前言
MySQL 是一个关系型数据库管理系统，由瑞典 MySQL AB 公司开发，目前属于 Oracle 公司。 MySQL是一种关联数据库管理系统，关联数据库将数据保存在不同的表中，而不是将所有数据放在一个大仓库内，这样就增加了速度并提高了灵活性。 本文详细介绍了MySQL在Window及Linux环境下安装的各种方法一、MySQL 安装简介
1.1 Linux 环境安装MySQL
在 Linux 下可以使用如下 3 种方式来安装：
a.RPM （Redhat Package Manage）：安装简单，适合初学者学习使用，
一台服务器只能安装一个 MySQL，Red Hat Enterprise Linux / Oracle Linux
b.二进制（ Binary Package）：安装简单；可以安装到任何路径下，灵活性好；
一台服务器可以安装多个 MySQL，Linux - Generic
c.源码（ Source Package）：在实际安装的操作系统进行可根据需，要定制编译，最灵活；性能最好；
一台服务器可以安装多个 MySQL，Source Code
1.2 Windows环境安装MySQL
在 Linux 下可以使用如下2 种方式来安装：
a.迷你版安装MySQL,图形化界面引导，安装简单，部署便捷，一台服务器可以部署多个MySQL
b.二进制安装，安装包解压后，命令直接部署，一台服务器可以部署多个MySQL
二、Linux 环境安装各个版本MySQL
注：以下安装均来自客户真实环境Linux服务器部署
详细过程可观看CSDN发布的视频教程：
MySQL数据库安装实战
2.1 Linux环境RPM包安装MySQL
OS环境：CentOS7.3
MySQL版本：8.0.27
2.1.1 MySQL RPM包下载
官网下载地址：
https://dev.mysql.com/downloads/mysql/
2.1.2 yum安装依赖包
本地yum源配置请参考CSDN博客：
Linux配置本地yum源，高效便捷:https://blog.csdn.net/weixin_41645135/article/details/120557997
yum -y install lrzsz wget perl-Digest-MD5
yum -y install numactl
yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make
2.1.3 添加用户及组
[root@jeames ~]# groupadd mysql
删除组:groupdel users
--用户加到组并指定根目录
[root@jeames ~]# useradd -g mysql -d /home/mysql mysql
useradd: warning: the home directory already exists.
Not copying any file from skel directory into it.
删除用户:userdel mysql
[root@jeames ~]# passwd mysql
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
2.1.4 安装Mysql
[root@jeames ~]# md5sum mysql-8.0.27-1.el8.x86_64.rpm-bundle.tar
edf4d0f95867f62cdcc97b7349bedc59 mysql-8.0.27-1.el8.x86_64.rpm-bundle.tar
[root@jeames ~]# tar -xvf mysql-8.0.27-1.el8.x86_64.rpm-bundle.tar -C /home/mysql/
## 必须安装的四个RPM包
mysql-community-common-8.0.27-1.el8.x86_64.rpm
mysql-community-libs-8.0.27-1.el8.x86_64.rpm
mysql-community-client-8.0.27-1.el8.x86_64.rpm 是客户端的安装包
mysql-community-server-8.0.27-1.el8.x86_64.rpm 是服务端的安装包
## 授权
root@jeames ~]# chown -R mysql:mysql /home/mysql/
## 安装
注：root用户下操作
[root@jeames ~]# cd /home/mysql/
装顺序：包之间相互依赖，所以必须注意安装顺序
✓ 先装 common
✓ 再装 libs
确保 mariadb 已卸载，centos7 默认支持 mariadb，不支持 mysql，不卸载会出现冲突
✓ 再装 client
✓ 最后装 server
[root@jeames mysql]# rpm -ivh mysql-community-common-8.0.27-1.el8.x86_64.rpm
[root@jeames mysql]# rpm -ivh --force --nodeps mysql-community-libs-8.0.27-1.el8.x86_64.rpm
[root@jeames mysql]# rpm -ivh mysql-community-client-8.0.27-1.el8.x86_64.rpm --force --nodeps
[root@jeames mysql]# rpm -ivh mysql-community-server-8.0.27-1.el8.x86_64.rpm --force --nodeps
2.1.5 初始化
详细的三个坑处理方法请参考以下CSDN博客：
https://blog.csdn.net/weixin_41645135/article/details/121479650
CentOS7.3部署Mysql8.0.27全过程，RPM包安装各种坑的处理```
初始化的时候会有三个坑
第一个抗：
[root@jeames mysql]# mysqld --initialize
mysqld: error while loading shared libraries: libssl.so.1.1: cannot open shared object file:
No such file or directory
第二个坑：
GLIBCXX版本太低报错
第三个坑：
mysqld: /lib64/libc.so.6: version `GLIBC_2.28' not found (required by mysqld)
mysqld: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /lib64/libstdc++.so.6)
注意：以上操作之后重启服务器后然后再初始化Mysql
[root@jeames mysql]# mysqld --initialize
2.1.6 启动MySQL
[root@jeames ~]# chown mysql:mysql /var/lib/mysql -R
[root@jeames ~]# systemctl start mysqld
[root@jeames ~]# systemctl status mysqld
[root@jeames ~]# systemctl enable mysqld
[root@jeames ~]# cat /var/log/mysqld.log | grep password
2.1.7 远程登陆
mysql> create user root@'%' identified with mysql_native_password by 'root';
mysql> grant all on *.* to root@'%' with grant option;
mysql> flush privileges;
2.2 Linux环境二进制安装MySQL
OS环境：RHEL7.6
MySQL版本：8.0.27
2.2.1 MySQL二进制包下载
官网下载地址：https://dev.mysql.com/downloads/mysql/
2.2.2 yum安装依赖包
本地yum源配置请参考CSDN博客：
https://blog.csdn.net/weixin_41645135/article/details/120557997
Linux配置本地yum源，高效便捷
[root@rhel76 ~]# yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make
2.2.3 卸载MariaDB
[root@rhel76 ~]# rpm -qa |grep mariadb
mariadb-libs-5.5.60-1.el7_5.x86_64
[root@rhel76 ~]# rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64
2.2.4 安装 MySQL
## 用户及目录创建
注：可以部署多个实例，通过端口区分root 用户操作：
mkdir -p /mysql/data/mysql3306
mkdir -p /mysql/app/
mkdir -p /mysql/conf/
mkdir -p /mysql/data/mysql3306/pid/
mkdir -p /mysql/data/mysql3306/socket/
mkdir -p /mysql/data/mysql3306/log/
mkdir -p /mysql/data/mysql3306/binlog/
mkdir -p /mysql/data/mysql3306/errlog
mkdir -p /mysql/data/mysql3306/relaylog/
mkdir -p /mysql/data/mysql3306/slowlog/
mkdir -p /mysql/data/mysql3306/tmp/
## 用户及组
[root@rhel76 ~]# groupadd mysql
[root@rhel76 ~]# useradd -g mysql mysql
[root@rhel76 ~]# chown -R mysql:mysql /mysql
[root@rhel76 ~]# passwd mysql
Changing password for user mysql.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@rhel76 ~]# cat /etc/group | grep mysql
mysql:x:1001:
[root@rhel76 ~]# cat /etc/passwd | grep mysql
mysql:x:1001:1001::/home/mysql:/bin/bash
## 上传软件包并解压
[root@rhel76 ~]# cp mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz /mysql/app
[root@rhel76 ~]# chown -R mysql:mysql /mysql
mysql用户操作
[root@rhel76 ~]# su - mysql
md5 值验证，保证下载到的软件包无破损无木马
[mysql@rhel76 ~]$ cd /mysql/app
[mysql@rhel76 app]$ ll
total 1168588
-rw-r--r-- 1 mysql mysql 1196633756 Nov 24 00:49 mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz
[mysql@rhel76 app]$ md5sum mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz
0bdd171cb8464ba32f65f7bf58bc9533 mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz
解压软件包并重命名
[mysql@rhel76 app]$ tar xvf mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz
[mysql@rhel76 app]$ mv mysql-8.0.27-linux-glibc2.12-x86_64 mysql8.0.27
[mysql@rhel76 app]$ ll

-rw-r--r-- 1 mysql mysql 1196633756 Nov 24 00:49 mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz
2.2.5 环境变量配置
cat >> /home/mysql/.bash_profile << "EOF"
MYSQL_HOME=/mysql/app/mysql8.0.27
PATH=$PATH:$HOME/.local/bin:$HOME/bin:$MYSQL_HOME/bin
EOF
source ~/.bash_profile
which mysql
2.2.6 创建参数文件
由于是二进制文件安装，数据库参数文件需要自己配置
cat >> /mysql/conf/my3306.cnf << "EOF"

2.2.7 数据库初始化
mysql用户操作：
mysqld --defaults-file=/mysql/conf/my3306.cnf --initialize --user=mysql --basedir=/mysql/app/mysql8.0.27 --datadir=/mysql/data/mysql3306/data/
注意：以上同一行执行
2.2.8 启动MySQL
[mysql@rhel76 ~]$ mysqld_safe --defaults-file=/mysql/conf/my3306.cnf --user=mysql &
[1] 21406
[mysql@rhel76 ~]$ 2021-11-24T06:14:23.240372Z mysqld_safe Logging to '/mysql/data/mysql3306/errlog/err3306.log'.

2.2.9 登陆MySQL
第一次登录 MySQL 时，需要到错误日志下找初始化密码，我这里的密码为：-(Qy5Aj9t,=a
使用 socket 加密码登录进去后，无法查询任何东西，提示先要修改 root 密码。
[mysql@rhel76 ~]$ cat /mysql/data/mysql3306/errlog/err3306.log | grep password

三、Windows环境安装各个版本MySQL
3.1 Windows环境MSI图形安装MySQL
OS环境：Windows7旗舰版，Service Pack1 64w位操作系统
MySQL版本：8.0.23
安装详细过程请参考以下CSDN博客：
https://blog.csdn.net/weixin_41645135/article/details/115500795
Windows安装Mysql-msi 图形安装
3.1.1 MySQL MSI包下载
官网下载地址：https://downloads.mysql.com/archives/community/
3.1.2 安装MySQL
3.1.3 客户端工具连接
安装包：Navicat Premium 12 绿色破解版.zip ，解压即可用
3.2 Windows环境二进制安装MySQL
OS环境：Server2012操作系统
MySQL版本：8.0.23
3.2.1 MySQL二进制包下载
官网下载链接：https://downloads.mysql.com/archives/installer/
3.2.2 初始化
G:\mysql-8.0.23-winx64\bin\mysqld --initialize --user=mysql --console --basedir=G:\mysql-8.0.23-winx64 \
--datadir=G:\mysql-8.0.23-winx64\data80323308
以上记住同一行执行
3.2.3 参数文件
[mysqld]
port=3306
basedir=C:\Program Files\MySQL
datadir=C:\Program Files\MySQL\Data
max_connections=200
max_connect_errors=10
character-set-server=utf8mb4
default-storage-engine=INNODB
default_authentication_plugin=mysql_native_password
3.2.4 安装
G:\mysql-8.0.23-winx64\bin\mysqld install mysql80323308 --defaults-file="G:\mysql-8.0.23-winx64\data80323308\mysql80323308.ini"
安装好之后，Mysql8.0需要重置密码才可以
##密码修改
alter user root@'localhost' identified with mysql_native_password by 'root';
flush privileges;
安装后密码忘记需要重置Mysql8.0密码，请参考博客
