apache错误：server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName'

linux配置apache环境重启是遇到：

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message

只需要在apache的配置文件 apache2.conf 里面添加这么一句话：

#打开配置文件  sudo vim /etc/apache2/apache2.conf  #加上这一句  ServerName localhost:80 

然后：

#重启Apachesudo service apache2 restart#出现* Restarting web server apache2   [ OK ]                                                                     

问题就解决啦！
