Centos7安装MySQL8.0.33最新版本详细介绍

                                                 ! ! ! 跟着文档走安装不上我去吃shi

环境前准备：

● 操作系统：Centos7 X86架构

● Mysql安装版本：8.0.33

● 连接工具：Xshell/Xftp

 进入官网下载对应的版本

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

直接复制此链接即可

查看操作系统是ARM还是X86，下载对应架构。

[root@k8s-master02 log]# uname -m
x86_64

查看本地有没有安装mariadb ，有的话删除

[root@localhost ~]# rpm -qa |grep mariadb

[root@localhost ~]# rpm -e --nodeps 软件名

查看本地有没有安装mysql

[root@localhost ~]# rpm -qa |grep mysql

[root@localhost ~]#  rpm -e --nodeps 软件名

查找本地有没有Mysql文件

[root@localhost ~]# find / -name mysql

[root@localhost ~]# whereis mysql

[root@localhost ~]# rm -rf  #删除

 确保环境准备无误

[root@localhost ~]# rpm -qa |grep mariadb
[root@localhost ~]# find / -name mysql

[root@localhost ~]# rpm -qa |grep mysql

环境准备没问题开始上传Mysql安装包安装（rz/xftp）

[root@localhost ~]# ls
mysql-8.0.33-1.el7.x86_64.rpm-bundle.tar

 创建一个mysql目录存放解压出来的安装包

[root@localhost ~]# mkdir mysql

[root@localhost ~]# tar -xf mysql-8.0.33-1.el7.x86_64.rpm-bundle.tar -C mysql

[root@localhost ~]# cd mysql

[root@localhost mysql]# ls
mysql-commUnity-client-8.0.33-1.el7.x86_64.rpm
mysql-community-client-plugins-8.0.33-1.el7.x86_64.rpm
mysql-community-common-8.0.33-1.el7.x86_64.rpm

mysql-community-icu-data-files-8.0.33-1.el7.x86_64.rpm
mysql-community-libs-8.0.33-1.el7.x86_64.rpm
mysql-community-libs-compat-8.0.33-1.el7.x86_64.rpm

mysql-community-server-debug-8.0.33-1.el7.x86_64.rpm
mysql-community-test-8.0.33-1.el7.x86_64.rpm

 开始安装依赖按照顺序安装否则报错

rpm -ivh mysql-community-common-8.0.33-1.el7.x86_64.rpm 
rpm -ivh mysql-community-client-plugins-8.0.33-1.el7.x86_64.rpm 
rpm -ivh mysql-community-embedded-compat-8.0.33-1.el7.x86_64.rpm 
rpm -ivh mysql-community-libs-8.0.33-1.el7.x86_64.rpm 
rpm -ivh mysql-community-libs-compat-8.0.33-1.el7.x86_64.rpm 
yum install openssl-devel

rpm -ivh mysql-community-devel-8.0.33-1.el7.x86_64.rpm 

rpm -ivh mysql-community-client-8.0.33-1.el7.x86_64.rpm

yum -y install mysql-community*
rpm -ivh mysql-community-server-8.0.33-1.el7.x86_64.rpm 
rpm -ivh mysql-community-test-8.0.33-1.el7.x86_64.rpm 

 开始进行下一步

 mysqld --initialize --console                                         #初始化数据库

 chown -R mysql:mysql /var/lib/mysql/                         #给mysql目录属主属组改成mysql
 systemctl start mysqld                                                 #启动mysql
 systemctl status mysqld                                               #查看mysql状态（active running)

 cat /var/log/mysqld.log |grep passWord                        #查看mysql密码

 输入mysql密码

[root@localhost ~]# mysql -u root -p
Enter password: 

进入数据库以后要修改密码

mysql> alter user 'root'@'localhost' identified with mysql_native_password by '123123';
Query OK, 0 rows affected (0.00 sec)

 至此安装完成

设置远程连接

select host,user from user;

说明用户只能本地登录 

mysql> update user set user.host='%'where user.user='root';
Query OK, 1 row affected (0.01 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

 

 然后用我们的远程工具测试即可
