1.MySQL安装
安装与卸载中,用户全部切换成为root,一旦 安装,普通用户能使用的
1.卸载不要的环境
shell
root@iZuf68hz06p6s2809gl3i1Z:~# ps ajx |grep mariadb
480217 480237 480236 480217 pts/0 480236 R+ 0 0:00 grep --color=auto mariadb
root@iZuf68hz06p6s2809gl3i1Z:~# systemctl stop mariadb.service
Failed to stop mariadb.service: Unit mariadb.service not loaded.
root@iZuf68hz06p6s2809gl3i1Z:~# ps axj |grep mariadb
480217 480243 480242 480217 pts/0 480242 R+ 0 0:00 grep --color=auto mariadb
这些命令表明我的系统上没有安装或运行MariaDB数据库服务,所以就不管了。
2.检查系统安装包
然后检测系统安装包
shell
root@iZuf68hz06p6s2809gl3i1Z:~# rpm -qa | grep mariadb
我这边发现没什么安装包,就不管了,如果有的话就要试着sudo yum remove mariadb,把这些安装包卸载
3.获取mysql官方yum源
然后查看自己的系统版本
shell
root@iZuf68hz06p6s2809gl3i1Z:~# cat /etc/os-release

root@iZuf68hz06p6s2809gl3i1Z:~#
可以进入 http://repo.mysql.com/, 找一下和自己版本一致的资源下载到你的本地,然后上传到你的Linux服务器
注意:最好安装和自己系统一致的mysql版本,否则可能会存在软件兼容性问题


实在搞不准可以去把这些文字复制下来问ai
4.安装mysql yum 源,对比前后yum源
创建存放MySQL的文件夹
shell
root@iZuf68hz06p6s2809gl3i1Z:~# cd 108_class
root@iZuf68hz06p6s2809gl3i1Z:~/108_class# ls
abc lesson3 newdir test.txt
root@iZuf68hz06p6s2809gl3i1Z:~/108_class# mkdir MySQL
root@iZuf68hz06p6s2809gl3i1Z:~/108_class# cd MySQL
然后安装:
shell
root@iZuf68hz06p6s2809gl3i1Z:~/108_class/MySQL# wget https://dev.mysql.com/get/mysql-apt-config_0.8.34-1_all.deb

安装下载的APT配置包:
bashsudo dpkg -i mysql-apt-config_0.8.34-1_all.deb.1(注意文件名末尾有".1",这是wget在目标文件已存在时自动添加的)
在安装过程中,会出现一个配置对话框,您可以选择要安装的MySQL版本。默认选项通常是可以的,选择"Ok"继续。
-
更新软件包列表:
bashsudo apt update -
安装MySQL服务器:
bashsudo apt install mysql-server在安装过程中,您将被要求为MySQL root用户设置密码。输入密码后回车。
-
安装完成后,检查MySQL服务的状态:
bashsystemctl status mysql -
登录到MySQL以验证安装:
bashmysql -u root -p然后输入您在安装时设置的密码。
shell
root@iZuf68hz06p6s2809gl3i1Z:~/108_class/MySQL# mysql -u root -p
Enter password:
