一、MySQL官网获取下载地址

当我们需要安装MySQL的某一个版本的时候，访问MySQL的官网：https://www.mysql.com/->DOWNLOADS->Archives->MySQL Community Server，选择版本，操作系统，操作系统版本，下载RPM Bundle。这个时候获取到 下载 地址：https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar

二、下载和解压

wget -c https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar

tar vxf mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar

解压后的文件RPM文件列表：

mysql-community-libs-5.7.20-1.el7.x86_64.rpm
mysql-community-client-5.7.20-1.el7.x86_64.rpm
mysql-community-libs-compat-5.7.20-1.el7.x86_64.rpm
mysql-community-common-5.7.20-1.el7.x86_64.rpm
mysql-community-minimal-debuginfo-5.7.20-1.el7.x86_64.rpm
mysql-community-devel-5.7.20-1.el7.x86_64.rpm
mysql-community-server-5.7.20-1.el7.x86_64.rpm
mysql-community-embedded-5.7.20-1.el7.x86_64.rpm
mysql-community-server-minimal-5.7.20-1.el7.x86_64.rpm
mysql-community-embedded-compat-5.7.20-1.el7.x86_64.rpm
mysql-community-test-5.7.20-1.el7.x86_64.rpm

mysql-community-embedded-devel-5.7.20-1.el7.x86_64.rpm

三、安装

yum localinstall mysql-community-common-5.7.20-1.el7.x86_64.rpm

yum localinstall mysql-community-libs-5.7.20-1.el7.x86_64.rpm

yum localinstall mysql-community-client-5.7.20-1.el7.x86_64.rpm

yum localinstall mysql-community-server-5.7.20-1.el7.x86_64.rpm

当安装common的时候，遇到冲突的时候用yum remove mariadb-libs-1:5.5.56-2.el7.x86_64或者rpm -e mariadb-libs-1:5.5.56-2.el7.x86_64卸载冲突包。

三、修改root本地密码

 

mysql安装完成之后，在/var/log/mysqld.log文件中给root生成了一个默认密码。通过下面的方式找到root默认密码，然后登录mysql进行修改：

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

进入MySQL：

mysql -u root -p

查看密码策略

show variables like '%password%'

设置密码策略：

set global validate_password_policy=0;

查看密码策略：

select @@validate_password_policy;

设置密码长度：

set global validate_password_length=4;

查看密码长度：

select @@validate_password_length;

然后你就可以将你的密码改为简单的密码。

alter user 'root'@'localhost' identified by '123456';

或者

set password for 'root'@'localhost'='123456';

此set password for 'root'@'localhost'=password('123456');命令将被弃用。

允许远程访问

grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;

grant all on *.* to 'root'@'%';

其中123456为你的访问密码。

mariadb 其实就是 mysql，只不过是 mysql 的另一种拉出来的开源分支，也可以正常使用，如果不想卸载也是可以的。安装 MySQL 源：rpm -Uvh mysql57-community-release-el7-10.noarch.rpm。安装 MySQL 服务端，需要等待一些时间：yum install -y mysql-community-server。通过临时密码登录 MySQL，进行修改密码操作：mysql -uroot -p。这时候我们就可以自己设置想要的密码了。

前言目录按需挂载，空闲时自动卸载，可以采用automount技术。尤其是在大型HPC环境，成千上万的用户家目录，使用automount降低seek time，提高dentry缓存命中率，可大大节省内存资源。环境RHEL 8实践安装nfs-utils，它提供nfs server， 创建目录并导出，启动nfs server， 在客户端，安装autofs， 参考/misc配置项，对家目录进行配置，并启动autofs服务， 检查/home/nfs目录，没有任何文件（夹）， 触发一下其中一个子目录
