• 一些问题

（一）apache遇到的问题

1. 在Ubuntu上安装Apache，每次重启，都会出现以下错误提示：

Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName

解决办法:

修改 000-default.conf 文件

打开终端，输入以下命令：

sudo vim /etc/apache2/sites-available/000-default.conf

在文件第一行中加入以下内容：

ServerName localhost

保存文件退出，再次重启apache，错误提示没有了。

2. 启用apache的rewrite模块

sudo a2enmod rewrite

重启apache

3. 重启apache用下面的命令：否则会报错：Invalid Mutex directory in argument file:${APACHE_LOCK_DIR}

sudo /etc/init.d/apache2 restart

（二）nginx遇到的问题

1. nginx配置

 修改 /etc/nginx/sites-available/default 将下面的部分注释去掉

location ~ .php$ {
fastcgi_split_path_info ^(.+.php)(/.+)$;
# # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
#
# # With php5-cgi alone:
fastcgi_pass 127.0.0.1:9000;
# With php5-fpm:
# fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}

(三) PHP遇到的问题

开启某个扩展 如：

#php5
sudo php5enmod mcrypt

#php7
sudo phpenmod mcrypt
