CentOS 7.2下安装部署邮件服务器(Postfix)的步骤详解
本文主要介绍的是在CentOS7.2安装部署邮件服务器(Postfix)的相关内容，分享出来供大家参考学习，下面来看看详细的介绍：
Postfix是一种电子邮件服务器，它是由任职于IBM华生研究中心（T.J.WatsonResearchCenter）的荷兰籍研究员WietseVenema为了改良sendmail邮件服务器而产生的。最早在1990年代晚期出现，是一个开放源代码的软件。
注意：以下所有配置的命名都是根据主机的hostname变量来配置的，如果hostname更换了的话，需要重新生成证书。
生成ssl证书
1、生成证书的脚本代码
以hostname为命名生成证书，运行脚本后需输入四次相同密码(密码须包含数字和字母)
#!/bin/sh rm-rf$(hostname).* opensslgenrsa-des3-out$(hostname).key1024 SUBJECT="/C=US/ST=Mars/L=iTranswarp/O=iTranswarp/OU=iTranswarp/CN=$(hostname)" opensslreq-new-subj$SUBJECT-key$(hostname).key-out$(hostname).csr mv$(hostname).key$(hostname).origin.key opensslrsa-in$(hostname).origin.key-out$(hostname).key opensslx509-req-days3650-in$(hostname).csr-signkey$(hostname).key-out$(hostname).crt cp$(hostname).crt/etc/pki/tls/certs/$(hostname).crt cp$(hostname).key/etc/pki/tls/certs/$(hostname).key echo"thekeypath:/etc/pki/tls/certs/$(hostname).key" echo"thecrtpath:/etc/pki/tls/certs/$(hostname).crt" rm-rf$(hostname).*
