mysql安装常见的方法有四种

MySQL RPM包下载

官网下载地址：

https://dev.mysql.com/downloads/mysql/

1. yum安装依赖包

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

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.

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

✓ 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 --f

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

total 1168588
