#安装插件
yum install -y wget 
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-server-5.7.39-1.el7.x86_64.rpm
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.39-1.el7.x86_64.rpm-bundle.tar

安装依赖
yum install -y libaio perl net-tools numactl autoconf perl-JSON initscripts

解压
cd /opt
mkdir /opt/mysql
tar -xvf /opt/mysql-5.7.39-1.el7.x86_64.rpm-bundle.tar -C /opt/mysql

安装
rpm -ivh /opt/mysql/*.rpm


初始化mysql
mysqld --initialize --user=root
后台启动
nohup mysqld --user=root &

通过查看mysqld日志，可以查看到默认的root用户临时密码
grep password /var/log/mysqld.log
密码：d4h9g<Th2NLQ
注意，如果默认密码存在诸如)之类的特殊符号，需要使用\进行转义
#登录
mysql -uroot -pd4h9g\<Th2NLQ
修改root用户临时密码：
ALTER USER 'root'@'localhost' IDENTIFIED BY '新的密码';
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
flush privileges;

编译安装
