报错
httpd: apr_sockaddr_info_get() failed for XX（主机名）
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
打开主配置文件httpd.conf
找到修改 ServerName 主机名:80 （删除注释）
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName qiangqiang:80
#
# Deny access to the entirety of your server's filesystem. You must
# explicitly permit access to web content directories in other
解决这个问题可以设定 ServerName 和在 /etc/hosts 中填入自己的主机名称 MYHOST，像这样：
1.查看主机名的命令是：hostname
- 设置主机名
vim /etc/hosts
127.0.0.1 localhost.localdomain localhost XX（主机名）
127.0.0.1 localhost.localdomain localhost qiangqiang
::1 localhost6.localdomain6 localhost6
