1.将mysql-5.7.37-1.el7.x86_64.rpm-bundle.tar包上传到mysql官网推荐位置 /usr/local/mysql

[root@sql1 local]# mkdir usr/local/mysql #创建mysql文件夹
1

2.解压mysql-5.7.37-1.el7.x86_64.rpm-bundle.tar包

[root@sql1 mysql]# tar -xf mysql-5.7.37-1.el7.x86_64.rpm-bundle.tar
1

3.因为是离线环境，建议在使用yum命令前先用以下命令清除本地mirrorlist

[root@sql1 mysql]# yum clean expire-cache
1

4.执行安装（{server,client,common,libs} 为必备，上文截图解压出的安装包并不需要全部安装）

[root@sql1 mysql]# yum localinstall -y install mysql-community-{server,client,common,libs}-*
1

如果失败，就需要手动一个一个安

rpm -ivh mysql-community-common-5.7.37-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.37-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.37-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.37-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.37-1.el7.x86_64.rpm

如果安装最后一个失败，缺少依赖

yum -y install libaio
yum -y install net-tools
yum -y install perl
1

3

依赖装后再运行 rpm -ivh mysql-community-server-5.7.37-1.el7.x86_64.rpm

5启动mysql

.[root@sql1 mysql]# systemctl start mysqld
.[root@sql1 mysql]# systemctl status mysqld
1
2

6.查看mysql临时密码并修改

[root@sql1 mysql]# grep 'temporary password' /var/log/mysqld.log
1

临时密码登录

[root@sql1 mysql]# mysql -uroot -p5esKph9c%s#P
1

修改登录密码 ps:如果想密码简单点就配置 mysql> set global validate_password_policy=LOW;
修改密码

ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';
1

7.修改访问权限，设置允许远程访问

mysql> use mysql;
mysql> select Host,User from user;
mysql> update user set Host='%' where User='root';
mysql> flush privileges;
 grant all privileges on *.* to 'root'@'%' with grant option;

8.#打开配置文件my.cnf

[root@localhost src]# vi /etc/my.cnf

#在[mysqld]下面配置几行

lower_case_table_names=1 #配置表名不区分大小写 1：不区分大小写 0：区分大小写 这行必须配置 默认表名是区分大小写的，不利于开发

character-set-server=utf8 #设置为默认编码为utf8

max_connections=1024 #设置最大连接数

[root@localhost src]# service mysqld restart #重启mysql 重启配置才能生效
1

配置参考
vim /etc/my.cnf
