centos安装mysql5.6

查看版本：

[sparkadmin@hadoop3 ~]$ lsb_release -a
lsb version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
distributor id: centos
description: centos release 6.7 (final)
release: 6.7
codename: final

centos默认通过yum 只能安装mysql 5.1

1. 查看系统里面有没有mysql 的repo
# yum repolist all | grep mysql

2. 如果没有发现，则需要配置repo
#vim /etc/yum.repos.d/mysql-community.repo

# enable to use mysql 5.6
[mysql56-community]
name=mysql 5.6 community server
baseurl=https://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-mysql

3. 再看看是否存在mysql的repo
# yum repolist enabled | grep mysql
mysql56-community mysql 5.6 community server 214

4、安装

# yum install mysql-community-server

如果安装过程中报错，没有安装成功：

warning: rpmts_hdrfromfdno: header v3 dsa/sha1 signature, key id 5072e1f5: nokey

解决方法：

# vim /etc/pki/rpm-gpg/rpm-gpg-key-mysql

添加下面的内容：
