********************mysql-5.7.17安装
tar -zxvf mysql-5.7.17.tar.gz
mv mysql-5.7.17-linux-glibc2.5-x86_64 mysql
检查mysql组和用户是否存在，如无创建
groupadd mysql // 建一个msyql的用户和组
useradd -g mysql mysql
mkdir /usr/local/mysql // 创建目录
mkdir /usr/local/mysql/data // 数据仓库目录
chown -R mysql ./mysql
chgrp -R mysql ./mysql
初始化
./bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize --console
报错： error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
yum install -y libaio
./bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize --console
密码：

R#R&UFuNg5sd
cp ./support-files/my-default.cnf /etc/my.cnf
cp ./support-files/mysql.server /etc/init.d/mysql
修改密码：
mysql -uroot -p
set password=password('BuShu*JTJY2020!');
grant all privileges on *.* to 'root'@'%' identified by 'BuShu*JTJY2020!';
flush privileges;
如果是忘记密码：
vim /etc/my.cnf
在 [mysqld] 的段中加上一句：skip-grant-tables
重启 mysql 服务， service mysql restart
在输入 mysql -u root -p 输入回车即可进入 mysql 数据库
use mysql;
低版本修改：update user set Password = password('BuShu*JTJY2020!') where user = 'root';
高版本修改：update user set authentication_string=password('BuShu*JTJY2020!') where user = 'root';
flush privileges;
配置环境变量
export PATH=/usr/local/mysql/bin:$PATH
然后立马生效，执行
source /etc/profile
Failed to start mysqld.service: Unit not found
首先需要安装mariadb-server
yum install -y mariadb-server
启动服务
/bin/systemctl start mariadb.service
添加到开机启动
/bin/systemctl enable mariadb.service
/bin/systemctl start mysqld.service
