介质下载地址：MySQL :: Download MySQL Community Server (Archived Versions)
本文中使用的为适用于Redhat 7的5.7.25的版本（5.7.25-el7-x86_64），其它版本类似。
本文介绍两种安装方法：rpm安装和tar安装，其它安装方案（例如yum、apt等），请参考官网。
不同版本的不同操作系统，可用的安装包和安装方式不尽相同，请根据实际情况进行安装。（例如，5.7.25的mysql，centos7的有rpm包和tar包，而centos6只有rpm包，只能使用rpm的方式安装）
rpm安装使用介质名称：mysql-5.7.25-1.el7.x86_64.rpm-bundle.tar
tar安装使用介质名称：mysql-5.7.25-el7-x86_64.tar.gz
使用rpm安装，需要卸载旧版本的mysql和相关组件（mariadb也要卸载）。
使用命令rpm -qa | grep mysql获取机器上已有的mysql相关组件，使用命令rpm -e --nodeps mysql***进行卸载，其中，--nodeps 参数会忽略其依赖关系
将tar包上传到服务器上，进行解包（tar -xvf *.tar）。解压出来四个文件：
mysql-community-common-5.7.25-1.el7.x86_64.rpm
mysql-community-libs-5.7.25-1.el7.x86_64.rpm
mysql-community-client-5.7.25-1.el7.x86_64.rpm
mysql-community-server-5.7.25-1.el7.x86_64.rpm使用rpm命令进行安装：
rpm -ivh mysql-community-common-5.7.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.25-1.el7.x86_64.rpm也可以先使用rpm安装server，rpm会警告缺少的组件，然后根据缺少的组件再一个个安装。
rpm安装的配置文件为/etc/my.cnf。
通过service或者systemctl进行操作：
service mysqld start
service mysqld stop
service mysqld restart
service mysqld statustar包的方式安装较为简单：将tar包上传到服务器上，使用tar进行解压（tar -zxvf ***.tar.gz），即可使用。
建议设置mysql的环境变量
export MYSQL_HOME=/app/mysql/mysql
export PATH=$PATH:$MYSQL_HOME/binmysqld --defaults-file=/app/mysql/log/mysql_3306.cnf &
mysqladmin -uuser_have_shutdown_power -p -S /tmp/mysql.sock shutdown配置文件可自由指定，但是在配置文件中，必须指出mysql组件的目录（basedir）
使用tar安装，首次启动前，需要初始化数据库，生成mysql相关的管理库（information_schema、mysql等）
mysqld --defaults-file=/app/mysql/log/mysql_3306.cnf --initialize
mysqld --defaults-file=/app/mysql/log/mysql_3306.cnf &初始化后，会在日志文件中生成默认密码，用默认密码登录后，必须修改密码
set password for root@localhost=password("password");较简单的配置文件如下：
[mysqld]
port = 3306
socket = /tmp/mysql.sock
basedir = /app/mysql/mysql
datadir = /app/mysql/data
log_error = /app/mysql/log/error.log
pid-file = /app/mysql/log/mysql_3306.pid
bind_address = 0.0.0.0
[client]
port = 3306
socket = /tmp/mysql.sock上面的配置文件，建议只用于个人测试，对稳定性、性能等要求较高的，可以参考下面的内容，同时，注意要根据实际情况修改

socket = /tmp/mysql.sock
