Posted 2020-09-01 SmarTom

1. ?官方下载地址:

   wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.17-1.el6.x86_64.rpm-bundle.tar

2. 解压:

   tar xvf mysql-5.7.17-1.el6.x86_64.rpm-bundle.tar

3. 卸载之前的版本

   rpm -qa | grep -i mysql

   rpm -e --nodeps 要卸载的mysql版本

4. 按照步骤来安装就好

   1.rpm -ivh mysql-community-libs-5.7.17-1.el6.x86_64.rpm --nosignature

   2.rpm -ivh mysql-community-devel-5.7.17-1.el6.x86_64.rpm  --nosignature

   3.rpm -ivh mysql-community-client-5.7.17-1.el6.x86_64.rpm  --nosignature

   4.rpm -ivh mysql-community-server-5.7.17-1.el6.x86_64.rpm  --nosignature

5. 修改密码 （有点特殊 ）

        1.找到my.cnf |  本机  /etc/my.cnf

        2.[mysqld]#下添加

          skip-grant-tables=1 #不用验证

        3.开启mysql /etc/init.d/mysqld start|本机默认地址

        4.进入并修改（依次命令）

    ?        1. mysql -uroot -p;

    ?        2.use mysql

    ?        3.update user set authentication_string = password(‘123456‘), password_expired = ‘N‘, password_last_changed = now() where user = ‘root‘;

    ?     ?5.my.cnf |  本机  /etc/my.cnf 里面删除skip-grant-tables=1 

    ?6.测试

    ?    mysql -uroot -p123456 -e "show databases;";

    ?7.OK收工;

遇到的错误总结:

1.默认提示需要输入校验码

[[email protected] tool]# rpm -ivh mysql-community-devel-5.7.17-1.el6.x86_64.rpm 

warning: mysql-community-devel-5.7.17-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

解决:(去掉校验安装)

rpm -ivh mysql-community-devel-5.7.17-1.el6.x86_64.rpm --nosignature  

 

 

2.木有安装 mysql-community-libs-5.7.17-1.el6.x86_64.rpm

[[email protected] tool]# rpm -ivh mysql-community-devel-5.7.17-1.el6.x86_64.rpm  --nosignature
