邮件发送准备

安装heirloom-mailx

1)apt install heirloom-mailx -y

如果不能安装则在source.list添加:

    deb http://cz.archive.ubuntu.com/ubuntu xenial main universe

2)获取邮件发送服务器的smtp信息以及密码（不是登录密码）

3)修改mail的配置

vim /etc/s-nail.rc

set from="duskxxxx@163.com"
set smtp="smtp.163.com"
set smtp-auth-user="duskxxxx@163.com"
set smtp-auth-password="xxxxx"
set smtp-auth=login

4)测试邮件发送

 ##这两种方式都行
 echo "hello" | heirloom-mailx -s "邮件主题" -t recive-mail
 echo "hello" | s-nail -s "邮件主题" -t recive-mail

安装megacli

megacli只有rpm包，所以需要在ubuntu上将rpm转为deb包;

获取安装文件

官网下载安装包解压后如下图文件：

此处我是已经转换过后的，所有有deb文件。



将

MegaCli-8.04.07-1.noarch.rpm

转为deb文件

alien -k --scripts MegaCli-8.04.07-1.noarch.rpm

安装

dpkg -i megacli_8.04.07-1_all.deb
#安装文件在：/opt/MegaRAID/MegaCli下
ln -s /opt/MegaRAID/MegaCli/MegaCli64 /usr/local/bin/megacli

到此就安装完成，如果在使用过程中缺失库文件，可以去centos下找到，然后放在/usr/lib/x86_64-linux-gnu下，也可以使用apt-file去安装。

如果有一下提示，可以不用管：

root@localhost:~/MegaCli# megacli -v
