1、卸载mariadb

由于银河麒麟v10系统默认安装了mariadb 会与Mysql相冲突，因此首先需要卸载系统自带的mariadb
查看系统上默认安装的Mariadb软件包
使用yum查看已经安装的mariadb软件包

yum list --installed mariadb

rpm -qa|grep mariadb

查看默认的mariadb配置文件

在这里插入代码片

默认的配置文件是 /etc/my.cnf

查看默认的mariadb配置目录

find / -type d  -name my.cnf*

使用yum卸载 mariadb

yum remove mariadb.x86_64

验证卸载Mariadb成功

查看Mariadb配置文件和目录是否还存在 已经不存在了

至此mariadb卸载完成

2、下载Mysql安装包

访问官网下载链接 链接: https://dev.mysql.com/downloads/mysql/

选择如下 点击下载按钮 下载安装包

3、安装Mysql 8.35

官方安装文档 链接: https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/binary-installation.html

3.1、安装依赖包

yum search libaio

yum install libaio

3.2、安装Mysql

命令顺序如下 安装包放在/root/package/mysql/mysql-8.0.35-linux-glibc2.28-x86_64.tar.xz

groupadd mysql
useradd -r -g mysql -s /bin/false mysql
cd /usr/local
tar -xJvf /root/package/mysql/mysql-8.0.35-linux-glibc2.28-x86_64.tar.xz
ln -s /usr/local/mysql-8.0.35-linux-glibc2.28-x86_64/ mysql
cd mysql
mkdir mysql-files
chown mysql:mysql mysql-files
chmod 750 mysql-filesecho -e "[mysqld]\ndatadir=/var/lib/mysql/data\nbasedir=/var/lib/mysql\nsocket=/var/lib/mysql/mysql.sock\nuser=mysql\nport=3306\ncharacter-set-server=UTF8MB4\nsymbolic-links=0\nsql-mode=STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION\n[mysqld_safe]\nlog-error=/var/log/mysqld/mysqld.log\npid-file=/var/run/mysqld/mysqld.pid\n[client]\nport=3306\nsocket=/var/lib/mysql/mysql.sock"  >> /etc/my.cnfchown mysql:mysql /etc/my.cnfmkdir -p /var/lib/mysql/data
chown mysql:mysql /var/lib/mysqlmkdir -p /var/log/mysqld/
touch /var/log/mysqld/mysqld.log
chown -R mysql:mysql /var/log/mysqld
chmod 777 /var/log/mysqld/mysqld.logmkdir -p /var/run/mysqld/
chown mysql:mysql /var/run/mysqld/
chmod 777 /var/run/mysqld/mkdir -p /var/lib/mysql/bin
cp bin/mysqld_safe /var/lib/mysql/bin
chown -R mysql:mysql /var/lib/mysqlbin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysqlbin/mysql_ssl_rsa_setup
bin/mysqld_safe --user=mysql &
# Next command is optional
cp support-files/mysql.server /etc/init.d/mysql.server

其中执行bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql 会打印出Mysql的默认密码
最后一句：A temporary password is generated for root@localhost: Wyfu?iFAW8tY

[root@kylin mysql]# bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql

vi /etc/profile 最后面添加2行

export MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin

使用安装Mysql数据库 时生成的默认密码登录mysql数据库

mysql -uroot -p

没修改默认密码前不能进行数据库sql操作

修改Mysql默认密码为Mysql@123
