Centos6.6安装sysstat报错/etc/cron.d

为了使用sar和iostat监控工具，需要安装sysstat包，但遇到报错

1.用yum安装

[root@leader Packages]# yum install -y sysstat*
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
Examining sysstat-9.0.4-27.el6.x86_64.rpm: sysstat-9.0.4-27.el6.x86_64

Error: Package: sysstat-9.0.4-27.el6.x86_64 (/sysstat-9.0.4-27.el6.x86_64)
Requires: /etc/cron.d
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

2.用rpm安装

[root@leader Packages]# rpm -ivh sysstat*
warning: sysstat-9.0.4-27.el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
error: Failed dependencies:
/etc/cron.d is needed by sysstat-9.0.4-27.el6.x86_64

原因：

这是由于yum初始化安装时，安装了旧版本的GPG keys造成的

解决方法：

(引入已安装的public key)

[root@leader Packages]# rpm --import /etc/pki/rpm-gpg/RPM*

再次安装rpm包时，后面加上--force --nodeps如

[root@leader Packages]# rpm -ivh sysstat* --force --nodeps
