个就够了

tar  -xvf  MySQL-server-5.6.43-1.el7.x86_64.rpm-bundle.tar

六个只需要安装server和client就可以了

4.安装server

rpm -ivh MySQL-server-5.6.43-1.el7.x86_64.rpm 

如果这一步报错,缺少依赖可以不用管,使用下面的命令】

rpm -ivh MySQL-server-5.6.43-1.el7.x86_64.rpm --force --nodeps

5.安装client

rpm -ivh MySQL-client-5.6.43-1.el7.x86_64.rpm 

同样安装报错,缺少依赖

rpm -ivh MySQL-client-5.6.43-1.el7.x86_64.rpm --force --nodeps

6.启动mysql

service mysql start

7.设置密码

初始密码在 /root/.mysql_secret 这个文件里

 

cat /root/.mysql_secret

 

登陆

mysql -uroot -p初始密码

修改密码(root 是新密码)

set PASSWORD=PASSWORD('root');

8.赋权限

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION; 

GRANT ALL PRIVILEGES ON *.* TO 'root'@'hadoop02' IDENTIFIED BY 'root' WITH GRANT OPTION;

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

FLUSH PRIVILEGES;

查看user表的登陆权限

 

select host, user from user;

 

%可以任意ip登陆,不然除了本机连接会报错
