如果遇到：
phpunit....
To enable extensions, verify that they are enabled in those .ini files:
- /etc/php5/cli/php.ini
- /etc/php5/cli/conf.d/05-opcache.ini
....
请安装php-xml的扩展就好了。
如果出现500错误，请检查以下：
1.将项目public目录设置为根目录之后，根目录的设置
这里：<Directory />
# Options FollowSymLinks
# AllowOverride None
AllowOverride none
# Require all denied
Options FollowSymLinks
Order deny,allow
Deny from all
</Directory>
这里
#
<Directory "/var/www/html/ranking/public">
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated and important. Please see
# http://httpd.apache.org/docs/2.2/mod/core.html#options
# for more information.
#
Options Indexes FollowSymLinks
#
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
#
# AllowOverride None
AllowOverride All
# Require all granted
#
# Controls who can get stuff from this server.
#
Order allow,deny
Allow from all
</Directory>
这里：composer install 并且给项目目录添加777 -R权限。
这里：如果使用了git的话 可能要marge这时候执行如下指令：
git fetch --all
git reset --hard origin/master
OK。
