linux按照mysql为何如此简单_Linux系统为什么可以蠢到安装一个软件也那么困难？…

安装MySQL5.6和567区别为什么那么大辑根本不同。为什么部分用Linux的人有优越感呢/p>

啥叫5.6和567咩暂时认为你说的5.6和5.7吧。

那我来装一次小白(设定上我会用Linux简单的命令，但安装mysql零经验)，试试安装一下。

既然是mysql，那就找官 喽。官 不会找。。。。。我们没啥可说的了Download MySQL Yum Repository?dev.mysql.com

那我们就用暂时最常用的Centos7了。

下载repoRed Hat Enterprise Linux 7 / Oracle Linux 7 (Architecture Independent), RPM Package

下载下来是个rpm文件，那就拿rpm命令怼上rpm -i mysql80-community-release-el7-3.noarch.rpm

然后yum search mysql一下，发现mysql到位了，只不过是mysql8

我们要是5.6和5.7。那就搜一下其他版本

yum –showduplicates search mysql-community-server

…

========================================== N/S matched: mysql-community-server ==========================================

mysql-community-server-8.0.11-1.el7.x86_64 : A very fast and reliable SQL database server

mysql-community-server-8.0.12-1.el7.x86_64 : A very fast and reliable SQL database server

mysql-community-server-8.0.16-1.el7.x86_64 : A very fast and reliable SQL database server

mysql-community-server-8.0.16-2.el7.x86_64 : A very fast and reliable SQL database server

mysql-community-server-8.0.17-1.el7.x86_64 : A very fast and reliable SQL database server

mysql-community-server-8.0.18-1.el7.x86_64 : A very fast and reliable SQL database server

结果出来的都是8，略坑啊。

但刚才在mysql 站上下载repo的时候并没提示我们版本，估计是打包放一个repo文件里了。翻翻/etc/yum.repos.d/

cat /etc/yum.repos.d/mysql-community.repo

…

…

果然都在这呢，那就好办了。

yum –showduplicates –enablerepo mysql56-community –disablerepo mysql80-community search mysql-community-server

装呗

yum –enablerepo mysql56-community –disablerepo mysql80-community install mysql-community-server-5.6.46-2.el7.x86_64

启动一下

[root@mysql-test ~]# service mysqld start

Redirecting to /bin/systemctl start mysqld.service

[root@mysql-test ~]# mysql

这不就装好了么谁来给我解释一下难在哪里/p>

我琢磨这题主的智商没这么低吧道5.7有坑再试试5.7

卸载5.6，安装5.7

yum –enablerepo mysql56-community –disablerepo mysql80-community remove mysql-community-server-5.6.46-2.el7.x86_64

yum –showduplicates –enablerepo mysql57-community –disablerepo mysql80-community search mysql-community-server

yum –enablerepo mysql57-community –disablerepo mysql80-community install mysql-community-server-5.7.28-1.el7.x86_64

装好，启动

[root@mysql-test ~]# service mysqld start

Redirecting to /bin/systemctl start mysqld.service

[root@mysql-test ~]# mysql

这不又装好了么/p>

太不给面子了！！坑呢/p>

我倒是想装一次小白，可根本没机会啊，yum install全搞定了。把写帖子的时间都算进去，也就30分钟不到，这很困难么过来，我猜你在windows下折腾一个mysql可就没这么顺利了。

其实我们真不是有优越感，而是很多事情让我们很迷，这有什么可难的/p>

我找了个Windows下装MySQL的教程来，给你们体会一下win10系统，mysql-installer-community-5.7.19.0.msi安装 – 叮咚丶哈哈 – 博客园?www.cnblogs.com

VS

rpm -i mysql80-community-release-el7-3.noarch.rpm

yum –enablerepo mysql57-community –disablerepo mysql80-community install mysql-community-server-5.7.28-1.el7.x86_64

service mysqld start

mysql

前者30多步，后者一个复制粘贴就搞定了，你们为什么会觉得后者更困难/p> 文章知识点与官方知识档案匹配，可进一步学习相关知识CS入门技能树Linux入门在线安装软件24758 人正在系统学习中 相关资源：糖烟茶酒行业管理软件 烟酒进销存店铺销售收银管理系统
