httpd服务启动失败

前台打印could not reliably determine the server's fully qualifued domain name ，using 127.0.0.1 for servername

原因：ssl证书过期了

解决方法1:设置禁止检查证书在/etc/httpd/conf.d/nss.conf 加入NSSEnforceVaildCerts off 或者 NSSEngine off

解决方法2:重新生成证书，cd /etc/httpd/alias；rm -f *.db；/usr/sbin/gencent /etc/httpd/alias >/etc/httpd/alias/install.log 2>&1
