删除里面所有内容并把以下内容添加到里面

[mysql]

  :wq      //保存退出

chown mysql:mysql /etc/my.cnf       //配置文件属主与属组

#设置环境变量
echo 'PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile          
//把这两个路径添加到环境变量中，并放到profile文件中使之开机自运行，否则不生效
echo 'export PATH' >> /etc/profile                   //设为全局变量，使它使用环境更广

source /etc/profile               //立即生效

#初始化数据库
cd
cd /usr/local/mysql/

bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data

cp usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/

systemctl daemon-reload       
systemctl start mysqld
netstat -anpt | grep 3306    //查看服务运行状态

systemctl enable mysqld     //设为开机启动

#访问数据库操作
mysqladmin -u root -p password "abc123"    //给root账号设置密码
mysql -uroot  -pabc123      //登录数据库   
有密码的加“-p”,如果没有密码不用加“-p”
数据库安装配置成功，退出则输入”quit“
