安装mysql：

依次执行下面的命令

1、

rpm -ivh mysql-community-common-5.7.23-1.el7.x86_64.rpm

2、

rpm -ivh mysql-community-libs-5.7.23-1.el7.x86_64.rpm

3、

rpm -ivh mysql-community-client-5.7.23-1.el7.x86_64.rpm

4、

rpm -ivh mysql-community-server-5.7.23-1.el7.x86_64.rpm

注意，如果在执行server rpm包时报错

error: Failed dependencies: libnuma.so.1()(64bit) is needed by mysql-community-server-5.7.23-1.el7.x86_64 libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-server-5.7.23-1.el7.x86_64 libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-server-5.7.23-1.el7.x86_64

执行下面的命令然后重新执行server rpm包即可

sudo yum install numactl-libs

5、

rpm -ivh mysql-community-devel-5.7.23-1.el7.x86_64.rpm

启动mysql

systemctl start mysqld

修改密码及策略

查看初始密码

grep 'temporary password' /var/log/mysqld.log

如图中密码为 -l9qwXz.?elx

修改密码

mysql -uroot -p
#策略要求
set global validate_password_policy=0;
#密码长度
set global validate_password_length=4;
set password=password('123456');
grant all on *.* to root@'%' identified by '123456' with grant option;
flush privileges;

设置开机启动

systemctl enable mysqld
systemctl daemon-reload
