Centos6.5 yum安装 MySQL6.5+

时间:2022-11-22 10:25:33

在Centos6.5环境上使用yum -y install mysql 安装的是MySQL5.1


先卸载MySQL5.1

查找 rpm -qa|grep mysql

[root@mysql ~]# rpm -qa|grep mysql
mysql-libs-5.1.71-1.el6.x86_64


卸载:rpm -e mysql-libs-5.1.71-1.el6.x86_64 --nodeps

如果有多个mysql-**的话 就多执行一下命令。



想要安装MySQL6.5 要经过一些改造。

c:

# yum install mysql-community-server

这时安装时会报:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY

由于yum安装了旧版本的GPG keys造成的

接下来需要做:

gpg --import /etc/pki/rpm-gpg/RPM* 
rpm --import /etc/pki/rpm-gpg/RPM* 

就不会报错了。

再执行

yum install mysql-community-server
就能进行安装了。

安装完成后使用

service mysqld start #启动服务

设置root密码

/usr/bin/mysqladmin -u root password  123456


使用root登陆

mysql -uroot -p 123456

解决。
