1.mysql-5.7.25-1.el6.x86_64.rpm-bundle.tar下载百度云资源

2.把下载的mysql安装包上传到Centos上
解压mysql，我这是在Windows上解压的上传到Centos上，我在Centos上解压mysql不知道为什么少了rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm包
tar –vxf mysql-5.7.25-1.el6.x86_64.rpm-bundle.tar
3.查看mysql依赖
rpm -qa | grep mysql
4.如果查看有mysql依赖，就删除mysql依赖,
rpm -e --nodeps `rpm -qa | grep mysql`
5.再次查是否有mysql依赖
rpm -qa | grep mysql
6.安装一定要按照顺序来
第一个安装： rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm报了一个错误
[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm
warning: mysql-community-common-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

原因：已存在MariaDB-common-10.4.8-1.el7.centos.x86_64的库（这是我以前安装MariaDB数据库，如果是别的也要根据对应的名字删除），所以需要先删除以前的库才能安装！
执行强制卸载命令：
rpm -e MariaDB-common-10.4.8-1.el7.centos.x86_64--nodeps
然后查看：
rpm –qa | grep mysql
再继续安装
rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm
[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm warning: mysql-community-common-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ########################################### [100%] 1:mysql-community-common ########################################### [100%]
第二个安装：
rpm -ivh mysql-community-libs-5.7.25-1.el6.x86_64.rpm
[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-libs-5.7.25-1.el6.x86_64.rpm warning: mysql-community-libs-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ########################################### [100%] 1:mysql-community-libs ########################################### [100%]
第三个安装
rpm -ivh mysql-community-client-5.7.25-1.el6.x86_64.rpm
[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-client-5.7.25-1.el6.x86_64.rpm warning: mysql-community-client-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ########################################### [100%] 1:mysql-community-client ########################################### [100%]
第四个安装
rpm -ivh mysql-community-server-5.7.25-1.el6.x86_64.rpm
[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-server-5.7.25-1.el6.x86_64.rpm warning: mysql-community-server-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ########################################### [100%] 1:mysql-community-server ########################################### [100%] You have new mail in /var/spool/mail/root
第五个安装
rpm -ivh mysql-community-devel-5.7.25-1.el6.x86_64.rpm
[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-devel-5.7.25-1.el6.x86_64.rpm warning: mysql-community-devel-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ########################################### [100%] 1:mysql-community-devel ########################################### [100%]
7.使用命令启动mysql服务
service mysqld start
[root@localhost mysql-5.7.25]# service mysqld start Starting mysqld: [ OK ] [root@localhost mysql-5.7.25]#
8.使用命令生成一个随机密码：grep "temporary password" /var/log/mysqld.log
[root@localhost mysql-5.7.25]# grep "temporary password" /var/log/mysqld.log 2020-04-07T12:32:39.276158Z 1 [Note] A temporary password is generated for root@localhost: >v>uyo:fg7.O [root@localhost mysql-5.7.25]#
注意：密码是root@localhost:右边的字符串
root@localhost: >v>uyo:fg7.O 这里生成的随机密码是：>v>uyo:fg7.O
MySQL 会在 /var/log/mysqld.log 日志中生成一个随机密码，默认需要修改密码才能使用
可以通过 vim /var/log/mysqld.log 打开里面有一行这样的代码
2020-04-07T12:32:39.276158Z 1 [Note] A temporary password is generated for root@localhost: >v>uyo:fg7.O
9.修改密码，先登录mysql
mysql -u root –p
[root@localhost mysql-5.7.25]# mysql -u root -p Enter password:
我这随机密码就是：>v>uyo:fg7.O
10.登录成功
[root@localhost log]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or g. Your MySQL connection id is 12 Server version: 5.7.25 Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.

Type 'c' to clear the current input statement. mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'wangqing'; Query OK, 0 rows affected (0.01 sec) mysql>
11.修改密码：
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';
12.设置权限
为了可以远程连接该数据库，需要设置相应的权限
#任何主机 mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '刚刚修改的密码' WITH GRANT OPTION; #指定主机 mysql>GRANT ALL PRIVILEGES ON *.* TO 'xxxx'@’xx.xx.xx.xx’ IDENTIFIED BY 'xxxx' WITH GRANT OPTION;
13.刷新权限
mysql>flush privileges;
这就完成了，可以用sql工具连接mysql了
