centos yum安装 GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

1、意思是在/etc/pki/rpm-gpg/中找不到RPM-GPG-KEY-mysql

文件

第一种方案，设置gpgcheck为0，就是不需要检查gpgkey。

# enable to use MySQL 5.6

[mysql56-community]
name=MySQL 5.6 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/
enabled=1
gpgcheck=0

#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

第二种方案，指定外网gpgkey的值

# enable to use MySQL 5.6

[mysql56-community]
name=MySQL 5.6 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/
enabled=1
gpgcheck=0    gpgkey=http://springdale.math.ias.edu/data/puias/6/x86_64/os/RPM-GPG-KEY-puias

第三种方案，下载gpgkey

//下载RPM-GPG-KEY-mysql
wget http://repo.mysql.com/RPM-GPG-KEY-mysql -O /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

//MySQL中gpgkey指定路径

# enable to use MySQL 5.6

[mysql56-community]
name=MySQL 5.6 Community Server
baseurl=http://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
