CentOS 7安裝mysql(rpm)

1.檢查是否安裝了mysql

 

rpm -qa|grep -i mysql

 

centos7默認是安裝的mariadb，而安裝mysql的話會和mariadb的文件沖突，所以需要先卸載掉mariadb

2.卸載默認安裝的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.安裝mysql，上傳安裝包

 

這里面有六個rpm包，下這一個就夠了

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

六個只需要安裝server和client就可以了

4.安裝server

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

如果這一步報錯，缺少依賴可以不用管，使用下面的命令】

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

5.安裝client

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

同樣安裝報錯，缺少依賴

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

6.啟動mysql

service mysql start

7.設置密碼

初始密碼在 /root/.mysql_secret 這個文件里

 

cat /root/.mysql_secret

 

登陸

mysql -uroot -p初始密碼

修改密碼（root 是新密碼）

set PASSWORD=PASSWORD('root');

8.賦權限

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表的登陸權限

 

select host, user from user;

 

%可以任意ip登陸，不然除了本機連接會報錯
